1 stick at a time. Do all sticks let the machine work? If not, the sticks that don't let the PC work, what are they?
Mixing is just not a good idea. Too many issues can arise so don't mix.
I just purchased 2x 4gb kingston hyperx DDR3 1866 and tried installing it (everything was unplugged) and my pc continuously shuts off and turns back on every 3 seconds or so.
Specs:
Gigabyte GA-z87 HD3
Intel i5 4670k
crucial 2x 4gb ddr3 1600
I've combed through quite a few threads of similar issues with no luck. I've checked all the RAM slots and they work. I took the cmos battery out and restarted the bios. From what I've read I think its because the sets of sticks I bought are different speeds. Any solutions that don't involve me buying/returning RAM?
