The Kingston didn't come close to its enormous 1,200MHz rated speed on our Abit P35 test platform but neither did the OCZ we used for comparison. Of course that's disappointing but the KHX9600 was rock-steady and delivered sterling performance at a surprisingly reasonable price.
Update
As pointed out by reader Lars Goran Nilsson, who just happens to be TrustedReview's former Technical Editor, the Kingston HyperX KHX9600 DIMMSs needs to be run at 2.3-2.35V to reach its potential.
With 2.30V for the memory and 1.41V on the Northbridge/Memory Controller Hub I cranked the front-side bus up and found that the Kingston would now run one notch above its previous best of 984MHz and was now happy at 1,025MHz. On a 410MHz front-side bus that's the difference between a multiplier of 1.2x and 1.25x - i.e. not very much. To add insult to injury the performance was slightly lower at the new speed.
The next speed option in the Abit BIOS was 1,230MHz on a 1.5x memory multiplier but the system refused to POST. I tried raising the CPU voltage by +0.2V to see whether more front-side bus was available but had no joy. I also tried dropping the bus speed down to 390MHz to bring the 1.5x multiplier within the 1,200MHz limit of the memory.
Again, no joy.
For comparison I plugged in the OCZ Reaper 1,150MHz I used in the original review and it too failed to respond to the extra voltage so it sounds like the Abit motherboard is the common factor here.
The moral of this tale is that decent memory is not enough to guarantee enormous overclocked speeds and if you don't read the specs of your components you're making life even more difficult.
Thanks Lars. Sorry Kingston. However, my original scores remain unchanged.
