Topic: [GUIDE][TUTORIAL][XMR,ETH]How To Mod Bios RX470/570/480/580 VEGA Mining 💰⛏ - page 33. (Read 220957 times)

I doubt the cards are any different. I have a few of those, and only one is acting like this. I do not know if the bios is messed up, or what...

Would you mind sharing your bios/settings with me?

In that case, what is your recommendation?

I am struggling with 470's nitro+ 4gb samsung (mining edition)

Just hit 300 000 memory errors on one card...

I can see that there are ubermix 3.2 straps available.

Are those better for rx470 samsung compared to the 3.1 ones?

after little of research I understand Vega 56 is most efficient than Vega 64 - but the Vega 64 is easier to get it up and running?

Amazing Guide ! Thank You for share.

I Need DGB Coin Guide . How to mine with amd gpu  ?

Thank You.

Yeah, it has been a while

A lot of things, mostly hiding from new crypto people 

Hi everyone,

I have problems to undervolt memory and core voltages.

Usually I mine with claymore at 0.85v (stable) with the commands -mvddc -cvddc and all is good, but I want to try nicehash.

So, I own rx 580 8gb;
 
I cannot undervolt with msi afterburner, memory voltage is locked for amd cards I read...I can only set core voltage but it's not enough to get me to 0.85v that I can reach with claymore.
I cannot undervolt with nicehash, it says failed to modify voltage.
I read editing voltages with polaris bios editor has no effect, I also tried to set 850 and it does not work.

How can I reach 0.85v or undervolting memory (and also core) in general, please?
Is the only option left to edit bios with hex editor? Am I missing something?

Thanks
Happy mining

Been a while Heliox what have you been upto?

There can be multiple reasons.  what are temperatures on the card.  Check for memory errors using HWInfo64.  Hashrate drops for 1 particular card or the drop is spread across multiple cards?

1 card might disconnected? Check for memory errors, maybe core voltages are too low.

Greetings guys i really need help from miner experts i put all my investment on this only pc but having issues like drop hashrate also sometimes restarts.

i own a SAPPHIRE RX 470 8GB MINING EDITION WITH HYNIX i used this tutorial to get it to 30hz http://1stminingrig.com/best-bios-rom-for-sapphire-rx-470-8gb-mining-edition-with-hynix-memory-30-mhs/

but i managed to get it 180-181 hashrate but after few mins or hours hashrate drops to 160 or lower is there anyone can tell me what should i do or how to fix this issue also sometimes it restarts randomly no idea why

here is my email if anyone is willing to help me out [email protected]

even with DAG fix the hashrates I get is 0.4-0.5 lower on same card same clocks on win 10.

Agree fully!

I have my cards set at 1150 core and 4 out of 8 can do 31+.
Sapphire Nitro+ 580 4g elpida

You can still easily achieve 31Mh+ with a core clock lower than that, heck, even with claymore and on linux...
Plus, you also quite often seem to forget to mention that you're most probably playing with a private kernel. Not that it matters that much...

Did 32+ on a 470 a while ago.

Can't see the clocks so i already know what the replies are going to be like.. (it was a 470 4G as well..)


But this one is 31+ with decent clocks as well.


Just saying.. It's not "that" hard..

Cheers!

Well like I say it's crashing after 5 minutes and I can't use the ROCm kernel anyway (or amdgpu-pro driver either because I'm using Debian now but apparently you don't need that).

When you say it's 0.5Mh/s below Windows do you mean with or without the dag fix?

You can use OhGodATool to monitor voltages and can modify values too (however doesn't seem to work properly with mydrivers)

I use rocm kernel and rocm-smi gives decent stats too like below
====================    ROCm System Management Interface    ====================
================================================================================
 GPU  DID    Temp     AvgPwr   SCLK     MCLK     Fan      Perf    OverDrive  ECC
  5   67df   36.0c    49.51W   1075Mhz  1950Mhz  67.84%   auto      0%       N/A

However overclocking is broken at the moment.  Using 17.40 drivers.

For me the performance is 0.4-0.5 Mh/s lower than windows.  However the gpus are a lot more stable than windows.

I can't even actually USE the ROCm kernel, because it uses the "radeon" driver for my 270, which in turn gives me an error about needing DRM V3.x.x instead of 2.50 (even though I am not trying to mine on the 270). I had to compile my own custom kernel with CONFIG_DRM_AMDGPU_SI=Y in the config and also amdgpu.si_support=1 radeon.si_support=0 in the kernel parameters. It was the only way to make it use the "amdgpu" driver for both cards.

Adding the kernel is easy though and there's no risk, because you can always just select the old kernel from the grub menu if it breaks. Just boot to your old kernel and uninstall the ROCm one.

Flashing the BIOS is no problem and I've already done that...but the other thing is that the -cclock/mclock/cvddc/mvddc params don't seem to work. I get the message "AMD ADL library not found" when it starts up and I don't know where to get those libraries or where to put them. I downloaded and compiled AMD "ADL_SDK_V10.2" (had to #include a couple standard libraries in the adl_structures.h file in order to do that) but it just gave me a useless "adlutils" binary, which also gives the same ADL library not found error when I try to use it.

Also apparently it crashes after a few minutes. Same BIOS works in windows for days, gets +1 Mh/s (24.3 in Win7 without the dag fix vs 23.4 in Linux), and I can even undervolt it further with afterburner. I have no idea what voltages or clocks it's actually using in Linux either because I have no way to monitor it. Only thing I can see is temperature and fan speed. I'm guessing the memory is not actually clocking above 2000 even though it's supposed to be 2050 which I set in BIOS. That would explain the lower hash rate. I added GRUB_CMDLINE_LINUX="amdgpu.vm_fragment_size=9" to /etc/default/grub as well but still not getting dagfix hashrates.

It's a fuckin' shit show trying to get it to even run, let alone run well.

Get your BIOS settings from Windows - then just flash to BIOS. Xubuntu is good once you've gotten this part out of the way...

well except I used to get 27mhs per 470/570 and now I get 22mhs cause I haven't updated to ROCm Kernal - cause I know when I try everything will fall apart... 

My GPU Mining Time is a lot of Time in the past.
what for a GPU is at the moment state of the art for GPU Mining?

They come from oc.net PBE thread. Look under 480/580 Performance Timings spoiler in the OP
