    The Consolidated Xeon E5-2670 Thread

    Now in a handy FAQ format. If you ask a question in the thread which is answered here, I will simply reply READ OP!! in extremely large, red and embarrassing for all of us text :D

    Without further ado:

    1. What is this fabled Xeon E5-2670?

    It is the Sandy Bridge-EP Xeon E5-2670, an extremely good value-for-money LGA2011 (original, not LGA2011-3) chip.

    It's 2.6 GHz, 3.3 GHz Turbo, 8 Cores, 16 Threads, 20 MB cache.

    We are talking about the SR0KX model of the E5-2670 which is the C2 variant with better compatibility and VT-d support.
    The SR0H8 is the C1 variant, and is not really covered unless specifically stated.


    2. Where can I get one?

    Cheapest on eBay is currently (29/4/16):

    Here from hwtrade-e (based in Hong Kong), at $64.99 US + $10 US shipping ($98.33 AU delivered, 29/4/16)

    You can also get them from Tao Bao, Natex or a variety of other places. If you want to investigate these options, read the thread. This post is deisgned for the "average joe" who just wants 1, 2 or 4 without using a US-based shipping forwarder etc :lol:

    3. Will they work in any LGA2011 X79/C602 board?

    So far, yes. We are yet to find any users who have had compatibility issues with this CPU. They have worked in literally every board we've tried them in :)

    4. Okay, cool. So where can I get a dirt cheap LGA2011 board to run it in?

    You can't. No ifs, no buts. This is now all over the internet so every man and his dog is on the lookout for 2011 boards. Here are your options:

    a) lurk OCAU FS and hope that someone sells one with a stupidly low instant, and that you refresh faster than I do :Pirate:

    b) follow this thread - single-socket workstation boards are reasonably readily available at ~$250 US plus post, dual-socket server boards are reasonably readily available at ~$350 US plus post. But sellers tend to run out quite quickly so there's no point trying to keep this up to date here.

    b2) some other OCAU-ers bought multiple boards in case of DOA boards etc, so again follow this thread and see if anyone who bought multiples would like to sell.

    b3) seach eBay for C602 instead of X79. Look for workstations which used LGA2011. Every man and his dog might be after boards, but every man and his dog don't know that these run in a HP Z420 workstation (for example, there are Lenovo and Dell options too), so they're not searching for those :D

    c) you already own an X79 board with a low-end quad-core i7 in it.

    d) use one of the opencompute server modules that these CPUs originally came out of. This is an enterprise-end setup, with one PCI-E slot, a non-standard form factor, non-standard PSU, no power button, no video output and about 3 BIOS options.

    5. Can I OC the shit out of it, like the bargain X5650/X5670 LGA1366 Xeons?

    No, you can't, the multiplier is locked. There is room for a small tweak in BCLK if you know what you're doing and the implications of doing this.

    6. Is it worth it to build a system based on this chip because it is super cheap?

    Depending on your application. For a server / workstation where a bunch or threads and tons of RAM are real advantages for you, then yes. It's worth spending extra $ on buying a motherboard to run these chips.

    For gaming / general use, unless you can score a super-cheap LGA011 board, the relatively low clock speed and lack of any real OC means you're probably better off getting a more modern combo with a cheaper/newer board and a more expensive CPU.

    7. Rubbish! I want proof!

    Read this entire article. PLEASE DO NOT ASK A QUESTION IN THE THREAD UNTIL YOU HAVE READ THIS ARTICLE:

    http://www.techspot.com/review/1155-affordable-dual-xeon-pc/

    and particularly this page:

    http://www.techspot.com/review/1155-affordable-dual-xeon-pc/page7.html

    8a. What is the difference between the X97 chipset and the C602 chipset?
    8b. Can these CPUs run Registered ECC DDR3?


    X79 = desktop chipset
    C602 = server / workstation chipset

    Basically, the X79 chipset with an E5-2670 can run:
    - standard DDR3; I got mine booting into Windows with 4x 2gb @ 2133 in my sig rig.
    - non-registered ECC (we think)
    - registered ECC in the 1Rx8 configuration (again minimal testing has been done

    The X79 chipset cannot run Registered ECC 2Rx4 chips which are insanely cheap at the moment (except for a couple of notable AsRock boards, see table below)

    The C602 chipset with an E5-2670 can run everything we've thrown at it so far.

    9. Where did they come from? Won't there be a flood of cheap boards too?

    They came from racks of decommissioned opencompute servers, probably from Facebook.
    More info here: https://forums.servethehome.com/ind...2-x-dual-2011-nodes-199-quanta-openrack.6856/
    If you want to go into this in side of things in more detail, these nodes are available pretty cheap on eBay, but it's covered extensively in the above thread, we don't need to go into that much detail here.

    There is unlikely to be a flood of boards, as this is a case of supply way outstripping demand. There are probably not enough single and dual socket ATX/EATX/SSI/EEB boards in existence to use a whole datacentre load of these CPUs. The only way to "soak" them up would be to put them all back into the opencompute servers they came out of.

    My 2c (not solid fact): There were even fewer X79 desktop boards sold than X58 boards, due to the fact that X79 wasn't a massive improvement over Sandy Bridge, not compared to X58 over 775/1156 etc. For example, the average OCAU-er could get away with a Sandy Bridge rig for their daily machine, and go stupid with 5ghz i5-2500ks if they felt so inclined. They did not need X79. Whereas previously, an X58 board and i7-920 was a pretty staple diet for guys upgrading their Q6600 rigs.

    So when the cheap 1366 Xeons showed up, it was obvious to replace their low-end 920's etc with dirt cheap, mad OC-able X5650s. And there are still X58 setups that will hold their own in current-gen applications, for the average user.

    But most people that went for X79 had the money to buy a reasonable, unlocked 6-core CPU straight off the bat, so there's little point buying one of these. Unless they're stuck with the cheapest entry-level i7, and even then, quad core with higher raw clocks is probably going to be more useful for gaming and daily use right now than 8-cores stuck at 2.6/3.3


    10. I'd like some real-world benches and price/performance comparisons. What have you got for me?

    Watch this space. In the meantime, if anyone has done benchmarks, add them to a post and let me know and I'll pop them in this section :)

    Once my GTX780 arrives, I'll try to run numbers using that same GPU and SSD in all of the following:

    i7-4770 Haswell 1150
    i7-2600 Sandy Bridge 1155
    X5650 Westmere-EP 1366 / i7-950 Nehalem 1366 (can't seem to find the X5650 :confused:)
    E5472 771/775

    I will do some comparisons with CPUs @ the same base clocks, some @ stock clocks, and some with a realistic OC.

    Also planning to check out the performance difference with 4x 2gb 2133 @ everything from 1066 to 2133.

    Then rinse and repeat for multiple channels @ 1333:
    1x 8gb 1333 vs 2x 4gb 1333 vs 3x 2gb 1333 vs 4x 2gb 1333

    Not to thread crap too much but could it also be a workstation/server board deals lookout thread? Probably many of us looking for some reasonably priced dual socket 8/16 DIMM boards :thumbup:

    It should work in a Gigabyte X79-UP5, which has a C606 chipset.

    Sure! Title updated to reflect, have PM'd Kelvin for his input with dual socket compatibility / deals. (I know he had one board which ran two of them but the fans ran flat stick and there were some other issues iirc)

    Yeah it's on the list since F4. I will add it as "Manufacturer Supported" not "OCAU Proven" :D

    What is the significance of the C606 chipset?

    Nah unless I'm looking at a different list, the Asus site for the X79 Deluxe says the Intel Xeon E5-2670 v2 (2.5G,115W,L3:25M,10C,HT) is compatible, but that's the Ivy-EP version (10 cores 25M cache) not the Sandy-EP version :thumbup:

    This is the server chipset. There is a C606 and a C602. So most Xeons should be supported on these boards.

    I'll put my 5cents in then..

    Z9PE-D8 WS - from the forums SSI EEB size
    Dual E5-2670
    Non ECC, Standard DDR3-1600 8x8gig sticks
    Paid $500 for the pair of CPUs a couple of months back..:sick:
    The fan controller settings are very very spatan on the board.. compared to the other asus boards I've used..

    ...........................
    Ordered
    Asus Z9PA-D8 Around $515 delivered...
    http://www.newegg.com/global/au/Product/Product.aspx?Item=N82E16813131886

    Ordered Matching soundcard around $33 delivered to the US
    http://www.amazon.com/Asus-892-Serv...p_p_img_2?ie=UTF8&refRID=04TRJ9D1VACQ4SEQPCYW
    (Now near impossible to find)

    Ordered SROKX -C2 E5-2670
    http://www.ebay.com.au/itm/SR0KX-E5...337392?hash=item2361c7c4f0:g:rvQAAOSwLnlWnVog

    Ordered 8x8gig ECC Registered DDR3-1333 memory for around $200
    http://www.ebay.com.au/itm/8x8gb-64...DL160-G6-G7-/141888187475?hash=item210931ec53


    Note the dual Socket 2011 boards are disappearing fast from Newegg, a couple of months ago, there was a wide range and choice of boards.. most are now EOL and getting snapped up by US
    https://forums.servethehome.com/index.php?threads/intel-xeon-e5-2670-deal-and-price-tracking.7133/

    Issues,
    From I can get gather.. the bad reviews of the asus dual boards is partly because... non ECC ram will only work in single configuration, and dual Sandybridge EP, Dual ivybridge-EP apparently required ECC ram..
    This isn't documented anywhere... but mentioned in a couple of threads
    The cpu socket spacing on the z9da will be very very tight.. Finding hsf may be difficult

    Ty :D

    If only those prices were available for 16GB sticks :(

    I'm tempted by the Tyan S7050's that keep popping up on eBay, I haven't used a Tyan board before but haven't heard bad things before.

    I've also noticed some Dell boards, mostly T5600/5610/7600 workstation boards, some are 8 DIMM and some are 16 DIMM, might be worth a shot for anyone who feels like risking it? The 16 DIMM T7600 is ~$300 delivered.

    Overall plan for me is to upgrade the L5639 box in my sig to a dual E5 system with 256GB RAM, will be making the move to VM's :D

    I can confirm these chips work on a Rampage 4 with 4901 Bios.

    Could only overclock a tiny amount using base clock. Was able to run 106.

    No strap or multiplier overclocking available. Also note that the full turbo multiplier is unavailable on all cores etc as well.

    I've got one of these coming plus a Gigabyte X79-UD5 which has official support. 16 threads for under 150. Can't go wrong.

    That's great..
    I was afraid I was going to have to ditch the asus boards

    I wonder why they aren't officially supported???? When they had official support previously

    Decided to use my 2670. Works fine on X79-deluxe. In fact running 8x4G ecc registered. However can't really tell any improvement over the old x5650@4.15G, possibly even a downgrade due to much lower freq.

    I'm half considering grabbing one of these for some gaming as the current system I use is getting very long in the tooth, I already have a mobo ready to drop it in to so just need to grab the processor. Would this run football manager/fallout 4/battlefield 4 decently at 1080p coupled with a 750ti or a 950? Possibly the wrong place to ask so don't chew me out :lol:

    Ah okay, thanks for the info.

    Thanks Kelvin, will add to the list.

    Which Rampage 4? Extreme? Formula? Gene?

    Thanks for the info :thumbup:

    Which version of the BIOS are you running on the X79-Deluxe? :thumbup:

    Nah all good, ask away. At this price, a few people will be considering these CPUs for gaming I'd say.

    Mine should be arriving within the next day or two, so I can do some benchmarks for you in some games... although I think my only working GPUs are a 780Ti Classy and a 6970... neither of which is really comparable to a 750Ti :lol:

    Wait sec.. You are using registered memory on your x79 board with a xeon...

    Does the registered memory worked with a standard i7 .. Or just the xeon

    Hmm at that price it's worth just grabbing the CPU and waiting for a cheap board to come up...
