Test System

• AMD Athlon-FX53 (max: 2.9 GHz)
• MSI K8N Neo2 (Bios 1.5b1 - max HTT: 345 MHz) (nForce 3 Ultra, DualChannel)
• X800 XT PE
• Antec 550 W PSU

Overclocking

After some testing we could reach 202 MHz @ 2-3-3-X-1T and 227 Mhz @ 2.5-3-3-X-1T, completely stable. So the memory is able to reach the advertised DDR450 speeds, but not much more. Increasing voltage from 2.6 V up to 3.6 V did not yield any higher overclock. Reducing the timings to 3-4-4-X-2T did not help either.

Testing

The first thing we noticed was that the memory has absolutely no problems running at a command rate of 1T. Value memory often can't run at 1T and requires a command rate reduction to 2T, resulting in a loss of about ~200-300 MB/s.
