Message 2013553 - Posted: 27 Sep 2019, 23:31:02 UTC

I have counted about 9 machines running Intel E5-26xx v1/v2 cpus in the top 250 or so Seti@Home participants.

The reason I am ruling out E5-26xx v3/v4 cpu/motherboards is because they are not socket compatible with the v1/v2 cpu/motherboards.

I would be very interested in seeing what motherboards everyone else is running. I am on my 2nd MB in two years. And it just decided that it's 2nd cpu socket is no longer recognized. So I am running a 1 cpu E5-2690v2.

Don't get me wrong. The gpus are humping along as good as they ever have. But I really want to get back up to 2 cpus.

I have burned out a stock Intel MB in about 9 months. And an ASRock MB after being pushed pretty hard, it didn't survive completely its last transplant.

I know that one of Ian's MB's is a SuperMicro x9drx+-f server MB is running 24/7.

So what else do you have? Some of you are clearly running single cpu E5-26xx setups but I still want to know.

By Christmas I hope to have made up my mind about which MB new, used, refurbished, other I will get next.

Yes I am looking at: supermicro x9dr7-ln4f and supermicro x9dri-ln4f+

I am pretty committed to wanting 6 or more gpu slots because I want to be able to drive at least 6 gpus. And while I am price sensitive I may break down and buy a brand new MB just so it won't quit so soon.

Comments?

I have, or have used the following boards with good results:

Supermicro X9DRX+-F (Proprietary FF) - running my 10-GPU Seti machine w/ 2x E5-2680v2

Supermicro X9DRi-LN4F+ (Proprietary FF, but will fit EATX mostly if you have a large case) (Also be aware that only rev 1.20 boards are compatible with v2 CPUs, v1.1 or 1.0 will only work with V1 CPUs) - Running my NAS/VM server w/ 2x E5-2680v2

Supermicro X9DRi-F (EATX) - Running my 3-GPU Seti machine w/ 2x E5-2630Lv2

Supermicro X9DAi (EATX) - running my secondary Plex server for GPU transcoding to remote clients w/ 2x E5-2630Lv2

Supermicro X9DAE (EATX) - running the NAS/VM server at my parents house w/ 2x E5-2630Lv2

AsRock Rack EP2C602-4L/D16 (SSI EEB) - running a Plex/NAS/VM server for a friend w/ 2x E5-2667v2

Supermicro X9DRi-F (EATX) - Running my 3-GPU Seti machine w/ 2x E5-2630Lv2

Both of these are "narrow" cpu cooler boards. I can get the first for ~$600 (new?) and the 2nd for ~$215 (used).

One has 11 gpu slots and the other has 7 gpu slots.

Assume you are price sensitive. Assume you will run a mixed Set@Home and World Community Grid on the cpu side (maybe 50/50).

Which would you pick? Would you search for a new X9DRi-F?

The other interesting thing I ran across was a review of a "Workstation" version of the E5-26xx v1/v2 cpu. Apparently it has a much higher turbo speed even if it is not clear how fast the "all core" turbo would be.

I think this is an example:
Intel(R) Xeon(R) CPU E5-2687W 0 @ 3.10GHz [Family 6 Model 45 Stepping 7]


And the cpu list shows a total of 25 split between v1 and v2's.

There is no difference between the 2687Wv2 and the 2667v2 in real life. They have the same exact turbo bin speeds at every core utilization. The only difference is the baseclock, which you will never be running at unless you’re thermal throttling the chip. There’s no real reason to get the 2687Wv2

It’s really up to you to decide. I think the X is much better for multi-GPU, but it’s up to you to decide if the cost is worth it. The DRi-F is probably better for you, and will fit in any EATX case.

Puget Systems always has good information about the merits of each E5 processor. Lots of charts and comparisons.

The cpu you are considering is specifically mentioned in this article as the better deal. And to answer your question that cpu has an all-core turbo speed of 3.2Ghz. But if you are considering only V1/V2 parts this one will not work as it is a V3 model.

On the EVGA X79 Dark, the 2687w v2 is supported in the Bios while the 2667 v2 is not, though the 2667 v1 is supported as is the 1660 v2 cpu, I'm currently running a 1650 v2 cpu which is unsupported as is the 1680 v2.

2687w v2 is 150w
2667 v2 is 130w

Asus supports more E5 26xx series cpus than does Evga, I have both.

In a few days I'll have to reboot the PC, after 8 days it's this or the motherboard will do this by itself and the motherboard is a refurb from Evga.

eBay seems to think there is an animal called a e5-1680 (8c/16t) if your cpu envy kicks in :)

I just stumbled across the mention of an e5-2658 v2 (10c/20t) 2.4Ghz with a TDP of 95 watts compared to a e5-2690 v2 (10c/20t) 3Ghz with a TDP 0f 130 watts. That in turn got me to remembering something that Ian had mentioned about a lower power cpu so found he is using a couple of e5-2630L (6c/12t) with TDP of 60 watts.

I can see if the cpus are mostly pushing gpus and crunching cpu tasks on the side at a lower TDP it would likely reduce your electricity costs?

It turns out used e5-2630L's are not too pricey either. Maybe I should "buy down" :)

I got the 2630Lv2 chips for exactly those reasons. They are very cheap, low power use, and “good enough” clock speed to run GPUs. I don’t run any CPU WUs anymore.

I also use these in applications where CPU clock speed isn’t critical. Like a midrange home NAS system, or a system doing GPU video transcoding for a media server.

With a supporting motherboard and 2x E5-2630Lv2 you get:
-12 cores / 24 threads
-2.4GHz base clock with all-core turbo of 2.6GHz and single core turbo of 2.8GHz
-80 PCIe 3.0 lanes
-120W TDP (for both, 60w each)
-$50 price for both including shipping from eBay

It’s really a great little chip if your application won’t be bottlenecked by the low clock speeds

This is a great page to compare the real clock speeds and specs of the various E5 Xeons.

6? Sure, if you have 6 single slot gpu cards, most are dual slot these days, with the right case and psu you might be able to use 4 dual slot gpu cards.

I'm doing only 3 gpu cards cause of My choice of psu supports 30Amps per 12v rail and two 12v rails are shared with sata/pci-e and so three 12v rails for gpus can be used and the 4th for sata and molex and the 6pin or 4pin pci-e motherboard power connector, mix gpus with sata and molex and pci-e motherboard connector and ocp could be triggered as Enermax says. 3 gpu cards per case also allows better air floor for blower type cards.

Yes an E5-1680 v2 3.0GHz cpu does exist, but is about as supported as My 1650 v2 is on My Evga X79 Dark motherboard.

I checked the Bios support for the Asus RIVBE and the RIVE motherboards and both support the E5-1680 v2 cpu, among others.

Another participant replied privately reporting:

My two machines use an ASUS Z9PE-D16 and an Asrock EP2C602 dual Xeon MBs. The Asrock has been running 24/7 since June 2016, the ASUS 24/7 since Feb 2017. Very few problems (a couple of (bought used) water coolers died at random times when I stopped one of them for maintenance, which I do rarely) was the main problem. Temps are good, but I keep an eye on them just in case...

Just feed them lots of electrons, and they are happy - ~1100KWH/month.

Tom M asked me to post with my config. This is my all-purpose Linux system at work:

HP Z820 (a beast @ 55lbs)
1125 watt PS
HP v1 motherboard (p/n 708464-001)
Intel C602 Chipset
2x E5-2620 @ 2.00GHz
Piles of ram
1 GTX 1070Ti
1 low-end ATI FireGL card, maybe a 3000.

https://setiathome.berkeley.edu/show_host_detail.php?hostid=8668207

Overall impressions, this system runs quiet, cool, and very reliable. It's running 24x7, been that way for months. It was in use as a video editing system for 5-6 years before I snagged it.

Ebay has a fair number listed, expect to pa ybetween 500 and 1000 USD + shipping for a dual-cpu config.

The power supply should support 3 dual-width cards, but I haven't had the slack time to give it a go.

The V1 version of the motherboard doesn't support the later E5 Xeon's. That would let me use some of the later lower-power cpus. Only noodling, haven't looked at the tradeoffs seriously.

What else would you like to know?
