Tony哥的矿渣日记
昨天晒了一下帮邻居淘的蓝宝石RX470D 8GB显卡，今天得空把这块179入手的蓝宝石老矿渣RX470 4GB单HDMI版上机测试一下。由于打算用它和上个月淘的鑫谷老矿电源一起攒个3乃机玩，所以装机前稍微拆解整备了一下，闲话少说，老规矩看图说话：
外观目测7~8成新的样子，比车队群绝大多数车友们收到的卡成色都要差内心不平衡+10086
背面PCB标注了1736，也就是2017年第36周生产的（PCB板），实际售出的时间应该在2017年40周~44周左右，到现在也5年多了，可谓多朝元老。
散热片上参差不齐的变形意味着这货起码经历过一次以上的拆解，正常使用或者物流状态下是不会损坏到这些位置的。
2018~2019年很多这类单个HDMI或者DVI接口的挖矿专用卡，后期Nvidia也有干脆无视频输出的纯算力卡，对于零售用户而言，不能多屏输出也是个功能损失。
由于我收到显卡比较晚，之前看群里车友们表示显卡烤机和游戏温度都在75C以上，按说这种没有刷RX580高功率BIOS的显卡不该这么热，所以干脆在上机之前彻底清理维护一下，以免日后麻烦。
拆掉背板所有螺丝，取下散热风扇，散热片上的物理损伤更多，核心处鳍片的物理变形稍后要处理好才行，不然多多少少会影响散热和噪音表现。
镀镍铝片的物理形变很容易解决，一字螺丝扳手或者尖嘴钳就可以搞定。
风扇部分显然也是被处理过的，封口贴纸没有拆换过的痕迹，估计多少得上点油了（稍后处理）。
拆下散热片，GPU处的硅脂显然更换过，从粘稠度方面来看其实还可以，至少应该有硅油版7783或者道康宁10元一管的水准。
显存散热垫依然是原厂自带的，虽然脏不拉几，但不影响使用，可以不去管。
尴尬的来了：显卡供电模块散热垫缺失()
问题来了：供电模块上的导热硅胶垫没了，对于一块额定TGP约122W的显卡来说，长期没散热肯定会有影响，尤其是过段时间入夏之后，这个稍后需要处理。
尔必达的显存，目测也就1750MHz的样子，我也懒得给他刷BIOS，性能提升忽略不计，温度和发热以及稳定性肯定受影响。
显示输出部分，只留了一个HDMI接口，配合显示器以及HDMI线缆支持到位的情况下，也可以输出2560x1440/144Hz的屏幕，不过在我LG 27GL850的显示器上只能输出1920x1080/120Hz以及2560x1440/100Hz，只要不是60Hz就好，起码够用了。
其中一个散热风扇噪音有点大，拆下来做一下维护，顺便看到出厂日期为2017年5月19日，这个风扇质量还可以，且由于出货量太大，市面上替换的全新备件也很多，十来块一个甚至能买到带灯版的。
封口贴纸已经完全老化撕不成整个的，喷了些除胶喷雾（车站6块9到手常见的那种）
这里就是轴承底部，噪音基本来自于此。
用牙签或者小刀把上图这个带有缺口的白色小圆垫片取开（千万别丢！丢了风扇就没用了），即可抽出风扇扇片以及轴承。
拆开之后的风扇及轴承、电机。
扇片轴部分已经有长年累月工作留下的磨损痕迹，这种情况即便是上油处理，噪音也不会根除。
上下两个轴承，一捅就掉。
找个牙签或者细棉签粘点酒精、润滑油插进去清理即可。
风扇轴、弹簧、轴承里面随便擦一擦，金属锈、油污灰垢全下来了。
然后给轴承部分上点油就可以了。
清理好显卡GPU的残胶以及PCB的灰垢，准备组装。这时候尴尬再次发生，我手里没有任何显存可用的导热垫了... ...
看了看显存导热垫，没个边上切下来一点凑合凑合也比供电电路裸奔没散热强。
切下来几块，然后铺在供电模块上。
显卡散热器是有单独一块区域直接接触到这几个元件上，并由两颗螺丝固定，因此导热垫稍厚一些也没关系，散热片压实之后即可完全贴合以辅助散热。
然后用螺丝刀把已经变形的散热鳍片拨回原位，尽可能留出足够的通风间隙。
大差不离把，百来块钱的老矿渣就不矫情这些了。
然后是更换信越7921硅脂，淘哥多年来只用某宝极客温控他们家的，原膏不兑油，耐久度max~
大概这么些就够，手指头套在塑料袋上按压即可，一点都不会粘手，这是小诀窍。
熟练的话，一分钟内可以搞定，7921更换这么一次，至少3年内不需要考虑换硅脂的问题。
整备完毕，顺便用除胶喷雾清理了一下散热器外罩部分，看起来似乎也清爽不少~
然后，彩蛋来了
老矿渣就是老矿渣，散热风扇上的原厂保护贴膜还在，太Happy了
人民群众喜闻乐见的撕膜时间~
擦干净撕膜后残留的胶印
是不是又闪亮许多啊哈哈哈哈！
显示输出只有HDMI一个接口，我的显示器是LG 27GL850，原生2560x1440/144Hz的参数，之前还担心只能跑60Hz，那样的话游戏体验会损失不少~毕竟用惯了144Hz高刷
翻出车站以前9块9的HDMI2.1 8K视频线，希望能多多少少給点惊喜
开机，2560x1440/10位色深/100Hz刷新率，Emmmm，聊胜于无吧，虽说没上到144Hz，至少也过百了，游戏也能稍微舒服些（1920x1080可以120Hz，也蛮好）。
GPU-Z参数一览，1206MHz的GPU核心频率，1750MHz的显存频率，太古老了，4年前就已经属于入门矿渣的存在。
室温22C，开机GPU温度38C，稍后测试下看看烤机温度多少。
比较意外的是，这货给到默认122W的功率以及50%的功耗增益范围，也就意味着峰值拉满可以给到近190W的板上功率，驱动面板里可超的范围会很高，比刷BIOS省事儿（毕竟这显卡只有单HDMI输出，万一强刷别的BIOS导致视频输出IO不识别可就芭比Q了）
测试平台还是我的老Ryzen7 5700X，理论上不会拖显卡后腿。
鲁大师的显卡参数一览
鲁大师2560x1440分辨率跑分165821，和昨天8GB的那个RX470D几乎一样，估计后者虽说是砍了10%的SP数量，但显存是8GB 2000MHz的频率，四舍五入也就算打平了。鲁大师显卡测试期间GPU最高温度只有56C、峰值功耗100.8W，这确实让我非常满意，也不枉我花一个小时整备清理它。
3DMark TimeSpy测试得分4181，GPU温度最高仅有61C，峰值功耗105.8W，超出我预期（我觉得至少要68~70C）。
FireStrike Extreme测试得分5589，GPU温度同样只有61C，峰值功耗107.8W，此时我怀疑是不是GPU测温挂了？但是上图3DMark的温度曲线记录图却又明确记录了温度起伏曲线，只能说这版BIOS写得好了哦对了，风扇转速只有24%，才1700多转，声音很安静（那个我维护过的风扇还是有不舒服的噪音，姑且能接受的范围，到彻底坏的时候网上套一对带灯的换上~）
最后来20轮TimeSpy的稳定性压力测试，看下最终的温度、功耗、风扇转速峰值表现。
约半小时左右，压力测试完毕，最终通过率99.6%，车队群友最高测出99.8%的，比他低一些，不过也属于高通过率级别了。测试期间GPU最高温度70C（好在是GPU温感正常）、峰值功耗113.4W、风扇峰值转速1724rpm/24%，对此表现，我还是非常满意的~
这卡也就玩个LOL了，吃鸡没人玩了我也懒得测，多少年没更新了。2560x1440分辨率所有特效拉满、关闭垂直同步，泉水出场427fps~520fps，这个没啥参考价值，下面实际游戏帧数为准吧：
团战期间210~320fps之间，极少情况下掉200fps（我怀疑是否和我截屏有关？）起码是做到2K英雄联盟自由了。
总结
这块179的老矿渣至少进过3~4轮矿山，到我这里算是光荣退役、回归一张显卡应有的角色本位了。目前手头有上个月139买的1250W金牌矿电源一台、机械键盘一套、鼠标N套、散热器N套、闲置机箱一套、闲置固态硬盘N个，再来个板U套装就能攒套整机了，拿来接电视跑个1080p地平线赛车、连NAS看个片还是很轻松的，稍后就去大黄鱼采购一波
