All,

Quick question, is anyone else experiencing instability with the RX5700XT?

It will sit at 51mh/s for a few rounds and then drop down to 21, 8, 9 before going back up to 51mh/s

Power Limit -45%
Memory Max Frequency 910
Core Clock Frequency Auto

Checked Board, Riser and PSU with no luck

On latest drivers and Claymore version


Anyone had any luck with this?

Not crashing but the hash rate isn’t consistent?

Reference card 5700xt, Tried using afterburner and wattman to adjust clocks and power with no luck.

PM has rocksolid hashrate at 52.7mhs with: -tt 58  -cclock 1300 -cvddc 750 -mclock 910 -hstats 2
and only 76 degree C mem temperature

I keep seeing you post this. (Repeatedly)
What's your environment? I can't get anywhere close to your results. I've tried everything.

Mine is three cards, spaced about 1 inch between on a frame with two 120mm Hydra fans (185.87 CFM) blowing directly on them at full speed.
They're in a hydroponics tent with two other machines and the ambient temperature ranges from 110F to 120F.

This command has been working for the past 21h 33m.
-tt 58 -cvddc 800 -cclock 1300 -fanmin 0 -mclock 875
But only get 49.2MH/s for each card on average.

If I attempt to raise to -mclock 910 then my second card reduces to 0MH/s.
No matter what my -tt is set to it never makes any difference for me.
I use -cvddc 750 instead of 800 and ofcourse PM instead of claymore. The temperature in my room is aboit 22 degree C

So about a 30F-40F (24C) differernce in ambient temperature. I'm literally blowing hot air at my cards. LOL! (I have another inline duct fan arriving tomorrow to exhaust some of this heat. )
But when I try to go beyond 900Mhz I get the "watchdog" message and it quits then I frequently need to hit the reset button because sometimes it freezes up the whole system.
I'm currently trying -tt 58 -cvddc 800 -cclock 1300 -fanmin 0 -mclock 890 and I'm pretty stable for the time being. I'll try to reduce my -cvddc to 750 next and check my stability.
