Prime 95 performance issues
Prime 95 performance issues
Lately I've gotten crashes and black screens, so I tried to get to bottom of it by running Prime95. And it works fine (Blend mode) for about half an hour. After that fails always either thread 3 or 4 or both. So my CPU might be defective? I've tried several RAM sticks and lowered OC to default speeds but yet 3. or 4. thread fail. I'm guessing theres nothing else to do than buy a second CPU to test? My CPU specs are in my profile, but motherboard is GA-Z270X-Gaming K5 and CPU 6700K. CPU delidded and at 4,6GHz (1,3v) Also, Small FFTs runs fine. Maybe memory controller faulty or overheating? Though temperatures of CPU under load are below 80C. Haven't run Memtest86 much longer than 30 minutes, as usually memtest reacts faster to RAM errors than Prime95. And memtest86 does not find any errors. --- But maybe VRM MOS gets too hot?
Test the GPU using GPUPI 3.3.3. Inform me if any issues arise during testing. Download link: https://www.overclockers.at/news/gpupi-i...ort-thread
GPUPI runs smoothly. The 1B model is also showing signs of the VRM getting warmer gradually. Prime 95 errors typically don<|pad|>, they appear after roughly half an hour.
You shouldn't adjust those settings that way... The default should be 32B, which is what you need. 1B distributes the workload between GPU and CPU, making it less demanding.
NVLDDMKM.SYS is the Nvidia driver, possibly indicating a graphics driver issue or even hardware problems. I hope it's just the driver. Try removing the Nvidia driver using DDU and then install the latest one.
It looks like the CPU might have a problem, especially with threads 3 and 4. It seems similar to the issue with one core having hyperthreading. I’m hoping it can be fixed or repaired.
It's designed for 10-minute extreme temperature tests and a fast stability check. The blend is used for longer hour-long stability assessments, covering the entire CPU, power delivery, IMC, and RAM.
