Hi all, I am hoping you guys can help. I have just built a brand new system and I have having a number of issues with my 5700 XT Red Devil. The main issues are firstly when I run a game I am getting a really high pitched multi tone noise coming from the card which sounds like some 8-bit game/dial up modem. The only way I have ben able to semi stop this is to cap the framerate to 144 or below in the radeon software but it doesnt go completely and surely I shouldnt have to do that? I don't know how well you can hear on the video but it is making the noise and then halfway through I am loading the benchmark under Rainbow Six Seige and it gets much louder and different tones: https://imgur.com/a/XqaUD22 Secondly and equally as important, when I am running a game (at the moment tested Rainbow Six Seige and Borderlands Pre-Sequal) the game is very choppy and stuttering. My old nVidia 750ti run everything smoothly which should be a pile of junk in comparison. I have a completely clean install of Windows 10 using the latest drivers 19.12.1 and this is without any other software running other than Steam/Ubisoft to launch the games. Radeon software is running defaults (except when testing the framerate lock to 144fps) My specs are: Powercolor Radeon RX 5700 XT Red Devil 8GB Ryzen 5 3600x (stock speeds) MSI B450 Tomahawk Max (latest bios) Corsair Vengeance RGB PRO Black 16GB 3600 MHz AMD Ryzen Tuned DDR4 (XMP on) Corsair RMi Series RM650i 650W '80 Plus Gold' MSI MAG241CR 144hz monitor (freesync enabled) WD Black 500GB SN750 M.2 2280 NVME PCI-E Gen3 WD 1TB SSD - Blue 3D NAND 2.5" The bios is on optimised defaults with the only changes being enabling XMP and setting the Cool n Quiet to enabled from auto. The video card is plugged into my PSU with a single cable controlling both 6+2 ports( I have read that 2 maybe should be used but Corsairs forum states that 1 is designed for that purpose and will be fine). I am now not sure if it is a fault card or something else I need to change to get this to work properly. It has been many years since I have had a nice card to use so taking all advice on settings for everything to ensure this is setup correctly. I am a bit of a loss as to what settings should be enabled both in the radeon software and in game. Should I be using freesync? The radeon software recommends a number of settings but should I have vertical refresh off, always on, enchaned? Lots of settings but no obvious explination as to what they do. I am hoping someone can help me. I don't want to have to return it, I was looking forward to being able to finally game without everything looking like minecraft. Thank you. EDIT: forgot to add running 1920x1080 @ 144hz with everything highest settings (reducing during testing for noise).
