When benchmarking the HyperX PC2-8500 I wanted to be sure to cover all angles. Some people like to run their memory at low latencies, some like to run their memory at high frequencies, whilst others prefer a mixture of both settings. Below is some information regarding the testing procedures and their results:
Stock Settings (5-5-5-15 / 533mhz)
A problem often seen with memory modules is their inability to run at stock timings, an issue we've often encountered here at OC3D. However, I'm pleased to say that the Kingston HyperX PC2-8500 overcome this first hurdle without any problems, successfully running at DDR-1066 with timings of 5-5-5-15 on a stock voltage of 2.2v.
Lowest Timings at Stock Frequency (4-4-4-8 / 533mhz)
Not everybody will be able to make full use of the extremely high frequencies that this memory is capable of, and for that reason it's always good to know you can reduce the timings of the memory to obtain a healthy performance increase.
For this test I ran the memory at stock speeds, but increased the voltage slightly to 2.3v to allow for a bit of extra headroom. After many resets of my system to find the optimal settings the HyperX PC2-8500 showed it was capable of an amazing 4-4-4-8 whilst running at DDR-1066 (PC2-8500).
Highest Frequency at Stock Timings (5-5-5-15 / 566mhz)
Increasing timings in exchange for higher frequencies is not something that everybody is comfortable with. For this reason, I left the HyperX at its stock timings of 5-5-5-15, applied 2.3v and proceeded to see how high I could push the memory on the MHZ scale before it topped out.
The maximum achievable overclock was DDR2-1132, not bad at all considering the board only allowed me to increase the voltage up to 2.3v. With a little more voltage I am confident that the memory could have been pushed quite a bit higher.
Highest Frequency Overall (5-6-6-15 / 575mhz)
In this test I proceeded to find the maximum MHZ speed at the cost of slightly looser timings (5-6-6-15). The maximum stable overclock came in at DDR2-1150 which is very impressive considering I was unable to increase the memory voltage past 2.3v on the test motherboard. I also believe that the overclock was slightly hindered by the capabilities of the AW8D motherboard at high FSB speeds.
