SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility. It should provide most of the information (including undocumented) you need to know about your hardware, software and other devices whether hardware or software. It works along the lines of other Windows utilities, however it tries to go beyond them and show you more of what's really going on. Giving the user the ability to draw comparisons at both a high and low-level. You can get information about the CPU, chipset, video adapter, ports, printers, sound card, memory, network, Windows internals, AGP, PCI, PCIe, ODBC Connections, USB2, 1394/Firewire, etc.
Sisoft Sandra offers two types of tests, un-buffered and buffered. Below are the test results.
The results clearly show that the higher the CPU:RAM ratio, the better the performance you get. 1:1 seems a little slow, so if you're thinking of doing any overclocking attempts, you should probably begin with 3:5 (DDR2 889).
Before this test packet was created there was no proper software for measuring vital system parameters such as CPU/Chipset/RAM providing steady and reliable (reproducible) test results and allowing for changing test parameters in a wide range.
Vital low-level system characteristics include latency and real RAM bandwidth, average/minimal latency of different cache levels and its associativity, real L1-L2 cache bandwidth and TLB levels specs. Besides, these aspects are usually not paid sufficient attention in product technical documentation (CPU or chipset). Such test suite, which combines a good deal of subsets aimed at measuring objective system characteristics, is a must have for estimating crucial objective platform parameters.
RightMark offers a variety of benchmarks, including both read and write performance for synthetic and performance tests:
With the DDR2 1128 setting, you get some very impressive results.
