This was odd, since at startup there was no indication of a memory problem, and it did detect all of the memory. I don't have any other machine to install a single 32-meg chip and try and duplicate the errors. Any advice or guidance would be greatly appreciated. Thanks in advance. Bill, Vermilion, Ohio Bill, The memory tests that are performed at startup are more cursory than exhaustive.
Defective memory can initially pass the startup check only to fail later.
There is a wealth of memory testing tools available, but unless you're moving a lot of memory, it doesn't make much sense to invest in memory testing hardware. I suggest a complete diagnostic package like CheckIt that performs more comprehensive tests on memory and other components. If it's convenient, you might want to return the chips to the retailer and ask them to test the memory and replace the defective chip. Anyone who sells memory expects a certain failure rate. They should have hardware to check the memory and to conclusively determine which chip is bad.
