Freezing occurs during gameplay or high GPU usage on a 3090 Ti system.
PC specifications: Windows 11 Pro, 64-bit CPU i9 12900k, RAM 64GB Corsair Vengeance RGB Pro (XMP supported), SSD 980 Pro 1TB, Power supply beQuiet Dark Power 12 1000W, GPU Gigabyte Aorus 2080ti Waterforce Extreme or Zotac RTX 3090 Ti with AMP Custom loop and dual 280mm radiators. Previously tested new GPU in air before installing waterblock – a positive delay.
Community feedback: Many mention similar freezing issues after upgrading to the RTX 3090 Ti, switching PSU, and adjusting power settings. Some tried enabling overclocking on a single rail, disabling OC mode, or mixing rails. One user reported persistent PCIe Root Port errors but no longer constant.
Current troubleshooting: Running with 2080ti after heavy load and OC up to 265W without freezing. Still seeing a recurring error in Event Viewer about PCIe Root Port, though it’s less frequent now. No alternative PSU available for testing. Uncertain whether the problem lies with the power supply or the GPU.
Consider evaluating both PCIE 3.0 and 4.0 modes to determine freezing behavior with each.
I checked online sources and found that the 3090ti should work with 3.0. My current PCI riser cable is only 3.0, but I’m wondering if the 2080ti also supports 3.0 without problems. I haven’t changed the BIOS settings or tried other GPU bios, though I’ll give it a try. It’s frustrating because of the custom loop, making card swaps difficult.
Yes, 30 series GPUs are compatible with PCIe 3.0. Are you confirming you're using a 3.0 riser with the 3090 Ti? Have you tested without it?
I haven't tested it without the riser—it was just an idea. Because the custom loop leaves no space for mounting the large 3090ti card, even in my Phanteks Enthoo Evolv, without some major disassembly. I'm considering moving away from a custom loop, though it's ideal for temperatures; it becomes too complicated for troubleshooting and general upgrades.
I suspect the riser might be the problem. Many users have faced challenges with 3.0 risers paired with 4.0 GPUs. Most have resolved it by setting the slot to run at 3.0 instead of 4.0 in the BIOS. Although the order seems confusing (4.0 > 3.0 > 4.0), I recall it should be 3.0 > 3.0 > 4.0. It’s simple to verify yourself. Give it a shot!
You're unsure about the correct setting since you have a CPU and PCIe speed option, but your 2080ti isn't appearing in Device Manager. The issue might be with the PCIe 4.0 riser cable you plan to install.
