Ryzen 7 3700X, 3800X/XT, Ryzen 9 3900X/XT a 3950X

[HEAD]

Ten kdo ma MSI b450 tomahawk, tak doporucuju v biosu zvolit pod PBO nakej advanced profil.Dost se snizi napeti ve win i ve hrach a ve hrach to bude porad boostovat na +- 4200mhz jako na default.

[simike]

tu teplotu na 3700x ani ja sam nechapem..nezdala sa mi so stock chladicom tak som kupil za 60 eur noctuu a stale je to skoro take iste ..ked neni nic zapnute tak to skace medzi 35 a 45 stupnov ked zapnem chrome 45-55 ..teplota sa doslova meni pohnutim mysi

[Mr_Trollfan]

taky doufam ze se vnitrne nehreje

Aj vykon mas nejaky nizky. V multithreade som s 1700X 4ghz len o 10% nizsie. Vlastne pozeram recky, ono to tak vychadza normalne, myslel som ze to bude vacsi upgrade.

Vydrzte na funkcne biosy, undervolt bude zaklad.

pro sledování teplot funguje korektně jen RyzenMaster a Hwifno, zbytek bych bral s rezervou.

Dalším důvodem vyšších teplot jsou bugy BIOSu, kdy je špatně nastavená voltáž na default (X570 to mají již pořešené) a také umístění CPU více na kraj IHS, pokud navíc je křivá styčná plocha IHS...

uz je to skoro na urovni intelu.Mozna vykon jeste zvedne budouci agesa

no nevim ja mam desku Gigabyte x570 Ultra.
kdyz jsem delal zatez procesoru v cpu-z tak hned po zapnuti naskoci teplota skoro o 20 stupnu nahoru.

a chudaci testeri. po prvnim zapnuti tam byl bios f2 a celej pocitat i bios byl tak hrozne pzasekanej a divnej ze stara 486ka byla delo.
Navic Bios zde neni zadna slava co se tyka rychlosti a prehlednosti. Na mem starem asusu z97 je bios nadherne sviznej a prehlednej pro duraz jeste jednou napisu sviznej

[simike]

je mozno ocakavat na B450 dosky este dasiu aktualizaciu po agese 1.0.0.3 AB ktora tie teploty zlepsi?

[mlrs]

tak minimalne do prichodu B550 klidne nejaka aktualizace prijit muze - asi zalezi na stesti/kusu desky (resp. danem vyrobci)

[Howkey]

Nekde jsem cetl ze by finalni verze agesy mela byt 1.0.0.7.

[havli]

Co se tyce teplot, tak ja mam na 3700X pri delsi AVX2 zatezi cca 80°C. CPU je na default nastaveni a chladic Ninja 4.

[AllowedCry]

Jaký je boost v AVX?

[havli]

Jadra se pohybuji mezi 3,85 az 4 GHz.

Dokud nezlepší přístup do RAM, budou furt vzadu. To je momentální problém Ryzenů.

Dalsi update z redditu
https://www.reddit.com/r/Amd/comments/cbls9g/the_final_word_on_idle_voltages_for_3rd_gen_ryzen/

EDIT 7/13/19 @ 18:28 UTC If your BIOS has the option to set CPU voltage to AUTO or NORMAL, please try setting it to normal. Please also make sure you've installed chipset driver 1.07.07 from amd.com. I have received reports from several people that this resolved their issue. We continue to diagnose the reports, though, and appreciate the data coming in from the community!
EDIT 7/18/19 As a temporary workaround, you can use the standard Windows Balanced plan. Edit this plan to use 85% minimum processor state, 100% maximum processor state. (Example). This will chill things out as we continue to work this issue. Your 1T and nT scores shouldn't change at all (+/- the usual run-to-run variance). This will preserve boost, retain cc6 core sleeping, preserve idle downclocking/downvolting, but make the CPU more relaxed about boosting under light loads.
Please note that it is totally normal for your Ryzen to use voltages in a range of 0.200V - 1.500V -- this is the factory operating range of the CPU. It is also totally normal for the temperature to cycle through 10°C swings as boost comes on and off. You will always see these characteristics, as they're intended, so do not be surprised to see such values.
Please do not undervolt the chip or set a maximum processor state of 99%. These are ineffective and/or detrimental changes.
We appreciate the reports everyone has provided, and they are helpful. I will make an all-new post when I have a more comprehensive update to share. Thanks for your patience. ♥

Undervolting AMD Ryzen 9 3900X
https://www.legitreviews.com/amd-ryzen- ... 00v_213060
Výkon klesol dosť výrazne, ale spotreba sa znížila o 77W.

https://www.overclock.net/forum/28044514-post7.html

Its not wise to undervolt Matisse, unless you enable the OC-Mode (fixed frequency).

That's because the CPU is constantly monitoring its supply voltage.
When it sees the supply voltage below the desired level, it starts increasing the VID request from the VRM controller.
When the VID request increases above the maximum voltage allowed by FIT, the clock stretchers will kick in. Your performance will decrease, despite the change is not visible
in the frequencies diplayed by the usual monitoring software.

For example on the 3900X sample I have, the default VID request during CB20 NT is 1.3125V.
With the offset set to -25mV the VID request raises to 1.33125V or so. At -75mV the VID request is already 1.36875V and increasing the negative offset any further will trip the stretchers.

There is an undervolting margin available, but it is tiny.
The exact behavior will depend on the silicon specimen and the workload.

Its also the very reason why this guy thinks he is running at > 4.2GHz with just 1.00V...

Mohl se se autor pochlubit i teplotou při 1V v-core.

já osobně si počkám na EUV verzi Ryzenu a až bude odladěná platforma ( RAMKY + nové čiplet zapojení ) Není vůbec kam spěchat.
