And you're not using NoteCaddy with hundreds of custom notes/definitions?
Then you really don't need more RAM.
No. I do use it, but just the version that comes with HEM2. No customizing..... YET. I am still getting used to HEM2, so IDK how much I will - in the future - want to involve note caddy. But for now I just use the default NC, and not all that much so far.
