Dual Monitor Setup Clock speed Question

I now setup a new Desk and have more than one Monitor I plan to use all the time now. Everything is going smooth but I now notice I have the high Memory clock speeds :D and I idea around 46c

Monitor one is 1080p 60hz HDMI Upscaled to 1440p "Same clocks has 1080p"
Monitor two is 1440p native 144hz DisplayPort

I always knew about high clock speeds when running more than one monitor but I never really looked into if they was a fix/hack you could do does anyone know anything that can be done?

Thanks

This was mentioned in a thread recently and seems to be an nVidia driver problem that has persisted for years. The easiest workaround most people suggest is setting your 144 Hz monitor to 120 Hz instead. There might be other solutions though depending on your setup:

not only does shankly not have an nvidia card, but as an nvidia owner I can confirm that this isn't an issue any longer
 
I didn't find a solution to this (other than switching to Nvidia).
Just learnt to live with it. Not sure if I get the same issue on my Fury X cards. On my 290X I had a 1440p@60Hz and a 1080p@60Hz setup, on my Fury X I have 1440p@144Hz and 1440p@60Hz. Wondering if it's resolution or frequency that causes the issue.

I have always thought this been an issue for any brand?
I reading msi and can change the default clock for 2D?

It's either. Over the years I was running my multi-monitor setup on AMD, the memory only downclocked when all monitors were equal resolutions and frequencies. 3 x 1920x1080@60Hz and one 1920x1200@60Hz meant high idle clock, but changing the fourth to a 1920x1080@60Hz (different monitor completely than the others) and idle dropped nicely.

I remember once the idle jumped back up and I could not work out why - until I found one of the four monitors was running at 59Hz! Changed that to 60Hz and the idle went back down.

Shanks, any option of putting the non-gaming screen onto a motherboard output so you've only got your game screen on the GPU?

All I can tell you is I switched my 290X for a GTX 980 (rest of PC the same and same monitors, 1440p@60 and 1080p@60) and the GTX 980 memory clocks are idling as I write this at 324Mhz (they max at around 3500Mhz.

I think looked into using Afterburner to set 2D clocks but as I recall it didn't let me set the clocks (core or memory) as low as they should idle.

This is something I was thinking on doing and that would work my i7 3770k has onbos graphics. But right now I have the second monitor downsampling from 1440p and it looks really good and it makes it easier to switch between they screens when they the same resolution.
Can Intel graphics do downsampling?

I ran with high memory clocks and there weren't any issues, except the high idle temps. So you could always just try to ignore it (it's what I did).

Interested to know how you get on with using Afterburner (or something) to manually set the 2D clocks though.
 
Wondering if you managed to get this sorted (or if you just decided to live with it)?

I checked to see what my Fury Xs do, but the memory just seems to be 500Mhz and the slider won't even go lower, so I'm not sure if I'm experiencing the same issue or if they just don't go below 500Mhz.
 
Just put up with it for now. Going to try the Intel GPU out and see how that works if not I'll just after deal with tramps extra 10c when not gaming.
Temps have not changed when running games. If Intel can downsampling my res to 1440p like amd drivers can I'll be OK with that.
