Hi Guys,
Looking for a little help. I have a MacBook Pro 13" Early 2011. It's the 2.7 I7 and originally had 4GB of ram.
I bought a 8GB Corsair kit (1333mhz) with apple branding on box, and upgraded the ram myself.
Right away I started getting intermediate graphics glitches when using both the laptop and 27" cinema display at the same time. It's like a quick screen scramble for a brief second and than it goes back to normal. I assumed I got a bad ram kit, and returned it to the store and got a Patriot 8gb kit. Same problem.
It only happens when I use both Cinema & Laptop at the same time. If I close the laptop the cinema display stops glitching.
No glitches if I just use the laptop solo.
It happens more often or more frequently when under heavy load (using flash etc).
If I put the 4GB stock kit in, problem solved but laptop is very slow compared to 8gb kit.
Fresh format of Yosemite 10.10.3 - No changes.
Any suggestions? Bad Graphics Card? 2 Bad kits of Ram? Something else.
Thanks IMORE.
