So, I know PCIe x16 is ideal for mining but what about PCIe x8 or x1? Can you use them? Are they efficient enough or should I be looking for dual/tripple/quad PCIe x16?
What about these PCIe extenders? How do they work?
Also, I heard something about ASIC for mining. What is ASIC and how do they work?

Thanks, that actually didn't answer anything. I can definitely look this up and do research though. Sorry to bother you.

x1 is fine for mining. PCI-extenders just use a ribbon cable to allow you to raise your card from the board.
Application-specific integrated circuits, or ASICS, would be much more energy efficient for mining. As far as I know no one has done this yet. Field programmable gated arrays, or FPGAs, have been used. These also are highly efficient but can be prohibitively expensive... though cheaper than an ASIC.

x1 slots are fine for mining and you will see no loss in hash speed from doing so.

That's cool, I didn't realize you could mine with anything other than x16. Should open up a lot of cheaper motherboards for me.
What about cards, I think you can but wanted to check - can you have a 5870 and a 4870 on the same motherboard and crossfired together?

No need to crossfire they should work fine separately but if using windows you may need dummy vga or dvi plugs for any card not plugged into a monitor

There's one guy who has done asics, name of artforz. Also, have heard rumblings of someone that wanted technical expertise and wanted to spend some money. Search is your friend

Question - PCIe 1x and 4x will work fine, right? Looking at getting a cheap machine with 1 x16 slot and 1 x4 slot. This is the board: From left to right, I think, x4, x1, x16 Just wanted to make sure that this WOULD, in fact, work. I was reading this thread: https://forum.bitcoin.org/index.php?topic=14910.0;allAbout someone funding an ASIC setup. Paying attention to that one.

Is there any type of a PCIe splitter that'd make one slot into 2? I forget the thread but I thought someone mentioned something like that.

Homework: Write a 1000 word essay on what google and wikipedia are and how to find information for the very specific term "asic" on them. Then explain in 2 sentences what an ASIC is. At least dont be that lazy as asking this here, please.

Are you sure 1x is OK for mining? No card seems like it'd fit that slot. Do you mean 4x?

You will need to use a 1x extender and file down the connector to allow a 16x card to fit.

No, you are better of not putting the cards into the slots.
* Get pci-e 1x -> 16x cables. * Raise the cards, use all slows
=> Max number of cards, good airflow and cooling, most cost efficient.

Yes but in the configuration of that mobo, the 4x and 16x would be the best two to use. If I get extenders, I'd have no way to mount them in the case. I don't have a whole lot of extra room to build risers, etc either.
