My computer has 2x2GB RAM right now and this works fine. I got one stick (from another computer) that is 8GB and I want to put it into my computer. All memory is DDR3.
However, the computer does not boot at all if I have a single stick in any of the channels - it just sits there with a black screen and doesn't even go to BIOS, so I have no idea what it's upset about.
I have tried:
- Putting 8GB into slot 1 (out of 1-4), no other RAM. Same problem. I've tried it alone in all four slots.
- Putting 2x2GB into slots 1+3, 8GB into slot 2, same problem
- Putting 8GB into slot 1, 2x2GB into 2+4, same problem
- Putting 1x2GB into slot 1, no other RAM. Same issue.
- Increasing the DRAM voltage slightly (to 1.51), same problem.
- Changed the DRAM timing to match the new stick, same problem.
So I don't think it has to do with the RAM stick itself, but rather the motherboard or the processor I guess. I was under the impression that all motherboards would support a single RAM stick regardless, but apparently that isn't the case?
- CPU: AMD FX-8320E
- Motherboard: MSI 970
- RAM 2x2GB: Corsair CMX4GX3M2A1600C9
- RAM 8GB: Corsair CMV8GX3M1A1600C11
My BIOS is up to date (M40). What could be going on?
Edit: I think it's the RAM stick. I got my computer to boot with 1 or 2 of the 2GB sticks that I currently use after resetting the BIOS. But I cannot get this new one to do anything. Oh well, guess it's back to the store tomorrow!
