I bought this board today:
ASRock 880GMH/USB3 R2.0 And 2 DDR3 2GB RAMs (takeMS "TMS2GB364E082-139CM") Power = 300W.
The problem is that I get bluescreens (during installation of Windows 7) when I use 2 of the RAMs (4GB).
But if I install only one (doesn't matter which one) the system works, no crashes or bluescreens.
I tested them with memtest86 and here the same problem: the test crashes (computer reboot) when I use 2x RAMs (4 GB) after 10 seconds. And no problems or any errors are shown when used separately.
Any idea whats wrong?
