Guys,

I tried for a Super PI bench session today and for an unknown apparent reason i started off at 4545 MHz, as I get closer to 4.6 GHz runs start getting slower and eventually crash. Windows starts to get sluggish, the mouse stutters as it moves and then crashes and I get sometimes a "FF" on the LCD of the board. My best super pi previously was at 4734 Mhz so I know the CPU has more left in it for super pi. I noticed that the other day when I ran some 3dmarks I had an issue at close to 4.6 GHz too that's why I ran them lower at 4529 MHz. This all really started since I installed XP 32 bit, previously it was Windows 7 64 Bit.

If i was to reinstall or change the OS and the issue is not solved, what do you guys think it can be? Something degrading/failing, or just for some apparent reason a need of tweaking???
