Hello everyone! To start off, here are my specs:
AMD FX-8120
Asrock 990FX Extreme3 (brand new)
Kingston HyperX 2x4GB DDR3 1866MHz (and a second, exact same kit)
ASUS Stryx R9 380 OC
XFX Pro 750W PSU
SanDisk Ultra II 240GB SSD
WD HDD 400GB
I recently got a new motherboard (Extreme3) to replace my dead Gigabyte GA-990XA-UD3. Here's what happens. Everything works perfectly with 8GB of RAM (only one 2x4GB kit) but when I stick in the second, exactly the same kit, I get no POST. I also get no POST if I put one stick in 1st and another one in the 2nd slot, if I put one stick in 1st and 3rd slot, everything works just fine and BIOS reports 1866MHz as it should. If I try with 3 sticks, no POST. If I put a stick in the 2nd and 4th slot, things work just fine. I also tried with my old 4x2GB Corsair 1600MHz. I put 4 sticks in all 4 slots and things work fine, except BIOS is reporting my RAM is at 1333MHz instead of 1600MHz.
Tried flashing BIOS, no joy. Tested each slot and each stick of RAM separately and everything is perfectly fine (lot of restarting...). Also, note that these 2 kits worked perfectly fine on my old motherboard.
I'm guessing this has something to do with voltages, but since I've never done any overclocking, I have no clue what I'm supposed to do. NB voltage is 1.145V and DRAM voltage is at 1.585V.
Thank you for reading.
