这个project从“13.82.98.119”，“fah3.eastus.cloudapp.azure.com” 过来的，微软云就是给力。下载上传比 ...

40.114.52.201，13.90.152.57，13.82.98.119都是，下载上传很给力

所以我的2060 PPD不算高的原因可能跟CPU差有关？i3 4130拖了后腿

理论上如此。

我在32线程的机器上开算13873时，在启动计算初期CPU吃满32线程，几乎瞬间开始GPU的计算，

而在8线程双卡机器上启动计算需要过好几分钟后GPU才开始计算

看了一下log，正常TPF大约是2分6秒，从第一个百分点开始，每5个出现一次TPF增加18秒左右，没有出现几分钟的差距，感觉还好

那看来这个beta包在计算到某个环节上消耗不少CPU的资源，带4卡的话看来要把这个X79的U升级到2697 V2才行了。现在这个3930K捉襟见肘。
而且并非是4卡5线程就够，我看到有时候光单个FahCore_22.exe在高峰的时候要用掉我现在6核12线程CPU大概75%的资源，后面会降到37%左右。

看来以后单U平台要上X99来搭配16核的服务器U才行了。

或者dual cpu C602配4卡。

Keyco

还发现这个beta包还很吃内存，8G内存用掉100%。。。
看来以后标配是要16核CPU外加16G内存才能带动4卡跑beta了。

用了1分钟，还好，后续每5%一次CPU矫正计算也是吃满所有线程

兄弟的3930K基本上可以带4张2080TI跑13873包，每5%矫正一次，会拖一些PPD后退。
但是内存貌似每个内核1.5G上下，你四张卡加系统占用，最好12+G内存

意思是CPU的话，不管多少核，都会吃满对么？
区别就在于吃满的情况下，越是核多，越快的完成矫正，PPD越不会被拖累。是这个路数么？

那么CPU的话，建议是高频还是多核呢？还是频率*核数要尽可能堆高？

1660Ti+8700，开头CPU需要满载30秒，每5%的时候满载大约12秒（同时挂着三个线程ARP），TPF2min45s

是的！
在我的双路E5-2687W上，一个core22内核吃满32线程，二个内核也是吃满32线程，单个时基本上顺开GPU计算


PS：感觉是多核作用更大

不行只能整个平台换成X99的了。

前面把8G的闲置内存加上去了。确实，fahcore22在内存足够的情况下，从占用了1.3G开始慢慢变成了1.66G，加上teamviewer，msi afterbuner 以及 elsa  system graph，这些已经达到了8G+。看来是要准备至少10G以上才够，所以一步到位16G。
