Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[TechPark]

Please Help me!!!!

Im have one Motherboard gigabyte 790A-DS3P and two sapphiore RX470 OC of 4gb
im using windows 10! with one cards all works fine
im put  the 2nd video card! all is ok
the pc recognize the 2 video cards
And when starting the claymore's the pc shutdown
what im need to do ?

In this vídeo of youtube this People use without problem

Your PSU is not good. You need to get a proper PSU with PCI-E connectors.

If I were you I would use DDU, uninstall the drivers and reinstall 15.12 drivers only.


what is DDU?

ALSO HOW I CAN INSTALL 15.12
because i can not install these version of drivers?

I believe you should explore Google before your invest in mining. All your questions had been answered thousand times.

I love this website for these types of questions.

5x R9-390's at stock settings will use about 1300-1400watts.
Unless you're using a perfectly running EVGA 1500 your power supply could be the issue. Most power supplies don't even get near their rated power.

Best thing to do is to have them adjust after bootup to max undervolt and  see if they are more stable.

Buy a dps 2000bb and your problem will be over

Useless without 240v.

and they dont have the correct connections to power a standard mother board

That's no problem.  If you run 2 rigs you can grab 2 500w PSUs to power your boards ($70) and then a dual dps2000 package complete with cables, breakout board, and power cords ($220).

I'm not affiliated with these guys.  I just ran across their stuff when I was running S7s.

If you only have a single rig, just grab a single 500W and look around for a single dps-2000 with breakout board and cables.

ATX PSUs get stupid expensive as you start looking north of 1000W.  4KW IBMs for $220?  That's a steal.  My EVGA 1600 was $300.

how did overcome the 8 pin connector on vga cards that require it

[forzendiablo]

im sure 280x can be pushed above claymore, can u do it for us oldschoolers?!

You can either swap out the cables for 6 pin VGA to 8 Pin using a better gauge or use adapters.  The cable route essentially turns your cables into 1 long adapter and is far more cost effective.  If you already have a ton of cables laying around the adapters would be cheaper than replacing cables and you can get a deal if you buy in bulk.

All said, you can get 5KW of total power output (2 500W ATX and 2 dps-2000s) for ~$300 if you're buying from scratch.  Might get as high as $350 if you need special cabling for R9 rigs using 8 pin power.

Edit:

Keep in mind, you also need to power 5 USB risers on a 6 rig setup and/or power the pcie slots.  Some 500W PSUs won't have the configuration requirements necessary which may push you into something bigger.  Even so, you will likely walk away with a much lower $/W ratio using a combination of ATX and server PSU.

Friends using a dps 2000bb 6x r9 280x only in the gpus and normal psu to connect the board mother and riser everything works normal for more than months

Claymore; are you planning to fix the stability issues in 9.1? my rigs are still crashing in this version but work fine with 8.0.

They question has been answered already. There's no issues with the miner. Make sure your PSU's have plenty of capacity or downgrade to v8 as future releases will probably push GPU cards more.

Sometimes can help driver uninstalling after DDU cleaning...
btw i have 2xCorsair cs850m for 6xSapphire 390 - -30mv at the afterburner power consumtion 1140 core and 1500 mem. -1830 sols with -i 6
This rig always starts ok and crashes very seldom - 1-3 times per month

On flypool they use fix difficulty (2000) for default setting. You can set it manually in password parameter.

Should I set the diff higher for a 6*RX400 rig?

Is vardiff better than using fix difficulty?

[adly3000]

Thank you very much..
I noted some miners said not to use the sata to molex!!!
and if I used the sata to molex cable then I have to connect the (8pin from the PSU to the molex) which have 3 molex in series without issue!! If yes that means that the last sata (first on the last GPU side) draw 50-75W but the previous will draw double(as it is connected in series) and then the first sata (PSU side) will be tripple power.So it will survive!!!
Thanks.

It is better to use Molex, but you will be limited by power supply.  So it depends on card. Reference 480 draws too much from PCIE slot, so would be an issue. As long as the card isn't taxing PCIE slot (realistically best at 66W or less, but card can draw 75W per the spec), it should be fine.  Compare typical power usage of card to its power delivery. RX-480 reference uses ~165W, but only has 150W of inputs, by specifications (75 from 6 pin, 75 from slot).  Any 480 with 8 pin should be fine (150W + 75). I think 480 was meant to be 150W card, but they upped clocks to be competitive with 1060, right before launch, so 6 pin isn't really enough.

Thanks again..
My cards are 11260-01 rx 480.. So I can connect the EVGA 1300 G2 pcei 1 for every card of the six. and use the 2 cables which have 3molex and 2molex to supply 5 raisers and 1 sata for the last raiser..
Will not have any issue while the molex are series connected!!!!
PCIE ]-----150W--------100W---------50W----
                           |50w         | 50w         |50w
                       molex1        molex2     molex3

You shouldn't connect more than 2 cards per chain from the PSU.  So I would do 2 on each molex cable, then 2 on a sata chain, or 2 sata chains.  I actually do 1 on each molex chain, and 1 on each sata chain, lots of extra cables, but shouldn't overload any of them.

Thx mate got it.

That is right. You can underclock or use a more powerful PSU or reduce the intensity level. It solves the stability issue.

For the 6X RX 400 cards, it is better to use the default 2000 difficulty level so you send out one share about 1.5  second.

I would say measure the output at the wall of the 390s using a kill-a-watt. The're cheep, every miner should have at least one. I don't have any 390s myself, yet(getting a 295x2 tonight) but they say they pull around 300 watts. If this is close to true you need another PSU to take the load. Keep in mind if your on the 120v North american standard your close 15 amps. Most households use 15 amps as the standard for each circuit.

If you want to try to change the core voltage or lower the clocks to save power, or take one of them out of the rig and see if it still crashes.

 R9 390 was a rename, a bios update, faster "default" stock clock, and a bit faster memory vs the R9 290 - my 290s pull close to 300 watts with undervolting via TheStilt bios upgrade but significantly overclocked while mining ETH, should pull a little less on ZEC even with v9.1 Claymore.

 The largest capasity ATX power supplies I am aware of are rated for 1600 watts at gold efficiency - and will push a standard household 110V 15 Amp US power circuit AND the outlet right up to it's max rating if the PS is 100% loaded. NOT a real good idea for a miner, you need to allow some "derate" for continuous usage.

 Higher capasity server PS are ALWAYS designed for 220v input - and tend to be derated a lot on max capasity when used on 110V input IF they work at all on 110.

If I were you I would use DDU, uninstall the drivers and reinstall 15.12 drivers only.


what is DDU?

ALSO HOW I CAN INSTALL 15.12
because i can not install these version of drivers?

 IMO on Windows go with the 16.10.1 drivers, they support all current cards and work with equal efficiency as the 15.12 drivers.

[QuintLeo]

Guys, what are you using to switch between zcash and the other coins automatically?

Maybe someone has a way to switch coins using only claymore's miner?

 The only "automatic" switching I do is the machines I have running NiceHash.

 Otherwise it's "whattomine" early in the morning with a custom hashrate setting bookmark, and manualy switch if profitability has changed enough to matter.

[QuintLeo]

What kind of hashes should I except with r9 270x 2gb?

This are actualy prety good..  135 - 140 sols - v9.1. Good ratio w/sol.. Specialy if undervolted

138-140 me too for 270x

 The R9 270x was a rebadged HD 7870 with faster RAM.
 I see 125-130 on my HD 7870s with v9.1

[QuintLeo]

NVDIA's miner did huge progress. Worry they will be better for ZCASH mining. Lots of AMD users may be upset.

 On a $/hash basis, Claymore v9.1 on my RX 470s leads the Nicehash eqm miner on my 1070s by a fair bit even though I haven't worked with settings on the RX 470s as much - but the advantage got a LOT narrower with the .3a eqm version, and the 1070 does win now on hash/watt by a narrow margin if you aim for max efficiency.


 I don't think the AMD fanboys have much to worry about, nor do the NVidia fanboys have a lot to crow over.


 Just out of curiosity though, I would be interested in seeing what a Titan X Pascal could do on sol/s. 8-O
