Performance System Memory: DDR3 Memory Read & Write

Performance System Memory: 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 1.3 profiles going. We test memory at a default rated 1600 MHz, as well as with the XMP profile activated at 2133 MHz.

Now with the regular memory at 1600 MHz versus AIDA memory tests we see good performance hovering at the 24-25K marker. With XMP enabled at 2133 MHz, the bandwidth rocks even harder.

Memory Write Test

We did the same with the memory write tests. The Write perf jumps to 33K when and the 2133 MHz XMP profile is enabled.

So if you like to go a little more crazy, purchase some nice compatible faster XMP ready memory and enable that XMP profile in the BIOS, then you get stuff like shown in the charts above with the 2133 MHz results (in the upper charts which is very impressive of course). Faster memory is relative though, your overall PC experience will not be incredibly faster, yet a few percent with memory intensive applications like say transcoding, or a CPU limited game. Every bit helps though.
