16X PCI Express Video card used in a 4X PCI Express Slot?

Just wondering if this will work but at 4X speed?

The card info is:  Encore VGA GeFORCE 7300GT nVIDIA PCIe / PCI Express Graphics / Video Card, 256MB RAM, 128-Bit, ENVGA

Yes, normally it will work well. In your case, there's almost no difference in performance between 4x and 16x slot. 7300GT is not a strong card, so a 4x bandwith for it is more than enough. Tested on my mainboard which have 2  pciex16 (one run at 16x and one at 4x) and there's almost no diference with 8600GT
If it physically fits in the slot [and doesn't ground out on the end that sticks out] it will work fine but at 4x speed.
Some 1x, 4x, 8x slots actually are missing the back 'wall' to allow installing longer cards easily.

The end of PCI-e cards near the back plate [back of case] has all the power and control circuits and is the same on all PCI-e cards.
The rest of the card is for the data only and it's simply the same circuit repeated once for each 'x' the card is.
The added 'x's just increase bandwidth [speed].
Being up/down interchangeable like that is REQUIRED by the PCI-e specification so all PCI-e cards are REQUIRED to work in all PCI-e slots, and all PCI-e slots are REQUIRED to work with all PCI-e cards.
- The problem is that is about 'the electrical' and it assumes they physically fit in the slot.
- There is no requirement for motherboards manufacturers to layout boards so any card will 'physically' fit into any slot.
yes, it works, but it will be running on 4x not 16x, as your slot only works on 4x
Thanks for the update r2r
- That's what I said...
