I put 4 4GB sticks in my ASUS G53 notebook, and memtest86 is giving me errors. CPU-Z says they're running at 1.50V, CL/tRCD/tRP/tRAS of 9/9/9/24. Unfortunately I'm running twinned pairs, Corsair in slots 1/3 and Micron in slots 2/4, which I hear is bad news (the pairs themselves are supposed to match one another).
Is it conceivable that the problem could still be the mismatched pairs, or does the fact memtest86 shows errors conclusively indicate the problem is a specific piece of hardware (eg a bad stick or a bad mobo slot, or RAM not seated properly)? If I remove one pair and see no errors, I'm wondering if I can be sure that one of those sticks is bad, rather than that those sticks are fine, but they can't be mismatched with another pair. (disassembling to test is a bit of a procedure for this laptop, so I want to minimize how many times I do it)
I assume there's no way to disable certain slots to identify which stick is bad without removing the RAM? I can see no obvious way in memtest86 to test individual sticks.
