Topic: [UPDATE] RX480 (Ref) 31+Mh, Custom Rom - VDDC OFFSET + Custom timing (Read 231032 times)

... True. Actually, what You see in WattTool as memory voltage is MINIMAL GPU CORE VOLTAGE FOR THIS MEM FREQ. So if You set:
GPU 1120 @ 850mV
MEM 2050@1000 mV

You will get a GPU voltage of 1000mV.

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

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

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

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

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

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!

Hello,

I'm setting up my first rig and have (6) XFX RX480 8GB Black Edition cards. When I open my bios in Polaris Bios Editor, under timing I am not getting the same numbers as described in the examples. For example the first line is 26916491. Therefore I do not know which line to copy and past for the modification.

I tried applying one of the bios files supplied by the author, but when I did that Windows 10 would not recognize it. I had to boot into the command prompt and install the default bios to get it working again.

Can you help?

Thank you,

Brian

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

I must admit to use Ethos with 7 gpus mining eth, 480 Nitro+ 8GB.

My 1200W PSU uses 1.27kW(!!) at the wall while mining with 28.86hs

What is the best bios to get the power down - i already tried some, but no success ...
