Unusual actions from the GPU and frequent crashes.
Unusual actions from the GPU and frequent crashes.
Are you employing any specialized cables for the PSU, riser wires, extension leads, or connections from another (or outdated) power supply? The Pure Power 12M guide mentions this. Have you thought about distributing the load across the 12V rails? Since your MBO (CPU) is on V1, did you link the GPU to V2? Perhaps one cable from the GPU to V2 and another from V1?
Hey, thanks for your reply, I had considered the possibility of the PSU being the culprit. However, a couple of things make me think otherwise. Firstly, the power levels we're discussing don't seem high enough to cause issues. Secondly, I'd expect to hear the internal relay of the PSU triggering or experience more significant system failures if that were the case. To put it in perspective, the GPU at its peak consumes around 230W, and the CPU uses about 80W. Even considering sudden power spikes, it's unlikely they'd max out the PSU. Moreover, these crashes occur just as frequently during idle times as they do under load. I'm not using any supplementary cables. The GPU is directly inserted into the motherboard's PCI 16x Gen5 slot, and I've stuck with the original PSU cables. Here's a rundown of my current connections: The primary motherboard connector is attached directly to the motherboard. The GPU is connected via two distinct cables linked to the 12v1 and 12v2 rails. The additional 4-pin and 8-pin CPU power connectors at the top of the motherboard are each connected to the P8 PSU 12v2 connectors using separate cables.
Great suggestion, no tests yet. I'll review and reply later. The only concern is using the pigtail connection, though I hope the cable can manage it.
Yes, you can verify the GPU performance on another machine or with a different power supply unit.
I think I need to figure out a solution if I want certainty. I can try it on the old PC with an i7-4790, which might cause a big slowdown but if it persists, the issue should be with the GPU.
I finally got around to testing; the past week was quite busy for me. Here's what I observed: When testing on a different computer, the direct GPU test didn't appear to throttle or bottleneck the performance. It reached 100% in all tasks. However, I did face some peculiar issues. For instance, the graphics card wouldn't initiate until after I restarted the computer. It didn't crash, though. This is the sequence of events: Cold boot: The GPU isn't detected and doesn't even initiate the fans, which typically turn on during a boot. Upon restart: Everything is in order. The GPU functions properly, and both stress testing and gaming don't cause it to shut down at least for the short testing time. Now, here's where it gets odd. Once I reinstalled it into my primary computer, the performance seems to be somewhat stable. There was one crash during a highly intensive task, but there haven't been any random shutdowns. Is it possible that GPUs have a 'burn-in' period similar to audio amplifiers that I might not be aware of? P.S. As I mentioned earlier, the older PC uses an i7 4750. The power supply unit is a single rail Be Quiet! 600W, which should adequately support the demand. The RAM is DDR3; I haven't checked its exact specifications, but I deem it irrelevant for this context. P.P.S. It started randomly crashing again on both machines. I am gonna call it its some capacitor somewhere going wild and taking some time to charge. I guess I`ll have to RMA it again.
