Ya I do need to send it in for service. It is the GPU amd issue and I do not want to provide them with an excuse not to fix it.
The RAM is user replaceable with your model, as stated in the manual, take a copy with you, either as PDF or in whatever format you like.
When changing RAM, you are nowhere near the GPU, the GPU is even on the other side.
And if you still have the receipt for the new RAM, you can probably show them, that the period between the RAM upgrade and the GPU failure is too long to have anything to do with each other.
And if you decide to go with the new RAM to the Apple gals, keep the RAM models documented, as they might replace it with the original RAM and then give you that back and forget about your new RAM.
Good luck.
PS: I once had an iBook with a faulty logic board. I replaced the 512 MB RAM module with a 1 GB module before that and there was no problem fixing the logic board, since it was a known problem, as is the 2011 GPU issue. They will not be so cheap to blame you for the damage, as they will lose a customer that way. If they fix it, you will more likely to be staying with Apple and your future computer purchases, unless you have had a ****** experience not yet.
Sorry, am a bit high on painkillers.
