There are hundreds available. They were popular, but on the pricy side for good ones. Lots of China boards as you know.
Try "2011 DDR3 motherboard"

he may be talking about a board for the 15 core E7 Xeon he bought. There is no socket R1, just R, so i dont know if hes referring to R or LGA 2011-1, which is R2

LGA 2011-0 (Socket R) - E5 Xeon v1/v2, and 3rd and 4th gen Core i7 (x9xx or x8xx)
LGA 2011-1 (Socket R2) - E7 Xeon v2 and v3
LGA 2011-v3 (Socket R3) - E5 Xeon v3/v4, and 5th and 6th gen Core i7 (x9xx or x8xx)

Yes, I was muttering about the E7- I bought. There are a lot of R sockets out there but very few R1 sockets (except for new ones at $2,000) which is way over my budget :(

Getting ready to pass it down to the next su...k..r err hobbyist who doesn't know any better.

I have put in the listing this "requires" an R1 socket!

tom. R2 socket. or LGA 2011-1.

NOT R1

The cpu specifically annotates on the edge "R1". And furthermore the only MB's I can find that specifically mention that cpu all say "R1" too.

• Socket types: Socket R1 (2011-0 and FC-LGA package)

E7-4890V2 according to the purchase record.

strange, there seems to be a lot of conflicting info about the exact socket design names. but you're right that i do see more references to R1 than R2 (came from wikipedia). i wish i could edit posts on this forum. sigh.

2011-1 (R1) is certainly obscure and near impossible to find a board for. i've never seen a normal ATX board for it. i've seen some of the chinese fake x79's claim to support it, but i dont see how they can support both E5's and E7s when the hold down mechanism has to be physically different since the chips are physically different.

I have examined an E5- and my E7- side by side. They both will fit in a LGA 2011 socket if you ignore the "notches" on the edge of the chips.

Besides having different "notches" the E7- has radically different terrain in the center of the chip (bottom) than the e5- does. The contacts outside of the center "seem" to be a little different in total shape.

Unless the Chinese socket offers two different sets of "notches" on the socket, I don't see how they could do "both" on the same socket.

While I would love to setup this CPU, it doesn't seem to be worth the aggravation of finding an MB that would really run it. There was a "cheap" used one in Germany but it looked like I would need a daughter card(?) to get any video card on it at all.

Another correspondent also reminded me that because these are "older" hardware, they eat a lot more power :(

I wonder.

Does anyone have a treatment for "core envy"?

I have a dual e5-2670 system (16c/32t) running. And I still want a "bigger" box.

Lol, sorry Tom, I haven't found a cure yet, and eventually just gave up looking for one. Moar Korz! Bwhahaha

I suppose that explains that e5-2697 v2 I saw out there the other day :)

Al,
How big a PSU do you have on that 3 X gtx 1080 system?

Just get a single Threadripper 2990WX.
32 cores, 64 threads in a single CPU.

Good point. What kind of power does it draw? I have recently bumped my nose up against the 15 Amp circuit limit in my house that I am not going to be able to get around.

250W, so only a few Watts more than one of your dual socket systems.

That would only be at locked base clock. If you let the system boost automatically and you have the thermal headroom, the testers are seeing 600W out of the MSI MEG Creation motherboard/2990WX combo.

Same for any system- that's just the rating for the CPU & you have to addon the power required for the extra RAM, VRM modules, fans etc and in particular the video card(s).

Edit- would be interesting to see how they came up with that power figure.
The Techreport when running Blender came up with a system power consumption of 360W on a Gigabyte X399 Aorus Xtreme motherboard.



And while that might look bad compared to the i9s, when you look at how much power they use, for the time it takes to process the work, the 2990WX actually comes out in front when you look at the total energy used to complete the task.

I think most of the testers just use the 12V eatx connector or a simple Kill-A-Watt monitor for total system draw. Which is not very indicative of what the cpu alone pulls of course. The reviews usually specify the test setup with respect to what hardware they are running. I would assume 1 gpu of mid-level to high-level class (GTX1080/RX580) and four sticks of memory. (4X16)?? Some of the better reviews use special cable breakout adapters (Gamers Nexus) where all cpu power is monitored through the 24 pin and 8pin cables.

I then think they just let the system do the normal Performance Boost during the Blender tests. Some might venture into the Performance Boost Override which unlocks all the power, voltage and thermal limits to see what the chip can pull under extreme clocking and loading. I just was reading the TweakTown review of the 2990WX/MSI MEG Creation and the system pulled 850W during the Blender tests.

500W more than the Techreport result.
Also running Blender on 2* GTX 1080Tis at the same time?
EDIT- OK, that was using the precision boost overclock- it wasn't a stock result.

Phoronix came up with around 250W running sysbench, over 300W running Xonotic (graphic benchmark).
It's absolute peak was 389W and this was measured from the power outlet, it averaged 186W over all the various benchmarks.

It's good to see how much power a complete system will use under maximum possible load with maximum possible hardware- but when you're doing a CPU review you also want to put forward results that show just the CPU/motherboard power draw, without the video card also working at a high level.
It's interesting that there can be a 500W difference in reported power use for a given benchmark.
Edit- when the systems are configured differently- ie stock setting v overclocked.

I like the Phoronix tests because they mainly focus on server hardware and how it would actually be used. The Phoronix suite of tests is the most complete and capable suite of tests in the marketplace. 80% focused on business and scientific benchmarks and the smattering left on graphics benchmarks. Linux based only until just this year when a beta Windows version surfaced.

Tom, it's an EVGA SuperNOVA 1600 T2, 80+ Titanium, but only pulls about 750 or 800 watts (I'd have to check) out of the wall when crunching, if I remember correctly.
