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

[Ursul0]

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?

DDU

15.12 Drivers
http://www.guru3d.com/files-details/amd-radeon-software-crimson-15-12-driver-download.html

When asked what you want to install, make sure the only thing is checked is the drivers( I believe its the first box and there is one you can't uncheck)

I would also remove the profiles in Afterburner. C:/~Program Files/Atiafterbuner/profiles (something liek that)

Reboot

Even better: exctract the content of the amd setup file, select "Microsoft Video Adapter" choose update driver and point to the divers dir manually.

Hi, Claymore!
Will drop you in the near future a new version of your miner ZCash?
Can a little more detail about the stability of version 10?
Thanks  

I had random reboots on some of my rigs after updating to CZM 9.0/9.1. Try to underclock and undervolt your cards a little (for example I use my 470 4GB with 1200Mhz GPU clock + 1000mV, 1750Mhz memory clock + 950mV, and -5 for voltage offset in WattTool). That solved me the stability issue.

Thanks for the idea, but i have 6xRX480 and i feed with PSU SEASONIC 1000W Platinum! There should not PSU be a problem, but I do not know?

Use 2x 850w power supplies = 1700w, then you should not have any power problems.

I call bullshit. I've got 6 rx400 stable on 1KW PSU running dual eth up to 910W at the wall. Zec needs less ~20W/card
Lower your cores freq.

Question:   Which port is best on Dwarfpool, was using port 3335, was getting nearly 700 shares but moved to 3336. now getting about 200 shares, think i getting payed less too...

Any thoughts.......

Higher diff but the total undiff shares should be the same. In the end it all depends on how many cards you have.

Sorry for the off topic...
In case of 6x480:
can you please explain how you connect the evga G2 molex to the raisers?
are you connecting the molex which is in series to the usb raisers direct!!
If yes then I only see 5 molex (on two cables 3x1 & 2x1) while you need 6, or you use one sata as the 6th!!!
any help would be appreciated.

Don't connect more than 2 cards per power cable (I do 1 per, but you can do 2 with most cards). You can use the sata to molex adapter that comes with the usb risers. Sata power cable can handle less power (~55w vs 75), but should be fine with 480 with 8 pin PCIE power.  Reference 480s, or any with 6 pin PCIE power..... plug into molex directly, or undervolt/underclock and do Ethereum.

Those 200 shares are worth more than those 700 as the 200 were done with a higher difficulty.

I wonder how long before we'll see posts on dwarfpool "stealing my shares"?

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

Can you help a lil ? I have a error like this WATCHDOG: GPU 0 hangs in OpenCL call, exit . In 6x470 4g rig I'm not having this error (last catalyst + 1200w bronze evga psu) but in other rig which have 5 gpu 3x 390 2x 390x with cata 15.12 and 1500w power supply I'm getting this usally after 1 or 2 hour maybe earlier. No oc at all all of them stock. After i saw this error miner don't start and rig crash. Thx in advance.

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.

exctract the content of the amd setup file, select "Microsoft Video Adapter"


how i can do that???

Can someone post 9.1 results (hash rate and power draw if possible) for R9 380 stock and what drivers are best?

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!!!!
