Hello Everyone,

I work at UCLA and we recently came into some Intel Xeon E7-8893 v2's through a chip donation. I'm looking to buy motherboards with at least a dual CPU configuration, and given it's a university, the lower the cost the better (trying to see if I can find anything below or around $500).

I've been looking far and wide for motherboards that support the processor without much luck. I've found the SuperMicro X10QBi and a couple other from SuperMicro but further investigation suggests they are very expensive motherboards.

Here is the question I have: Since these chips have FCLGA2011 (aka LGA2011) type sockets, would any motherboard with such a socket support and the right TDP support (155W in the case of these chips) work, or do the motherboards specifically need to support these chips?

I ask this because just about every motherboard I have found with the supported socket and TDP only list Xeon E5's as supported.

Thanks in advance for any help.

Hi there

Those are rather high end server chips that you have there and typically you're not going to find desktop class motherboards that support them. You will have to look at server boards, especially since you want to run a dual cpu configuration.
Sounds like you will have to put out for a motherboard donation as well :)

Hi Petrossa,

Thanks for the answer. I guessed I wouldn't find any desktop class motherboards (especially since I didn't find any online) for these chips. However, even among the server motherboards, ones that specifically list these chips as supported are very few.

I have come across server motherboards that have dual LGA2011 sockets, 160W TDP and Intel C602 chipset. Those same specs appear on motherboards specifically listing support for these chips (except they have 4 sockets instead of 2). That's what's got me thinking if I could use those cheaper server motherboards which do not specifically list support for the E-7's (they mention support for E5's) seen as how they are spec'd similarly to the ones that do list the support.

You wrote, " I've found the SuperMicro X10QBi that support the processor". That is wrong, no support for E7-8800 v2 family CPUs. Those CPUs are about $7000 each and are not v3.

Key Features (X10QBi)
1. Quad socket R1 (LGA 2011) supports
Intel® Xeon® processor E7-8800 v3 /
E7-4800 v3 family (18-Core), w/ QPI
up to 9.6 GT/s

The X10DBT-T supports those CPUs but I see that it is being sold in Super Servers and barebones systems. Maybe SuperMicro sales rep might help.

Hi Calvin,

Sorry for the late reply, been busy. Thanks for correcting me, hadn't spotted the "v3" at the end there.

However that still doesn't my question. Given the right sockets, TDP ratings and chipsets, would there be any reason a motherboard doesn't support the processors even if they are not explicitly listed as supported?
