Question Curve Optimizer taking 11 hours ?

So, i was trying to get a curve optimize going and every guide says it takes a few hours, but this does not look like a few hours to me?

What CPU are you running? A 16 core CPU will take a lot longer than a 6 core CPU because it runs a complete test on each core, a single core at a time. You decrement the offset for a failed core, as many times as it needs until it finds one that doesn't cause errors during the tests.

It has to run a single core at a time to make sure it's boosting to the maximum boost clock possible during the test workload. And once you finds offsets for each core that don't fail you have to run it for at least three complete passes for confidence. And repeat that using a different testing program (Prime95, y-Cruncher are a couple provided) for highest confidence.

It is configurable so you could shorten the tests, but with somewhat lower confidence in the results. That may be OK if this is just a gaming machine.

But while it may be very time consuming to properly test custom CO offsets, when you consider that you can potentially lose days of intensive processing work should it crash in the middle of a task it's worth the time to do this for a production machine. Either that, or just accept the slightly lower performance that comes with leaving the manufacturing margins in place, as AMD designed it.

Thank you for your reply.
I uninstalled Ryzen Master and cleared the CMOS to let the CPU run at default settings.

Right now my system has a random stutter i cannot even localize and this Curve Optimizer and Overclock won't be worth time if i cannot get rid of that first i have a stable system.

I had similar random stutters. Tried everything....until I realized it went away when using an HDMI cable and connections to my monitor. It's 144hz refresh monitor but only through the DisplayPort connectors; the HDMI connectors support only 60, 72 or 120hz.

But I wonder if it's the monitor causing it (somehow), bad display port cable or the GPU. At any rate, I'm happy with 72hz and never saw the benefit of 144hz anyway, so I am content and not pursuing it further..

i've already tried with an HDMI cable.

Stutter persist.

My FreeSync range is 40 to 75, i don't want more than that, just stable frames.
 
CO is useful only to control temperatures thru voltage regulation and there are other ways to do it. If your cooling and settings are such that Tjmax is not reached, it's not of any use. It's even less useful to do it by Core instead of all cores or per CCD. That is for very fine tuning only. Even after automatic tuning you would have to test it multiple times and maybe correct it, it's never 100% sure.
Just go to BIOS, choose per CCD or all core, put a value of -10 and try like that. increase if stable and check again.
The best way to get best from Ryzen is to cool it at least enough to stay bellow Tjmax which is between 90 and 95c. depending on model. Under those temps can only make you feel better
