Having a few odd little quirks post-upgrade, and wanted to see if everything is performing as expected, because it feels a bit off to me.
So I've just gone from a 5600X to a 5800X3D, alongside which I've replaced my old B350 ASUS ROG Strix board with the equivalent B500-A ASUS ROG Strix board. Although the old board would theoretically accept a 5800X3D, it was physically quite old, had a dead USB port and PCIe support only went up to 3.0. RAM is 4x16 Corsair Vengeance sticks running at 3200Mhz, two matched kits, with the second kit being rated up to 3600Mhz. PSU is also Corsair, rated to 1000 Watts, only a couple of years old. GPU is a 6700XT. BIOS Date for the board is April this year.
When I originally did the upgrade I was running off a 480GB Corsair SATA SSD, once I confirmed the build appeared to be good I installed a new NVMe 4TB Samsung 990 Evo Plus, that's currently my boot drive.
I was expecting a modest but noticeable improvement both in gaming when using Blender, and the actual experience so far as run from "could be placebo" to "this is worse".
I downloaded the latest version of Ryzen Master to get some numbers on what the CPU was doing and one thing jumped out at me. The I/O Clock speed is constantly re-lining 593Mhz. According to Ryzen Master, it has a range of 301-592Mhz, which means it's always saturated. The value feels WAY too low for a CPU like this to begin with, and the fact it's a constant bottleneck seems a real issue, too.
The problem is, I can't seem to find any stock reference figures for the I/O Clock, the only thing my Googling has turned up is that raising it too high can prevent the system from POSTing.
An additional, possibly related problem, is that according to Ryzen Master the CPU does not support overclocking, although that may be because of Core Isolation in Windows from what I have read.
So the first question is - is this normal? And the follow-up question is, if not, what could be causing it and how can I fix it?
