The recently announced HP2-6400 comes to fulfill the needs of ordinary and professional users with good memory speed and overclocking performance. The HP2-6400 is designed to run at 400MHz, with enhanced latency of 4-5-4-11.
In our tests, the modules reached 475MHz with voltage up to 2.25V. In order to achieve higher operating speeds, we had to relax the timings to 5-5-5-15, but leave the voltage stable at 2.25V. At 400MHz, the memory can work with tighter timings than the specifications (4-4-3-11), resulting in good performance. Unfortunately, we couldn't reach 500MHz where the memory simply refused to work, but at the last minute (and after our tests had been completed), Mushkin did provide us with a tip concerning the Asus P5B Deluxe BIOS settings which could give an extra boost.
Ending our presentation of the Mushkin HP2-6400 2x1GB kit, we were pleased with its performance and retail price of ~US$273. Users can buy the memory directly from Mushkin. Overall, a good product that keeps its promise of "...low-latency performance at an affordable price..."
