AMD Ryzen 9 3900X 12-core, 24-thread unlocked desktop processor with Wraith Prism LED Cooler

Works as advertised.

It worked fine at first, but after a few months it started freezing and displaying a matrix of green squares. A reboot got it back working. Montoring the CPU and sytem tempuratures gave a stong indication that it probably was not overheating. The fault was not with the graphics card (that worked fine on another motheboard). The engineer at my local PC mender said that he has, in the past had to send back a Ryzen CPU - he adds that AMD gave no problems and the replacement worked fine.

love it!!!! great performance.

Switched from intel to AMD and i think its a wise choice for me as my budget is tight.

Died after 6 hours of use. Bought a second chip (from a different retailer) that died after a few days of use. Back to using my 2700x after $1200 in silicon failed. Ive been an AMD fan for a long time and even stuck with them through their rough bulldozer days. But this rate of failure has shook my confidence in their product.

AMD is finally coming around and becoming the king once again. I have been building custom PCs for fun for hte past 20 years. Builds hundreds of machines and could not be happier to support this company once again. I dont need to say much as most reviews have already addressed how good this CPU is. Now is the time to break away from Intel and support a company that gives us better than 10% improvements between generations..

AMD clappin’ cheeks with this one.

Payed 499.00. Runing on Asrock 450m.. custom water loop. The thing screams in games and rendering. Even put it for fun in Asrok killer x370... ran every bit as good after bios update as my B450m.. originally about it for a gig x470 gaming 7, but built a micro on the AsrockB450m... That is its new home with 32 gig 3200 gskill, pci-e NvMe

The Tctl temperature that motherboards use as a proxy for CPU temperature on this chip is a raw value with no moving average applied. So at idle at least every 10 seconds it will jump 10 to 15 degrees C (18-27 F) for a split second before dropping back down to the CCD 1 & 2 die temperatures. That sets the included Wraith Prism off toward full RPM with a loud roar. Of course, before the CPU fan even has a chance to significantly increase speed the temperature has dropped back down. But the fan wont know that until the next temperature reading so the fan continues loudly toward full max RPM. A few seconds later the fan drops its speed back down, only to have the cycle repeated about 10 seconds later. Really ANNOYING.
