Omen 30L Crashes in certain games

[Pløf]

Indeed, it's a peculiar issue.

I attempted troubleshooting by removing one RAM block and encountered the same problem. Subsequently, I tried the same with the other RAM block, only to face the same issue again. Thus, I can confidently conclude that the RAM is not the culprit. I was playing the game in offline mode, so it shouldn't be a networking issue.

Thank you immensely for your assistance. At this point, I believe the problem is likely to be either the motherboard or the GPU, as these are the only two components I haven't yet swapped out.

Hi @Pløf 

My pleasure.

Don't forget the power supply. I would start with the PSU since it is the less expensive component.

Exciting update! I experimented with MSI Afterburner by adjusting the Power Limit. Initially, I set it to 60%, and during this period, everything ran smoothly. However, when I increased the Power Limit back to 100%, the system unexpectedly shut down. This leads me to suspect that my current 750W PSU might be inadequate, possibly due to occasional power spikes exceeding its capacity. Could you recommend a reliable power supply unit? I'm particularly interested in options around 1000W that would comfortably fit within a 30L case. Your suggestions would be greatly appreciated!

Hi @Pløf 

Good idea using Afterburner to adjust power limits. Nvidia recommends a minimum 750 watt PSU for the 3080. Your HP provided PSU may have a problem. Or the 3080 has a problem. This is still indeterminate.

I think your PC has a Cooler Master ATX PSU.

Check the dimensions (L, W, H) of the HP installed PSU. Then find a higher wattage PSU with the same dimensions.

I have used Corsair, EVGA, and Seasonic power supplies with great success.

You really should run your 3080 in a different and compatible PC or run a different (equivalent) graphics card in your PC to determine if the PSU or the 3080 is the problem.

I have ultimately resolved the issue I was facing.

The initial step I took was to replace the thermal paste on the GPU, but this proved to be a temporary fix as the PC soon crashed again.

Upon closer inspection, I noticed that the PSU cable connecting to the GPU was a split type, with an 8-pin connector branching into two 6-pin connectors, both of which were required to power the GPU. This led me to suspect that the single cable might not be delivering sufficient voltage to the GPU. To address this, I connected an additional 8-pin cable to the PSU and used one 6-pin connector from each of the two cables to plug into the GPU. To my relief, this completely resolved the issue, and there have been no further crashes.

For those experiencing similar problems, consider upgrading to a higher wattage PSU or simply adding an extra cable as I did.

Thank you Bill_To for your assistance over these past few days; it has been greatly appreciated.

Hi @Pløf 

My pleasure.

Good troubleshooting.

I am in disbelief HP would ship the PC with only one, 150 watt, PCIe power cable connected to the graphics card. The 3080 has a 320 watt TDP, HP was only providing 225 watts to the card.

This will cause system instability in GPU intensive games.

Anyway, it appears to have been a power delivery problem after all. Never expected HP would under power the 3080.
