want to buy FOUR quad socket xeons, must be E7 V4 for example xeon e7 8870 v4.

the CPU must have support for DDR3 ram (i am using a supermicro x10qbi mobo)

i would like to buy one quantity for testing in my system before I commit to buying the entire set of four

thanks!

I have 2x SuperMicro Quad CPU Chassis\Mobo + CPUs (4667 V3) if you are interested in those by chance :) Msg me.

There are a few E7-8880 v3 ebay listings at $125 shipped. Buy one then buy 3 more.

@angel_bee you might need to buy 2 to test - that's what I found in my testing with the X10QBI - I could not find a single CPU socket that worked for booting, but socket 1 + either socket 3 or 4 worked for me (I currently have 2x e7-8891 v4 with ddr3 in mine in socket 1&4 (I haven't had time to poke at it lately or find more/different CPUs))
Good luck!

hey thanks so much for the advice, actually your advice on the thread on xeon v3/v4s with x10qbi was extremely helpful too. this is still really new territory and i really appreciate any help that can (potentially) prevent me from wasting money :D

hey do you also know whether multiple engineering samples with different codes e.g. QK5U, QK6T etc... would they work? or would they be too different?

I bought 4x v2 CPUs for cheap to play and test with before I bought the v4 CPUs (which I kind of bought because they were cheap, but kind of regretting it now because I'd like to have four, and they tend to be expensive :rolleyes:)
I don't know about ES chips, but I did try mixing different production CPUs to no avail (which I expected)
Is there a reason you want v4 instead of the v3 CPUs? I've been thinking about trying to get some 8890 v3s if they come back down in price, but there is a premium on v4 CPUs right now.

v4s seem to have slight IPC increase over the v3. and i want to get something that's similar-ish to Xeon platinum system (which is what i'm currently borrowing right now), but not too far off in terms of single core performance. i feel like v3s might be too old? ...
