Copper shimming on gtx 675m + p170em, sizes?

Hey has anyone shimmed the gpu gtx 67m on a p170em.
What size shims did you use?
What thermal paste? (i have left over as5 but i heard ICD7 is better for memroy chips becuase it flows less but may not matter since Im shimming)

Id like to do everything I can for this card since my first one lated me 1.5 years on a stock machine zzzz stock clocks

Im asking now so i have less downtime and can order it now but if I have to wait for the new card to get there so be it.

 

Depends on your heatsink, it would need physical checking of the contact pattern to see if it was needed.

 

You post so much but every single one of your posts are useless, I wasn't going to say anything but its getting absurd.
for example this post, the post about a guy asking about a graphics card upgrade and you point out its the same card blah blah but you dont even help the guy stop spamming, someone else asked a question and you ragged on them and didn't even answer their question!

 

Well you see Rudekid95, it depends on your heatsink. You'd have to physically check the contact pattern to see if it was needed. Hope that helps.

 

I'm sorry you feel frustrated by the answer runeknight, I know what it's like with new hardware on the way. You want to get everything perfect immediately. However much like every chip overclocks differently, every heatsink is manufactured differently (same goes for the brackets). If your heatsink is spot on and has a good contact pattern then the pressure is spot on and the addition of a shim adds another two thermal transfer planes and will hurt performance.

Shims were mostly for older machines where the manufacturer took less care on such things (old acer machines were notorious).

When you get the machine feel free to take pictures to get an opinion on if a shim would help (or maybe some other modification would do better).

Most of all remember to have fun with the machine though :thumbsup:

 

You have not seen his other posts ignorantfountain

 

Just a note, use thermal pads for the vrms and gpu memory, you might want to see if you can use thinner pads than the originals if you want to eek out as much as possible but paste does not really help and just gets messy.

If you still feel like something is still in need of clarification just let me know

 

here's a clarification for you
Thermal pads suck for heat transfer, copper + thermal paste wins any day. Please stop posting on thins you know nothing about

 

Thermal pads can't quite match thermal paste for very thin gaps it's true, but for larger ones a pad will perform better due to the pressure, even a 0.5mm pad is way thicker than a normal gap between a core and heatsink usually.

The memory certainly does not need the extra cooling (even when over volted as I have tested) and the VRMs will run fine with the thinnest pads possible when over volted too. My information comes as much from my engineering back ground as it does from practical experience, hence why I have some of (if not the fastest in memory bandwidth limited cases) notebook benchmarks in the world. I am simply passing on this experience.

Hopefully this information will help others if they come across this thread

 

Who the heck uses thermal paste if for example the gap is 0.5 and up to 1mm and greater between VRM or memroy chips and heatsink? :cry:

 

You may not have caught them in the benchmark threads etc so here is an example:
