AM5 Overclocking

jellybeard999 · 9 Feb 2023 at 23:19

I tried posting this in the AM5 thread, but it got lost in the discussion.

Can anyone advise / provide a link to a simple guide to AM5 overlocking?

I've a 7600, with a Noctua D15S and 6000mhz RAM in a MSI B65PRO B650M-A WIFI.

I'm not wanting to fiddle around for the last few mhz, just increase the voltage/temperature ceiling a bit and let the boost do its thing.

I've set my RAM to EXPO timings and enabled PBO. As it stands my CPU boosts to around 5.0-5.1 at 1.26v according to CPUZ when running Cinebench.

Any tips/pointers/suggestions appreciated.

the 7600 is just a 7600X with a lower power limit. if you look up the stock settings for a 7600X, you can get an idea of how high you can go.

I've changed the enabled and disabled PBO. This seems to make little difference and boosts to 5150 either way.
I've changed the PBO to the maximum +200mhz and this takes me to 5350 boost.
I've changed the PBO to manual and upped the wattage settings (PPT, EDC, and TDC) and this doesn't seem to make any difference.

Am I going about this the right way :confused:

amd have stopped the none x chips boosting as high on the latest bios's you can still manually overclock higher, or maybe try an older bios.

Well that's dirty, having it there on day one then taking it away. Surprised they can get away with that :eek:

nope that what PBO dose, its poo....
just do a manual OC

Does that change clock speeds permanently? Or does it still boost? i.e. would I be sitting at 5.4ghz or whatever on the desktop?

I think I'll have to look into it more. I've only really played with the PBO function and I think you're right!

It still boosts over the advertised speeds by 50mhz, so yes they can get away with it.

it would still clock down, and would generally run cooler. PBO tends to just dump power into the CPU to boos.
it most cases a fixed clock is also faster

this is all core not just BPO busting one or two core's to a max.
my 5600 will run at 4.75Ghz or PBO at 4.6Ghz and 8c more
my 3600 would run at 4.475Ghx or BPO at 4.35Ghz and again hotter
i got better temps and scores in ever bench i run, including games.
