Intel Xeon E7-2870 SLC3U 2.4GHz 30MB 10-Core LGA1567 CPU $30

[Boddy]

I spotted quite a few of these CPUs on EBay, some as low as $25.
I don't know if there is a major decommission or how hard it is to find motherboards or how expensive MBs are?

A bit older than E5-2670, maybe not as fast (but half the price), more level 2 & level 3 cache; but can be used in 2x CPU configuration and support up to 1TB ram.
(EDIT: Only 2 CPU configuration and 1TB ram!)

This seller has them for $30

Found this on Ebay:

Correct me if I'm wrong, but doesn't the 2 indicate dual CPU (1 QPI link). So it's a dual CPU for what can be quad CPU motherboards.

I'll agree, it's a good price though.

Nice find. But MB is missing Memory Risers.
Memory Risers look like to be hard to find.

Also, that motherboard probably won't work without the rest of the system. Quad CPU machines are pretty complicated for Dell/HP, I have an HP equivalent and it has the motherboard, PCI Express board, PCI Express extender, IO board, and memory modules. Also, usually specific power connectors.

You are correct only 2 CPUs on 2870's and only 1TB ram supported

It's very late here:

the E5-4870s are around $60
there are some on auction (but look a little rough)

It is an E7-2870 and not and 4870 so it should be 2 sockels maximum. Pricing on an complete hp systems with 4x4870 and tons of ram is about 700-1000 Euro currently in EU. But the cpu are quite power hungry and not really fast

yeah westmere gen E7.... please don't bother.

I had a quad E7-4870 box and my quad 61xx opteron box stomped all over it. subsequently a dual haswell stomps all over that box...

I'm running a 4 x E7-4870 system, and it's crazy how much heat it throws out the back, even when it's not doing anything.

Thanks @sthsep , @Patriot, and @sno.cn for your invaluable feedback!

Spec look good on paper. But I'm glad I did not bite the bullet and invested in such older technology,
when Haswell CPUs could do much more with less power.

Thanks again for your help!
