I'm stuck at +/- 380Mhz FSB on a QX6850 and the X38T-DQ6 version... reading this post I think I sould try another bios different from the F4a that i'm currently using. Will update the info later...

The Qx should be no problem. Fix the FSB at 266MHz, and increase the CPU multiplier. You'll be only left with vcore and PLL voltage to adjust. You can forget all the rest, your NB will be stock and the RAM too, so you can get your stable vcore/PLL combo for the speed you like.
After that, increase the FSB and decrease multiplier till you reach the speed you got in step 1
Now, you can tweak vFSBT, vNB, vSB, vDDR, timings, memory dividers...
Buying a QX to stuck at 380MHz is a total waste
OCCT 1.1.1a has a bug under Vista in RAM test.
There is a new version (1.1.1b) that works perfectly under Vista but it tests only 256M of RAM per core
"Update" from f4a to f3g, looks like it went well...Quote:

All Auto (just Strap @ 333).
Station Drivers is listing F7a beta bios for the X38-DQ6...so where is it?????
Website is back up.
Info from an Italian website:

X38 driver page update:
http://www.giga-byte.com.tw/Support/...ProductID=2665
Found F7a beta:

Get this beta instead

Unlike Prime95 blend mode, with only 1Gb on a quadcore, the FSB-NB-RAM are way much stressed. I never tested 500Mb on a C2D though, so can't compare. But look at the maximus thread. Many are now having their Prime stable, but not OCCT in RAM mode. If OCCT RAM fails, even F@H will fail from time to time on >12h run while OCCT RAM will fail in 1 to 2h. The new chips with a quad core are difficult to overclock because of an FSB-NB-RAM issue. Only OCCT in RAM mode unveals it, and F@H (but needs longer runs).
The Samurai in the maximus thread got his board at 3.9GHz on a Q6600 OCCT RAM stable
Great FSB in deed. Now, go for your maximum CPU clock. Impatient to see your results too
F7a beta is :banana::banana::banana::banana:ED UP!!....serious issues, as in the bios no longer detects my Plextor 716SA SATA drive....and once again you can't overlclock...as in setting my standard 425x8=3.4GHz....it won't POST.
It's screwed, back to an early bios me thinks...F3 perhaps.
No what now..i am REALLY getting angry with Gigbyte and the utter RUBBISH they pass off as bios....how long has the board been out now?????
Still not a single stable and final bios, i regret selling my P35 board now.
Nope, the prime issue is gone, now my cpu is at 3.843ghz and my ram has the occt issue even at its rated speed, even a bit lower, like i said doesnt really fail, it makes windows crash and occt still runs fine in the background, very weird.....its the only stability software i have issues with, im starting to question its credibility.......but i still have an issue with the 4:5 mem divider, sometimes it boots, sometimes it doesnt.
Ups, it is not a bios, it is a link to last beta of OCCT
I see, didn't note you were on Vista64. I can't answer you so as I didn't see many users tests on OCCT and Vista64, but OCCT is supposed to be Vista64 compatible
Hope you sort your issues. As long as there's some mutiplier errors in your RAM, you can't be sure of OCCT result. Also, the NB is much stressed with OCCT RAM, not only the RAM...
If you have time, I'll be interested if you can check OCCT RAM on bios default settings for every thing to be sure. Anyway, do it just if you have time, at least it can tell you for sure if it is your OC or Vista64
Anyway, hope these devider issues with X38 boards will be soon solved. Do you think they could be hardware issues as they are present on many different brand motherboards?
I'm playing with my new combo and i have a strange issue (i'm not a pro OC'er...)
I'm at 400*9 and when i put more than 1.55V on the cpu cpuz dint have that munch vdrop, but when i load it on prime the vcore raise to about 1.62!! Normaly it should go lower under load not higher!
If i put 1.500 or less it will drop on load...Did i miss something??
Be carefull with BIOS flashing and RAM frequencies.
Last night the MB was able to corrupt the boot block of both BIOS flash chips and the image on the HD.
Now the board is in RMA and I hope I can subsititute with an Asus.
Damn......
you make your post read like i was the one who had a flash failure.;)...not me!:)
yeah sorry about that haha it wasn't my intention.
the same thing happen to me , until i was able to OC my ram to 1120Quote:
I had the BIOS corruption not after a flash but after setting my memories at 1040 MHz.
The "funny" thing is that my DDR2 are PC-8500 (1066 MHz).

just you need some adjustments in the bios
