i can get high 23 -24 m/h. How do i get more without touching the bios and how do i mod the bios correctly? I have already tried once on a card and after modding it nicehash no longer seen the card. i even loaded the default bios back and it still could not see the card.
also after reading a bit i installed some blockchain drivers, now i am getting 19-21 m/h and i had the normal amd drivers installed getting 24.
what is the correct way i should go. i have more gpu’s to install soon
I originally modded the bios on all my AMD cards, eventually switched to SMOS-SimpleMining, and have been pleased with their consistent updates, drivers etc. if you find you are having trouble or aren’t comfortable flashing bios etc, you may want to check them out. I’ve heard people say they like HiveOS as well but I have no experience there. You do pay $2 per month, per rig so maybe not worth it unless you have several GPUs, but I’ve found the cost pays for itself with rig stability etc. Very happy with the Vega rig there, was a bit of a nightmare trying to tune those in, but SMOS has a nice set-up.
as of now i am using wifi on my current test rig and the furture one. I don;t have enough ports to run wires. simplemining and hiveos i don’t think support wifi
You probably need to run the AMD Pixel Clock Patcher if it wouldn’t see the card after messing with the bios. Also, unless your electric is free, maximum profitability may not be going for the highest M/H. The AMD RX series tends to run with a lot higher voltage than they really need.
I made a thread on this Undervolting and Overclocking - though there wasn’t a ton of replies. With the base AMD controls, you should be able to adjust a lot of the tuning and voltage usage, without having to go to the BIOS level. Likely dropping your voltage at max load is going to save you a lot on electric without significantly impacting your hash rate.
Also, did you switch the cards from graphics to compute mode already? That’s supposed to help a bit with mining (NiceHash probably recommended it as well).
also when i tried to bios mod my card the first time, i got my information from the video of vosk you posted. When i did the bios editor on the right it had a drop down menu with two bios’s. One said some numbers and saud “unknown” next to it and the other one gave some numbers with " mircon" next to it.
My concern is gpuz said i had samsung memory, but the editor didn’t say that. Also i didn’t know which bios to pick from that drop down menu, so this is how i screwed up.
also should i use the tools he shows in the video or use the newer ones out?
It is possible for a card to have mixed memory. There’s another video that goes into this, which I can’t find at the moment. But, yes, the newer versions of these apps would typically be better to use as they are more likely to correctly recognize a card.
yes there is a switch, with the normal amd drivers installed i get the same rate on both. I didn’t try the blockchain drivers on both. From what i can see one side is performance mode and one is quiet mode. But i also heard one side for was gaming and the other mining
meaty the problem is i have already tried to mod one of these cards and it messed up. As i said above when i open the editor in the vram spot there is two different sets of numbers. One says unknown after the first set and the second one says micron.
I have no idea which one too pick and i really don’t understand why it does not say samsung when gpuz says i have samsung memory
on the card that you modded it should have only changed one bios unless you moved the switch and then flashed the bios again. you should be able to move the switch and still have one of your original bios still in there
when i first did the mod i didn’t know about the duel bios. after i modded it i loaded nicehash up and the program didn’t see the card, gave me a error. So i tried to load the main bios back and it still didn’t work. i tried loading the main saved bios a few times and nothing. so i sent it back
when i tried to mod it i used the unknown one because that was the one that comes up first, and still don’t understand why the second one says micron when i have samsung memory in it
now i know that it has duel bios i am not worried to try it again. maybe i made an error when saving something
really i don’t know. I repeated what i am supposed to do and it worked. But i have been running nicehash for awhile since then and it keeps giving errors and it stops mining and tells me i have to restart my miner.
