Review on OWC SO DIMM PC3 14900 Upgrade OWC1867DDR3S4GB by Domonic Roberts

Works but not as I expected based on other reviews. I haven't noticed any significant improvement adding this to the 8GB I already have installed on my iMac. It seems to work. * ****Update****** My iMac started freezing and restarting, Apple replaced the motherboard but the problem persists. Memory removed as Apple thinks the modules are bad and the crashes have stopped, contacted OWC via Revain to see if I can get a replacement. Will update when I know more.
