The Kingston ultra low-latency PC3 1375MHz DDR3 HyperX memory modules have shown that lower CAS latencies deliver better performance in our benchmark testing. While other memory companies have been aiming to reach higher clock frequencies, Kingston has been busy working on screening Elpida memory ICs to offer tighter timings and it seems to have paid off as they are the only ones with CL5 memory at PC3-10666 or PC3-11000 speeds.
Overclocking on the Kingston ultra low-latency PC3-11000 memory kit brought back a sense of déjà vu, as the module characteristics are nearly identical as their low-latency kit. Both kits overclocked just shy of 1500MHz, which can be accredited to the Elpida memory ICs that are limiting the overclocking. By reaching 1472MHz we were able to get an extra 97MHz or 7% more out of our kit in terms of frequency. When cranking up the front side bus to 460MHz on our Intel Core 2 Duo E6750 processor the true potential of this memory kit was seen!
When it comes to pricing and availability one better be sitting down as the 2GB kit that we tested today will set you back $716 plus shipping. The Kingston HyperX PC3-11000 CL7 memory kit runs $452 with free shipping, which means the CL5 kit is $264 more expensive although it is without a doubt the fastest kit on the market today be it DDR3 1333MHz or 1375MHz. The extra cost is due mostly to the increased screening and the fact that the yields on these modules can’t be that great.
Pricing aside, these modules are stable, offer tight timings and are faster than what competing companies have brought to market at this speed grade. The benchmarks show that the Kingston HyperX PC3-11000 kits at CL5 and CL7 timings out performed the rest of the bunch and have shown critics that the HyperX line is still a leader in the enthusiast market today!
Legit Bottom Line: The Kingston 2GB ultra low-latency DDR3 1375MHz HyperX memory kit offers tight timings that other kits just can’t match and as a result are the fastest modules on the market at PC3-10666 or PC3-11000 speed grades.
