Custom Resolution Utility (CRU)

It does appear that this chip isn't able to support VRR. I'll have to look out for an adapter that does use ps196. Thanks.

I saw the maximum pixel clock of my monitor in CRU, where you can check the monitors informations.
I tested both cvt-rb and cvt-rb2, and both of them make the VRAM frequency go down to an acceptable level.
My question is: is it better to choose CVT-RB, and exceed the pixel clock of my monitor, or CVT-RB2 which is almost the same pixel clock of my monitor ?

The limit reported by the monitor is not important. The monitor probably uses DisplayPort HBR mode with 4 lanes, which supports up to 360 MHz pixel clock at 8 bpc, so you can use either CVT-RB or CVT-RB2 at 144 Hz without a problem. If CVT-RB2 works fine, use that. If you exceed 360 MHz, the color depth will automatically drop down to 6 bpc, so if that's happening when using CVT-RB with AMD's software even though the pixel clock should be below that point, then it must be a driver bug.

Okay, thank you very much for the information

Hi there,

I was hoping to get some help. I have tried a few different tutorials posted online and on forums, but I have been unsuccessful in adding 1440x1080 @ 390hz as a custom resolution. I have the following:

• Acer AOPEN Fire Legend 25XV2Q 390hz monitor
• GIGABYTE AORUS GeForce RTX 3080 XTREME
• KabelDirekt 10ft DisplayPort, DP 1.4, VESA-Certified
• Windows 10 21H2
  

Someone posted this video (https://www.youtube.com/watch?v=IZEM6Qhw0N0) of them applying this custom resolution to their Acer Nitro 390Hz which is supposedly the same panel.

I don't know if that is even the best way to force display scaling at those resolutions for a refresh rate as high as 390hz. I have been able to create a custom resolution of 1440x1080 in the Nvidia control panel, which I believe creates the resolution and timings at 60hz and then GPU scales (I could definitely be wrong). However, it deletes itself after I restart my PC so it isn't much of an alternative. Maybe that will give some insight as to what is going on with everything. Thanks in advance!

Unsuccessful how? What happens?

The res just doesn't appear as a possible mode. No errors or anything. Just doesn't show up in the list.

Then you'll have to show me exactly what you're doing. Export a file with the changes and post it here.

Hi, I'm just trying to do something modest.
I've buyed some time ago a monitor that says 165Hz in the box, the guy that sold me says that I have to overclock it to reach that.
Now I'm here, when I add a Detail resolution 1980x1920@165Hz with CRU (with the timings [Automatic (PC)])
It doesn't appear as an option when I restart my pc/ execute "restart64.exe" in any place.
What's curious is that, now in my Intel Graphics Command Center appears listed as a supported mode, but I still can't change my monitor to 165Hz, why is that? how can I fix it?
Thanks for the work on this program
(I leave my Exported .bin file in here too)
- Intel UHD 730 Graphics
- Monitor WP-M0270 (A peruvian brand bought from a chinese OEM and sell it to me, it has a dead pixel and they were selling it very cheap because of that )

That means the driver recognizes the resolution but there's a bandwidth limitation. Are you using HDMI or DisplayPort? HDMI 1.x is limited to 340 MHz pixel clock, and I don't think that monitor has HDMI 2.0. The monitor probably only supports 1920x1080 @ 165 Hz with DisplayPort.

I have attached the default file that generates on a complete reset and my attempt to add forced display scaled 1440x1080.

You need to read the part about extension blocks.
