Bad RAM twice
on July 26, 2010
I bought this RAM as an upgrade to my MacBook Pro. The RAM seemed good for a few days, but I soon discovered it was the source of my Mac's Kernel Panics that started shortly after installing the RAM. It seemed to be associated with filling a certain area of the RAM, because my machine would work fine, until I had a lot of memory-intensive programs running. Often the problem would happen when putting the MacBook to sleep. At last, the RAM just totally died -- I got the 3 longs beeps of death when I turned my Mac on. What a sinking feeling that is! I put the original RAM back and, fortunately my Mac seemed okay. I returned the RAM to Amazon for a replacement. Amazon was wonderful -- they even sent me the replacement RAM before I had returned the product to them. The new RAM also seemed to be fine for a few days, maybe almost a week. Then I started getting Kernel Panics again. At that point, I decided I would just live with 4G of RAM and forget trying to upgrade to 8G. Amazon was wonderful again about returning the product, this time for a full refund. I questioned myself, that maybe I installed the RAM wrong. But then I answer myself that every time I put the original RAM back everything is fine. So I'm pretty sure that either: out of each batch of 2 RAM chips, at least one was bad each time, or, the Mac OSX Snow Leopard does not handle 8G RAM. Whatever the case, I am sure that I install the Kingston RAM, I get Kernel Panics, I put the original RAM back and the Kernel Panics go away.
You may be suspicious about my report and I don't blame you. I am surprised at this behavior myself since I have been installing my own RAM in PCs for 2 decades and I cannot think of a single instance where the new RAM was bad; until this experience, that is.
