You mentioned during BIOS setup for XMP that you might have saved the default settings instead of the adjusted ones. The default settings act like a factory reset, lowering speeds to protect components, but it's unlikely your clocks would drop that low while gaming—just at idle. It could also be a coincidence that your MB settings required a reboot. Have you checked for updates to your MB chipset drivers and BIOS? Since your CPU is a newer high-end model, it’s worth confirming compatibility with the current BIOS version.
I attempted several solutions. I restored My bios to factory defaults, benchmarked, but no improvement. Then I used a 4.65 OC with correct RAM settings and timings/voltage still didn’t work. A GPU vbios update was applied afterward, yet the issue persisted. I’m going to check for any available bios updates right now, in case one is needed soon.
Generally I don't bother with BIOS updates unless I'm having a problem that can't be fixed otherwise. Since you're having strange problems and have a new model CPU though, I'd say it's advisable, especially If you've not even checked or read up on any possible BIOS updates. I DO advise reading what they're for before installing them though.
Well, here we are once more... after checking, I was roughly three bios versions behind (just like you, I don’t update bios often).
I updated the bios and adjusted the settings to my original OC configuration as usual, but still stuck at a 420mhz GPU clock.
I also noticed that when this problem occurs, the EVGA PX1 displays zero values—zero clock, zero memory clock, zero voltage.
When everything was functioning properly, the clock speeds would fluctuate and change based on the application being used.
What kind of MoBo do you have? Often the software for managing devices such as MSI dragon center or now Control center can have problems with profiles, leading to incorrect voltage and clock settings. This might result in issues like clock limits being enforced or general malfunctions. It’s frustrating because sometimes it sets voltages higher than intended on certain components. While improvements have been made recently, checking it out is still a good idea if you’re experiencing difficulties. Another helpful tip is to open the NVIDIA control panel, go to help, and select debug mode—it will set the GPU to its base clock and disable any imposed limits, allowing you to identify the problem more precisely.
I have an Asus Crosshair VIII Hero. It's disappointing to say, but after it worked fine last night... this morning it's still struggling, with FPS dropping to the low 10s and the GPU clock stuck at 420mhz.... 😡
I successfully retrieved my standard backplate to install the GPU directly into MOBO without needing the vertical GPU extension. After a brief boot, the screen briefly stayed black with a faint pixel line resembling a tear, but it loaded normally in Windows and is functioning properly now. I ordered a replacement extension just in case the previous one was faulty. The extension currently in use is the one that comes with the Lian Li 011 Vertical mount backplate for PCIe 4.0. I’m pleased to say that after rebooting, everything appears fine. Previously, after a reboot, it would revert to a poor performance mode. I’ll update again once I install the new PCIe 4.0 extension and vertical mount the GPU. So far, it seems the Lian Li PCIe 4.0 extension might be the issue.
As discussed before, adding a long PCI-e vertical mount adapter extension isn't ideal because it can raise latency and often causes inconsistent performance. I'm confused about why we keep using that configuration instead of just mounting it horizontally. You mentioned it's related to your specific setup, but a case that is flexible should handle different GPU positions smoothly. I usually prefer a horizontally mounted GPU—it prevents dust from clogging the fans and heatsink and helps pull in cooler air from lower areas. Your decision seems risky; maybe try something else this time.
The vertical GPU configuration was more closely aligned with the custom loop I’m planning to implement soon. I’m open to adjusting it slightly and installing the GPU in the conventional manner. I recently received the new PCIe 4.0 extension and reattached the GPU vertically using the updated extension, then restarted the system. Everything worked smoothly, so I suspect a faulty extension could be the cause. I ran the Heaven benchmark without any problems. I’ll monitor it throughout the day; if everything remains stable, we can pinpoint the issue. If the problem recurs as you suggested, I’ll revert to the traditional mounting and update my loop design. I’m looking forward to a successful next release.
