How many GPUs can I connect to this motherboard?

[Saturnix]

I've read somewhere that this motherboard can hold up to 5 GPUs: http://[Suspicious link removed]/NXTZC4

However, as I asked my reseller if this was true, he replied that it can hold 2 graphic cards on PCI-Express 16x slots in crossfire mode.

Can someone explain me what does it means? This is the same article on the reseller page: http://[Suspicious link removed]/NBjadK, it really looks like the same product to me.

Do I really need crossfire mode? Can I connect 5 GPU do that motherboard, install windows and start mining at full power?

EDIT: since I can't post links, here's the name of the motherboard.

Gigabyte AMD FM2+/FM2 AMP-UP Audio OP-AMP USB DAP-UP UEFI DualBIOS ATX Motherboard GA-G1.Sniper A88X

Thanks for your help!

You have 2 x16 slots and 3 x1 slots. You will need x1 risers for the x1 slots. It should hold 5.

So, those connectors labeled PCIEX1_1, PCIEX1_2 and PCIEX1_3 are meant to be connected to a GPU, right?

If I had 5 of these:

In order to work properly I'd just need 2 of these:

and 3 of these:

Together with a power supply unit, cpu, ram, hdd. Do you think this can work? Or, perhaps, some software problems may arise in using 5 gpu's?

Sorry for sounding like an idiot, but I've never done this before and the most manuals on mining are all like: "oh yeah, just connect some cables, download some shit and press some buttons dude..."

You might power raisers.

This one? Yeah, I was wondering also how to manage the power supply. Do you think 2 GPU draining from the motherboard and 3 from an external PSU can be good? Thanks!

You need 1X riser 3 PCS and 16X riser 2 PCS so you can add you 5 GPUs.
By the way what PSU are you using? Be sure for that also

why not try litecoin cloud mining?

Not to mention the explosion of scrypt hashing power soon to arrive, those calculations are probably very generous.

Check out this video on youtube of some guy building a litecoin rig with similar motherboard... if you haven't assembled a PC before then you could pick up a few tips.

Use powered risers. Also get this motherboard it's cheaper: http://www.microcenter.com/product/382952/970_Extreme4_Socket_AM3_970_ATX_AMD_Motherboard

Because I've concluded the price of a KH/s is destined to exponentially decrease over time. A price of a GPU card is too, but the drop is not exponential.

I've concluded this based exclusively on Bitcoin cloud mining (see https://cex.io/), the situation might be different with litecoins and other scrypt currencies. I will check out the link you sent me, it looks very interesting. Thanks!

I still don't know what PSU to buy, since I don't know which GPU models I'll use and how to correctly compute the required voltage. Thanks for pointing out this problem!

Seems better indeed, thanks! I hope my reseller have this. I cannot import expensive goods from the US without paying, so I need to buy gears inside of the EU. PCI risers cost 9$ on amazon but if you live in the EU prices starts from 12€ ( = 16$) which is insane. Not to mention the powered ones, which I saw for prices starting at 25€.

no problem hope it works out for you mate

If you're interested, you could send the parts to our farm in Oregon and we could assemble and build the rig for you. You would have remote access to it. Check out our website: http://www.myrigspace.com/

check out ebay for cheap risers in eu....

here is an x1 adaptor for £6.99 (shipped from china i think)

don't those riser usually get caught on fire?

no definitly no
