I also know i5 & i7 are not officially supported on my board. I cleaned what I could during the SSD surgery but there is room for more by removing MOAR.įirst of all, I think I duly did my researches but this is a plug & play swap, right? No funny business like EPROM flashing or macOS patching.

simply scares me.īut on the other hand, I could officially max out the specs for a 2009 machine! The thrills! The excitement! Not to mention giving a good cleaning inside, renew the thermal paste, change the CR2032 battery (what is it used for anyway?). And removing that infrared receiver behind the front Apple logo. Especially all those cables, I have this crunching feeling that I could snap something that sat there undisturbed for 13 years. Honestly, I watched a couple videos and read the official Apple Technical Guide about removing the logic board and I feel I might be pushing my luck a little bit. I already had the best (for the time) option for the GPU so the only thing left (for staying in the official in-period specs) is to swap out my Intel Core 2 Duo 3,06 GHz (model E7600) for a Core 2 Duo 3,33 GHz (E8600): 3 MB cache vs 6 MB cache and around 10-15% gains in performance (maybe?). I had 8 GB of RAM and yesterday I maxed it out with four 4 GB Crucial DDR3 modules. Results were great, honestly feels like a new computer. I then watched some tutorials, did some research and realised I could do this and upgraded it with a fantastic OWC Mercury Electra 1 TB SSD kit. I knew the end was nigh for my beloved iMac 27' 10,1. It all begun when my factory Seagate Barracuda started clicking.
