This is supposed to be a great motherboard for a workstation or even for an overclocking madman gamer as I understand, however I'm not overclocking... I'm trying to build a workstation capable of working 24/7 at near capacity if necessary (heavy number crunching) hence the Xeon CPU.
I have never built my own system before, so I'm running into all sorts of problems I've never encountered before.
As I said I'm not trying to set up RAID until I can get the RAM working... so I've set the controller back to AHCI mode.
System boots fine with just 1 RAM module but won't boot with 2. I sent the ECC RAM back because I could only get the system to boot with 1 module out of the 4. Still waiting for result of Kingston testing.
I bought 2 cheap modules of KVR ram 2x4GB (KVR1333D3N9K2/8G) while waiting for return of the ECC modules and this system will only boot on 1 stick, not 2. Either module will work, but not 2 together.
So after what you've said I tend to think maybe it is settings that need to be adjusted.
The ECC Ram is KVR16E11K4/32
