I went into the Bios and set AI Tuning to MANUAL, then I tried to change my E6600 CPU Frequency to 300MHz to test (from 266 default).
I boot into Windows and run CPUZ and it still reports 2400mhz and 266 bus!
I also tried increasing cpu voltage to 1.38v, didn't make any different
I also tried setting Dram Frequency to 720mhz or 800mhz, made no difference.

Any ideas on what I am missing? Wants to stick

E6600 Retail Processor
Asus P5B Deluxe Wifi with 0507 8/10/06 Bios
 
have you tried using the AI Booster program to overclock instead of using the BIOS? for some reason I can't change my FSB in the BIOS but i can change it (and it will stick) in the Booster program. also, what kind of RAM are you using?
 
I'll give that a try.

Using
OCZ EL DDR2 PC2-6400 / 800 MHz / Enhanced Latency / Platinum XTC Edition / Dual Channel (1GB x 2) 2gb total


Which the motherboard bios likes to detect on AUTO as PC2-4600
 
Well I tried AIBooster and it does nothing either, still stays at 2.4ghz with the same 266 FSB. I also tried changing the memory to DDR2-800 and it won't boot, have to switch it back to auto or anything lower than DDR2-800 (which it is!!) to get it to boot.
 
it's possible it's the RAM. OCZ seems to be either hit or miss for most people. any chance of RMA'ing it for some Corsair or Kingston?
 
have you checked the "Clear CMOS" jumper? i've heard some of the boards have come from the factory on the wrong pins, meaning that it will clear your BIOS settings each time you reboot. that would account for your changes not sticking. just a thought.
 
thanks Greg, but no its set right and the bios doesn't clear on reboot.

I'm also finding that if I force memory to DDR2-800 the system becomes unstable and fails Prime95 tests! So it seems either the motherboard or memory has an issue. System is stable at DDR2-533 including Prime95 tests and Memtest86 tests.

I've opened a post with OCZ Support as well on the subject of the memory stability.

My guess at this point is its a flaw in the P5B Deluxe board or bios.
 
What BIOS are you using? For overclocking try the 502 BIOS. Not the 507 (newest one). You can find the 502 on the ASUS site.

But it could be the RAM too, I heard bad things about OCZ so thats why I went with Corsair...

I had very similar problems, although my fsb would change, I couldnt overcloack with this board for anything. Bios 614 popped up out of nowhere and now Asus AI has me overclocked by almost 600 mhz with no crashes yet.

People keep posting infro and P5B deluxe Wi Fi, I was very very skeptical of this board after 2 days of crashes, no posts, and weird hangs when trying to achieve modest overclocks.

This is with what appears to be good memory.
