Cheapest memory for iMac?

Crucial RAM is the best!
I have 4GB in my iMac and it was worth every penny.

 

Penny Wise and Pound Foolish.

Go with the Crucial.

You have a pricey, high performance computer so possibly saving 6 pounds on something as critical as memory might not be the best way to go

 

exactly.

You just spent $1600 and now you are trying to save $5.

 

Hi CBG,
never buy the cheapest in anything (and I hope you don't treat your own work with the same attitude...).

 

It is not, the speeds are different which will make the stock RAM function at the lower speed as well.

 

The specs on the Amazon module (which is a Crucial module) appear to be the same as the stuff you get when you search for iMac-specific kit, but it's a different part number. I'd give Crucial a call and ask them if they confirm it's OK for your iMac (don't see why it wouldn't be). On the Crucial site that module is the same price as the iMac-specific module, so I would guess it's just cheaper as it's from Amazon. You may get it quicker direct from Crucial, though.

On the plus side, as it's actually Amazon not a marketplace seller, you should be fine returning it if there is a problem.

 

They're both 1333 and CL9 - I wasn't aware there was anything else to worry about. Whats the difference?

 

You are correct! Reading comp fail on my part, confused the 10600 and the 1333.

 

Phew - haven't paid much attention to RAM specs for a while so thought there was something new I didn't know about!

 

Crucial for around $65 worked perfectly in my HP 6910p to reach 4GB from the stock 2GB. I took the advice to get all 4 rather than just 2 since I had 2 slots with 1 each.

And their CrucialScan utility is pretty good at picking what's compatible.
