My 5920g...WITH A HD 4650! (need help)

yeah, couldn't help myself.

 

Gpu tool can control laptops fan I tried, you can attand manually or at constant temprature.

 

Guys new Acer 5739G, new NVIDIA® GeForce® GT240M with 1GB GDDRIII ,
The GeForce GT240M also supports CUDA, DirectX Compute, OpenCL, and PhysiX

The performance of the middle class gpu GT 240M should be somewhere between the GeForce GT130M and the 9700M GTS and above the GT 230M because of the lower clock rate

Pipelines 48 - unified
Core Speed * 550 MHz
Shader Speed * 1210 MHz
Memory Speed * 800 MHz
Memory Bus Width 128 Bit
Memory Type DDR3, GDDR2, GDDR3
Max. Amount of Memory 1024 MB
Shared Memory no
DirectX DirectX 10.1, Shader 4.1
Current Consumption 23 Watt
technology 40 nm; 174 Gigaflops

Are you thinking what I think? Should be cooler(23 watt not 35 wat) and PhysiX support, ddr3 should be better than 4650 ddr2 but price (oh nvdia I'm afraid more than 300 usd) but yummy. Somebody please try...

 

That would indeed be a huge gain, but the pic on Notebookcheck's review doesn't show it as an MXM-II card; it's either MXM-A or MXM-B.

Time to face it, kiddies - Acer's transitioned to MXM 3.0. Which means that the Radeon HD 4650 DDR2 (for most) and the GeForce 9600M GT GDDR3 (for few) are the best upgrades for now, and quite possibly for the rest of the platform's life.

 

Still the 4650 DDR3 MXM II in the MSI is a bit better than the 240M DDR3 which is probably by the looks MXM-A. I think we should probably await for the new ATI mobile cards with DX11. Of course those will come late this year or early next year but still they would be better than the current generation. I have lost my faith in the nvidia cards and I don't expect anything more from nvidia. They will be again re-branded cards with just DX11, nothing more. No wonder why ATI has won the mobile discrete GPU's market and the future looks promising for them.

 

4670 ddr3 from MSI EX625 675-800 stock, amd I still hope Samsung R522(or smth like that) has 4650 ddr3 600-800 (some guy says he saw 700-875 in Turkey) are last options if Acer decided to use mxm-a as a new factor I don't think there will be any upgrade optios.

 

The HD 4650 GDDR3 is better than the 9700M GT but not by much, and the GT 240M has 50% more shaders than the 9700M GT. The 240M GT GDDR3 should beat the HD 4650 GDDR3.

 

Agreed. But it doesn't change the fact that Acer is moving away from MXM-2.

Thats why I jumped on the 4650 when I did. My next move will be a new laptop for sure...one with an SSD, an LED screen, and a great GPU.

 

This Bio Editor sounds interesting.
Will this work with my Studio XPS 4670 too? Where can I download that programme?

Cheers

 

Hi there Nuke33, i just did your mod using prepaid phone cards and it dropped the idle temp of my cpu to around 49-50+ though under load it still reachaes 90-93c, had my 5920g for about 2 years now and also planning to purchase a HD4650 also, got any more tricks to help me with cooling my lappy down?

 

Undervolt as described in my first post...should give you 10C or soo less in GPU and CPU.

 

Thanks classic77, you are a legend here in the philippines, you gave hope to 5920 and 7720 users here, will be purchasing the 4650 soon...anyway right now im using 8600m GT DDR2 and undervolting is not an option for me, i have a T7500 CPU and what are the disadvatanges..if any , if i consider undervolting the CPU, plus my only option is RMClock right?

 

There isn't really any disadvantages to undervolting...actually if you undervolt your CPU, it will result in your heatsink structure being cooler, which will allow your GPU to run cooler as well. There's no reason not to.

lol, I'm flattered.

 

Can we only buy 4650 from acer parts?
Or would any other 4650 boards sold elsewhere work?

 

Great to hear your results are impressive, i never reached 50°C idle with my 8600m GT it always stays at around 59-60°C even though i applied a 0.3mm thick sheet of copper recently. Maybe it´s connected to my cpu although both our cpus have the same tdp of 35W.

Next thing i am going to do is to build some sort of a backplate heatsink with some thermal gap pad to prevent conduction and direct heat away from the backside of the gpu. I know of desktop cards that the gpu backside is almost as hot as the foreside.Another side effect would be that the pressure onto the heatsink is more balanced.

Ahh, and you should really use Dox Customized Forceware 185.85. Best driver i´ve used so far. Got 4505 points in 3dmark06 with just memory overclocked to 493mhz in windows7 x64. Undevolting your cpu would give you massive temperature improvements too.

Have fun tinkering around


EDIT:

Woow i just read through your post another time and saw that your CPU temp is reaching 93°C. Thats REALLY BAD. Max temps for cpu should be 70-80°C. I hope its a typo otherwise your cpu be short lived. You should exchange your thermal paste as soon as possible. Thats the most important step right now. Acer Service Manual should help you disassemble the heatsink. http://printer1.blogspot.com/2009/01/acer-aspire-5920-service-manual.html

 

93C is fine. Hot? yes!!! but according to Intel, it's fine. 97-99C i would start to worry.

http://processorfinder.intel.com/details.aspx?sSpec=SLA44

 

I agree with Darth Bane...I wouldn't be TOO worried...

That is really hot though. What processor do you have? If its a 5920g it probably to be a T5XXX. My T5750 runs at about 70C under load...so I don't know why yours would be so much hotter...

EDIT: I see you have a T7500. It runs at a slightly higher voltage than my T5750...maybe its just a hotter CPU...although that is a significant jump...

Is there any other 5920g owners with T7500s that could confirm this is a normal temp?

 

Yes you´re right but you have to consider 100°C is the MAXIMUM temperature and he is just 7 degrees below. Imagine a hot day and some gaming, that could probably kill the cpu on the long run.Using electronic devices at nearly max specification will decrease lifetime a lot.

Undevolting would be a good start as it has no performance decrease, longer lifetime, better temps and battery saving. It´s a win:win

 

Ok now, RMClock to undervolt...that shall be the first step ill consider....back then when my 5920g battery still works and am using the supplied acer 19v adaptor my cpu temp never went above 80c+.....

I started noticing my temps reaching up to 93c+ when my battery and adaptor broke,right now im not using any batteries, i am using a multivolt generic laptop adaptor with voltage ratings from 15v-24v at 4.5amps, i had the adaptor set to 18v, running it at 19v game me 95c+, my question is...the rated amp listed at the back of my laptop is 4.7amps, correct me if im wrong, im using an adaptor that can supply only a maximum of 4.5amps...is that good or bad? In short...i want my old temps back!

Another question....what is the recommended undervolt temp for my T7500 ?

Thanks guys for the replies, am still saving enough money for the HD4650
Right now i got my 8600mGT DDR2 running at :

GPUCOREMHZ0=580
GPUMEMMHZ0=472

I am thinking of ways to drastically lower my temps...maybe a case mode for my 5920g

 

Wow, another member from Pinas!

When undervolting your CPU, the least you could get is about (I think) 8*C.. I think the most I got was 10C off load temps, and about 12C off idle temps.

 

I would buy an original Acer adaptor to be sure.
What are your gpu temps while gaming ? overclock of 100mhz core with my 8600m GT resulted in peaktemp of 97°C and throttling. Though this was with the supplied thermalpad. with a piece of copper and mx-2 it´s maxing out at approximately 92°C.

I would recommend you not to overclock core or shader much. Memory is not giving much higher temps. Mine maxed out at 493mhz.

 

Ima go wait a few more weeks before purchasing a 4650 module too....meanwhile i undervolted my T7500 cpu to 1.1v and my 8600m GT i set every performance level to .8 volts and i was surprised with the temps

Gpu temp : idles at 50-60c, 80-85 c max (OC'd at 580core, 1160shader, 472 mem) running furmark, atitool, crysis warhead

Cpu temp : idles at 40-50c, never rose above 85c during stress tests with intelburntest , linpack, orthos, during gaming rarely reaches 80c, temps under load during heavy gaming hovers usually around 70-73c

finally, after the credit card mod shown here plus undervolting i got a slightly cooler lappy running.....

 

Nicely done!

 

Wow congratulations, really nice that you managed to undervolt your 8600m GT

what have you done to achieve this exactely ?

 

Nibitor + Nvflash + a bootable usb with DOS for flashing the bios witht he new voltage entries.....default was 1.25v for performance mode, i set mine to .8v under every mode and i was very surprised that i can still OC 580core, 1160 shaders, 472 memory with ease and temps rarely reach 80c+ even with OC.


Is there any way to permanently underclock the T7500 without using rmclock? im not very fond of having it running in my systray all the time...

 

So 8600M GTs are in fact undervoltable. I don't remember who exactly but he assured me that the 8600M GT wasn't undervoltable. 1,25V to 0,8V and still having OCing abilities----> Very impressive. Nvidia gpus roxxx with low voltages.

Nibitor + Nvflash + a bootable usb with DOS for flashing the bios witht he new voltage. I used exactly the same method for my 9600M GT. I played Wolfenstein during 3 hours yesterday with almost all settings maxed out except AA and gpu OC to 600/1500 and got only 78°C max. I still hardly believe it sometimes ;-)

 

AFAIK nope. I would have done it if I could find out how.
I heard about some PIN mod or something but i'm not sure.
However, with my P9600, it wouldn't be that useful cause it's pretty cool even without UVing. The highest FID has its voltage originally set up to 1,05V so compared to my old T5800 which was 1,25V, it's an icicle.

 

LOL i play Cod 4 and i get 81-83 celcius at most and my GPU is not undervolted and DDR2 and the processor has higher TDP and somemore COD4 is more stressing on GPU that wolfenstein... nice undevolt u got

 

When i say i can't believe it, it's because i used to get 92°C at full load before undervolting...I'm not claiming that i have BEST temps ever. So i don't care of your temps dude since you experienced no overheating issue AFAIK.

And yeah when you lost about 15°C at full load, it can be called a worth undervolting. You may shut up next time, cocky man ;-)

Edit : In fact i can claim that i have better temps than you cause i've exactly the same temps on COD4 (78°C) on 1280*800 with settings maxed out plus GPU OCed to 600/1500. I will suppose that your mockery comes from some sort of frustration caused by the impossibility for you to play COD4 above 800*600 with your crappy DDR2 gpu May i suggest you to find a place where to hide ??? Peace.

 

Okay i tried it your way. I managed to undervolt my gpu to 1.15V at all levels from 1.25V at performance mode. That gave me a little better temps but not such a huge improvement as yours. I wonder why i cant go down to 0.8V. Could you post your bios to rapidshare please, so i could compare our bioses ?

 

Dont' warry Kallogan, Sean473 is a stupid troll. He always insults other people's systems and brags how much better his own is.

He thinks that his lappy would beat mine in gaming too (he just blurted that out in another thread)....what he doesn't know is how much less important a CPU is than I GPU for gaming, I guess.

 

Here is the link to the bios i used to tweak the settings down to .8v
http://rapidshare.com/files/277984009/TEST.rom.html
This bios is for the DDR2 version of Acer 8600m GT, i hope it works for you, have a backup just in case, plse msg me once the link expires, it can only be downloaded 10 times...free rapidshare account. Take care, hope it works for you too.

 

Use megaupload.com, 1GB file limit, no wait, 1meg per second, unlimited downloads...no account required.

 

Well Sean's wont be faster than mine

 

Thnx, i will give it a try

mhh every thing is the same exept VIDs, Board IDs and Bios Version.

My Bios Version is 60.84.62.00.29. My VIDs are 1.15, 1.2, 1.25, 1.32. Board ID : F414

I dont know if it is a good idea to flash it with your bios since you have a older version and it seems that your card is using completely different VIDs. I will wait till my 4650 arrives and then give it a try.

Anyone got some experience with flashing cards with alternative bioses?

 

Hi i'am new here sorry to ask for but where do i find your mod bios classic77?

I've ordered the 4650 for 180€ in Germany and replaced my faulty
HD3650 (HP vBios Green PCB 256GDDR3) inside my Alienware m5550-R3-i
I boot and runs fine without any problems and idles at 58C currently.

I would like to mod it's Bios and overclock but can you write some rough How two? I've done that before but on desktop and years ago ;-(

Thanks Classic77 you are my hero when it comes to mxm upgrades this time.

Anyone knows how slow DDR2 is compared to DDR3, is it very BAD?

 

Anyone knows how the DDR2 which is slow compares to DDR3 is it very BAD?

Not very bad it can easily see 600-650Mhz with o.c. and hp's ddr3 one is 667Mhz.

 

classic77! Are you still looking for a copper shim to put in your 4650? I think I found something of interest:

http://cgi.ebay.ph/DV9000-Copper-Sh...s_RL?hash=item25566a8cc3&_trksid=p3286.c0.m14

(it's in ebay.ph, but location is in UK, I just searched at ebay.ph)

They're originally for HP's I think, and the seller didn't say how thick it would be.

I also found thermal pads of 1mm and 2.5mm thick... hope that helps.

EDIT: It seems the seller of the thermal pads have pads from 0.5 to *shock* 7mm. Just 3.2w/mK, though

EDIT 2: Seems he has a lot of different thicknesses of the copper shim--I sent him a question already.

 

why are those values doubled inside and does anyone know if i can undervolt it within its downclock modes?

Which tools do you use to test it's new vCore prior Bios Moding/Flashing?
Just set it and look if it works?
If i don't touch the bootclocks it should boot without any error right?

which numbers can be modified? Bootclock is 01 and won't be touched therefore.

I wouldn't ask if there wheren't 15! clocktabs and now i am a bit overstrained

 

My BIOS mod is linked to this thread somewhere, and the instructions for overclocking are he as well. Try the first page of the thread.

 

Any hope of mxm-II for mobility hd 5xxx series? Deskop 5870 made one hell of a good job.

 

Someone is driving in the fast lane Wait a little and we'll see, I seriously doubt it though. Acer already show us that MXM 3.0 is the way to go with 8935G and 5935G. If anyone dares to make MXM II HD5xxx, this is MSI. As we can see, they still support the older MXM standard in their relatively contemporary EX625 and GX623. Either way, it wont be sooner than Q1/Q2 2010.

 

Guys, seems like the gpu upgrade fury left us snif. We have to face the reality now, mxm II is DEAD !!!

 

I got my HD 4650 replaced.

I overclocked it to 675/594 non undervoltet.
Seems to run fine so far.

idle is 45-46°C, Furmark peaks at 90°C and 3Dmark06 at 77°C. All temps are NON undevoltet.

Seems like copper really does a good job. I used two 0,3mm sheets on top of each other interfaced with AC MX-2. So a 0,6-0,7mm sheet would surely give another few degrees improvement. But i´m happy with my temps by now.

http://img2.imageshack.us/img2/2346/windows7x64hd4650675594.jpg

Undervoltet to 1.0v it gives me 80°C max on furmark and about 70°C in 3dmark06. Could not overclock higher than 610/600. But it gives me 5939 3Dmarks, thats sufficient for me.

 

Did you get your 4650 at
http://www.ipc-computer.eu/it-pi-n-...r_Acer_Aspire_6930G_944G32BN-pId-2033407.html
?
it keeps showing out of stock.
i can't find other places to buy it.

 

Hey hey,

Brilliant thread guys

Looking at replacing the Geforce 8600M GS in my 5920g and (assuming I can still get my hands on one) i'll soon be sporting a HD4650.

Just a couple of questions (you knew they were commind hehe)

1. Any more live links for the HD4650? I see the previously mentioned link no longer works

2. This all seems like a relatively straight forward mod. Easily accomplished by relatively competant individual (see meddlesome fool)?

Cheers guys and err, sorry to bump a old thread but it's a gooden!

 

Hi

I'm watching this thread for quite a long now. And I am really impressed about this good news. I think I'm also going to buy a ATI Radeon HD 4650 for my 5920G. So I have some questions. And sorry about my poor English ... I'm from Austria. xD

Have anyone already tested the HDMI-Output with the HD4650?
Because this would be very important for me.

@ Classic77: The modded vbios for the HD4650 you uploaded, is this already the version with the changed clocks and is it undervolted?
Would be very helpful to know.

Please can anybody help me?

@ them who already bought a HD4650: Did you bought the VG.M9606.006 or the VG.M9606.005?

 

The vBIOS features the fan mod and undervolt. No clock changes though, I do those software.

 

Guys I'm back I say ATI Mobility Radeon HD5650 or GTS 350M is coming wait for 1 month then we can see whether any of them mxm-II, i don't think nvidia will be compatible but I have hope from hd 5650.
Acer Aspire 5940G has , Core i7 720QM and mid-range Mobility Radeon HD4650 graphic card. Any card fits on it will be possible for 5920 or 6930g.



http://twisted-reviews.com/acer-asp...st-notebooks-with-ati-mobility-radeon-hd5650/

 

I wouldn't keep my toes on it, though. The 5940G features a new chipset, and thus, a new layout, so it's highly likely that the MXM port, if ever it has one at all, would be an MXM 3.0 one, since it's on Acer's next-gen laptops.

Like triturbo said, we'd have better luck watching out for MSI laptops with MXM 2.1's instead.
