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.
