[UPDATE] RX480 (Ref) 31+Mh, Custom Rom - VDDC OFFSET + Custom timing

[Walrusbonzo]

Yes. What GPU/Memory clocks do you want? I found my cards don't like more than 2150 on the memory and therefore core clock of 1125 is about the max needed. Gives me 29.7mh/s per card.

I can set GPU voltage to 1v, but not yet tried to edit the BIOS voltage ofset, so if you want lower GPU voltage you'll need to do it in software.

I can post later let me know what you want.

29-30Mhs is fine. I can adjust voltage in AB later.

1125/2080 settings look like those from this website:https://forum.ethereum.org/discussion/9650/sapphire-rx-480-nitro-oc-8gb-11260-01-20g-modded-bios-29-mh-downvolt

If so - this does not work on my card

The original BIOS is: 113-2E3470U.S52

Thank you!

I'll see what I can do for you this evening.

Cheers

EDIT: I'm under 810w now and still maintaining 178.6mh/s. Been stable all weekend

That is very efficient. It is more efficient than the AMD R9 Nano. Your card is less than 50% of the Nano.

What kind of hashrate is typical for a nano/fury/fury x?

I've got a couple of Powercolor Devil RX480 8GB coming tomorrow. Anyone else using these for mining?

Edit:
Put the new Powercolor Devil RX480s in my main PC so moved the Sapphire cards into one rig of 6.

6 x Sapphire Nitro+ RX480, mining at 180mh/s, drawing 845w from the wall with a EVGA 1300w G2. I suspect if I was to use my EVGA 1600W T2 I could get it down to 820w, maybe even less.

All cards set to 1130/2175 with core voltage at 0.9v.

I knew it could be done!

Happy to post video proof if anyone wants?  

Nice work on the nitro indeed. You modding any of the MSI range or you already tweekd round with them?

Thanks Not played with any of the MSI cards and no intention to currently.

These Powercolor cards are good though, while the Sapphire ones seem to top out between 2150~2175 on the memory, quite a lot of memory errors at 2175. These Powercolor cards will go to 2200+ on the memory and no errors

With regards to your powercool cards worth grabbing vs sapphire if same price then as found shop that appears to be doing the sapphire and also powercool at same price and seeing you topping 2200+ on cool card am guessing getting a nice extra hash too. Whats th power you drawing from it?

Did you get the refferance design or did you get the red devil version? Thanks in advance.

I don't know the power draw from the wall for these cards exactly, but it can't be much different to the Sapphire cards. And yes they're the three fan Devil cards.

What hash you getting from them devil cards compared to sapphire ?

[Walrusbonzo]

The Powercolor cards give 30mh/s at 1125/2200.

The Sapphire cards give 29.7mh/s at 1125/2150.

They give identical performance at the same clock speeds.

Whats the error rate at am geussing no errors on the power as explaind before. Think somone was asking to use some tool to posts its error results after x time cant find the post to it. But still looking good tho guessing ig hitting 30MH on the cards then am guessing the powercolor seems to be more of a solid card then compared with sapphire

it is possible to get some link, for bios for, sapphire nitro+ oc 4Gb for 30-+mhs ?
Please.

Could I have some help pleaseeee...

Rig overview:
Win 10 Pro
AMD 16.10.2
XFX RX 480 8GB

Issue:
When running older AMD drivers, I am able to load custom ROMs (using the driver sig method).
After updating to 16.10.2 the drivers are showing a warning in Device Manager... therefore Claymore will not mine.

Troubleshooting carried out:
Reset WattMan
Flashed back to Stock ROM
Uninstalled GPUs in Device Manager
Ran AMD Removal Tool
Installed 16.10.2 < GPUs working on Stock ROM at this point.
Flash custom BIOS (Boysie Low Pwr 29Mhs) < Was working on older driver without issues

Am I missing something, why cant the custom ROM load with the newest driver?

You just need to search this thread. There are quite a few good mod bios for several GPU brands.

elpida?

If you find the right memory strap for your elpida, it is possible to get that GPU to have 30+ MH/s rate.

[thefire2009]

please, any settings for polaris bios editor, for sapphire nitro+ oc 4gb??

[thefire2009]

why... if change anything in polaris bios and update bios on my sapphire 4gb, it not working, no picture nothing?
even if change only 1mhz in the memmory.
even if manualy put back on stock settings, not working, i must flash with stock (backup) file/bios...

why???


Update
i open original (backup file) in polaris editor 1.4
just open and save... flash saved bios... not working

like, polaris bios "destroj" the file.

what is going on?

[risinqsun]

great job

[thefire2009]

i have rx480 sapphire nitro+ oc 4gb
and the same card with 8gb

bios of 4gb... in the polaris editor, i have 3 options in VRAM menu
bios of 8gb card, has only 1


?

[thefire2009]

ok, problem solved

now PLEASE some one... link to a rom for 27-28mhs+ for sapphire nitro+ OC 4GB

Thank you
