Title: PCI only rig (not PCI-E) - possible to mine? Post by: Jcw188 on March 29, 2013, 03:18:30 PM Hi I have access to several desktops with PCI slots only. I looked at the list of video cards here (https://en.bitcoin.it/wiki/Mining_Hardware_Comparison?vm=r&s=1#Nvidia) and it seems like only PCI-E or higher are possible to mine on.
Does anyone know if there are any PCI video cards that I can mine on, or are there PCI/PCI-E converters available? Thanks! Title: Re: PCI only rig (not PCI-E) - possible to mine? Post by: Nancarrow on March 29, 2013, 03:35:56 PM AFAIK there aren't any PCI cards, or if there are they're extremely ancient and no good for mining.
There *are* PCI->PCIe adapters, but I have had bad luck and/or stupidity with the ones I tried (my first rig has two PCI slots, I use one for the wireless NIC and didn't want the other to go to waste). I ordered an unpowered one, worked fine for about 4 months and then all of a sudden my rig wasn't detecting any card in that slot anymore. Saw no obvious signs of damage on the adapter, the riser or the card. Then I got an adapter with a molex power thingy from Cablesaurus but I couldn't get that to work at all, so I ordered another unpowered adapter (I think they were both on Ebay from a Chinese outfit called Sintech) and that one lasted two months before, again, apparently just ceasing to work with no obvious signs of damage.

To be clear, I can buy the converter and then buy a PCI-E video card and it should work in the PCI slot (with the converter attached)? (realizing you said you didn't have much luck with it...)

As far as I'm aware StarTech PCI-E to PCI adapters are to run old PCI cards in new PCI-E slots, not the other way around. Title: Re: PCI only rig (not PCI-E) - possible to mine?

This is what I got: http://www.pc-adapter.net/products/321.html Though like I said, bought 2, lasted ~4 and 2 months respectively. You may also want to try first putting the converter in the PCI slot, then putting one of these powered risers in the converter: http://cablesaurus.com/PCIe-x16-Extender-Cable-w-Molex-Connector *Then* connect the PCI-E video card to the powered riser. That little white molex connector has to be plugged into a PSU somehow. But like I say, couldn't get that to work at all :'( whilst at least with an unpowered riser, I got some work out of it.
