Also:   Any special edition cards such as "OC" or "SSC" should never be overclocked.   The manufacturers have already done the legwork for us for the max reliability/stability on their card build.   Keep this well in mind.....   I never overclock a SSC or OC edition card.

This is the problem with installing more than one GPU type per system:

You'd have to do a nvidia driver "clean install" for the device's specific driver to fix that issue.....  Which would remove the other versions of the driver for the other cards........

Any chance on getting the 2 970's in their own box by themselves to test this?

so are S7 users saying turning ES off and throwing diff < 8000 will limit the antminer freezing/not mining issues?

Altcoin mining will be more profitable until BTC > 750-950ish I think.  One effect of the halving.

Amazing hashrates with 980Ti.... I need to check on the 10 series.

I wonder what the 1060 does.  Price point would be nice if good hashrates =)

the earnings from lbry are sooooo much more than lyra2.... lol

and assuming no other miners have mined before there were no other miners..... then there are shares "in limbo" till the next block is found.

sorry, I meant when TTF is longer than 3-4 times the block find time luck is most present.   I totally botched that statement.

Yeah.  Pretty close description.

When pool hashrate gets past the point of most users only having less than ~2% hashrate, you really see consistent payouts and the luck factor doesn't really take effect.

Pool luck is a real thing.

Pool luck is amplified by smaller pool hashrates when block TTF is larger than confirm time...

Larger hashrates not only slow the network for your pool (via diff), but they do for all pools as well.

The payout to the extra miner in the end, means less payout to the other miners in the beginning.

Once pool hashrate grows beyond a certain point, pool luck is even with the rest of the network for the most part.  Luck, can be applied as an inverse scale from the point of TTF=greater than confirm time; all the way to zero hashrate.  It's hard to explain this last concept without a picture, but i am in no state to draw a picture.

anyone else here get the impression that exchanges like Coinbase purposefully devalue the currency at the end of each month to take extra advantage of people having to pay re-occurring bills?

I have noticed this trend stay consistent for quite some time now....

We lost about 3Gh on lbry; some of the big hitters didn't like not getting a block asap... lol.

Thats fine.  My share % is still rising   Who else is at it with me?  My one video card is like 20% of the current pool hashrate of 6 total miners.... lol

im gonna treat this like decred for a bit.... at least a few weeks to get the profitability estimate in the block gen time scale.  I'll stay on it solid and assess if the profitability will remain high, or if I should just consider it good luck and go back to the multi-algo slow and steady route..  5% of a LBRY block is a payout... so that's all fine by me.


I am almost ready to say eff it, and go drive to SF and grab that 960 that's waiting for me.  Getting ancy.

Just saw this.  Still need to watch, but maybe might be something u want to look at given the title....

Glad to help.

Ive noticed most people reporting issues have been with the middle model cards (970, etc)... so I tend to stay away from them myself.

Its almost as if the 70 model is a batch of high end chips that all the cuda cores didnt work on or something, so they make that die work at a lower rate with less cores and not loose manufactured but failed high end product....

Cant wait to get up to SF and pick up that 960 off the shelf and get it back to work.   We took that duck 960 machine apart to build out a system for a customer and the second video card had been sitting waiting for its new home.   He planned to go 10 series on the next machine, so its not a big deal for him to trade me 2 power supplies for the 1 card.

I'm running 1.8 Dev and am seeing advertised hashrates on my GTX980.  Seeing the 980Ti hashrate makes me wish I had splurged and been poor for a few weeks to pay for the upgrade... The Ti having nearly 66% more hash on lbry compared to the 980!

But luckily last night I struck a deal with a friend to trade a 1000W and a 750W power supplies for a barely used EVGA 960 SSC (superclocked)..  SO im very happy about that trade and the bump in hashrate that my home machine with the 980 will get

~158Mh.  Its an Asus GTX 980   Check the benches for my specific card by: Clicking here.  Its in P2 state.  You may have been right;  im stepping away from forcing P0.  Allthough, my watercooled GTX 480, it has no P state problems.

Funny thing is:  I can mine at default intensity (20) and still play games such as League of Legends on max settings in 1080;  no hiccups, no stutters... pretty impressive profitability and usability.   neoscrypt hammed up my card pretty bad... intensity went down to 15 I think.

switched to LBRY last night.  Wanted to see what all the fuss was about.

Looks like for the time I was on the last block, I got half reward as shown.    Should be double for the next block if pool hashrate stays about the same.


I like those numbers.....  Hopefully pool luck stays in the green

Yep;  that's what I was thinking.   When you start drawing too much, internal voltage drops and amperage turns up.  This causes more heat in the components and a snowball effect ensues.

My comment about several 50A rails was literal, and is a pretty close and very realistic situation.  When I give these values, i'm not joking.... They are coming from my Coolmax 1600w.    I know the math says there's ~1920W of just 12v power available (E/I*R) cause the sticker says 110A and 50A of 12V power:  But the sticker, shows that its only allowing 1600W total from the PSU; with a max of this, and a max of that on each designated supply line (12V#1 and 12V#2 are stickered to be a max draw of 1560W even though the math of E/I*R says more).  

I have seen a few people burn down S7's and S7 power supplies because the the two sets of PCIE plug rails were only capable of 110A total when they were under the appearance of being both separate circuits;  Yet the power supply said there was another ~40A of overhead. (1560W of 12V between the two is available total if you trust whats on the sticker)... This is not an 1800W power supply;  but it allows for a total of 1600W to be drawn from it across all voltages in a combination which allows a massive; nearly 1600w of +12V usage in theory.  The problem is 12v rail 1 only supplies PCIE (110A), and 12v rail 2 only supplies the motherboard plug, CPU plugs, and accessories such as SATA power and the like. You would never know this is true unless you took it apart.  One of my coolmax PSU's are from a person that burned down an S7 drawing too much from it.   I had to open it up, and hack-job-rewire the modular plugs in the back of the PSU to bypass and cut out the old melted PCIE cable plugs and fix the remaining good ones to have a good usable PSU again.   I will also rig up some PCIE plug adaptors to utilize the FDD/HDD power ports, and the motherboard connectors as well.

To finish:
You not only have to obey the sticker, but you have to use a little extra sense when trying to figure it all out.    Don't ever assume any one thing is correct unless its totally verified

AFAIK=as far as I know

If its a temperature problem, theres a system level component that's having an issue I would think.

Run a motherboard monitor and CPU monitor.... but a voltage issue could still be the case.   I hope you are figuring your power availability per rig @ 120-160% expected draw?  If I ran a 4 card machine I would be for sure running a 1600w power supply..... 

I wonder if you are drawing too much +12V off the same rail that supplies the processor and are causing this all to happen.

I have seen many strange configurations once opening up power supplies and seeing what is tapping which available rail.  Many PC power supplies have 3-4 independent +12V power supply circuits at roughly 50A each...  give or take....    As far as knowing how they are distributed...... you have to open the power supply often to know the real truth...   

You dont happen to be CPU mining at the same time are you?
