Having used my new 5900X for a while, it's a significant improvement over my 3900x in VR - games which had poor performance like No Mans Sky and Fallout 4 VR now perform really well, hitting 90fps most of the time. I even find I can increase the Supersampling with little effect on the framerate.

I have tried the auto-curve optimiser's per core optimisation, but while the performance increase was significant, I get random reboots.
The optimiser put all cores at -22 which seems a bit suspicious that they're all set to the same value. I think I'll have to do some manual tweaking at some point.

I'd prefer if the temps were a little lower - it's going to 80 degrees regularly while gaming, but I understand these chips will boost as high as the thermal limit will allow. It's not reached 90 degrees at any point though, and there is the issue that my 3090 will be dumping quite a bit of heat into the case, which is not what you'll see when just doing CPU testing.

I did have a momentary twinge of regret that I didn't get a 3800X3D as that seems to have some huge advantages in some games, but the performance of the 5900X is definitely good enough for my use case.

That is a little warm, what are you using for cooling?

Try setting curve optimiser to -15 across the board, it's usually a good starting point.

Dark Rock Pro 4, on a default normal fan profile. Possibly I could get it cooler by changing the fan profile to be be more aggressive but I prefer a quiet PC.

Thanks for the tip on the curve optimiser values.

Just did a rather pointless 5900X to 5950X upgrade and have to start tweaking all over again. It's a slow process!

Try setting EDC to something like 150a, Google where that setting is for your mobo.

The EDC setting is pretty crucial with these chips, default is 200 amps on this board. It doesn't need to be anything like that, mine is set to 120 amps, Curve Optimiser is -30 on all cores. Changing EDC from 150 amps to 120 amps knocked 5C off my load temps and gave an extra 100 Mhz on all cores, boosting to 4.85-4.9 Ghz all core. All with less power used. Loads at about 72C on air cooling.

Mighty impressive chips these 5000 series, especially when you tune them up.

Is that when gaming or when using cinebench? Because I get 4.95 GHz when gaming and all I did was set all cores to -15. Not touched anything else as far as I recall.

Might give that a go and see what’s what. So far had no issues with -15 on all cores. Can’t be asked going doing an individual core by core just yet. Maybe do that at a later date when I get the itch.

Gaming, Cinebench they do 4.5 all core with temps in the mid 60's. This is a good balance, they can do over 5Ghz gaming when EDC is at 160 amps, but then temps go into the high 70's which is fine, but I like them to be a little bit cooler than that.

Just bought a 5900x. Was considering the 5800x3D but after looking into it, the 5900x was comparable performance wise for gaming at the resolution I do 1440p (UW) and was cheaper. I'll be running it in a SFF build so keeping it cool while minimising performance loss will be the priorities.

Can anyone give me some advice on where to start with PBO/CO, etc ?

I felt the same way (for my needs) when I upgraded from a 5800X to 5900X last summer! Thankfully I sold my 5800X for only £50 less than I paid for it. Anyway, I'm very happy with the 5900X for now.
