Yes, but only with Afterburner version beta 4.4.0.16, i found it on the link below, i tried to undervolt it was ok for consumption, but jumping issue always there.

Jesus there are some greedy people in this thread.

Trying to sell modded BIOS' for 0.1BTC or 0.85 ETH - fuck the fuck off!

It takes 5 minutes to watch a youtube video (or search a forum, this thread is a good start) and mod & flash these BIOS' yourself.
Then a bit of effort to test and tweak your cards, which if you are serious about this is a joy not a burden.

As if miners aren't taking the piss out of each other enough already with the resale prices of cards (saw somebody on Ebay asking £500 for a 4GB RX470 Nitro+ just last week) now they are trying to cash in on newbs for something that they could do themselves with 5 minutes of research.

Where has the team spirit gone?

If I'd be you, I'd surely be pissed about it, as AMD clearly states what is considered RX560:

http://www.amd.com/en/products/graphics/radeon-rx-560

so there should be no cards like yours

No, 45W version is the one without external PCI-E connector, so
its restricted to draw max 75W (from board) while 90W one can use
max 150W (75W from motherboard and 75W from PCI-E 6-pin connector)


Radeon RX 560       Radeon RX 460    

Shaders     1024    vs    896    
Compute Units    16    vs    14    
TMUs        64    vs    56

But in previous post you said

"I bought 4 -NEW- Sapphire RX 460 unboxed from a sealed box... Sad  "


Whatever...460s have 14 CUs and 560s have 16 CUs...draw your conclusions form that fact

Strange then, that someone modified them at factory...still good rate, 3 out of 4
 460s transformed into 560s is OK in my book

But why did you say 560s in your original post?

Sounds like you bought modded RX460s, but mod didn't work well on one of cards

I think its answered few hundred times on this board alone...you have to patch your video drivers
to recognize your card with modified BIOS

I modded the bios successfully and increased the mining speed to ~14.xxx mh/s with the following settings:

bios mod:

1750 timings -> 1875, 2000
max memory clock 2000 -> 2200

amd radeon settings:

gpu clock -> 1125 (underclock)
memory clock -> 2000
fan -> 100%

ASIC is 65% and 75% so they run 60° and 53°. Memory is Micron 4GB.
Could push the memory clock further now but I'm satisfied and let them work for 48h.

I think they could do 15.xxx mh/s but with much more power draw and heat dissipation.

And disable crossfire in amd tool, enabled by default!
