嗯 老外有个介绍说:
“
VCC/VCCIO/CPUIO: Vcc is the voltage at the IO (Input/Output) terminals to the CPU. Generally at 4GHz or under this doesn't need to be adjusted, but at 4.5GHz it can require a small bump to between 1.15V and 1.2V, depending on the quality of your CPU. Using over 1.2V should only be necessary if you're pushing the CPU toward 5GHz or more. Equally, if you're using the maximum memory multiplier, you will likely require about 1.25V here. Using over 1.4V is not recommended at all - you have been warned!

他只提到在超频时可视u的体质 适当调整VCC
4.5G可提到1.15V~1.2V
没有直接说这个东西跟内存相关
===========
哦 还说到内存极限的时候 这个也需要1.25v
不过也许有点夸张 |
