Ryzen 5900 advice

Hi, would appreciate any owners here Shari g their tips / views on tweaks and settings for getting the best from this CPU for DCS…….Not interested in unstable crazy overclocks, Just a reliable boost.

thanks!

Hi,

I have a slightly slower CPU but had the same idea. I would have a look into YT and search for videos in regards to undervolting. So with lower voltage you run the same speed. This ends up in lower temps and respectively the boost can be slightly higher.

Here is one example:

Undervolting with PBO2

I hope this comes close to what you were looking for.

Xoxen out.

For getting the best single core boost without a ton of nitty gritty fine tuning, just use the Curve Optimizer and give it a negative offset.

Start with 10 for every core and use OCCT for stability testing. It will tell you which core can't keep up. Then raise the negative offset for every core by two and repeat until you eventually find a core that can't keep up. Reduce the offset for this core by two and continue the process with the rest. If you're lucky you may end up with -30 (maximum) on all cores, but that is unlikely. (btw. your best cores will probably end up with the smallest offset, because they are already pretty efficient)

If that is too much work, you can use the offset as one global parameter for all cores. Or you could just do it per CCD.

But I have to admit, that just going with PBO, will give you probably 90% of the gains already. Unless you really have fun when messing with this stuff, the results probably aren't worth the hassle.

Edit: Typos

Another thing. With good cooling my 5900X reliable boosts to 4900 MHz on stock settings (PBO), occasionally I will see 4950. Best I ever reached with all kinds of fiddling around was 5050. You won't notice the difference in DCS at all.

You can easily gain a significant uplift for true multicore applications like Cinebench, but since you are only interested in the max single core boost for DCS, PBO already does the Job for you.

Thank you

I don't touch mine and it gives more than I need for DCS.
