PCSTATS Memory Test Methodology and benchmarks

PCSTATS tests DDR memory on AMD Athlon64 systems only because Intel has effectively made the transition to DDR2. Enthusiasts usually keep to the bleeding edge, so fast DDR memory is useless for the Intel overclocker looking for more juice.

On AMD test systems we're only interested in seeing how high we can go with the memory running 1:1, as running with other dividers puts the overclocking bottleneck elsewhere, not with the system memory. We usually run DDR RAM latency at 2-2-2-5, or the memory's tightest possible timings, as quick access is important to the CPU design. However in cases where memory is built to run at high speeds with lax memory timings, we will run the benchmark tests at the manufacturer specified timings. Not doing so would put high speed DIMMs at a disadvantage since the memory may not be designed to run at tighter memory timings.

As we move into the benchmarks a quick explanation is in order as to why the results will show minor performance gains due to the faster memory speeds we're testing. With previous platforms, increasing memory speed often meant also increasing the bus speed between the processor and memory. Since the memory controller is integrated into the Athlon64 processor, overclocking memory does not increase the speed of data moving to and from the processor any further, since there is no bus. To really get the most from your memory overclocking, you must also increase the CPU speed so it can handle the increased memory bandwidth. The reason why we do not do this during testing is because CPU speed will affect the benchmarks and that would not allow the results to be directly comparable to previous tests. By keeping the processor at approximately the same speed for all tests, we are seeing the real world benefit from the increased memory frequency alone.

Overclocking Athlon 64's is a bit different since there is no more bus between the memory and CPU. On your system, make sure you increase the speed of your processor so you can get the most out of both the memory and CPUs!

With that out of the way, let's get started with the benchmarks!

Winstone 2004 Source: Zdnet

Business Winstone 2004 runs real applications through a series of scripted activities and uses the time a PC takes to complete these activities to produce its performance scores.

Business Winstone 2004
Memory: Points Ranking
2x 512MB Patriot PEP5125600ELK PC5600 (200/400) 31.7
2x 512MB Corsair TwinX1024-3200XL PRO (200/400) 31.5
2x 512MB Centon GEMiNi PC3200 (200/400) 32.3
2x 1024MB OCZ PC4000 Gold (200/400) 32.5
2x 1024MB Corsair TwinX2048-4400 Pro (200/400) 32.7
2x 1024MB Corsair TwinX2048-4400 Pro (284/568) 34.7

The extra memory even at stock speeds does help out things here in Business Winstone 2004. Overclocking boosts overall performance very slightly.

Sandra is designed to test the theoretical power of a complete system as well as the individual components. The results are also purely theoretical and may not represent real world performance.

2x 1024MB Corsair TwinX2048-4400 Pro (284/568) 6941 6935

Who said you can't get good bandwidth numbers with a large amount of memory. ;-) At stock speeds the Corsair TwinX2048-4400 Pro has just as much bandwidth as the 1GB kit modules, overclocking almost allows the system to break 7K.
