ok since i had a couple hours of free time, i decided to reapply the thermal paste on the card. I used the oh so glorious, AS 5 on the gpu as thin as possible using a razor. (i cleaned the previous thermal paste using the arctic cleaning kit). Im getting higher temperature readings than the last time.Arctic Silver recommends just placing a small amount on larger areas (current GPUs would fall into this category) and not the super thin overall applied approach.

ive got problems with my XFX 6800GT, ive already posted in another forum for help, so its easiest if i just give you the link, so i dont have to write an essay, i would appreciate all help you can give me, its a rev 2 btw

Well, it seems like the guys there have covered most of what I would have thought of. Is it possible that your AGP fast writes setting could have changed? Maybe try checking that as it would explain your much lower score now. Also, if you can get some more thermal compound handy and can check your GPU imprint on the NV 5 that would help too. My guess is that you're not getting optimal GPU contact. It may have at first just because the AS5 hadn't settled in yet. Once it had a few hours to do so then more of a gap may have occurred.

i actually have a pci express 6800GT, rather than an agp one

would u suggest taking off the cooler, and maybe re applying the thermal compound but with a little bit more?

Ah sorry I overlooked that little detail. :)

Yes that is what I would suggest. GPUs can handle a bit more thermal compound than CPUs regarding the risk of insulatoin IMO. The main goal for you should be to determine if you're getting good contact or not. Don't put a very thick layer on but maybe just one more layer's worth of what you applied originally. Then, just screw it back down...then unscrew it and remove it and see what kind of imprint you get on the cooler...it should be a uniform imprint from the GPU.

ok well i took the cooler off, heres the pics of the hs and graphics card

ive re applied thermal compound, its still not working as it should

right well i refitted it again, with the last attepmt i think i had better contact than before, but still not very good, i put loads on this time, to make sure the centre of the gpu was getting contact, still crap tho,

1 thing tho, when i do the detect optimal frequency thing, it used to be at 426 / 1.15 i think, or 428, but now it goes to 430 / 1.16, this a sign that the cooling is getting better?

That looks really odd. By those pics it looks like there is no contact being made between the NV5 and the center (most important) area of your GPU core. Am I seeing that correctly? If so....that would definitely explain your temperature issues. I can't imagine what would be causing you to get good contact around the edge of your GPU but not the center.

Looks like the casting of the sink contact surfaces were never machined flat and left concave...odd? Definitely insufficient contact on the core of the gpu.

Clay

That is what it looks like but strange that it would be machined incorrectly so that the lowest spot of the concave is exactly above the GPU. Sure the GPU surface is flat...almost seems like it may not be though.

good news sorta, after trying it right after i re applied compound, i was getting low scores and crap performance

anyway i left it about 1hr 30mins, and its working amazing, it did this on wednesday when i first re applyed compound, it was crap then, left it for an hour worked great next day back to crap, so il have 2 see if its working tomorrow hope so

btw i turned the comp off for 1hr 30mins

OMG!!!! i just restarted and its gone back to **** performance, i checked the temps before i restarted, was at like 56, its at that when i booted back, wot the hell is up, temps seem to be the same, ive done nothing else cept restart, yet its gone crap again!!!

Hey

I know, there are plenty of nv5 threads, but i would like to open another.

So, I finally decided today to get a silencer for my 6800u (msi).

I've installed it (it took me 2 hours, checking it again and again if it fits), right now i _think_ it fits, but i'm not sure. I held it up against light sources in different angles, and i can't see through any part of it... so, I think it has good contact. I checked even by removing and replacing it, and it seems like the gpu has good contact.

For the rams I am using the blue thermal pads, because if i remove them, then the gpu is the only thing what has contact with the copper.

BUT i am getting very bad results.

closed case, card OC-d to 435/1250.

idle: 58 core / 43 ambient
3d: 85 core / 68 ambient

with the stock cooler it was 56/41 and 75/53.

What did i do wrong? I am very disappointed right now.

Did you put AS5 on the GPU?

noeX

03-23-05, 04:01 PM

yes

Clay

Can you provide a picture of your GPU imprint on the NV5? I know you've checked contact pretty well it seems but it would still help to see what you are seeing. It really sounds like a case of poor contact. How much AS5 did you apply? Possibly applied too much?

noeX

03-23-05, 04:09 PM

I don't have a digital camera. ;/

I didnt applied to much, it's about enuff thin.

Clay

Ok. Are the screws tightened down really well? You don't want to overtighten but you do want it about as tight as you can get it without really forcing it.

noeX

03-23-05, 04:12 PM

i tightened them as much as i could, even with a tool.

I'm just back from the other room, when I was working on NV5 for hours, modifying memory pads. I used a file for a some time and then lost my patience and started to use a dremel and every tool that could be usefull and wanted to ask you this:

IS IT WORTH IT?

I have Albatron 6800GT with very high memory modules :(
It is worth it to some and not to others. So it just depends on the person. I found it to be worthwhile in the end as my temps are substantially cooler and I cannot hear the NV5 over my other case fans and drives.

Should it be less of a hassle? Yes. Can I appreciate how it must be difficult for Arctic Cooling's design to cover varying height memory modules and a GPU? Yes.

Ok, so does anyone have any idea regarding my problem?

Sorry, I'm stumped as it seems that you've ruled out every possible potential cause. Have you contacted the place you purchased it from or ARtic Cooling or Scythe USA for any ideas?

FINALLY got this B**ch .....

I'm getting very good contact on GPU, but now some memory modules are not.

However I think I will fill some gaps with thermal paste. Is this thermal paste that is provided any good? I dont have anything better, just some paste that I own from years back, wich I'm using to see if the NV5 fits on card.

I'ts pretty good using the dremel, just be carefull about the screws.
