Gigabyte MA790FX DQ6

Don't worry about it.
Yeah I think I have covered all the bases. I have been exchanging messages with Gigabyte for the past 4/5 days. They have no idea about the RAM voltage problem and dragging it out and making me jump through hoops and now starting to go round in circles.
What's bugging me about the RAM is that I specifically chose this RAM as it is rated for 4-4-4-12 timings. Corsair have other PC2-6400 RAM at CL5 and PC2-8500 at CL5. I can't run it at EPP timings without an increase in voltage.
About the memory controller mutiplier. Gigabyte tried to increase theirs and they encountered the same problem. It stays at 2000Mhz regardless. They said they would get back to me after further testing. They got back to me today got and have given me beta Bios F6b which fixes this. I am very surprised nobody on here noticed this problem on their motherboard. I don't know if this BIOS has other changes.
The beta BIOS does seem to work.I was able to get the memory controller/CPU northbridge to 2200Mhz. I tried changing the multiplier to 12 for 2400Mhz and I could not get to Windows. Maybe the memory controller needs more voltage. It's a shame we can only decrease its voltage.

If anyone wants the F6b for the DQ6 BIOS just say so.

Hey!

I've noticed it today

The thing is, NB multi was working perfectly fine till I've put my new 2x2GB OCZ Reaper 1066 set. Then it stuck at 10x! (looks like 2x2GB is triggering this behavior, could also be related to 1066 mode - need more time to investigate, but today is F1 quali at the top priority)
I'm glad you have beta BIOS. Can you share it with me? My NB is happy at 2.4GHz and 1.25V but I need 11x NB multi for that

Thanks!

BTW so far quick testing took me up to 1180MHz 5-5-5-15 2T at default settings (Auto timings, EPP voltage=2.1V)

PS. Regarding your memory voltage problem, I can only say it is working for me fine....
