Error code on Gigabyte Motherboard GA-Z97X-UD3H-BK

Hi Experts,

I'm getting the following error code on my mobo I believe its the model shown above(!), every time I try to upgrade the memory to 24GB from 16GB I get the following error code on the LED display.


Looking online it looks like the error is ''CPU status flag test, CPU register test, memory refresh test.'' Does anyone know what this means?

is the ram upgrade the same model as the installed ones?
if not that is probably your problem - or maybe it's simply bad
did you try with only the upgrade ram stick installed?

No its the same type of RAM and I have replaced a working RAM module with the third module just to make sure it works OK, and it does. I did also put the RAM modules into the other two slots as it could be a defective slot on the motherboard. But they again worked correctly.   The machine itself does have a 520W PSU and I'm wondering if that is not enough for the upgraded part. It has a Xeon processor and a dual Intel NIC too. A rather basic graphics and sound card. It's more of a server really than a home PC.
what is the slot occupation ?
since you have dual channel architecture - that can be your problem, having 2 sticks in dual, and 1 in single channel
from the manual pg 16 :
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that memory
of the same capacity, brand, speed, and chips be used and installed in the same colored DDR3
sockets. For optimum performance, when enabling Dual Channel mode with two memory modules,
we recommend that you install them in the DDR3_1 and DDR3_2 sockets.

Yeah great call on that one, looks like I can't install in three's I'll order an identical module this afternoon and will let you know although I think you may have nailed it.
i did not use nails...only consulted the manual -  and my memory
let's hope that fixes it for you
