Performance With SANDRA: 2-3-2-6 & 3-4-4-8


We began our testing with SiSoftware's SANDRA, the System ANalyzer, Diagnostic and Reporting Assistant. SANDRA consists of a set of information and diagnostic utilities that can provide a host of useful information about your hardware and operating system.  We ran SANDRA's Memory Bandwidth test on our AMD powered test bed with three different brands / types of memory installed.

Benchmark Notes: Our first test is with the widely popular SANDRA tool from SiSoftware. The scores we present here, and with the rest of our benchmarks for that matter, show the performance of our Corsair ram in a variety of settings. We first benchmarked the ram with an FSB speed of 200MHz, and we tightened the timings to 2-3-2-6 in order to get an apples to apples comparison with our Mushkin memory. Next, we overclocked the memory as far as we possibly could using the tight 2-3-2-6 timings. With our second set of benchmarks, we raised the FSB to the rated maximum FSB of 275MHz, and raised the timings to 3-4-4-8 2T accordingly. Our first set of numbers are with the memory at 275MHz 3-4-4-8 and ~2GHz CPU speed. We then raised the CPU Multiplier to 8.5 to obtain a CPU speed of 2.34GHz, as memory bandwidth is also dependant on CPU speed. This will give you a good idea of the importance of CPU speed in conjunction with memory.

With a close comparison to the Mushkin memory, there's hardly a difference in the test scores. However, once we raise the FSB, even with looser memory timings, the speed of our Corsair memory starts to show a bit more. Some users report being able to run their memory with a 1T rating, however we couldn't get our memory to run stable enough for our round of benchmarking at 3-4-4-8 1T.
