I see your problem, you were allowing it to update. You can't allow any updates, of any kind. They write code into security and any other updates that resets your preferences and allows them to seize control of your computers. After certain updates, they install a fix that prevents you from doing a reset point. At that point, it's a clean install again from a install disc.

i think he was also (correct me if, i'm wrong Keith) using windows 10. which is notoriously hard to get it to actually block updates. windows 7 you can turn it off completely, but windows 10, without manual tweaks and registry hacks, the best you can do is "pause" updating for about 1-2 months.

all of my windows systems get periodic system images taken. that way if it ever gets corrupted, i can just reformat and re-image and i'm back where i was.

I tried to restore from the last system image which was only a week old. Recovery wouldn't recognize the image as valid. I always used the O&O Shut Up utility to block everything that Microsoft enables other than the security updates and Defender definitions. Didn't make any difference, the only thing I could have done was a virgin install. I knew from my first experience with the Windows 10 installation that it wasn't going to be painless OR a short process. At that point I said f*-it and knew I could get Linux installed in a 1/10 of the time. No trepidations or remorse in the decision. Been very happy with Linux so far. It just works. You can either let it update itself or say no to all updates. Your choice. M$ never gives you the choice and makes decisions for your computer based on their needs and wants, not yours. Enough heavy handedness by M$ to finally kick them to the curb for me. My $0.02.

I updated the OS to level 14 at about 2014. Ever since I have updated (manually) the GPU drivers about once a year.
I download a new development platform (CUDA) whenever it is released. Since 2014 that has happened about once a year.

To babysit a machine? No - never done that.

To babysit a highly overclocked development machine? Yes. I try to do that every day.

p.s.
On vacations when I'm away from my computer I call for my daughters to help me out if my computer has any problem. They understand reset button, BIOS and Linux boot-up, sudo, tsch, bash, !nnn, <tab> ...
Both of my +18y daughters went to Helsinki (400+ km south from here) to study general language, automation, artificial intelligence and robotics and other studies based on their personal interests. My two other youngsters are still under 12y. It seems (I can hear) they do know how they are going to spend their near future...

Running Windows 7 and 1080Ti you could run 3 at a time and get better output than 2 1060s.

If you want to learn Linux and handhold it everyday then yes, you could install Linux, install the special cuda app and babysit it for faster turn around time. (I'm more for install and forget, let it run on it's own)


. . While I have to agree that Linux would be a learning curve (and not without the occasional ouchie) for a total newbie, once sorted it is even more hands free than Windows. I only need to check the Linux boxes for fun and curiosity. If Ihad to go away for any time it would be the Linux boxes I would leave running

coming back to this for clarification.

are you saying to run 3x SoG tasks? i thought SoG used all card resources and 1x was always best? unless the 1080ti is just so powerful that it can handle that kind of load without problems?

Yes it can do 3 at a time of SoG. The cuda special can only do 1 at a time.(last time I looked). Still need cpu cores but usually isn’t a problem.

yeah, the system has plenty of spare cores. its a dual 12c/24t system lol. moving from 2t feeding 2x GPUs to 3t feeding 1x GPU souldnt be an issue. i'll lose one thread of CPU crunching, but i'm sure the GPU work more than makes up for it.

and you're right, Linux special app is 1WU per card.

. . That isn't an absolute, some ppl have done it. But I believe they found it did not gain them much or possibly any improvement in productivity. It is still more productive than Windows/SoG even pushing things to running three at once.

The special app uses a lot more of a card's resources at one task loading than even two or three SoG task loading per card from my observations. My observation is simply based on how much power a card pulls when crunching a task or tasks. I assume use of more power/wattage equated to more work done per unit of time.

I was looking at the GPU list and noticed that the GTX 1060 3 GB was showing a slightly higher index than the GTX 1070.

Anyone have any ideas?

I am wondering about the CPU Gflops listing vs. the Gflops I get for cpu processing.

What I am seeing for my cpu Seti Gflops is something like 25% slower than the number listed for the motherboard.

I think I understand that the number on the cpu list from the benchmarks that are run. But having our cpu apps run that much slower?

They're just numbers, and they are all just estimates.
What matters is how long it take to process a WU.

Message 1950185 - Posted: 17 Aug 2018, 0:36:09 UTC

I now have a theory as to why the GTX 1060 3GB gpu's index number has dropped on the Windows gpu list.

There are at least 5 overseas vendors (as well as some US-based sellers) of "Fake" GTX 1060 3GB video cards.

These show up in the Windows devices list as GTX 1060 3GB on my operating system Win10. They are being run by the standard Nvidia driver. They actually do have 5 GB of ram and actually do run.

They run like "models" of the real thing. 192 Shaders, 3 CUDA's instead of 5 (someone wrote me a message, I don't get what it means but I believe it). Speculation has it that it really is a GT 570/560/550. They trick the OS by running a "pre-boot" bios before the rest of the OS starts up. The card is running about 26 minutes on a SOG task.

I have now run the card long enough that the Seti scheduler just started shipping me CUDA 42 tasks again :( I have a used GTX 750Ti on order from eBay but it may not get here till Saturday. I have turned my "get new tasks" off so I don't get anything more, for a while at least.

I wonder if we can get eBay to ban all these sellers?

Thanks for the update. I watched a video on youtube from LinusTechTips that reviewed one of these Chinese GTX 1060 5gb models. They had a very cheap heatsink, but really did have 5 gb of ram. They were priced about $75 cheaper than a "real" 1060 during the mining shortage.

Interestingly, they were pretty close to the real 1060's on gaming benchmarks.

I have two variants of EVGA 1060s, one has 9 CU, the other has 10.
3 CU is far below a 750Ti with 5 CU.

those 5GB gtx 1060s are real 1060s. they weren't made due to any mining shortage, instead they were aimed at the asian markets to be used almost exclusively in internet/gaming cafes, which are much more popular in asia than the western world.

just supposed to be a cheaper card for a internet cafe business own to fill their shop with. that's it

When I took mine apart it doesn't have a "current" Nvidia cpu in it So I claim it is "not" a real gtx 1060.
