HELP TO CONNECT 6 GRAPHIC CARDS

[Amph]

what is the point to under clock ?  you get less speed

i overclock it but not at max, don't wanna kill my gpus
running 6 x 380's at1080 on 1200w
and 5x 380's on 1000w

the real point for it is to maintain the hot level at minimum, you have fresh and more cooled card with it, it's good to underclock in the summer, in the winter you can avoid it

but this only cut it if the ratio is the same between consumption and earning, not always the case

For the AMD R9 390, we can use the 1250 MHz instead of the 1500 MHz. The hashing speed is not affected.

If you do not overclock to over 1120 MHz in the core, the memory speed can be 1200 MHz, using 98% of memory controller.

Oh then I should buy and try with the mobo BTC-PRO and buy USB Power Riser,

What about the Dummy Plug ? No one say something.

Oh thx for your answer you help much ! Maybe its just about the mobo. Thx all

That can be mobo fault.

just to say the ASRock B85 Anniversary, is not good for 6 gpu's, 5 is ok but not six

the computer is not stable i always have trouble with it, got crash at lease 1 time a week (not overclocking probleme)
computer freeze or half freeze , you can acces some stuff but got error's or program won't load and some are freeze)

specially not compatible with 6 x r9 380
not able to get in windows after you install the last driver, if you do, you get hard disk error's and windows service what crashed
i tried win7 the worst one never got in windows after 6 graphics drivers loaded, and win 10

it s actually the last pci-e connector ho makes the troubles (is it share with the sata's connector?)

i switched the gpu's with my other ring, 2x r9380 + 4x r9 270, it s working under win 10   but it s not stable
sometime after crash i m not able to boot again, i have to restart  the computer with the last one unpluged, and reboot again with the last one pluged
