yeh I have the latetst bios update, as fro backround apps im not sure, nothing is showing up as using too much cpu power in task manager, the problem from what ive seen is that in balanced mode my cpc wont downclock below 3.6 whereas in the power saver mode my cores will downclock to 2.2

With Zen i do not think it matters that it only uses a few percent. If i have it right the lower percent usage apps are what triggers the cores to wake up individually and draw 1.4V+. for example i just disabled icue and lost another 6 degrees in temperature but with it running i am only using a total cpu usage of 1.8%
Just did this, works wonders so far.
Thats good news, how is your performance and temps?
I notice the same with my 5900x. When I have just powered on the computer and logged in with it idling at the desktop I'm in the high 40c range, but if I shut down all the game launchers/stores that run on startup I drop down to high 30c range. The worst offender is epic game launcher. That gives the biggest drop in temps

Hey guys, first post here. But I was wondering, what are the expected core voltages for the 5950X when under heavy-load and using PBO and Curve Optimizer? I am seeing good performance here with cores overclocking to 4700mhz, but the vcore voltage gets boosted by quite a lot and HWINFO shows me it hits on average 1.462, but sometimes peaks at 1.500.
Everything I'm reading says this will shorten the life of the chip, is that true?

I uninstalled iCue, and my idles are now 31-35C with my single fan Noctua D15s, at 800RPM.
Seems that app, keeps the CPU active in the back.
Good thing is, my RGB profile on my ram Stuck, so even with the software removed the lighting hasnt changed.

It's not my thread so I am on holiday here.
Are you finding the 5950X to be a top performer?

I just received my 5900x and I had a 5800x for about a month. The 5800x worked well with +200 and curve optimizer. All cores could touch 5050 mhz. Single and multi-core boost would increase as well over stock. On my 5900x I get better single core performance at stock settings and when I mess around with curve optimizer I get better all-core benchmark scores but a bit lower single core. I tried between -10 and and -15 on my cores and played around with boost override between +100 and +200 and my cores don't want to boost as high for single core benchmarks. What am I doing wrong? This 5900x is a different animal from the 5800x and I was not expecting that.

You need to give the highest negative offset to your worst performing cores
Lol people buying 12 and 16 core cpus then complain when apps are using them and end up disabling apps to stop cpu usage.
Why bother with such a cpu if all people want to do is keep it idle?
I'm not a huge fan of iCue anyway, Link is decent imo although they're stopping support for it soon.
How does that even make sense though. Why would you want your worst core to take the biggest swing? Surely you want the best cores to have the largest swing (better cpus need less volts mentality), worst cores the smallest swing, then bring the whole lot up with +vcore offset within temp constraints / headroom. I need to go watch the amd vid again....
I'm sure they even said when using curve, start with your best cores...
If you leave pbo offset on +0, set all core to - 30, chances are you can boot and be stable, some chips might not be able to do this (maybe a weak core). When you start raising pbo offset, you'll only get so far then you'll loose stability or fail to boot resulting in the need to reduce neg offset on cores. This is because the neg offset swing is too much on your weaker cores. You'll end up reducing neg offset the more you add to pbo boost. Strongest cores will have the highest neg offset and weakest cores the lowest (or maybe even need to be positive if pbo offset is high). All of this ends up being a fine balancing act for getting the maximum perf on multi and single core along with package power and temp.
