Intel Xeon E5-1428L v3 

Released January, 2015
  • 2 GHz
  • Octa core

What makes Haswell-EP feel different is a slight change in strategy as to how the new core designs are binned according to their characteristics.

The single CPU option is cheaper, easier to manage and works better across the board.

Intel Haswell-EP Xeon 12 Core Review: E5-2650L V3 and E5-2690 V3

by Ian Cutress |
Similarly to the E5-2687W V3, the moment we hit a frequency the system does not like, it returns as a complete failed POST rather than a BSOD.
As part of this review we were able to source two E5-2650L V3 CPUs with a dual CPU motherboard and offer a more competitive analysis at 130-135W total TDP against the E5-2690 V3.
Although the seller knows what he is doing, it would be interesting to see where the founder finds himself an R3 motherboard.
DDR4 memory is supported upto 2133 Mhz, after which the memory controller starts to over clock itself.
