Anyone tried x1 to x16 converters for PCI Express?

They look like they'd let you run a FirePro on them, when mounted with a low profile mount.

The reviews are 100%. For $27 + S/H, might as well try. Not losing much if doesn't help - just time and S/H costs

Looks like ebay has an interesting variation on this idea.

Wonder how that'd work?

1. Need to figure out a way how to mount the card for adequate air flow
2. Seller is reputable, but it ships from China, so you have the shipping time and Customs charges to deal with
3. You can't return it if you're unhappy.
4. Price + shipping +Customs charges > New Egg solution.

There seems to be something missing here.

These gadgets seem to only give you the conversion/connection from a x1 bus to a x16 bus. But if a video card is designed to use a x16 bus, wouldn't it need to take signals from all the other lanes/points?

Or the motherboard circuit automatically detects that there are only lanes for x1 active, and only sends info through those lanes. If so, wouldn't be like cramping 16-times of information through a 1-size pipe? Is this adequate for video application?

Something gotta give. I don't understand it enough.

Yeah, it's enough. Even an old x1 slot can handle 500MB/sec. That's more than enough for trading. (I once put a meter on my internet bandwidth.. during the trading session, traffic slowed to as low as 27Kps. Not a typo... "K".)

x1 cards work just as well as x16 cards for trading.

These are especially built for Bitcoin-miners (or currently: Litecoin and alts). The Molex is to feed additional 12 volt to prevent burning the mainboard (Bitcoin-mining video-cards can take 18 Amps x 12V = 220 Watt or more).

Most miners use 4 of these Risers with 4x AMP-7950 cards.

Do you mean AMD? Not AMP? I couldn't find any card with AMP.

The Radeon 7950's burn a lot of power, I'd have to agree, if that is the card you are talking about. I'm surprised they could even make such a card work on a x1 slot.

Oops..sorry. Yes indeed AMD

And yes, Mining-software only needs a x1 slot (there are Mainboards who can handle 6x 7950's).
