Dunno how effective it would be for Seti crunching, since most apps require sufficient CPU support.
It has been shown and discussed many times that multiple rigs supporting a couple of GPUs will crunch better than hanging many GPUs from one mobo. Dunno if that has really changed much over the years.

I agree, I don't like the idea of having to use a Kabylake CPU, not enough cores and not enough PCIe lanes..

Same here as well, because personally I did not like this one too much.

The question becomes whether or not a hardware solution is better than a software solution.

So perhaps a question for Zalster here of whether it should perhaps be Core i9 rather than Core i8, or perhaps vice versa?

Recently purchasing a second computer which is still unopened in the box, one or two main processors, together with perhaps two or more graphics cards,
could still be the better solution, because that of virtualization, together with everything from multitasking through setting of affinity, as well as also a given task priority
by means of both threads available and also memory, should be a better solution.

https://en.wikipedia.org/wiki/Virtualization

Mentioning it, because it is a more complex feature and because of that I got a note of it at PrimeGrid by one of the moderators there.

Just connecting because it looks more like ISA rather than at least PCI, a graphics card today is neither AGP or VESA either.

Currently experiencing a surfing problem because of a failed installation, at least keying in PCI Express using a Toolbar or search engine should give some answers back.

https://en.wikipedia.org/wiki/PCI_Express

https://www.nvidia.com/page/pci_express.html

These two suggestions when using Yahoo! rather than Google Chrome.

Also keying in pci express video card, or pci express 2.0 x16 should also return some results back.

Next apparently both PCI Express 2.0 and 3.0 are currently available and next possibly pci express 3.0 x16 here.

My bad perhaps here, because I should rather be checking, but for now I think it should be PCI Express 3.0 here, as mentioned above.

Finally do not forget the graphics cards themselves either.

Of course after I said this I saw the new i9

Intel Core i9-7900X X-Series 3.3 GHz Ten-Core LGA 2066 Processor

Hmm.. I still don't like only 2 stick of RAM....

The B250 is the lowest end chipset with the fewest features, but it does support 12 PCIe 3.0 lanes. The CPU also has its 16 PCIe lanes.
It is plenty for a miner, but since you can only put an i7 with 4c/8t in it wouldn't do much good for projects that need more CPU support.

If you wanted to go nuts with GPUs you would probably be better off with a 20 slot PCIe backplane setup.

My question would be, will it recognize 10+ cards? I have that 10 slot PCI-e 8x dual Xeon Supermicro board with more than enough lanes, that due to memory limitations can only recognize I believe 6 cards, so how would this one be different? Nothing I could do to make it work, and Supermicro said it wouldn't work either. I documented it in my build thread, something about memory space or whatnot if I remember correctly? Is that a Windows limitation, a hardware limitation that can be overcome with proper design, or something else? I'd love to try to get all 10 cards working, but I believe it's a lost cause.

It turns out you need to run Linux in order to make it work. Only 8 Nvidia and 8 AMD cards currently.

AMD is said to be working on a new driver that will allow full 19 PCIe usage.

I wonder if one of the new i9 10 cores would work in it??? Ideal would be an Threadripper Mobo with 19 PCIe slots...But then the question becomes, how in the HECK do you power all those GPUs and the board????

The first issue you would have with putting an i9 on that board would be shoving a LGA2066 CPU into a LGA1151 socket.

A couple of weeks ago, AMD had released a beta driver geared towards mining. I tried in stalling it to see if it would improve crunching, but the Radeon Settings window would just open up to a blank window and I need Radeon Settings to work because without it, the driver over-scans the screen and I need to set the HDMI scaling factor to 6 and to enable the Virtual Super Resolution for my TV/Monitor 1080p.

Thanks for that. Yea I didn't have a lot of time to look in depth on that board so I guess my original thought was right about CPU.

Minimum 3 PSU (betting would need more) so how to get them all to power on at the same time and off.

The youtuber that made that video talking about the board has also made one showing a thirteen card rig that he made. Apparently, the newer power supplies come with link from the main 24 pin connector that can turn on the other supplies.

Just checked Guru3d this morning and found this article: {url}http://www.guru3d.com/news-story/inno3d-warns-that-mining-can-break-warranty-on-their-gpus.html[/url}

Wonder how long before other GPU manufacturers apply it and will they apply it to scientific computing?

The easy way would be to buy premade switching devices.

Took a look at the article you linked to, and a couple of the comments probably have it about right. First of all, how are they going to prove you were mining with it? Next, my guess is that it wouldn't effect the 'normal' users or small time miners, but those who like were mentioned might be trying to RMA 50 cards at a time could be in for some difficulty. My guess, if the RMA situation gets too out of hand for them, is that they will just cut back the warranties substantially. Maybe down to one year? :-/

After watching his video about building a 13 card rig for mining, I thought wow, that would really make a nice crunching rig, but one would have to have a second job just to pay the electric bill.

So it looks like only 1 manufacturer is doing this so far. It would really be hard for EVGA to do this as they have an actual Fold@home team where they actually encourage them to fold on their cards.

They also say the lifespan of a card worked 24/7 is a year, I would think someone who knowingly runs it 24/7, combined with high temp, failure to maintenance, wouldn't be surprised if it gave up the ghost after a year. Of course, most people will maintain their cards, doing the most to dissipate heat, regularly clean them to extend their cards.

I think it's unrealistic to think after a full year at 24/7 there wouldn't be some failure rate.

Oh well, I lost my train of thought, lol....

My question would be could you get that many cards to fit on the motherboard? I guess you have to be assuming the "extender cable" thingies because I don't see how you could possibly fit even a "mini" card onto 3 of those slots in a row.

If you assume one thread per gpu task and hang gtx 1080's off it. Apparently they run 3 tasks. So 19 X 3 = (starts counting on fingers and toes )[oh, there is my Windows calculator] its something like 57 threads you would need for "full production" under Seti at least.

So without even examining the under pinning hardware lanes etc I would find it hard to believe it would be a good idea for Seti at least. Unless the SOG code could be re-written so it doesn't require the full attention of a core / gpu task (is that what the Cuda80/Alpha test is about? I have lost track).

I don't remember if I mention it here but I think a Threadrippper version of this card would be AWESOME......

Then there would be 32 Cores and at a max PCIe 60 lanes available (best case)...

Yes, the amount of core required would need to be dramatically reduced.

To connect all those GPUs, you would need risers as pointed out in the article. Something along the lines of

https://www.newegg.com/Product/Product.aspx?Item=17Z-00AT-00005

Never tried those but I think it would work.

Power ( it always comes down to power) is going to be the big issues. 1080Ti require at least 8+6 pins, unless you go with the FTW then 8+8 . That's a lot of PSUs

For a system like that, a whole bunch of 3GB 1060s would give plenty of output, and not require too much power to do so.
