Primarily, I suspect that anything over about 1600MHz is going to |
60 |
require poking the bios (or uefi) to actually run it at its spec'd |
61 |
clock (enabling following the XMP profile defined by the ram, if the |
62 |
mobo directly supports doing so, is usually all it takes), otherwise |
63 |
it down-steps to either 1333 or 1600 as 'standard' defined speeds for |
64 |
ddr3. As for why it's not reporting the product, vendor, and s/n's |
65 |
properly, I'm not sure. I'd try swapping them to see if the issue |
66 |
moves with them, but as long as they're actually able to run stable |
67 |
(and reliably) at their spec'd rates, and they really are the sizes |
68 |
they claim, I'd be inclined not to care whether the nvram values |
69 |
beyond the speed profiles are read properly. |
