After last month’s test of top-notch Kingston HyperX modules declared to 2333 and 2400 MHz, respectively, we’ve received similar Geil and Patriot modules for testing. Both are dual-channel kits of 2x2 GB, best compatible with Intel Core i5 and i7 CPUs, at a voltage of 1.65 V. Specifications for both tested kits are largely the same. Geil is declared to DDR3-2200 CL9-10-9-28, while Patriot has declared their modules as DDR3-2250 CL9-9-9-27. It’s clear that for RAM modules with clocks this high, it’s best to have an appropriate motherboard that has a high memory multiplier (preferably 12x), since the RAM memory clock is the result of BCLK and memory multiplier.

Both kits come equipped with attractive coolers, which doesn’t come across as a surprise, as both memory modules belong to the high-end. Geil has opted for a more straightforward cooler design compared to Patriot, but we couldn’t escape the feeling that the cooler should have been better tightened. The coolers themselves are a bit large, yet stuck to the memory modules by a layer of thermal tape on each side, nothing more. This may be standard procedure, but we believe that it would’ve been much better had they used a few screws instead. Patriot is using the same method, but their coolers are smaller and therefore look more compact. Sector 5 generally means voltages of 1.65-1.70 V, but just like with Geil EVOTWO, we’ve been strictly sticking to the Intel-specified maximum of 1.65 V. Within the test itself, we were running at default latencies for each module - since these are CL9 modules, we believe that “relaxing” the modules to CL10 wouldn’t bring any performance improvements, with a marginally higher overclock.
