Bios saves OC settings, loads stock speed

p35-ds3r (F7D Bios), e2180 @ 3.4ghz 1.437v (10*340), OCZ Reaper PC2-6400 HPC (rated 4-4-4-15, running at 4-4-4-12, 2.1v), BFG 8800GTX OC.

I tested a few days ago the 3.4GHz overclock, and it ran for over 17 hours stable on Orthos. Super Pi ran fine as well. I was working on a review and I was pushing my memory, 5-5-5-12 ~980mhz.

I booted into winxp sp2 fine, however it crashed under dual super pi 2M. Now whenever I boot, the computer loads at 10 * 200, but yet all the settings are saved in the bios as they were when I overclocked it (voltage, 10 * 340, memory timings etc).

I also tried saving settings to CMOS (using F11) but to no avail. I am completely clueless as to how my settings can be saved and yet the computer runs on stock speed. :help:

Also, easytune (GA's mobo tweaking utility for windows) has the overclocking section disabled. I never use it to overclock, but this was something I thought may be significant to share.

Anyways, if anyone has any thoughts I'll owe you big time.

have you tried clearing the cmos/bios and starting fresh?

You may have triggered some protection feature. or gremlins.:ph34r:

The issue lies somewhere else... your OC is not stable. The Gigabyte boards have a Dual BIOS and it protects itself when an oc is unstable by booting with default values. If you're testing your Ram, either lower the multiplier, loosen the timings or increase the Volts then reboot. I'm pretty sure it will work. From what I have read, the Reapers are not great oc'ers though...

And just a hint, lower the CPU multi and raise the FSB. You'll have better overall performance and may help oc'ing higher. Example:

10 x 340 = 3400
9 x 378 = 3402
8 x 424 = 3400
etc.

Check out my sig and the E6400. Default is 8 x 266, but its running at 7 x 490Mhz (3.43Ghz).

I think what did me in was pushing the OCZ Reapers so high, since they were fine at my previous setting. Man, talk about getting sucked in by some nice looking hardware.

I'll reinstall the bios and see if those gremlins get kicked out...:ph34r:

Thanks for the help.
