Yeah, I'll have to see what happens when I put the old CPU back in I'll let you know. Cheers

It worked with both previously. I then upgraded the CPU to the above mentioned one, now it will only boot from one RAM. The BIOS was updated before upgrading the CPU.

Hi all,Just a quick question to see if anyone has come across the same issue as me before.My problem is that my pc won't boot when two sticks of RAM are installed. The RAM is not faulty. I've run memtest, and came back with no errors. I can take out one stick and PC boots fine. I can even swap the ram with the other slot (only have x2) and still boots. As soon as I install two, PC hangs either on windows 7 logo or doesn't even get that far.I've tried reseating the RAM, even CMOSing motherboard to no avail. I don't get any beep codes or anything.PC specs:Asus A55BM-A/USB3 motherboardX2 Kingston KVR16N11/4 GB sticksAsus R7240 graphicsX4 870K CPUAny help would be awesome.Cheers
