Cutting a PCI-E X1 slot?

post #1 of 13
Thread Starter 
Hey, I have an old P4 socket 478 Dell system that I want to test my 5870 in. I just don't want to kill the board. Is it safe for me to cut off the small ending piece of the X1 slot and then put my X16 5870 in to make sure it turns on? Or will it kill the board. Thanks!

You can do that no problem just be careful when you cut it so you won't damage the mobo PCB ....

Thanks, I will wait for a few more replies before I start cutting.

Wait wth? You can put PCIE cards in the PCI x1 slot? Im so doing this...

EDIT: Oh wait nvmd i remember seeing this. You can also get PCI slot risers if you don't want to cut it up. (I wouldnt bother though for a old crappy board)

Can you also Xfire using this method?

You can put cards in that slot no problem (infact I've done it before for folding machines) but don't expect any stellar performance (folding is great as it doesnt really need the bandwidth) in xfire.....

Oh wait pcie 1x slot are there even pci 1x slots? :/

You lose performance. A lot of performance. I only recommend it maybe if you've got an old rig with an AGP slot and a PCI-E X1 and you have a PCIex16 card laying around you want to use.

There is no PCI 1x slot.

On the other hand any PCI-E card you can fit in a PCI-E slot should work in that slot.

A PCI-E 1x slot can accept a 16x cars if it's an open-ended slot, or if you cut/file off the back of the slot.

Performance loss in gaming is significant, but there are many uses (most OpenCL and CUDA apps) where there is next to no perceptible difference.

Should work just fine. Just don't bend any pins. Make sure your psu can handle the 5870 also.

Im thinking to do this for a server board I have, old with a 8x slot, AND 8x length.

Could you get a good up close pic when you're done, and what you finally end up using to do it? I was thinking a needle nose pliers would break it right out.
