help help help please rx470

[amd1361]

hi there
i have just bought 2xSapphire rx470 4gb nitro plus( one of them is hynix and the other one is elpaid)and i am going to start gpu mining.
my rig specifications:
mb: Gigabyte z170x ud3 (latest bios)
cpu:g4400
ram:: 2x4gb g.skill tridentz
Psu: 1050 watt platinum
Last night i put both cards into pci express slots ,flashed the moded bios to boost the hashrate and installed win10 , everything was ok, even i mined (for testing purpose) some ETC.
Today i decided to use my riser cables (deepcool 16x16) to start mining but to my surprise when i connected the cables, i noticed that in GPUZ the PIXLE FILLRATE and TEXTURE FILLRATE were reported unknown. as a result my system became unstable and even msi afterburners didn't detect the cards.
I have 3 riser cables and all of them were the same (i tested the cables individually) even  i tested one of my 1x16 riser cables  windows didn't detect anything as if i didn't connect the gpu to motherboard.
is it possible that all the cables are faulty and twi of them (16x16) show the same symptoms?
what do you think i should do?
thanks

I think you should start playing games.

I think you already started a thread here:

https://bitcointalk.org/index.php?topic=1733286.msg17344817#msg17344817

It is not nice to start multiple threads on the same thing.  Secondly, I would suggest that with your limited experience to stop flashing ROMs and start with the basics.  I have tried to help you but you want to ignore the easy solution and continue trying.  So here is a little help: I would suggest you know what you are doing to the BIOS before manipulating it.  If you say "I am using PolarisBiosEditor"  I and many others will reply that you probably have no idea what you are doing.

So here-
1- Flash your bios back to normal and use the driver you want to use 16.12

OR

1 - Use the poorly modded ROM and
     A - Clean Install WIndows
     B - Use Driver 16.11 or earlier.

Otherwise please be more specific with your problem

Thank you for your suggestions
So I have to take your advice and first I should flash my cards back to the original ROMs.but I have failed to find the right original ROMs for both sapphire rx470 4g hynix and elpadi.
Can u please help me how I can find them cause i am scared of bricking my GPUs. Is the ROM the same for both models? And is atiwinflash the only tool for flashing?
After flashing them I will install reason 16.11 to see if it works or not
Thanks
