Official Acer Aspire 5739G Owner's Lounge

But how you guys doing that you don't have problems with overheating? After I put M4000 in any test (benchmark or game on higher graphic settings) I have about after 5 minutes critical temperature... I admit - I dont have the best thermal paste (I'll put ArcticSilver5), but there is no dust inside, and everything looks fine...

Also Im givig my GPU-Z screen and 3dMark06 (very low! - why?) results...

http://www.3dmark.com/3dm06/17556730

 

Just apply more amount of thermal paste on GPU chip. I had the same problem. Solved applying more thermal paste.

 

Hmm, if you say so... That's a pity there is no more place to put bigger radiator or second fan
Did you look on my results from 3dmark? How does it look generally? I saw that other notebooks with M4000 had much better results... Processor? Motherboard? Or just software? I dont really know

 

Mainly laptops with M4000 onboard by default are much more powerfull than our 5739G, because they have core i processors, better ram and so on. For the laptops of 5739G generation, these results are outstanding. By the way, I had 13k+ scores in 3dmark06.

Actually I`ve tried to install additional fan. I`ve managed it partly. It is working, but I have 12V additional fan, not 5V, as original. So I had to help him to spin up using fingers or something else. At this moment the fan is de-attached.

 

ok for everyone using the m4000 firepro card i have modified the 64bit HP Firepro Drivers allowing you to install them with the dell m4000 card on an acer laptop.

uninstall all your ati drivers
extract the modified drivers
go to device manager and then your graphics card properties
go to update driver
browse to \firepro m4000 drivers\Packages\Drivers\Display\WB6A_INF and select C7164036.inf

select the m4000 firepro card, it will come up as unsigned driver because it has been modified

once it has installed run the catalyst installer to install the rest of the firepro drivers and software.

Download firepro m4000 drivers.rar from Sendspace.com - send big files the easy way

 

Thank`s! I`ll try them and post the results.

EDIT: Unfortunately, I`ve not managed to install these drivers. In installation process windows promts, that these drivers are not supported by this version of Windows.

 

what version of windows are you using? i have tested them on 7-64.

 

WIndows 7 Ultimate x64. The same as yours, I think.

 

Is it the dell or HP card your using?

 

Dell PR80-C.

 

Hi guys,
Finally i got my M4000 and T9900 woohoo !!

Ok here's my CPU:

1. Any idea of how to know if this is the real SGLEE T9900 ? I saw the label SGLEE on the chip but can it be faked ? The reason I'm so skeptical is bcoz i bought this one from China with 109$ and after a bargain i got 30% discount because of 5 bent pins

Next is temperature:

I tested with a few apps running, a HD video running and Dynasty Warrior 6 max setting at the same time for 10 minutes (didn't have 3dmark unfortunatly, I'm downloading and will post my result right after a few minutes ).

CPU reach 75 and 76 for 2 cores
M4000 is 65

Temp before test (idl) :
CPU : 35 and 41 for 2 cores
M4000 : 46

Temp after test (idl) :
CPU : 48 and 50 for 2 cores
M4000 : 59

2. So what do you think guys ? Is this good ? I didn't use AC fan control and only applied thermalright CF3 for M4000, T9900 i didn't even cleaned the old Intel paste (applied for 5 days) because i dont have the paste here.

3. For some reason this thing happened to me

Same goes for you ? Why is there so many of them here ? How can i delete them coz i only need one for my HDMI. Oh and i can not export sound to LCD using HDMI cable, only picture, can anybody help ?

 

Your temps are very very good. Even for T9900 and M4000 thay are low. And even without applying new thermal paste. About CPU, SLGEE = E0 Revision(stepping). Thus, you have SLGEE processor.

 

Hi,

I am running my Acer Aspire 5739g pretty standard right now.
- CPU: P8700 (already upgraded from T6500 some time ago)
- GPU: GT 240m
- RAM: 4GB
I started reading what possibilities for an upgrade i have and saw how you all fancy the m4000 card and that the t9900 is the top cpu.
So I basically have a money problem, or else I would probably get a new desktop but i need a bit more gaming performance for as little money as possible. No high end games, just WoW or World of Tanks and stuff.
I found this dell m4000 for 75€.
but now I have a couple of questions to propperly prepare myself for the upgrade.
1. If I only get the m4000 will my other parts bottleneck the performance?
2. judging from the paper values I estimate a performance increase of 20% if I get t9900 ( source). is this correct? is this worth the ca. 120€?
3. and considering RAM, 1x4GB is around 35€, what happens if I only buy one module and use a total of 6GB RAM?
4. If I actually get there I could need a good summary what I need to do in preparation of changing my video card.

 

Hello, robozu!

1. Your CPU may bottleneck the GPU.
2. Yes, it is worth to spend such money. But, remember, that you only need SLGEE version of T9900.
3. Nothing. Plug and play, as I understand. Both RAM freq. must be the same, as a timings should be the same too.
4. Look through pages back, I`ve already explained several times on how to correctly swap old card with M4000.

Don`t forget to clean old and apply a new one thermal paste on CPU and GPU.

If you have additional questions, feel free to ask!

 

so today I got my m4000. T9900 still on its longer way.

I get a picture, so that is something.

- removed the nvidia driver and software
- removed gt 240 m
- removed x-bracket from m4000 (whch is glued to the card with some sort of double sided tape)
- switched on laptop
- used auto detect by amd
- installed catalyst mobility center

and now the big question is what card do I have? software calls itself amd firepro controll center. hardware info tells:
chipset: AMD Radeon HD 7700M Series
device-id: 682D
it got 1G gddr5, 675MHz core, and 1000MHz ram clock
so i guess its the actual firepro m4000...
anyway. thanks for the info from the board and I will report back with my t9900

 

Congrats! Now you are owner of the currently mightiest card available for this laptop! Yes, you have M4000. First, M4000 is made on the basis of 7770M chip. Second, if it is recognized in Device Manager as 7770M, probably it has 7770M`s vBIOS. That`s OK. I saw how some users have modified their 6770M with M5950 FirePro vBIOS, in the Device Manager it was than shown as M5950. And vice versa - M5950 was modified with 6770M, recognized then in Device Manager as 6770M.

Good for you, that AMD auto detect for you worked. I was pissed off at first, when I was trying to install drivers for my M4000.

 

Hello friends and fellow 5739g owners.
I hope you could give me some suggestions because i'm really at a dead end here... My laptop overheats (classic)...
First of all my setup
Intel p7450 2.13ghz
Nvidia GT240M
2X2GB ram
Crucial SSD M500 120GB

Now, i have tried... Of course first of all i cleaned my fan, it is really spotless. Nothing happened, i went and bought new thermal compount, after some research it seemed to me that the best bet was the arctic silver MX-4, so i bought it, then i fully disassembled my laptop, scraped my old compound and cleaned all the heat sinks with isopropyl alcohol, I applied the new compound with the standard method (a drop of pea sized compound) and assembled the device back again. For the first two weeks, it worked perfect with temperatures never exceeding 60 deg. Until it started again, first under load (light gaming) then every time, just light browsing and it's fired up. I once again cleaned and re applied the thermal paste. Again the same, first two weeks, under heavy gaming the laptop was ok, after that, again overheating all the time. And when i mean overheating..
I have right now the main plastic cover removed, placed my laptop between two books to have a good gap underneath for easy breathing and right now my gpu is on 79, my cpu on 75 and even my ram is so hot that it bothers me while im typing. And the workload for all of that heat? Newly freshly instaled windows, and the only thing open right now: google chrome 5 tabs.
The device is not overclocked in any way...What can i do? It's driving me crazy!!!!
Thank you in advance for your help

 

When disassembled the laptop for the second time, in which condition thermal compound was? I would recommend you to apply a thin layer of thermal paste on the CPU and GPU, not the small drop of thermal paste. That`s the first. Second, in which condition are thermal pads of the VRAM of the graphics card? Third, haven`t you bent the heatsink? In addition, try AcFanControl utility to manually adjust the cooling table of your fan.

 

Hello propolkin, thank you for your reply..
What do you mean what was the condition of the thermal paste? I don't know, it looked like when i applied it, it wasn't "dried out" if that's what you mean..
So you recommend me to spread somehow the paste on the heatsinks and the cpu gpu? As for the thermal pads, yes that's one thing, the visually seem worn out, but where can i get new ones?
I haven't bent the heatsink? should i??? :S
And what drive me crazy is, why does it work well for 2-3 weeks, then suddenly starts overheating again?? if it was the thermal pads, or a bent heatsink or something like that, shouldnt it keep overheating anyways???
I just downloaded it and i will check it out, though ive tried other programs too, none of them could manage my laptop fan...
Thank you very much for your concern, cheers!

 

Yeah, I mean was it or not dried out. Take your plastic card or something like that and spread the thermal paste on the chips. Use these or these thermal pads for VRAM.

Nope, of course you don`t have to bent the heatsink. Why I`m asking: sometimes people make that mistake when they are trying to remove cpu/apply new thermal compound. And yes, your are right - if the HS was bent or damaged, your laptop should be always overheated.

Maybe the problem is with thermal paste. Strange. MX-4 is good thermal compound, as I know. I`m using Arctic Silver 5.

About AcFanControl - this utility has to be configured in order to control the fan. Browse the Acer Aspire forum, there somewhere is thread about this utility, showing on how to configure it.

And the last - I had something like your problem. One of the programs had virus, that uses GPU on 100%, when NVIDIA start update service. That`s why my laptop with old GT240M have been overheated until shutdown. But I don`t think, that your problem is related to the software issue, because you have re-installed Windows two weeks ago, as I understand.

Guys, what do you think about that?

 

Thank you so very much my friend... Something else i noticed is that the first thing that spikes in temp is my chipset...then nvidia which if im not mistaken (if i do please correct me) is right on top of it... Maybe that is the source of the problem... again if i remember correctly it has a thermal pad, hope the new pads will solve it.
The reason i went for mx-4 is because it is ceramic based unlike arctic 5 i think so it's less electric conductive, if i dont see any progress i will for sure change it to arctic 5 since you use it and you are happy with it on your aspire.
Speaking of which.... Daaaamn ( ) you have such a nice setup, i would really appreciate if you gave me some links on your build so i could get informed, if it doesnt cost a fortune, i really consider an upgrade like yours.
P.S. That keyboard is the s*it!!! hehehe thumbs up from me!

 

Chipset is on the up-right of the GPU, another chipset is under GPU. Don`t remember, what does this chipset, but it has the thermal pad too. I don`t think, that a northbridge (chipset on the up-right of the GPU) is overheating. But you can attach a radiator on it using thermal conductive glue.

AS5 is not electrically conductive.

So, about links. Here you are, these are link from ebay:
M4000 with vBIOS onboard
T9900 SLGEE (E0)
X9100 SLB48 (C0)
RAM 1x4Gb 1066MHz DDR3 SODIMM

And from Aliexpress:
M4000 with vBIOS onboard
6770M RED PCB with vBIOS onboard
T9900 SLGEE (E0)
X9100 SLB48 (C0)
RAM 1x4Gb 1066MHz DDR3 SODIMM

aliexpress is not so expensive, but, for me, I trust ebay.

About CPU. I have X9100 C0 45W. It is much hotter than E0 version of X9100. The only advantage of X9100 - it has unlocked multiplier. It can be overclocked without SetFSB. T9900 E0 is 35W and don`t have unlocked multiplier. Other specifications are the same as for X9100. But, T9900 is not so hot, as X9100. SO you should decide, are you planning to overclock your CPU or not.

And in addition, if you are planning to buy M4000 - search at this thread, I and other users, that were the first who bought that card for 5739G, have described the correct installation process.

EDIT: And the last - the main problem you`ll face - overheating. You should use very good thermal pastes and thermal pads. For example, those, that I`ve shown you some posts back.

EDIT: P.S. working AcFanControl would be great advantage over standard cooling table of the BIOS. And of course nobody restricts you to use hardware mods such as I have done (and some other users from this thread) for several times - installing second fan, manual control of the fan by the special circuit, custom-made copper radiator for the CPU heatsink plate... and so on. But this is out of normal upgrade, that`s for maniacs, I think. But it has its results. Nevertheless, second fan and radiators are removed for now.

If you have additional question, feel free to ask.

 

You can always buy QHBQ (X9100 E0) If you don't trust this particular seller (since he has no votes) search for QHBQ there are a handful, a bit more expensive though.

 

Yeah, and it is working good too.

 

Guys thank you very much, you have been more than helpful, now what i need to do is learn how to operate the acfancontrol!! And about the hardware mods regarding the temperature drop, i am mooore than interested, call me a maniac but im so tired of it overheating that i want to do what's best in my hand to keep it cool that i simply dont care!! I dont care about operating noise or system weight... i dont care about anything, either way this is something of a desktop replacement laptop, i only move it once a week from one house to another, i dont carry it around with me. Have you posted guides on that matter on this thread? 138 pages is really a lot to go through, do you remember maybe roughly (+- 10 pages) where is it posted? Thanks again!!
As for the cpu, i think i'm gonna stick with the t9500, an extreme edition would be really nice, but i think i should better keep it on a budget. Unless a good opportunity arrives...god bless ebay hehe

 

Sorry, I don`t remember the pages. Use search function. On the first half of this thread there is circuit diagram of the board, by which you can control your fan manually. On the middle of the thread, if my memory serves my well, there is diagram of the custom radiator.

About CPU - if you don`t plan to overclock, than buy this one. This CPU has only 25W and 2.53GHz 1066MHz. And it is not so expensive.

About AcFanControl. I`ll post my setting in the evening. Maybe my table will fit for utility. Oh, don`t forget to update sBIOS to latest version. You can find it on acer home page. Updating sBIOS is always risky, don`t forget it.

In addition, you can stick cooper radiators to the heatsink. It will drop some degrees too.

 

Thanks mate, hope it does? And how do i import your settings? I've been monitoring my system for some days now, the cpu seems to be ok (even while gaming it does not exceed 70deg), the problem is at the gpu, it most definitely is the thermal pads... Can't wait for them to be delivered...
Thanx for your tip regarding the cpu!! As for the bios, i have already updated them to the latest version (3310)

 

You are welcome!

Here is installation, config and table for the AcFanControl. First of all, install AFC, than copy ACFanControl.ini to installed folder. Maybe it will works as intented. If no, there is third file, called AFC_table.txt. Use it to configure utility.

At this moment utility is configured as follows:

// Celsius/FanCtrl/BiosCtrl/CtrlNWrite

Level=10 250 128 0
Level=40 3 128 0
level=45 4 128 0
level=50 5 128 0
level=55 39 128 0
Level=65 39 128 0
Level=75 39 128 0
Level=83 39 128 0

It is switching fan speed on 10, 40, 45, 50, 55. After 55 C fan will be spinning on the max speed, that this utility can send to our fan controller. After 85 C the ACF will switch its control to BIOS control.

When the utility is configured and launched, you I`ll see its icon on the bottom right sight of the desktop. Click on it with right mouse button and press "Smart Mode". Now the fan will be controlled by the program, not by the BIOS table.

I hope, that this short manual will bring you understanding on how to use ACF.

 

You are just THE MAN... Thank you very much mate! Works like a charm... A quick update, couldn't wait for the pads anymore and i took charge, opened the laptop once again and that time removed everything for good, old thermal paste and pads and replaced it all with the arctic silver ceramique 2. I think this is the less electric conductive paste in the market... very thick compound too, i applied it, got rid of the pads and things seem to go fine. Right now for example with you new ini file im at gpu 35, cpu 40 idling with just chrome on. Lets hope it stays that way...
Another fun fact... after i applied it, i found a new compound which is sold to specially replace those thermal pads, they mainly made it for the imacs and stuff but works just fine for us. And the funny thing is that the company that made it is from my city excactly. They say its way better than pads since its more heat conductive. I don't know, check it out, tell me what you think guys

it is great, that you`ve reached good temps!

Interesting thing. Is there any link on its specs?

 

Since its quite a unique product i guess, they dont say an awful much about it, all i could find is this:
K5-PRO is a high quality gummy thermal paste designed for use on memory chips and GPUs of various computers including Acer Aspire 6930 , Apple iMac A1228 video boards. This is the only comercially avaliable product at the moment that can replace the gummy thermal paste that is originally used by Apple.
K5-PRO can replace soft thermal pads that are used on computers (up to 3mm thick)
K5-PRO has thermal conductivity K>4W/mC * (at least 3 times higher than common thermal pads that are used on computers and comercial electronics)
K5-PRO is applied very easily directly on the component and has practically zero electrical conductivity. It can be heated up to 250 degrees (Celcium) and has a long operational life time (more than one year after the installation)

* Computer Systems matterials science laboratory testing : Method using a comparative technique (P. Karydopoulos, P. Frantzis, N. Karagiannis MSAIJ 2014)

And i just found that, they say it's a promo, so for anyone that wants to test, i'll just leave it here:
K5 Pro Gummy Thermal Paste Grease for Thermal Pad Replacement 20g A1228 | eBay

Hope i helped, i will give it a try soon myself and when i do i will sure let you know guys if anyone hasnt tried it since (which i highly doubt )

 

Those thermal pads has 11.0W/mC thermal conductivity. Thus, they are better, than this substance.

 

:hi2: I'm new to the forum, but owned the Aspire 5739G close to 5 years now (bought new with extended warranty which wasn't useful with this nice laptop) absolutely LOVE this laptop. So far did couple upgrades (mostly CPU's) but also maxed out ram and brought new life into it with Samsung EVO SSD. Now I found good deal on ebay for blue (HP branded) PCB HD 6770 MXM type A that should work in this laptop but after buying found posts explaining why it's not plug and play (you guessed it it's ROMless version). For now asked selled to cancel transaction, but I was wondering if anyone had SUCCESSFULLY integrated vBIOS for this exact version of the card into 5739G sBIOS? I read the instructions but since programming isn't my forte too scared to mess with BIOS flashing (for me soldering BIOS chip would be actually easier since I'm pretty good with SMD soldering but then it also requires flashing the chips BIOS which to me was a slightly complicated story to read (the fact that I was doing this at 1 AM ( 1 at night) didn't help as well. SO long story short I read through most pages of the thread but maybe I missed if someone did manage to incorporate vBIOS into sBIOS (latest version is v0.3310 I think) and if they did do they have by any chance that BIOS? Thank you in advance guys (and girls if any ).
P.S. I do realize I can get M4000 with ROM chip from China but it's almost 3x price than HD 6770 which doesn't justify the performance difference for me (I know if I was performance gain hungry it's all good ). I did get P version of the CPU (to cut down power usage by 10W which would be beneficial for the extra that better video card will bring in)
Current Configuration: P9700 CPU, GT 240M 1GB DDR3 Video.
P.P.S. Ok thanks to guides and posts on this and other threads I kind of figured it out (integrating vBios into sBios) BUT first precaution for 5739G owners out there the latest BIOS is V.3310 NOT .3311 because I almost bricked mine trying to upgrade it to later (in the folder name is even says Extenza 5320 I think so it might be just misplaced BIOS.I did added it as additional video rom since I only had 5 (0-4) original ones two for Intel VGA one for Nvidia and 2 for some other hardware. I haven't received the card yet but laptop works after update and hopefully once I install new video card will be recognized without problems

 

That`s are good news, Sanek1982!

I thought, that 3311 is the latest version of BIOS. Need to check mine after work. Thank`s for the information.

I hope that your card will work as intended, when it arrives!

 

Hi Everyone!
I'm new in The club. Thanks to community I' ve bought T9600 and now I think about change of graphic card.
What do You think about Dell AMD FirePro M4000 Mobility Pro with 1GB GDDR5 for Precision M4700 3YF07 | eBay. Will it be acceptable with our Acer?
Best regards

 

Hi there!

Considering your upgrade of the GPU: yep, this version of the card is fully compatible with our laptop. Before the installation don`t forget to remove X-bracket. If you have any other questions, feel free to ask. And don`t forget about good thermal paste for it and thermal pads.

100% compatible drivers for this card: AMD 7770M drivers from amd.com.

 

I got card today (removed x-bracket by installing long screws that fit the thread on it and slowly while heating with fan pushed on the screws while holding the board in place, after one corner started to pull off, rest went off easy). Unfortunately my new card did not produce ANY video ( I tried the hdmi and vga with no video out on them either). It seems that laptop boots up with hard drive and all the lights working, but nothing on display. At this point I reapplied paste to core and installed new thermal pads on ram and voltage regulator on the old card installed it and it works like before. So the new card is not doing what it should, I'm wondering if I integrated vBIOS into sBIOS wrong way or the card is not good
P.S. Ont the other note the seller didn't pack it inside antistatic bag which makes me think that it fried it during shipping

 

Ask Valuxin help - he can correctly integrate your vBIOS into sBIOS. If after that the card won`t work - ask seller for the refund.

 

I tried sending him friendship so I can send PM him but haven't gotten any reply from him. I'll try dell vBIOS instead of HP after work, maybe that will help.Also did you modified your laptop heatsink to cool down voltage regulators(small grey squares on the video card because they can get very hot from demanding usage)? because stock heatsink doeesn't cover them unless card has same design as original (I think hd 5730 is the most powerful one that retains same layout) hd 6770 (m5950) does not and M4000 (hd 7770m) has even couple extra from the left side of the board.

 

I just used new thermal pads with 11W/mk heat conductivity. That is enough for me. My card is not heating more than 80-85 C in Furmark. While gaming, I saw max. temperature only about 70-75 C.

 

Well I tried using dell vBIOS with the same no video on screen outcome. If I add vBIOS as additional optionrom I can flash sBIOS without problem but nothing is displayed on screen, if I try instead to replace intel VGA optionrom that comes with original bios with an ATI one I get error message and windows crashes when I try to flash system bios. I only have .WPH and .BIN files in my rom folder no .ROM file, so I'm wondering if there's something in the .BIN one that points system to optionroms in the .wph one and tells them to use them, and by replacing one of the built in roms it gets confused because it refers to different vbios (ati instead of intel), same way if I add new rom but there's no link to it in the .bin one system doesn't see new optionrom or recognizes it.
P.S. Tried renaming .bin to .rom and go through all the steps in the guide(renaming it back to .bin after editing), didn't get any error message flashing even though ati vbios replaced intel vbios, but still nothing from the card, just black screen. I give up I'll just buy one with the rom chip and be done with it (hopefully the one that works this time).

 

I hope that with ROM chip it will work as intended. Basically, I think of 95% it will work.

 

It did I got red PCB version from dell I think with GDDR5 memory (they also have slower GDDR3 which can be recognized by smaller size memory chips which are rectangular instead of a square), installed it, booted up, reinstalled drivers and it works great,got recognized as HD 6700M series. The screen looks more vivid (might have been setting with my old nvidia), got only 0.5 increasement in WEI (from 6.4 to 6.9) but real life performance in noticeable even when browsing the internet and playing video. Unfortunaly the heat is up as well (logical since GPU has more power) my chipset heat is up to 75-80 C from 60-70C like before and video is around 20C higher when in high usage ( @ idle difference is smaller)

 

Congratulations with successfull 6770M upgrade! Those temps are not so big. But, if you want, you can drop them by using my methods.

What software you are using, that can provide us with the chipset temps? Does our chipset has thermal sensors?

 

Yes from what I understand acer MB with MXM slot has sensor on the northbridge (southbridge doesn't get that hot so I guess they omitted installing one) I use CPUID HWMonitor and the first reading on the top is for Chipset ( Acer JM50-MV THRM) mine is usually 45-80C with new video card followed by temps of the CPU cores (35-65 for my [email protected]), Samsung EVO 840 @ around 30-35C, and finally Radeon 6700m with 45-65C. I tried undervolting CPU with no real benefit since P series already come with smaller TDP package of 28W max they use generally low voltage and only increase it with big demand, when I tried undervolting I experienced slow downs and even freezes with playing HD videos and streaming media so I went back to system management by using speedstep.

 

Thank you for good overview information! Forgot about that utility.

 

I find my southbridge gets very warm indeed. I have mini heatsinks pulling some heat away. Also my northbridge temp was resetting with my old 6770m. This was causing fan control problems. With my 7770m this is not a problem anymore.

Yeah, 7770M/M4000 has very good voltage control system, that really prevents overheating.

Damn, how "strongly" I want to test my system with that beast... Interesting, does the PSU will be able to connect enough power to the laptop with such video?...

 

Maybe with 120W adapter or 150W one the 90W will die for sure, question is how fast lol.Your biggest problem would be heat though I think. At this point just find used Precision 6600 (something like this Dell Precision M6600 i7 2640M 2 80GHz 4GB 750GB 548 | eBay) and you can even enjoy core quad with up to AMD FirePro M8900 I think plus not worry much about cooling problem.

 

Hello!
I've installed my FirePro 4000m in my laptop and with Intel T9600 (FSB 266 MHz) on board I can say it is completely different PC.
However I know that it can be faster, so there are few combinations that can give me/ us another performance boost:
1. change FSB from 266 MHz to 333 MHz-> I need to buy new RAM for example RAM SAMSUNG 8GB 2x4GB DDR3 1333MHZ SODIMM 2x 4GB (4215171472) - Allegro.pl - Więcej niż aukcje. and then using setfsb_2_2_134_98 change FSB to 333 MHz. Is it possible to gain stable system with that FSB?
2. Buy new CPU-T9900 for example NEW Intel CORE2 T9900 3 06GHz 6M 1066MHz 45 Chipset Only Shipping TO USA Free | eBay or Core 2 Duo Extreme q9100 Intel Core 2 Extreme SLB48 X9100 3 067GHz 6M 1066 Socket P Tested Paste Included 0735858203050 | eBay. But are they:a ) worth the price ; b) will they have enough power from PSU and efficient cooler (mine is ADDA). After applying T9900 or q9100 is it possible to change FSB -> look at point 1.
3. Change FirePro 4000 to: a) FirePro 5100 NEW OEM Dell Precision M4800 AMD Firepro M5100 8800M Video Graphics Card 51Y08 | eBay or
b) quadro k2100 Nvidia Quadro K2100M 2GB N15P Q3 A1 GDDR5 Video Graphics Card GPU K1100M K3100M | eBay?
But we must remember about two things: a) energy consumption of both cards - can our 90 W PSU give the right amount of energy to laptop whet we will change CPU to T9900 or q9100 from point 2. and b) is our cooling system enough to them. We do not want any fire during CAD working or playing computer games, c) noise of cooling system [dB] - It is also very important during work.
And the final question which video card is better Nvidia (with Physics-> Batman ) or ATI ( I couldn't find in Internet information about it power consumption).
4. I tried to find PSU that is able to give our Aspire 5739 more than 90 W and I found zero capable Units. So can You find any?

Maybe official Acer service desk can answer for all this questions? Can you ask Your national Acer representant?
