Hi,
I have just purchased and installed the GA-A75M-UD2H with an AMD A8-3870K FM1 3.0GHz 4MB 100W Black Edition processor and Corsair Memory 8GB (2 x 4GB) Vengeance DDR3 1600MHz DIMM 240-pin CL9 Low Profile memory (MFR # CML8GX3M2A1600C9 ).
All seemed to work fine until I started using Winrar and quickpar. I have been having errors with both programs but my laptop will unrar or repair with quickpar so I know the files are fine.
I have used memtest with the two sticks which come up automatically at DDR1300mhz in the BIOS and get all sorts of error messages. If I take one stick out it works fine but obviously it only works in single channel mode. If I try the other chip it again comes up with no error messages but reports the speed as DDR 800 when automatically detected.
I have updated to the latest BIOS (F5) but no solution.
Is it the memory that is faulty or is it the settings in the BIOS I am not setting up correctly.
Thanks
AR
