..but this thread isn't specifically about dual procs. I've been following a thread on overclock.net about the 2670. Sounds like only a baseclock OC to around 106 can be achieved on an X79 board. That being the case a single hex core CPU that can be OC'ed to over 4GHz would be the better part to have - assuming we are mostly talking about gaming potential and one can be found cheaply.
Right now there are places where you can get a Intel S2600CP Motherboard w/ Dual E5-2670 SR0KX , 128GB Ram ECC. That is the superior stepping for $475! Go get them tiger....
Just found a post on reddit talking about the VT-D issues Wendell was talking about.
Looks like if you buy SR0KX you are fine and the issue was fixed, however if you buy SR0H8, then you will have problems. However it seems to only be VT-D so no GPU passthrough.
I actually might pick one of these up while the going is good before they run out. I just had a question about the RAM and motherboard for it. Do I need a socket 2011 motherboard meant for a Xeon chip or would any x79 motherboard work? Would I need ECC memory for it or would standard DDR3 work?
I was looking at using it as a home server for running virtual machines and maybe storage at some point. I'm running a 4770k right now, I may be tempted to use this in my main system for VT-D as the 4770k doesn't support it.
i have an update. what ever you do dont get any intel boards. you cannot expect any support for them. most of them crap out quickly. its also an eol product.
most of these chips were apparently from decommissioned facebook servers. some have clean pulls others are damaged and sold as used. friend of mine lost 70 bucks recently because of this.
there are supermicro boards too. there have been reports of dimm slots being blown after a few months. amazon and newegg reviews are your friends.
i don't suggest getting 2 of them on the same board too. there aren't many good boards and most of them are used and ridiculously expensive.
get a newer gen soln. it'll work for much longer and also be alot more reliable. most noteworthy thing about the 602 chipset is that most boards don't have native sata 3 or ecc support. intel states that the memory check happens on cpu, however most boards claim that ecc is not supported. and supermicro has falsely advertised the speeds on the pcie. the 16x pcie 3.0 is a 8x slot
i can attest that the sr0kx does virt passthrough. the sroh8s however do not. my first chip was the sr0h8. it turned out to be an engineering sample too.
Hate to drag this back up, but I was thinking about getting a new home server and heard Wendell mention several times how amazing the E5-2670 CPUs were.
I was thinking about getting a couple Hyper 212s. Would they work on Socket 2011? Would they fit in a 4u case?
The motherboard bothers me a bit. It's "manufacturer refurbished". Is there a better motherboard option in the $200 to $250 price range? Dell and HP boards bother me too, mainly because I am unsure of the physical size and mounting.
@noenken That is one badass computer. I wish I could go with that motherboard, but it's a bit expensive for my budget. Looks really good, though. Mine would be hidden away in a Rosewill 4u case.
@gigabit I would jump on that combo, but I'm trying to keep it between $400 and $500. My parts list comes out to about $450. The extra 64GB of RAM for about $100 is a pretty good deal, but I really don't think I'll need 128GB RAM. I wonder how often it's in stock, though?
The main reason for it was the IPMI port. Never ever having to worry about monitor/mouse/keyboard anymore, even for BIOS/UEFI stuff, that is easily worth the extra money.
I remember that video. I am almost positive that the Intel S2600CP has IPMI. At least Intel Ark says it does. I can't wait to learn and use IPMI too.
I just checked around on the site @gigabit linked to and found a combo that includes only the motherboard and two processors. The cost there is significantly less than buying them individually off ebay.
Anyone have experience with the Intel S2600CP? It has a PCI-e x16 slot, but I think it is x8 electrical. Would this be a bottleneck for a video card? Here's the Ark page for the motherboard in the combo: http://ark.intel.com/products/56333
If you go with the Natex combo with 64gb of ram use the Coupon code: S2600CPPACK for 5% off. Its something. Natex is great thats where i got my combo. Works great...
And yes all slots are 8x electrical and you wont notice a difference in frame rates from a gpu.
Maybe I'll make a new thread in a week or two documenting the transformation of my home server. I need to get a new camera to take pictures, though.
The really cool thing about that combo (and the 128GB for that matter) is that it is 64GB of 1600MHz DDR3 ECC Registered. All the 1600MHz RAM on ebay is freakishly expensive. I was going to settle for 1333MHz.
So I actually own a similar cpu (e5-2667v2), I run it on a dual socket board (paid ~$4,500 for the two cpus alone back in 2013). It's an excellent cpu and $75 is really a steal for this one (basically free).
I've been able to get mine to reach around 350 gflops and 4ghz - def would recommend someone to get these.
