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

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

Give me a few more days and i'll probably be able to do 30+Mh on my 480 at 100watt if not less.
And that for almost half the price ;-)

Haven't had time to read all the replies.. sorry for that.

For the linux guys.

Rom is here: Here


For Windows 10 users, you can do this:

i) Press Windows Key + X to open Power User Menu. Select Command Prompt (Admin) from the menu.
ii) Once the Command Prompt open, enter bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS and press Enter. Then enter bcdedit.exe -set TESTSIGNING ON and press Enter.
iii) Close Command Prompt and restart your PC.

If this fails for some reason, you can reboot with Signature checks disabled by rebooting into advanced options (Hold left shift key while hitting reboot button) and hit F7.

You need to copy the modified atikmdag.sys file into your drivers folder as well (C:/Windows/System32/Drivers)

File can be found here: Here

Rom has modified timings and higher limits. (Memory 2275, higher tdp limit...)

I'll do an energy friendly rom later this week.

For the Windows 7 users, i'll look into that this week.

Greetings

No, i haven't.

I'll do one in the coming week.

Here.

Did a quick test run, stock clocks: Core 1220, mem 2000. Eth speed: close to 28Mh, Sia: around 400+Mh.

Have never needed to do that, but yup, if you have onboard vga, or another GPU, you can still easily flash your badly flashed or bricked card. (If it gets detected though :p)

Exactly..

I'm still figuring out a way to make it easy for everyone to bypass signature check.

For the *nix users this isn't a problem.

I'll let it run for at least 12hrs before i even think about releasing something.

So far 4hrs, stable as a rock. Temps around 70 degrees, fan at 85% :-)

Greetings

Why wouldn't it be true? 



Perhaps.. time will tell 

VDDC Offset + Basic Custom timing
------------------
Here's a nice update for those who have Reference cards.
In the package included, i've put 4 roms with VDDC offset.

1. -50mV
2. -69mV
3. -81mV
4. -100mV

You can of course adjust these however you want, if you want to have an even tighter undervolt you can search the rom for this --> "8D 00 F8(-50)00" and replace the F8 part with EE(-112) for example.

These roms also have a custom timing included. It's a basic one but it will give you a very high increase for XMR.

Greetings and have fun!

Relive 16.12 fix
------------------
Atikmdag Patcher


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   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  



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!

There you said it all.. 1180 core!

Dunno if you noticed but my rom does around 15 at core 1080 (so -100 on your core).. 

Nah, i uploaded a modified one. Trust me.

Bios is modified in such a way that you need to set specific clocks or it won't make any difference.
I can however do so that the speed changes on any clock you set.

Read a few posts up.

I'll quote it.


So just set your core clock to 950 and your memory clock to 1600
To compare, set those clocks with the stock rom, run your miner. Flash your card and do it over. You'll see a significant increase.



To everyone else.

The positive thing (in my case) about sharing roms now and then, for free, is that i can do mods whenever i feel like

You can send me pm's, i don't mind, i'll reply when i find some time, but it's impossible for me to modify each and every one of your roms.
That doesn't mean that i don't want to though Just need some patience.

Or... you could put one up for sale, as soon as i see that, i'll put one up for free 


Greetings!

 


Probably somewhere yeah :p

Will look into it tomorrow.

Force it

atiflash -f -p 0 romname.rom

If you don't have a backup bios, and not absolutely sure you're willing to take the risk.
Don't do it.

Happy you guys like it

Yeah, used VBE to save my rom. Wouldn't work without ;-)

Here:

Tested on a 380Nitro

Completely free. No bullshit clocks of 1750.

just run at 1625, maybe max 1650 and core at 950.


Ps. Flashing your card will void your warranty. So don't do it if you can't afford to brick your card. (not that it won't, but still..)

Atombiosreader to get the exact location for the offsets, HxD and a calculator. 

Oh, and notepad as well.

You kidding right?

Memory 1750.. you do realize that 95% of the 380's aren't able to handle that clock for longer than 12hrs under full load?

+ asking people for money for copying some timings from one strap to another.. seriously...
Edit: i'm almost sure that didn't even happen..

Just because i hate these kind of posts, i'll do one as well and share it for free.

greetings

Yeah i know, signature check :/
