I've recently purchased an AthlonXP 1600+ and an Alpha PAL8045U heatsink, and am considering overclocking it. Considering how successful previous AMD chips overclocked, I was quite enthusiastic about getting a bit more speed for my money. After reading some articles online I began to realize that the process had become more difficult with the new AthlonXP's. I read a few articles online (see links listed above) and began searching online for the materials that would be required, when I remembered that my Alpha heatsink came with some Thermal Grease (Thermal Grease YG6260-5 to be exact). Thinking that I could just use this as the silicon paste I did a little research online and found this site
http://www.tweakmax.com/html/silver/silver-1.cfm that seems to state that this thermal grease is indeed silicon/zinc based. Now this is where my question lies. The article states that there could possibly be enough zinc in the thermal grease to conduct electricity. Can I save myself some money and use this stuff to fill the L1 gaps? Or should I buy a silicon paste without any zinc in it? If so, any recommendations where I could get some? As for the conductive paste, could I just use some Artic Silver II that I have lying around? Someone told me that it is non-conductive - thus would not be effective in connecting the L1 bridges.
Is it worth going through all this trouble? Has anyone been able to do it successfully? If so, how did you do it; how hard was it?
