So, I've upgraded to the 9850X3D from the 7800X3D a few days ago and I decided to restabilize my timings, before doing any stress tests with PBO settings. I'm now able to tighten tRCDWR to 16 now since I was unable to on the 7800X3D. I'm also looking to match the PHYRDL, but I wanted to stabilize this first so I can eliminate some guess work along the way. I've found I just needed to raise the VDDQ and VDDIO to 1.46V to help stabilize GDM disabled with this chip. I had to fix a few issues earlier when after installing this CPU, my Bios was setting the DRAMDqDs to 48 instead of 34 Ohms (This led to a lot of training errors), so I basically lowered it to 34 Ohms and that fixed the issue. I will be stabilizing 2200FCLK later on. (PBO was set to auto for all screenshots).
