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.

One of the memory specialists offering XMP optimized memory DIMMS is GSKILL with their Ares series memory, their memory can be stock clocked at 2400 MHz. We received a DIMM dual-channel kit optimized for Z87 we use two bars. And what you are about to see is quite staggering in terms of memory bandwidth. For everything that you see below, we use either default BIOS settings, and when overclocked simply flicked the XMP profile in the BIOS to on. It's that simple.

Now with the regular memory at 1600 MHz versus AIDA memory tests we already see extraordinary good performance hovering at the 23-25K marker. Unusually high to be honest, but hey... these are the numbers, we write them down as measured. Also check out the memory performance at 2400 MHz, now there the CPU was overclocked to 4800 MHz though.

Memory Write Test

We did the same with the memory write tests. Amazing default 1600 Mhz performance. But once we activate the XMP profile the write perf jumped to 37K when the system is overclocked to 4800 MHz (and the XMP profile enabled). 37K MB/s on dual-channel writes, helloooow.

Above - Default clock frequency on CPU / 1600 Mhz on DDR3

Above - CPU overclocked to 4800 MHz + Memory XMP @ 2400 MHz for DDR3 - Humanahumana !

So if you like to go a little more crazy, once you overclock and enable an XMP profile (should you have compatible memory) then you get stuff like shown in the charts above with the 2133 2400 MHz results (in the upper charts which is very impressive of course).
