I used radlinker to do that. I get some problems trying to run it at 327, like freezing, probaly from overheating. Lowered it to 325. You can run it up to 330 without artifacts, but it crashes after a while.

Just tried again, mem won't go higher then 290. Well can't have everything .the core clocks very nice See if the core can go some higher. The bar stopped @ 450 @ ATI Tray Tools, but you can raise that bar.

weird how some people can see higher memeory overclocks, while others see higher gpu overclocks.

Your core's higher thats why your memory speed can't be any higher. I tried having the core outragously high and leaving the memory speed stock. I hit around 470/216 and it crashed. If you balance out the core/memory, you can find a large performance boost. Otherwise its useless cause sometimes the higher core speed with a slow mem speed wouldn't be effective in giving you more fps.

I have noticed that you seem to get more of a boost fps wise when you up the mem speed to a certiant degree, so i think it would be more helpful to put more of your oc power in towards your mem rather than your core.

Wow Kakarot you got a real cool system... is your room temp below zero!
My CPU idles at around 25 with fans on!!! and thats with AS5.

My HDD idles 35.... and my GPU is over 50! but i'm going to try this head mod on the weekend and post my results.

Even with the core @ 297Mhz, the mem won't go higher then 290.

I just got my 128, and forget what i said before, it makes a huge difference! 2050 3d'05. and games run much nicer. so im happy

clocks at 432 344. seem to be stable.

i wonder how much difference when i get my 1.8 to pin

@James_2K Would you like to post your 3dmark05 comparison URL?

Amazin, you're right, it is more beneficial to clock the memory higher than the core. The memory in these cards is more of a bottleneck than the core processing power. Most of the new graphics cards have a much higher clocked memory for that specific purpose of trying to get rid of that bottleneck. If it helped with the memory(I haven't tried it yet) I would just slightly overclock the core, to like 350, and then just push the memory as far as it will go. Might even be better to leave the core stock and push the memory up as far as it will go. Then, push the core til it gets unstable and back it down a little. Most people do it the opposite way, but it really is better to get a higher memory overclock and a high core overclock.

Didnt have the 2050 uploaded, but its near enough

not too sure what the deal with the cpu score is. it fluctuates a lot, in the slow direction this time. didnt use to do that :S 3200-4000 mostly

Is anyone else not seeing any pictures at all? I looked at this thread last night at home, no pictures. Got to work, checked it again, no pictures. Am I the only one?

ok, i tried this mod. with one difference. i took the tape off. basically as you can see in the ops pics. the HS looks silver, this is actually the thermal pad. if you remove it all its copper underneath. so i just took the lot off. as for metal i used foil on the memory (couldnt be as thick for me as the sheets of metal. well i just rebooted and will post any results in a while. but def. take that silver crap off too

It seems though that not everyone is able to get as high in memory as they could. I can almost reach 330 mhz without artifacts with stock core speeds, but others cant even reach 300.

I also am kinda tired of trying to squeez all the performance out of this thing anyways, since the only games I run are at least 2 or 3 years old and run no problem at 1024/768 with everything maxed

I can't get my memory over 300Mhz without artifacts, but I haven't done the heat mod. My core speed it easy to get over 400Mhz, but it doesn't seem to make any difference in benchmarking.

I'm a little worried about Dell refusing my warranty if I go in there and remove the stock thermal pads and put As5 in there. Anyone have any experience with that? Should I wait til my warranty is up, or is it safe to go ahead and do it now?

Well to be safe, yes. but really they will never remove the heatsink from the card. they would just replace the whole thing. and probably throw away the old one.

I've just done this heat mod... along with applying AS5 to my CPU and it has made a world of difference.

Taking the GPU apart was dead easy, only 4 torx screws.

I couldnt find any metal thin enough to put over the mem so i used foil, which i folder into two. Also i removed the black tape and removed the old termal pad.

My GPU didnt already have any thermal pads over the mem, just bear metal which def wasn't touching the heat sink as the core was slightly higher.

My GPU now runs stable at 410/325 compared to 410/305.
GPU temps: idles at 41 compared to 50 before, max 55 compared to 67.

Here my new 3D mark http://service.futuremark.com/compare?3dm05=1731610

And here my temps with the fan off:

My room is actually warmer then any other room in my house, its strange. I did the mod in the morning, took about an hour (was doing it slowly) so I guess my room was like around.. 60 deg F? at most..

Well I think I might try and attempt to do this when I have time with foil. Only problem is I don't have access to a thermal compound such as AS5. Anyway I could do this without having to spend a dime? Like maybe just reuse any thermal compound already found on the card, or some random household product that I might happen to have that will let it work, or just put on the foil without having to add any thermal compound?
