Kingston KHX1866C9D3K2/4GX review
While most budget RAM has an XMP profile that takes the memory up to 1,600MHz, the Kingston KHX1866C9D3K2/4GX goes one step further with an impressive headline speed of 1,866MHz. On paper, it makes this an interesting kit that could be a stunning performer.
It looks great, too, thanks to Kingston's bright blue aluminium heatspreaders that will help keep each 4GB DDR3 DIMM cool, particularly when it's run at its maximum speed.
The default SPD settings set the RAM to run at 1,333MHz. At this speed we were a little disappointed to get an overall score of just 98 in our benchmark tests. While by no means slow overall, this memory lags slightly behind other kits that we've tested.
Using the XMP profile to push the memory up to its maximum speed of 1,866MHz, we saw a massive speed increase, with the overall score jumping up to 104. While this is a huge improvement and one of the biggest increases we've seen going from SPD to XMP profiles, the fact is that cheaper, slower-rated memory also scored similarly in our benchmark tests.
Given that the Kingston KHX1866C9D3K2/4GX is also comparatively expensive, we'd rather spend our money on the cheaper Crucial BL2KIT25664BA160A, which scored similarly in our benchmarks when run using its XMP profile at 1,600MHz.
