Re: RX 5700 XT memory clock stuck causing high temps when idle

Jump to solution

Funny, they say in idle it should be at 875 but it remain stuck at 1750 on on 144Hz. This is really something they need to look into. As it's happening on popular monitors such as the LG UltraGear 27GL850

Re: RX 5700 XT memory clock stuck causing high temps when idle

Jump to solution

Was browsing techpowerup's forum...true story bro.

2018-09-18: W1zz identifies high idle/multi-monitor clocks and hence power draw on RTX 2080/2080 Ti
2018-09-27: NVIDIA issues a driver update that fixes the high idle clocks, but not in multi-monitor
2018-11-08: NVIDIA issues a driver update that fixes the multi-monitor clocks too

NVIDIA: under 2 months to completely fix a high multi-monitor power consumption issue on 2 SKUs.

Meanwhile, in the red camp...

Shortly after the Big Bang: people complain about high idle/multi-monitor power draw with AMD GPUs
After the heat death of the universe: AMD actually acknowledges, but does not fix, the issue. Explanation given is "drivers r hard mkay?"

I had this same issue as OP.

I managed to solve it here:

"Blanking: 80" works :)

Can AMD fix this settings with a driver update (without CRU)?

Would be better than Third-party software.

I think these settings are pretty monitor dependent.

But Nvidia had the same problem and they could fix it with an update

Last time someone mentioned nvidia they said they were doing the same thing with multi-monitor setups. Having more than one plugged in ramps up memory to this day.

Yes they do. On 5700 XT i heard of report of   2x 144 hz being idle.

I'm going to return this video card. I highly advice anyone who has the chance to do the same.

You do that. I bet your Nvidia card is going to do the same thing until you change monitor settings.
