RX6700 problems

[Le_nox]

Hi there!

A year and a half ago I bought a RX 6700 and I've been having an horrible experience with it. As mentioned below, I use 4 monitors where one usually has a tab from Twitch or Youtube. If for some reason I open another tab of Youtube for exemple, both videos will be lagging a LOT. Whatever monitor they're on. Same if I open a webpage with some animations (this include some media players: if the HUD? of Youtube is showing while the video is playing, the video will lag until it disappears), everything will lag for some time. In top of all that, when I press Alt+tab it's all buggy, even if I have only one Twitch/Youtube it will show like 7-8 of that tab. Few screens of this mess: https://imgur.com/a/GNNzvK9 (the screens are on Opera but the same happens on Chrome + Firefox, I just can't stand these web browsers). I've deactivated the hardware acceleration on Opera and it's now usable, but I still have all that.

 

Sometimes the fourth monitor won't even be recognized anymore. I don't turn off any screens, I'll have to reboot maybe 5 times in order to get it to be detected (already tried to turn them off and everything but still the same).

 

It struggles with a few games too, which I can't remember now from the top of my mind, since I've abandonned playing on PC and switched to the Steam Deck and Ps5 because of this GPU.

 

Here are the specs of the PC:

GPU: Sapphire RX 6700

CPU: Ryzen 5 5600

Motherboard: Asus ROG B450F

RAM: 2x16GB CORSAIR

PSU: Nox 650W

Monitors: Main 1080@144, other 3 1080@60Hz

Operating System & Version: Windows 11 23H2

GPU Drivers: Adrenaline 24.2.1

 

I have already tried this:

- Uninstall drivers with DDU in safe mode.

- Updated from Windows 10 to Windows 11 23H2.

- Switched all cables, bought new ones, changed from DP to HDMI all screens, etc.

- Main monitor switch from 144 to 60Hz like the others 3. Even while using only two monitors at 1080p@60 each, still the same.

- Updated BIOS and chipset.

- XMP deactivated and reactivated.

- Turned off Freesync on the main monitor.

- Someone on Reddit advised to turn off MPO, it kind of helped but the Alt-Tab thing is still happening.

 

I'm about to switch back to Nvidia since it doesn't seem that the card likes multi-monitors setup, but am I missing something?

Thanks in advance if you read all this!

I have the same RX 6700 (very similar system overall, tbh), and haven't had any of those issues. The only one for me is that once in a blue moon, my main display won't power up after turning on the PC. Reseating the cable fixes it 100% of the time, so I'm guessing I just have a bad cable and am too lazy to fix it. I've run 3 displays off of mine in the past, never tried 4. I'm assuming you've already disconnected and reseated the PCI-E power cables in the card and, if applicable, the PSU?

 

You should still be in RMA territory. If so, I'd probably do it, because it reads like there is something wrong with the silicon.
