Why does AMD not show the maximum operating processor temp or default vcore?

For AMD Engineering -

Why does AMD not specify the maximum operating temperature and list the default vcore for their processors? The link below shows nothing in this regards. This information would help many AMD customers resolve operational issues with their AMD powered PCs.

This site should have the info :- http://cpu-world.com

Ryzen 5 5600x, B550 aorus pro ac, Hyper 212 black, 2 x 16gb F4-3200c16d kit, Aorus nvme gen4 1tb, Nitro+RX6900XT,

Unfortunately the linked site doesn't have the info. AMD certainly should have this info. on their site. You never know the accuracy of technical data on other sites.

Re: Why does AMD not show the maximum operating processor temp or default vcore?

Yes the linked site does have that info.You actually have to click on a specific processor:

FX 8350 for example:

Electrical / Thermal parameters
V core ? 0.9375V - 1.4125V
Maximum operating temperature ? 61°C
Thermal Design Power ? 125 Watt

Re: Why does AMD not show the maximum operating processor temp or default vcore?

The link you listed is for an old FX-8150 Bulldozer CPU not for the Vishera FX-8350 or later model CPUs. AMD has not supplied any FX CPU temps since the FX-8150 CPUs. That's a serious deficiency. In addition no vcore voltage is shown for the p zero state which is critical for full load operation. These technical specs are very basic CPU information that should be readily available to all consumers seeing as though AMD states their products are intended for enthusiasts especially with AMD promoting CPU overclocking. Even with a non-overclocked FX powered system these are vital specs required to determine if the CPU is overheating and if the mobo is supplying the correct CPU voltage as many do not.

So you have the info you were looking for ?.

But it should clearly be available on the AMD Spec. page?

(Intel don't give all either).

Re: Why does AMD not show the maximum operating processor temp or default vcore?

No unfortunately we do not have the information that AMD should be listing on their website under the CPU specifications. That is why I specifically addressed the original question to AMD Engineering. As previously noted AMD has not posted any FX CPU max operating temps since the FX-8150/Bulldozer models and there is no p zero state vcore voltage which is required to determine if the mobo is providing the proper voltage to the CPU under boot and full load conditions. The CPU temp and vcore are the first things you would normally check on a new PC build to insure reliable performance. These are critically important when running stability testing such as with Prime 95 or similar stress tests.
