Die Referenzkarten sind übrigens gerade wieder für 274 bei Amazon zu haben (sofort lieferbar - direkt von Amazon) :-)

Which one exactly? Which BIOS?

Getting ~58MH/s with my Sapphire RX480 Nitro+ 4GB, great job!

It seems I have big problems with my mod. Sapphire RX480 Nitro+ 4GB GPUs with Claymore 2.0. Did anyone have the same problem and did upgrading to 2.1 help?
Currently my rig is getting completely unstable with 2.0 in combination with those GPUs, but since I sometimes switch to ETH I would prefer not to reflash the GPUs everytime.

Die Werte beim Mining beziehen sich auf 1 Karte, der Verbrauch auf das gesamte Rig mit 4 Karten (also geteilt durch 4 und "Nebenkosten" von Board/CPU & Co abziehen um den Verbrauch der GPUs zu berechnen). GPU-Z Werte zählen nicht - entscheidend ist was aus der Dose kommt! ;-)

Nur zum Vergleich, ich habe 4GB Sapphire RX480 Nitro+ in meinem Rig (Werte pro Karte):
ETH Mining: ca. 27,7MH/s (Verbrauch kann ich gerade nicht prüfen, aber Rig mit 2x 4GB und 2x 8GB verbraucht 740W)
ZCash: ca. 47 sol/s (Verbrauch: 510W für komplettes Rig mit 4 Karten)

Beide Werte aber mit mod. BIOS.

Das war die Sapphire RX480 8GB Referenzkarte, jene die nun gerade mal nicht lieferbar ist - für die gibt es scheinbar gute ROMs.

Wie sieht es mit den 470ern aus? Welche Werte erreicht man da so (ETH/ZCash)?

Hatte auch überlegt, aber gerade letzte Woche waren sie bei Amazon für 279 noch "sofort lieferbar". Mit dem 30% GS-Deal liegt man dann unter 200.
Inzwischen sind die Kurse (der Coins) aber auch alle wieder "normalisiert" - das Gefühl zuschlagen zu müssen hat daher abgenommen

Das ist schon Richtig, die Goldgräberstimmung ist vorbei. Für diejenigen, die ohnehin ein GPU Rig hatten aber ein gutes Zubrot für ein paar Tage.
Ein Vorteil ist aber auch, dass es nun einen neuen, noch nicht ganz unattraktiven GPU Coin gibt. Aktuell verteilt sich dadurch die Rechenleistung besser, so dass der Ertrag bei ETH/ETC auf Grund dort gesunkener Diff steigt. Bleibt abzuwarten wo sich das in 1-2 Wochen einpendelt. ZCash hat aber unter dem Gesichtspunkt auch dem reinen ETH-Miner Vorteile gebracht

So 240-300h/s müssten das bei 6 Karten inzwischen sein...hätte sich gelohnt die ersten Tage (dort war die Leistung allerdings geringer).

I would also be interested and glad to test them

Thank you for the update!

One general question, maybe I am to blind to find it:
Is there an "easy" way to switch between Pools or do I always have to adjust the "Managed Miners" settings (set mining software + pool)?
It would be easier if one could change the pool via right-click on the miner (this is already possible) and the system automatically detects the required Mining Software (maybe assigned to the pool).
Currently I set up a pool in the first step and then set pool + software under the "Managed Miners" part. I think it might be better to assign mining software to pool settings, or am I wrong? (Actually I think I AM wrong since you have more experience with this)

Keep up the good work!

Edit:
Just wanted to mention that Mining Equihash on nicehash (BTC Payment) also works fine now!

You are right, this seemed to be the cause. But when I set device profile for that miner to "none" (otherwise I could only choose between sgminer/Claymore ETH Miner) the miner does not crash at startup, but is mining on a different pool than I set:eu1-zcash.flypool.org:333
I did not even define that pool (guess it is the default one from claymores config.txt), it does not use the selected pool for the miner.

How do I use Nicehash-Equihash with this version?

These are my parameters: equihash.eu.nicehash.com:3357
Login: BTC_ADDRESS
Pass: x
Coin: Unspecified Equihash

Advanced Tab -> Add: allpools 1

When starting a miner with these parameters it retruns the following lines:
UNKNOWN OPTION -etha
UNKNOWN OPTION -1
UNKNOWN OPTION -gser
UNKNOWN OPTION -1
...
ZEC: No pools specified. Specifiy at least one valid pool in "-epool" Parameter.

I have a Rig of 2 Sapphire RX480 4GB + 2x 8GB Version of them. All mining with claymore on stock BIOS.
4GB get around 35sol/s, 8GB around 40sol/s

Great work, thank you very much!
I had so much issues recently with other mining software in combination with my Sapphire RX480 Nitro+ (4/8GB) GPUs, but this one almost doubled my hashrate AND did not crash yet (since 3h now).

Claymore just released his ZCash Miner including an API:
https://bitcointalk.org/index.php?topic=1670733.0

Will you try to implement it?

This software is running stable with my Sapphire RX480 Nitro+ 4GB on stock BIOS with approx. 25-27sol/s.

Unfortunately I have several Rigs with those GPUS having a modded BIOS running at a hosting service. Although I can access the miner I am not able to reflash the GPUs via Teamviewer properly. Is there any chance to set them to "stock BIOS values" by settings?
With the mod. BIOS the mining software crashes very fast.

Looking at the topic I would say that does not care at all ;-)

I have a GPU Miner (with 5 modded Sapphire RX480 Nitro+ 4GB) hosted using Windows + Teamviewer to access it.
Unfortunately beside the fact that it does not run stable (GPUs stop hashing after short time, one after another) the whole system gets unaccessable after closing the Genoil-Miner Window.
The only chance I have to access the system again is to power off the whole miner (LAN outlet) and power it on again. Any idea why the systems crashes that bad after closing trying to close the window?
I would like to test around a bit and maybe get it more stable with running on lower intensity...
