e5 and e7 confusion

[Marshal396]

Hi All

A few questions here really as looking into this seems to have raised more than answered. It started with trying to find something that would support the Z10PE-D16 WS needless to say i've come across the E5 2667 V4 which will suffice for this.

During my search I have stumbled upon an E7-4890 (http://ark.intel.com/products/75251/Intel-Xeon-Processor-E7-4890-v2-37_5M-Cache-2_80-GHz) now as far as I can see this is the older gen socket (Intel says FCLGA2011) so not the -3 version and interestingly not LGA1567 which i've read the e7 are supposed to be.

So the real question is WOULD a E7-4890 work in a 2011 board, lets say this just for example (http://b2b.gigabyte.com/products/product-page.aspx?pid=4158#ov) should the board support the e5 equivalent? or would it not work due to it needing to be registered in the motherboards bios or it having a higher TPW demand?

Many thanks for your help

E7-4xxx CPUs are quad socket CPUs. That one is actually a V2 revision CPU. It is also a 155W CPU. There probably aren't a lot of motherboards that support it. Intel doesn't even list any of their own motherboards for that CPU. But they do show compatiblity with C602J chipset.

Gigabyte lists the CPUs that are compatible with that motherboard --http://download.gigabyte.us/FileList/QVL/server_qvl_7pesh2_v1.0.pdf

Hi Kanewolf

This makes sense, thats said my interpretation was it can work with up to 4 cpus but not would not necessarily need 4, by that I mean it could work if only 2 sockets were avaliable and populated should the motherboard support it?

I'll mark that as the solution, just was confused as I read most e7 were LGA1567 and wanted to know why this was an exception of sorts and if it would work if not stated as compatible but the e5 cpus would if of the same gen/socket, would be nice to find some compatible boards as they seem to be rather cheap now.

Just out of curiosity if it supports the chipset C602J would that mean the e7 would work with the motherboard on that chipset or will it still need to be marked as compatible by the manufacturer?

Thanks again

The intel ARK -- http://ark.intel.com/ is the place for all data Intel. If you look at the page for the C602J chipset -- http://ark.intel.com/products/66243/Intel-BD82C602J-PCH and follow the compatible products link, you will see that a number of E5 and E7 CPUs are compatible with the C602J. I would always verify through the manufacturer's website that a motherboard had been tested successfully with a specific CPU before purchasing either.
