OCZ has released a new addition to its DDR2 Reaper HPC series, the 4GB 1066MHz DDR2 kit.
This kit works at 1066MHz with EPP 5-5-5-18 latencies at 2.1Volts. The kit comes on an all-black PCB paired up with Reaper HPC cooling system which should provide efficient cooling for your overclocking needs. It also has extended voltage protection of up to 2.15V which allows the voltage to be raised without compromising the lifetime warranty.
The Reaper HPC edition at this speed is also available as a 2GB kit, which works at 5-5-5-15 latencies from 2.1 - 2.3V and has EVP of 2.35V. The 4GB kit isn't yet available, but the 2GB kit can be found for as little as €100,25 at K&M Elektronik AG in Germany.
