hehe I do speak russian Smiley)
And I think you do too Smiley)

Looking for good prices for GPUs - it looks that prices got much higher Sad

I am Smiley)

Want to move to this electricity provider - https://join.bulb.co.uk/join/quote
Much cheaper (but with this ETH price - it doesn't matter much)

Skills - should be alright - occasionally assembled PCs and Servers from scratch (as a hobby and as my job). Never used Linux though

Thanks for the tip about GPU limitation.
Found an article that since november x12 GPU (AMD) should work fine http://www.aurelp.com/tag/how-many-gpus-does-windows-10-support/

Guys, do you think setting up rig 1x Mobo 12x GPUs - is easy enough to set up?
(in theory - it is the same as 1x Mobo and 2x GPUs - but a little more work with the wires and flashing them)

What's your opinion on this? Any caveates?

Thanks for the article. Really helped to boost to 28.3 Mh/s in single mode (at 74 degrees C, 95 watt)
Not getting any hash errors.

I wonder if you have sufficient power/volttage on the cards.
Do you think that you have sufficient PSU?

I remember similar issues with DDRAM (depending on sequence, placement) - I was "losing" RAM till I found that stronger PSU solved it

NB: going to install more GPU, will report back with my findings (so far running just one)

Cheers

There are such KVM (keyboard video mouse) devices that can do that. But they are expensive.
Alternatively there are Mobos with BMC (Baseboard Management Controller) from Supermicro for example.

They all communicate via IPMI

Google all of these keywords - and you'll find what's best in your case

Hello all,

I have got a rig of six Sapphire Nitro+ RX570 8GB. I have modified and flashed them with one and single bios. Now every single GPU is hashing at the rate of 28.8+ and power consumption bellow 110 watts and temperature not reaching 60c. Process clock: 1125, memory clock: 2000. Two gpu's not giving a single memory error and the other four is throwing errors but still keeping hash rates stable.

How is this possible that one and the same bios is working differently on 6 and the same type of GPU's. How to resolve memory errors? Should i try to overclock problematic cards at the lower levels?

Any suggestions?

I'm trying to reach your results on same cards - and having hard time getting beyond 25 mh/s (Anorak mod OR Polaris OneClickPatch BIOS Mod)
Which BIOS mod did you use?
I want to try and see if I get same errors with same speed

Dual or single mining? For some reason on my 570 I'm getting about 25-26 MH/s either way, so I'm dual mining on mine (right now ETH & DCR) Getting 25.5/635 doing that. My 580's I get about 30.5 single and 28.5/450 (have to lower dual mining on the 580's... no clue why) dual.

All single mining (ETH)
My card is Sapphire RX570 8GB Samsung. Can get to 25, but not 26. Something is off with the straps.
Need to look into it.

When dual mining - gets me to 24.8/740 (ETH/DCR)

Which BIOS mod are you using?

it should be higher for an RX570, which driver do you have? Use the Aug23 Blockchain driver or get the new Adrenalin and switch to "Compute" mode in the AMD global settings...

Tried the latest driver - had 24.9 at best (compute mode)
Re-installed the Aug23 Blockchain driver - running at 25.3 Mh/s

Now I wonder if I can get any better at all.
Planning to try some new BIOS mods (haven't seen any appropriate though except Anoraks)

Guys what Mh/s do you get these days?

I've read that DAG size affects the calc speeds. Have you been affected by DAG 160?

My speed (overclocked and BIOS modded) is 25.3 Mh/s at the moment. I wonder wether I can get better out of the card :/

Thanks

Getting 25.3 Mh/s ETH, on RX570: running on 1150 / 2000, -93 mV, PowerLimit -15%

Is it the best what I can get on DAG 160?
Anyone has a better result on RX570 / RX580 ?

Thanks
