Sandra - Synthetic Tests
SiSoftware's 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. Sandra provides similar level of information to Norton SI, Quarterdeck WinProbe/Manifest, etc. The Win32 version is 32-bit and comes in both ANSI (legacy for Windows 98/Me systems) and native Unicode (Windows NT4/200X/.Net) formats. The Win64 version is 64-bit and comes in native Unicode format.
Do note that all the SANDRA benchmarks are synthetic and thus may not tally with real-life performance. The latter stands for whatever your environment is, i.e. which applications you run with what amount of data and so on. It is up to you to decide whether what Sandra measures is what you want to measure.
Below you can find the scores of Sandra starting with memory performance:
It is really difficult to understand what we present to you. Interpreting data in the way we tested and what we can show you simply is hard to comprehend, especially with all the mathematic BIOS timings and dividers. Memory tweaking and overclocking is close to science.
You'll notice we use several memory kits at ranges from 1333 MHz up to a pretty wicked reaching level of an 2133MHz.
For our tests it's important to have Core i7 clock frequency and QPI the same throughout the tests. Unfortunately we did not have a divider for 2000 MHz for the G.Skill memory available in that exact configuration.
There was one for 2133 MHz, and since it's running stable on that frequency as well .. we simply opted to go that step higher instead of going downwards towards 1866 MHz. Yep - that's 2133 MHz right out of the box, that is called value for money. We also ran the G.Skill kit at 1600 MHz for comparison reasons.
We also included an OCZ kit at 1333 and 1600 MHz (JEDEC timings). Mind you, you can set these timings lower yourself (tweak it a little). Last but not least, a 6Gb kit .. Corsair Dominator kit. Delicious memory at massive costs. The Dominator memory is showing dominating performance. We opted to set CAS latency at 8-9-9-24 / 1.65V. it works 100% stable. That is awfully close though.
Everest Ultimate Edition
EVEREST offers accurate hardware information and diagnostics capabilities, including online features, memory benchmarks, hardware monitoring, and low-level hardware information. EVEREST Home Edition is optimized for Microsoft Windows XP, Vista and Windows Server 2003 operating systems.
With Everest we'll look at two different tests, as we'll measure both memory read and write performance. First up, memory read performance.
Check out the G.Skill memory clocked at 2133 MHz at a lovely CAS9. We actually pass 20000MB per second of bandwidth measured with Everest. That's crazy when you think about the fact a normal average age PC these days with DDR2 memory will reach 6000-8000 MB/sec.
Memory Write performance
Everest again, this time the results in write performance scale a little more intense. At 2133 MHz overclocked we reach nearly 17.5 GB/sec. That does not suck I can tell you. The trick is that CAS9 remains stable at 2133 MHz resulting into very impressive performance.
