Sisoft Sandra 2005 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 in memory bandwidth.
Results: A slight difference in bandwidth is observed when testing the buffered memory, but a more significant difference is noted when looking at the unbuffered data throughput. Going from loose timings of 4-4-4 to 3-2-2 increased the unbuffered score by almost 200MB/s. Corsair’s 5400UL running the DDR2-800 divider at the same front side bus showed 500MB/s more throughput! Without any FSB changes we were able to increase or unbuffered bandwidth by 13 percent from our starting point.
Science Mark 2.0 is an attempt to put the truth behind benchmarking. In an attempt to model real world demands and performance, ScienceMark 2.0 is a suite of high-performance benchmarks that realistically stress system performance without architectural bias. All of our testing was completed on the 32 Bit Final benchmark version that is dated March 21st 2005.
Results: Sciencemark likes the tighter timings a bit, but really loves the additional bandwidth offered when running the Corsair XMS2 5400UL modules at 800MHz with 4-2-2-8 timings.
Now let’s move on to some gaming benchmarks and Super Pi!
