I tried to make the memory of iMac to 32GB. I left whether there is a use or not.


It seems to be able to do it for a long time already, but apparently I can make my iMac27(mid 2011), memory to 32GB.

So I bought two of these to make it 32GB!

I bought two of these. I spent a lot of money again.

The way to do it is exactly the same as when I changed to 16GB before.

But still, memory is getting cheaper and cheaper. Even though it is not yet two years, I was surprised that the memory of 8GB x 2 is the price which is close to the memory of 4GB x 2 (although it says, the difference of almost 2,000 Yen).

Now, I don’t know if I’ll ever use 32GB indeed, but it’s kind of a relief (laughs).

Fortunately, I’ve been playing with Hadoop and Mahout for a while now, so I increased the heap size as much as I could and tried to run it.

I’m using all this memory and I still have room to spare!

(There is no point in using hadoop on a single PC with such high specs, though…)
