Seems that nVIDIA and Intel are poor Cryptominers.... Why they are so poor in that aspect compared to AMD? What feature has AMD to have outstanding values?

Have you set Power Efficiency to Off? If that doesn't help you may have to rollback.

I spaced that they put that into the driver. I tested with whatever the default value is. I'll retest when I get home.

So, i tried to use those drivers, but they don't support 980ti's. So i tried the oldest driver that did with no luck. I'm confused, because i absolutely had my 980ti's mining at 21 m/hash apiece on windows 10, so i have no idea what changed. I also made sure windows 10 isn't auto-updating drivers.

I eventually gave up and installed ubuntu. I finally got it working, but that stuff is rocket-surgery to get set up.

Dude, it took me like 2 hours to get Windows 10 to stop updating the driver automatically. I had to use powershell and gpedit and a special microsoft tool that lets you hide updates. But there's a raft of problems if you don't do things in a specific order the card will eventually update itself. It's been 2 days now and no updates so I think I finally got it.

That driver is very old (Feb 2015?) and was only meant for an old RC for Windows 10 so I'm not surprised you ran into issues with your 980 Ti. I haven't tested gaming yet but I also wouldn't be surprised if newer games don't run at all on my 970.

For Geforce cards you're better off with Linux. The only reason I stuck with windows 10 is this is my HTPC so it's used by my family for other tasks (Netflix & Youtube, light gaming). I also had to set powertune to 65% (the lowest MSI afterburner would let me) to get the card to operate quietly enough and I had to use really small work values to keep everything responsive on the desktop. I'm only getting 15MH now but at least it's all running smoothly now.

How many MH do you get in Liniux?

Actually Nvidia cards aren't so bad with Etherium mining. They just suck under Windows 10 compared to AMD cards. The power efficiency of an undervolted and tweaked 970 is on par with the better AMD cards.

The issue is one of cost. You can get a Radeon 380 for roughly $150-175 less than a 970 and they'll perform roughly the same once tweaked. But if you already have a Geforce 970+ there's no reason not to mine Eth on them.

On side news I reflashed my launch blower powercolor 290 to 290X and started mining on it on the other comp. -19mv and 52% fanspeed, it still throttles a little, around 950 MHz. Getting about 26MH/s from it.

Nice! that's not too far off from a tweaked 390!

FYI I did more power tuning last night on my rigs. My new 380 isn't responding well when overclocked. I'm averaging about 20Mh which isn't bad but I was hoping for a bit more. Given the price they perform well especially undervolted though.

I have my Dual Fury X's down to 510-520W on a power hungry X99 platform. This means each card is drawing roughly 200W each. The two combined I'm still getting slightly over 60Mh which seems like a reasonable trade-off for what I pay for electricity. I'm sure if I undervolted and underclocked the GPU/Memory I could get them down to under 175W each and still be around 50-55Mh but I'll leave that testing for another day.

So far my 390 is the champ efficiency wise. I'm able to run 1100Mhz, 1500Mem with core voltage set to -100! and powertuned to -20. I haven't measured at the wall yet but according to GPU-Z I should be around 130-150W and I'm still getting 30Mh on the card. I could just have gotten really lucky with this card but I have another 390 (same model) being delivered today so I'll be able to compare them. I'll be super happy if I can build a 60Mh rig that draws under 400W.

My main rig with 290CF is running W10 soley because of DX12, and its a nightmare for mining. Getting Windows to not automatically install updates is a huge PITA, but it's pretty much necessary if you don't want to come home from work and find your computer sitting idle at the login screen every 3 days after updating 12 hours ago.

I'm in the same boat. I want DX12 (I just got a Hitman game code!) and be able to mine. Microsoft is making it very annoying for us to have our cake and eat it too.

Is it normal for the mining pool dashboard to be all over the place in regards to MH/s compared to very consistent results using the local benchmark? On the 380 I'm getting results varying from 3 MH/s to 35 MH/s from the dash, consistently 20-21 MH/s from the benchmark tool (and looking at the hash rate on the console).

Yes this is normal for PPLNS enabled sites. You need to look at the trend over a few weeks to get an average of how your card is really doing.

Here's a description of how it works:

"PPLNS is a way of determining how many cryptocoins you get for your shares completed. Pay Per Last N Shares is what PPLNS stands for. This method of calculating payouts includes a "luck" factor. Using PPLNS your payout per share will have a large range (30% more or less on your payouts), but on average, PPLNS earns more than PPS (by 5% or so) in the long run (a month or more).

PPS is also known as Pay Per Share. It is a more direct method where you get a standard payout rate for each share completed. This method eliminates the "luck" in your payout, but can decrease your total income per share by around 5%. Using PPS you get a set number of cryptocoins per share of work you have solved. It has no luck involved so the payouts do not fluctuate."

You rock. Thanks.

You guys should complain to AMD about W10 mining. Someone needs to kick them to get them to support the market. They can be as dumb as a bag of rocks marketing their product.

Is W10 that bad? I've been using it since July and I think I might have done something to turn off those auto updates, but I definitely haven't had issues like you guys are describing.

Nvidia is worse under Windows 10. Geforce cards consume about 15-20% of CPU time with eth mining vs a few % for AMD cards.

The issue here is Microsoft with taking away control over how updates are delivered.

It's a maddening system, and it's really completely unusable for anyone who actually does work on their computer. Without completely messing around they best you can really do is just schedule the updates to a certain day, and then hope you don't need to be doing anything that night and make sure you save and close everything. For a lot of the stuff we do at work where computers are on 24/7 connected to hardware and collecting sample data, it's completely unacceptable.

I found the group policy change to force the updates to notify only didn't do anything. The only thing that's worked so far (knock on wood) is to deny Musnotification.exe read and execute permissions.

They get 21MH apiece at stock clocks. I haven't messed with overclocking them.

You can disable everything using Ultimate Windows Tweaker app.

I haven't tried that application yet (looks like it hasn't been updated since the big November Microsoft update) but I generally stay away from any app with the word "Ultimate" in it. Also a cursory look at the app shows nothing to prevent unwanted driver updates.

Anyways, you can fix the driver issue manually and perhaps I'll write a short guide on how I was able to disable my 970 from updating. This does not prevent regular security updates and unwanted reboots though, just driver updates.

No luck with shutting off the 16.3 power efficiency toggle. Still stuck @ at 25 mh/s max. Average is between 16-20. I'm going to do some more tinkering over the weekend to isolate if it's my machine or the drivers. I DDU'd before installing 16.3 so I doubt it's the machine.

Check out the difficulty curve....

This party is going to end soon unless the price of Etherium goes up in lockstep.

Depends by what you mean by party, and soon. The insane profitability might be gone, but baring ASIC or FPGA intervention even great than tripling of HR would still give great returns. 100MH/s still returns $227 per month at current prices, and assuming that takes 1000W and you pay 10c/kWh that's still $150 in profit.

I don't pay much attention, but barring a shift in technology I can't imagine the market moving too quickly past say the 4TH/s point. That's the equivalent to more than 100k additional 390s pointed to Eth. I'd have to imagine everyone who had a Litecoin GPU rig has long since moved it over, so pretty much anything else would be new stuff coming online. It'll obviously get there, but it might still take awhile. I'm guessing at least a few more months of good returns.
