Hello guys,

I've been following this thread for some time now, since I own a P5Q Deluxe (BIOS 1102 now).
Thanks a lot to all contributing/posting members, you've certainly teached me a lot.
I came from a P5K Premium, so this is a whole new world for me.

I know there is no rule of thumb but does anybody know what probable maximum FSB is achievable on this motherboard with a QX9650?
I mean for 24/7 usage.
My main activity is Folding (12-14 hours a day) and some gaming too.

My actual settings (12h Prime95 Blend stable):
AI Overclock tuner: MANUAL
CPU Ratio Setting: 9
FSB Frequency: 444
FSB Strap to North Bridge: AUTO
PCI-E Frequency: 103
DRAM Frequency: DDR2-1066
DRAM CLK Skew on Channel A1: AUTO
DRAM CLK Skew on Channel A2: AUTO
DRAM CLK Skew on Channel B1: AUTO
DRAM CLK Skew on Channel B2: AUTO
DRAM Timing Control: MANUAL

If I try going up to FSB445 for example, and RAM at 1070MHz, Prime Blend fails after aprox. 50 minutes on one core, with a rounding error.
Prime Small FFT's works fine for more than 6 hours, so I suppose that I don't have any CPU OC-related problems.
It's curious that even at FSB450, F@H SMP Client 5.92beta corrupts no working units, but Prime Blend fails very quickly...
My memory doesn't seem to overclock a single MHz, and that really annoys me.

Any suggestions on this would be deeply appreciated.

Take care,
Miguel
