I want to upgrade my 27 imac 3.4 to 16GB, which brand of RAM should I buy? Does brand really matter?
 
Any mainstream brand should be fine - as long as it meets the specs. Crucial/Micron should work for sure, Mushkin, etc.
 
for me, I just stick with Samsung Factory Original. I never had any kernel panics from them all 3 machines, I maxed them out 16gb. I purchased them from OWC.

PS. I did try OWC brand and had a kernel panics, then switched them to Samsung and had no problem since then !
 
I upgraded mine to 12gb using Crucial RAM from Newegg.com with no problems. I do a little 3d compositing and lots of video editing and have found 12gb to be sufficient so far. Its not worth another $100 just for four extra gigs imo. I would go with 12 for now and when prices drop in a year or two keep the 8gb of Crucial, ditch the OE 4gb and add another 2 x 8gb sticks to boost it to 24gb of ram.
 
Brand doesn't matter. Buy it, plug it in, done.
Not quite, you want a reputable brand.

On a then relatively new system, Apple once updated firmware which tightened the specs needed for memory, one of the brands replaced all of their memory that failed with the new firmware under warranty. Not all brands will do this. So to repeat, buy a known reputable brand for memory.

Transcend vs. Crucial, which one is better?

Most brands don't make their own memory. They have other companies do it for them. Several "brands" are all made within the same fabs. So in the regard brand is irrelevant.

Warranty coverage is up to the actual company selling it so sure, there could be some difference there. Most offer 5 year to lifetime warranties.

The ram in my imac is made in a fab that also makes ram for OCZ, Kingston and others.
 
Transcend vs. Crucial, which one is better?
Look up issues people had with the memory, especially any issues with warranty service. For all you know the ram from both brands is made by the same manufacturer. That is why I used the term "brand" in my previous post as you don't go to the manufacturer of the memory for warranty claims (unless that happens to also be the brand of memory you bought).
 
Transcend vs. Crucial, which one is better?

Crucial is one of the best Ram brand available. Pick it up now.


Why?

And FWIW, adding 8 gigs for a total of 12 is a far, far better cost vs total ram.
Why did you question every upgrade people want to do?

We all want to spend money on upgrade, so we do. That's it.

As there's no 3gb of ram memory available, so, to get 12gb you will need to broke the dual channel (if it is dual), or slow down the system if it is triple and you are using 2x4gb + 2x2gb. If the system is dual channel and you are going to use 2x4gb + 2x2gb, then the slow down will be imperceptible, but it will slow down.
 
Sorry in advance for the newbie question: How do you tell which RAM is correct for the imac? Is any laptop RAM usable?
 
Guess I'll get the crucial 4 gb x 2 listed above from newegg.

But I was curious to see if there was any 8gb x 2 available for the new imac yet. I couldn't find any on the crucial website.
