Keenan, could you please give me a screen shot of your bios overclock settings?
Also, what banks are your DIMMs in? I see two blue banks, near the cpu socket and two white banks further away. Which banks did you put your modules in?
The motherboard manual says to put both in either the two white, or the two blue, but my previous experience with GIGABYTE Mobos, the manual had it backwards.
I know I am either using the wrong banks, or I am overvolting the wrong setting, because my NB will not go higher than 2200, using a 720BE with DDR3 1600.
On my M3A78-T (AM2+ / 720BE), I can set the NB to 2800.

Dont have a cam handy, but i'll type you a little note...
This is exactly what I use...
* ACC = Disabled
* Multiplier = 19.5
* Bus Speed = 200
* Motherboard = Gigabyte GA-MA790FXT-UD5P
* Memory Speed and Timings = 2 x 1GB 1333Mhz DDR3 @ 8-8-8-18
* NB Frequency = 2.8Ghz
* HT Frequency = 2.6Ghz
Voltages
* NB voltage control = +0.1V
* SB/HT volatge control = +0.1V
* NB/PCIe/PLL voltage control = +0.1V
* DDR VTT voltage control = Normal
* CPU NB VID control = +0.250V
* CPU VID control = +0.250V
I use the 2 blue banks, when I first used them and saw my memory was running at 64bit I thought, how is this possible, but then I saw the setting for ganged and unganged
I take it you dont need any info on what that means..?

Ok, so I got it working, and here are my results on my GA-MA790FXT-UD5P
I set the voltages, save/exit soft restart, set clocks except northbridge, everything was fine and repeated the save/exit.
However, when I set the northbridge to anything above 2200 it got mad and I ended up having to clear cmos and start over, so I did some investigating.
Found out that on my board, as long as you don't do a cold/hard boot with the northbridge over 2200 Mhz, I could continue to save/exit with a soft boot and increment the NB 200 Mhz at a time, until I reached 2800.
Computer ran fine until a cold boot.
So for some reason, it seems like it has a problem ramping up the voltage and clocks to 2800 on the northbridge from a cold boot. For now I left the NB at 2200, with the voltage at +250.
Any thoughts?

Got that exact same issue with mine, just did my first cold boot...
Sad thing is tho, the higher your NB, the more you feel the performance gain.
2200Mhz should'nt realy need any added voltage![]()

I am thinking about this board and a 945 when it hits.
I am pretty satisfied with what I have though and am not sure I'd get much in a move to DDR3.
Can anyone who has this motherboard please do me a favour and tell me how hot the heatsinks on the PWM and SB is, Mine is really hot to the touch and I dont know if that's any good..?
