New AMD build updates bring some changes to BIOS tweaks and potential overlooked details.
New AMD build updates bring some changes to BIOS tweaks and potential overlooked details.
I'm wondering if these temperatures fall within a reasonable range for the 7800x3d with an air cooler. The room temperature is around 70°C, CPU idle was between 37-40°C, but during gaming (playing Darktide) the CPU stayed at 83-85°C for about half an hour. I haven't assembled an AMD system recently and haven't used an MSI motherboard much. This build was for a friend, so I wasn't convinced to choose an AIO. Maybe I need to tweak the fan curves in BIOS or this chip is overheating. I'm still learning about BIOS settings, comparing MSI and Gigabyte, and the fan curves are currently set to default with the resizing option enabled, DDR5 at 6000MHz stable (without AMD expo).
I haven't turned off the integrated graphics yet—would that help?
Does AMD offer something similar to Intel's Insta 6GHz? I think it might be PBO, and if so, can I turn it on without raising temperatures too much?
Are there any other BIOS adjustments I should make besides what I have now? If possible, could I lower the CPU temperature to around 75°C?
First Timespy benchmark: 24,985 CPU @ 81°C, 12,325 CPU score (low), GPU @ 61°C, GPU score 30,355 (average).

Thanks for the advice!
The only solution to reach 7800x3d at 75c is using an AIO 360mm +. My 7800x3d performs well between 80-83 with the Noctua NH U12a and 83-85 with the deep cool Ak500 digital, around the 80s using the NZXT x63 280mm aio in R23 allcore! I’m not sure if PBO tuning the X3D CPU helps lower temperatures, but I’ve noticed it can make a difference. When I used the 7600x with an Arctic Freezer II 420mm aio, it never exceeded 75c in R23 allcore. Overall, I believe like most Zen4 CPUs they don’t really throttle until they hit the 95°C mark, so 85°C is fine!
The method for running Ryzen coolers involves curve optimization, which is essentially undervolting. As the CPU speed increases, the voltage should also rise, though not as much as the default setting. By adjusting this, you can lower power consumption and reduce heat generation. There are videos available that show this process, or you might want to explore "Ryzen master"—I achieved solid results by lowering my 7600x from 120w and 90c to 70w and 70c without affecting performance.
