Do not buy, He is a scammer, took away money and blocked me telegram.

Update : I just purchased ASUS Prime B250M-K motherboard. It has 1xPCIE16x and 2xPCIE1x slots. I disabled CSM, enabled 4G decoding, disabled every possible extra items in bios like serial port, IOAPI entries etc, it only allows 5 GPUs to work properly, rest 3 GPU gets detected but it ends up with Code12 error in device description ( Out of PCIE lanes ).
However here is a weird thing, when I uninstall a GPU in device manage, then it uninstalls all GPU from device manage as being in same class, now after uninstallation, all 8 GPUs shows up as "VGA Video Controller". Now I right click on one of these items, and select "update drivers" then it again installs all 8 GPUS but this time with 7 of them working!!!
Now, if I reboot the PC goes back to OS again, it again shows only 5 of them working and 3 goes with CODE12. I am trying like for 18hours with diff. things. Any clue guys?

p.s. I tried ethOS, it detects all 8 GPUS and all works without any issues.

Okey I got it working on my MSI Z170A Gaming M5 motherboard. Got all 8 GPUs detected and working on Windows 10 1709. Did bios update and I got "Above 4g Decoding" option. Set it to enabled, and set PCIE speed to gen2.
Popped 1to4 risers to each PCIEx16 slot, plugged 4 GPUS in each. You don't even need UEFI , my ssd had generic MBR partition and it worked fine.
So, still confused if it will work on other chipset. Currently Z170 motherboard is costlier than current gen. Is there anyone who can confirm this working on entry level B250M motherboards?

I have 6x1070 1x1080 and 1x1080ti. OS is not related at all as it doesnt even pass bios screen.

Yea I figured it lately that x58 can only handle up to 4 GPUs.
I have a Gigabyte B85M-Gaming 3 motherboard, it works fine with 6 GPUs, but with 8 GPUs it just fails to even load into bios. That even with 4 GPUs plugged into PCIE1x slot via extender! so this means chipset is limiting its usage to 6 GPUs.

Hi,

I recently bought PCIE 1 to 4 expansion cards from below.

However, on my old system with chipset X58 and also on new H97 chipset, only maximum 6 GPUs working. I tried every possible settings in BIOS but no luck getting more than 6 GPUs working on any of these chipset.
I am now thinking to move towards newer chipset like B250. If I purchase lower end mobo. with 1x PCIE 16 and 1x PCIE1x slot , will it work? Do newer chipset support 8 GPUs? I am not talking about special mining motherboard, just a regular one.

oh okey, thanks for the info

I have 60 coins in my wallet with POS mining enabled, but it says "no mature coins found" in bottom POS icon. what does that mean?

EDIT : nm, figured it out
Thanks for the tip. I cant mine skein with ccminer though, give me "retrying in 30sec..." error on startup. tried 4 diff. ccminers...any clue?

Thanks! I learned a lot from 5 posts which were made in reply to my query. For now i found that nist5 and lyra2v2 is currently most profitable. correct me if i m wrong.

Thanks for the advice. I recently tried ccminer 1.8.3 mod4 version. Do You suggest any other miner?I prefer a GUI one until I get to understand all command line versions.

I am new to mining. I own a ASUS Strix 1080Ti which I want to give a try for mining. I searched this forum for what to mine and I found most recent recommendations about zcash. On other side I also checked on nicehash for hassle free mining.
What do you guys suggest?
