Performance - DDR3 Memory read | write

Memory Read test

This first time we ran the memory test we could not believe our eyes really. So we ran it again and again. The results are subject to change, but you are looking at DDR3 memory running at 1333 MHz in dual-channel on the Sandy Bridge processors. The read memory bandwidth is near triple channel performance. And once you flick on an overclock and set that memory at 1600 MHz then you'll pass 19K read performance.

But if you think that is insane... check out write performance:

 

Memory Write test

So here we can observe write performance, we hover around 18GB/sec for 1333 MHz CAS9 in Dual-channel mode. And overclocked at 4.3 GHz / 1600 MHz memory... we pass 21K. Obviously there's no real way to verify if memory performance is indeed this good, but we tried a couple of tests with other software and all software suites show tremendous memory performance gains.

Here's an example of one of the test software's results, this is AIDA with the PC running at default settings. Now, on each run the numbers will change a little bit due to random occurrences, but each test we ran remains roughly at this level.
