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

[AzzAz]

I have 2 Rx480 and 1 Rx470

Working perfect with one card directly plugged into pcie x16 and 2 usb powered risers

Now I bought another Rx480 with usb riser

So my problem is with 4 cards plugged into Mother board PC (Win 10) does not boot...
Fans are spinning on all 4 cards
Anybody know why??

Maybe its because of PSU?
Its 750 Watt

I have to undervotlage my 4xRX480 4GB to run from a 1000W PSU. Really can't see how 750W would have a chance.

Im underclocking and undervolting so I wont have more than 550 Watts at the Wall with 4 cards.

But maybe PSU checks before booting and says 4 cards are too much? Is that possible?

No. Reinstall driver.

Reinstalled driver..but still same problem
Any idea?
Is there a Problem with amd crossfire?
Its 3 way so maybe thats the problem

Disable crossfire, useless for mining.

Tried diffrent drivers on my R9 Nano. No "asm" so no speed update... Funny that 290 and 7950 work just great

As mentioned above, use 16.3.2 with fijis.

You get interessting result with this driver on R9 Fury family ?
I got 9 x R9 Fury something like 330-370 H/s (-45% power limit)
With -asm 0 -a 2 parameters.

400@-96mv with 16.3.2 lots of nanos, pro duos...

I can confirm that the Pro Duo's work with the 16.3.2 driver and 11v asm 0.

I am running it at +7.1% and I am getting 420-425 Sol/s per GPU.

You should get almost twice that with a pro duo? People are seeing them figures on a nano.... anyway what did you use  to undervolt the pro duo?

[H0RV4T]

I think you can try 400H/s from single graphic card.

No doubts it's possible. Question is how do you like more energy consumption? If you can caary on, let's give a sign you made it.

Any suggestions for 400h/s? What do do to get this numbers?

Im mining at  coinotron, and im getting the best result so far

Soo, there will be a new version this weekend?

lol I run 8x RX470s from a 850 watt PSU

[qqqq]

Claymore, why do you ignoring the Fiji driver issue in v.11? Do you have a plan to fix this ?

Why do not you tell people how much you reduce the clock speed graphics cards?

[kev7112001]

4 cards is to much for 750w psu A psu wattage is total of 3.3v 5v and 12v just because it says 750w doesnt mean u get 750w at 12v
and im sure its spit rails so u get even less amps through each pci-e connector. so really u have less than 750w cause some of that is used for 3.3v and 5v amps and the psu itself could be cheap garabage or lie about what it can do.
also they have circuit protections to so if u do get it up running soon as u started mining it would shut off

[kev7112001]

now with what i posted above u can run many psu's in a system no limit to that just jumper the power good signal(green wire) to ground(black wire) on the atx connector to turn psu on they also make ready made adapters that allow u to daisy chain multiple psus so they all turn on together when u hit power on pc

windows? I have 8xRx 470 but not boot black screen , 7x470 works fine

Hey man don't let the cat out of the bag

Claymore, why do you ignoring the Fiji driver issue in v.11? Do you have a plan to fix this ?

I'm already fixing it. And upcoming update will also improve speed.

per GPU

I did not Undervoltage as I don't pay for power on my workstation :-) But I can only mine 16h out of 24h :-(

Claymore, the speed for the Polaris RX cards is currently embarrassing compared to anything else from AMD or Nvidia.

When will it be possible to fix the speed on those cards?

don't confuse people.
I've got here 6 rx400 on 1KW doing just fine (the most intensive dual eth&sc takes up to 920W from the wall, ZEC is about 750W)
EDIT: undervolted to the very bottom ('bout 850mv), lowered core, 2K mem, bios mod

The problem can easily be related to the pcie lanes/resources availability, play with bios: disable devices, set lower generation for the slots, disable power savings, etc... Drivers setup in win can be an issue as well.
