Hello everyone, I recently upgraded my CPU/MB/RAM and was building my friend a PC with my old hardware, which is:
ASUS Z77 Sabertooth MB
i5-3570k
Corsair Vengeance 8GB (4GBx2) DDR3 (1600mhz)
Never had any issues with the setup preupgrade. RAM was in dual channel in slots A2 and B2 (The recommended slots via manual) running at 1600mhz.
Ever since transferring the MB/CPU/RAM to a new case, the right 2 RAM slots, B1&B2, will not work. If I put on of my sticks in there, the DRAM LED lights up and the system wont post. Even after trying MemOK. I took out the one stick on B2 and left one in A2, the system boots fine and sees 4GB. I have tried both sticks in this slot and each of them works and boots. If I try to put both sticks in A1&A2, the system will still boot but the stick in slot A1 will not be recognized in Windows, however, the BIOS does say there is a stick in there.
Any other combination will not allow the system to boot.
I have checked all power connections, everything seems just fine. The power supply is 500w, plenty for what this system needs. I flashed the BIOS to an older version thinking maybe something went weird, that didn't help. I tried the jumpers on the MB as well, and that did nothing...
Anyone have any ideas as to why only one slot is working now?
Thank you
