Want to mod MSI RX 470 Armor 8GB OC

[jackbox]

What would be the best way to mod this card for better hashing rates? I see people taking about modding the bios and moving memory straps 1500 to all higher memory frequencies. Is there anything else to be done? When I run MSI Afterburner the voltage is fixed (slider disabled) and everything I have tried to enable it has failed (config file change, etc.). Here is the info from my bios. The card has Samsung memory.

It's a Samsung card you can easily get 29-30MH/s+ with a simple vbios, PM me if you want to buy a modded rom.

[insider00]

send  ur rom, i will edit it for u, and will teach u how to use wattool ( For free )

[jackbox]

Thanks. PM sent.

Actually, which memory strap are you using as best for samsung 8GB?
Do You care about memory errors and clock down until the errors are about zero?

[sxafir]

Try using benchmark to overclock this card but if you do that artifacts may showing.This is no worth time.

Hi,
I'm beginner in GPU.
I would just like to improve Ethereum Mining for my MSI RX470 4GB. (22.5MH/s on claymore)
I've seem many comments and started to prepare all.

My rig is linux (Ubuntu 16.04 with v17 AMD Pro drivers), and I have found ATIFlash for linux and saved by current bios (see below).
On my laptop I have installed Polarisseditor.

Is it enough to just use polariseditor to adjust few parameters ?it seems RAM timing are most important?
What are the "memory strap"
is it in VRAM the "timing", and how to change it ? What does the timing Hex values mean?

Is it needed to really change the bios?

I've made a pane gathering all the options available in PolarisEditor,
what should be changed, for a noticeable improvement?

Is there a safe method to tune the settings ?

I've gathered the settings in Polaris editor.
The straps seems to be the long hexadecimal values for VRAM, but I have no idea what it mean and what to change..

I think I missed just a few keys, but hard to connect the many comments, hint and tricks ev

If it works I think I could write the howto that could help people like me next time

Hi!

I have a MSI RX 470 Armor 4g with samsung memory. Can someone help me. I'll tip some ether.
Here is my original bios:

Thanks a lot!

I have advanced as beginner.
Keep a backup of your bios.

PolarisBiosEditor allows to tune few key parameters.
https://github.com/caa82437/PolarisBiosEditor (1.4 not compatible with elpida)
https://github.com/tpruvot/PolarisBiosEditor/releases/tag/1.4.1 (less tested but works with elpida)



For ETH mining usually you have to

• copy the long hexadecimal stride VRAM Timing ate 1500 or 1650 or 1750 to all stide below. those stride are complex code to determine the timing of VRAM. copying 1500 timing into 1650 will make the ram faster at 1650MHz (but less stable). copying 1500MHz timing to 1500+ make me move from 22.5 to 23.7
• increase the VRAM speed where it is associated with a voltage (typ you have 300MHz 1000mV and 1650MHZ/1000mV, just change 1700/1000mV or more )
• at the same time lower the GPU max frequency nearly half at 1100MHz, 1200,1250
• think about slightly undervolting or overvolting the VRAM or the GPU... sometime better have them evolve same way, sometime independently... this is a point where I need help

all is better explained here
http://cryptoyeti.com/rx470-bios-mod/
read also the spreadsheet there
https://drive.google.com/drive/folders/0B6vofcgy8sqJbEZHMzkwQ3gzd00
and watch the bios.
see too
http://www.overclock.net/t/1604567/polaris-bios-editing-rx480-rx470-rx460


never use someone else bios, but open then with PolarisBiosEditor.exe, and see what they changed.
go slowly, and let your mine work for a full day stable.
I was happy with a change after 1 hour of test , but when I get to bed my miner fall into "incorrect shares"...
now I go more modestly with :
GPU at 1100MHz, strides 1500 copoed to  1500MHz+ VRAM ar 1750MHz

if you brick your video card, often this mean you cannot login with video card.
I work on Unbuntu, and when my card was bricked i could only login by SSH, and I have to reflash the stockrom with linux atiflash.
It seems there is a DOS version of atiflash which work befoere windows...
on windows however you have many tools like GPU-Z and a recent tools by AMD to overclock without flashing (forgot the name).
it seems there is also a problem with windows and mod bios, because my ubuntu driver moan about bad signature of rom... and works anyway.

for those interested I've made a script to use atiflash, backup previous rom, install ne, check, backup new...
I've integrated it in my own "minerwatchdog"... when there is too many "incorrect share" in the miner log, I flash the stock prom and reboot... Frustrating to lose a night of mining because card was overclocked too much.

What would be the best way to mod this card for better hashing rates? I see people taking about modding the bios and moving memory straps 1500 to all higher memory frequencies. Is there anything else to be done? When I run MSI Afterburner the voltage is fixed (slider disabled) and everything I have tried to enable it has failed (config file change, etc.).

I sent you a download link to the modded rom which works great on my card.

Thanks for sharing but now im not sure what I have to do
I got drivers problems.
Must I use linux to mining with it???

Hi again,
after research a little bit Ive installed another driver version, and After burner detect it as (Crimson 16.6),
Now i can mine with better Hashrate but ive got 25.4 maximum stable. Have someone got better Hashrate with Armor card??
Are you normally setting by watttool?? or using Afterburnner???

Million Thanks

I am using patched Relive 16.2.1 and my hashrate in dual mining mode averages about 26.5 MH/s. Cryptomined on Youtube has a video on how to install and patch it with links to all the files.

What hash rates are you getting on the 2nd coin? What is your dcri set to? I have 5 470 8gb that I need to mod and turn them up. Just wondering what others are getting for dual mining stats. What memory speeds are you running them at?

I am dual mining PASC. It has a lower hashrate than DCR gets but make more money mining it. Average hash rate about 215 MH/s and the -dcri setting is 8. That is where I got the best ETH hashrate with PASC rate. I can get PASC much higher with higher -dcri but then ETH goes way down.
