Using E5-4650 in single processor motherboard?

I've looked for hours.

Single E5-4650 in a single or dual processor motherboard sporting C600 chipset series? Is this possible? I can't find ANY motherboard that lists E5-4600 as a compatible processor. The only board I found was a X79 chipset, but I don't want to be limited to 64GB of RAM and I want to use ECC.

I can buy the 4650 for cheaper than I can get the 2680.

Essentially, I'm looking if one of these boards (Newegg search URL) would work, or any other you may know of. I can't find any info on any of SuperMicro, Intel, ASUS, Tyan, or Gigabyte's site saying E5-4600 is supported with a single or dual proc board.

Obviously, I do not want to use a quad board to run 1 processor.

So is anyone using a chip in such a configuration?
 
Should work just fine in any C6xx board. They're just not advertised to work because no one normally buys CPUs intended for 4-way setups for a single socket board. Quad socket boards actually use the same chipset for the most part (C602 is pretty common). Plenty of Supermicro board that will fit the bill and let you use up to 256gb of RAM.

Oh, and posted the wrong one, other then that, I bet there are other that have the necessary microcode but don't advertise it. Asus usually have good coverage.
But a mail to all mfg with a question can be better answer.

Thanks, but the Extreme11 also is limited to 64GB RAM ... although I didn't realize both of those boards do ECC.

I like the email to mfg idea. I'll see what they say.

My heart agrees with you, but my brain is more fickle.

If you look at the previous ASRock links, they specifically say compatible with:
E5-4650(C1)
E5-4620(C1)

This says nothing about the other E5-46xx chips (all of which were released ~mid-2012):
E5-4603
E5-4607
E5-4610
E5-4617
E5-4620
E5-4640
E5-4650L

Furthermore, the E5-4650 is composed of the following steppings:
C0 (QB83)
C1 (QBED)
C2 (QC6M, SR0QR)

And for the record, the E5-4620 has:
C1 (QBFK)
C2 (SR0L4)

This is curious to me since the various differences in the 46xx family appear to be clock/voltage, memory bandwidth & speed, and certain enabled features like HT. It really doesn't make a lot of sense other then perhaps they only had those two chips on hand to test and their lawyers wouldn't let them post the others(?)

I'm afraid I am not very well versed on the direct differences between the steppings and how that can directly affect how it is managed within BIOS. I guess I always presumed it was an alteration of algorithms within the firmware of the CPU that had no effect on outside interaction with the processor, but I am not a BIOS programmer so I don't know.

I tried looking up BIOS firmware as well from Supermicro and the other manufs, but they don't have any mention of supporting the E5-46xx series.

I was hoping to hear from someone who has this running, but I appreciate the vote of support.
 
Could always give Supermicro a call during the week and get confirmation from one of their engineers. Those steppings seem odd. The 4 character ones are engineering samples and 5 character ones production. I'm not sure why ASRock would list only ES CPUs (or even mention them in the first place).
 
It might be worthwhile posting in the Distributed comuting sub forum - Even on [H] running an E5 4xxx CPU is top end, they are about the only bunch on here that i know of that are even using those cpu's
 
Supermicro X9DRi-F works with E5-4650's (C0, C1, retail, not sure, but no reason to think would not support C2).
 
Hi
I am in the same situation. I have a Xeon E5-4650 and am looking for a single CPU ATX X79 motherboard that is compatible.
I have has so much conflicting information that I am now totally confused. The following sites actually list lots of boards that are OK:
Http;//www.game-debate.com/hardware/index.php?pid=1186&moboList=Xeon%20E5-4650
and
http://www.pcspecs.com/cpu/Intel/Xeon_E5_Series/Xeon_E54650/1186/Compatible_Motherboards
One would think that at least a few LGA2011 SocketR boards would OK. However, Asus and Gigabyte have both stated that their X79 boards would not be suitable. Whereas ASRock have now confirmed twice that theirs are.
I'm stuck with a chip I can't use! Has anyone had any luck sorting this out.

Not to my knowledge, I have heard of running a 4650 as a single chip in a 4p board but not a 1 or 2p
 
Most ROG Asus boards should take that processor, especially the Rampage IV Extreme. My Rampage IV supports Xeons, and works with both the E5-1660 and the E5-2687W. Only problem is that you're going to running at a crappy clock speed with that processor in a single board vs something like the E5-2687W. But it should work...;)
