Seems my P5k-P is having some issues breaking 440+FSB. So far I've tried 3 different 2Gb kits of PC2 6400 RAM, Corsair XMS26400C4, Crucial Ballistix PC26400C4 (single sided) and Crucial Ballistix PC26400C4 older style double-sided w/ Micron chips.
All 3 sets did 435 and their respective voltages (2.1 Corsair, 2.2 Crucial) at 5-5-5-18 T2, orthos, prime, memtest stable 24hrs. Tried raising the FSB to 436-440Mhz and it won't even post, no beep, nothing. Tried raising voltage to 2.2 Corsair and 2.3 Crucial still no boot. Thought it might be an FSB hole so I tried 450,460 and 475 FSB and still, no POST.
Can this be PC6400 hitting their max OC? Because thats one hell of a coincidence that all 3 sets hit the exact same FSB wall. So I'm thinking its the MB.
BIOS Settings as follows:
Ai Overclock - Manual
CPU Ratio - Manual (6)
FSB Strap - 333
FSB Freq - 340
PCIE Freq - 101
DRAM Freq - 881
DRAM Cmd Rate - T2 (5-5-5-18) Rest are set to AUTO
DRAM Static Read Control - Enabled
Transaction Booster - Disabled
-- Relax Lvl (0)
Clock Over-Charge Mode - 0.80v
CPU Spread Spectrum - Disabled
PCED Spread Spectrum - Disabled
CPU Voltage - 1.4750
CPU vRef - 0.63x
CPU V Damper - Enabled
CPU PLL - 1.50
DRAM V- 2.1/2.2
FSB Term. Voltage - 1.50
NB Voltage - 1.55
NB Ref Voltage - 0.67x
SB Voltage - 1.05
Anyone got any ideas or suggestions? Could be a dud board?
