Kingston HyperX KHX11000D3LLK2/2G - DDR3

There are a number of technical differences between DDR2 and DDR3 such as the bank arrangement, operating voltage and the signalling system called ‘fly-by', but broadly speaking we can ignore all that. DDR3 takes over where non-JEDEC speeds of DDR2 left off, so the pecking order is DDR2-667, DDR2-800, DDR3-1066 and DDR3-1333.

Kingston hit the heady heights of 1,375MHz with its HyperX KHX11000 DDR3 memory, which looks incredibly under-stated in its blue anodised aluminium heatspreader. There's little about the appearance to suggest that Kingston is at the cutting edge with new technology, apart from a small DDR3 logo, but we were keen to see whether this new type of memory would give the E6750 processor a new lease of life.

On Auto settings the Gigabyte wanted to clock the memory at 1,408MHz, which seemed extreme and this was confirmed as the test system wouldn't start Windows. We did a quick run on the standard 333MHz FSB with the memory running at 1,066MHz and found that performance was exactly the same as the PNY DDR2 memory running at a measly 800MHz.

It was time to get some proper performance out of the Kingston HyperX. However, we were staggered that we simply could not overclock the processor by a decent amount with this memory and the best we could get was an FSB of 360MHz with a memory speed of 1,150MHz. Performance was, as you would expect, dire and when you consider that the memory costs £287 it is probably best that we draw a veil over this particular DDR3 and move on swiftly.
