While I don't discount the other answer (it very well could be your hard drive) I would suspect your RAM controller or RAM slot. At first I thought it was Mem, then I thought it was the OS, now I don't really know what could be happening. When watching movies in VLC (mkv, avi, etc) the video becomes pixelated sometimes.Īpplications quit unexpectedly sometimes.ĭid a clean install of OS X Lion, and the issues improved to a certain degree, but still occurs sometimes. Occasionally, my screen becomes "pixelated" in random areas (the image gets distorted as if it was magnified and then pixelated). My Shockwave Flash started crashes constantly a lot under Google Chrome. zip files, after uncompressing them, I sometimes get CRC errors and checksum problems. I installed it and started having problems again: I kept using SL for a few months without any problems (did't bootcamp this time) and then OS X Lion came out. I formatted the whole system and reinstalled Snow Leopard, put back the 8GB RAM and ran the mem test again, and it passed 100% this time. I figured my RAM was faulty, so I switched back to my old 2GB memory that came with the mac, but I got the same error in the mem test. I tried repairing permissions but it seemed to be beyond repair.
The Windows partition worked fine, though. One day, out of nowhere, I got a kernel panic the OS X partition stopped working. It came with SL and I immediately installed BootCamp and upgraded it's memory to two 4GB, low latency Corsair. It's a mid 2010 model with 2.4Ghz and 2GB RAM. You would be buying at a great time as well since 2010 ram is less than half the price when I purchased mine.I bought my mac mini in March 2011. I bought my ram from OWC but, as a previous post said, you can order from those other vendors as well. Only a geek setting up a Mini server farm would worry about that, LOL.
A matched pair of ram should run slightly better than 1+4 or 2+4 but you probably would never notice the difference in real world usage. Even with all that going on activity monitor reports I am usually using somewhere between 5-7 GB so I still have a little cushion but 4 GB would not be enough for me. My Mini gets a fair amount of use from as many as four users logged in at once and all running typical apps such as Safari, Mail, iPhoto and others, not to mention a bit of gaming thrown into the mix. The standard Mini, whether 2010 or 2011, really doesn't have enough ram and the slow hdd hurts it even more. I agree it is a great little machine! IMO it does need a bit more ram for most users.
