Kingston vs OCZ DDR2-800MHz Memory

Test Setup

• Synthetic Testing: Intel Core 2 Extreme X6800 (operating at 2.93GHz - 11x266); Inno3D 680i SLI motherboard; NVIDIA 7600GS Video Card, Seagate 7200.9 200GB 7200RPM SATA 3Gbps hard disk drive; OCZ GameXStream 700W power supply unit; Windows XP Professional Service Pack 2; DirectX 9.0c; NVIDIA Forceware 93.71 WHQL.
  
  
• Real World Testing: Intel Core 2 Extreme E6400 (operating at 2.13GHz - 8x266); Inno3D 680i SLI motherboard; NVIDIA 7600GS Video Card, Seagate 7200.9 200GB 7200RPM SATA 3Gbps hard disk drive; OCZ GameXStream 700W power supply unit; Windows XP Professional Service Pack 2; DirectX 9.0c; NVIDIA Forceware 93.71 WHQL.

We used Corsair's CM2X1024-6400Pro 2GB kit (5-5-5-12) as a PC6400 reference point during our testing.

PC6400 / 800FSB testing

We tested the memory at its stock speed of 800MHz, at both its rated timings and the fastest stable timings we could achieve with extra voltage.

Reducing the timings, the OCZ FlexXLC clearly performs the best, but also starts from a relatively low latency 4-4-4-15, whilst the 1GB kit of Kingston low latency HyperX nearly matches it at 3-3-3-9 it doesn't offer the same performance increase. The Kingston HyperX 2GB kit running at the stock timings of 5-5-5-15 fractionally out performs the other modules at stock timings, but when tightened to 4-3-3-12 doesn't perform that much faster. In comparison the Corsair Pro at 5-5-5-12 which reduces to a slower 4-4-4-11 out performs it.

Interestingly, despite the fact the OCZ FlexXLC runs at 3-3-3-9-18-2T, the Kingston HyperX low latency 1GB kit has a lower random latency, even though it's only capable of running 3-3-3-9-24-2T. However, the best stock performer is the OCZ despite the fact the Kingston low latencty 1GB kit sports lower tRAS timing.
