Here’s my system AMD 2200XP Thourbred B 2003 week 25 512 mb PC3200 CL3.0 Asus A7V8X-X +LAN Volcano 9 fan At the moment I have got a core speed of 2100MHz with a multiplier of 12 X 175MHz/35 and voltage is 1.65V. Memory is running at 2.5 - 2 - 2 – 6. Things are very stale with these settings and temperatures are from 38C idle to 46C using the program toast even after running it for 24 hours. My problem is I still think it will go higher, (seeing as the CPU runs cooler than with AMD’s recommended settings) but it won’t no matter what I try. Even taking the FSB up 1 more MHz things get very unstable. I’ve tried taking the multiplier up, the voltage and messing with the memory timings but instability is too bad. I have read sometimes the limiting factor is the full speed L2 cache not handling the speed, and that there are progs that can change this down to ½ to a 1/3. Do you think taking the cache speed down would allow me to get higher speeds, or would I be getting into CPU killing zone? Any help appreciated.

I don't know anything about L2 cache. But I think you should lower the multi and raise the FSB. Your Vcore and memory timings show great potential for further OC.

I have tried that in the past without any success. But now I'm pretty sure its the cache speed that is stopping me from oc more as i went into the bios and disabled the L2 cache. Now the only limiting factor seems to be the temperature. Does anybody know of a program that can modify the cache speed as disabling it altogether does affect the performance allot.
