imac 27 late 2013 3.5 i7 can i upgrade 32 gb ram

Hope other people keep pushing it and I may try again in the future. I got farther than I thought I would and getting the Imac to even boot with it was neat. Maybe with 10.16 coming later this year there will be another bootrom update and maybe these High capacity chips will work in older 2013 Imacs. There may be more compatibility with the Haswell Cpu's, Don't know till we try? This iMac model has a PCIe slot in addition to the HDD SATA connector, where a SSD can be installed. It would be interesting to try the same chip 16gb DDR3L 1600 chip on a 2014 or mid 2015 Imac. One thing I haven't tried is running it with Win10, and at this point I won't since I've played with this enough and these chips are going back in the mail before I brick my wife's Imac, but if somebody were to run Win10 and see if it's a MacOs limitation or Hardware compatibility that would be another clue. At 51C, but that shouldn't be effecting the system. I checked the Dimm temp's and the 16gb chips do run a bit hotter than the 8gb chips. So at some point there is a degree of the CPU recognizing the Large ram chips but it's not able read from them entirely correct.

I tried running it with 10.15.4 and it's still unstable. Ports and connectivity come via 4 USB 3.0 ports, 2 Thunderbolt ports, 1 Gigabit Ethernet, 802.11a/b/g/n/ac compatible and Bluetooth 4.0.Unfortunately today after a few hours I got Kernel panics with it in 10.14.6. The sleek aluminum housing of these models tapers to a slim 5mm edge around the screen perimeter with greater girth in the center of the unit. This model has a 27' 2560x1440 LED 16:9 widescreen IPS display with a monolithic anti-glare glass laminated LCD panel.

This model sports dedicated Graphics thanks to an NVIDIA GeForce GTX 775M graphics processor including 2GB of GDDR5 graphics memory.īase configuration comes with 4 memory slots with 8GB DDR3-1600 (PC3-12800) SDRAM installed as a pair of 4GB SODIMMs (with 2 slots empty) and a 5400 RPM 1TB hard drive, a 'FaceTime HD' webcam and stereo speakers with no optical drive.

This BTO 'Build to Order' iMac Core i7 3.5GHz 27-Inch (Late 2013) is powered by a 22 nm Haswell Quad Core 3.5GHz Intel 'Core i7' 4771 processor with a 8MB shared level 3 cache.
