In this day and age it's great to see manufacturers like OCZ optimising their RAM for particular chipsets, and the PC2-6400 Titanium EPP-Ready Dual Channel sticks are no different. This 2Gb kit is in fact optimised for Nvidia's nForce 590 SLI chipset. The way that OCZ achieved this was through their new EPP-Ready (Enhanced Performance Profiles) memory modules. Essentially, the module actually has two programmed speeds; one when run on an optimised board (NVidia 590 SLI) and another for other boards based on competing chipsets.
|OCZ PC2-6400 Titanium memory modules are programmed to boot at 800MHz DDR2 with supremely fast timings of 4-4-4 1T on on AM2 nForce 590 SLI platforms. Only motherboards equipped with the custom-designed BIOS, such as those designed for NVIDIA nForce 590 SLI MCPs, can detect the optimized SPD profiles and ensure the memory functions under the best possible conditions. Because the PC2-6400 Titanium modules are capable of accepting one command per clock cycle (1T), bus contention issues are solved and memory performance is increased by a considerable amount. |
Another specific feature that OCZ has increasingly evolved into their memory modules is E.V.P (Extended Voltage Protection). Essentially, E.V.P is:
|...a feature that allows performance enthusiasts to use a VDIMM of 2.3V ± 5% without invalidating their OCZ Lifetime Warranty.|
It's a nice touch that you can pump some more volts into these modules without voiding your lifetime warranty.
The PC2-6400 Titanium EPP-Ready Dual Channel modules utilise OCZ's patented XTC heatspreader. The XTC heatspreaders ensure that the thermal management of memory modules is promoted through greater airflow and by means of micro-convection throughout what is usually the dead air space inside conventional heatspreader designs. In this manner, build-up of heat is avoided and thermal dissipation of the memory components is offloaded more efficiently through the honeycomb design. At the same time, mechanical stability is maintained.
I have taken the liberty of throwing in a GSKILL module in order to illustrate the comparative difference between the heatspreaders. Hmmm, I wonder which will manage heat more efficiently?
After gently coercing the heatspreader off we can see the DDR2 RAM chips quite clearly. The XTC heatspreaders were stuck to the RAM chips using double sided thermal tape - extremely effective and very hard to remove.
The identification of these RAM chip numbers was extremely difficult. But, taking an educated guess, I would suggest that these are in fact re-badged ProMOS
chips on an Brain Power PCB. For those of you interested, the identification numbers were:
X42M120840L - 25
Installed, they look quite at home in my PC.
Due to the SPD identifying modules incorrectly from time to time, I have taken the liberty of disabling it. And yes it identified my Titanium modules as 5-6-6-15.
Now that we've gotten closer acquainted with our review subject, let's see how well they perform.
