Rx480 overclock crash
Rx480 overclock crash
I recently attempted to overclock my RX 480 with 8GB RAM and have encountered problems since the moment I powered it on during a test. I’m unsure what I was doing, so I watched a video and followed the settings from Wattman. The memory was set to 2250MHz with a power limit of 20%, temperature max at 85°C with a target of 80°C, and the fan speed was configured to 5200 RPM with states 5, 6, and 7 at 1330MHz and voltage control at 1150. After making these adjustments and running a test using "gpu-z" which caused an instant white screen crash, I became very concerned and turned off my computer. Since then, every time I boot up, the fans inside my PC become extremely loud for a few seconds before returning to normal. I checked Wattman right after and everything was restored to default settings, even after resetting. However, my PC still shuts down violently with loud fan noises during startup, especially after playing games for about an hour—possibly the third game I played since the display went out, requiring a hard reset. I’m wondering if anyone can explain what’s happening, whether the noise is normal or related to the overclocking, and how to fix these issues or if my GPU is now causing the display to flicker during games.
Here are my specifications:
I3 6100 3.7ghz
8GB DDR4 2133
750W power supply
MSI H110M motherboard
Reduce the target fan RPM because that’s likely what’s causing the noise.
I’m not very familiar with these power modes since I still have a 7970, which only offers three of them.
Your memory frequency was too high, which is why you saw the instant white screen. If I were you, I’d stick with the 1330Mhz for the GPU and keep the VRAM frequency unchanged. That’s not the main bottleneck.
PhysX_HW suggests reducing the target fan RPM because that’s likely causing the noise. It mentions a lack of familiarity with various power states, noting the user still has a 7970 with only three options. The high memory frequency was the real issue, leading to the instant white screen; for someone in the same situation, keeping the GPU at 1330Mhz and leaving VRAM frequency unchanged would be better.
I believe sending it back with a warranty might be the best option since the display shutting off after an hour of gaming bothers me. I’d rather get a new GPU than face this problem, and they said they would handle it. I might just sell it and upgrade to something better. Regarding the RX 480 S XT3 at 1330 MHz — is that an improvement? Or should I move up to the next level? I’m not planning to overclock this one again because I’m unsure what I’m doing, lol. I’m aiming for a budget upgrade around 300, but I don’t want to spend much more than I did on this one (around $280 at Best Buy).
