Since I sold my 6900xt for having awful coil whine with the waterblock installed, I migrated my old 1080ti into the loop with the 5950x.
I figured it should be about as fast or maybe even quicker due to the 5950x's superior memory speed, clocks, and IPC vs. the old 5960x.
3dmark shows a different story, though - The GPU only sits around 94-97% utilization (always 99-100% on the old 5960x box) and scores 5-6% lower at the same GPU clocks.
For reference, with the 6900XT installed with the same CPU and memory config on the 5950x, it would hit 99-100% utilization in 3dmark.
I checked the pci-e connection and it's getting a full 16x 3.0 connection. Is there any configuration change or troubleshooting steps I can try to get the card to actually hit 99-100% utilization? It seems so strange since the system was clearly capable of driving a card ~2x as fast at 100%, that it cannot drive the 1080ti at 100%.
On a side note, the 980ti I had in this same rig before the 1080ti would hit 99-100% utiliation as well. Just the 1080ti acting up for some reason I cannot figure out!
5950x stock boost (dynamic all core overclock at 4.6 ghz when heavily loaded)

2x16gb dual rank b-die at 3800CL14 1:1
Latest driver 461.40, clean install done since 980ti swap.
