New, from RMA. Have changed to DDR3 inbetween so of no use at the moment.
The model is CM2X1024-5400C4 and is a 1024 MByte, two-rank DDR2 SDRAM DIMM. This memory has been verified to operate at 667MHz at the low latencies of 4-4-4-12. This module is also available in matched pairs of "TwinX" modules tested as a set in a dual channel DDR2 motherboard.
