I have my Q9450 OC'd to 3.0 (375 fsb, 8 mult)

If I restart my computer nothing happens, but when I leave my computer off, say ... overnight and I start it up:

It goes to BIOS, then like I modified some BIOS setting, restarts *then* loads windows. I then restart and go into BIOS and see that my option to enable me to change the core clock has been disabled.

Why is this happening? Is my little mobo battery bad or something?

Mobo: Gigabyte GA-EP35C-DS3R
BIOS: F2

I should mention that once I change my FSB back up to 375 (instead of 333) my computer is fine, I can leave it on for hours no problems, play Call of Duty 4 with no problems etc...
So I don't think it's a stability issue?

I should also mention its my first OC.

Let me add first that I have the voltages set to AUTO in my BIOS.

My ram is currently set at 900mhz

Not sure how to get northbridge voltages?

NB voltages can be easily found in the bios, so you'll have to look there.

If you're desperate, one way to ensure that a part of your system isn't stable is to drop your cpu multiplier to x6, and perhaps drop the vcore to a setting where you know it's stable. Then run Prime95 blend test for 24hours. Should it fail, your ram or motherboard is the culprit.

I suggest 24hours because according to my experience, my pc was stable for 12hours, yet it kept crashing occasionally. Upon running blend test, it went bad at 12hours and 1sec.

mine never crashes, just disables the core clock (instead of the enable option) in bios when its off for a certain period of time.

There was a function called EIST or something in the BIOS that was enabled that had something to do with controlling the core clock. I disabled it. Was that my problem?

Reply to Shocking

^No that is not the problem.

See:

for explanation of BIOS options and OCing how to. It is specifically written for the DS3L; but options should be smiler/same.

Btw; many people seems to have problems with P35C chipset. A BIOS update (if it applies) might help.

Not sure it will... the only BIOS drivers available besides the one I have are beta drivers.

Reply to Shocking

I disabled the legacy USB option, that was the problem I think
