Hello, probably you have to buy a new one graphics cards.
check your pci risers, dont connect them with sata, only 4pin or 6pin
First of all, confirm the input voltage into the assembly, is it in line with the specification?
Study manuals if available to ensure you assemble correctly.Test and check each device
at a time to by elimination to confirm its functionality.This way you should detect where
the fault is coming from.

by testing one card at a time you can confirm or deny that the problem is not your GPU's . if both cards don't crash testing one at a time on stock clocks then you can try running both cards at stock clocks as the next test.
so after few hours maybe around 12 hours my second card is working normal and hashing21.800 stable no crashing
does that mean i had bad riser ??
im gonna try and connect my gpu to a new riser and see or should i keep one directly to the motherboard and the other one to a riser... ?
Yea sounds like you have bad risers. Because you only have 2 gpus you could do it that way with one on the motherboard if u want to, should work. But yea get some new risers and see what happends.

So after 24 hours the first give me 0 crashes in stock setting now im trying the second card incase there'ssomething wrong with card i hope not
and its hashing 21.800 mh\s
and its hashing 21.800 mh\s
Maybe you got faulty GPU. I got 2 gpus which were not able to be flashed or overclocked... And the 3rd one came without BIOS (Sapphire nitro+). So I sent it back to the RMA and i am waiting for the results now .. 
Hashrate on the pool will always fluctuate but look for the average 6/12/24 hours.
so its been around 12hours with no crashes
but on the mining pool it shows unstable hashrate
i guess im gonna wait till 24 hours then im gonna put the other card just to make sure everything is working fine

im not sure if that means unstable or nothing to worry about coz i wasnt at home and im just checking through the pool
but right now its doing 21.800 stock setting

I'm assuming that the "-50" that you put in settings is -50mv voltage to the core? Try getting rid of that. Most cards can handle that but occasionally one card can't and it will cause the whole rig to go down.
Also, you can leave Hardwareinfo64 running and look to see if you're getting memory errors - if you are back off on the memory overclocks.

Now im running 1 card directly to the motherboard stock setting lets see if its gonna crash...
Question will that happen if i was running 2 gpu??
Have you checked what memory the cards have (samsung, hynix?), and have the correct bios flash?
Yeah i checked and did bios flash and i reflashed it bk to original now the rig mining on stock setting getting 21 3 hours runing no crashes untill now ill wait untill im bk from work and keep you guys updated If I had to guess, your issue was probably aggressive overclocking. Do you remember what your settings were?
1200, 1950 -50 mv 60% fan
Hynix memory

what is the model of PSU that you have ?
no crashes untill now but im gonna keep it for few hours, yesterday it stayed stable for 3 hours then it crashed i have corsair cx750 W
what is the model of PSU that you have ?
if it crashes, change the GPU with your other card and retest under the same conditions, stock settings use the same pcie connector(s) from your PSU, you want nothing else to change other than changing the GPU.
yes only one GPU at a time and test it on stock clocks, connected directly to the x16 slot in your mobo
plugged 1 card directly into the motherboard its doing 21.900 mh\s stock setting ill wait and see if its gonna crash
ill wait for a while and update you guys thx for the help
