Asus Z170-e RAM works on A2 but doesn't work on B1/B2 when video card is installed.

[JamesNYC1]

new system:
OCZ 600W PSU
EVGA DDR4 3000 ram 8gb * 2
i5 6600k
asus 710-e

The interesting part is when I install one ram on A2 and B2, every thing works fine with stress testing.

Now after I added video card: HD 7770, the stress testing failed. And I removed ram from B2, stress testing went ok. I remove ram from A2 and install on B2, stress testing failed.

Both ram has tested in A2, so its unlikely the ram issue.


What can go wrong?

1| You forgot to include the OS and the model of your PSU.

2| Have you tried borrowing a PSU of at least 500W from your friend and seen if the ssytem powered up without issues on the ram?

3| Per your manual, page 1-10, if using only one stick of ram - it goes into DIMM_A2 only. So the reason for B2 not working when all other slots are empty, is void.

4| You may want to inspect your CPU socket for any bent CPU socket pins.

5| Make sure your BIOS is up to date.
