Is there any m-atx boards to take advantage of cheap Xeon E7 v2 processors?

I see this:

Intel Xeon E7-2890 V2 2.80GHz 15 Cores 37.5MB CPU LGA2011 SR1GV Tested Grade A 636946533502 | eBay

My case is only good for m-atx. Seems like too good of a bargain.

 

Nope.

Not a good deal for an E7 Xeon, either.

 

Because no motherboard available or not atx just eatx and bigger.

 

That's why .

 

mATX boards didn't exist in the mainstream for LGA2011. They are common place with LGA2011-3 boards (ie E5/E7 v3 models). There are some v2 compatible ATX boards, otherwise you could take a look at some of the proprietary formats and might find something that may fit with some case dremeling.

 

Xeon E7 is not 2011 or 2011-3 It's 2011-1 and they're not compatible. The only boards for the E7 line are proprietary. Even Supermicro doesn't have a board for E7 v2 CPUs aside from a single one that's to be used in multi-node chassis. Everything else winds up with memory risers and proprietary power connectors, so no chance of putting them in a regular case. There's a reason the CPUs go for so little. A few years ago it was the same story with E7 v1 CPUs (which are socket 1567).

 

How about "non-existing" Asus Rampage IV Gene - mATX with LGA 2011 supporting Xeons E5 V2 (and NVMe too).

 

I have one of these, it's great. E5-1650 v2 overclocked to 4.5 GHz on all cores.

 

So they do exist, not many popping on ebay for cheap...most $300 with some lucky auctions around $150.

 

um... that xeon is lga 1567 .so matx arent a thing for that motherboard as are used in quad socket system like like hp dl580 gen7
e5 xeons are lga 2011 like 2690 v2 or 2697 v2

 

ive seen on ark that they are lga 2011 but the require a c602j chipset but i dont see many

others have tried
Can a xeon e7 run on an x79 motherboard?

 

The problem lies with the socket. E7 v2 are designed for LGA2011-1 socket which is diffrent from the 2011-0 socket (that is used in the x79 motherboards). Simply put, the E7 v2 processors DO NOT FIT in anything you can find other than expensive proprietary motherboards with at least 2 sockets minimum (to my best knowledge) and those are hard to find.

 

For what its worth...

The Xeon "EX" series E7-xxxx V2 and V3 CPUs share the same socket (LGA 2011-1), and Intel designed them to have backward/forward compatibility. So, its possible that motherboards designed for Haswell EX (Xeon E7-xxxx V3) will also work with this CPU (assuming the vendor didn't lock the CPU selection). Broadwell EX (Xeon E7-xxxx V4) also used this socket, but I don't know if the compatibility extended to them when the process shrank from 22 to 14nm.

I doubt the Haswell EX (Xeon E7-xxxx V3) boards are any cheaper though.
