xeon naming scheme and socket/MB type...

[wildpig1234]

Hope I am not the only one very confused by the naming scheme, but I just hope someone can fill me in.

So you have:

e3-1xxx: 1 cpu config
e5-1xxx: 1 cpu config
e5-2xxx: 1 or 2 cpu config
e5-4xxx: 1 or 2 or 4 cpu config
e7-2xxx: 1 or 2 cpu config
e7-4xxx: 1 or 2 or 4 cpu config
e7-8xxx: 1 or 2 or 4 or 8 cpu config

So far, are all the above correctly stated?

now, please tell me about the specific MB needed for each. i.e. can every single one of the above run as 1 cpu in any 2011 MB (so you can have e7-8xxx running on x79 MB) and inversely you can run one e3-1xxx on a 8 cpu MB if you want?

what is the difference between e5-2xxx, e5-4xxx and e7-2xxx, e7-4xxx aside from the fact that e7 has 3QPI? does that means you have to have a special MB to run e7 or can you just use a more regular MB with only 1 or 2 QPI to run the cpu with just slower interface? are the e7-2xxx and e7-4xxx in some other ways better than the e5-2 and -4?

Thanks.

so I just learn that there is a lesser known 2011-1 socket for e7 v2 and v3 which appears to make e7 cpu incompatible with 2011 or 2011 v3 boards which run the e3 and e5 cpus...

so I think the seller for thie above item made a mistake because this board will not be able to use the e7 due to difference in 2011 and 2011-1 socket?

2011/2011-3 does NOT run Xeons E3.

Xeons E3 are roughly your standard Core i5/i7s with a name change (Plus ECC UDIMM RAM support), and runs on the same Socket that them. Before the v5 generation, you could actually use them as drop in replacements for the Core line in consumer Motherboards, too. LGA 1155 was for Xeons E3 1200 (Sandy Bridge) and 1200v2 (Ivy Bridge). LGA 1150 was for Xeons E3 1200v3 (Haswell) and 1200v4 (Broadwell). LGA 1151 is for 1200v5 (Skylake) and the current 1200v6 (Kaby Lake). However, since v5 Skylake, Intel restricts them to only work in Motherboards with the C Series Chipsets, so they can't run in the same consumer Motherboard that a Core i7 7700K could (Although you should be able to run the Ci7 7700K in a C236 Server Motherboard).

Xeons E5 include two Sockets, LGA 2011-1 for Xeon E5 1600/2600 (Sandy Bridge-E) and 1600v2/2600v2 (Ivy Bridge-E), and LGA 2011-3 for 1600v3/2600v3 (Haswell-E) and 1600v4/2600v4 (Broadwell-E), the same Sockets that Core i7 HEDT with X79/X99. These two Sockets are not compatible. You should be able to drop a Xeon E5 4600v4 even in a consumer X99 Motherboard and get it working. The Xeons E5 line was recently replaced with the Xeon-W in LGA 2066 (Skylake-X) for the single socket parts and the Xeon Bronze/Silver/Gold lineup of LGA 3647 (Skylake-E). The Xeon-W also required the C Chipsets and don't run in consumer anymore.
There are also two less know Sockets for the Xeons E5 2400/2400v2 (Sandy Bridge-EN, Ivy Bridge-EN) and 2600v3 (Haswell-EN) lines, it was a Socket with Triple Channel instead of Quad that reminds me of Nehalem. The Socket was LGA 1356, and I think the v3 one was 1356-3.

The Xeons E7 v2/v3/v4 (Ivy Bridge-EX, Haswell-EX, Broadwell-EX) uses LGA 2011-2. That Socket is incompatible with Xeons E5. Actually, with Xeons E7 it was possible to get a single Motherboard that could use any of the 3, the magic was that the v3/v4 Xeons E7 bypassed the Motherboard CPU VRM (Is fun considering that Intel justified that Haswell required a new Socket due to the integrated voltage regulator. Probably a total lie considering that they pulled that trick with Xeons E7...). The new replacements are the Xeon Platinums, which shares the LGA 3647 Socket with the Bronze/Silver/Gold.

Let me add your requested information:

e3-1xxx: 1 cpu config
For sockets 1155, 1150 and 1151. Socket 1155 (original, v2) and 1150 (v3, v4) Xeons don't require a special chipset if you don't want to use ECC, while the 1151 (v5, v6) ones always require a Xeon chipset.
e5-1xxx: 1 cpu config
The original ones and the v2 Xeons use LGA 2011 aka LGA2011-0, the v3 and v4 use LGA2011-3. You only need a Xeon chipset if you want to use ECC or registered RAM, otherwise X79/X99 will do.
e5-2xxx: 1 or 2 cpu config
The original ones and the v2 Xeons use LGA 2011 aka LGA2011-0, the v3 and v4 use LGA2011-3. You only need a Xeon chipset if you want to use ECC or registered RAM, otherwise X79/X99 will do.
e5-4xxx: 1 or 2 or 4 cpu config
The original ones and the v2 Xeons use LGA 2011 aka LGA2011-0, the v3 and v4 use LGA2011-3. You only need a Xeon chipset if you want to use ECC or registered RAM, otherwise X79/X99 will do.
e7-2xxx: 1 or 2 cpu config
The E7 Xeons require a LGA2011-1 mainboard.
e7-4xxx: 1 or 2 or 4 cpu config
The E7 Xeons require a LGA2011-1 mainboard.
e7-8xxx: 1 or 2 or 4 or 8 cpu config
The E7 Xeons require a LGA2011-1 mainboard.

The E7 Xeons can have a higher maximum core count then their same-generation E5 counterparts: v2 Xeons are up to 12 cores for the E5 series while up to 15 cores for the E7 series. Xeon v4: 22 cores for E5 vs. 24 cores for E7.

Usually you can use every E5-2xxx and E5-4xxx Xeon on single socket boards, even if the mainboard's CPU compatibility list doesn't mention them.

Don't forget the E5-x4xx Xeons. They are rare low-cost Xeons for LGA 1356 (v2 Xeons) or LGA 1356-3 (v3 Xeons).
There are also other Xeon lines like the E3-15xx ones or the Xeon D processors which are always soldered on the mainboard.

so are you saying that it is possible to have a 2011-1 MB that would run E7 v2, v3, v4? that's interesting. wondering if anyone has one....

getting back to my question, I guess the advertisement for the following is false?

New Intel X79 LGA 2011 Motherboard ATX DDR3 or ECC REG RAM USB 3.0 WiFi SLI OC | eBay

this seller advertise that this board use E5 and E7 v2. So E7 is physically not possible on this x79 MB then?


That's really interesting about E3. why would anyone drop an e3 into their regular 115x board over an i7? the e3 doesn't offer more cores than the i7

Just out of curiosity, has anyone been able to find a 2011-1 MB? I tried google and ebay and couldn't come up with one yet

You better go look for a complete LGA2011-1 server - I don't really think the mainboards are sold separately. Just have a look at Supermicro's line: MP Xeon Motherboards | Motherboards | Products - Super Micro Computer, Inc.

No, I generally wouldn't believe anything a chinese no-name company states. Especially it it's technically impossible.

CPUs like the E3-1230 (original, v2, v3) are basically i7 CPUs (meaning four cores with Hyperthreading) for a cheaper price than the i7. This made them very attractive to well-informed buyers. Probably this is also the reason why Intel added the necessity for a Xeon chipset for E3 v5 Xeons and onwards.

Just look at the link to Supermicro: all E7 boards have the following remark: "Available in SuperServers Only"

Seems like original retail price of i7-2600k and e3-1275 are similar. e3 has a few more instructions supported compared to i7, e3-1270 didn't have onboard video but wasn't really any cheaper, e3-1275 does have onboard video. on ebay right now e3-1270 is around 85-90$, e3-1275 $105-110, i7-2600k $90-100. not much different there if you want to stick to 115x MB.

but if you go with 2011 you get a slightly cheaper and equal e5-1620 for $70.

Few years back, I was able to BIN a lot of 3 E5-1240 v2 at $60 each , just a fancy I7-3770.
I had couple of hours to BIN the 3 x E5-1240 v2 , if it was BIN $60 I7-3770, the listing won't last 2 minutes.

Most home consumers only set their target on I5 and I7 , not E3 v1 , v2.
