hello,
Is the extra x16 slot on this motherboard (which I believe only runs at 4x?) compatible with any other PCI express cards? Like x1 x4 etc?

Thanks!

You can put any size PCI-E card in a PCI-E x16 slot.
You can put a 1x in a 4x size, etc, etc, etc.
Will there be no issues at all?
So can I place, for example, a PCI-express x1 network card in that x16 slot, and not experience any difficulties?
From what I understand, it is possible to install any PCI express card, in any PCI express slot, as long as it is at least the same size or larger?
As long as the slot is the same size or longer it will work, no problems. But if the port is only a certain speed, say... 16x size, 4x speed, then it will run at the 4x speed.
Ok, thanks for your help dude.
I believe it works the other way too - you can put a 8800Ultra in a 1x slot, and it will work in theory - obviously it doesn't have the electrical means to be given anywhere close to full bandwidth, but it should work in theory.
Yeah, but that can be hacked off, no problem
I'm fairly sure I've read that PCIe is theoretically backwards compatible, as well as forwards. Backwards and forwards isn't right, but you know what I mean.
I may have simply misread this mind, but I'm sure I've read that if you hacked off the pins up to the 1x connections it will work fine, just slower.
I might give this a go sometime if I come across an old graphics card.
As well as finding your attitude rather poor, you're also wrong.
http://www.interfacebus.com/Design_C...I_Express.html - check out the pinout tables - the power only goes through the first 22 keys (11 on each side), which is common to all PCIe cards, regardless of whether it's a 1x, a 4x, a 8x or a 16x physical card.
http://www.tkdan.com/SC420/ - check this out to see a guide of doing it in a Dell SC420.
If you trust TomsHardware, they also did a test by blocking off pins on a 16x card, and benchies to compare losing bandwidth. You can grab that here.
I agree it's not something you'll likely have to do, and certainly won't want to, but there's nothing at all to stop it working. The theory works in practice.

At no point did I say it would fit. I said it would work in theory. The point wasn't that you would tape your card up and stick it in a 16x slot, the point was that a 16x would work in a 1x, 4x or 8x slot - this was proof that it would, as was the other link. It obviously has uses (that Dell SC420 being a good example). You said it wouldn't work, I was correcting you.
And all you have to do is melt or cut a tiny little piece in the PCIe bracket for the card to fit. It's hardly hacking it to bits.
