Hi guys, wonder if you can help.

I have 16GB RAM (2X8GB) in my Imac and although its not too sluggish I thought I would buy another pair of 8GB to make it extra zippy and total 32GB.

I used the checker on the crucial website and then purchased from Amazon as I had a voucher to use.

7 weeks later and my Imac suddenly experienced kernel errors and eventually wouldn't even let me get to the login screen. I unplugged each USB device with no change until I unplugged the new RAM and it seems its ok now.

Crucial result stated I required
  • CT2K8G3S160BM
From Amazon I purchased
  • CT2KIT102464BF160B
Are these the same thing? as every other criteria matches.

The crucial suggestion does not exactly match any on Amazon and a lot of the reviews used that RAM for the same spec/age/size machine.

https://www.amazon.co.uk/Crucial-CT2KIT102464BF160B-PC3L-12800-SODIMM-204-Pin/dp/B007B5S52C/ref=pd_lpo_sbs_147_t_0?_encoding=UTF8&psc=1&refRID=B63DE0DKZ0XVSVB0A2T9

I'm just wondering whether I have got unlucky with a rare faulty product as I know how well regarded crucial is.

Thanks in advance,

Abi

I only buy from OWC or Crucial direct. Trust Amazon as far as I could kick them.

Crucial memory for your iMac is CXT2K8G3S160BM so I would suggest Amazon's is wrong and causing the problems.

OP:

What kind of DRIVE is inside the 2013 iMac?

IF it's a platter-based hard drive, THAT'S why the iMac "sluggish".
Not so much the RAM.

Add an EXTERNAL USB3 SSD, and set it up to become the boot drive.
The iMac will then run MUCH faster.

It has a 1TB Fusion drive inside.

I am a photographer and store all of my photos on an external 4TB drive and have a 6TB time machine.

I wouldn't say it was sluggish but had an Amazon voucher to use so thought extra RAM would make it quicker.
