LGA-2011 RAM Speeds

Does anybody have real world experience with LGA-2011 platform. Can confirm what speeds at table are correct?

Module Type (No Mixing in a Server) Module Ranks 1 DIMM per Channel (1 DPC) 2 DIMMs per Channel (2 DPC) 3 DIMMs per Channel (3 DPC)
DDR3 32GB or 64GB RDIMM Quad Rank 1600 MHz (1.5V) / 1333 MHz (1.35V) Xeon E5 800 MHz (1.5V) X
DDR3 32GB or 64GB Load Reduced DIMM (LRDIMM) Quad Rank 1333 MHz (1.5V) 1333 MHz (1.5V) 1066 MHz (1.5V) / 800 MHz (1.35V)

* Xeon E5 series processors can support up to DDR3-1600 at 1.5V or DDR3L-1333 at 1.35V. (Single, Dual, Quad Rank)
* Xeon E5 v2 series processors can support up to DDR3-1866 at 1.5V or DDR3L-1600 at 1.35V. (Single, Dual, Quad??? Rank)
* Xeon E5 series processors: Up to two RDIMMs per channel or 2DPC (eight modules per processor in quad-channel configuration) Note: In fully loaded configurations on servers that provide twelve memory sockets per processor, Xeon E5 series processors will run the memory at 1066 MHz 1.5V. (Single, Dual Rank)
* Xeon E5 v2 series processors: Up to one DDR3-1866 RDIMM per channel, or 1DPC (four modules per processor in quad or triple-channel configuration). Up to two DDR3-1600 RDIMMs, or 2DPC (eight modules per processor in quad or triple-channel configuration). Note: In fully loaded configurations on servers that provide twelve memory sockets per processor, Xeon E5 v2 series processors will run the memory at 1066MHz 1.5V / 800MHz 1.35V. (Single, Dual Rank)

Is it possible to overclock to 1866 MHz in 1 DPC and 1600 MHz - 2 DPC? And what crazy speeds someone got on 3 DPC!

if the chipset is not X79 (real X79 or some chinese board that unlocked the mobo since some LGA 2011 mobo do use H67 and other chipsets, called (frankensteined mobo)), then you’re up to the motherboard itself to have the capability for manual OC. Sometimes they could only max the clock at 1866 at Ivy, or 1600 at sandy, since it’s their max speed (not an OC but running the max spec’d memory speed).

Also OCing server ram is pretty much reducing the means of ECC, if you do use it. But hey, it’s trials and error you should try it yourself.
