My nVidia RTX 3080 ThermalRight Upgrade
Recently I traded my 2x Gigabyte RTX 3070 for a Aorus Masters RTX 3080 for a set of various reasons: For Ethereum crypto mining, a 3080 can achieve ~100MHps, which is very close to what 2x 3070 can do 1x 3080 definitely consumes less power than 2x 3070 If I play games or VR, only…

Ethereum(Crypto) Mining with Nvidia 3070(Ampere) on Ubuntu 20.04 with Renewable Energy
I’ve done Crypto mining before and since the price is now almost all time high I’ll do that again, but only with my solar energy. Mining with dirty coal power isn’t ethical any more as the climate change has accelerated in the past few years. To start ETH mining here are some prerequisites: Energy efficient…

Mining ZCash on Ubuntu Linux
I didn’t quite believe that mining crypto currencies is viable as an individual, until I saw the news that AMD graphics cards were sold out because they’re good at mining Ethereum. To be convinced I tried to order AMD RX 570 from some online vendors, and they all cancelled my orders and refunded me shortly.…

关闭 Dell XPS 15 9550 的独立显卡
最近我从 ebay 淘了个二手 Dell XPS 15 笔记本电脑, 2016年的而且配置很高, 但价格相当便宜. 既然好货不便宜, 这电脑是不是有问题? 是的, 卖家承认电脑的 nVidia 独立显卡有故障, 装好驱动程序之后 Windows 就会僵死, 但禁用了它之后一切正常, 当然就不要指望能玩什么像样的游戏了. 不过正好我也不打算在笔记本电脑上玩游戏的, 而且 Dell 对 Linux 的支持算是很好的, 于是我欣然买下. 电脑到手后我装了 Fedora 25, 一切顺利, 送走了 Windows 10. 顺便提及, Fedora 25 已经能检测到 XPS 15 BIOS 有更新可以安装了, 很赞. 启用 nVidia 驱动后果然死锁. 索性把 nVidia 关闭了吧, 还能延长电池的使用时间呢. 首先添加 bumblebee, 参考(在 Fedora 25…

擎天柱与大黄蜂
前些时, 我打算升级一下我的笔记本电脑, 作为给自己的生日礼物, 老婆很给力的批准了. 于是我稍做筛选, 购买了正在促销的 ASUS R501J, i7 处理器 + 15″ 1080P 的屏幕 + 16GB 内存, 我觉得够用了. 只是… 预装的是 Windows 8, 而且有 UEFI + SecureBoot. 微软希望依赖 SB 来阻止我卸载 Windows 安装 Linux, 但很显然他也不得不给自己留个后门, 我只需要照做就是了. 于是轻松关闭 UEFI + SB, 又看到了熟悉的 BIOS, 那安装 Fedora 20 吧. 好笑的是每一种企图剥夺用户自由的”科技”都会美其名曰为了保护用户不受”未授权”的软件的”侵害”, 哈哈哈. 安装 Fedora 20 在 R501J 上就像在茶餐厅点菜一样容易, 键盘上的功能键/屏幕/触板/无线网络/摄像头…都直接可用了, 不过意料之内的是独立显卡似乎被闲置一边了. 原来这就是传说中…
