So I’m fairly sure I have a bad CPU, but here’s story.
I was upgrading to a Ryzen 5 3600x from my 1600x and to a new motherboard, Asus x570-P.
They both arrive and I got them set up. First thing I notice is that my CPU temps idle high (around 40C to 50C), I thought ok, maybe it’s an offset thing or something, so I get the latest chipset drivers, update windows, update to the latest HW monitor and GPU monitor (has a CPU temp measurement) and I get Ryzen Master just to be sure. They all report the same temps and idles. (Of course I ran everything one at a time). Then I thought could be the cooler. So I tried the stock cooler, a Noctua NH-U12S, and a Deep Cool Captain EX white, there was NO CHANGE to the temps, they were all the same at idle and load.
Then I thought, maybe it’s the motherboard, so I went back to my old motherboard (MSi B350 Tomahawk Arctic) I flashed the BIOS, and installed the 3600x…SAME DAMN TEMPS!!!
Is it just me, or do I have a bad sensor on the CPU? Or a bad CPU in general?
Full disclosure, since the temps seem so high, it does seem to thermal throttle and all core clocks seem to settle on 4.1GHz. Whenever I run cinebench R15 I get between 1595pts up to 1605. I know the 3600x can do a bit better than that consistently. When running the benchmark temps go as high as 76C (and that’s on the Deep Cool water cooler on stock clocks!)
I also tried lowering the voltages to 1.3 - 1.35, all it does is lower its performance.
I REALLY wanted to do a all core overclock to 4.3GHz, but at this rate, it doesn’t seem like I’ll be able to.
I don’t think so. It seems like voltage control in the BIOS has issues in general on X570 at the moment.
If you are on windows you can try that Ryzen master software thingy, that seems to be working better for now.
Or just wait a bit. Things will even out over time.
@noenken, that’s just the thing, the same thing is happening on 2 different motherboards with very different chipsets. MSi B350 Tomahawk Arctic and the Asus X570-P. Both updated to the latest BIOS. Also both have been updated to the latest chipset drivers.
I also did try Ryzen master, as I’ve mentioned in my original post. It reports the same temps as any other monitoring software.
But yeah, maybe things may iron out over time…I REALLY hope.
Hi there @nerodante87 . I built a Ryzen 3600X system today on an MSI B450M Mortar motherboard. Using the stock new Wraith Spire cooler, I too get around 40-50 degrees at idle according to the Ryzen Master program.
Don’t think we’ve got bad CPUs although I’m not certain yet about what is causing the high temperature readings.
So from all the reviews and tests i’ve read/watched to date, your results fall in line with almost everyone else.
Ryzen 3xxx in general doesn’t seem to overclock at all and most people have Problems reaching the rated all-core boost at all. Wendel said some things about that in his 3700X review (i think).
Also, Voltages being high in idle states seems to be normal as well.
Not sure on those temps, but 60C is well within spec. It might just be the case, that they are designed to not go lower (and most reviewers report similar temps).
Overall, i think, it’s just a case of Zen2 being a completely different thing than Zen or even Intel. Measuring those chips and expecting similar results seems not to work.
Also, keep in mind, that the rated max-boost clock is for single core only afaik. And it gets lower the more Threads you are using. So 4.0 could be pretty normal…
You have that ryzen driver and does it actually downclock?
You can play a bit with the power setting, minimum processor state, mine defaults 90% and back with shittier taichi bios I had to keep it like 0% as either voltage or hertz just didnt play along at all and maybe it went halfway down with either one
So from what I described on my original post. The readings were taken from two different chipsets/motherboards, X570 and B350, with their respective latest drivers, and three different monitoring softwares, GPUz, Ryzen Master, and Hardware Monitor. All three monitoring tools were run one at a time so no other monitoring software interferes.
I used to think that the sensors were in the motherboard, but since I’m getting the same temps on both, I’m guessing it to be either on the CPU itself or it’s a software issue.
LOL lowers performance at same clocks? Thats not exactly possible man. Look ill be frank… keep it under 1.35 and your good. You want to do 4.3 GHz on a newly adopted platform? This doesnt seem realistic. Just wait for the EFI to mature a bit its not the CPU but the mobo manufacturers…just chill and wait 4-6 months for things to even out before pushing your overclock
Lots of EFI tweaks can prevent the OS from controlling the clocks as much
We are talking about how undervolting has little significant impact if done correctly. That being said the reason you dont want to push voltages past 1.35 V on ryzen is for electro-migration reasons amongst other things
Again, I don’t think you understand what is beeing said.
OP tried increasing clocks
and got “thermaly limited” so he tried to decrease voltage
wich resulted in lower performance at the same clocks.
I get what you are saying about overvolting and what effects it has. Wich is nice to know, but not helping when the question is what lower voltages do to performance while clocks appear to stay the same.
