Performance - DDR3 Memory read | write

Memory Read test

So for memory we had some good stuff to work with, Intel has a couple of certified partners for memory to get some sweet XMP profiles going. one of them is G.Skill with their newly revised RipjawsZ series memory, the 3d reincarnation of their DDR3 memory modules.

We received a nice 4x4Gb kit for quad channel setup, and when you OC or want a more easy way, flick on the XMP profile in the BIOS and it will clock in pre-defined at 1866 MHz for you.

Obviously we also had to peek at memory bandwidth performance. Now with he regular AIDA memory tests we see good performance, but it certainly did not double up, despite being in quad channel mode. Still the GSKILL RipjawsZ sticks at 2133 MHz manage to push nearly 20000 MB/sec which is fantastic. Once you start to overclock the performance rises nearly exponentially BTW.

Memory Write test

We did the same with the memory write tests. Again a bit average default results here. it totally changes once we measure with SiSoft Sandra though:

Sandra Memory Index

Here we make use of the Sandra Memory performance test, it gives us an index score of overall memory performance, and yeah .. there's no hiding from that. These are near silly numbers to observe as with 1866 MHz in quad channel we close in at 44 GB/sec, that's 44.000 MB/sec of bandwidth.
