IBM 00D4955 4 GB (1x4GB DDR3-1600)

The IBM 00D4955 4 GB comes as a single module with 4GB of DDR3 on board. Operating voltage sits at 1.35V. It is rated at 1600 MT/s with a CAS latency of 11, working out to a true latency of about 13.8ns. Once memory clears 3600 MT/s, frequency gains taper off, so the 4GB on offer here is the spec that counts for esports and everyday use.

As a high-end DDR3 kit, it slots naturally into older AM4 and LGA1700 boards that top out at DDR4. Its $150.00 price tag places it squarely in high-end territory.
