DDR2-675 - A High Speed Update from Corsair and Kingston

Article Index

Overclocked Results


For our last batch of tests, we set each kit to run with their SPD timings, and raised the front side bus on the Asus P5WD2 Premium as high as possible.  As we've seen in the past, we appear to be somewhat limited with overclocking our Pentium 4 550 on this motherboard.  The ceiling appears to be about 239MHz for the FSB, resulting in our CPU running at 4.06GHz and the memory at 798MHz effective.  With speed and timings on the same level, we should expect similar performance between the kits.  As with the Low Latency testing, voltages were raised 0.1V for each kit, so that the Kingston modules were running at 2.0V and Corsair's kit at 2.2V.

Performance Comparison with SiSoft SANDRA 2004
Raw Bandiwdth


The results are what we predicted.  Performance of both kits are right on par with each other, with negligible amounts separating the Corsair kit from Kingston's.  Overclocking the system gave us an additional 500-600 points over the original Sandra scores.

Performance Comparison with PCMark04
Overall Memory Score

The overclocked PCMark04 results were exactly on the money; both kits came in at 6212 points.  As expected, overclocking had a huge effect on performance, increasing scores by nearly 700 points for both sets of memory.  This comes out to over a 12 percent increase in bandwidth.

In-Game Performance Comparisons With Unreal Tournament 2004
System Memory Affects Framerates?  You Bet!

Unreal Tournament 2004 benefitted greatly by overclocking the systems, as frame rates jumped nearly 15 frames per second for both kits.  The Corsair XMS2 memory slightly lead Kingston's HyperX modules, but the difference between the two is well within standard margins of error.
