As you can well imagine – there isn’t a great deal of headroom with a DDR3 kit that has a frequency of 2133MHz at 11-11-11-27 but try we must. Pushing this kit proved very hard indeed but this is to be expected, bearing in mind the calibre and specifications. Trying to nudge the frequency up to 2400MHz at stock was nigh on impossible, as indeed was 2400MHz with looser timings – 11-12-11-30 @ 1.65v. We did get a boot beyond POST and managed to see the Windows 7 logo but this was as far as was possible.

Establishing that a frequency overclock was not on the cards I decided to lower the latencies at stock (2133MHz) to ascertain if this can be improved upon at all. 9-10-9-30 did boot into Windows but was found to be unstable so I decided to try 10-11-10-30 which just like the previous settings; did boot, but this time was stable. I’m sure with some advanced tweaking and different configurations better results may well be possible.

As a result, we shall be testing this kit with just the stock settings configured 2133MHz – 11-11-11-27 at 1.5v.
