netomx 10 Posted July 7, 2014 Hello friends! I have upgraded my brother's R3 to a GTX770m, and the old HD6970m, I am trying to install it to a friend with a R2. I don't know what I am doing wrong, I just can't. The GPU overheats (88C) and shuts down. I have used new diamond thermal paste, I have used new thermal pads, cutted perfectly for the RAM only. What am I missing? Thanks friends! Quote Share this post Link to post Share on other sites
Jinx1337 11 Posted July 7, 2014 What thermal pads (thickness, type) are you using? What thickness in what places exactly?What thermal paste? Quote Share this post Link to post Share on other sites
Nospheratu 275 Posted July 8, 2014 If I remember correctly the Dell 6970M's did not have auto fan control in the R2. You would have to use HWinfo's fan control to automate the GPU's fan's spinup according to GPU temps. Read more about it here. 1 Quote Share this post Link to post Share on other sites
netomx 10 Posted July 8, 2014 Diamond thermal paste. 0.5mm thermal pads. Fans are at 100% (4400rpm) manually using hwinfo- - - Updated - - -And I only placed it on the RAM Quote Share this post Link to post Share on other sites
netomx 10 Posted July 15, 2014 Update: I used a 0.019" aluminum shim between the GPU and the heatsink, and it mantained the temp in 75-80C, but I think I have damaged the GPU before that. After so many tries, it started to crash in 74-82 C when used, so it was useless, but worth sharing if anyone have heat problems. Tried the shim solution on a m15x (changed rom a 460M to a 660M) and the temp went to 38C with FurMark. Impressive at my point of view. Quote Share this post Link to post Share on other sites
Lizzo 14 Posted July 24, 2014 i used a copper coin between my gpu and my heatsink with thermal paste and it lowered my temps significantly (i was advised not to do it and it would not work) my temps were around 68-74C Quote Share this post Link to post Share on other sites
