Hi,
As my LGA775 mobo died I decided to do a little (and very budget oriented) upgrade - Ryzen 3, Asrock AB350M-HDV, 2x4GB Ballistix 2666 CL16 RAM. That RAM is on the QVL list of the motherboard, at least for Raven Ridge. CPU-Z or HWInfo64 readouts look perfectly normal:
So what's wrong? Well, my OS (64-bit freshly installed Win10) says that there's just 3,93GB of available space out of 8GB installed. More - BIOS from the very beginning shows that my RAM runs in single channel only:
Even though it identifies it correctly:
As for XMP there's only one profile that I don't know if loads correctly because if I choose it my mobo fails to post three times and then loads the defaults (which appears to be still 2666?).
I tried different hings like swapping the banks, manually lowering the frequency to the base 2133MHz, increasing the voltage to 1,3V, no result - three failed posts and succesful loading of the defaults.
Any tips what else can I try? How can I determine which part is faulty (if it is) when I don't have an access to modern computer parts? Thanks for any help.
