Kingston has designed and manufactured another winner in their HyperX PC2 5400. The memory has been running trouble free for almost a month now, and is most impressive in its ability to run at only 1.80V. While most DDR2 667 requires 1.90V default, Kingston is the only memory I've tested which didn't require the additional voltage.

This reflects Kingston's use of high-quality IC's, and astute engineering. Many have been apprehensive about the PCIe and DDR2 route. Personally I feel it's the future and it has arrived early. The BGA technology has many advantages over its predecessor including higher speeds, lower voltage requirements, cooler running and excellent overclockability.

Recently I let a friend borrow my 3.0E for Socket-478, and in a phase-change system the processor ran completely stable at 4.33GHz. This current P4 530 easily boots into 4GHz and runs stable at 3.9GHz with a minimal Vcore increase. Unfortunately I believe the SATA controller may be the hurdle to move beyond 3.9GHz. At these speeds I haven't even begun to exploit the full potential of DDR2. If you’re considering this standard and looking for a kit of DDR2, I must profess Kingston is offering a highly competitive product to the market. Following in the HyperX tradition of high performance, high speed, at a low price, $155 for 512Mb at Newegg. This makes the Kingston HyperX PC2-5400 less expensive then the fastest DDR on the market and it's running faster at 675MHz!
