标题 [情报] GMP 建议不要用 Zen5

The GNU Multiple Precision Arithmetic Library建议不要用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."
烧坏的cpus

如果raptor lake是空烧烧坏的，Zen5看来是高强度数学运算会烧坏。
不是x3d才会，烧坏的两颗都是9950x。目前AMD是怪罪主机板商，跟当初Intel一样。
普通游戏玩家或ai使用者应该碰到机会不大。但网络已经够多人碰到烧坏的问题，而且不
是只有Asrock，所以应该是需要AMD出bios解决方案的时候了。
其实我一直认为5GHZ以上的频率都是神经病。我们应该往更多核与更大的内存频宽走。
目前看起来是关掉pbo会比较保险，如果能开eco mode更好。更强大的散热应该是帮助不
大。
