Custom Resolution Utility (CRU)

[progamingnoob]

- Used this program for years, but lately I've been having a weird problem.

- On my BenQ XL2546, I'll make a blur busters vertical total tweak for 182hz, select it in the nvidia drivers, everytime I reboot it resets the monitor to 144hz, even if I delete the 144hz resolution inside custom resolution utility, very very weird.

- Quick Update: Replaced my displayport cable and the custom refresh rate is saving after reboots now... very weird stuff.

Hi everyone, and thank you ToastyX for cru.

I used cru for a long time, but now with my new gpu i have a problem.

My Specs:

gpu: Nvidia 1080ti
monitor: Acer XR342ck 75Hz Freesync (48-75Hz Freesync range) DP1.2


With Amd cards, i was always able to overclock the monitor with cru, to 100Hz and a freesync range of 35-100Hz.

But now with Nvidia, if i set it to 100Hz via Windows after setting everything with cru, it always goes dark and resets.


Can anybody help me ? I want this sweet 100Hz back ...

Thank you


Here are my settings:
(It also don't work if i make a normal detailes resolution. And everything beyond the standard 75Hz won't work neither)

The FreeSync data block is for HDMI. DisplayPort FreeSync uses the range limits in the display properties, which you can edit using the "Edit..." button at the top of the main window. The first data block should not have an HDMI data block if it's DisplayPort. I also don't know what limitations NVIDIA might have with FreeSync. NVIDIA typically could not run certain FreeSync monitors at higher refresh rates without the monitor skipping frames, which means the monitor could not do higher than 75 Hz with NVIDIA cards, but that was before NVIDIA added FreeSync support.

Hi. Thanks for answering.

Yes, i am using Displayport.

These are the things i did.:

1: Changed the range limits in detailed resolutions

2: Created a custom, detailed resolution for 100Hz

3: Deleted the freesync data block

But still, if i try to change the refresh rate, either in Nvidia or Windows control panel, the screen goes black (no signal) and then resets back to 75Hz.

I tried different Hz rates / ranges above the original 75Hz, with no success.

Do you know what i am doing wrong ?

Thank you.

I don't see anything wrong. NVIDIA's FreeSync implementation is not exactly the same as AMD's. NVIDIA might not be able to drive that monitor at 100 Hz even if AMD can.

Ok. Well, it's a pity. If you ever create a workaround, let us know. I would even become a Patreon. Thank you.

Hey, I've got an issue with my newest RX580 Nitro+, I previously had 290X and GTX660, after using drivers patching and CRU I was easily able to overclock it to 80Hz from 60Hz, now I can't at all on 19.1.1, 19.4.1 and 19.4.3 driver versions. When I started testing out monitor overclocking I tried DVI-D Dual Link -> DVI-D Dual Link, HDMI -> DVI-D Single Link and DisplayPort -> DVI-D, on DP and HDMI it's easily doable, on dual DVI-D after exceeding 63Hz screen is completely blurred and above 65Hz did not work at all. I'm using HDMI -> DVI-D Single Link currently (the same as I've always had) but I can't get any Hz more at all, both from using CRU and Radeon Settings. Monitor has DVI-D and D-Sub only (BenQ GL2250) but given it worked previously it must be something related to AMD drivers I think or on GPU side. Changed max pixel clock to 600MHz, V rate to 90 in monitor editor tab, added extension block with a data block including override maximum TMDS clock to 600MHz as well, but to no avail.

Any help? I'd seriously rather not going permanently back to 60Hz.

The procedure should be the same on all three cards. Did you patch the driver? Don't add an HDMI data block. DVI monitors usually can't handle HDMI signals. The only way to exceed 165 MHz pixel clock with single-link DVI is to patch the driver.

That's the problem as I wrote, I did that and after reopening the patcher it shows everything got already patched.

I'm trying to figure out what you did before vs. what you're doing now. You said before HDMI-DVI and DisplayPort-DVI worked but not plain DVI, which doesn't make sense to me because they should all work the same with the patch up to 230 MHz. The 63 Hz limit doesn't make sense to me either because people usually don't see a problem until 67 Hz without the patch because of the 165 MHz pixel clock limit. What's the current limit you're seeing with HDMI-DVI? Export a file showing what you tried. Does your RX580 have a DVI port? If so, try plain DVI with the patch.
