Are all Thermal Compounds for both CPU and GPU or are there different greases for the different items? I found a thermal compound that's good and cheap but I need it for both my CPU and GPU but in the description they only talk about the CPU and only gi examples with it. Is i then only for CPU or could I apply it to my GPU as well?

Eko... Check out this link. I'm referring to the pictures near the bottom..

http://translate.google.com/translate?hl=en&sl=zh-CN&u=http://www.wifi.com.cn/backup/2-wifi/linksys-wrt600n-v11-naked.html&ei=IikUSv67JOCEmQeyy4TnAw&sa=X&oi=translate&resnum=8&ct=result&prev=/search%3Fq%3Dwrt600n%2Bjtag%2Blocation%26hl%3Den%26sa%3DN%26start%3D10

I'm looking for the jtag connection points on a wrt600n. Looking at what you have found on the motorola device, I see a similar bank of smt resisters in the same location on the 600 as with the motorola.

I've been begging for a 600 brick to check it out but so far, no volunteers.

What do you think.. Can you get your hands on a 600?
