关于如何判断自己显卡是矿卡
作者：破晓前最亮的光
请签收你的美女一手自用显卡：
问：矿卡翻新自用，可以直接水洗吗？
答：可以，随意洗。
不但背板可以水洗、风扇可以水洗、连PCB板子都可以水洗。
不需要浸泡，直接拿自来水冲，图的就是一个快。
问：PCB板可以用刷子刷吗？
答：可以。洗都洗了不得安排个spa？
洗洁精+刷子/魔力擦，只要不是钢丝球硬搓，其它的都好说。
不管来的时候有多脏
哪怕吃了半辈子沙的：
带不明毛团的：
Spa完都给它整得明明白白：
收藏这一篇保姆教程，操作的时候胆大心细，烘干得足够彻底，矿卡翻新其实很简单。
让人失望的RTX4060Ti：
最近看了一眼RTX4060Ti的性能，别说脚踢RTX3070了，“堪比”RTX3060Ti G6X的性能，甚至偶有被老卡反杀的情况。
再看一眼RTX40系列显卡的整体价格。
我突然发现之前买的几百块钱的矿卡更香了。
新卡竟然会倒逼RTX3080矿卡涨价，只能叹一句：孩子你让为父很失望。
矿卡虽香，但购之有道。
作为特殊的商品，矿卡一样有一套避免掉坑里的方法。
这篇是关于矿卡翻新家庭版操作实战，涵盖【购前选择】、【购后翻新】的操作。
结合我多张矿卡翻新的经验，不敢说照做后可以避免所有的坑，但十拿九稳是没问题的。
所以，记得点收藏。
购买前 ·需要确认：
① 矿卡可能会用一段时间就boom，也可能继续正常服役5.6年。
② 矿卡可能会存在各种各样的隐患，也可能没什么问题。
③ 有些老型号的卡已经服役过几轮矿潮。
④ 非锁算力的型号，和G6X等型号，其它二手默认矿卡。
⑤ 道理我都懂，但是矿卡便宜啊。
购买前 ·锁定自己的性能需求：
仅供参考，例如CS:GO和永劫无间，同分辨率同显卡下，二者的帧数会差很多。
显卡质保相关：
① 质保起算时间按照发票时间计算。没有发票按照显卡出厂时间计算。
② 显卡售后分为支持个人送保和不支持个人送保两种。
③ 部分品牌，对A卡和N卡的产品线的质保政策不同。
④ 人为损坏不支持保修，譬如摔断PCB板的边角。
⑤ 部分品牌不支持矿卡送保，或缩短矿卡质保周期。
购买前 ·主流 NVIDIA显卡保修政策：
魔龙和超龙的矿卡卖不上价也是有原因的，如果过保了就无所谓了。
购买前 ·主流 AMD显卡保修政策：
（瀚铠最近又恢复了个人送保）
购买前 · 询问卖家
① 生产日期，是否过保。
② 有没有包装，保修贴有没有破损（维修过）
③ 3D MARK跑分成绩（降电压和频率会降低分数）
④ 3D MARK压力测试通过率和核心温度（要截图）
⑤ 风扇有无异响，接口是否全部能用（很重要）
基本是以下这些：
购买前 · 准备清洁工具
如果确定要换硅脂垫和硅脂，硅脂垫可以搜到比较便宜的，硅脂我用的是超频三的EX90
购买后 · 测试
购买后 · 清洁
蓝宝石 RX5700XT 超白金PRO
老板也直接说是矿卡（不说我也看出来了）：
入手价格：700+
软件测试一切正常，到手后简单擦了一下：
可以看到散热器有外框有一些磨损的痕迹，这种肯定算外观8成新及以下了：
主要观察的是散热器，只要散热器鳍片不出现锈蚀，对于家庭清洁来说，都不是问题。
保修贴已破，此前至少被打开过一次，矿卡老板才不会那么闲给你特地清灰，所以99%是维修过的。
矿卡显存坏了重新焊一个上去是很常见的。
挡片有轻微的锈蚀，不过不严重。
遇到严重锈蚀的可以（虽然不推荐买锈蚀的）:
① 拆下来用除锈剂喷一下，用海绵打磨
② 打磨用的磨砂膏+高目数砂纸
这次主要清洁的是散热器、风扇和PCB。
前两者会影响显卡散热效果，后者属于治疗强迫症，拆都拆了，为什么不顺便一起清洗？
风扇螺丝锈了，而且有明显的拆修痕迹
拆解：
螺丝刀工具一定要齐全，拆解到一半进行不下去，又没有其他备用显卡，导致又要把风扇装回去继续用会很尴尬。
鉴定为脏，但不是很脏。
蓝宝石的风扇供电接口设计我很喜欢，风如果挂了，方便更换新风扇（矿主：你很懂啊。）
背后的灰是一定要清理干净的：
蚊子的干尸：
图最中间的这颗螺丝很难拆：
好消息：
好消息，这张超白金打开后不是很脏；
坏消息，因为上一任主人拆开来维修时顺便清理过。
一波操作猛如虎
烘干一定要长，不要怕麻烦，手持吹风机我是顺手拍的，实际是非手持状态下吹了很久：
此处要注意1：
刷的时候不要用力，如要PCB恢复光亮，建议再用魔力擦海绵擦一遍。
风扇、散热器外壳等塑料件，一定要用魔力擦清洁，很窄的缝隙需要用软毛刷。
此处要注意2：
清洁完PCB后一定要马上甩干，然后立刻开始吹干（有工业烘干机更好）。
吹风机不要靠太近/长时间贴着吹，最大风力+最大温度
吹干顺序：DP/HDMI显卡接口（4分钟） 供电接口（4分钟）把PCB板表面水分吹干（5分钟） 对着 核心吹（20分钟）
清洁后：
就说这对比明不明显吧：
清清爽爽，强迫症直接出院：
粘贴硅脂垫&涂抹硅脂：
在扣掉老化的硅脂垫之前，一定要把硅脂垫的位置都拍下来留作备用，另外要留意显卡背板上也有硅脂垫：
买硅脂垫的时候要提前确认硅脂垫的厚度，太厚螺丝可能拧不上
硅脂我用了超频三的EX90，散装买的，散热性能表现良好。
另外，市面上的硅脂的导热效率，其实90%以上都是虚标的，也不知道是谁开了个坏头，导致大家一起在虚标的路上狂奔。
一旦开启了虚标模式，虚标的数据只会越来越离谱。此时每一个厂家都是虚标的既得利益者，同时它们也是虚标的受害者，就是这么矛盾。
数字看看就好，实测换上EX90后比刚到手低8摄氏度，考虑到风扇清洁等影响，实际可能有4~6摄氏度，对此我表示满意。
重新安装：
至此，家庭版翻新基本完成
用磨砂膏和高目砂纸打磨的挡板：焕然一新
实测数据：
2022年12月购买并测试，测试时室温17，开侧板，减少机箱影响：
FURMARK 烤机最高温度在63。
3DMARK 压力测试实际GPU温度在62。
可以说在62下，风扇转得不是很勤快，如果手动风扇全开，温度在52。
TSE，DX12模拟2K分辨率：
写在最后：
① 买矿卡须谨慎。
② 彻底清洁需要一定的耐心，如果积灰不影响使用，简单擦灰即可，无需拆解。
③ 如果不是现在RTX40性价比不行，考虑买矿卡的人群至少去掉一半。
④ 我认为最值的矿卡，依次是一百多的RX588，七百多的RX5700XT和一千四百多的RTX3060Ti。

@终虞叶18650416106# 怎样鉴别矿卡,求详细 -
#汲剑俊3238： 淘宝上卖的很便宜的二手卡就绝大多数是矿卡,例如500多的7850
@终虞叶18650416106# 买了个2手显卡铭瑄7770,有没有可能是矿卡呀?怎么判断 -
#汲剑俊3238： 如果显卡背面的显卡供电区域电路板发黄(长期高负载高温烤的)就很有可能是矿卡.
@终虞叶18650416106# 请问这个显卡是矿卡吗? -
#汲剑俊3238： 有一定概率是矿卡,因为它的核心已经比较黄.
@终虞叶18650416106# 矿卡和普通显卡区别 -
#汲剑俊3238： 卡本身都是一样的,但是矿卡等于是全时间满负载使用,寿命会有问题.
@终虞叶18650416106# 580显卡是否是刷的怎么分辨? -
#汲剑俊3238： 区分580是不是刷的方法如下:查看外观、拆解散热器、使用显卡测历备仿试软件.1、查看外观 看收到的显卡背板、散热与原厂的外观是否一致.不过有些商家会将坏掉的RX580散热换在RX470上刷RX580,所以,这个方法不能100%确认....
@终虞叶18650416106# 如何辨别在网上购买的二手电脑有问题,或矿卡 -
#汲剑俊3238： 1 看评价,重点看差评,到底是卖家还是买家问题 2 看商品页面描述的保修时间,运费承担情况 3 买好运费险 4 买来测试真伪,进行一定的负载压力测试,除软件外,可以跑几天的大型游戏,一般折腾一周不出问题,以后短时间出问题的概率就很低了 最后你得懂硬件,有些东西即使不是坏的,也是性能很差的东西,典型的如低频多核洋垃圾至强CPU骗小白.
