Replace Thermal Pads on your 980M

I had issues with overclocking the memory on the 980M, limit was about +150. Right now I'm running it at +395. The only explanation I can come up with is that I replaced the thermal pads. The 4GB of ram on the backside of the GTX 980M uses horrifically bad thermal pads.

I believe my OC and performance issue with ram was thermal, and we all know that is hard to monitor since GPU sensors do not monitor ram temps.

Good luck.

 

sounds good although ive only replaced the pads on the upper side of the vRAM im still managing up to +500 Mhz max. / +460 Mhz with Core OC. couldve been a misalignment of your backside pads, but glad u got it sorted

 

What pads did you use @Zymphad? I do plan want hope to get 980Ms someday, and it would be quite good to sort of.. gather everything I need. I already have a bucket list of things in a text file on my PC.

 

Bump for this. Would eventually like to upgrade my 7970m to a 980m for my p170em, and this info would be helpful.

 

I used the Phobya stuff cause it was cheap, and it seems to be working fine. Got that and the Phobya Nanogrease Extreme here:

Same company sells what I would probably get instead if did over, the Fujipoly

I placed the thermal pads as the picture above with fujipoly, cut them into pieces over each ram.

 

Hmm it's not on that page, but use the search function, I bought the Phobya XT Pad 7w/k.

 

is there any temp difference? Wonder if using little copper cut outs with the pads would be better? anyone ever do that?

Also what about
Indigo Xtreme Engineered Thermal Interface do these work well? Does anyone have experience with this, can it even be used on a laptop? If what they state is true I don't see why more people wouldn't be using this since it looks alot easier to install and is suppose to be great, I am new to reduceing temps as I have never really owned a laptop that I ever had any reason to try and get the temps down, so please anyone feel free to educate me some more thats why I am here and posting thanks guys

 

With pads, the golden rule is get the right thickness, as thin as possible that still gives contact, follow that and you are golden.

 

I said you can't monitor ram thermals. No way to tell except when your overclock fails, likely from either not enough voltage or thermal. For me it seemed to be a thermal issue.

Indigo Extreme only works if it spreads well. Since laptops have heatsinks hanging upside down, I have no idea if it will spread well.

Also Indigo and other liquid metal TIM fuse to the copper heatsinks. It's a mess. After I tried using Coollaboratory's Liquid Metal Ultra I had to use wet sandpaper to get it off and then spend 40 minutes relapping it. I would not recommend using liquid metal unless it's between the die and IHS of an Intel CPU.

 

@n=1 supposedly recommends mild acids to remove any residual stains left by CLU on the copper heatsinks havent tried that yet though

Wouldn't acid possibly leave the copper more porous requiring lapping or more attention to a paste job?

 

Mild hydrochloric (muriatic) acid is fine. Just don't use concentrated sulfuric acid, and avoid nitric acid at all costs.

Although nitric acid would work wonders if one wanted to get that CLU stain off the heatsink...

 

I just increased the pressure on my GPU heatsinks and CLU went from being on par with ICD to offering a benefit, I can see contact has improved a lot. The layer is just so thin you have to be so careful.

 

How did you increase contact pressure?

 

I added washers to the x-bracket, this does increase stress on the arms of the heatsink so great care needs to be taken.
