使用「电子垃圾」级的电脑还能用得舒服是一种怎样的体验? 第1页

我最喜欢电子辣鸡,最喜欢50一块的主板,还喜欢老板嫌麻烦都懒得从主板上拆下来的处理器,20的内存 20的硬盘 30的电源然后把他们装一起,然后来一局英雄联盟,骄傲的看着打团也不算太低的帧率

舒服不是说这种电脑体验有多好,更多的是体验那种把辣鸡装在一起还能用的感觉

如何评价使用“电子垃圾”级的电脑还能用的舒服的人?

当然俺是其中一位, 家境贫寒苦中作乐可以一言以蔽之。

评语您没看到吗?

自评:“家境贫寒苦中作乐”。




800 刀买了电子垃圾。

内存配置低,还没到一个 TB;

性价比也有点低, 基本上没有3D加速;

价钱还不到三倍的运费,完全符合“韭菜机”。



详情第一部分写了篇散文:

第一次用 256GB 内存的电脑 -- 麦文学看图说话系列


话说 1996 年的时候, 俺就用过内存 256MB 以上的电脑, 从那时起就对内存有了一种畸恋 (Fetishism).



最近报完税了,兜里还剩点零花钱,思量着买个电脑来玩玩。最后看上了带 256GB 内存 (32x8GB)+ 24核CPU (4X6c) 的Dell PowerEdge R900 .

经过漫长的等待, 冰天雪地的早上, 终于到货了。 快递公司的司机问, 这纸盒里面啥玩意那么重, 差不多 100 磅了, 不会是尸体吧?俺说是俺的二手电脑。运费 300 多刀。

俺手无缚鸡之力, 一个人根本抬不起来。 用滚的办法, 一路将箱子滚到了地下室, 再用滚动的办法把开了箱的电脑滚上了架子。

上个玩家在里面装了个 Windows 2012 Server 评估版, 俺觉得碍眼就用 Fedora 把它替代了。

如图:


分享一点经验:


  1. 风扇声音确实有点大,如果只插上一个电源 开机后的几十秒,和半匹~一匹马力的吸尘器差不多。(机器认为是故障,所以风扇不降速)

2. 如果插上两个电源, 正常运行的时候, 风扇声音会下降很多很多。 如图:


3. 32 条 8GB 内存, 在运输过程中可能会松脱, 松脱的话黄灯会亮。

4. 软起动, 例如 reboot , 不会再发出喷气机般的巨响。

5. 耗电量明天再测。



电脑和耳机有啥关系呢?

俺打算用这个电脑来仿真电路, 而且这个电脑还不够一个 Sennheiser HD800 贵。

您信吗? 俺信了, 而且买回家了。

256GB 内存 (32x8GB)+ 24核CPU (4X6c) 的Dell PowerEdge R900


当然, 这是俺 DIY 家庭微型集群的第一步, 敬请大家指点:



贝奥武夫机群(Beowulf cluster),又称贝奥伍尔夫集群,是一种高性能的并行计算机集群结构,特点是使用廉价的个人电脑硬件组装以达到最优的性能/价格比。得名于古英语著名史诗《贝奥武夫》。于1994年最早在NASA为Donald Becker等人开发,是目前科学计算中流行的一类并行计算机。最常见的方式是把相同个人电脑作为组装单元,运行Linux或BSD系统。各个单元之间通过小型TCP/IP局域网和有关的程序库来分配计算任务和通信。常用的并行程序库包括MPI和PVM。


【更新】

运行了一夜,没有什么问题出现。每一条ECC内存似乎都是好的:
