I was already on high performance mode but had minimum processor speed set to 1%, I tried setting it to 100% and restarting and it made zero difference and didn't peg cores at max speed at all; most cores were still at 2.5GHz. I'm running the latest chipset drivers from AMD's website. I actually just tried comparing PBO vs 4.3GHz OC in Far Cry benchmark and there's no difference, the 4.3GHz oc had 1 more fps in average and maximum fps and the exact same minimum fps. By the way when I try PBO with Cinebench single core benchmark it never boosts over 4.1GHz. It fluctuates a ton and sits at 2.5GHz to 3.5GHz for most of the benchmark on 2 cores while the rest sleep. My Cinebench scores are within margin of error of the ones reviewers have gotten though, so it seems they must be experiencing the same behavior.

I tried that with the memory and it put my system into a bootloop. I had to clear the CMOS just to get POST. If you're running 8GB sticks they'd be single rank probably, I'm running 4x 16GB sticks which are dual rank so more taxing on the memory controller afaik. Threadripper has a stronger memory controller than regular Ryzen I believe. I'll try Windows Ryzen high performance mode.

Yes I get Ryzen will only boost if it needs to but what I'm saying is it does need to. It's painfully obvious these games are incredibly CPU bottlenecked so I don't know why on earth the CPU isn't boosting even just 2 cores. I mean the cores aren't even running at BASE frequency for the love of god. The reason I manually OC'd it was because with PBO and auto OC enabled and all power limits at max the processor would never go above 4.1GHz except for maybe the ocassional 4.4GHz for a few miliseconds while opening a browser tab or something else stupidly light. I do heavy video editing and 3D animation on top of gaming and manual OCing gave me a 11% improvement in Cinebench over PBO + Auto OC. Also in GamersNexus' review of the CPU their all core overclock did better in every game they tested, granted it varied between 1-10fps depending on the title. But it definitely wasn't worse in any games.

Hey guys so I've built a new computer system with a 3900x which I've OC'd to 4.3GHz all cores stable. However when playing games the cores all stay at super low clocks and my GPU usage gets massively bottlenecked at around 45%. In AIDA64, Blender, and Cinebench I see all 12 cores running at 4.3GHz just fine but in games I'm seeing them running at around 2.8-3.8GHz and performance definitely seems to be suffering greatly for it. Now I understand games don't utilize many cores but I'd expect at least the 2-4 cores that they do use to be running at higher clockspeeds. So far I've seen this behavior in Final Fantasy XV, Far Cry 5, and Red Dead Redemption; planning to test more, Red Dead Redemption does however have higher GPU usage than the other games. Here's the complete system specs: - 3900x 4.3GHz OC (overclocked using offsets, vcore fluctuates between about 1.24-1.26v depending on load, Ryzen master seems to incorrectly report this. LLC on medium - 360mm Custom water cooling loop for CPU - 3200MHz Corsair Vengeance LPX ram. Running at 3133MHz though as I have all four DIMMS filled and it wasn't stable at 3200MHz - Gigabyte x570 Aorus Master - RTX 2080Ti Strix OC (air cooled) This is a fresh install of Windows 10 and I'm running the latest BIOS and all motherboard drivers. I've attached a screenshot of my system's stats while playing Final Fantasy XV. By the way don't mind the 90° max tdie temperature in hwinfo, I was doing a torture test earlier before testing games and it spiked for a split second at some point during the test but was at ~83° for the rest of it. CPU temps during gaming are 55-60°
