Topic: 6 x RX 570 Red dragon RIG - OVERCLOCK (Read 1107 times)
Yes, the switch should be in the position closest to the video output ports.
There is a dual bios switch on the cards. Do i have to slide it to the right and then flash the bios ?
I have the same Powercolor Red Dragon cards with Hynix/Elpidia dual timings. On Windows 10 with the AMD blockchain drivers for ZEC I get ~315 H/s with a 1325 MHz core clock, 1950 MHz memory clock, -96 mV undervolt and -15% power limit in Afterburner v4.4.0 beta 19. The bios was modded with the Polaris Bios Editor v 1.62 'one click timing patch' from jaschaknack. If you can't undevolt the cards, remove the drivers in safe mode using DDU and try again after installing the blockchain drivers. If you have a bios mod, for RX 570's you also need to run the pixel patcher to bypass the driver signature check.
If the card crashes after it starts mining, try lowering the memory to 1900 MHz and the default 1250 Mhz core clock. For ZEC it shouldn't make that much difference.

Memory type is elpida on all of them.
I solved the problem. I changes the virtual memory from 16 to 24 GB's.
Now all my cards run @ around ~ 270-280 h/s.
I would like to get 300 out of them.
But i don't get any higher rates out of them with highering/lowering cclock. Highering memoryclock.
Etc...
Do i need to change settings in BIOS. Or do something else?

OK, so you have the best motherboard available to date for mining in my opinion and I have seen this board supports overclocking.
To check for 6th card, do the DDU thing I told you earlier.
After that check with GPU-Z each card what kind of memory have, if the one offering a lower hashrate have a Hynix memory then there is not much you can do through Afterburner utility, memory and clock will go up but result will be same hashrate from such card.
Keep in mind that you need to have all Windows updates which are a lot since you have done a fresh install. They impact a lot the performance of Windows 10 especially in mining.
Also last thing maybe the riser, try replacing the riser of the last GPU, the one who gives you lower hashrate but highly unlikely if this card happens to have Hynix memory.

For mining Zcash the amount of Ram is not important as long as you have at least 4GB of RAM DDR3, but 8 GB is the recommended amount.
What memory has this GPU-0 of yours ? Check it with GPU-Z program, if it is Hynix it doesn't care if you overclock it or not through Afterburner it will not show you higher hashrate. That's a known problem with Hynix memory.
If it doesn't recognize, your 6th GPU, you can try DDU, direct display driver uninstaller, then restart and reinstall the drivers. It should recognize it now. (it may not recognize all cards directly, some may show, as VGA Basic Adapters, click on them and Update driver until all are recognized)
Also tell me what motherboard do you have, some motherboards do not support overclocking all the cards.

Very complex question, but you can find detailed description here

I was trying to overclock my cards, but my screen black screened alot so
did a fresh install of windows, now my GPU 0 isn't working anymore....
Only 5 out of 6 are showing atm.... now what?

Do i need more memory to mine Zcash, only have 4GIG on the MOBO atm.
How do i flash all my cards? I can only see 3 of them on ati winflash?
use commandline atiflash, but you can't flash all at once. the help is good enough to find all that's needed yourself.
The BBT video I linked shows you how to do it in Powershell.
How come in the video the guy is lowering his ccore clock, and you are highering it. When i use 1325mhz, my pc screen blacks out, when i use 1300 i'm getting a lower hashrate.
How do i unlock my voltage core, on Afterburner
Which intensity are u using ?
So far i'm not getting over 275 h/s. And GPU 0 is still hashing at a lower rate then other cards...
Yeh i used the commandline but i pressed x after i flashed. And flashed them all at once.....

Okay, thank you i'll try it out and see what happens with my hashrate.
Yes, with RX 570's you need to run the pixel patcher to bypass the driver signature check with a modded Bios. It's up to you if you want to mod the Bios. It mainly helps with memory intensive algorithms like ETH or XMR. For ZEC you can try it with and without the Bios mod, but like I said it shouldn't matter much.

Ow okay, do it need to run the patch, i saw a video saying it won't work without, on the 570's.
Do i need to mod every card?

Okay awesome. Will try it out.
Did you mod your BIOS. Or is this only for ETH mining done ?

For ZEC mining it shouldn't matter much if the Bios is modded or not. My Red Dragon Bios is modded with the PBE v1.62 'one click timing patch' from jaschaknack.
