As per request. -- Sapphire-RX470-8GB-MINING_BIOS

** WARNING **
UNTESTED BIOS

^^^ Powercolor rx560-4gb mining OEM, nothing but problems... they're dirt cheap though. They should be almost identical to the red dragon.

2250 on RX560 hynix? What kind of card is that, Gigabyte can barely reach 2000.
Although, someone gave me info that Powercolor uses R2C on Red Dragon RX560s, unlike Gigabytes R0C

The only cards I'm currently running at 2250 are some powercolor rx560's with hynix. Only 4 out of 7 cards will run at 2250 and this memory is designed to run that fast. Running micron rx470 cards at 2250 is gong to be even more scetchy as they come at 1750 stock.

Claymore just released a new xmr linux miner yesterday so I'll try setting my samsung and micron cards with his new miner first, if all goes well I'll flash the cards to that speed and post the bios'. But really, 2000 is the fastest most cheap cards will run stable at.

Did you manage to get Micron to 2250 stable? My highest is 2230 on RX560, any higher than that starts to get errors in hwinfo

I'll check it out in a few hours and see what can be done, I should be able to get you to 29.5 ETH/810 XMR. 900 xmr might be possible but without the card in hand to test I'm not going to force the memory to 2250.

My RX560 micron experience is very good, bet that rx470 can do good too

Anyone got a good BIOS mod for a Sapphire RX 470 8GB? Memory is micron.

I'm able to edit the timing straps using the 1.4.1 bios editor but simply copying the 1500 straps only gives me a max stable hash rate of 25. MH (dual mining ETH).
Any help on this is highly be appreciated.

^^^ Post your BIOS and I'll mod it, you've got a card that doesn't exist as far as I can tell...

This Aorus rx580 8gb card is hopeless.

I UNINSTALLED MSI afterburner beta 19.
I then boot in safe mode and run DDU to remove AMD drivers and prepare for card installation.
To make sure it's not a power issue, I removed 2x1060 cards from the rig.
I installed Gigabyte Aorus rx580 8GB(hynix H5GC8H24MJ) and booted into win10.
I installed the blockchain driver(driver only, other options unchecked).
Next I installed the atikmdag patcher.
Next I rebooted and then installed MSI afterburner beta 19.

I checked MSI afterburner beta 19 and found that I can't modify core voltages.
I tried running claymore10 with: -mode 1 -platform 1 -benchmark 145 -tt -80 -tstop -79 -cclock 1100 -cvddc 950
result: 24Mh/s 100W(gpuz power draw) and temps rapidly climbing to 79C(terminating claymore10) even with fans at 80% and 950mV was IGNORED

I tried running claymore10 with: -mode 1 -platform 1 -benchmark 145 -tt -80 -tstop -79 -cclock 1000 -cvddc 950
result: 24Mh/s 90W(gpuz power draw) and temps rapidly climbing to 79C(terminating claymore10) even with fans at 80% and 950mV was also IGNORED

I tried running claymore10 with: -mode 1 -platform 1 -benchmark 145 -tt -80 -tstop -79 -cclock 900 -cvddc 950
result: 22Mh/s 85W(gpuz power draw) and temps rapidly climbing 79C(terminating claymore10) even with fans at 80% and 950mV was also IGNORED

I installed sapphire trixx to try to undervolt.

undervolt by: -156mV
I tried running claymore10 with: -mode 1 -platform 1 -benchmark 145 -tt -80 -tstop -79 -cclock 900
result: 22Mh/s 80W(gpuz power draw) and temps stable at 69C with fans at 80% and vcore:0.89mV

running higher core clock regardless of undervolt results in temps climbing to 79C(terminating claymore10)
anything at or above 85W (gpuz power draw) results in temps climbing to 79C(terminating claymore10)

this is all done with stock bios. help???!!!

@notbatman
thats aorus xtr.

I have the regular one

what command did you use to view the information you posted above?

VendorID 0x1002
DeviceID 0x67DF
VRAM: H5GC8H24MJ (HYNIX_2)

Hope you can help me.

Yes.

@notbatman
am quite sure its hynix based on latest gpuz and polaris bios editor

do you happen to have the stock bios you are referring to?

^^^ The Gigabyte Aorus RX580-8GB has Samsung memory according to the stock BIOS... The 4GB version has the slower SK-Hynix memory.

Hi guys! I hope you can help me.

I recently obtained my first AMD card which is an Aorus RX 580 8GB Hynix(shown in gpuz).
It is currently installed in a rig with 2x1070 and 6x1060 as the 9th card.

OS:Win10 pro
Driver:amd blockchain driver(aug 23)
Bios: stock(1365core,2000mem)
Miner: claymore v10.0
EthDcrMiner64.exe  -mode 1 -platform 1 -epool eth-sg.dwarfpool.com:8008 -ewal 0xAAAAAAA -epsw x

at stock bios and stock clocks and voltages:
ethash: 22Mh/s @ 120W with temps rapidly reaching 80C+ even with fans at 100%(3400rpm)

I already did the most basic bios mod of copying 1750 -> 2000 timing straps
Bios Editor: Polaris Bios Editor v1.6.2(https://github.com/jaschaknack/PolarisBiosEditor)
ethash: 25Mh/s @ 120W with temps rapidly reaching 80C+ even with fans at 100%(3400rpm)

performance: poor. temps: too high. power: too much.
Should I just give this card away?

can someone share good roms for this card?
What hash rates are you getting at what power consumption and temps?
Are you guys using the blockchain driver? Should I shift back to regular drivers?
Are you able to unlock core voltage controls in MSI afterburner? Its currently grayed out.

Yes I know it. But I think that it can better.

The 777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17 is the same strap bundled with PBE v1.6.2 from jaschaknack. I have the same card and it has dual timing straps. The 1: straps are K4G80325FB (SAMSUNG) timings and the 2: straps are H5GQ8H24MJ (HYNIX_2) timings. Using the PBE 'one click timing patch' with 1150 MHz core clock and 2100 MHz memory clock I get 29.5-30 MH/s.

https://github.com/jaschaknack/PolarisBiosEditor

Are you sure? Looks like a total mess when I enter that strap into editor

I have MSI RX 580 8G with hynix MJR memory.
Best stripe that gives me about 29M eth speed is:
777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17

Any tips to improve this stripe? Or other stripe for hynix MJR 8Gb?

Timings from stock vbios:
1625 - 999000000000000022449D00105A7B4480551312B88C250B004C0401750514204A8900A00200712 417112E34B22A3916
1750 - 999000000000000022559D0031627C4990551313BC0D060C004C04017D0714204A8900A00200712 419123138C02D3D17
2000 - BBB000000000000022889D0073EE8D53A055151743CFB60D004E24010E0A14204A8900A00300712 41C143840DB324418
2250 - BBB000000000000033BB9D00D6FEAF5EC05517174BD1770F005264011E0E14204A8900A00300712 420173F48F7384C1A

This any combinations of stock timings (1625 to 1750+, 1750 to 2000+ and 2000 to 2250) gives maximum 25-26М eth speed.

Those are not revisions, but speed ratings
