hmm very strange. something is limiting the cards to 5. i have checked the manual of your mobo. its quite good actually. so you must have 2 24pin connections and one 8 pin on to of the mobo for the CPU.
your PSu needs to be connected to ATXPWR1 and to the 8pin CPU ATXPWR3.
then i guess you will need more power for the PCIe slots and below them there are 2 more connections for power.
try powering them also AUXPWR1/2, this will give more juice to the mobo.
and then power all GPUs and see what happens.
I have both AUXPWR 1/2 with individual power connections not shared.
ATXPWR3 has the 8pin connected
ATXPWR1 is connected .
I tried a smaller second psu also yesterday thought it migh have to have two psu connected but that didnt help .
ive actually powered the risers all with 6pin cables took them off sata/molex . all green lights are on.
ive tried different combos of risers and i can’t find any faulty.
theres either a busted arse settings somewhere or the boards faulty even though its new. ?
it shouldnt be busted since it is working with 5 cards. some shitty setting in the BIOS might be the problem
Are you using the big PCIE slot, i saw in youtube some dude avoided it and started with the smaller ones.
have you seen this video https://www.youtube.com/watch?v=hc5BSEFokPg
is it similar to your motherboard?
nar ive stayed off that one , it might be some of these settings maybe where the disable internal graphics is… .
i have =
INTERNAL GRAPHICS = DISABLED
PRIMARY DISPLAY PEG
GTT - 8MB
APERTURE SIZE 256MB
DVMT PRE ALLICATED 32MB
DVMT GRAPHICS MEM - 256M
PAVP ENABLED
TOLUD DYNAMIC
VT-D DISABLED
ABOVE 4GB MMIO DISABLED
RC6 ENABLED
yeah i tried his settings no luck - only difference with this one is i dont have an option for 6x on the mining mode. its either enable or disabled… then below has a bar size which is either enabled or auto. which i have tried both on enabled.
this should be enabled.
got that enabled , i saw the aperture size setting i turned off CSM as it disables it , and went to 2048MB and it worked with 6. put the 7th in. nothing. took that out. now 6 dont work. lol ( wheres that lump hammer )
this aperture size doesnt concern us, its for integrated cards. DO you have some setting , something about Resizable bar , to put it to auto.
yes. its below the enable minning i have set that to auto.
i appreciate your help …
ive contacted biostar hopefully they can help…
would my cpu be an issue? or only 16gb ram.
i doubt that. you have enough RAM and for CPU any CPU can do it.
IF more than three presumably yes and the power form your atx 1, 24 pin connector should control the cpu . The atx 2 psu needs to offer enough power to run the remaining slots. . Good luck!
Elysium, I have the same board. I am currently running 11 gpu’s. I had the same issue of finding out how this board uses power at the beginning, needless to say it was frustrating.
First is to not use the 16x full sized slot. I have a 2400w server psu and bought 6pin to 24 pin cables from paralles miner and hooked up 2 of them to the 24 pin ports and also run 6-pin cables to both Aux 1 and 2. Without all of this I have not had any luck running more than 5 cards. I believe I read somewhere after 5 cards the 2nd 24 pin is needed. I was able to run up to 8 cards with 2x24 pin and had to add the Aux pwr after that.
My bio settings are HD audio off, 4G enabled, Gen 2 on Pcie slots. I run 1 vega 64 flashed to a 56, 4-5700xt and 6-5600xt’s.
Hope this helps
sure does , i found that out i tried connecting the second psu even though the main one was 3000w , as soon as i hooked it up with both it worked ok , minus a dodgy riser. but its going now.
hey, i have same board and i am struggling to run it with more than 5 cards.
can you share your connections diagram. i am running with one server psu and atx psu.
i have 9 1660 super cards

Where you able to figure it out im having the exact same issue
I have the
Tb360-btc pro 2.0
Pentium processor
16 gb ram ddr4
750 psu bronze to power up the board
1300 psu for the cards
7x Asus TUF 1660 super OC
I have both 24 pin connected
Both 6 pin atx are connected
Update bios to the latest version
All my riser are from GPURISER.COM
Both 4g mining options are enabled
All ports are set to 2nd gen
Disable the internal graphic
Primary set to peg
Every time I load the 5th card sometimes it doesn’t post and when it does post and boot correctly some graphics cards go offline
Does anyone know what I’m doing wrong or what I forgot to change
which processor is it ?
Well for me i turned off everything i didnt need on the board , like audio , sata controllers , the CSM needs to be off i turned mine off .
the table bar size under minning = enabled is set to auto
i left the speed on auto - i found setting to gen 1 or 2 or 3 didnt matter
i ended up splitting up the psu units to have equal amounts of cards - i checked each riser one card at a time that they worked , BUT i found that at times dont ask me why i would plug in a card in one slot then add another and wouldnt work , then if i switched the slots it would . >?
also i found loading up too many cables from the psu was causing issues - i dont power any more than 2 risers with the sata molex or 6pin. most actually are on individual cables as i have big power supplies - dont know if that makes a difference.
i dont have the primary set - as i dont have onboard graphics with the cpu i have.
also make sure u dont have any crossed wires as in one psu is powering the card and another is powering the riser like i accidentally did with the birds nest of cables. dont know if it makes a diff but just trying to rule out anything possibly causing grief
i did also clear the cmos. - latest bios
but i have 12 cards now running on it.
take screen shots of ur options u have in the bios and i can cross check with mine ?
I’m going to try all of this because I’m having the fifth card issue.
hey, did you figure the problem out pal? Guess a tonn of people including me has the same issue.
I got 4x 3080, 1x3070 working smoothly in my rig and willing to add some more cards.Powered up with 2x psu(1650). Another 3070 aaaaaand here I’m checking the forum. System starts up and works fine for 3 minutes at most,then It crashes.
