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

[Walrusbonzo]

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

[crazyearner]

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.

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?

[thefire2009]

ok, problem solved

i just wanted to ask, is there a reason the final 33Mh/s rom from Heliox was not released and the other posted roms in the 1st page are down? 

awesome job btw!

[shadabahmed]

is there any modded bios for 470 oc 4 gb?

[merc84]

Anyone know why the gpu voltages are not in actual mV? Is it safe to just enter a value in mV? This is Mis rx 480 4gb btw, thanks!

So you have card bios with timings same from 800 all the way up AND IT IS WORKING?
Yes, you can put voltages...
