To test the KHX13000D3 against the slower KHX11000D3 we installed a Core 2 Extreme QX9770 that runs at 8x400MHz with a resultant clock speed of 3.2GHz. To make things more interesting we increased the voltage to the CPU and Northbridge and raised the memory multiplier on our unlocked processor to 10x to give a nice round 4GHz clock speed.
Although the KHX11000D3 was happy to run at 1,333MHz on 1.7V it was unstable at 1,400MHz even though we increased the core voltage to 1.9V. If you’re using relatively slow memory it would seem that 790i Ultra offers less potential for overclocking memory than the P35.
Switching to the new KHX13000D3 at the same 1,333MHz and 1.7V resulted in performance that was very slightly lower, even though the latencies were identical at 7-7-7-20-1T. Using the same 1.7V we were able to raise the speed to 1,372MHz but the extra performance was quite negligible so it was time to give it the full 1.9V.
Immediately we were able to increase the memory speed to 1,600MHz which is the maximum that the BIOS can support on a standard front side bus. Memory and system performance both increased by a healthy percentage but we wanted to get more from the Kingston. Overclocking the front side bus to a modest 450MHz (equivalent to 1,800MHz) with a 9x multiplier gave a processor speed of 4.05GHz that is effectively the same as the 10x400MHz speed we had been using. The memory speed was still 1,600MHz as Nvidia appears to be doing some strange things behind the scenes with memory multipliers but memory performance took another leap forward.
All in all we were very impressed by the KHX13000D3 and feel that it would be a useful tool for overclockers but would we suggest that you buy it?
The answer is a firm ‘No’ and this is the reason why.
When we reviewed the KHX11000D3 just before the turn of the year it cost £290 for 4GB, which we thought expensive. However, even though the KHX13000D3 is faster still, there’s only 2GB of it. You can buy 2GB of relatively cheap DDR3 such as OCZ 1,333MHz for £95 or OCZ 1,600MHz for £150. If OCZ isn’t your cup of tea for some inexplicable reason then Corsair will sell you 2GB of DHX 1600 memory for £190. In short you pay a very high price for Kingston yet the benefit is unclear. Indeed, looking at a few of its other performance modules, it seems Kingston’s pricing is generally out of line with the rest of the DDR3 market. Of course, if these modules do start to drop in price then by all means consider them but, right now, we’d advise you to go elsewhere.

Kingston’s KHX13000D3 memory runs at an impressive 1,600MHz and delivers oodles of performance. The problem is that the price is so horribly high that it’s not a serious contender for your next PC upgrade.
