Thanks all, I know all about 1x extenders, etc.  Just wanted to know of if the PCI-E version mattered.

I tried searching for "PCI-E 1.1" but as you can imagine the results weren't stellar.

be careful to not exceed the pci-e spec, that says pci-e devices on x1 slots are not allowed to pull more than 25W.  Cheesy
extension cable with extra power

I know you can mine with a 1x slot, but does the version matter?  Does PCI-E 1.1 work just as well as 2.0+ when using a 1x slot?

Thinking of using an old board in a mining system.

It can matter if you want use a HD 5xxx+ card, some older Intel chipsets (Intel 945 family and older) have problems with those cards. I saw only new BIOS patches from ASRock for those (~4 years) old boards. Should work on a newer Intel chipset, or with other chipset vendors products (like AMD Tongue)...

The 1x slot are enough for mining, but 99% chance, that you will need a PCIe extension cable, because most PCIe 1x slots are "closed", usually only a 1x card fits in physically.

For mining purposes you won't notice any difference, I use PCI-E 1x, for some of my systems and they do the same hashing as my PCI-E 16x.

It shouldn't make any difference.  PCI Express 1.1 lanes were 250MB/s.  In 2.0 that was doubled.  But with bitcoin mining you're using almost no bandwidth.  I doubt you'll see any difference.

You can always give it a try - put the GPU in the x16 slot and mine, then try the same thing via the x1 slot.  Compare and see if there is any difference.

Good luck!
