Gigabyte 965G-DS3 BIOS OCing issues

[The0ne]

I've had this happened to me on all 3 of my boards now. With original bios, F7, intact I'm able to OC my FSB to 450Mhz and it'll run stable. I did this with my first build and it ran for 4 months I think. Then I figure I update the bios for the heck of it and when I did the PC would not boot up. I had to set the FSB back down below 300Mhz now for it to boot and run stable. I can no longer achieve 450Mhz even with the F7 BIOS.

Then on my 2nd build I use the same memory, Super Talent 800Mhz (I bought 4 of them in pairs), and was able to acheive 420Mhz. Forgetting that I shouldn't be upgrading the BIOS it happened again. The third time was because I was playing around with the BIOS Run utility. In any case, updating and reverting back to the same BIOS revision did something to the effect that I can't acheive the FSB I had once did.

6320, Q6600
7900GTX, 8800gts
ST 2gig dual channel 800Mhz
Antec 430 PS, Ultra Xfinity 600 PS

I'm pretty pissed as I had it running stable for many months until deciding to update the BIOS. I knew better but was dumb at the point in time I guess. Still, why can't I get the same benefits by reverting back? Anyhow, anyone have this similar problem or can provide any advice? Thanks.

You've obviously just forgotten a setting, that's holding you back, since if you've reflashed to the same BIOS that was giving you 450 Mhz FSB, it still would be, if all of the settings were the same.

It does sound obvious but I've set the settings back to what they were. Doing this prevents the system from running as the FSB. My first setting is to try FSB at 300Mhz with everything on auto. This doesn't even work. Then I bump up the voltages one at a time....cpu, memory, mch. This doesn't seem to help much either. I certainly don't want to bump the voltages up more because I don't believe the components need the extra juice. It didn't before at 400Mhz so why at 300Mhz. The memory, although rated at 800Mhz, can be OC to 1000mhz as many have done. It is the one reason why I bought 4 gigs of them.

There isn't anything I'm doing different or changing for the fact besides the Bios. I have other guides with their settings they've used for this particular MB and it's not helping. Simple fact is increasing just the FSB slowly from 266Mhz to 300Mhz+ is painful now. There isn't anything simpler or more obvious than by doing this.

There's something funky about Gigabyte's BIOS. I've encounted similar issue after a flash. Something isn't being updated when you go from one BIOS to another. Search the net and you'll see similar complaints. Fortunately, this is not a widespread bug.

Give F4 a try .. I went to F11 and lost my OC .. Went back to F4 and all is well..
