Well it's been around >1yr since I packed away my DFI UT P35-T2R. But now I have dusted it off, flashed to 09/19/08 bios and plucked in my first of five E8600 Q820A599 cpus with 0537 serial number. Too lazy to do fresh WinXP install, so grabbed my DFI DK X48-T2RSB Plus WinXP install SATA drive and just used that

Haven't tried 32M stability, but started off with max FSB testing for 1M and cpuz validation. Ended up around 585FSB easy 1M, 590FSB finished but BSOD before I could save screenshot and 606FSB was best I could do for validation.

Using DFI MegaHalem air heatsink with 120x25mm Thermaltake 81cfm fan and Corsair AIRFLOW assisted PWM cooling
