Hey everyone,
I am wanting to Overclock my cards. I have 4 RX570 GPU's. 3 of which are Hynix, and 1 is an Elpida memory which I can't overclock without crashing the rig.
Is there a way for me to overclock the other 3 cards? I have done them all individually with MSI Afterburner, but when I start the rig up I don't think they are overclocked anymore. I am getting around 25Mh/s of hash on each of the cards, but I was hoping to get to around 28 or 29 if possible.

AfterBurner has to be running after the reboot.  Did you set it to run at startup?  Just look and see if your overclock settings are still there in AfterBurner after the reboot.  If not, I guess you didn't save them.

If I open up Afterburner, I don't see any options for my cards. The 4 GPU Cards show up but everything is greyed out and I can't change any settings.

Please Clarify, from your first post you've done overclocking, so now its now greyed out?


There is an option in MSI afterburner to start the App in startup, what you need to do is to save first your Overclocking setting by clicking the floppy disk Icons and tick the windows startup option.

So when I was overclocking originally, I did it one card at a time and it worked fine. Now, when I have all 4 cards connected, it is greyed out and I can't change anything.
I did one card at a time, and all my Hynix cards worked fine but the Elpida one would crash on me.

How about installing the hynix card first? can you do overclocking?

there is this settings in the MSI AB to untick the Synchronized settings for similar graphics card in order to set clocks individually.

I am just wondering on the greyed out issue, that problem is seen in incompatible driver to MSI AB versions, however you've told that its working on 3 gpus so its kinda weird.

I've been down the road of settings overclocks everytime I run my miner; and that is one heck of a frustration especially when you have different cards.

Find your good overclock settings and then set them in the BIOS. That makes it much MUCH easier. No messing with settings. Just run the miner.

The 4 GPU's worked when I used them all individually, just not when I have them all connected. I only have 1 Elpida card and 3 Hynix cards. Not even sure why since I ordered them all from the same link on Newegg.
I will try unplugging the Elpida card and see if Afterburner works on just the 3 Hynix cards.

try blockchain driver

Where/how do I get that?

I have never had much luck overclocking multiple cards at the same time. It has always worked better for me to do one card at a time. It can be a slow process but worth the wait.

Do the settings save though? It seems when I overclock one card at a time and then reset the computer, my overclock settings change

I think that is it without a doubt.  If you are running that many cards you simply need to bios mod them 1 at a time

The only thing I tried changing in the overclocking was my speeds. I was using 1150/2100 and got the best speeds that way it seems. How do I do that with Polaris?
