Kingston HyperX DDR2-800 2GB Memory Kit

Performance Testing : Intel Pentium-D Platform
For Intel based testing, our system consisted of an Asus P5WD2-E Premium motherboard, based on the Intel 975X chipset. The board officially supports DDR-800 memory speeds, and allows for manual timing and voltage adjustments. We paired the motherboard up with an Intel Pentium-D 940 dual-core processor and a GeForce 7800 GTX 256MB graphics card.

We first ran some tests comparing the Kingston HyperX DDR2-800 modules to "generic" DDR2-667 and DDR2-800 modules, both of which ran at CAS 5-5-5-15 latencies, in order to see how much the lower latencies of the HyperX modules help memory performance.

As we can see, when using an Intel Pentium-D processor, using the HyperX memory modules does not help performance greatly over "generic" modules. We see positive improvements in terms of latency, but our memory bandwidth numbers are virtually un-changed between modules.
