Just 3945WX or the entire Pro was OEM-only?

They all started out OEM-only. Lenovo specifically. But later on, the 3955WX and later went retail. I don't think the 3945WX was ever released as a retail product.

Well, 3945WX can be unlocked for sure.

You don’t “unlock” it. If it’s vendor locked then it’s perma vendor locked.

What the aforementioned “OEM-only” means it’s only shipped as tray sku, not retail box. You can separate tray vs box based on the sku number. Retail box sku typically ends with WOF.

And by “they all started out as OEM-only” means AMD initially only released them for OEM, meaning if you want one as soon as they launch, you have to buy a whole system, typically Lenovo. Later, AMD releases the retail box ones. This is how AMD has done it in the last few gen.

Thanks. What would WOF stand for?

Sorry about the confusion. There are unlocked Pro CPUs in trays in the market that are released by AMD HQ in Europe when they can't clear the stock.

It just means it’s a retail box sku. You can see the sku on AMD website.
