Thanks, but I have populated all the memory slots correctly.
My problem is that it is still appearing (in BIOS) to be working in "Independent" memory config.
You reckon it is not a CPU related issue?
Indeed I reckon the version is 28 (since I do not have access to the machine at the moment). But I do not see any info in the release notes about that issue (in versions above 30). I will perform a BIOS update as soon as I can, and report back.
Just checked the firmware: latest version of BIOS (and BMC/ME/FRUSDR) installed - version 30.
Problem is the system still does not use memory modules in dual-channel. Not even when only 2 memory modules are installed.
Current configuration has an Intel Xeon E3-1240 installed, and 4 memory modules KVR1333D3E9S/4GI (Intel validated).
So why is it not working in dual-channel mode?
FYI: The issue is caused because of a BIOS display bug. It seems that memory dimms work in dual channel, but that info is not displayed in BIOS.
Should be remembered for further reference.
