OK, that riser has several power connectors…

Which one are you using? 1, 2 or 3?

[minerlithuania]

im using 3

[farkeytron]

Can you try using 1 or 2 (preferably 1)?

SATA power connectors for mining is a very BAD idea.

[minerlithuania]

yes i can do that

[SrMorte]

You should, only if you wanna make a fire with the SATA connection.

[farkeytron]

It’s not just a fire hazard to use the SATA plug to power your risers, it can also waste power.

Sometimes, high resistance (like what is caused by the SATA connector) can increase the power usage of a rig in the form of heat.

Use connector 1 (or 2 if you’re desperate), but never use 3.

What are your clock/voltage settings in HiveOS…? please share a screensnip of the relevant GUI section.

Here is how i have my 570 set up for the power options.

I am at 91w (i had things turned down alittle and was pulling 85w but wanted to get 30mh)

Before these settings i was running 135w on this card.

[minerlithuania]

Everything would be good if electricity usage would be ~500w

[farkeytron]

Did you change the power connector on the risers yet?

Also, your VDD is actually kinda high… try getting it to 800mv or less, if possible.

Also, are all your cards running a custom BIOS? I know on my RX 480 8GB cards the VDD is locked at 1000mv because I am using the stock BIOS in Winblows. I used a proggy called WattTool to lower the voltage offsets on-the-fly to get under 1000mv

I saw you have gigabyte rx580 8 gb and you mine with 30 mh. My gigabite mine with 21.5 mh.

Tell me a solution ? my video card has hynix memory.

[minerlithuania]

Im using custom BIOS ,but when im trying to make 850 on RX580 miner crashes if i make 800 on RX570 crashes miner…

[minerlithuania]

Hey just download PolarisBiosEditor it have one click button, upload new bios and use 1150 2100 or 2150

[imobfad]

i need to pay 65 euro to software.
ok.

[minerlithuania]

I have changed power connectors same shit…i dont understand why such a big usage of electricity…tried everything…

[minerlithuania]

you dont need to pay euros … the software is free version

The one-click timing patch should apply the straps for better RAM performance.

You shouldn’t need to set the “ref” when you’ve BIOS modded the cards. Try removing the “ref” value and see if your hashrate goes up.

If it goes up, try lowering your clock speeds and voltages even further.

Also, the timing patch allows you to run the RAM at a lower speed and get similar performance (with less power consumption)… I’m running my 29MH/s RX480 with 2050 mem speed because the timings are so tight that I get memory errors above that (in HWINFO64).

I went back and looked at your specs… your PSU is over 5 years old… Do you have another PSU you can try? Maybe borrow a friend’s? You know, as PSUs age, the capacitors lose their effectiveness and will affect the PSUs efficiency.

i Have changed bios of RX570 and now 500w

Hi, i have an AsRock 570 8gb Samsung memory, i was mining @29.43 mh/s and 83w. my settings
