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

[Lucky - Luciano]

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.

lol I run 8x RX470s from a 850 watt PSU

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

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

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

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.

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?

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.

Actually if the miner to lunch without your under volt software you will get 1100+W watt from the wall .
I did a test run with 6 rx 470 4Gb Nitro flashed with modded bios , Core 1130 Mhz , memory 1900 Mhz with 1500 strap .
It had 1150+W at the wall using Evga 1300 G2 Gold .
Once the Wattool kicks in and it is down to 900W

You need to make sure that voltage adjustment software kick in before miner or set Bios offset

Before Wattool



After Wattol


Some Crap PSUs will be rated at 1KW and will shutdown before reaching 1KW at the wall , others have multi rail with power distribution

Thank you for the answer. I didn't know about that. Asked you in thread 3-4 times about that.

has anyone tried to unlock the 8 computing units that are rumored to be on the 290x?

[kev7112001]

there r no extra cores to unlock on 290x/390x

correct, just run the cuinfo. just investigating if the 290x can run as a 390x as is claimed

1150/1900 obviously custom bios undervolted etc. Still pulls 890 at the wall, but the point of my post is as long as you know how to balance rails and tune everything right there is no reason you can't run a PSU at its max capacity.

yes as they are the same just 390x comes stock with 8gb ram and a bit better power optimizations and higher default clocks
but yes u can use either or bios depending on card pcb and there are 8gb 290x's

mine is the powercolor first reference with 4 gig. Can I still do it?

I have the error with the program Claymore Miner v11.0 Beta
GPU0 t = 72C fan = 100%
ZEC: 01/14 / 17-20: 14: 51 - SHARE FOUND - (GPU 0)

¿Does anyone know what to do with this error? I do not have much idea to do about it, because I tried installing it on other computers with the same result, it is a 480 4gb rx and it is mining alone, help 

[gsarducci]

Hey Claymore and gang.  I've got a funky one for you...

(tl:dr? Go to the bottom for update.)

So I just cobbled together this 4 card rig.  Previously I had all these parts running in a case with 2 7950 cards, one Sapphire and one XFX.  I put together an open-air rig and risers using the same hardware that was in the case (MB, Memory, proc), and added a pair of MSI 7950's, for a total of 4 cards.  I daisy chained a 500W to the 1000W power supply and have the 500W powering the MB, three 120mm fans to move air across the cards, a 1TB conventional HD, and 1 card.  The 1000W is running three cards.  I am not at my rig at the moment so I don't know which card is running off the 500W supply (this I admit might become important).  Fresh Win 7 install, 15.12 drivers, GPU-Z and HWMonitor, Teamviewer and nothing else.  After fighting with Windows and finally getting everything talking to each other I ran some spot tests for power draw and stability.  Everything looked good.  Started v11.0 miner and ran it for about an hour this morning and found that with my previous settings I used in v9.2 I was getting around 225 from the Sapphire, 220 to 230 from the MSI twins, and about 215 to 220 from the XFX.  I also discovered that one of the fans was vibrating about its shaft and generally being a pain in the ass.  I removed it and attempted to lube it but that wasn't its problem.  That being said, it still provided adequate cooling as indicated by GPU-Z telemetry.

About 15 minutes before I left to go to work I fired it all up and put it to work, walking out the door around 1pm.  According to the logs, temps across all the cards were steady around 62C to 65C (-tt set to 65) with fans ranging from 55% for the XFX to 40% (the baseline min) for the Sapphire.  About 25 minutes into the run the logs show the fans on the XFX ramping up to around 75%, but the temps were steady around 65C.  Seems the fan is starting to act up again.  Anyway, shortly after this I see the GPU temp fall rapidly and about 3 minutes later the watchdog found it unresponsive and commanded a restart. 

When it came back up it seemed to initialize fine but now it's running about 100 sols/s slower than the other three cards, at around 105 to 125 sols/s.  Looking at GPU-Z, the thermal and voltage readings are inline with a card at 100% duty cycle just like its brothers, but it's doing half the work.  Logs don't show anything extraordinarily funky except for one thing: when the watchdog ran a minute after the restart it showed:

"warning: solutions buf overflow, 1928276 > 24"

In the log prior to this was the speed check which showed the XFX running at 120 sols/s.

A few observations I hope might help.

I am not at the rig.  I am elsewhere monitoring it, so I apologize for not giving log snippets or screenshots.

All cards have stock BIOS.

All cards are normalized at 950/1350.  The XFX is based at 800/1250 but has been running at 950/1350 for months with zero issues.

All voltages are stock.

All cards are on risers (USB/powered).

The XFX card's riser is in the 16X slot and is driving the monitor.

The XFX is rock solid and happily hashing out 125 to 135 sols/s with no apparent failures. Telemetry suggests it's working as hard as the other cards.

I am not getting any rejected shares, neither prior to nor after the incident.

I can neither confirm nor deny that the XFX is the sole card connected to the 500W supply at the moment (aforementioned proximity to rig).

The 500W supply was not in the system when it was in the case running two cards. I removed it and installed a 1000W supply when I added the second card.

The 1000W supply is a single 12V rail supply.

The card hashes about 435 h/s using Claymore's Cryptonote 9.7 miner, while its brothers push out around 480 h/s. Oddly, the XFX is doing this using 37% GPU load, where the others are at 68%. O.o  Telemetry suggests this is true.

The card is deficient running v9.2 of the Zec miner.  It didn't have this problem with the same settings prior to transplant.  All cards are hashing around 180 sols/s except for the XFX (125 sols/s)

The tests show you are not the father.

So, whadda ya brains think? 

EDIT: Well, it looks like this card is lagging across the board, so it's certainly a hardware problem, and I'm suspicious that it's a power problem.  <s>To that end, how much power do these kind of cards pull from the motherboard?</s>

EDIT 2: Nevermind. 75W for PCIex16, 25W for PCIeX1.  I'm assuming that all cards are pulling 25 watts out of the board, thus 100W I didn't account for coming out of the 500W supply.  Hmmm...
