MaxxMem2 PreView is a useful, free program to rate memory performance. It can be downloaded over here.
Again we see a good boost in performance when the Blackline memory was overclocked, except in the write test. It still can't match the performance of the 2133 MHz Redline memory, though.
They make excellent memory kits, bit expensive though compared to some at the same speeds
I bought a Mushkin kit a year ago and my system was never stable with the kit in. I have a very skilled friend who came around and worked out that one of the sticks was faulty. We had the kit replaced and the new one failed within a month. I had it replaced again.
The last one is working still, but I would have concerns over their quality control.
I would buy the redline memory, its much better grade for overclocking. this stuff is average. wouldnt touch it.
