Kingston HyperX Memory Modules
Two gigabyte memory kits form Kingston, which can be programmed to reduce latency and give better performance
Saturday, November 04, 2006
We have two HyperX series RAMs from Kingston-one being a PC2-8000 CL5
(KHX8000D2K2/2G) 1000 MHz and second PC2-6400 CL4 (KHX6400D2LLK2/2G) 800 MHz.
These DDR2 DIMMs provide lower latency at high speed. Latency is amount of clock
cycles
utilized for read/write requests to complete. The lower the latency, the better
the performance.
Both of these RAM modules come in a 2 GB pair kit with 1 GB on each module
These modules have SPD (Serial Presence Detect) programmed to JEDEC (Joint
Electron Device Engineering Council) standard latency of 5-5-5-15 working at 1.8
V on 800 MHz for PC2-8000 and 667 MHz for PC2-6400.

Both memory modules support dual channel. We ran the memory test suite of
PCMark 2005 benchmark, which runs a series of read, write, copy and latency
tests with varying loads of 4 KB to 16 MB. We used a Core 2 Extreme processor on
an ECS PX1 Extreme motherboard to test it, which let us change the SPD setting
to manual configuration and also change latency parameters.
With the PC2-6400, we could clock to 4-4-4-12 at 667 MHz and 2.0 V-a
setting at which it performed smoothly and better than normal PC2-4200 533 MHz
RAM available in the market. The difference is significant as the 533MHz RAM
showed a score of 5601 PCMarks compared to 5921 PCMarks with the Kingston
PC2-6400 (5.7% rise in performance). Our test system did not boot with the RAM
clocked at 800 MHz, contrary to Kingston's claims that it works fine at this
setting. The PC2-8000 modules rated is 5-5-5-15 on 800 MHz at 1.8 V but above
that it went up to a lower latency speed of 4-4-4-12 at 800 MHz and 2.2 V
showing better performance at 5986 PCMarks compared to others and 5934 PCMarks
of its own at default conditions.
Bottom Line: A good buy for extreme gamers who can afford the
exhorbitant price.
