Hello,
I have Gigabyte GA-MA770T-UD3P board for almost 5 years now. Everything worked okay. Yesterday, I wanted to upgrade my RAM. I have 2x2GB Kingston RAM, running in dual channel. I have bought one 8GB stick of Patriot 8GB DDR3-1333MHz CL9 RAM. When I add the new RAM to 2x2GB Kingston sticks, the board simply not boot. Fans are running, LEDs are on, but there is no display, no bios, nothing.
Everytime if there are new 8GB Patriot RAM and at least one 2GB Kingston (or both of them), the board will not boot.
If is there 2x2GB Kingston, or 8GB Patriot RAM alone, board boot okay. I tried to reset CMOS, but not helping.
Every RAM I have is DDR3-1333Mhz, CL9, but Patriot is single side. Kingstons are double sided.
Is there some incompatibility?
-
It is best not to mix ram unless it is same size chips. Since it runs with either 2 x 2 or just the 8 gig chip it is incompatibility
-
Yes, I also considered that. I am working in IT service, and I have seen incompatibility like this only 1-2 time in my life...so I thought it is like impossible thing :-)
Now I am sure my board dont like mixed modules.
p.s. With that 8GB patriot and another 2GB patriot is boots just fine :-) I have 10GB RAM now. Maybe is a brand problem, or single/double sided sticks, or memory chips ...

You are running it in single channel mode so probably helps. If you can find a setting in bios under ram called ganged or unganged run it in unganged might help.
