Oct 23, 2019 · High temps are actually more common with the single chiplet variants of Ryzen 3000 than the 3900X. In the 3900X the total package power of 144W is split between two chiplets, for 148mm^2 of surface area contacting the IHS. Heat density is 0.97W/mm^2 there, vs 1.19W/mm^2 for the 3600/3700 and 1.96W/mm^2 for the 3800X.

Feb 21, 2020 · Thank you, black_zion. I had hoped for at least one direct answer to my simple question relating specifically to the 3900X at idle, and you did a great job in providing it. I understand now that the un-core is probably responsible. Though it still would be interesting to have a 3900X owner say what they see for this value in HWInfo.

Aug 4, 2019 · This 3900x I have has been very good, but I live in a hot country so temps are always a little bit higher. Undervolting drops overall performance by ~23% in Cinebench R20, but very significantly reduces temperatures. I underclock the CPU to 3GHz all core, and use 1.0125 vcore (actual 1.016v).

Aug 20, 2020 · 84*C is perfectly fine, and to be expected, on the 3900X with the stock HSF. The thermal maximum is 95*C, so well within the safety limits.

May 16, 2023 · Hello! I have a 3900x and i get 60-75ish degrees C when gaming. Is this type of temperature normal? I have a Arctic Liquid freeze 2 360mm and it also jumps to 50ish C when clicking on a youtube video, is this normal???

Nov 21, 2020 · Currently looking to overclock my 3900x, I've been enjoying it since July. I'm currently making my first attempt at overclocking with this chip since I have the time and would like to know what is a good starting place. RN I just have PBO on with a -.1 voltage offset, using Dark Rock Pro 4 as my c...

With a 3900X or a 3950X running the CPU with SMT off for gaming (I run my 3950X with SMT Off most of the time) is worth it to me for the extra 100 MHz per core I can apply. Another bonus of course is that even with the extra 100 MHz the temps are still lower than running the CPU with SMT On and playing games which cannot make use 32 Threads or ...

Jul 26, 2019 · To AMD why your new processors never hit advertised boost speeds in single or multi core performance. I have Ryzen 3900x with Asus X570 Prime Pro board running latest bios and AMD chipset drivers. My single core boost is maxed at 4.2Ghz and multi core at 4Ghz. Doesn't matter if PBO enabled or not. T...

Feb 9, 2020 · Hi all, I am seeing an issue wherein my AMD's 3900x core 0, 1, and 2 are stuck at around 500 Mhz clock speed. All the other cores are running as expected, except for the first three. This issue is intermittent. I have attached screenshot from CPUID HWMonitor: I let my system run for about an ho...
