MSI's HD4670 is running in my Acer 5920G

When i start laptop with my dead 4670 , core is not cold. it is warm. Maybe is not dead

 

If it doesn't output picture it's more or less dead. It could be fixable, hence I'd recommend to get it to repair shop.

 

Even if the core is warm(thus getting power), a gpu is an advanced piece of electronics that require a lot of different components and correct voltages to each of them to operate correctly. For example, the power(1.5 volts for ddr3?) to the vram may have been cut off. Have a look at mxm 2.1 wiring diagram to find the power supply lines and trace them to the nearest components on the card and test them with a multimeter against the proper values. If you are uncertain about this, take it to some qualified professionals since most repair shops could make matters worse on such obscure situations. I would guess the goner is the DC-DC transformer (the little gray box on the bottom right side of the card) and could also be the transistor next to it. Just my 2 cents, good luck on getting it to work.

 

alright a i know some stuff about this. it may need a reflow or reball. in my case it was cracked core which IS fixable if you install a GPU core via reball, i found new core that cam pre re balled. there is a possibility he could have it fixed but, honestly it's not that much faster than GT 240m and runs hotter.

EDIT: shop on ebay for electronics repair and re balling services.

 

Hi all guys, again in never ending topic with 5920g modding
Still after 7 years owning (7th) Acer Aspire 5920G. What a great machine after all the years, it can offer much more than new laptops these days. Still I think about more upgrade...and more upgrade...and SUDENLY ....

!!!!! I will have Ati mobility radeon HD4670 mxm-II 512MB GDDR3 !!!!!

I had to buy whole broken MSI gx623, the guy didnt want to sell it separetly, but will be better for doing bios moding in original laptop.

As I know it heats like hell, I inspired a little bit of Triturbo mod, and this time I am working on better cooling. Not so much hardcore. But we will see the improvments.

As long as I will have some results, I will post here some photos

 

That's great to hear, good luck! As for the cooling mod, I think that it would be sufficient to swap-in an MSI GT627 fan (it requires a bit of trimming), or probably lenovo T500 fan (haven't tried it and I think it requires buying the whole heat-sink assembly). The fans alone would be more efficient than anything else, and are like 3 to 4 hour job max. Of course the fan + additional modding would gain some more, but if you don't want to go big and spend A LOT of time and money, the fan upgrade would be sufficient.

 

Yeah, I allready have fan from MSI GX630, I did some test of airflow and compared with the original. But it has plastic holding and it loses on cooling capacity, so the fan is going to be mounted od copper deck from bottom. Also graphic part of radiator is going to have copper radiator.

If you give me email i can send you photo of my work.
And gues what. I havent spent a single € on this mod till now. Just a 2 days of cutting a thinking how to make it right

 

Amazing this little laptop is still running. I remember Triturbo when you and I used to compete my Asus C90P vs your 5920g. Well yours far outlasted mine!! Happy times indeed :thumbsup:

How does the 4670 hold up these days in games? I remember mine used to do well in Crysis 2 max settings at lower resolutions with the core OCed to 830mhz! That was years ago though!

 

What did you used to put new copper heatsinks together with heatpipe and metal parts Triturbo?
I was thinking a pewter would be good, but friend told me it has bad thermal conductivity.
A there is a problem that pewter hardens in second after heating and therfore it would be hard to put it together on all perimeter of heatsink.

Anyway what do you think about "Coollaboratory Liguid Ultra" thermal paste. ? Heard that there is 5-8 degree drop from MX-2/MX4

 

Why external? You can cut the plastic and stick it to the heat-sink with some Kapton or copper tape. This way you'll retain portability. This is how I did it. Cut the surrounding plastic, then cut the rest in the shape of the hole in our heat-sink (bottom view, since this is the correct way it has to spin), then stick it with copper tape. I'm currently running M17X-R4 GPU fan (11CFM) and while better it's A LOT noisier. So much that I think of switching back to the MSI fan.

Yeah, 6 years and counting, and this is 7 years (mid 2007) old model (I got it from a sale)

As of recent - Max Payne 3, Bioshock Infinite, TDU 2, L.A. Noire, all play smooth at medium settings I have some hopes for GTA V, if I haven't got another machine by then.

Arctic Silver Thermal Adhesive. You have like 5 minutes to put everything where you want it, and then leave it for a day to get really hard.

I'm afraid of this thing, you should be too It kinda worth the risk if you have all copper heat-sink, but ours have aluminum as well, and this thing eats it Seriously, even then you have to reapply it like at least once every 6 months or you risk the CPU to stick to the heat-sink... I haven't dig deeper, just from what I read here and there. Do your research and if you feel like it, go for it!

 

As I think of the cooling. The msi fan will give more airflow, but the air vent for graphic is very small, unless I would remove the Lan and vga port like you did. I have to transfer the heat somwhere else. Thats why I came to the idea of complete copper bottom with fan mounted.
It will give more heat capacity and I want to atatch it to the graphic heatpipe and main radiator so the heat will be common.
I gues it will help, but I can be wrong. Think is...I will not know until I try it


So would be better to use that arctic silver thermal adhesive instead of pewter?

 

Seems promising. You should make one for the top as well, with round opening though (like mine). What are you planing to put for the GPU? Well, to tell you the truth, cutting the LAN/modem probably makes some difference, but it's not the better exhaust than the bigger radiator I've put there

With pewter you probably mean solder? It's hard to do it with solder, given the fact that you are dealing with heat-sink (gets the heat away ). You would need blow-torch or something like that, but there's the risk of expanding the heat-pipes, which would render them useless. That's why I didn't want to risk, so I went with Thermal Adhesive.

 

Yop, there will be also at the top, again from MSI heatsink used. But have to do the bottom first also to know the high. Your gpu radiator is massive. Anyway great video with that meter heatpipe :thumbsup: For the GPU radiator i cut other original heatsink at half right after heatpipe on main radiator. I will need to solder or with that thermal adhesive put together 40 copper small plates Its ideal because the slope of it will aim the air to the vent.
and
I am in need of better tools, dont know how to make those holes for fan in copper plate. All my tools are too big or wrong shape.
I did some drilling today but thats only half work. I wanna have it proper so it could maximize its potential.
And I found out my fan probably broke down
I found the "pewter" in google translate so I mean solder, if that is to common word used

Here is what i found as adhesive, should be good i think.
http://www.tntrade.sk/arctic-alumina-aata-5g-premium-ceramic-thermal-epoxy_d13410.html

 

Thanks

Try to drill a hole and then pull it sideways in order to make the hole bigger, in the shape you want. Or get yourself mini-grinder (Dremel), it's not a miracle worker, so don't expect to do it on it's own

That's Alumina, I've also used it as well. Since I underestimated the amount I'll need for the project (I bought the Silver over eBay) and I didn't want to wait, I got Alumina locally (I couldn't find Silver). From what I've read the Silver is a bit better, but the Alumina would do just fine as well.

 

Love this laptop!! I hope you guys can figure out a way to put a compatible 4870 inside! I know it is MXM II type III so won't fit but it shouldn't stop you trying. I got a 4850 to "work" in my C90P haha. Although I had to partially destroy the cpu heatspreader so allow the card to fit!! Shame it only outputted to external monitor.

Please don't stop the modding! I have started doing so with the M15x and it brings back memories approaching it's 5th birthday.

 

Once I heard from people: "It's impossible tu upgrade laptop" what an uneducated people... a lot can be done. You just have to find a way to do it. Little work, some monay, and lot of googling

Anyway today I have finished grindering... happy that I am going to do some other things .. and have to order that thermal adhesive to continue. and tomorow its the D-day 4670 ariving
I will test it and compare on stock cooling with Nvidia 9600M GT to see the temp difference.

 

Even when we consider that there is literary no room (the cooling fan has to be sacrificed as well), there is no practical point, it's still a DX10.1 GPU. I've tried to get DX11, but no go - GT 240m to GT 550m and HD4650 to HD8850 My theory about the Quad-on-PM965 has been proven by brave ThinkPad modders, but for me it's pointless unless I got one of the GPUs working, which is not going to happen sadly. I gave-up. I'm saving for a new machine.

You made quite of a progress with this 15 incher Watch out, because I hope I'll get first gen i7 machine as well

If I got an euro for every time I've heard it, I would've crowd-funded my new machine

Good luck and keep us posted

 

Hey Guys, can you help with one thing?

I got that MSI wit ati card and I found that tere is Intel 512an wifi card (intel5100). I use Atheros AR928x. and I noticed that you use Intel 6300 triturbo.
Do you have any experience which one is better?
I was looking on the internet to compare but the experience is more reliable source.
Does Intel makes better wifi?

 

Honestly I can't tell. It's form chip-set to chip-set with either brand and I'm not familiar with either of those two. It's up to you to try it, but you'll need a bracket, or you can DIY something

 

Please do. The first gen i7's still have plenty of life left in them. I reckon mine could do 4ghz across all cores air cooled. I just need to bump 2x multi to get there. Easily said than done though.

Going to try 29x tonight so if successful I might just be 133mhz short!

 

How much you've bumped it (the voltage)? Whatever, burn this thing I want 4GHz!

 

So, You can count me as 5920g user with HD4670 fully working

But only on stock cooling and power saving mode. I am not going to push it to extreme until new cooling will be made.
But I am surprised of the temps. I gives less temp in idle than 9600M GT (and with no underclocking), probably because of 55nm instead of 65nm

Maybe you are going on newer machines these days, But god I love my 5920g, dont need any other laptop.

 

Welcome to the club

You are surprising me - calling HD4670 cool!!?! LOL I guess your thermal paste (on the 9600m) was old, because I know that it's pretty cool running GPU. Anyway, forget about the idle, check the load temps, this is where HD4670 shines in melting-metal-white

I sure love it too, otherwise I wouldn't have spend money for top-tier laptop upgrading this one It just shows its age, and the new games' requirements are way above what it can offer, sadly I'll keep it, that's for sure.

 

Yes you must. This is a machine whose story you must tell your kids about. haha

I wonder though. If you were to overvolt the 4670M some and completely overhaul the cooling you might be able to achieve 1000mhz on the core. The ram also you could overvolt and try for 40GB/s-45GB/s bandwidth lol

I remember even at extreme OC (800+mhz) my old 4670M only 55C. So with proper cooling in place it can be done.

Then you might be able to play decent settings at low resolutions once more.

Here we go: http://www.xtremesystems.org/forums/showthread.php?204687-4670-VGPU-MOD-anyone
Post 15 Yes it is desktop card but maybe there are many similarities. I was considering it before it died lol

 

It's a bit unusable to be honest. If I had higher res display, then yes. I've played recent games at pretty good settings with my current setup and the newest games require DX11 and quad core. There isn't really a point in pushing it more than I currently do. I'll probably check it to see if it works for us Thanks for the link!

 

Yeah that thermal paste on 9600 was kind of older, but even when it was new (5 months ago) i have never had 42 degrees in idle 45 was the average...and HD4670 can cool down to 40 degrees 9600 could cool down only to 43.. so yes its cooler

And I tryed a little older game which dont use graphic core so much and the temps vent to 80-90 degrees.
When the cooler will be finished. I will load it at max and maybe than I will think about overclocking a little bit.
Its very rare card. I dont want to destroy it. And that 9600M GT is going for sale.

And I realized. I had some other parts from 5920, but i swap hdd cpu ram and wifi from msi, buy a keyboard, use old 9600M GT and I have another fully functional 5920g

Does anybody wants to buy it ??

 

The CPU wont work, unless you pin-mod it (or if it's 800MHz FSB). Even then, it's only worth if it's X9100, since it'll be downclocked and the easy way to bump it back to its speed is if the multi is unlocked and use ThrottleStop. The harder - to solder a wire, so you can use SetFSB with any CPU.

Usually it's like this when you are into modding I have assembled a fully working one out of spare parts and I can built two more minus the displays and a few minor parts

 

What driver do you use for that mobility 4670?

I looked at device manager, and I have missing driver for "Atitooldevice" ... what I found on internet is that its definitely driver problem.
I used latest from AMD support for windows 8.1..... 13.1 version
And I also have problem when running flash player video on youtube. All HD video are lugging. non-HD video plays normally.

 

On W7 x64 and I'm using 13.9. This is the last one for the so-called legacy GPUs. Give it a try, it might install under W8.

 

13.9 didnt work for me. But 13.1 is running good on W8.

I Had a 3 weeks delay from my work on cooling. Had to wait for friend (blacksmith) to make copper really narrow.
Now I am putting together up cover for fan with gpu radioator (hard work to make all 40 small plates hold together , but with small steps it will be done) than I will put fan, and do some cosmetics.
Not so much work till finish. Can wait to see the improvements.


That grid is going to be mounted on plastic over, so the fan will have open vent nad it will provide a cover.
But I am still thinking, if there wont be much dust. Because the whole heatsink is going to be glued with that thermal adhesive.
Always wanted to do that grid
What you thinkg about that guys?

Also I did new transparent cover for motherboard under heatsink. Just visual upgrade

 

Good work so far. Yes, there will be dust. You might want to put DEMCiflex (the filter only, without the bezel) on the back-door/cover, since you'll glue the fan to the heat-sink. You'll get little to no dust inside, so no need to worry. I do have to clean the filters once every two months or so, though.

 

So my work is finished.... or not?

I have completed the cooling..


I have waited for MX-4, and today I fully lounched it.
I must say when the lappy is cold in morning, it cools more passively, until it reaches 45 degrees in graphic card... (15 minutes on idle)
But then, fan allways on, probably due to bios setting of fan control.
And I tryed a little gameplay. Stalker call of prypiat DX10 full graphic setting, performance is excelent as it was playable.. And after 5 minutes i checked temperatures.

procesor: around 50
Graphic card: !!!!! 113 degrees !!!!! and it shut down becouse of high temperatures


Either I completly messed up graphic part of cooling and it doesnt transfer the heat well...or Jesus that card is a HELL
A thought of some overclocking but...
I think I should do some underclocking at first.

 

From the second picture it doesn't seem that the fins are making full contact (if at all) with the heat-pipe. This is crucial for the heat-transfer. You might want to redo the GPU part. Stick them directly to the heat-pipe with as little glue as possible, and then put some adhesive on top with some additional cut fins (as it seems they are not tall enough). Other than that, pretty nice work

 

Yeah, I also think it has to be remade, probably did the mistake with a lot thermal adhesive there. They are touching heatpipe on 4-milimeter each to one half of heatpipe. I gues of doing complete new cooling as well because the potential of graphic heatpipe is not good. Probably I would have original cooling there with adding something, or copper block with with that fin to make full contact with heatpipe. And maybe I vould like to use new heatpipe from that msi GX cooling.
I would like to use also other fan as this is also noisy at normal behaviour. Thought of some Lenovo fan, probably Edge E530, they are not so loud on lenovo. Dont know about acer. And to do that to have possibility to open it and clean.
I dont have problem with dust so far. ( our house is clean at all) but for future time it will be some dust there.

 

Treat thermal glue like paste in how much you should use.

 

This machine is pretty awesome isn't it, Got mine since launch don't even remember how long exactly, it's about 6/7 years old isn't it? Just did a re-paste on mine.
What are everyone's temps btw? Want to see if I did a good job on the re-paste. I think I did good, I've never heard to fan stop spinning b4 lol.

Room Temp 20c

 

If those are your heavy-load temps, you did pretty good job

 

I got problem guys.

I have put the original cooling back to my 5920g with 4670. Everything is going well when I have it on power saver, Laptop working normally. Also the temps are good. But when I try a little play on power saving, games runs smoothly but after 5 minutes I get artifacts on screen. I was looking on the temperatures. With that upgraded cooling GPU hits 115 degrees and runs fine. With that original cooling GPU hits max 98 degrees but i gets me artifacts.

I moved back to Windows 7 with 13.9 driver I have clean instal, so no driver faults I think.
I have PSU Intertek AC190V4.74-S which is 90Watt adapter, maybe it because laptop needs more.
And I have never had that with windows 8 even with higher temperatures.

Do you have any idea what may cause that problem?

 

Overheating. Most likely your vRAM. Anything north of 90 is scary. You should think about undervolting it.

 

Undervolting did help to decrease temperatures but the artifacts still remains.

Just a few seconds of FurMark burn-in stress test, and the artifacts go on. Sometimes when I played the game and the artifacts went on. I pressed ESC do go to game menu, and the video got normal, sometimes it showed me BSOD.
I guess it happens under full graphic load, but in windows desktop it runs just fine.
Now the temps reached max 70 degreees which is good I think and again artifacts on screen...

I did checked my bios setting in case, default setings loaded. When I was in tha bios, fan went on top speed as the graphic is also at top frequencies when in bios, and the screen was OK.

So could it also be driver problem?

 

Which driver do you use? What do you use to cool the vRAM chips?

 

Problem solved
In fact it was a pretty stupid thing. The transistors or whatever is on graphic chip on sides were touching the copper plate between chip and heatsink. So i gave there the plastic cover like it use to be on chips. No more artifacts.
A think I am a little bit lucky. Maybe it could even destroy ma gpu if I didnt found out.
And what is more I undervolted it to 1,1V and overclocked gpu core to 700MHz ...and it runs just fine max temps around 93 with original cooling.

 

Good for you that you found out about it before something goes puff. At 1.1V you can go a bit more than 700, also the memory would be stable at 900. Enjoy your "new" machine

 

Thanks. Yeah I wanna try memory at 900Mhz ... and I am close to performance of my brothers 6650m when I compare it via windows experience or bandwiths in gpu-z

And Yes I enjoy it very much (also the weight when transporting) and I remember the time when I was deciding which laptop tu buy. Everybody was skeptic and refusing about Acer ... but i did not made a mistake
Its a memorable laptop and still offers me much more than others

 

So a brief info ... HD 4670 now running at 900Mhz memory but... suddenly I got 3 broken laptops, I pulled out their cooling, let my fantasy work and here are some informations about my new project:

4 heatpipes
3 independent radiators
2 fans
a lot of copper

ALL THAT IN MY 5920G

So you can gues how it will look like

More info and pics later

:hi2:

 

Good luck with your project. It's pretty space constrained, so I can't imagine how exactly you'll fit all of this inside, but I'm looking forward for the updates

 

How are your projects going on Triturbo?
are you doing 8740w?

I am currently starting that my cooling project for 5920. I had to wait for some free time. And now I am looking for metal pads and thermal paste. I got to "Inovation cooling diamond 7" do you know this paste? In comparison to MX-3 it should have few degrees less. So i am considering to try it.

do you think i could use these collaboratory liquid metal pads on graphic memory chips?

Coollaboratory Liquid MetalPad - the innovation of cooling for High-End sytems

and I an not certain, where could I get the black isolating plastic material, which is basically under 5920 heatsink on motherboard? do you know what exact material is it from? I would like to use it around that graphic chip and also around memory chips and use there a good metal pads. its great thick heat isolation and it doesnt melt from heat as my custom. They say it is possible to use it on aluminium heatsink also with no problems, so I will definitely use it in my new one, but i dont know if i can use it on memory chips. What you say?

 

Yeah, I'm all over 8740w as of now There's plenty of room for improvement will see how it goes.

ICD7 can scratch your CPU and GPU die when removing, so be careful. Others see improvement and like it very much. I tried it, there was slight improvement, but I didn't liked it. I'm using Gelid GC Extreme now, was using MX-4 before, pretty happy with it.

Don't have experience with it, and don't know how thick it is, it might not be thick enough for the RAM.

I don't remember what kind of material it is. Maybe graphene?

 

I have a bad news... my 4670 is dead...or the motherboard is.... and just a few days before finishing my cooling... what a sad day

I looked at the card and there is no sign of physical destroy so on card and so on motherboard. Diodes light blue and the graphic chip heats a lot but no screen so probably 4670 is dead...and I undervolted it and also reversed to stock clocks... :-(

 

Do you have another GPU to give it a try? You were overclocked on the stock cooling? Those things do burn if it's not taken care of. I've ran mine undervolted up until when I fixed the cooling. Even then I just tried to see the temps and undervolted once again since there is no performance to be gain that would be of benefit for modern games and I want my system as cool as possible.
