    New RX 480 - Low Usage and Performance Issues

    rezhyn

      Hello,

       

      I recently purchased an ASUS RX 480 OC to replace a old 660ti. The rest of my system is up to spec for this card (see below) but ive had nothing but performance issues with this card. After an entire weekend of troubleshooting I believe my issues are due to the card not staying at high usage as seen from MSI Afterburner. When I watch benchmark videos or normal gameplay the persons usage stays at 99 to 100% however mine will frequently drop to basically any number whenever it wants. Now I dont exactly see immediate frame drop when the GPU usage drops, but if something happens on my screen like a gunfight or loading parts of the map my FPS will plummet to sometimes 25.

       

      In general I feel my performance is lackluster - near matching my 660ti besides the hard frame drops. CSGO can sometimes go sub 100fps and H1Z1 on same settings as my 660ti can perform worse. If I benchmark on 3D Mark my GPU never drops below 98% usage and the setup scores around 4000 (healthy). Benchmarking on Wildlands I average around 98% GPU usage yet in game dont stay close to that, but the benchmarking results are pretty good.

       

      My PSU is pretty new, my CPU is pretty strong (even tried OC), and 16GB RAM has to be enough. The GPU and CPU temps never go above 70, and my CPU has healthy usage (70-99%). GPU fans work normally. I really need some help figuring out this card and sending it back and purchasing a 1060 if need be.

       

      Things ive tried:

       

      - Reseating the card

      - Using different HDMI port

      - Overclocking/Underclocking on CPU/GPU

      - Disabling power efficiency, setting high performance, maxing power output in Wattman

      - Disable ULPS

      - Updating motherboard BIOS

      - Fresh installing windows/cleaning drives (3 times)

      - Tried 10 different sets of drivers, ranging from very old to newest and default Windows ones (used DDU)

      - Vsync on and off/different graphical settings

      - CPU Core Unparking

      - Disabling ReLive and Xbox DVR

      - Killing processes of AMD in task manager

      - Maxing fan usage and temps to try to stop throttling

      - SSD and HDD (both functioning healthy)

      - Disabling all background processes

       

      My setup:

       

      ASUS RX 480 OC - Dual fans

      i5-4690k @ 4Ghz

      16GB DDR3 RAM

      Z97 PC Mate Motherboard

      EVGA Bronze 600W PSU

      NXZT S340 Case with 3 fans

      Samsung LED 1080p@60hz monitor

      2x 128GB SSD and 1 500GB HDD

       

      EDIT: Ended up getting exact replacement of the card and it looks like all is good - just a hardware issue (fingers crossed)
