I only use Crucial. I got burned with bargain RAM back in the 90s. Never again.

Apologies, I prematurely hit the reply button.

Would you be able to see more from the panic report itself? I haven't had a freeze in a couple weeks, until yesterday. I ran Etre Check immediately after that, and saved the panic report from Console.

I wish there was an easier/quicker way to know if it was the RAM or not. If the RAM wasn't the issue, I could still go weeks without a panic, and I need as much memory as I can get because I work on very large Photoshop files with dozens and dozens of layers, with Illustrator and InDesign as well.

Back in the day I used to use Memtest. Would that or one of the other RAM checkers like TechTool do any good? It would probably take an entire day and I wouldn't be able to work, and of course I'm in the middle of a few deadlines I can't miss.

Thanks so much for your help.

I needed it quickly so I ordered it from Amazon this time. I usually purchase direct from Crucial.

Here's the Amazon link: https://www.amazon.com/gp/product/B008LTBJK2/ref=od_aui_detailpages00?ie=UTF8&ps c=1

Ha. I know that. I'm pretty good with the mechanics—I installed a Core 2 Duo in my old first gen Intel iMac a couple years ago—although I wouldn't want to do that again.

I was just saying that it's been two weeks since I last had a kernel panic and I use my computer all day every day, for work. So I can remove the RAM, sure, but I'll have to wait weeks for another panic, which may or may not come, before. So if there was a quicker way to test my RAM, I'd be all for it.

Would you recommend another source for RAM? I always thought Crucial was the pinnacle of memory for Mac?

Thanks again.

And here's my panic report, just in case.

Thank you sir. I'll look into both. I'm going to send that panic report to the SoftRAID and Little Snitch developers and see what they say. I can live without Little Snitch but not SoftRAID.

Over the weekend I decided to run Memtest. Actually, I ran Rember first but decided to boot into single user mode and run Memtest to be sure. I tested my Crucial ram first, then swapped it for my stock RAM. No errors. I know it's possible for RAM to still be iffy even if Memtest doesn't catch any issues, but that has to be rare, right?

So I took your advice and removed the Crucial RAM and have been running on my meager 8GB of stock RAM for the last 3 days without issue. So far.

So now I play the waiting game.

I'll post an update if/when there is a development.

Thanks again!

I've been running my iMac with only stock RAM for 10 days now without a single hiccup. I'll go another week before I contact Crucial and ask for an exchange. Or should I go with OWC?

By the way, I'm surprised how well it runs with only 8GB of RAM. MacOS' memory management is quite effective.
