I read the archives in Google on this subject, and was curious to get K6-2 450 (AHX and 2.4v) running on this mobo then flashed it to latest bios 626CC15 and since that the PA-2011's lowest voltage is 2.8 so I left this voltage settings jumperless (all open) and after 4 hrs of playing around those fsb and mupliter jumpers until I got 450mhz out of this setting-2x75 (K62 & 3 sees 2x as 6x, and Sandra reports it 6x75= 450mhz) ! then searched for couple of hours to find programs that CAN read & monitor cpu's voltage . Sandra and AIDA32 can't! Neither MBM, too. So how do I KNOW whats voltage the cpu is enjoying or suffering?? Thanks
