i used to have 4 sticks of ram all running at 800mhz, however one of them got damged and i replaced it with a 533 mhz, all models are 1GB.
speed isnt very diffrenet that makes me notice, but i just heard that even if you have 10 sticks of ram at 800mhz and having only 1 of them running at 533, then all of the sticks will down clock their rate and run at 533mhz, is this true? please i need a reply asap.
It will run at the slowest speed of the installed RAM to ensure reliability. You can try to OC it, but it will likely be unstable. You probably won't really notice a real world difference at the slower speed expect maybe in benchmarks. I would just buy more 800mhz ram while it is still around.
