can u tell waht pwoer consup u have per card ? and driver ?

[BartoszN1990]

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!

I used crimson 16.8.3, Claymore V8 before flashed and not change because all card can run normally. I Think, You try update to 16.12.2 and patched

I'm flashing the rom with the command line (cmd started as administrator):

atiflash -p 0 -f RX480Mod.rom

successfully.

After that the win10 => tool manager says, that the driver is hold on.

Now you have to sign the new rom with the tool: http[Suspicious link removed]

After that it works fine.

Thank you so much Eliovp for your suggestions and tipps :-)

I got a few pm's about custom rom not working with relive drivers.


Fix: Atikmdag Patcher

Tested on windows 7 with a few relive drivers, don't ask me which ones exactly but should work on all of them i guess, 16.12 for sure.

You can run it through an online antivirus thing if you don't trust me

I tested it under Win10 with the driver versions 16.12.2 and 17.2.1 too. It works fine.

After new driver installation you have to verify the rom again.

On my case: I cannot flash the 512 kb roms (RX480-32MhOTB, RX480-30MhOTB).

It said: "Can not flash a 0x0 length image into a 0x400000 length rom! Rom not erased. Error: 0FL01"

But the card is not bricked. It works fine with 28 Mh/s.

I've got a 30+Mh rom, 480 8G Samsung, around 60-70watt GPU-Z.

The ones i shared here years ago :p, are still good, but they're not custom timings..

Greetings!

Hi Sir, My system Hanged upon flashing 30+MH ROM for XFX RX480 8G samsung, is the rom posted last yr still available, thank you for the usual help in advance.

[BartoszN1990]

Well i have sph rx 480 nitro oc 8gb when i flash u rom ;/ show 4 gb ..

[Truthchanter]

any reason to upgrade driver to the newer drivers like 16.12.2+ from the older ones that you don't have to patch for working with modded bioses (like 16.3.2 i think, also 16.9.x)?

[citronick]

I'm running the 480LowEnergyOK rom on my Asus 480 8GB Reference cards and it seems to be running really hot. Anyone having this issue?
Fans are stuck at 33% according to Claymore and staying around 70*C with an outside rig where ambient temp is ~16*C.

All other cards follow fan curve in Afterburner.

Using MSI Afterburner for fan settings.

I've tried -tt 0 in Claymore with no results. Dedicated mining rig so no other fan monitoring software.

Windows 7. AMD 16.11.2.

I use the same rom mod.

No issues.

Have you tried -fanmin 55 - fanmax 99 ?

Ensure that you use latest Claymore miner version.

 using the RX480Mod.rom on 4 gpu's (28 mh/s). It works for the first time very well (24h). But after this time I have system freezes all few hours.

Does exists a mod-version without undervolting?

I'm using a ASRock Z270 with the following bios settings:

[Neo_Cool]

Does this roms work for an MSI ARMOR 480 4Gb?

[bughatti]

I just purchased a few of these cards, I read that they are reference cards, are they not because I have tried 3 different roms from this thread with no luck

Hello everyone

Very interesting this article on RX 480, but I have some questions that I would like to help me respond.

I have two Sapphire Nitro+ RX 480 4GB (Elpida) card  that I would like to update the ROM so that they can mine faster in ethereum. Which file do you recommend that I should download to update the ROM of my cards?

They are installed on a Win10 system with AMD Crimson 16.9.2, for me this is the best version to mine.

Thank you all for all the help you can give me! 

[Munchee]

Haha, i honestly was thinking, no way, that's impossible.
So i checked the rom i uploaded, of course, it's the wrong one  

Will upload the right one as soon as i get at my office.

Turning Idiotic mode off again...

Mate if you are still around you made my weekend with this!
Running 25 mh/s dual mining with Sapphire 480 rx nitro 4GB!

Stock 21.5

Previous OC at best was getting 23-24 and was very unstable. Sometimes less than 10 min,

You cranked my MH and my fan speed well down too.

Thanks buddy!
