Called my companies AMD tech group (servers) and had them take a look at it remotely. They have a very handy diagnostic suite that interrogates the hell out of the chip on the hardware level (tried to snag a copy and got my hand smacked (damn); two hours later and they said it was the TIM under the heat spreader. AMD flagged the chip's serial number and are going to RMA it back to the QC lab to figure out what happened and to see if more also got dodgy TIM (the 5800x and 5900s get soldered; not sure about the rest of the series) application in that batch; I doubt enough got messed up to warrant a recall.... at least I hope not. Due to the temperature spikes those cores are now damaged. So I returned it and got a store credit and a promise of a phone call when they get their next shipment. Statistically I was the one to get a dud chip; they randomly test chips after the head spreader is attached before they package them for QC. If they had to test everyone then they would never get them to market. When they test to bin them it is before they place the head spreader and test stability right on the core. They have a solid copper block cooler with a liquid metal pad thingy that they use to cool the core when binning them (have a picture somewhere I got from someone). I have my 3900x till then so I am not sitting with a pile of dismantled computer parts pining for a round of whatever game tickles my fancy at the time.

Sa speram ca e doar un batch cu ceva probleme, si nu ceva generalizat, altfel gasea si Monstru in review daca avea bube 5800x. Pe 5800x am pus ochii pentru un upgrade de la 3770k, in primavara cand se vor mai linisti lucrurile, nebunia cu scalperi, preturi nebunesti etc. Atunci va veni si Rocket lake, sa vedem ce poate.
Pacat ca nu sunt prea multe modele de placi de baza AM4 mItx, nu am nevoie de mai mult

Și eu am pus ochii pe 5800x sau 5700x pentru la anul când se vor așeza prețurile. Dar cum nu am mai avut chef să aștept până atunci am luat un 3800x să înlocuiesc vechiul 3770. Nici nu va mai trebui să caut alte componente, doar voi înlocui procesorul.

Am pus filmele aici cu default. Am diagnosticat si problema in cazul procesoarelor testate de el - folosea setari optimizate extrem pentru silent computing, ceea ce... pe Ryzen nu prea merge.

Am vandut 3800x si am trecut pe i9 10900 non k.Daca aveam b550 sau x570 stateam sa prind un 5800x la pret bun.Asa am prin la 1600ron 10900 non k,merge pe z490 la 4.6all core,suficient pentru mine.Cat plateam pe 5800x am luat i9 10900+z490.

Multumesc amd pentru competitie,scad preturile la intel.

1300-10700k sau 1600-10900 non k nu sunt preturi mici?

Tu compari prețul de magazin la lansare cu prețul de la sehaș, sau de la ce cade din Tir?

Compară ambele la prețuri de magazin.

AMD adaugă noi posibilități de undervolting cu PBO2 pentry Ryzen 5000, că tot se plângeau mulți că au temperaturi foarte mari: https://www.anandtech.com/show/16267...00-coming-soon

Aia de la intel ar trebui sa concedieze departamentul de marketing - asta am inteles eu din articolul ala

4 vs 8 core (4800u din ce se vede in grafice), buna comparatia asta, probabil cineva pe planeta asta va crede balariile astea, daca sunt repetate in continu.

E mult. La 3800X am avut cel mai mult 82 de grade cu în Prime95 cu Smallest FFT cu totul pe default. Overclockat cu bun simț, +500Mhz pe un CCX și +450 pe celălalt, 1.250V, am avut maxim 73 de grade în Prime95.

+400 Mhz pe fiecare CCX, 1.175V, am avut maxim 69 de grade în Prime95 Smallest FFT.

Aer, cooler de 130 de lei, carcasa închisă.

Cât ai la CPU Package Power în condițiile astea?

Ce înseamnă overclockat cu bun simt? Ce frecventa pe fiecare nucleu? E prime avx? Am avut atât 3700x cât și 3800x și nu am avut niciodată sub 75 de grade in prime avx. Și f important, ce frecvente ai in timpul testului

Cu bun simț - să nu îi dau voltaje prea mari. Prime Smallest FFT, adică AVX2, instrucțiuni care încap în cache-ul procesorului - teoretic aici se ating cele mai mari temperaturi posibile.

Am folosit o dată 4400Mhz CCX1, 4350Mhz CCX2, 1.250V - 73 de grade in Prime95 Smallest FFT.
Cu 4300Mhz pe ambele CCX și 1.175V am avut maxim 69 de grade în Prime95 Smallest FFT. După mine cam aici ar fi optimul.

Pune un printscreen. Dă-mi voie să mă îndoiesc de faptul că rula la 4300 all core in timpul prime avx smallest ffts cu la doar 69 grade, indiferent de voltaj. Poate sa fi prins un platinum platinum sample �� Și pune frecventa fixa fara pbo plus voltaj fix, altfel scade frecventa in avx, crede-mă.

Maxim ajunge pe la 71 dar se mărește viteza coolerelor și se stabilizează pe la 69.

Pune in screen și task manager-ul deschis unde se vad frecventele in timp real
