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