Try to use Msi Afterburner 4.6.2 beta 2 (go to settings/general and unlock voltaje control and voltage monitoring), after adjust to around to -43% power limit, leaving all others (Gpu, Mem, Voltage) stock, untouched.

Check for at least 24 hours of stability, if fails increase power limit from -43% to around -40%.

When found stability, increase mem clock with 5MHz steps at 10-20 hours interval until find max OC stable. Then increase again power limit from -40% to -39% and that's it. Settings are for Sapphire 5700XT.

Do no try for first time to increase memory to 900-915Mhz, it could fail, first find max OC stable, test 24 hours for stability and after go further.

Example here:

Can I use this procedure also for RX 5700 Pulse? I tried to use MSI Afterburner (but I don't remember which version I used..) to decrease the voltage to 0,750V but the value was not set...

Anyone tried ProgPow with RX5700XT? or does miner not support it yet?

Hello friends, I have a problem I am mining with a rig connected to solar panels, this allows me to use the GPU to the maximum during the hours of the sun but during the night I need to restrict the use of these to consume half, I try to use the -gpow command but nothing changes still working the same way can someone help me? Thank you

Rather than using -gpow parameter to reduce GPU usuage why not just disable mining on half the cards in the rig at night.

You can easily create a bat file that will execute at said time and disable half the cards through the device manager and then run the miner again with the half active cards.
Similar thing for the morning where the other bat file will activate the cards back and then run the miner again.
Disabled cards won't consume any power and you can get much better stability this way.

No I never did as its Hynix memory. Its the main card in my multipurpose rig rather than a dedicated mining machine. I try to get less power draw on good hash speed rather than red line it. If im lucky I may get another when they go on the sales but since the profits are now negative its on the long finger wish list.

Hynix memory is so sensitive to memory OC. Anyway, If you can get some reference edition Vega 56 for a really good price then get one.
The reference cards were usually shipped with Samsung memory and they OC really well with better ASIC quality.
Sapphire or MSI will be a good choice.

Hi, do you have experience with the Sapphire RX 5700 Pulse? I can't change the board parameters into the program (4.6c), the board seems to be locked ... especially the memory voltage locked to 0.85V (and Tmem is always approx 80°)... do you have any suggestions?

Memory voltage is locked on Navi cards, also tmem can get high u run card on high voltage, try running card on 1300mhz/750mv and put mem on 900-930, that should lower temps on card alot.

How did you get the card to run at 750mV? Mine never goes under 800mV regardless of -cvddc setting in Phoenixminer. Fan is at 70-90% all the time and power 112-118W.

Same problem...it seems that the settings are not followed by the card...and this reflects on the memory temp (approx 80°C)...

I run it undervolted and Overdriven too, 41 mh/s fairly cool no where near its bench limits. It may be the driver so I installed the latest one to do more testing (19.10.1). It happened after I updated both gpu driver and PM but since the switch, this profile used to run absolutely solid. Dialled it back to test more and will see.

Sounds good. Did you flash 64 bios? It'll make a ton of difference in the hash rate. I was able to hit 1125 mhz in mem clock (samsung memory vendor) but it crashed after a while. So settled for 1095 mhz (stable).

I updated and after a few hours the miner had crashed or the card (vega 56) reset as it was mining about 30% less. Used same settings where it mined perfectly at 41 mh/s for good watts. Just reporting back in case it happens for too many users and a fix is eeked out. On 19.9.3 drivers and this is not an aggressive profile.

OK so it wasnt a one off and happened again about 3 hours in. Is there an auto ramp feature thats tweaking it and pushing it too far causing the miner to crash? After the crash it drops from 41 to 35 Mh/s and uses more power.

Will switch over to see if it happens on another miner.

My sapphire RX Vega 56 is flashed with 64 air bios, then using powerplay tables to reduce the core and mem voltage. Using OverdriveNtool to OC memory, undervolt core and voltages, 65% fan speed.

No issues at all like this.

What are you using to OC? Did you have any other parameter in the claymore bat file for tweaking?

Hi,

I have a problem with ETH mining speed. My miner is connected to NiceHash and when they start mining ETH, first few minutes the speed is stable at around 62 MH/s. After generated new DAG file the speed drops by 10 MH/s (so to around 51 MH/s).

I have 2 Nvidia cards. 1x GTX 1070, 1x GTX 1070 ti

Why is this happening?

It used to happen with me in my 6x RX580 rig. After the new DAG, the hash rate went from 182 MH/s to 179 MH/s. It is not such a huge impact but closing the miner and restarting the system did the trick for me and the hash rate was back.

Also, reset any OC that you have on the card and after the restart, apply it again.

AMD released 19.10.1 drivers. Anyone tried allready? Miner support them?

Working with 19.10.1 drivers.
Vega 56 @ 1110 mhz memory, @1050 mhz core 900mv

When you add support for new AMD drivers, does it mean that these are the most suitable or can we continue to use 18.6.1 for example?

you can but your better off using newer drivers like 19.+ there's not much diff tho other then maybe a bit less power an stability

hey guys, i have a question, when i use your miner on nicehash, i get alot of rejected or invalid shares , along with good ones, but im trying to find out why. When i mine ANY coin i get no errors or invalid shares nothing all good 100% only have this issue with nicehash do you guys have any idea on what this could be? also when i use nicehash for mining i set -coin auto along with other settings but is that the issue? thanks for any help
