Asrock H97 anniversary

Or

Gigabyte GA-Z270-Gaming K3, not cheap but tested to work with 6 cards...and can be used later on gaming.

Check if you can snatch those used
MSI Z97 Gaming 5
Asus Z87-PRO

I had Asrock H97 anniversary board and it's really good. It's the same socket as H81 Pro Btc and it have 6 PCIe connectors too so see if you can find it in your country and you should be good to go there

biostar tb85

or you could go amd, and get a gigabyte 990fx ud3 and a $15 athlon/phenom ii

i'm going to try the MSI Gaming Z97 GAMING 5 LGA 1150 Intel Z97 I read this works and it is easy to find the other ones can be tough to find because lots of this stuff is sold out

biostar also just relesed BTC  board couple days ago

BIOSTAR TB250-BTC

MSI Z97 is little expensive and Asus Z87-PRO support only 3-4 graphic cards only . am i right ?

This one should be good enough for you, since it a LG 1156 ,price should be cheap and has lots of PCI express, actually I see you can use up to 6 Gpu here. Better give a look yourself.

i have the asrock h81 pro btc never been used i got it all set up but due to money issues i never completed it

what country are you from?

Pakistan

PM me

just get a MOBO with at least x1 PCIE slots and you are done.

which one would be good  ?
1- biostar tb85
2- Asrock h81 pro btc

Asrock H81 if you can get it, or the Biostar if you cant get Asrock.

Can anyone tell me please what settings to use on Gigabyte GA-Z270-Gaming K3 in order to work with 6 GPUs ?
I tried and when I plug 6th card it would not start, not even to bios, looks like there is not enough power to PCI-e slots, and there must be some bios settings.
Any ideeas ? I am trying for hours :/

Thanks.

haha

nice DIG, the post is almost a year old.
it could be interesting to have an updated list of good MOBO that does 7+ gpu

Helped a friend setup a 6x GPU rig with this board. Worked perfect right off the bat.

Did you need to plug that extra power connector in top of the PCI slots ? I don't have that :/

isn't the graphics card much more important than which mb you use for mining?   (Unless you need something like 6 slots for cards, or something unusual like that.)

has 6xVGA slot:
-Gigabyte H110-D3A LGA 1150
-Biostar TB250-BTC
-MSI Z170A
-MSI Z270 Gaming M7
-Asus Prime Z270-P
- Asus Prime H270-PLUS

hopefully, available in your country

Yes you are correct. The Motherboard is *generally* only a factor for how *many* cards you can run.

I disagree, the wrong motherboard can be a pain in terms of hashing stability speed, overall stability, setup time, etc.
Some motherboards fail to keep all cards connected, some need special drivers in windows, some need you to disable the onboard GPU and plug the monitor cable to one of the cards, etc.
Some motherboards like ASUS B250 mining expert has 18/19 GPU slots but you need to mix certain Nvidia and certain AMD cards in certain slots, annoying.

Replying to my own question in case someone bumps into same issue:
The Gigabyte GA-Z270-Gaming K3 will only start with 6 cards if you
 - update bios from their site but not with latest version but a special "mining" bios version for this card, that is found in a different area of the site (mining mini-site).
 - disable onboard GPU and make it start with PCI 1 by default
 - install OS and only then connect the other 5 cards (6 total).
 - with 6 cards you will only get video signal once it boots into windows 10 and you cannot "see" the bios/startup with 6 cards ?!

It has 2x 4-pin MOLEX plugs for PCI-E power and we did plug them both in.

good motheboard is ASUS PRIME Z270-P .

Where is it verified to run 6 gpus?  I can only get it to boot with 6 if I disable igpu. And even then it reboots once you start m8n8ng.
