It uses more power stock because of higher clocks, if u mod/undervolt, the power is almost the same as 400 series.

For dual mining i wouldn't even use a 1200w psu, let alone a 1000w one.
Dual mining with 580's will get you close to 1000w, way over the safe, 80% PSU usage.

Will it be feasible to fit 6 rx 580s 8gb on a 1000w gold psu with dual mining(dcr) ? I think the new rebrand uses more power than 400 series, or with tweaks is it comparable ?

Hey want to Build a Mining Rig with the RX570 / RX580 Cards.

Hello All.
I was able to get 6 x RX-500 series running on windows 10 x64. After two days the stupidest thing I tried worked  .
1. use DDU to clean the PC from any previous drivers.
2. Disable 4G decoding so you can log into windows (only  for Z170,H170, etc.)
3. Extract older driver for RX 400 series in Drive C: (I use 16.9.2 )
4. Extract driver for RX 500 series in Drive C: (I use 17.4.3)
5. Copy and replace all content from "C:\AMD\Non-WHQL-Win10-64Bit-Radeon-Software-Crimson-16.9.2-Sep21\Packages\Drivers\Display\WT6A_INF\B307117"  to "C:\AMD\WHQL-Win7-64Bit-Radeon-Software-Crimson-ReLive-17.4.3-Apr17\Packages\Drivers\Display\W76A_INF\B313057" (Basically you copy the old driver over the new)
6. Install the VGA cards manually from Device manager in Windows pointing path to the new driver 17.4.3 in this case.
7. Reboot and enable 4G Decoding in Bios
8. Enjoy if it works for you.

You can try with different driver versions if they work for you. I`m happy whit the 16.9.2 for the moment but any driver that works whit 6 and more RX 400 series GPUs should work  .

I know  that this solution sound stupid but it`s tested on 8 different rigs whit Asus Prime Z270-P and H270 Motherboards and works like a charm.
I`m pretty sure only handful of files need to be replaced but I don have the time to test more elegant solution.

Sorry for my English and grammar.

I got 4 of them, all using 1500 straps:
2x 1100 / 2050 / 875 mV - 29.2 MH dual (~680MH DCR using -dcri 22), 28.8 solo, temps around 70C, 50% fan
1x 1100 / 2000 / 875 mV - was stable on 2050 but too hot for my liking
1x 1100 / 1950 / 925 mV - low asic, hot and unstable on lower voltage

For some reason solo mining is slower, I lose about 0.5 MH per card.

A few GPU tests Sapphire 5xx. A few successes, but one problem.

I use:

Asus Z270F Strix - Without any problems, 7 GPUs work or MSI Z270-A Pro 6 GPU ready, I have tried, I currently operate about 10 Rigs without problem (RX 4xx)

Sapphire 580 8GB Nitro+ - Hynix - Strap 1750 - 1100/2200/-96mvGPU/50powertarget = 27,8MHs


Hynix on 570 is better then Hynix on 580. Hynix on 570 timing 7777 @ 1750 but 580 hynix 999 @ 1750 but i have to check this because the problem is two different time sets 1: 1750 and 2: 1750 each for another set of memories.


This is my tests, But I have a little problem. The signature for the modified bios driver is ok. But it does not work at the same time 570 with 580 on one motherboard.

If the 4x 570 works and re-sign the driver, the 580 runs but does not run 570.

Simply, it works either it or it. It does not work together.

Does anyone have any advice or idea?

Maybe a new Atipatcher?

Hello,

I have Sapphire Pulse RX580 8 GB and there's a problem. I have pasted 777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17 into 2:1750, 2:2000 and 2:2250. After the reboot it's hashing and showing:
http://imgur.com/a/7TW6D

Clocks set in Trixx 1200/2000.

I have already tried to copy 2:1750 straps but it didn;t work.

I can't handle it and it's getting me frustrated. I would be very grateful for any help.

EDIT:
After flashing the original bios it still makes the same error. Any ideas?

6x Sapphire RX570 Nitro+ 4GB in action ( 1200/2050@920mV core on all cards )
Just testing at the moment, still far from optimal.
The rig is doing about 940W dual mining and 750W@ 30Mh/s ETH each, which is still high, need to optimize further.
Also, tried one card on 2100Mhz memory, and its doing 30.5Mh/s ETH 

Anyone know, why i cant change voltage on memory? Claymore -mvdcc is not working, also no memory voltage in AB? What gives?

i have the Sapphire PULSE ITX Radeon RX 570 4GD5 (elpida)

but results are not great, @ 1244 / 1900

27.7mh on eth  with 1425 traps   so just little more than my rx470 (27.2mh)
on zec  higher clock than the rx470 but not faster
on Cryptonight the fastest traps are 1375 for 698mh, 678 for1425 traps, but a lot slower than the rx470 what does 760mh with 1375 traps

i m so disappointed
