So is the Ryzen 3900X as good as expected?

I must be one of the lucky few, I'm getting just over the advertised boost clock, but my chip seems to idle at 1.45 to 1.48vcore even when running less than 500mhz on the chips that are active (with 8 having a little sleep). Not sure if that's something to worry about, but that's basically the idle voltage, it actually goes down when I'm gaming! Seems to be ever since I put AMD chipset drivers on and used the Ryzen power plan, thinking of changing it to the base Winders ones as it was significantly lower.

dont need to catch up. said cpus dont run at said speeds. its that simple. they will be fined for this. just like intel and amd do all the time. over past gen cpus.

Unless someone can prove AMD was negligent then there will be no fines. AMD will be given time to get the software right as there is ample evidence out there to show that software is the culprit.

last gen cpus have nothing to do with this, you cant sue for a bug if theirs no negligence. speaking as a software development manager with thousands of hours dealing with bugs and hundreds of thousands of hours testing, do you think anybody would make software if this was the case?
you cant sue security software providers for missing a virus for instance and someone stealing your data as a result, what in the world makes you think you can sue AMD for this, considering they have owned up to the mistake. :D AMD and Intel may both get sued every now and again for some daft claims etc, but how many times do you think the case is successful? normally its quicker, cheaper and easier to just settle and move on (that should tell you everything you need to know).

before AMD fessed up to the bug, you may have had a leg to stand on, but you now don't.
 
That depends on what type of cooler you use and your case. I currently have a D15 on my 3900x and my idle temps are around 34-45 C and my gaming temps range 50-65 C. This seems to be seen as good temps.

How are the 3900x temps?

Intel pointing the finger at AMD seems a bit rich and desperate imo. Not a good move at all.

I Have a H100i v.2 In Push/Pull on my 3900x. Idle temps are around 29c -36c, Gaming seems to be around 50-60c.

Happy With Temps, not as hot running as people are making out.

Same cooler, but I idle slightly higher at around 33c-42c.

There’s so many variables though, case airflow, ambient temp, thermal paste. It’s a hard comparison to make.

Loads of variables, so results are "okay" to "very hot" lol. Mine is (roughly) as follows, with a Corsair H110i with fans at around 1200rpm and using Kryonaut TIM. Monitored with HWiNFO64.

Idle -- high 30's low 40's
Gaming -- high 60's to low 70's (game dependant)
CB20 benching -- 75c

edit: Lowest here is 32c actually, didn't notice :)

My temps are 50-60 gaming and around 27 to 32 idle... I'm more concerned about the fact my chip is constantly boosting (on 1 or 2 cores) and showing 1.48v in Ryzen Master even though 8 of the cores are sleeping. I'm pretty sure I have something on here causing some kind of observer effect as my voltage actually drops when gaming or encoding. If I use the windows power saver plan thats the only time I see idle vcore drop to 0.7ish

That's perfectly normal and nothing to be worried about, the voltage changes dynamically and scales with load and frequency.
Low load + high frequency boost will result in high voltage to support the boost. High load with lower frequency will result in lower voltage to support a lower boost, power usage and temperature and keep it all within the FIT.

That's good to know, I've read about this observer effect and that it can be normal and nothing to worry about, but wasn't entirely sure with the idle voltage being so high and constant. Performance seems fine, temps seem fine so I'll leave it and not worry :)

Important thing to remember is that the idle window is very narrow with Ryzen, it will boost at the sight of any small load as it's quite sensitive, even system sensor polling with some apps. But it is perfectly fine and normal :)

You do know you can tweak the Windows Power profiles yes? A low 5% or even 1% low, results to the CPU snoring most of the time operating at minimum speed at 2.2Ghz 0.9v.

Yes of course, if you want you can drop it below the default 90% (about 3GHz @ 0.900v) although i'm not sure why you would need to really given the little load at whatever the voltage.
But my point was that "idle" is hard to actually achieve and it's default behaviour is fine and nothing to worry about.

When watching stream, or as typing here most cores are at 1866Mhz with couple at 2200Mhz at 0.9v. Only Core 5 goes down 0.2v and 1800mhz.
 
Cheers guys.

These temps don’t seem too bad. Some lower than the testing I’ve seen with the 37/3800x. Have any of the more recent bios updates helped things?
