Something else to consider would be to check your motherboard's default settings. I'm not familiar with Gigabyte's AMD bios setups, but my MSI B550 defaulted to having their auto-OC enabled (MSI Game Boost) which works, but applies higher Vcore than necessary. I wouldn't be surprised if Gigabyte has a similar feature.

OC'ing on this platform is a whole new and different beast than what I was used to (coming from Intel) in that there's a ton of adjustments going on in the background WRT power usage which throws a wrench into the old idea of let's adjust cpu freq + vcore to come up with a decent OC.... higher cpu freqs / boost don't always result in better performance.

I ultimately decided on turning off all of the automatic OC options (AMD PBO) and just let the processor do it's own magic via boost clocks. I ended up with performance within 3% of my highest stable OC for the great majority of tasks and 8% of a full multithread load. This allowed me to set a negative vcore offset (-.0875V IIRC) to keep temps down even with the stock cooler.

Everybody's chip is going to be slightly different though so YMMV.

5950's have a lot of cores. 50c seems high, but if your full load is only high 60's low 70's I wouldnt worry too much about it. Also I agree with @sswilson that there is probably some default junk going on in your motherboard bios that could be raising temps, and preventing cores/ccx's from sleeping.

Having sunk a lot of time in to my 3900x, and my 5600x trying to eek out performance, I can say this is also what I've settled on. PBO2 is great, and I expect it to get even better once Agesa 1.1.0.0 is dialled in. I just wish I could get the hours back figuring out that I could of got 95% of the overclock with 0% of the work...

Thanks and here's a quick response. I'll check those things later....
Room temp is 20/21c tops. I seem to recall in Bios that a lot of parameters were on AUTO!
Perhaps I'm after the zero percent work while you all give me the info....hehe
Joking aside, thanks again!

Glad you got the monster up and running! My 5950x was wrecked in shipping and landed with a ton of bent pins. I'm gonna use you as a baseline if they can un-bend the pins and sell it back to me. I have the exact same board / RAM (assuming you got the 16/16/16/36 stuff in 2x16GB format). Enjoy that new 16 core space heater, and Merry Christmas Geezer!

That's terrible! Shockly sad....Crickey!
My CPU box had a tiny ding in it but contents were well and good. I'd hope you could score a brand new unit and not a refurbished one. Cool you have the same gear and I'd be happy to share notes with you

Stay well.....CHEERS

Merry Merry.

So regarding my temperature concerns when at idle........50c in Windows AMD Ryzen Balanced .
I switched to windows power savings from balanced and I'm in shock!
Ryzen Master shows CPU idle temp at steady 28ish as does Aida 64, wow!
I'm looking into how this might affect performance. I would think while gaming performance won't take a hit or will it?

I have to share a t-shirt my wife gave me today

The only way to know for sure is to do the benchmarks, but I suspect that while there would probably be an FPS penalty it'd be minimal. From my (albeit relatively limited) time playing with Ryzen I'm of the impression that letting the magic sauce behind boost clocks do their thing manages to squeeze out a high percentage of potential performance on everything but heavily multi-thread loads (like content creation / rendering).

I'm a bit confused though.... did you switch your profile "from" balanced or "to" balanced? I just checked and I'm still on "best performance" without silly high temps at idle. Is it possible that you had done a fresh windows install and it was still doing it's new install file indexing which caused it to be at higher idle loads than normal?

edit: Upon closer inspection, I'm not sure which power profile has precedence. I had "max performance" selected on the settings slider, but the advanced settings (control panel) was set to AMD Ryzen Balanced.

 

[GeezerGamer]

Well I'll fiddle more later but I noticed in Task Manager that CPU speed gets dropped down to 2.2 GHz in Power saver Mode were as it's 4.4 GHz when set to AMD Ryzen Balanced!

Edit....yeah so after a little Borderlands 3 action in Power Saving mode that's clearly a no go as CPU stays at 2.2 GHz and doesn't automatically kick up to playable speeds!

 

[Sagath]

From everything I've read zen should be on balanced power profile for optimal performance.

I believe there is a post/tweet out by someone from AMD about it. I cannot find it right now though.
