The Basics:
The OCZ Technology PC2-6400 Titanium EPP-Ready Dual Channel 2GB DDR2 Kit uses the XTC heatspreader found on other OCZ Technology Titanium series memory modules. Taking a close look at the heatspreaders I verified they were making full contact with the chips and did not find any gaps where the heatspreader had pulled away from the modules.
Each module includes a sticker on one side that details the model information and the basics of the memory's timings. The image above details that the part number is OCZ2T8002GK which is rated at PC2-6400 speed with 4-4-4-15-1T timings using EPP. The OCZ Technology web site also lists the non-EPP timings of 5-4-4-15-2T.
Testing:
To test the performance of the OCZ Technology PC2-6400 Titanium EPP-Ready Dual Channel DDR2, it was installed in a system with the following key components:
» AMD X2 4200 AM2 processor
» Asus M2N32-SLI Deluxe motherboard
» 2x eVGA 7900GTO video cards in SLI
» Tagan TurboJet 1100W power supply
» 2x 80 GB Hitachi Deskstar SATA 3 Gbps hard drive in RAID 0
» 1x 120 GB Seagate 7200.9 SATA 3 Gbps hard drive
Before I began any testing I verified the BIOS was reporting the correct default timings of 4-4-4-15 1T (CAS-TRCD-TRP-TRAS) @ 800MHz. The Asus BIOS was reporting the correct default settings, and I manually adjusted the power setting to 2.1V (which isn't actually necessary with EPP). They only other adjustment that had to be made to the BIOS was to enable the EPP option for easy overclocking.
Overclocking:
Before we get to benchmarking, let's see how well this kit can be overclocked. I am certainly no expert overclocker, and would expect more experienced overclockers to be capable of better results with ease. Additionally, different results can be expected depending on many factors such as default multiplier, cooling, temperature, CPU, and motherboard options (just to name a few).
Once EPP was enabled, the system over-rode the memory's default settings and automatically overclocked it to 1055MHz from the base speed of 800 MHz. This is similar to the speed of another memory kit to be used in this review, the OCZ Technology PC2-8500 Platinum SLI-Ready Dual Channel DDR2, which is rated for a default speed of 1066MHz.
As for the CPU (with a single video cardinstalled), I was able to perform a simple overclock by adjusting the CPU Frequency to 240MHz with an 11 multiplier. Changing the timings, multiplier, and HTT, I was able to get a maximum overclock of 257MHz.
Installing the second eVGA 7900GTO video card in SLI, I was able to overclock to a stable 245MHz, with instabilities at anything higher. Adjusting the HTT, multiplier, and timings did not provide any further benefit to overclocking.
