迈络思cx6 dx ocp3 0升级200G、PCIE4 0 Unleash 200G Beast on a Budget! Upgrading OCP3.0 Mellanox CX6-DX

OCP3.0迈络思cx6-dx升级200G、PCIE4.0
今天这期视频，帮一位粉丝朋友升级了2张Facebook定制版本OCP3.0接口cx6-dx，
网卡型号是CX623435M，P/N是MCX623435MC-ADAE-FB。
这个估计是目前市面上最便宜的迈络思200G网卡，
此网卡是Facebook定制带固件锁且固件加密，是不能直接刷迈络思官网最新版本固件，
需要专门工具才能升级，需要邮寄升级，无法远程升级固件。
升级以后可以通过mlxfwmanager在线更新迈络思英伟达最新版本网卡固件
ocp3.0是服务器上的网卡，台式PCI使用，需要OCP3.0转接PCIEx16卡， 此类卡由于使用麻烦，
但耐不住此类卡白菜的价格，很多兄弟蠢蠢欲动，
除非个人主板有支持OCP3.0网卡接口，否则不推荐折腾这款200G OCP3.0网卡
1、Facebook版本OCP3.0网卡固件属于Facebook定制，也有固件锁， 是不能直接刷迈络思官网最新版本固件，否则很容易变砖。
2、OCP3.0转接PCIE转接卡很贵，目前大概要300左右
3、此网卡发热巨大，服务器主板有OCP3.0插槽，可以借助暴力风扇散热， 但普通PC中使用，必须改散热，要不然分分钟115度自动掉卡保护
4、OCP转PCIE固定也不牢固，很容易松动

Unleash 200G Beast on a Budget! Upgrading Facebook's Custom OCP3.0 Mellanox CX6-DX to PCIe 4.0! 🔥
Hey tech enthusiasts! In this video, we tackle an epic upgrade: transforming 2x Facebook-customized OCP3.0 Mellanox CX6-DX NICs (Model: CX623435M, P/N: MCX623435MC-ADAE-FB) into 200G PCIe 4.0 monsters! 🚀
Why You Should Care?
💸 Cheapest 200G NIC on the Market! These Facebook-locked cards are dirt-cheap but come with firmware encryption—no direct updates from NVIDIA/Mellanox! We show you how to safely unlock and upgrade them.

🛠️ Hidden Challenges:
1️⃣ Firmware Jailbreak Required! Avoid bricking your card—custom tools and physical shipping are needed for upgrades.
2️⃣ OCP3.0 to PCIe Adapter Hell: Adapters cost ~$40 (¥300) and are notoriously unstable. Not for the faint-hearted!
3️⃣ Meltdown Warning! These cards run HOT (115°C+!). Server-grade cooling or DIY mods are MUST-HAVES for PC use.
4️⃣ Compatibility Nightmare: Only recommended if your motherboard has native OCP3.0 support.
After Upgrade Perks:
✅ Unlock mlxfwmanager for future NVIDIA firmware updates!
✅ Achieve 200G speeds with PCIe 4.0 bandwidth!
💡 Pro Tips:
Not for Newbies! This is a hardcore DIY project—ideal for server tinkerers or budget-driven homelab warriors.
