whats causing this issue sometimes i see somethings get very very grainy and distorted
It'd be nice if we new more about when it happens and your system specs.
It happens on mail an safari. 256 GB SSD MBP late 2011. 8 gb ram
If that's not stock RAM, have you tried putting the original Apple memory back in?
Its not the ram nor the ssd because both are non stock
How do you know it isn't the RAM?
The GPU in the 13" MBP uses system memory as VRAM. If you're seeing graphical glitches and you've got 3rd party RAM in there, the first thing to try is reinstalling the OEM RAM.
Because its a good brand just because something isnt made by apple or OEM doesnt mean its a bad product
No, it doesn't mean it's a bad product. Your Mac may just not work well with it.
I'm just asking if you've TRIED your OEM RAM, and you have yet to answer the question. Alternatively, you could run Apple hardware test and see if it reports any errors. You may have to enable the extended test, looping, and let it run overnight. I have a feeling it'll report a memory problem.
This is part of troubleshooting.
No didnt try oem yet this started recently. Ill do a ahwt what do i have to hold down?
You press and hold down the D key when the computer chimes.
Another thought: Have you tried a PRAM and SMC reset? I had some strange graphical issues on an older MBP and they were temporarily fixed by resetting the PRAM or SMC, I don't remember which. It turns out the computer had a bad GPU, and eventually the logic board was replaced.
Cant do aht at all never could even when stock
I'm not sure how to help with that, my 13" MBP is an older model that included AHT on the 2nd disc. Are there any EFI updates that you haven't installed?
If you have warranty, you may want to take this into an Apple store or call AppleCare for service. They'll likely have you reinstall your stock HDD and RAM though.
Just try putting stock RAMs back in and reset PRAM.
If stock RAM runs fine, then its your aftermarket's RAM is faulty.
