I'm researching a memory upgrade for a 2018 Mac Mini (in advance of purchase). I thinking to buy it configured with the base 8GB and upgrade it to 32GB with aftermarket memory modules, at a savings of about 50% ($300) from the $600 extra of ordering it with 32GB.
The spec as far as DDR4 2666 MHz 260-pin SODIMM seems quite clear, but I haven't been able to find a CAS latency value for the RAM I'll find installed in the Mac mini. I wanted to get memory with a matching latency or perhaps something below. I'm not looking for extra performance; I just want to make sure it's as compatible as possible and not slow it down.
Here's the conundrum:
- The Kingston and Crucial memory selectors both lead to CL=19 modules for Mac Mini 2018.
- An offhand mention in an Amazon review stated that CAS latency for memory on iMac 2017 was CL=17.
- Kingston offers HyperX modules (targeted toward PC gaming) that have CL=14 at a comparable price to the CL=19 modules.
So I was hoping to find an authoritative source for what the original-equipment CAS latency was for the Mac Mini. If it's CL=19 I'll go with the Kingston-recommended modules, but if it were CL=17 I'd probably go for the HyperX modules. Unfortunately, an hour of Googling around has met with no joy on that count.
Is there some place I can find that spec online or does someone just happen to know and could share that?
