Thanks,will try your rom when have little time available.

Problem is:

1.To reduce power-draw need to lower VDDC.
2.To reduce VDDC need to reduce VCCIO(the memory voltage in Wattman,but that is not the memory voltage,that is the memory controller voltage)
3.To reduce VCCIO the memory frequency will drop ,for 2170-2200 i found 5 cards need 0.92 .
4.0.92 VCCIO will limit the VDDC shown in Gpu-z to 0.9187-0.9250 resulting in 75-80 power draw reported in Gpu-z. ( at 1020 core )

This is all on stock rom which i run 1020 core / 2200 memory and resulting in 27 mh/s on all of my 5 cards . Would be curious the gains tighter timings make,can you test in this conditions too ?

Very happy with my results for RX480 however if additional 2-3 Mh/s can be gained in similar power consumption that would be absolutely awesome Cheesy

1. True
2. First time i hear that :p and it's VDDCI

You're right about the memory controller though.
3. Depends.. not every card is the same Wink

4. Interesting, going to test that out..

At this moment, over 1hr rock solid at 31Mh+

Stats on pool can be seen here: Link

Quick question,once custom rom flashed will the wattman app still work?

?

Sure does, check my included images..

Heliox... don't forget W8.1 too. If 120w/32MHs/60c is stable on non-WIN10... this is great news for me. But I dont mind converting some to Ubuntu rigs. Can you share the Linux environment you used for the stable Linux version? Thanks

Haha, just read your post over at Ethereum Forums which is exactly the same :tongue: Made me laugh

I didn't test on a unix system, got some friends over at ethereumos who did some testing.

But i'll try to keep eveyrone up to date!

I keep seeing @heliox write about windows 10 install, but has anyone actually gotten this installed on win 10? if so how exactly did you accomplish?

Boysie managed to get it to work as well

Thanks for posting your roms. I flashed 3 Powercolor 8gb ref cards (30MH rom). I haven't checked power usage but they are hashing close to before. One of the GPU's (my main) is having issues (display is pixelated and the picture is scattered), I'll relash that one in the morning.

Ubutnu 16.04 amdgpupro 16.30

22 - 24 MH/s

Edit: Crashed within 15 minutes - I flashed stock roms back until I can spend more time on this.

Speed is ranging from 21MH/s to 29MH/s.

Ok, here.

For the linux guys.

Just flash rom and run it, card won't consume more than 100w and will stay under 85degrees at all times.
No more jumping around between DPM states.

When running stock, speed on Ethereum will be around 30Mh (as you can see in my included image).

Core clock is set to go to 1191Mh and memory will go to 2200.

Rom: Here

Large image: Here

For the Windows guys, for now, same thing, only Windows 10 with signature check disabled and a modified atikmdag.sys file.

Had no chance to do a decent energy test, will do this later.

Greetings

As marvykkio said, thank you so much for share your modded bios.

I don't have a RX480, maybe I will buy one in few days, (moneyyyy Sad

) ... then I will try it and share here my results. No doubt about it.

World needs more people like you. Again, thank you very much for your comments and ideas, for share, and for your support!

Here's one for those who don't care about electricity.

Speed is around 31.5 out of the box, you can raise that memory to 2300Max but i wouldn't do that. Stick to 2275Max.

Core will go to 1285 and memory is at 2250.
Every limit raised, no worries, i did not go over specs, so there's basically no risk of frying your card

Rom: Here

Larger: Here

Ps. using these roms is at your own risk.
I'm not responsible for any damage done.

If you can't afford to brick your card, don't flash.
If you do not trust me, don't flash.
If you're happy with your card as it is out of the box, don't flash.

I don't need any donations or payments or whatever, a thank you is more than enough

I do this for fun and to help the community, also because i like screwing around.

I am however open for a serious cooperation with serious people or big farm owners

'who isn't :p'
Would they benefit from it? Of course, i never share my fastest roms Wink

Greetings!

You used beautiful words, and you've proven humble as a person, and not greedy like many people in this forum,
deserves all my respect.

if not use your rom because I'm not capable, I thank you for the help that you give to the community on the forum.

thank you so much.

So uhm, yeah, i managed to get my custom rom running on Windows 10 by bypassing that aweful signature check :p
(Kudo's to Gupsterg and Lordkag for that)
Decided to create a new thread because my other threads are becoming a serious mess..

Reason why using claymore's, couldn't directly get Genoil's to detect my card Roll Eyes

My apologies for that..

Results.

First run (no mod): 24Mh+ : Core clock 1275, Mem Clock 2000

Larger image: Here

Second run (modded): 28Mh : Same clocks, so: 1275, 2000

Larger image: Here

Next run (still modded): 30.5 - 31Mh : Lowered core to 1192 and raised memory to the (for now) max of 2250.

Larger image: Here

Then, for my final(for now) run: 31.5-32Mh : Raised core to 1220 and raised memory to 2275 Tongue

Larger image: Here

Will be doing more tests later, i'm sure i'll be able to go over 32Mh.
Great thing about this, when i ran the first testrun with stock clocks, card was at around 60 degrees and no abnormal fan speed.

Overall, awesome card

Power usage tests will follow later when i'm done tweaking my rom to the sweet spot

Greetings!

yeah i think its better to wait until a mod with lower memory and core voltage is reduced which should improve stability
keep us posted and thanks !

I flashed it using atiflash 2.74 on windows 7, plug it out and put it on ubuntu 14.04, with amdgpupro 16.30. Speed is very jumpy, from 21MH/s to 28MH/s. Sapphire RX 480 8gb reference card. Thanks for the bios, I`m sure it's still in early trial and I hope it still can be improved Cheesy
