Hi all,
can anyone suggest me (best to do miner) what is the best overclock settings for RX 580 8GB mining.i am using nisehash.

My best is 1100 core and 2050 memclock.
Bios mode or -strap 1 in phoenix and You`ll get 29.9-30.5Mhash.
It`s power setting`s. Somme gpu`s can handle it at 750mv, somme at 850(samsung hynix memory)

My own best settings for rx580 is cclock @ 1130 and clock 2200, the mvddc should be right at 850 and the cvddc should be at 850, this is overclocking and undervolting your gpu and it should output 30mh/s, though Hynix is different from Samsung memory, you gotta find that perfect spot

My sapphire Nitro+ rx580 8gb running on 32,6 mhs with 1200/2200 890mv ~100w from wall.

how people can go so down. my some cards even dont down after 940mv. core voltage doing 880mv but it doesnt effect consumption but memory voltage effects alot. as soon as i give 920mv on memory then after couple hours crash. and also with 940mv i cant go up 2070mhz it will crash, how people cards stays stable on 2200mhz?
Ofcourse miner showing very less 66w-78w.

cclock 1120
clock 2100
mvddc 900-950
There are no perfect settings for all graphics cards
You will have to choose those settings at which your farm works stably, this can only be achieved empirically.

You have to find a perfect spot for your own gpu because there is no perfect settings for a gpu, they are different even if they are from same brands, I just find downclocking more effective than overclocking, that's after spending years with few mining rigs

RX 580 Sapphire Nitro+  MOD BIOS
win10 1703
Driver: Adrenalin 2019.5.2
Miner: Phoenix 5.3b
cclock: 1250
mclock: 2250
cvddc: 850
mvddc: 880
Fan: 30%
temp 55
card power 84w


And ETH  33,7MH

I have both RX 580 MSI Armor X OC and RX 580 Gigabyte AORUS.

My sweat spot is with TeamRedMiner 0.8.0
core 1150@825mV
mem 2150@800mV
62-64W reported in HiveOS (probably something like 110W at wall)

31.15 MH/s per GPU

I'm glad with it, because of the low power and low temp for a really nice Hashrate

thank you kind stranger i have the same card that reaches 33,4 just with cclock = 1225, cant go higher unfortunately

now i am trying to reach 30MH/s with my rx 480

Because mem voltage and core voltage running the same voltage. If you set core 880 and mem 920, the card runs with 920 on core and memory. Different voltages have no effect, another bad point on many linux OS. You set a voltage but the cards don´t work on this voltages and this is not shown and no error or something like this.

It depends on the memory type that's inside your GPU, some rx580 can't do memory OC over 2000mhz without crashing, for example on my rx580 with micron memory I can do 2160mhz anything over this will bring instability and system reboot

Here is what works best for my rx580s with hynix memory and outputting 32MH per second, pretty stable no reboot after several days of mining

Memory clock: 2150 / 750mv
Core clock: 1070 / 800mv
Fan speed: 71%
Power limit: +0

I'm using nanominer (since claymore is wonked) and I can't find anything on -strap and -rxboost for it.

Which miner are you using?

Thanks in advance to anyone that can help me to get back to 31mh (sigh)

No strap and/or rxboost settings?

Thanks

/\ THIS. I have used several different miners and OSes and there is variance there, too. You have to set each card individually and test it out for various periods to find what works best. Also keeping in mind longevity; if you want to make a quick turnaround/buck than go full force. I keep mine at about 90% what they COULD do, but I've had zero downtime on 6 580s for close to 4 years now...

Rxboost for RX 570 and 580 isn't available in all mining softwares out there, you can only see this option available in hiveOS, smOS and phoenix miner, you will need to add the rxboost in phoenix miner manually, do some google search on that it not hard

Hello!

Is there any risk to push memory clock higher if stable? Is this actualy wearing down the GPU?

I've reached up to CORE1140 / VDD900 / MEM2280 with stable 28.6 mh/s, without modifying the bios. The card ran at 50°C, 22%fan. 80W reported at hiveOs.
Sapphire Pulse RX 580 Hynix Memory.

Haven´t seen this configuration in other posts, many people claiming unstability after 2250 mhz.

Thanks!

Just tested Core clock 1150 and Memory 2250 - got 31.7 MH/s on Rx 580 card.

that depend in your memory brand & timing are you used and silicon lottery how far your memory can go, assuming samsung memory with best clock is arround 1070/2100

if you lucky enough 2300 is the max you can get  ;D rarely seen, good luck with experiment

All depends on the model, there is some RX 580 that the heatsink dont touch the memory, those burn fast if you put then working at 2100 2200 mhz memory.

Typically, a CO radiator cools the memory of a video card through thermal spacers.
Increasing the frequency over 2000 is not suitable for all memory. Hunix, for example, does not react well to such overclocking, and it is better to flash the BIOS of the video card.
Samsung memory works great with miners that change straps " on the fly".

Hi Guys,

I am running 3x580s on Phoenix miner for a year, but I'd  like to switch to lolminer.

This is what I'm using in Phoenix miner, but whatever I do in lolminer I cannot get good hash rate:


I would appreciate if you can help me setup 580s for lolminer or any other newer/current. I have also tried redminer and i simply can't get clocks to work.

what OS using?

Even if you have the same GPU brand as your friend it doesn't mean you will get the exact same performance from the GPUs, silicon lottery comes to play at times and also the memory type of the GPUs plays a big role too.

Why so many dudes set different voltages for cvddc and mvddc? This 2 running the same voltages, they can´t be different and it doesn´t matter if you set one to 850 and the other to 875 - it will run both voltages everytime with the higher one.

Cap, I'll assume it's Windows :)
Probably old templates are used to configure these video cards for Windows. I haven't used this for a long time.
There is already a lot of information about these video cards on the Internet and mclock 2200 does not work stably on many video cards, because this is a big overclock
