Corsair DOMINATOR Twin2X2048-8888C4DF Memory Review
Corsair DOMINATOR Twin2X2048-8888C4DF Memory Review - PCSTATS
DDR2 memory has come a long way from its humble beginnings as just a few DRAM chips on a sliver of green PCB. Now, memory isn't memory unless it has extravagant cooling systems and reaches insane clock speeds.

Max OC Chart and Conclusions

It's great to see how individual memory stacks up against the competition under stock configurations, but we're also going to show how it compares when overclocked. With performance in mind, we're going to compare the maximum overclocked results of the various DDR-2 memory modules PCSTATS has tested in the past which are listed below. Remember, just because memory is clocked fast doesn't mean it's the best thing for a computer. Timings are also important, and getting the right ratio of both is the real key to performance based overclocking!

The Corsair DOMINATOR Twin2X2048-8888C4DF was retested on the new Asus P5N32-SLI Plus motherboard to see how it handles overclocking only and you can see quite a bit of a difference here. It's the fastest in low latency and loose latency testing by quite a bit and is the only memory that can hit 1300 MHz! Damn that's pretty darn fast wouldn't you say?

Are you extreme enough?

The enthusiast game of overclocking computer hardware has become a very mainstream affair. Manufacturers use high end computer hardware to impress us, to dazzle us with fast numbers, jaw dropping features, and luxury options that grab everyone's attention.

DDR-2 has been the watermark for how far memory can go, not just a commodity anymore, Corsair has introduced DDR2 parts that are worth coveting in their own right. So it takes a special kind of computer enthusiast to recognize that one must look past the flash, the verb-ladden names, and stare right into the heart of high speed low latency memory. The latter is quite important, and quite difficult to achieve. The 2GB Corsair DOMINATOR Twin2X2048-8888C4DF kit is the companies current flagship DDR-2 memory part.

The PC2-8888 DOMINATOR memory is capable of running at DDR2-1111 speeds with tight 4-4-4-12 CAS Latency memory timings. Of course with a retail price of $717 CDN ($610 US, £313 GBP) for this 2GB set of DDR-2... well, it's darn expensive. It's not lost on PCSTATS that high end memory of this calibre costs as much as a mainstream PC.

The Corsair DOMINATOR Twin2X2048-8888C4DF memory is obviously fast and with a stock recommended voltage of 2.4V, gets pretty hot. To combat the extra heat Corsair has totally redesigned the memory heatspreader for greater efficiency. It has also bundled in a unique DIMM fan that clips onto the memory slots for additional cooling.

Rest assured, if your PC system is equipped with Corsair's DOMINATOR Twin2X2048-8888C4DF memory, you're not going to be running it stock. At its DDR2-1111 rated speed with 4-4-4-12 timings, the memory is smoking fast, and really built with nForce 680i based motherboards in mind. You'll also need a quick processor, and a good videocard to get the most out of your system - but as long as this flag ship memory is paired with flag ship computer parts, it should be smooth sailing.

With tight 4-4-4-12 memory timings, the Corsair DOMINATOR Twin2X2048-8888C4DF memory was able to hit an amazing 1244 MHz in PCSTATS' overclocking session. Lowering the memory timings did not yield a higher speed, though perhaps it was the ECS PN2 SLI2+ that was tapped out... We really can't say.

Traditionally overclocking only the memory does not garner much of a performance boost, but that was not the case with the Corsair DOMINATOR Twin2X2048-8888C4DF. Running at 1244 MHz with 4-4-4-12 timings gave a nice boost to gaming framerates. Now, just imagine what could result when running this memory in conjunction with a fast system overclock!?

There's little doubt that the Corsair DOMINATOR Twin2X2048-8888C4DF is fast (and it is), but its high premium puts it out of range of everyone except the most dedicated computer enthusiasts. If you can afford the DOMINATOR PC2-8888 C4 modules you'll be happy. If you can't, well, you'll just have to make due.


Since PCSTATS moved the memory test platform over to the Asus P5N32 SLI-Plus motherboard, we retested the Corsair DOMINATOR Twin2X2048-8888C4DF memory and it's even better than we thought. On the new motheboard the Corsair memory with tight 4-4-4-12 timings was able to reach 1260 MHz! Loosening up the timings to 5-5-5-15 allowed the memory to reach the 1300 MHz mark which is a pretty big milestone for DDR2 memory!
