I got the dreaded stripes and tried the baking method and amazingly it worked. But it came back and I think it's because I used regular thermal paste on my vram instead of pads or thick paste.
I'm going to get the pads but looked everywhere and can't find if I need 1mm, 1.5mm, or 2mm.
Thanks!

This is what I’ve used Minus Pad Extreme
Fue útil esta respuesta?
thanks. from their site it says, "The minus pad extreme is available in size 120 x 20 mm and 100 x 100 mm with thicknesses of 0,5mm, 1mm, 1,5mm, 2mm, 3mm."
which size did you use?
@justin06pdx - I always dry fit and either use a gap gage or some strips of card stock to fill the space to gage the size needed. I mostly find this series uses a 1.0 or 1.5 depending on the board used.
Gotcha. Mine was the AMD Radeon HD 6750M (or 6770M) with 4 vram chips.
Trying to figure out which pad to get sent me down a long rabbit hole so I just ordered the K4/K5 Pro thermal paste that is used to replace gaps. Apparently it's not great for high end stuff but I'm on a 12 year old iMac used for basic office stuff so hoping it works fine as many reports say it does.

**Update**
I got the K4 and K5 paste and redid the whole thing properly. Unfortunately I still have the stripes.
**Question**
I wonder if I actually zapped the gpu.
**What happened**
On that first attempt it worked fine and I only booted it up and observed but after a short while (less than 1 hour) the stripes came back. I know I didn't apply enough paste (which was confirmed when I took it out).
On my second attempt I re-baked it, applied the proper amount of K4 to gpu and K5 to vram and still got the stripes.
**Next Steps**
1) Buy a used card and try a third time (I assume the risk is that a used card is also fried).
2) Re-bake my card again
3) Take it to Apple and expect them to charge me hundreds which I'm unwilling to pay for a 2011. But maybe it'll be less.
Any wisdom y'all have is appreciated!
