How to get 4.5G ram in an iMac G5 iSight

While it does say this on everymac's website for these two computers, getting this memory will allow you to exceed the 2.5G limit for ram,

4 GB Samsung 2Rx4 PC2-6400U-666

I recently purchased a stick off of ebay for $15 and it works well.

Cheers,

i actually did the same, although i'm still waiting on the stick.
how much of a performance boost does it give for you?

Once I got the right stick it is a pretty good performance difference. Scrolling the web is much smoother, visuals etc. I think the OS can really use the extra memory. Let me know how it works for you!

Bummer. You could replace them if you can find them. They're a little tricky to open but finding the parts would be the challenge. Not sure if usedmac.com would have them. Ifixit has a pretty good repair guide.

Neat. It's extremely common that Macs actually work with more memory than Apple specified, since typically the specs they publish were written before bigger sticks of RAM existed. (In this case, 1x4GB sticks of DDR2 weren't common until a few years after the Intel transition.)

Mac OS X loves RAM and web pages are on average 10-20x heavier today than they were in ~2005 when this system was new so it's not super surprising that web workloads benefit a lot.

For most other stuff it'll probably depend on what the exact workload is.
