Greetings Forums.
I have an ASRock 990FX Extreme 4 with Kingston Hyper-X Preditor DDR3-1866 RAM.
When I only have slots A1 and B1 filled, with two 8GB DDR3-1866 DIMMS respectively, it recognizes the correct speed of each dimm.
However, if I fill all four DIMM sockets with the same 8GB DIMMS, the speed is decremented to DDR3-1600.
I have flashed the UEFI to the 10/2/2012 build from ASRock's website and no changes were observed in this problem.
(However, I have this nifty new Astronomical photo in the background of UEFI, so I know it is the new ROM installed.)
The list of "tested ram" is a joke because they list stupid dimm sizes that would never be used, like 2GB blahblah, for 1866.
Any assistance is appreciated.
It is almost like this board is designed not to have access to 32GB of RAM at the native FX-8150 socket speeds of 1866, even though it is supposed to support 2166(OC) speeds and default to 1866 for FX series chipsets.
I have attempted to set the appropriate features within the UEFI interface, to no avail.
It just fails to reboot and then the UEFI defaults are restored and all four slots indicated 8192MB (DDR3-1600)
I am at a loss.
Any assistance is appreciated.
