Bandwidth Testing - 5400UL

In the following tests, we perform some memory bandwidth measurements to determine the throughput of the modules. The numbers themselves aren't very practical except for purposes of comparing different RAM.



*Kingston @ 533 MHz, 4-4-4-12


In SiSoft Sandra 2005, we see a surprise. The older Kingston RAM actually performs extremely well compared to the 4-4-4-12 timings on the Corsair 5400UL. At 533 MHz, Kingston matches the 5400UL's results of 667 MHz 4-4-4-12.


A bit of an oddity though, the results at 533MHz 4-4-4-12 on the 5400UL show it being slower than 5-5-5-15. This anomaly shows up again in the Everest test (below).



*Kingston @ 533 MHz, 4-4-4-12



*Kingston @ 533 MHz, 4-4-4-12


With reading and writing, the Everest test shows all results tightly clustered. The Corsair 5400UL appears to excel at read performance, while the Kingston shows strong write performance.

The latency test above is a good summary of the memory tests prior: the modern day module (Corsair) does not really have much to boast about except at lower memory timings.
