I recently got a Gigabyte ep43-ud3l motherboard and i have and Intel Core 2 Duo E6700.
I have 4 gigs of Corsair xms2 ram (cm2xp1024-6400c4). When I have all 4 sticks in the system, the computer doesn't want to work. It just loops a restart over and over.
3 Sticks works fine (after updating the bios... used to only be able to use 2). The timing on the ram says 4-4-4-12, and it looks like the motherboard is running that automatically. Are there any steps i can take to try to get this 4th stick working? (All 4 sticks work individually in combinations of 1 2 or 3... just not 4.)
Other components. 6 Sata Hard drives, geforce gtx 280, xfi fatality titanium (pci express), corsair 750w psu.

I am not familair with your motherboard per se but as a general rule the voltage might need increasing for the memory and Northbridge.
-
I stepped up the voltages from 1.8 to 1.9. 2.0 and even 2.1 volts and nothing. As soon as I add that 4th stick, the computer doesn't make it to the bios, and loops a restart.

Which voltage are you talking about?
-
The voltage for the Ram, default was set to 1.8, and i went as high as 2.1 and it all works fine with 3 sticks in there, but when I add the 4th stick the computer cant boot up, and never loads to the bios screen.
-
2.1 is very high even for the RAM and I would recommend returning it to within normal parameters ASAP (1.9v max) Have you tried any small increase in the northbridge voltage(small increases!)?
-
Bro have you verified all sticks are good?
Tested each one individually in the 1st primary slot (2nd slot across usually) with memtest?
-
Have you put up the MCH Core to read 1.2 and the Dram Voltage to read 2.0 Also set your ram timings manually to 5-5-5-18. It could just be that the board don't like running with all 4 Dimms occupied. Why don't you post your M.I.T bios settings so someone can help you better?
-
When youi fill all the slots you generally need to increase the voltages to help with stability. All a bit of trial and error(just hopefully more trial less error) ;D

@fatman
Right now all my MIT settings are pretty much default. I have the Dram set to 2 volts and the MCH set to 1.2 volts. I can run 3 sticks this way stable. Ive tried changing the timings to 5-5-5-18 and with the same voltages and it does nothing. Its always the 4th stick...
-
Have you tried swapping the 4th stick around? Is it just the same stick or any stick that is a problem?
-
I would say it is a compatability issue with the ram. I would grab something else and run 2x2 sticks if you want to run 4gig memory. Look around and see if you can find others with the same board and what ram they use and try that.
