Memory, Hard Drive, Power Supply, Coolers
The following components are outside the scope of comparison here, but still very important to the results we're generating. We don’t want to limit our system with too little memory, a slow hard drive, a flaky power supply, or high temperatures. So, we’ve gathered an assortment of complementary hardware to help address our needs throughout this series.
Special thanks to Corsair, Western Digital, and Xigmatek for arranging the hardware needed to make this entire series possible.
Corsair Dominator TR3X6G1600C8D
This 6GB triple-channel kit of Corsair Dominator memory is rated DDR3-1600 and CL 8-8-8-24 timings at 1.65V. Corsair backs these modules with a lifetime warranty and uses DHX (Dual-path Heat Xchange) technology to keep them cool.
We’ll be utilizing either two or three sticks of this high-performance memory in each DDR3 platform tested, depending on whether the setup in question employs a dual- or triple-channel controller.
Corsair Dominator TWIN2X4096-8500C5DF G
For our DDR2 platforms, we’ll use a 4GB dual-channel kit of Corsair Dominator memory, rated DDR2-1066 and CL 5-5-5-15 2T timings at 2.1V. This kit is also cooled by DHX technology and backed by Corsair’s lifetime warranty.
Western Digital Caviar Black WD6401AALS
The Western Digital Caviar Black 640GB hard drive offers gamers a good blend of capacity, performance, and affordability.
This 7,200 RPM, SATA 3 Gb/s drive has dual processors, 32MB cache, and is backed by a five year warranty. Bear in mind that using an SSD instead of a mechanical drive like this one will almost certainly improve level load times, but it's less likely to affect your actual in-game performance.
Corsair CMPSU-850HX 850W
The right combination of motherboard, processor, memory, and graphics cards means little without a quality power supply unit capable of providing reliable, clean voltage to our components.
Considering the overclocking desires and multi-GPU configurations that you'll see later in the series, we chose an 850W unit from Corsair. The modular Corsair CMPSU-850HX has a single 70A, +12V rail, six 6+2 pin PCIe power connectors, a seven year warranty, 80 PLUS Gold efficiency certification, and a 140mm temperature-controlled fan.
Xigmatek HDT-S1283 & Dark Knight-S1283V
We're utilizing Xigmatek’s HDT-S1283 to cool our Socket AM3 and 775 processors, and the LGA 1366-compatible Dark Knight-S1283V to keep the Core i7-920 running cool. On both heatsinks, Xigmatek uses its HDT (Heatpipe Direct Touch) system for thermal transfer and a PWM-controlled 120mm fan, with rubber mounts for quiet operation.
