AMD Ryzen "ZEN" (1000 CPU / 2000G APU series) Info thread

ryzen prve generacije na 4.5ghz, nice samo pazi na napon, za daljnju upotrebu osobno ne bih isao preko 1.45v, i to je puno, 1.4v max i iz toga izvuci sto mozes

[Brko]

Krivo govoriš nije to lntel da se treba bojati magične granice 1.4V. Ryzen ide onoliko koliko se može hladiti. Ako mu sa tih 1.45V temperatura ne prelazi 90°C, nema greške.

To sa naponima su dugogodišnji strahovi od korištenja lntelove tehnologije, veze s vezom nema sa ovom arhitekturom

ha dobro onda, nek ga przi, ali mislim ono 1.57v mu je screenshot. no treba gledati i siru sliku, sto je sa plocom, stres po VRMovima...

[Brko]

To je drugo VRMovi, ploča može li podnijeti i to. Što se samog proca tiče, napon ga ne boli, samo temperatura.
1.57V ako mu radi stabilno, može skenjat ploču .

Ček, sam malo, jel to Ryzen 1. gen na 4.5 ?

Jel to stabilno, provrtili se neki testovi ili je samo kliknuto 4.5 u Ryzen Masteru i to je to?

[extacod]

samo kliknuto, na onoj slici di je 4.3GHz tu je stabilan i tu se daju vrtit testovi

[nub]

4.3hgz na 1.5v huh

Kolke su temperature, s čim to hladiš?

[Max_Damage]

Imam problem (mislim) s mojim 1600. Imam u pozadini hwinfo upaljen i kada recimo surfam, temp mi naglo skače, sa idle koji je na otprilike 42C mi zna skočiti na 53C i onda se nakon par sekundi smanji. Naravno, tad i kuler počinje spajkat, sa idle 900rpm skoči na 1300rpm. Očito nekaj sa auto postavkama ne štima.. Da li bi OC riješio problem da malo smirim voltažu? Thnx svima na odg, njub sam kaj se tiče toga (OC)

[Overclock_freak]

i gdje je tu problem ?

[Manuel Calavera]

Mislim da je to normalno ponašanje.


Bitno ti je koliko je u loadu...ljudi se iz nekog razloga previše opterećuju sa idle temperaturama

[Max_Damage]

Ma nije toliko radi idle temp nego kaj mi za svako spajkanje naglo diže rpm na ventu pa se čuje. Živcira, pogotovo navečer kad je tišina. Igrao se sa krivuljom u biosu ali očito neuspješno....

Znači, ovo dizanje temp je normalno, samo trebam riješiti problem sa ventom. Danas idem po freezer 33 pa ću vidjeti kak će se ponašati.

Hvala svima!

[Manuel Calavera]

Ako googlaš ryzen idle temp spikes vidjet ćeš da to imaju svi (oni jumpovi na sekundu). Iako kad sam ja jučer gledao nakon tvog posta nije bilo te se vrtio stalno na 33C, no znam da je i meni bilo tako. Iskreno nekoć sam mislim i znao zašto je to, ali sam zaboravio

EDIT

Ovaj prvi quote je vjerojatno obješnjenje (toms hardware pod "solved" post)

OK...I tried some of the different power plans and found the Low Power plan does what I want... sort of.

I suspect the reason it's popping up in temp is because of background tasks that are (almost) always rummaging around in a Win10 system and the aggressive nature of Ryzen Balanced lets the processor 'boost' speed quickly for them with the accompanying temp spike to rev up cooling in case the load is sustained. Even default Balanced plan lets it boost 4 cores and that's enough to spike temps (the other 4 remain parked). But Low power plan doesn't boost so aggressively and therefore it's not spiking temps until a truely demanding task comes along.

All the Ryzen Balanced plan seems to do is let all cores (8 in my case) boost with every little background task that comes along but no more agressively than default Balanced. I think this is good for benchmarks, especially in games, as that's why it was created.

In everyday useage (OS navigating, browsing, document editing) it seems to be just as responsive but I'll see how it reacts as I play some games next. I'm sure a sustained heavy load such as a video encoding will result in all cores boosting to full speed. Any delay imposed by the low-power plan will be unnoticeable except in a benchmark.

Windows has a lot of maintenance services running in the background while "idle". It never really is idle, unless you turn the computer off.
If monitoring is supported already, do some tests from under a live linux distro. They have a lot less going on in the background.

Usage seems to spike in correlation with the temperature spike, so clearly there's some background process that keeps kicking in.

1600 here. Same thing. Went away after i stopped using ryzen master . still spikes a wee bit but Thats because of background processes. Biostar gtn here

I see similar spikes, but they correspond with usage. At (mostly) idle it appears flat. I've got Steam, Battle.net, Vivaldi, and a few other programs running in the background.

I had the same thing but then disabled core performance boost and now things are ok.

Vent:

Use a fan control app or see if you can set a fan curve in the BIOS. Change the temp at which the fans speed up to be above the temp spikes. This solved the issue for me, will only start to rev up above 40-45C

If you are having issues with FAN spinning up every X seconds... Change your FAN profile etc to CUSTOM in the BIOS and raise the temp limit... This will fix the issue while NOT damage your cpu or anything else related to this..
This is due to ryzen have the small spikes and then the computer thinks it has to kick in with the fans due to a long "load".. but since the spike is only there for ˝ a second... it does not negatively impact the tempature... but it does negativly impact the CPU spinning up due to the "fake" load...

Mine as well; I get a spike of +10c every 15 seconds or so at idle.
I had to smooth out my fan change interval to 1s from 0.1s in bios or this spike made my fans constantly ramp up/down.

Ma normalno je da malo skače kad surfa. Bolji cooler će moći držat temperature na svim razinama niže i dat će se postavit bolja krivulja, tj. da ne ulazi u helikopter mode pri nekim manjim opterećenjima.

[Manuel Calavera]

Osim custom krivulje iznad tih spike temperatura zanimljivo je i ovo rješenje "fan change interval to 1s from 0.1s" (tip sa b350 tomahawkicom). Dok neki tvrdi da je to rješio sa gašenjem core performance boost, drugi promjenom power plana (da nema tako responzivne micro boostove). Uglavnom nije problem nego je tako zamišljeno...

[Max_Damage]

Manuel, respect!

[BladeRy]

Imao to sranje da je svako malo temp skakao za 10c, a i voltazu je dizao na 1.5v. Na kraju otkrio da je krivac performance boost od ploce. Nije mi se dalo flashat bios, samo sam izgasio taj boost. Prestali cpu temp i volt spikeovi.
Nije bilo bitno jel load il idle, jel na cistom desktopu il sta, dok nisam izgasio boost to smece nije prestajalo.

[thunder11]

Mislite na ovo ?


Jer mi je to vec tako barem nekoliko mjeseci i nikad nisam razumio zašto...ide temp gore-dole bez prestanka..
