Defective RAM can cause all sorts of problems. If you're suffering from frequent crashes, freezes, reboots, or Blue Screens of Death, a bad RAM chip could be the cause of your travails. I recently upgraded my system means I upgraded all the motherboard and ram etc and graphics card was same then I faced freezes, display errors, crashes and choppy graphics+artifacts, in case I replaced my old HD 4650 with new HD 5570 and problem didn't resolve so i ran MemTest and got 18 errors in my one RAM stick and 2 errors in my other RAM sticks so please answer the following question:- 1.
2011 machine can hold up to 16GB of RAM, 2-8GB sticks.

It's almost 2014 now, that's about 3 years. OS X Lions need 4GB+ easily, programs are being bloated.
If the machine was heavily used, the keyboard and trackpad worn, or if it's a 13', then go for the third party 8GB and stick it in yourself and make do.
If it's a 15' or 17' and not heavily used, or if your needs will exceed 8GB RAM, or it has a SSD already, and you have been babying the heck out of it, then perhaps the $300 is worth it.
Average lifespan of a laptop is about 3-4 years, more with considerable care and wear and tear placed on external devices.
So it's nearly 3 down now and X amount to go, depending how well you treated and took care of it if it's worth spending $300 for another 3 years or not.
You can always try the 8GB and likely that will be enough, or if it doesn't work, return the RAM or sell it on eBay and get a new machine (newer machines need newer RAM specs usually, but not in all cases)

Bad Ram Slot Symptoms Problems
My Early 2011 is like brand new almost, it still has the factory smell a little.

The keyboard perhaps had 100 characters typed, it's covered by the thin foam packaging and the trackpad wasn't used at all hardly. Superdrive was only used a few times.
My machine with your problem would make a ideal candidate for a $300 fix, as it's the last 17' Apple made and still kicks arse so it's worth a lot used still as people want it for Snow Leopard and it can be upgraded to 10.9+
But if yours is a 13' well that's a less powerful machine, no dedicated graphics and it's hot, so it's not worth as much for a $300 repair as it's closer to the 3 year lifespan and obsolence than a 15' or 17' 2011 model.
