Are you looking for a custom bios for a RX470 reference card or a non reference card ?

All non-ref I guess (Shappire, XFX, Powercolor, Asus and Gigabytes)

Eliovp,

Any chance to create this version => 480LowEnergyOK of your rom for the RX470 ?

Thanks

You can't create bios with offset using Polaris Bios Editor

You are right :-) So ... Create your bios with polaris bios editor , easy to use . If you are more experienced , use hex editor to change another settings in your bios file , this is the point when u can screw up ur bios if you don't know what u doing , so a lot of ppl need to skip this step :-) , then burn ur bios with atiflash . From this point the only thing you need to change after reboot is a offset voltage with wattool 0.92 . In wattool after you changed your offset voltage save ur settings as a profile . Next time after reboot just load ur saved profile in wattool :-)

little testing of my new reference rx470 4gb ))
first card in the miner - ref rx470 4 gb, second - crappy red dragon rx480 8gb samsung mem without cooling ((


if i restart the PC that Settings are gone, right? Or can i write them with Wattman perm?

You can " burn " those settings into each card bios with Atiflash , after created a custom rom with Polaris Bios Editor :-)

I have 2 x rig with 6 RX 480
No1 hashing 181.5-182 MH/s the whole system is pulling 870-890 Watts at the wall
No2 hashing 178-178.5 MH/s the whole system is pulling 870 watts at the wall

What are the system specs?

- Custom bios created by me for each card separately
- platinum rated psu's
- AsRock H97 Annyversary Edition / 8 GB ram
- 12 xfx non reference card , same model number , but each card need a custom bios tune :-)

Great work!
I assume you only get those results with Reference Cards by now? At least these results belong to them?

It should be possible to get these results with non-reference cards. You just need to know how to use polaris BIOS editor and know what settings are stable for your card(s).

And I'm certain it would be possible with a titanium efficient PSU.

No - it would not be

I can definitely see power draw from the wall at around 900w, and less.

You will not get 900W from wall hashing with 6 RX 480 with rate of 180MHs



YES , YOU WILL !!!

I am mining 180 mhash 850-900 watt stable for a week now...  Grin

Can you confirm it is from the wall for the whole system. It is not calculated or estimated from the GPUZ.

assuming that this wattTool is not part of Wattman?

Yes

Can this WattTool reduce -mV like AfterBurner?

Could you please upload WattTool somewhere and share the link? Overclockers asked to register for it
