OCZ Reaper HPC 2GB PC2-8500

Performance:

Using an ASUS P5N-E SLI motherboard with an Intel Core 2 Duo E6400 processor, we were able to push the memory up to DDR2-1125 speeds using the EVP voltage. Tweaking the timings and taking other steps had not allowed us to push the memory any further while remaining stable. We had reached DDR2-1140 speeds, but on boot we would experience kernel panics with Linux. Along with the P5N-E SLI and the Core 2 Duo E6400, other components used included a Gigabyte GeForce 8500GT, Western Digital 160GB SATA 2.0 hard drive, and SilverStone Zeus 750W power supply. On the software side was Fedora 7 x86_64 with the 2.6.21-1.3228.fc7 kernel and the NVIDIA 100.14.11 display driver.

For the benchmarks we had run the memory at DDR2-800MHz (E6400 @ 2.14GHz), DDR2-1067MHz (E6400 @ 2.84GHz), and DDR2-1125 (E6400 @ 3.00GHz) using SPD timings. At DDR2-800 MHz speeds, we were even able to lower the memory timings to 4-4-4-12. For comparison, we had also retested the OCZ Flex XLC memory when running at DDR2-800MHz speeds with the default timings. The benchmarks being used included Enemy Territory, Quake 4, LAME compilation, LAME encoding, and RAMspeed.
