Report on $70-$80 Gtx 1060 3GB cards on eBay. GPU-Z reports them as "fake" and they are running 172 shaders. Maybe a half hour per task under windows.

I am wondering if the non-Intel MB will support running more at the "turbo boost" end of the e5-2670 (base: 2.6Ghz, Turbo: 3.3Ghz).

The Intel MB s2600? had a lot of parameters but nothing I could easily put my finger on as increasing the Turbo.

Is there another MB out there that supports reliable all the time turbo boost? I am not really talking about "overclocking" just running at the top end of the production system.

One thing you might find is that all PCIe slots may not be active without 2 CPUs installed.

I have now had a chance to read some reviews. The results run all the way from not-reliable after a few months up to running fine after 18 months. Apparently this is an early MB from them. In 2016 Win10 wasn't running on it and neither was Server 2016. I don't remember but I may have Server 2016 installed on the existing HD's on raid 1. Oh well, I have lots of Win7 product codes :) And who knows, maybe a bios update has cleared some of the issues.

The current plan is to install both cpus from the previous dead MB, all the ram that will fit (looks to be half of the previous MB) and migrate my 2 gtx 1060 3GB that were running like greyhounds on my other Xeon box. I have a brand spanking new 850 watt Antec to cheer this new MB on.

I just read through the parts of the AnandTech review that hasn't quite finished yet. But they did write the conclusion already. The best choice overall is not the 32C/64T 2990WX part, it is the new version of the 1950X, the 2950X 16C/32T part based on the new Ryzen+ 12nm process. $899. $100 cheaper than the first generation.

In applications that play to it's strengths, nothing else can come close to it. however in applications involving lots of memory bandwidth, it lags, significantly.




The 7-Zip Compression & decompression tests are very telling.



Techspot have a good explanation of what is going on.

The problem is memory bandwidth, as there simply isn’t going to be enough of it. We still only have quad-channel memory access, so memory bandwidth remains the same, but now we have twice as many cores to feed.
...
The TR 2950X features the same layout as the 1950X and that means it comprises two active Zeppelin dies, each packing 8 cores, two memory channels and 32 PCIe gen 3 lanes. When using DDR4-3200 memory the Infinity Fabric throughput between these dies is roughly 50 GBps.
…

The 2990WX on the other hand is a very different beast. It consists of not two Zeppelin dies but rather four, enabling up to 32 cores. However on the X399 platform AMD has imposed some limitations to avoid cannibalizing their single socket EPYC server CPUs.

The biggest of these limitations being that there are still just four memory controllers. Although there are two more Zeppelin dies, the additional two dies are compute dies, in AMD’s words. This means they have no local PCIe or DRAM access, for that they must travel via the Infinity Fabric to the IO dies. As there are twice as many dies, the Infinity Fabric bandwidth is also halved, so now the throughput between dies is just 25GBps, assuming you’re using DDR4-3200 memory.

Techspot review.

This question is about how to setup the bios of a high end 16c/32t motherboard.

The basics are clear via a discussion with Wiggo some time ago.

1) Turn off the motherboard wait states. aka: Intel Speedstep.
2) Turn on Intel's "Turbo Boost."

Many motherboards don't really let you tinker with the "standard" overclocking features.

The Intel motherboard I had previously didn't clearly state (as I think I remember) where to turn off the "wait states" and where to turn on the "Turbo boost."

Discussion: On your high core count MB what tuning did you try or not try?

Thank you,

Darn.

We were installing the new PSU on the 16c/32t box when we came up "short" (the cables were too short) :(

So that is put off while I RMA the PSU and find one with longer cables. Darn. I was hoping to watch 32 threads and two gtx 1060 3GB video cards start smoking on Saturday evening.

Companies make extensions. 1st one on Amazon as an example.
https://www.amazon.com/Phanteks-Extension-Cable-Length-PH-CB-CMBO_WT/dp/B01G7VOYYS/ref=sr_1_4?ie=UTF8&qid=1534686257&sr=8-4&keywords=power+supply+extension+cable+kit&dpID=41o97g-pi2L&preST=_SX300_QL70_&dpSrc=srch

The extension kit you listed has only one 8-pin CPU cable extension; he needs 2 of them for his board (2 CPUs).
He could buy two sets, of course.

Or try eBay for individual CPU cable extensions.

They are cheap.

Kit autofilled my search so it came up with kits. Of course single cables can be purchased new. Its probably cheaper to buy the extensions than to ship a PSU back.

Finally got one of my E5-2670 boxes up and running. I was trying to setup a dual boot and for some reason Win7 got all cranky on me. So I threw up my hands and setup an "all" Linux box using the latest Lubuntu distro.

Since this one doesn't really have much of a GPU it looks like a "headless" server on my computer page on seti.

It has just barely downloaded some tasks so its going to be a while. I am saving my pennies for at least a used Gtx 750Ti. :)

The dual cpu e5-2670 is waiting on some extender cables so that I can actually power up the motherboard :) Maybe later this week? It shouldn't have any issues (fingers crossed) with getting Lubuntu on it. And it is starting out with my entire supply(2) of gtx 1060 3GB cards.

I know it will have a very decent RAC but who knows how long it will take to get up there.

I poked around in the Bios for this "Intel X79" MB and finally did find the "speed step" setting and got it turned off. It also mentions a profile where you can set "save power", "balanced" and "performance". I switched that to performance. It also said the OS "power plan" would over ride that. Now I am wondering if Linux has a "power plan" utility and what it is called?

I am still wondering if there is a way to get an E5-2670 to run at "extended turbo-boost" all the time? According to Intel "Extended Turbo Boost" runs all the cores, all the time, in turbo-boost (I think).

If you're using an AVX app then CPUs will typically boost/Auto OC to a lower clock as AVX works the CPU harder.

On my two dual Xeon crunchers, the E5-2670s (v1) always ran at 3GHz when doing SETI, and the current E5-2680v2s all run at 3.1GHz (all 300MHz faster than nominal speed), which I believe is the extended turbo speed for all cores, so you won't have a problem. It is the default.

I am experimenting with AVX on my i7-3770 box. And the tasks I have found, so far, are all claiming to be running SSE not AVX :(

I am running the CUDA90 aka: secret sauce on my single cpu e5-2670 v1. It defaults to SEE 4.1 and SEE 3x?

I remember that the AVX cpu task under the Lunitics beta7 distro was very much faster than stock. What I am not sure is how much faster than SEE it was.

Use Task Manager or Process Explorer to see exactly what executable is actually running.

You keep confusing GPU & CPU instruction sets.
CUDA is for Nvidia GPUs. SSE & SSSE are CPU instructions sets. I'm not aware of any SEE instruction set.

I remember that the AVX cpu task under the Lunitics beta7 distro was very much faster than stock. What I am not sure is how much faster than SEE it was.

I'm not aware of any Beta7 installer. Nor am I aware of anything known as SEE.

With the applications in the Beta6 installer the AVX application was about 30-40% faster than the SSE application (depending on the WU being processed).


It may seem like nit-picking, but you need to use the correct terms & acronyms, otherwise people end up working at cross purposes and can't make sense of what the other person is talking about. Things here can be confusing at the best of times, without making them even more so.

I apologize.

The "SEE" was a straight typo. :( The Lunatics BetaX installer was me displaying really bad memory. I thought I remembered Beta7.
