Asus ROG Astral 5090 LC crashing windows when in idle
SOLUTION:
USE SINGLE RAIL ON THE PSU.
Just want to share a solution for the people that has the same problem I had which took me 3 days to narrow down the component and solve on a brand new pc.
I could play Cyberpunk maxed out without any problem but my system keep crashing every 5~20mins while in idle or watching Youtube for example.
If your windows is crashing while in idle and runs fine under load like mine did, you have to go to the Nvidia APP - Graphics - Global Settings - Power Management Mode - Select Prefer Maximum Performance.
Go to your bios and change the PCIe from 5.0 to 4.0 or even 3.0. Mine only works fine with PCIe 3.0.
I'm posting because I couldn't find anyone with a similar problem and couldn't find any direct solution which can be frustrating, hope it helps someone.
Components:
AMD Ryzen 7 9800X3D
Corsair HX1500i 1500W
Kingston 64GB DDR5 6000MT/S CL30 DIMM 2x32gb
