Back when I gave the Snow Leopard development build a test run, I noticed something weird that I chocked up to running beta software.
My G5’s RAM was wrong, listing as 6GB when it is actually 10GB.
I didn’t think much of it and went on working on other projects.
Booting back into Leopard, I wasn’t happy to see the RAM size remained incorrect. On top of it, I ordered a cheap 2x2GB set of sticks to further boost my G5. It was time to figure out what was going on, keeping in mind that I had not messed with my RAM at all. The only thing I had done was replace the thermal paste on the CPU.
Here’s my troubleshooting process:
1 – Open up the G5 and reseat the RAM. No fix on the first go.
2 – Reset the NVRAM. No fix either.
3 – Use a tiny bit of thermal surface cleaning solution that I use on CPUs when I put fresh thermal paste on to gently clean the edges of the sticks. Again, no fix.
4 – Spray a little canned air at the empty RAM slots. Again, no fix.
4 – In frustration, I reseated the RAM with a little more firmness. All is well. For now.
My Power Mac is showing 12GB of RAM now (which is what I have in it). Another 4GB is on the way, so I will max this ancient machine out shortly. The answer is… there is no answer. Maybe this G5 is old and near death. We’ll see.
