I would like to know how to undervoltage my ColorPower RXs, one have lower power consumption and more hashrate than second and both have the same settings. Is possible to make ~120W and 58.5-59MH/s per card and does my setting are actually good, will not brick GPU for some months?

Have you tried to measure the power meter? How much does your car really consume?

Samsung did not manage to overclock as well as micron, but it has the advantage that it consumes less.

Show me micron straps
A good overclocking result for how many days has it been stable?

3

the wattage shown is totally nonsense and random. you need to measure at wall to get your real power consumption…unless you dont, you cant verify undervoltage.
best way to save some watts is to reduce soc clock speed

4

About 7 days its working and stable. I know thats not real power comps but i know at wall its +/-65W addtional.

5

I would like to save mh/s and get lower power comps. Like this:

6

if one card shows 95 and the other shows 125
this does not mean that it actually consumes much less.

you were asked to reduce the frequency of Soc.

show me the bios from one and the other card, and we will look for why such a gap in consumption.
2 questions.

1 card is really Saphire. or a card from another manufacturer but the BIOS is loaded from Saphire.
2 reduce the memory frequency to 912. hash will fall but check how much consumption will decrease?

I set memory frequency on 912 and third card(ATI samsung memory) get crashed and miner shut down.

9

samsung very rarely keeps such frequencies,
how consumption per micron has changed.

and check what frequency it actually sets
amd-info

10

about 120w per micron

!!! SOC: 950 MHz

I didn’t bother to squeeze out the last MH.
my micron memory is not stable at 930. at 925 it can work for several days. then job loss.

I turned the frequency down to 912 then SOC do not go higher. But in the BIOS, I registered the maximum frequency.
it gave a little savings.

12

I have modded bios, maybe that’s the reason of problem. I really dont know, this card is PowerColor Red Dragon if it would help somehow.
So what should i do…

13

set 912 to micron memory.
check amd-info
What frequency does SOC work on?
Did you lower it to the BIOS?

reduce consumption to 98 how samsung works you probably won’t succeed, but 10-15 watts can be removed.

this once again confirms that you did not reduce the SOC frequency in the BIOS.

you need to set the maximum frequency of soc 950 in the BIOS editor, reduce the voltage of soc.
maximum voltage soc.

16

You mean OC? And what voltage should i set?

17

I’ll drop you a video there, everything is well described.

The essence, I think, will be clear, at different voltages and at different frequencies you can see what hash and consumption you can get.

I recommend choosing the best option for yourself and stitching it into the BIOS.
