8800GTS, what is memory thermal pad thickness?

Planning to swap the stock GPU grease and pads for something better...

so I need to order the pads for the memory chips on my 8800GTS? (or can I reuse them?)

any idea how thick the pads are supposed to be?

The pads on there now are just white sticky pads that's obviously too large for the chips

i just reused the pads for the memory that are on there and applied some as5 instead of the crap it comes with on the GPU
