OCZ expands the Reaper series with the HPC tri-channel kit. This one runs at 1866 MHz and offers CL8 right out of the box. The heatspreader design with heatpipe cooling looks menacing, but will it manage to keep cool under pressure when we push the memory to the limit and reap some praise?

Awesome review as always DS. I love how these scale well as sometimes even good mfgs dimms don't scale well as you go higher. Awesome 1400mhz at Cl5, that is kick ass.

These are based on Elpida MNE-Hyper, so logicaly, they scale well with voltage. But it can have some disadvantages.. as you may already know. :D

Btw. I hope you increase VTT aswell, unless you want your IMC to die soon.. keep at least max difference of 0.5V between VTT and vDIMM.. or better 0.3V (should be fine forever). 1.5V VTT is fine on air, 1.7V under water or L2N/DICE.

Intel limited this cause of B rev. of i7.. which tend to die really fast if this rule of max 0.5V difference was broken.. Otherwise.. vDimm is quite safe as long as you keep it at least 0.5V from VTT.

Eg. VTT at 1.5V allows you to use memory up to 2V.. (tough I wouldn´t recommand more than 1.8V).

Altought I´m happy that you test on Bloodrage, this board capability for memory overclock are really more than average board can do.. so don´t expect same OC on other boards (maybe except DFi or eVGA´s high-end).

Nice review ofc.
