Macbook lags after upgrading from 1.25gb RAM to 2gb

Something's kinda funky with the dual-channel setup then... That's what I'd say, if it only occurs in matching pairs.

I am having the same problem

Hi All,

I was/am having this same issue. At first I only noticed the lag when after I started playing backgammon for awhile. I had the stock 512 RAM. I could tell the whole system lagged by simply using the key commands for application switcher as it was very slow. However, as soon as I quit backgammon the system was responding fine, no lag. I thought this was a problem with lag of memory since it shares. So, I bought new RAM, two 1 GB sticks. Well it was worse from the get go. As with you all, both work fine alone, or with one of the 256MB sticks in either bank. The problem ONLY happens when big bang is opened along with say Safari. If I quit big bang the system returns to normal. This does not, at least to me seem to be a heat issue. Although I haven't monitored heat. I have monitored with activity monitor and nothing is unusual. Please let's keep this going especially if someone finds a solution.

Well, I'm having probably the same problem with my Macbook, standard 512mb installed. I have started a thread on the Apple forum (http://discussions.apple.com/thread.jspa?threadID=563583&tstart=0).

It must have something to the with dual-channel setup, because pulling out one of the RAM pretty much 'solved' the problem.
