I have got a 2000+ and am using a mobo that handles a 400 FSB. I have so far put the clock to 150, as it wouldnt boot at 160. I have put a Volcano 11+ on it, and put the multipier to 13. So it is running at 1.95Ghz. But I am wondering if it is better to get the clock speed higher, so that i can get better memory bandwidth etc. as i have PC3200 RAM, so at the moment it is being underclocked, well, either that or it is not performing well under the benchmarks. At the moment I am running the CPU at 32 degrees. This is a brandnew motherboard too, so I am pretty sure I cant have a cracked diode yet. I am using a thoroughbred core. here is a screen shot of my temps and CPU settings. (for some reason it now detects as a 2100+ when i changed the multiplier) Anyway, could someone suggest what I should do? Does changing the multiplier just put more stress on the CPU? How about dropping the mutiplier and try for a higher clock speed? Btw, i am using a albatron KX600S mobo.
