Hello all

I installed 2 x 256MB 133Mhz Ram in a G4 400Mhz AGP (the ones that still have 4Ram slots).

There were already 2 x 64MB ram... so now there is 640MB of Ram.

Prob is, its started going loopy.

Things are crashing, Applications say that files are missing... lock-ups, etc.

I booted off of TechTool 3.01 and ran tests. It said that Ram tests failed. It didnt say WHICH failed, but that there were certain tests (11111000000, and a couple others), that didnt give good results.

Apple System Profiler shows that they are fast , 222cas. The original 64MB ram is 222, and the other 64 is 322.

I've told the guy to take one stick out at a time (of the new Ram) and see how it goes.. if there are more crashes, etc.

Could it be the Ram that is causing for files to be missing (apparently)? And the apps crashing?

The first 24hours, everything was perfect. Nothing wrong, not a single crash.. I burned CDs, photoshopped, played games, etc. I dont recall installing anything new.

MacOS 9.1 with everything up to date.

Thanks for any feedback on what I can do.

I would not be surprised if Apps crashing were a direct result of problematic RAM. However, I think that missing files MAY be indirectly related. If the computer crashed, the drive might have been damaged (has happened to me, unfortuanately) which is why there might be missing file errors. As you said, taking out RAM will help determine which problems are solely the ram's fault and which problems are a result of damage the ram MAY have caused. I also think that all the ram that has just been installed should be taken out and after that, run the computer for a few days. Gradually introduce the ram you think is problematic to see what exactly is causing a problem. Try everything. *True story: I was trying to install extra ram in my computer and after hours of installing and removing etc. I realized that one of the slots didn't work. No matter what ram I put in the computer would refuse to run.* Anything could be wrong with the computer, so you have to isolate what exactly is the cause, ie one ram card, one ram slot, one ram card in a specific slot.

Hope you can understand my rambling. Good luck!
