Page 5 of 6 Results: For testing the OCZ DDR2 PC2-6400 Platinum Enhanced Latency XTC Dual Channel Memory I used the following test setup: Motherboard: ASUS P5W DH Deluxe CPU: Core 2 Duo E6400 2.13 GHz (1066MHz) 2MB L2 Cache Socket 775 @ 3.2GHz PSU: PC Power & Cooling Silencer 750W Video Card: HIS X1900XTX Crossfire setup Hard Drives: 2 WD Raptor 74GB HDDs in RAID0 Drive: Plextor PX-755SA DVD±R/RW Drive Memory: OCZ DDR2 PC2-6400 ATI CrossFire™ Certified Edition Memory Below are the results at the default speed 800MHz DDR2 (400MHz).  Please note that in order to find the maximum stable overclock, I increased the memory voltage to 2.2 using a timing of 4-4-4-12. I started at the default speed of 800MHz DDR2 and slowly increased until I hit 940MHz. I found 910MHz DDR2 (470Hz) to be stable when both running Prime95 and games. I should also mention that using anything above 2.2 volts was not very stable. Even at default speeds using a voltage over 2.2 will result in instability. So remember to keep the voltage on this memory below 2.2 and everything should be A-Ok. Remember, the lower the memory timing the better. Sometimes a lower memory timing at a lower speed will be on par with memory at a higher speed using higher memory timings, so keep that in mind when overclocking memory. Please keep in mind that these overclocking results will vary from module to module and system to system.  Also note that like most other OCZ memory, this product comes with EVP or Extended Voltage Protection. This features allows overclockers to push this memory to 2.2V ± 5% without voiding the lifetime warranty. This perk is something that will give performance enthusiasts the freedom to push this memory to faster speeds. Additionally, this product is qualified to cas4 on ATI chipset motherboards. Other chipsets may need cas5 for the memory to run correctly. |
