So last week i bought the Asrock 890GX motherboard from Newegg and the "CORSAIR XMS3 4GB 240-Pin DDR3 SDRAM DDR3 1600 Desktop Memory Model CMX4GX3M1A1600C9". Set it up and found that i was getting a error 54 which according to the boards book is "unspecified memory initialization error'. I took everything out of the case and tried the memory in each slot, reset the bios constantly and nothing on screen, no post. I looked on the MEMORY SUPPORT LIST on Asrock's site and ordered the "Kingston Technology Hyper X 4GB 1600MHz DDR3 Non-ECC CL9 DIMM (Kit of 2) XMP X2 Grey Series KHX1600C9D3X2K2/4GX" got them today and its the same problem. I have a PII 955 and a AMD XFX 6870. I took everything off bare and still i am getting error 54. Any idea on what is going on? Thanks in advance.
