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

I recieved my 4650 today, and just put it into my 5920g.

The core of the module was about 1mm short of contact with the heatsink, and I was therefore getting temp readings of 110+ when running benchmarks for even a few seconds. I have applied a copper mod and the hottest I've read since is 95C (5C higher than my 8600m GT).

The copper mod I did was just a penny put through one of those penny squishing tourist novelty machines. I cut it to the size of the core an sandwiched it between the processor and heatsink. Canadian pennies are actually made of steel though and only copper plated so this really isn't a copper mod, just my temporary solution until I get my hands on a copper sheet.

***Update (July 19)***

I just hack-sawed away at an old aluminum heatsink for about 30 minutes, and from it took a perfectly sized aluminum fin which is now interfacing between the GPU and heatsink. My temps have fallen from 95C while gaming to less than 82C.

I don't think I'm even going to bother to get copper anymore.

***Update (July 22)***

I have done a vBIOS mod on my new card to change the fan settings, since ATItool doesn't seem to work as far as modifying fan settings goes. The trigger temp for 100% fan speed was 105C (!) by default. I changed it to 90C. (The temp vs fan speed profile is linear, so reducing the max speed trigger temp increases the fan speed proportionally at all tempuratures).

Anyway, the vBIOS flash went well using the standard tools. (Radeon BIOS Editor, ATi Winflash)

***Update (July 23)***

I have successfully undervolted my 4650 to 1V down from 1.1V at high performance. I LOVE the radeon BIOS editor, as you can undervolt only the performance settings and not the boot settings! The advantage to this is that its possible to tamper with voltage settings without having to worry about your card not booting up!

The undervolt has cut my temps another 7C (with overclock!). This alone is enough reason to stick with radeon as apposed to nVidia, since I was never able to successfully volt-mod my 8600m GT!

***Update (August 23)***

I think I've been running my 4650 for about 4 weeks now, and no compaints. Recently I played Dawn of War 2, a game that often dropped below 10FPS on low settings with my 8600m GT. I run it now on medium and never hit below 30, a MASSIVE improvement.

Also, as has been discussed later in this thread, the 4650 benches much better in 3dMark Vantage than '06, which is to be expected since it is optimized for DX10. I would definately suggest this upgrade for anybody running an 8600m GT or lower.

Here are some benchmarks:

 

how hot is it running, download everest, or speedfan to find out.

your too hot might not be as hot as you think.

 

Yup yup, just try to keep it under 93c. My 5920g died 4months ago after 10months of not so much use :/

 

Wouldn't you still be under warranty then?

 

Does it give the 30 second boot message?

 

They didnt want even to diagnose my lappy! Coz I live in Banana country.

I've been caught in the middle of missunderstanding between Acer and our official service. They lost licence to be an official partner and service due lame servicing but they needed to keep servicing all broken laptops till april 1st on their expense as punishment... But as it goes, they were ing up everybody who brought lappy in that period, me included... So probably I'll go to the home of that fat ugly servicer who took my lappy for diagnose and make him pay my dues! He threw 1200e down the ing toilet!

Update: and after that, i went to other service, they took my lappy for diagnostic and they never returned to me! I cant fing the guy who took my lappy! He stole it from me and ing dissapeared from the face of the earth! Cant find him for 3 and a half months... Banana Country


Sry for the offtopic :/

Bad karma?

 

What? Thats so wrong did you file a report with the police?

 

Umm, shop where I bought my laptop lost my receit and time and date when I bought my lappy... Misteriously... :s
So I don't have a valid proof that I even HAD laptop... exept a box of it :/

Mega bad karma...

 

wow that sucks. Sounds like an inside job for the store LOL.

ON the bright side you can get a new notebook now

 

Yup, but not that class less money, weaker lappy... For 500-600euros i can get pretty decent lappy somewhere in europe or usa, but here... Not even with nvidia 9200 and good c2d

 

What do you know about that? I got one of those messages a while back when I tried a 9600gt on my laptop.

 

Anyway, its running at about 105 degrees. Im about to do a copper mod.

 

Update posted; check post 1.

 

This is great news for 5920g owners or any other laptops that can take the ati 4650 mobile. Is the benchmark scores from overclock?, if not what are the standard clockspeed bench.
Nevertheless, it boosts the performance of the laptop which saves money from buying a new laptop, I'd totally get it to replace the nvidia 8600m gt in a heart beat. AMD/ATI sure is pushing hard to win against nVidia with the 4650/4670, with this they are certainly a step in the right direction!
All they have to do is sell it on retail!... lol

 

Nice to see that everything is up and running. Have you tried to clock that thing I still searching for MSI's HD4670 part number

 

Awesome news! If this is the case, then 5935g as well as 6935g should be able to take the upgrade then.

What are the temps after a run of furmark? BTW, since there was a tiny gap, wouldn't using a thermal pad be more effective? A method for those who don't know the copper mod.

 

The copper mod I did was just a penny put through one of those penny squishing tourist novelty machines. I cut it to the size of the core an sandwiched it between the processor and heatsink. Canadian pennies are actually made of steel though and only copper plated so this really isn't a copper mod, just my temporary solution until I get my hands on a copper sheet.

Still it took my heat down from 110C to about 85C

 

Nice job!!

 

Highly inventive "copper" mod, classic77, and congrats on the successful upgrade.
(was your 8600M GT OC'd? My 9500M GS wasn't capable of hitting 3900 3DMarks on stock clocks!)

 

Nice mod, glad to see that it works for you!

Just try to get some copper ASAP.

 

How much did you pay for the MXM card?

 

237 USD, it was ordered from this site: http://www.notebook-doctor.com/it-pi-n-Acer_VG_M9606_005_VGA_BD_M96_1GB_DDR2_500MHZ-pId-1881718.html

which is a repair site, so I had to tell them that I owned a 6930g 844G100MN and need a replacement 4650, otherwise they wont sell to you.

 

Ok , thanks for the info!!! +rep

Im glad it works fine for you!

 

Heyy great news on the graphics card upgrade glad to hear it worked .. you took a big gamble and it paid off fair play to ya .. just wondering will this work on my acer 9920g ... it has 2.4 t7700 .. 8600gt 512 chip .. similar to 5920g ?

Any help is appreciated .
Thanks jon

 

The two models are indeed similar. I'm hesitant to say it's a guaranteed upgrade, but close.

 

To give more info I got the 9600m GT for my notebook and since its not recognised I get the same issues with having to modify the bios and getting no monitor outputs.

So that's why I ask since if your machine accepts it ok (no 30 second pause at the start) mine might.

 

This is why I didn't hold out for the DDR3 version. I was worried that DDR3 might not be as compatible...

 

Urmm... Maybe thats why I got the 30 secs problem. Pic at this page:

I would like to have an HD4650 hehhee

 

Nice one Congratulation to your successful swap.

Btw. do the memory chips fit to the cooler ? They seemed to be a flipped and moved in comparison to 8600m GT.

And what are your Idle temps ?


Greetz,

 

classic77 - Have you tried HDMI output, is it working properly?

 

Right I have ordered one for my 5520g I'll let you know how I get on.

The worst case is I sell it at cost to some 5920g owner on here

 

Well, if I don't find the MSI's HD4670 part number and after that, a place from where I can buy one in the near month, count me interested

 

Got to go to work (BestBuy) but I have time to say, no, I haven't tried the HDMI as of yet. Also the pads fit the memory only because the pads were way bigger than the memory modules in both cards...they are more than covered.

Oh, and congrats Meaker!

 

@ classic77

ah okay thnx

which part did you order ?

what are your idle temps btw. ?

 

@ Nuke 333:

My idle temps are about 60C. Keep in mind I don't have a copper mod (just an improvized steel one) so they shouldnt be that high.

My guess is if you had an 8600m GT or similarly sized card you will need something to interface the card with the heatsink on your laptop.

 

Yeah i noticed that my 8600m GT dropped by a remarkable amount in temperature and i only used alluminium from a floppydisk ca. 0,2mm thick. My idle temp lies at 58-59°C and in furmark 500secs 88°C Altough allu is way better than steel, maybe you should try to use that untill you get some copper. Cardslot shields are 0,5 -1mm thick and mostly alluminium.

Which Part did you order ? 005 or 006 ?

Argh i want that 4650 really bad

 

What is a cardslot shield? I have been looking all over for about 1mm of aluminum as I'm getting up to 95C now...does anybody know what the max operating temperature is for a 4650 or any other M96 GPUs?

 

Ehm... those ... plates? at the back of your desktop pc where no cards are put into your mobo.

Length and width of a finger ?! Dont know how to explain it better

 

I know what you mean now, I was thinking it was a part on a floppy disk for a second...

 

I wanted to use an american dime, they are 90% copper. 90% copper is only as good as steel though based on my research lol...I've yet to take any metallo-chem courses..

 

yeah i should have listened to my physics teacher I never believed that one learns for live not for school. Thats a german farmers proverb btw., dont know the proper english one.

http://en.wikipedia.org/wiki/Thermal_conductivity

nice list of thermaly conductive materials

 

When I was using thermal pad for the core of my HD3650 it hits 110ºC, without blue screens, or what so ever, but it's highly NOT recommended though Lower your clocks and make a copper mod as soon as possible

 

mhhya that might be wise ... has anyone tried to use those high performance 16 w/mk thermal pads from mxm-upgrade ?

 

I doubt they'd work better than copper.

 

hm i´m not sure ... on one hand you have a material that is all 16w/mk and on the other hand one that is like 400w/mk but with two gaps of 8w/mk.

Isn´t the weakest part always limiting performance ?

 

It doesn't work exactly like that with heat transfer...its more of an average I would guess.

 

Hey, I just ordered my 4650 after being inspired by your success . Did you ever try using a thermal pad or did you try out just thermal grease and then move on to the copper mod. I live in Japan and a couple of weeks ago I found some thermal pads with some outrageous heat transfer ratings (they had 10w/mk, 20w/mk and my jaw dropped when I saw 30w/mk) . I was just wondering if the gap between your gpu and heatsink were due to the thermal pad not being thick enough or if you didn't go for a thermal pad in the first place. I was thinking of picking one up but don't want to waste the $15 if it's not going to be thick enough to fill the gap. Also which drivers did you use when you set it up? Did you use the Acer drivers for the 6930g or were you able to use the standard catalyst drivers for the desktop version of the 4650?

 

standard catalyst. Acer drivers are terrible...

There was no pad at all. Im not sure how a pad would work...maybe well if it was a 30...

Here is the site for installing the catalyst drivers. (Just follow the same instructions except tyoe 4650 instead of 4850.

http://rupp3r.free.fr/gt725/tutodriveren.htm

 

hm maybe you´re right, my physics knowledge is very limited

I´m remembering one thing i read recently. The thinner a material and the more pressure it is exposed to, the thermal resistance would decrease rapidly and thus increasing thermal conductivity.

So a 8w/mk MX-2 would become a 50w/mk one if thin enough and with high pressure i guess.

@wolfman
30w/mk pads `?? do you know their producer or where to buy ?

 

The pads I found were in a computer parts store in Nagoya, Japan. I don't remember what brand they were. I'll be heading back in a week or two to pick one up and I'll let you know. I'll take some pictures so you guys don't think I'm on crack ! I was thinking of picking up a couple and cutting them up into smaller pieces to replace the ones on the memory chips but now I figure I'll also try one out on the gpu as well. I just ordered the 4650 2 days ago so I'm guessing it won't get here for a week or two. I'll let you guys know what kind of temps I get.
