We're gonna get banned soon for mentioning piracy. I was thrown off windows10forums.com for saying "Piratebay".[/quote]

Probably....so today I tried a different combination of Nvidia 760 gpu's in one of my test machines and it worked, I have 3 760 gpu's totaI, got 2 gpu's to work without having to reinstall Linux Mint 18.3 and it auto picked up the gpu and used the same drivers as the existing 760 in the machine. It's now got a boatload of MilkyWay gpu workunits to go thru at about 9 minutes each. I did put a dummy plug on the 2nd gpu this time, I didn't last time, and it booted right up finding both gpu's with no problems and no black screen this time either. It's now running 2 MW units at the same time and 3 cpu workunits from ODLK1, Latin Squares, on the other cpu cores. It's an AMD 6 core cpu but I always change it to use 1 less than the max cpu cores to reduce the load on the pc, so it's running 2 gpu wu's and 3 cpu wu's.

A 760 has slow double precision, you'd be better off doing a single precision project like Einstein or Seti. My AMD 280X cards which I got for £45 each do a Milkyway unit in 30 seconds each.
Your cards are just over half the speed of mine at single precision, but only a tenth of the speed at double.
This site is a great place to see the double and single speed of any card: https://www.techpowerup.com/gpu-specs

So have you not got the third card working?

Lately I've been doing more Linux pc's as pirate versions of Windows don't always work forever, I just can't afford to spend the money to put Windows10 on 17 pc's!!! I've done some trial versions and buy online numbers but here in the US they often get cancelled eventually.


From my experience most motherboard on the eBay market can run Win7 usually without a bios upgrade and be upgraded to win10 at no cost. No need for any pirate stuff unless you are buying brand new motherboards. If you can afford new motherboard with UEFI bios, new ram, new graphics,, etc you should pay for win10 if you plan to use it. On the other hand, for used motherboard:

If the motherboard ever had Windows 7 as an OEM install (HP, Dell, Toshiba, Asus, etc) then Win7 can be activated using the OEM serial as (unless things have changed) the license always goes with the motherboard. The is not a "dark web" thing, Microsoft has a public repository for windows ISO DVDs and keys show up using google.

If the motherboard ever had OEM Vista then those OEM's that offered a free upgrade to 7 (way back then they all did) have a BIOS upgrade that can be downloaded and installed to get you Windows 7 assuming you can find it. I have not yet found a Vista system that cannot be upgraded free to Win7 and then to 10 though it may run terrible or not at all.

If the manufacturer (eg: MSI) never had an OEM license but the vendor (Dell, etc) sold the exact same MSI board under the Dell name (or HP or Alienware), then the Dell or HP or Alienware bios can be installed and win7 enabled. This is typically a replacement motherboard for a licensed system done at a repair depot but can be done at home if you can find the bios (usually at Dell). From my experience, Microsoft allows one free motherboard replacement (vista, 7 ,etc) Assuming it is not a new motherboard you tell them (you have to phone in) it is a replacement. This only works once and you have to know the OEM serial key and it must have been licensed previously. Usually, if "used" there is a good chance it was used with a Microsoft OS.

In case of doubt, download and run "SLIC_ToolKit_V3.2". If it reports "2.1" for the license then win7 works. If it reports 2.0 then Vista works but you can probably find a bios replacement to 2.1. If nothing is reported you cannot legally put in a 2.1 bios.

I thought the free 7 to 10 upgrade offer expired long ago?

And if you don't like idea of a pirate Windows 10, you can actually leave it on trial mode indefinitely if it's just for a cruncher. It only nags a little bit and disables a few fluffy features like wallpapers (which you can actually fix in the registry anyway!)

All that is cool and I will try some of it, but I didn't mean 'they won't run Win10' just that it's not 'worth' running Win10 due to the older hardware and the overhead Win10 adds to them. They are a good 12+ years old now, not for me but since they were first made and sold and although they are decent crunchers they aren't fast at anything even when they had Win7 on them, which they had when I got them from a reseller on Ebay as "off lease" machines. They have dual quad core Xeon cpu's in them making for 16 cores thru HyperThreading but only run at about 2.4ghz each. I have 5 of them but one was retired this month as I got an AMD ThreadRipper 1920X which has 24 cores thru HT and runs at about 3.4ghz. Don't get me wrong the 16 core machines crunch just fine and bang out workunits 24/7 but what their strongsuit is quantity not speed. They each have around 20gb of ram and a gpu that crunches too, anywhere from an AMD 480 to an Nvidia 1060. They are JUST crunchers and only go on the internet to support that or the a/v software, the backup software I use or a couple other programs I run sometimes to see how they are doing.

I wasn't aware Windows 10 "added an overhead". If anything machines run faster with 10 instead of 7. Anyway that's just launching stuff etc. When it's sat doing nothing but a Boinc project, I doubt the OS you're running makes one iota of difference to the speed. I put Windows 10 on everything to make it easier to get drivers etc. I have actually got a genuine license sat on that shelf over there, but I haven't had to use it yet....

I have over 500 million credits on Einstein and only just under 400 million here is why they are here.

And no the 3rd card is on the shelf right now as I don't have another pc to put it in right now. All 3 were on the shelf as spares until I replaced the pc they are now in and started using it as a test machine for various versions of Linux. The 760's are my next to slowest cards I have left, I have 6 750Ti gpu's but I'm also building a mining rig that will probably be used to crunch MilkyWay units as well. Both can crunch Collatz units too but neither is very fast at it with the 750Ti's taking about 40 minutes per workunit. Both can zip thru some PrimeGrid units too but I'm just under 500 million credits there.

I just got my 4th computer crunching. A laptop given away for free because it "wouldn't start". It works fine, it just needed a new hard disk. I managed to connect a desktop hard disk to it with an extension cord and an external power supply (laptops don't seem to provide 12V on SATA). When I eventually receive the mini-PCIE to PCIE riser, I'm gonna try connecting full sized GPUs to the poor little thing :-)

You can get a 240gb SSD drive for about $50 these days and that thing should zip right along, you cangeta120gb for even less but Windows10 stores ALOT of crap on the pc so will fill it up pretty quickly. Mine filled up with 'update stuff' that it then doesn't delete after it's done updating, so I went to 240gb drives and haven't had any more problems.

Right now because the motherboard doesn't support 3 pci-e cards. The card works on it's own but it didn't work with another 3 fan 760 that's in the pc now. Right now there's a 3 fan 760 and a single fan 760 and both crunching just fine, when I put both 3 fan 760's in the machine it didn't like that. The 3 fan gpu's take an8 pin and a 6 pin power plug while the single fan 760 take 2 6 pin plugs. I have a power supply tester but it doesn't test the 8 pin gpu plugs, all the 6 pin plugs test fine though. I even swapped power supplies and it didn't make any difference, I have a 900 watt one in the pc now but tried an 850 and there was no change. To me it really doesn't matter as the side of the case is off all of my pc's for cooling and the room is cooled to 82F. I have to shut the whole pc down before Wednesday as it's just a test machine anyway. It has an AMD 6 core cpu in it and Linux as the OS, it's the one I tested the different versions of Linux on.

I run crunchers with Windows 10 on 80GB drives and they're only half full. Not sure why you're seeing so much used space.

And I'm not going to spend money on a new drive which could be spent on more crunching power. It's irritatingly slow to set up, but once it's just crunching away, it doesn't need a fast drive.

Is this a power problem or the motherboard won't take 3 cards? What sockets are you connecting them to? Even my 12 year old board is accepting two cards on one x1 socket.

Try two PSUs, that's what I did - I used the first PSU for the computer and one GPU, then the second PSU for the 8pin connectors on the 2nd GPU. And you don't need a special tester, just stick a multimeter on the 12V connectors when the cruncher is running. In fact one of my PSUs is rubbish, it only supplies 10.5V under a modest load, but the GPU doesn't care, as that voltage is converted down to about 1V for the chip anyway. I've never known any chips get upset about a lack of power. If you overload a power supply it usually cuts out or goes bang.

The motherboard doesn't have another pci-e slot in it and I really don't need to do risers to get this gpu running. I have 16 p's crunching right now, counting this one, so this one isn't a big deal. I have 6 750Ti's in a mining rig I'm working on when it's not in the 40's and 50's in my garage and I have 4 other gpu's sitting on the shelf that were replaced because I got better gpus's, that number includes the 3 760's. My wife complains about the electric bill now so running every gpu I own 'just because I can' doesn't make sense.

Well if you're heating the house, then call the computers heaters :-)

Probably too late now, but in the UK we had a ridiculous scheme to have solar panels fitted to our rooves. We could actually end up getting paid for generating power, AND get to use it for free. Yes, we were getting electricity at a negative charge :-) Anyone who joined the scheme when it was there still gets the absurd tariffs :-) I know a farmer who filled an entire field with solar panels and makes more money from that than he ever did growing crops.

The UK is now one third powered by wind, I'm hoping that when that's 100%, that electricity will be dirt cheap, we're still paying for the creation of the turbines.... once they're all up and running, no fuel cost :-)

Problem with windmill in the north sea

Australia had same problem: Solar farm failed to notice clouds approaching and didn't know what to do when power went out.

I really don't understand the problem. We have a national grid, which is then connected to other countries too. There's several different renewables which operate in different conditions, plus non-renewables. There should always be enough of something generating.

As you say the problem seems to be the plan when the wind stops or it's cloudy, if you aren't prepared for it people will sit in the dark and be very mad at you.

Here in the US it's similar and we do have a fairly robust grid where if one part of the Country goes dark it can come back online fairly quickly IF they turn it back on. California has a whole other problem in that their distribution plants are in such bad shape they are CAUSING outages, so even if they go down they can't flip the switch to get power from somewhere else because of the infrastructure problems.

In my individual case I have a backup generator so am not ever without power unless my 250 gallon propane tank gets empty, yes it's big enough to power the computers and everything else too but once it does come on I leave all but one or two of the computers off.

AFAIK, the UK's national grid doesn't require intervention. It's basically a huge grid of 330kV lines, which every power station feeds into, and every town takes from. The national grid workers monitor the usage, and command power stations to turn on and off to maintain the correct voltage, frequency, and current. We can also buy or sell to France and I think Norway.

One of the countries in Europe is 100% wind (Netherlands?), so I guess they do a lot of trading over the borders. Easier over there since they don't have to send it across the sea.

I have a UPS which powers my main computer, all the lights in the house, the internet router, the TV, and the stereo. I have never known an outage longer than 30 seconds here, so I haven't even added extra batteries to it. I would if I started getting longer cuts. And I'd get a UPS for things like the fridge and freezer. I only got this one to stop data corruption if the power goes off for a few seconds, plus the voltage here isn't very stable, so it adjusts that too - my lightbulbs last a lot longer.
