PCI-E v1.1 1x slot?

[secularflesh]

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 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!

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.

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.

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 )...

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.

extension cable with extra power

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.
