In a strange turn, we now see that the Kingston DDR3-1375 kit pulls into the lead, barely beating the Corsair kit. This is neat since the Kingston kit costs about half the price of the Corsair RAM. Corsair holds a close 2nd, followed by the Patriot set. Following the 1600 test, the Patriot set pulls into the lead, followed by the Corsair set then the PQI set.

We also see here that the Kingston DDR3-1375 kit is in 1st. Super Talent barely beats out the Kingston DDR3-1600 kit by 3 points. Again, the price comparison makes this quite interesting, as there is about a $100 difference in the kits. As we move to the 1600 test, we now see the Super Talent kit pull into the lead, with the Kingston 1600MHz kit trailing a close 2nd.

The memory latency test offers a lot closer result values than the previous tests, but we also see that lower numbers are better. The Kingston DDR3-1375 kit, Corsair DDR3-1600 kit, PQI DDR3-1600 kit, and Super Talent DDR3-1800 kit seem to be in the lead on this one, though there is only a 1ms difference. Now that we move on to the 1600 test, we see that the PQI doesn't even move! The rest of the sets speed up, but strangely the PQI lagged. Normally we wouldn't comment on the 1800 test, but you'll notice the time actually got worse for the Super Talent kit while operating at 1800MHz.
