Tested and qualified to reach DDR3-1800 with ample overclocking capability and aggressive latencies, the OCZ PC3-14400 Platinum Edition is the flagship DDR3 part from the crew at OCZ. Each module is 100% hand-tested for quality assurance and compatibility and features a proprietary platinum-mirrored XTC (Xtreme Thermal Convection) heat spreader for the most effective heat dissipation.
At 1800MHz, the OCZ PC3-14400 modules are rated to run with 8-8-8 with 1.95V. The labels have the frequency and timings on it, but they left off the tRAS setting and the voltage. It would have been nice to see these timings on the box or on the label as it makes installation quicker.
OCZ doesn’t say what their SPD timings are, but CPU-Z showed that at 1333MHz they are 7-8-8 with 1.5V. Just like the Kingston kit, the OCZ kit does not offer XMP memory profiles, so the SPD Extension is left blank. In order to use this kit at it’s rated speeds, it will have to be manually set in the BIOS. This means the timings will need to be set to 8-8-8-24, the memory voltage increased to 1.95V, the front side bus (FSB) of the processor overclocked to 450MHz and the correct memory divider used to reach 1800MHz.
The Super Talent W1800UX2GP is an extreme performance 2GB kit of DDR3-1800 DIMMs that is part of the Super Talent Project X series. It has been tested as a matched pair of modules in a dual channel motherboard to ensure ultimate reliability, compatibility and performance on the latest Intel systems. The modules are clad in Super Talents custom black cast aluminum high-efficiency Project X heatspreader for optimum thermal performance. Project X employs an extreme cooling solution that offers double the surface area and 106% more aluminum mass than standard heat spreaders. Efficient cooling, as you all know by now, is essential to optimize speed and to preserve the life of the DIMM.
This module has been tested and is guaranteed to operate at 1800MHz at 7-7-7-21 latencies at 2.0volts. Each kit is hand tested as a matched pair on a dual channel Asus P5K3 Deluxe motherboard before getting shipped out the door in case you are wondering. The label on the Super Talent W1800UX2GP states partial timings and mentions nothing about what voltage is needed for the kit to operate correctly. We contacted Super Talent about this and was informed to run them at 1.9V, which is odd as the XMP settings default to 2.0V. It would be nice to have the label updated or at lease voltage information present on their corporate web site to help customers who are trying to install their kits.
Super Talent doesn’t say what their SPD timings are, but CPU-Z showed that at 1333MHz they are 9-10-10 with 1.5V. The XMP profiles were correctly set to 7-7-7-21 with 2.0V at 1800MHz. As previosuly mentioned, only the Corsair and Super Talent kits we are looking at today feature XMP memory profiles.
