Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance. Higher numbers represent better performance.

SiSoft Sandra 2003 Benchmark Results
	Memory Benchmark (FSB/Memory)
	AMD/ALU
1.	Integer ALU - 2x 256MB Corsair XMS3500 (166/333 MHz)	2581 MB/s
2.	Integer ALU - 2x 256MB HyperX PC3500 (166/333 MHz)	2580 MB/s
3.	Integer ALU - 2x 256MB HyperX PC3500 (216/432 MHz)	3319 MB/s
	AMD/FPU
1.	Float FPU - 2x 256MB Corsair XMS3500 (166/333 MHz)	2449 MB/s
2.	Float FPU - 2x 256MB HyperX PC3500 (166/333 MHz)	2476MB/s
3.	Float FPU - 2x 256MB HyperX PC3500 (216/432 MHz)	3112 MB/s

It's not surprising that at stock speeds the Corsair XMS3500 and Kingston HyperX 3500 have approximately the same bandwidth. Overclocking boosts bandwidth nicely.

PCMark 2002	Source: MadOnion

PCMark is a new benchmark from our pals at MadOnion which a whole system benchmark. It can be used on desktop PC's, Laptops and even Workstations and tests everyday computing from home to office usage. PCMark specifically stresses the CPU, memory subsystem, graphics subsystem, hard drives, WindowsXP GUI (if WinXP is used), video performance and even laptop batteries. This benchmark was released March 12, 2002 and can be downloaded from Madonion if you would like to give it a test run on your computer for comparisons sake...

3.	2x 256MB HyperX PC3500 (216/432 MHz)	6722

Like Sandra, PCMark can't seem to differentiate between the two DIMM's at stock speeds.
