Help the experts to explain what this is？

It was purchased from the online mall. I only know that it seems to be a PCIE converter, but I can't find any other parameters except the card.

It looks similar to PCIe Analyzer interposer cards that I worked with in the past. But this is NVIDIA branded, and I doubt they have their own analyzers (most of the places I've seen these at work with LeCroy units).

It might be some sort of a piece of their in-house test equipment as well.

Thanks,bro,I checked its interface online again. It looks like OCulink-8 Lane, maybe sff-8611?

It might indeed be an analyzer part. Or just a PCIe to PCIe+OcuLink adapter.

It has that silver chip on it, with all the traces around it, can you clean it up and upload a picture of what is written on it?

It might help if you cleaned the thermal paste off the chip...

Yes,after time i clean it.The chip name is PEX 88048,from Broadcom.

The chip is a pretty standard PCIe switch. So it seems like it is a slot splitter that takes a PCIe slot and splits it to a slot (top) and OcuLink connectors (on the "back").

This is what im thinking
"You though you were getting a cheap gpu and you thought wrong."

Hey bro,I wiped it clean and you can see it now.

Haha LMAO,At first I thought it was a graphics card, and then I noticed that the top of it was different from other graphics cards, and I realized that this card is not simple.

I have a question now, its manufacturer is nVidia, but I have the impression that nvidia does not seem to have produced this kind of card, so is it an ES product from nVidia?
This chip also has a relatively late factory date (it seems to be a PCIE4.0 switch chip produced by Broadcom in 2021), and I suspect that this may be an unmarketed product.
Then I bought it from a second-hand trading website for less than $15, LMAO

I took some more detailed pictures and now upload them.

It is likely to be an in-house testing card of some sort. I doubt it is a "product" per se.

I also think so, but if it can be used normally, I may find a big bargain. The price of this card is very expensive, as long as it is normal. It's a pity that there are no desktops around now, only laptops.

On Taobao (Chinese online marketplace) it's coined as

pex88048 免主板拆分 PCIe40 直通扩展卡pl​

Probably a 4x U.2 port adapter without the need for bifurcation.
Your variant is probably missing it's cooler fans.
