This is the 21.5" Retina 4K iMac Logic Board for the mid 2017 model only. This generation of iMac used the Kaby Lake range of processors. This logic board has a 3.6GHz Intel Quad Core i7 Processor. There are two ram slots on the rear of the logic board which can take up to 32GB of PC4-19200 (2400MHz) DDR4 SO-DIMM modules. (Non-user accessible.) This logic board has an integrated graphics card, AMD Radeon Pro 560 (BF XLA) with 4GB of dedicated GDDR5 VRAM. This is the first range of iMac to have two Thunderbolt 3 (USB-C) ports capable of transferring data up to 40Gbps.
Please note the following two important pieces of information regarding this logic board:
• This listing is for the SSD version, which means this logic board has a 8.0 GT/s NVMe PCIe x4 port located on the rear of the logic board for a single modular SSD and is also capable of having a single 2.5" hard drive fitted to the machine.
• This logic board is only compatible with the Retina 4K models of the mid 2017 and is not interchangeable with the non-retina version.
This is a highly static-sensitive device and replacement should not be attempted without suitable experience and anti-static precautions. If you remove the heat sink from the logic board, the seal must be re-made adequately when the new board is fitted to ensure the iMac does not overheat. Thermal paste is available from the Tools section.
Provided with 3month guarantee. No refund will be given for logic boards damaged during fitting.
