Whats the maximum allowed Temperature of Ryzen 1800X CPU?
Max working temperature is 95°C
Thank you very much. I found out that my ryzen CPU trottels at 95,1°C
Is this a safe Temperature for 24/7 use?
I don't think so.It can lead to CPU degradation or overheating other system components.
Try to keep it below 90 C (80-85C would be nice)
UPDATE 3/3/2017: We have it on good word (not direct from AMD, but someone closely associated) that the core/die max temperature is 95°C
AMD Ryzen 7 1800X CPU Review - Overclockers
But why AMD isn't throttling at 80°C when 95°C shorten youre livetime for the CPU?
I think it is because 95C is safe temperature for short periods of use in such condition(short spikes)
If you will have constant temperature above 90 C it will be not good for your CPU. I am sure.
I have run the CPU now for 7-8 houres at 95 degree. Do I have to be worry about? Now I buy new cooler.
Several hours at such temperature will not kill your CPU, but you really need a much better cooling system. Probably liquid cooling.
Thank you for your answers. Now it's reported that 1800x have a temperature offset of 20°C. That means my processor runs at 75°C am I right?
Is 75 °C a good temperature to run 24/7?
I think it is quite safe temperature for this CPU.
Besides, current situation is that Ryzen CPU temperature may vary in wide range in depends of BIOS version.
AMD Ryzen 7 have a Temperature 20 Degree C Reporting Offset
Thank you for the answer. But I'm now totally confused. Here is said that my 1800x is running 20°C colder than showed in AMD Master Tool.
AMD Ryzen™ Community Update
So the Tjunction max is now at 75°C am i right?
But i thought running the CPU at Tjunction max with throttling is dangerous, also when it is at 75°C?
That means also 75°C is dangerous for 24/7 use?
1.Update BIOS to the latest version and contact motherboard manufacturer for the explanations. Some version of BIOS may set CPU voltage too high
2.95C or 75C - keeping your CPU at constant Tjunction max temperature can not be good.
3.Try to set CPU voltage manually to 1.2V-1.3V
I'm confused as well.
Does the AMD Ryzen Master software report the real temperature of the CPU or the temperature with the 20 degree offset?
I think for 1800X and 1700X it will show offset temperature (+20C from real CPU core temperature).
1700 (and below) has no offset temperature and all software will detect its real temperature.
i believe the maximum temperature allowed before burn is 120 c dide(before it melts(core centre process dide) and 210 c silicon relief beofore it spanes. (melts splits, separates, red up/black down (catches fire))
Upper safe zone is around 80c. It can go up to 85c under 100% load for something like rendering a video or some other heavy threaded task. You really don't want it going to 90c or above since that is too close to the tjmax value and will shorten the lifespan.
Having said all of that, there is 20c offset that applies when the cpu is underload. If you have the MSI X370 XPOWER motherboard the LED debug display will report the operating temperature of the cpu. How accurate this is I am not sure. I have compared temperatures between the motherboard LED and HWmonitor and have seen stuff like HWmonitor reporting 53c when the X370 motherboard's built-in LED displays 73c.
I am using a Noctua NH-D14 though so the cooling unit is robust enough to handle overclocking to 4.0ghz using auto voltage and load line calibration.
With 85°C safe zone you mean the actual temperature or 85°+20°C offset?
With ryzen CPU you can never reach more than 75°C+20°C offset. It's throttling at this point. Where can i contact amd directly about this question?
