Hot memory RX 5700

[Moonpie2]

So I'm kinda new to actually having modern hardware inside my PC and am unsure if a 100 degree memory temp is right... or even if MSI Afterburner is reporting right on Navi cards?

Does anyone know if I should be ramping up my fan curve even more of if that's normal?

The memory should only go to around 86c on the 5700 series. However Hardware Unboxed (Australian YouTube channel) recently reviewed the Asus TUF Gaming which was hitting 104c as it had a terrible heat spreader covering the memory but with no fins to dissipate heat. I don't think they have reviewed your specific Asrock model yet (they mainly reviewed the high end coolers from various manufacturer) but all the others besides the Asus TUF Gaming peaked at maximum 86c like the reference AMD cards.

Yikes.
Maybe I can message Asrock and ask them what's up with that !!

I'd change it to something like that, the fan can stop when the temperatures are low. There is no need to spin all the time at 20% or more.

Ok, I'll re-wangle the curve.
Makes sense.

I did just discover though that there's a difference between mining and gaming when it comes to memory temps.
10 minutes of mining was giving me the crazy temps.
But I just ran Superposition twice back to back and the memory temps never got higher than mid-70s.

Hmmmm.......

Hmmmm.......

Isn't mining no different to running a intensive benchmark 24/7? It's an unrealistic usage of the gpu as it will never technically hit 100% all the time?

Well, I just figured that using a GPU at full oomph (regardless of mining or graphical benchmarking) would be identical.
Now I've learned that's not exactly the case. Memory seems to be getting slammed much harder in mining. Who knew?

 

[Moonpie2]

FYI for those who are interested, Asrock tech support got back to me and said 100-105 degrees is what 5700 memory is rated to go up to.
Sooooo.... yeah.
Toasty !!!

What are you mining? Some algo's are memory intensive but they can also be dialled back so your temps can be realistic.

Yeah, absolutely not, for example.... run furmark with x8AA and the card is much cooler at say 30fps, than with no AA running at 150fps. Both running at 99%

Eth usually.
Do you know what what command line to add to the config file to make the memory a little less stressed?

Its normally intensity. So you set it to a lower number. Other option is to just dial back the memory speed both of which can be done through the miner or batch file.

 

[Moonpie2]

I read the readme and tried the command line, but it seems that my RX 5700 doesn't like being told what to do by a miner.

So instead I just dialed back the memory frequency by 50mhz in MSI Afterburner and that's keeping my temps lower than 100 while having no effect at all on the hash rate

 

[gpuerrilla]

winner solution!

 

[Moonpie2]

Actually, I take that back, it looks like ambient temperature changes kept it under 100.
Hahah

Still, lots of other command line stuff to tinker with

 

[gpuerrilla]

For the sake or a few kilohashes, your better off finding the best power per hash and keeping the cards both cool and less stressed. If its done from undervolting, lowering intensity or improving your airflow you will not have as many issues. When you red line the hardware all it takes is the latest miner version to throw it off and you end up losing because of more downtime.
