My Msi R9 295x2's have a problem when oc'd :/

[melibond]

Hi i have two Msi R9 295x2's and made the radiators in push pull config with two Noctua NF-F12 IPPC 3000pwm on each radiators an i managed to get 60c on all cards at full hard stress for 40minutes,then i managed to get 1109 on my core clock and a whoping 6.8ghz on my memory clock while still maintaining a temperature lower than 70c (68c max to be precise) and totally reduced all the stuttering i had on every game i ever played,but there is only one problem,sometimes i have thos white lines and some white blocks appear while gaming.
I tried other overclocking settings wich fitted perfect but still had those white thingies.
So,what could be the problem,did i do something wrong ?
I also put the thingy to +50% (150%)
Just so you don't ask me about that 😛.
Well,if you know what the problem is than please reply and thanks a lot 😀

you should decrease the OC to your memory

I'll try lowering and testing slowly and i it works i'll pick your answer as the best 😀
I personally thought of that but if i go too down with the memory clock then it wouldn't be much of an overclock anymore :/
But nontheless i'll try the best combination possible
Thanks a lot

What are your system specs? You may simply not have enough power. You can always try raising your voltage as well.

Don't worry,i got a Corsair AX1500i and my whole system had once a peak of 1100w of use max,so yeah,don't worry,power is perfectly fine.
It also has 80+Titanium.
