e6600, p5b dlx, ddr2-800 OCing question.

[Coles]

My setup-
e6600
Asus p5b deluxe non-wifi 0614 bios
Patriot DDR2-800
p180b with an added intake fan up-front
Corsair hx-520 psu
WD Caviar
x1900xt
NEC optical drive.

Last night I OCed it to 2.8 by using 400X7 and auto voltages and it ran great. Memtest and dual prime95s ran without a hitch for a few hours, it did get a bit hot.. 56c using coretemp with both prime95 torture tests running but I am using stock HSF.

I needed to download something that was gonna take all night so I wanted to put the BIOS back to stock since it was running hot and I didnt want to let it run all night at that speed til I get better cooling. So I went into the BIOS and put everything back to stock except the ram, which I dropped to 533mhz to match the stock e6600 FSB. After I did that the computer would boot but the screen would not turn on. I don't know if it was beeping cause the p180 doesnt have speakers, or any that I could find. But the HD light was flashing like it was loading Windows. So I booted my old comp up to see if my screen might have took a dump, but it worked. I then opened the case to my new set-up, took the battery out, jumped the jumper and put it back together and it booted fine. I even went back into the BIOS and put the settings back to how I had it when the screen would not turn on and it booted fine.

This is the second time I have backed off OCing in the BIOS to have the screen not turn on til I removed the battery and jumped the jumper.

Any help?

I have had this aswell .. Same specs bar the memory (G. Skill PK series). I had my system overclocked at 400 FSB times something (can't remember). Did memtest, wanted to exit memtest and the system did not boot. Had to use the jumper to get it running. No idea what caused this.

That temp of 56c was perfectly fine. Under a CPU stress test you're going to see temps that you'll never get under normal usage.

Make sure you're forcing your PCI-E to run at or around 100-110 and not too much more. It could be causing video problems.

Ya, but I had the boot issues after I put the BIOS back to stock, it would not reboot till I jumped and removed the battery. It booted fine at 400 fsb.

It probably didn't save the settings and you got a CMOS error that didn't allow a proper POST.

Anything I can to to prevent this from happening again? It's done it to me twice now and the fact that I have to remove my video card to take the battery out kinda makes me not wanna have to do it again.

Or is this all just a part of OCing?

If it works don't change it. That's how I feel.

Make sure you have PCI-e set to below 105.
I use 100.

I'm pretty sure setting it at auto causes it to OC along with the everything, & while i know you set everything back at stock, it was OCed just before that.

When you set the memory to 533MHz, did you configure the memory timings manually or by automatically reading from the SPD?

Also, if it happens again, try this procedure:

1) turn if off (if you can)
2) switch the PSU to off
3) press the computer power button once
4) switch the PSU back on
5) turn on the computer

I set the timing to 4-4-4-12 manually, and I will try that if it happens again. Thanks.

If I recall the vdimm at default is at 1.8v you need to up this to 2.1v
