Memory Performance Testing

Sisoft; Sandra 2005 SR2a:

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. The chart was based off of the buffered bandwidth scores. 

Image Description

Results: The OCZ Platinum memory modules takes the lead in the first benchmark by just beating out the Mushkin eXtreme modules.  This makes perfect sense because the OCZ modules have the tighest timings of all the modules in our group at 4-3-3-8 timings.  Since the timings are identical on some modules the differences seen in the chart are a result of the different PCB’s and IC’s that each brand uses.  

Everest Version 2.20:

Everst 2.20  is a professional system information, diagnostics and benchmarking program for Win32 platforms. It extracts details of all components of the PC. It also tests the actual read and write speeds of your memory giving a fairly accurate look of true memory performance.

Image Description

Results: Everest 2.20 shows just over a 100MB/Sec difference in memory bandwidth for read speeds and nearly as much for write between the modules.  The Corsair XMS2 Pro modules take a beating on this benchmark, but the results were confirmed on numerous benchmarking days. Once again we see OCZ and Mushkin in the top two spots.

ScienceMark 2.0 Final:

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.

Image Description

Results: Sciencemark showed less than a 2% performance difference between the all the memory modules when we completed memory bandwidth testing.  No signifigant difference here and the race is still too close to call. OCZ’s modules came out first in all three of our bandwidth test!

Now let’s move on to some gaming benchmarks and Super Pi!
