[情報] GMP 建議不要用 Zen5
https://gmplib.org/
The GNU Multiple Precision Arithmetic Library建議不要用Zen5
"Back in February of 2025, the main GMP testing computer, a Ryzen 9950X based
system, died. The CPU's pin side has a discoloured region of about 10 mm in
diameter. The CPU was replaced within the warranty period.
Unfortunately, now in late August, the replacement CPU died in the exact same
way as the old CPU. (The new CPU had a new motherboard and a new PSU for good
measure.)
Before this problem is fully understood, we must caution people against using
GMP heavily on any Zen 5 processor.
We suspect that GMP's extremely tight loops around MULX make the Zen 5 cores
use much more power than specified, making cooling solutions inadequate."
燒壞的cpus

如果raptor lake是空燒燒壞的，Zen5看來是高強度數學運算會燒壞。
不是x3d才會，燒壞的兩顆都是9950x。目前AMD是怪罪主機板商，跟當初Intel一樣。
普通遊戲玩家或ai使用者應該碰到機會不大。但網路已經夠多人碰到燒壞的問題，而且不是只有Asrock，所以應該是需要AMD出bios解決方案的時候了。
其實我一直認為5GHZ以上的頻率都是神經病。我們應該往更多核與更大的記憶體頻寬走。
目前看起來是關掉pbo會比較保險，如果能開eco mode更好。更強大的散熱應該是幫助不大。
