OCZ uses their signature XTC cooling heat spreaders on this series of memory. These are the simplest form of heat spreaders from OCZ, when you consider the likes of the Reapers, Blades and FLX XLC line up. All are taller and heavier than the XTC spreaders. Behind the XTC spreaders are chips capable of 8-8-8-24 timings at an incredible 1.65 volts.
We won't go into great detail as we have covered the XTC lineup many times here on Pro-Clockers, but you can not have XTC without the big Z in the middle of the heat spreader. The P/N stickers lets you know all you need to know about the modules, including the model number, timings and speed ratings.
