Question No Difference After Apu OC
Question No Difference After Apu OC
I have an R5 2400g
I was attempting to OC the GPU
Starting at 1240MHz, then increasing to 1340MHz
Testing FPS in Furmark
Both measurements from base clock and OC are identical (1494 points at 25FPS average)
I adjusted it to 1500MHz in Ryzen Master with 1.2V, but the test didn’t show any change. After restarting, it returned to the base speed of 1240MHz. However, when I set it to 1500MHz in BIOS, the PC crashed.
My motherboard is an MSI B450 Pro VDH Plus. What are your thoughts?
I also came across a discussion online. When we increased the frequencies of the integrated graphics core on both APUs, we noticed a strange behavior or 'black hole' between 1350 and 1500 MHz. No matter the settings, the system showed clear problems. Even when it would boot at those speeds, overclocking combined with drivers led to random restarts of the test system, frequent crashes during games, and Windows Crash Reporter flagging a 'Video_TDR_Failure' for the atikmpag.sys process. This kind of error usually points to a faulty or corrupt graphics driver, but in this case, it affected multiple systems with different motherboards and operating systems using AMD's Adrenalin Edition 18.5.1 WHQL drivers (the latest available at the time). The problem persisted regardless of the GPU driver or BIOS version tested.
However, at 1500 MHz the issue disappeared. Our experience isn’t unusual—other experts have faced similar challenges. We’ve contacted AMD about this and will provide an update once we receive a response.
