As you can see from the Sandra results below, the Aeneon XTune DDR3-1600's performance was pretty good; at the stock 1600MHz it got 1150MB/sec more than low latency DDR3-1333, but 260MB less than lower latency 8-8-8-24 memory running at 1668MHz - as I would expect it to. Running overclocked to 1700MHz it beat the lower latency memory running at 1668MHz.
