Ryzen Master Curve Optimizer doesnt work properly

[akszon]

Hello,

i have a new pc and from last 2 weeks i try to configure it with UV for gpu, cpu, setting fans etc., I haven't had a pc for almost 8 years, so everything is new to me and I have to learn everything from scratch.

I read a lot about undervolting with ryzen master and Curve Optimizer, but it seems its completely not working on my system, to put it simply, it sets the values that I set as maximum, if I set the maximum offset to 30 it gives -30 to all cores, if I set it to 33 it gives -33, and interestingly it sets the first core either to -50 or -255.
During tests in cinebench, 3dmark, mem64, my system reset at random times, I thought it was the memory's fault, I tested them using mem64 on various settings, but there was always a reset at some point.
I finally figured out that it might be a cpu issue, and in fact, after turning off the UV, the resets stopped.

Has anyone had a similar experience? maybe some hint as to why cu doesn't work at all for me?

I have all the default settings in Ryzen Master, when it starts I go to basic mode, run Curve Optimizer, and then in advanced mode I check what values it has set.

After reading your specs I suspect that your CPU has already been refined by AMD to run more efficiently than other chips. It has a 65 Watt TDP That as far as I know is the first AM5 chip to have that low a TDP. The 7600X has the same cores but a 105 Watt TDP. Simple answer, you may be trying to achieve what you already have by deciding on the chip you purchased. Just out of the love for tech. Where did you get a 7500F and does that mean it has no IGPU?

Any non-X Ryzen 7000 has a 65W TFP, I just don't know if they (7600, 7700 and 7900) came earlier than the 7500F. I think yes.
About Ryzen Master, I never got it tuning the Curve Optimizer for my 5600X reliably, so I did it by hand on my motherboard BIOS settings. Trial and error, and whenever you think it's stable, relax it a bit more.

It has no iGPU, i bought it here:

https://www.x-kom.pl/p/1175398-procesor-amd-ryzen-5-amd-ryzen-5-7500f-oem.html

now its 100PLN cheaper than when I bought it (i paid about 210$), now its for about 190$.

As for the power consumption, this value from AMD 65W is not true, for me this processor consumes about 100W under stress. After UV 80-90W (ofc in 100% usage).

And undervolting gives a lot for this cpu:

before UV:
cinebench r23, ~74C ( fan set to 800 rpm), score ~14400, CPU kept a ~5000 MHz, voltage: ~ 1.1V, power consumption ~100W

after UV:
cinebench r23, ~63C ( fan set to 800 rpm and with fans ~1100 it was 58-59C), and score ~14100, CPU kept a ~5055 MHz, voltage: ~ 0.9V (i guess its too low XD), power consumption ~80-90W

If you're using PBO the power consumption goes up, this is normal. Try a setting of -15 all core and test for stability, -30 allcore is fine for some cpu's but it can freeze the system when it's idle.

Any more than -15 on your preferred cores will cut performance (check Ryzen Master for the star ie preferred cores), they need 0 or -5 offset for best boosting performance. Your non preferred cores should be able to go anywhere from -10 to -30 without issues.

It's not that it doesn't work, it's that it isn't simply a set and forget value and you're facing consequences of that. You have to test the stability properly.

so far i used Curve Optimizer in per core mode, today i tried all cores mode and results were even worse, -45 offset on all cores. To as adviced by wNotyarD, ive manualy set -23 on all cores except for the two best ones, and after few hours of aida64 system seems stable ;}.
