If you own a Canterwood or Springdale board, or have some mutant nForce2 board that can hit 250FSB, dual channel PC-4000 memory will help reduce the clock buffering penalties currently associated with asynchronous RAM settings. Performance arrives with a considerable cost, though. A brief look through on-line e-tailers puts the sample 1 GByte OCZ EL-DDR PC-4000 Dual Channel memory kit at comfortably over £300.
