Mislabeled Radeon Pro VII Card | Generated by AI
You’re right to push back with the listing’s description. Let me re‑examine this carefully.
The advertisement claims:
“AMD MI50显卡，16G显存，带ECC芯片……鲁大师跑分40W左右……插上即用” (implying display out) and you say it explicitly mentions Mini‑DP.
Officially, the AMD Radeon Instinct MI50 is a headless compute accelerator (no display outputs). The card with the same Vega 20 GPU, 16 GB HBM2, ECC, and multiple Mini‑DisplayPort outputs is the AMD Radeon Pro VII. The two are often confused in the second‑hand market because they share the same die, but the Pro VII has a blower fan and 6× Mini‑DP, while the MI50 is a passive server card with zero video connectors.
So what’s actually being sold here? It’s almost certainly a mislabeled Radeon Pro VII (or a card that was converted, but that’s far less likely). The mention of “插上即用” and Mini‑DP, combined with “鲁大师跑分40W” (a typical Pro VII score), makes it clear: this is a display‑capable workstation card.
If the card is indeed a Radeon Pro VII (or equivalent with Mini‑DP), the previous “critical – no display” issue disappears
You’ll get a video signal normally. However, other potential problems remain, and some new ones need attention:
- Driver & Software Compatibility (minor but real)
- A real MI50 requires ROCm (Linux) and has no Windows display driver.
- A Pro VII uses standard Radeon Pro / Adrenalin drivers (Windows & Linux) and works as a normal GPU for displays, gaming, and compute.
- If the seller flashed a Pro VII with an MI50 vBIOS to sell it as a compute card, you might face driver confusion. Check GPU‑Z: it should report “Radeon Pro VII” and show 6 Mini‑DP ports under the Graphics Card tab. If it says “MI50” but has ports, the vBIOS has been cross‑flashed—you may need to flash it back to a Pro VII BIOS for reliable Windows operation.
- Cooling & Temperature (the 90°C stress test)
- The official Pro VII has a blower‑style cooler; 90°C after 10 minutes of stress is high but within its thermal limit (max ~110°C hotspot). Still, it suggests the card may be dusty, have dried paste, or run in a low‑airflow case.
- The DeepCool CH270 is a vertical case with decent airflow, but if the card is a passive MI50 (no fan) that was modded with a Mini‑DP, 90°C is disastrous—you’d need to strap a fan directly to it.
- Since the ad says “插上即用” and gives a temperature, it’s likely active‑cooled. 90°C is borderline; I’d expect throttling or loud fan noise.

The CPU cooler still may not support AM4 The BUBALUS Frost 360A listing emphasizes AM5, not AM4. You must confirm the box includes an AM4 bracket and backplate. Without it, the cooler is useless. Simply ask the seller or check the package contents.
- RAM & SSD are very overpriced
- 32 GB DDR4‑3200 for ¥979 is ~double the normal price. You can get the same spec for ¥400–450. This eats budget that could go toward a better power supply or a CPU upgrade.
- A 1 TB PCIe 4.0 NVMe SSD for ¥899 is also high; good 1 TB drives (e.g., Solidigm P44 Pro, WD SN770) often cost ¥500–600.
- PSU quality concern The Thermalright TR‑KG750 is a budget Gold unit. It’s probably fine, but for a Vega‑based 16 GB card (which can spike >300 W) and a Ryzen 5 5600, I’d prefer a slightly better known unit from a tier‑list regular (e.g., DeepCool, Cooler Master). However, this is not a deal‑breaker if budget is tight.
Verdict: Is this setup usable?
Yes, if:
- You verify the GPU is a Radeon Pro VII (or at least has working Mini‑DP outputs and a fan) and you can install normal drivers.
- You source an AM4 mounting kit for the cooler.
- You consider swapping the RAM and SSD to sensibly priced alternatives, saving ~¥500+.
No, if:
- The card turns out to be a real MI50 with no video out (despite the ad), and you’re left with no display.
- The card is a cross‑flashed Pro VII with driver issues you can’t resolve easily.
My recommendation: Before buying, ask the seller for a clear photo of the I/O bracket (showing the Mini‑DP ports) and a GPU‑Z screenshot. If they match a Radeon Pro VII, you’re good to go—just fix the cooler and memory pricing. If they refuse or the card looks passive with no fan and only a single suspicious Mini‑DP, walk away.
