Corsair 5400C4PRO / XMS 5402 V.1.1
As usual, Corsair sent us test samples of the high quality that we have come to expect. Twin2X is the name for a matched memory pair if we’re talking about DDR2. The name "PC2-5400" may be an allusion to the overclocking abilities of these DIMMs, as the standard calls 667 memory "PC2-5300". During our tests we were able to operate these DIMMs at 374 MHz (DDR2-748) and CL5-5-5-15 timings. All we had to do was raise the memory voltage from 1.9 to 2.0 V.
