Package and Modules
OCZ have always done a good package for its memory modules. Usually placing them in a plastic blister that can be hung from display hooks at a retailer's shelf; the Reaper edition is no different. Reaper edition uses a gold and black packaging with the ID tag on the front showing you just what the memory is rated at and what speeds it does.
The back of the package gives you some more info on the modules, some marketing hype as well as showing you how in theory the memory heatsink unit that OCZ supplies on the Reaper works.
The Reaper HPC edition modules from OCZ are a 1GB dual channel pack (you can also buy 2GB packs), which means you get a pair of 512MB memory modules rated to run at 575MHz with a voltage of 2.3v - and yes, that voltage is definitely needed to get the modules running at this speed. They are protected by OCZ's extended voltage protection warranty up to 2.35v, but after that, you are no longer covered. As far as the timings are concerned, the modules come from OCZ designed to run at 5-5-5-18 at their full 575MHz and at 800MHz DDR we managed to lower this down to 4-4-5-18 without any problems at default voltage of 1.8v, which is not too shabby at all.
OCZ has pushed the envelope with the Reaper HPC modules. The FlexXLC was designed with water cooling in mind, and was actually quite a good series of modules. If you are unable or unwilling to run water though your precious system, OCZ has you covered. Reaper has a large heatsink and heatpipe arrangement on the top of the modules designed to draw away heat from the memory chips to its heatsink that is separate to the memory, this is supposed to give the memory a much greater surface area to dissipate the heat, allowing more air from the case fans to cool the modules down much more affectively than traditional heat sink arrangements on RAM modules.
