Hello all! I have a Gigabyte X58A UD5 (Rev1) that im running with 3 x 2GB sticks of kingston hyperX 2100Mhz CAS 8 memory. The issue is it will only run at 1066. IT will boot into windows in XMP1 at 1860Mhz but will shut down. In XMP2 it will not even boot and I get a screen telling me I have boot issues due to overclocking. I tried disabling turbo and setting the memory at 1.65V manually but with no change. Anybody have some advice for me? Im thinking about getting the new version of this memory at CAS11, Thinking this may be easier for my mobo to run. CAS8 is pretty tight timings for 2100Mhz i think. None of the memory on the compatability list are available any where. I have also flashed to the latest BIOS F7. Thanks!
