BIOS recovery when OCing

[schnaz]

Hi all! This is my first post here on your forum, though I've been lurking a while now.

INTRO

----------

I'm fairly new to this whole overclocking business as I've recently built my first custom comp. I've hit an issue (not sure even it's an issue) that is getting a bit frustrating.

I've built my system around an i5-2500k, expecting to have a bit of OC'ing fun.

I've had it prime95-stable for 12 hours small FFT @4.6GHz /w 1.35V(bios) LLC1. I've since brought it down to 4GHz at the 1.25V the board gives as auto for stock clock, LLC off, and had it pass 24 hours prime95(FFT) and 100 runs in LinX. I havn't played any with the memory past setting it to the rated speed.

ISSUE

---------

I seem to be getting a (un)fair amount of BSODs. My tweaks in the BIOS are incremental and i prime the new clocks/voltages for 2-3 hours before moving on to the next. The thing is, if I don't stop prime AT THE POINT OF FAILURE i get a BSOD and upon reboot i get a BIOS checksum error, another reboot leading to the BIOS recovering to the f2 BIOS.

Having the to flash the BIOS after near every prime-fail is starting to get to me.

Anyone got any insight to share with this p00r n00b?

SIDE NOTE

---------

When trying to OC my GPU (ASUS HD6970), I get it furmark and Heaven stable (I think. I've done a lot more reading on CPU OC'ing) @950/1450 /w 1.175V, but when I reboot I get the BIOS checksum error mentioned above, with the following recovery malarky. I can't see what the BIOS and gfx card have to do with each other... Again, n00b :3

Thanks in advance!

Try leaving everything but Vcore and ram Volts on auto.

Set the ram timings and speed maually.

Then set your multiplier where you want it. disable speed step and everything else in the CPU tab so you have a static clock speed.

That's what I've done :/

(WOW! I was answered by THE tinytomlogan! Love your vids man!

I realize my OP might not be as clear as it should.

The problem I'm encountering happens while I'm playing with other clocks than the ones I am currently running.

4GHz/1.255V is stable. Please correct me if I'm mistaking, but I have no indication of the the contrary.

My BSODs occur while I'm playing with clocks that otherwise, as I understand it, should at worst end up with a prime rounding error. Not only do I get a BSOD, but the BIOS goes recovery mode on me. That's what is getting to me: Having to reflash the BIOS every other try.

To be clear: IS THE BIOS SUPPOSED TO RECOVER WHEN YOUR CLOCKS FAIL IN PRIME?

I was under the impression that you "at worst" had to reset CMOS. I've never had the luxury...

Can anyone with a relative experience with the same mobo tell me if this is normal?

Also, why does my GPU fiddling wind up with a BIOS checksum error???

I'm terribly sorry if I'm being a bother. Please point me in the direction of a good thread somewhere if this has been discussed. I simply can't find anything about this specific "issue" through searches. :/

I think it's quicker re-setting CMOS than flashing BIOS. I guess it's safer

 

[schnaz]

What's safer?

I just want to know if this is normal, or if i might have faulty HW (besides the SATA2 stuff).
