Corsair 4400C25: Taking Samsung TCCD to New Heights

Intel Performance Test Configuration

The Corsair TwinX1024-4400C25 was also tested in our standard Intel Pentium 4 Memory testbed. The hardware is the same used in our earlier reviews of DDR400 and faster Memory. All test conditions were as close as possible in these tests over time on the Intel test bed. We also eliminated from our charts any known memory that has been discontinued.

We have found the fastest performance on Intel 865/875 to be achieved at Cycle Time or tRAS of 5, or the fastest tRAS setting that is stable with the tested memory. Intel platform benchmarks were therefore run with the fastest stable tRAS timings that we could achieve with the Corsair 4400C25.

Test Settings

We ran our standard suite of memory performance benchmarks. The following settings were tested with the Corsair DDR550 memory:

1. 800FSB/DDR400 - the highest stock speed supported on 875/865 and K8T800/nF3/SiS755 motherboards. The rated speed of both G. Skill TCCD and PQI 3200 Turbo.
2. 866FSB/DDR433 - a speed rating that we have used in testing other low-latency DDR400 memory.
3. 933FSB/DDR466 - a standard memory speed also specified as PC3700.
4. 1000FSB/DDR500 - a standard memory speed used in testing other high-speed memory and the rated speed of OCZ PC4000 Gold Rev. 2
5. 1066FSB/DDR533 - a standard memory speed included for comparison
6. Highest Stable Overclock - the highest settings that we could achieve with this memory and other memory that we have tested.

These are the same general settings used in benchmarking other DDR memory in the past year. DDR400, DDR500 and Highest Memory Speed have been used for all benchmarking. DDR433 and 466 were also used for testing other DDR400 2-2-2 modules, so we also ran benchmarks at these timings for comparisons. We also included test results at DDR533, since many TCCD memories have reached that speed and beyond.
