New AMD Ryzen 7 2700X CPU running extremely hot

You can usually trust the bios readings. You can also open task manager (Alt+CTRL+DEL) and go to the performance tab and see if the CPU and ram are being used a lot. They should be on first startup, then calm down.

Installed a new AMD Ryzen 2700X CPU on my Win 10 Pro 64bit PC (v 1709 build 16299.371) and fans and pump went turbo. Used CPU-Z and it showed that the CPU multiplier was x42 which was making the CPU run at top speed and the temperature was 194.3F. Heard there was an issue with Windows and this CPU for this problem. Has anyone heard of it?

There is 10c temperature offset in Ryzen2 (was 20c in first series) confusing the heck out of users and some programs showing that much higher temps. As Ryzen Master doesn't recognize Ryzen2 practically only program accurate enough left is HW Info HWiNFO - Download
These are temperatures to watch for
Top one is without offset and bottom one is real core temp.

In these ones, CPU temp is so called "Package" temp measured at the back of processor.

Going to check one other thing. Prior to purchase, I checked the Gigabyte site for specs on the 2700X vs my mobo. That page specified that the mobo needed a BIOS update to F23d (from F2). That was done.

However, after this fiasco, I checked the page again and Gigabyte specified that the F22 BIOS should be used. That is now complete and I will try the re-install this afternoon.

Back with the results then.

Whichever BIOS, needs AGESA 1.0.0.2a code.
