It's great to see how individual memory stacks up against one another under stock configuration, but we're also going to show how they stack up to each other when overclocked. The results are listed below for some of the recent memory to cross PCSTATS' test bench. All memory was tested at its most lax timings as well as its most aggressive. In terms of best overall overclocking performance, PCStats currently gives more weight to the combination of moderately high speeds and low latencies (2-2-2-5) than high speeds at the expense of latency timings.

Higher density DIMMs tend to be more difficult to overclock than 512MB modules. The Corsair TwinX2048-4000PT memory does well here relative to other 1GB modules we have tested. If you're a hardcore gamer, 2GB of memory is certainly looking like the way of the future, and its nice to see that there are options.

Conclusions

With games like Battlefield 2 demanding upwards of 600-800MB of system memory, that leaves very little for the OS and other applications that might be running in the background. This is generally why 2GB RAM modules show such a lead in this benchmark. If you would like to test your system with Battlefield 2, you can learn how to benchmark it here.

At 200 MHz the dual channel Corsair TwinX1024-4000PT DDR memory modules are able to run with moderately tight 2.5-3-3-6 memory timings. If you're an overclocker though, the memory is rated to run at 250 MHz with 3-4-4-8 timings as long as the supporting hardware is capable. The units we tested had no problems achieving a speed of 255 MHz with tighter timings, and 290 MHz with default timings (3-4-4-8) in our labs.

	experts tip: dominant overclocking modules
	dual channel ddr memory overclocking on athlon64 platforms can become a little tricky at times because there is generally always one memory module that is stronger at overclocking than the other. to find out which memory module is the dominant overclocker in a pair of dual channel ddr, do the usual memory/timing tests with each individual stick alone, in single channel mode. note which module overclocks less, and when running in a dual channel configuration place that module in the dimm slot closest to the processor. rumor has it that the memory channel closest to the processor allegedly handles the weaker overcloking memory better than the outer slot. does this work for you? please let us know in the PCStats forums.

With applications and games using up more system resources, the transition towards 2GB of system memory is upon us. For enthusiasts, memory like the Corsair TwinX2048-400PT just makes that move easier. Of course enthusiasts who want the best always have to pay a price premium and with a retail price of $276 CDN ($230 US), the memory is priced a bit higher than generic DDR memory.

Judging by the results we've seen here though, these modules are a good choice for anyone looking to make the 2GB transition, but who still want to overclock their memory for that 'extra' performance edge.
