What if some of my RAM is good and some is bad?
If you receive an error message that says "RAM bad," how do you figure out which chips are good and which are not? If you don't have a chip tester (and most of us do not), then try this method to test each chip:
- Shut down your PC, remove the plug, and open the case.
- Take a look at your RAM sockets. If you have any empty ones, try swapping your RAM modules into them.
- If you don't have any empty sockets, swap the RAM module in the first bank with the RAM module in the second bank.
- Plug in the power and restart your PC.
- If the error message returns, shut down your PC and remove the plug again.
Try eliminating the modules one-by-one to isolate the bad chip. Note: This may not work if your system requires you to have RAM modules installed in pairs. If so, then remove the chips in pairs.
