I'm testing some DDR ram (one pc2100 and one pc2700) in a dell 4500s (1.8GHz Intel) and memtest hangs on the second test - Address Test, Own Address, No Cache.
I've tested the sticks together and separately, and the same thing happens. The test just stops after a minute or two, with no error messages and loss of keyboard control. Tested one stick in a different computer, and it tests fine. It's a brand new memory chip.
The Dell seems to run slower than I'd expect for a 1.8GHz with 384MB RAM. I especially noticed it when I was installing software from source packages - it went a lot slower than on my 1.2GHz Athlon with 500MB of pc133. Other than that, it seems to run ok.
Here are my questions: Is it obviously the cpu? Is there any linux software that will test the cpu similar to what memtest does with memory? Any suggestions for diagnosing this problem?
Check CPU temp and cooling if you can. I've seen CPUs halt unannounced (a hang like you say) when they reach a certain threshold temp. Also, it may throttle itself back if it's overheating causing the slowness. BR
