Although optimized for the C19 chipset, this memory was highly flexible and I had no trouble popping into three different mainboards without experiencing any compatibility issues. Corsair may not be as large as some of the memory behemoths, however; their products are always tested thoroughly prior to hitting the shelves.

We begin our test suites with SiSoftware Sandra 2005.SR3.



As another bandwidth test I've chosen Lavalys Everest Home Edition Memory bandwidth READ and Write tests.



For latency tests I've included both SuperPi v.1.40 running at 1M and once again LavalysEverest Home Edition Latency benchmark.



For a total system benchmark I've included Futuremark PCMark05.



Onto gaming tests, I've included both Futuremark 3DMark2001 and 3DMark05 on the graph below.



No benchmark suite would be complete without DOOM 3 Timedemo1 I ran the demo twice recording each result in 800x600.



Finally HardwareOC Far Cry Benchmark v1.4.1 is very demanding on physical memory with many devotees now updating their systems with at least 2GB of DDR2. I've been promoting the use of 2GB kits for over a year now and many are coming around to the prospect 1024MB of memory just doesn't cut it in a multitasking, video saturated world.



Conclusion

Corsair's Twin2X1024A-5400UL proves to be flexible, fast and easy to use. Whether you’re an Overclocker pushing the boundaries of DDR2 performance, a Gamer wanting tight latencies for that extra FPS, or the average end-user whom simply runs his/her memory at SPD, this memory fulfills. Running this memory at 850MHz was easy, and in fact I've been running it at that speed now for the last two weeks without a glitch. I would like to thank Vivian at Corsair whom has had the patience of a saint given my leaky H20 system and my propensity for breaking stuff.

Pros
+ Fast
+ Versatile timings
+ SPD runs to 850Hz at CL4-5-5-19
+ Manually runs to 850MHz at 4-4-4-14
+ Runs at Command Rate 1T
+ Compatible with a multitude of motherboards and chipsets
+ Future Proof

Cons
- None

Corsair Twin2x1024A-5400UL can be purchased through Newegg for $252 w/free FedEx 3-Day and OverclockersUK for $189.
