Tightening up DDR3

Kingston has announced it's new lineup of low(er) latency DDR3.  The timings available on DRR3 will take some getting used to, as even these tightly timed DIMMs look sloppy compared to high end DDR2, but the as the actual clockspeed increases, those timings won't seem so bad.  The modules AnandTech tested are rated at DDR3-1375 @ 7-7-7-20, and when they were clocked up to 1520 @ 8-8-8-22 they left Corsair's Dominators in the dust.

"With this scenario, imagine our surprise when Kingston asked us if we would like to review their first low-latency DDR3.

Where the competition was 9-9-9 at DDR3-1333 and 7-7-7- at DDR3 1066, Kingston specified their new DDR3 memory at 7-7-7

at 1333 and 6-6-6 at 1066. These were definitely some memory sticks we wanted to review.

If these numbers still seem high to you, you need to back up a bit for a larger perspective. While lower speed DDR2 can

have latencies as fast as 3, DDR3 starts at 800 and the boards we have seen only allow CAS latencies as low as 5. The CAS

range on better P35 boards is normally 5 to 10. Given this range of available latencies at higher speeds than DDR2, it is

clear the new Kingston KHX11000D3llK2/2G has found ways to provide the lowest latencies so far in DDR3."
