wow using too much memory

[Catamer]

I'm using two PC right now, the left has an on Radion X1800, the right is using a GX280.
the copies of wow on the x1800 PC run about 750M
the copies of wow on the GX280 pc start out at 750m but when I'm in Dalaran they ramp up to 1.4G.
I've even disabled all of the addons and I still get this 1.4G

I've attached a picture of two of my accounts logged on, the one with low ram is logged on and in the character selection screen.

I only bring this up is because I noticed I was getting lag in Dalaran and I noramally don't. I'm only getting it on one of the PC and it's page swapping, wow is eating up all of my memory.
performace fu doesn't think any of my addons are using much memory.
anyone else see this? is it a video driver problem?

I've even had copies of wow crash, I assume they were out of memory.

Add some more ram?

Dalaran lags for everyone, especially if you have addons that poll other players in terms of gear and achievements and such. Try logging in with no addons, and see what happens?

if your using 6gb or more on the one lagging with a 64 bit os try turning off page file
