Will the new 21.5" iMac support 16GB of RAM?

Question

I just bought the 21.5" mid 2011 iMac (the $1,499) model. I also just purchased 16GB RAM from OWC to replace the 4GB that came with it. I thought I had read that the 21.5" model can support up to 16GB, but then read this on the iMac spec page: "Configurable to 8GB (all models) or 16GB (select models), only at the Apple Online Store." Can I install 16GB on my machine (4GB per slot, times 4)? I'm worried it won't work because I've seen reference of 8 and 16 on Apple's site as the max.

Answer 1

The spec page says this, so my SWAG is it'll support 16 GB:
Memory
More memory (RAM) increases performance and enables your computer to perform faster and better. Choose additional 1333MHz DDR3 memory for your iMac.
The more memory your computer has, the more programs you can run simultaneously, and the better performance you get from your computer.
Select the standard memory configuration to support day-to-day tasks such as email, word processing, and web browsing as well as more complex tasks such as editing photos, creating illustrations, and building presentations.
Upgrade your memory to enjoy greater performance for more intensive computing tasks, such as video editing and DVD authoring
Your iMac uses one of the fastest memory technologies available today — 1333MHz, Double Data Rate (DDR3), synchronous dynamic random-access memory (SDRAM) — ensuring that the processor is constantly fed with data without wasting clock cycles.
4GB 1333MHz DDR3 SDRAM - 2x2GB
8GB 1333MHz DDR3 SDRAM - 2x4GB [Add $200.00]
16GB 1333MHz DDR3 SDRAM - 4x4GB [Add $600.00]
