I wouldn't worry about that at all.
This is why I always tell people to keep their Apple RAM when they upgrade. RAM is easily replaceable, and it's aupposed to be replaceable. just pop the original RAM back in.
As long as your problem isn't being caused by the third party RAM, which is why keeping Apple RAM is important, as you can put it back, and see if the problems persist, then Apple won't know, or care.
Of course, the one problem I had with a Mac was way back in 1992 with my Quadra 950. Everything was fine until I upgraded the RAM past a certain point. That machine had 16 SIMM slots. I went past the first 8, and had problems with the system recognizing the extra RAM. I got all sorts of crazy numbers.
It turned out that one of the SIMM slots was bad, and Apple replaced the mobo under warrantee, two weeks short of the warrantee running out!
I hadn't returned the computer to them, but to Tekserve, who didn't care what memory was inside. They checked it out, and got the mobo from Apple.
Unless you have a GOOD repair place that does work for Apple, you must return your machine to them with their memory.
A few people have complained over the years that Apple removed their third party memory because it either was defective, causing the problem, or didn't meet Apple's specs, causing the problem, and charged them for Apple memory AND repair costs.
So, keep your Apple RAM, but don't be afraid to upgrade with third party memory from a known, well regarded vendor, and NEVER buy cheap memory from some non Apple memory supplier.
As long as the memory is spec'd to work in the machine, it will be fine. just follow the instructions.
