4090 Problems
4090 Problems
I'm still figuring out where to start... This update from the 4080 to the 4090 was within the expected timeframe. So far, the system remains unstable. Games frequently freeze or stop unexpectedly—sometimes in minutes, other times after hours. The only changes I made were swapping to the 4090 model. On the 4080, I never experienced a crash with any game. Before installing the new driver, I ran the uninstaller in safe mode. I also can't play Cyberpunk at all; it crashes right after loading the logo or displays blue screens. All titles are now accessed through Steam. Shadow of the Tomb Raider is also problematic. After reinstalling the 4090, nothing improved. I checked for file corruption by running a data integrity scan and rolled back to an earlier driver version. That seemed to stabilize things temporarily after a DDU check. I kept the CPU at stock settings, used XMP profiles, cleared the DX cache, restarted, but results stayed the same. Tried repairing Windows via DISM, clearing CMOS, and even cleaning the GPU cache—still no success. The fan noise was odd, but it appeared to be a physical issue. I ordered a Gigabyte 4090 Gaming OC, which also failed; it had a dent, fans spun only at full speed, and the game kept crashing. Eventually, I went back to my original PC. Part 2 brought up a 4090 FE and led me to order another Gigabyte model. It still crashed after repeated attempts. Updated the BIOS to the latest version, turned off E-cores, cleared the DirectX cache, reset BIOS to defaults, and even ran Cinebench without issues. I’m stuck—three faulty units? The odds seem high. I’d like to try the card on a different machine, but I don’t know anyone with one. I no longer own the 4080, yet it never crashed under these conditions. I’ve used DISM online and Windows Memory Diagnostic without success. Drivers are often the culprit. Part 3 got another OC, but games still failed. I managed to run Time Spy once smoothly, scoring 30k—still low for a 4090. I attempted to lower the clock speeds by up to 300MHz and memory clocks, but crashes persisted in the second GPU test in Time Spy. I disabled ECC support, cleared the cache, reset BIOS, and even tried underclocking. Memtest86 completed 8 hours without errors, and Windows diagnostics showed no faults. I’m exhausted and questioning whether it’s worth continuing. If I had to guess, the chances of three unstable units are quite slim, but testing elsewhere would be wise. PS5 is still a tempting option.
It's typical for board stock to be high, yet Intel suggests a 253W power supply is ideal. Your current setup won't suffice for this level—now you might just get a better opportunity.
