Help with Curve Optimiser

SO I had my 5900x at 4.7 all core manual overclock but it was getting hot under heavy work loads. I've now changed it to PBO CO with -30 and all is good. Single core R23 score is 1624 and she boosts to 4850MHz I think but Multicore is low 21000 and it's only boosting to 4400MHz while pulling under 1.2v.

How can I get my muilticore boost up without silly heat?

You could try increasing the PBO limits to allow for more power but as for increasing multicore without adding extra heat then that is pretty much impossible as a higher boost will require more power and produce extra heat.

I've got the limits disabled.

have you tried adjusting the scaler?

 

[Klunt Bumskrint]

Yeah, I tried 2x then 4x it just seemed to lower my boost clock

 

[Joxeon]

Then your probably already at the limits of what the CPU can boost to all cores as the higher core count CPUs generally have a lower all core boost.

booooo

Thing is at the moment during cinebench it's running at about 64 degrees so there is more headroom, maybe I need a better manual overclock. It's just games seem to prefer the single core speeds

There is a guy on here called the asgard who seems to know his stuff, search for a thread called 5000 series undervolting, sure he'll be about to help you.
I found in my very limited experience that undervolting increased multicore but decreased single core, but that was just me with my limited ability, others may have different results.

Unless your gaming at 1080p I doubt it will matter.

On my 5950X I have the scalar set to auto, I used to set it to 4x but I think it was actually costing me performance. I've got a per core undervolt going, I do set a temp limit of 85c.
On my AsRock board I set my PBO to manual as otherwise it won't boost above 4.2GHz. I then have both the TDC and EDC set 160 and the power limit at 300W. During winter I get a boost to about 4.65GHz and my R20 score goes from about 10300 stock to 11500. It does sit at 85c when encoding though but with a temp threshold I know it won't cook itself in the Aussie summer.
