can anyone recomend a good utility fro tesing a computer before it
goes into service??....i have been using passmark but it tends to
crash on some machines even though no errors are showing...
.i t needs to put a good amount of stress on all components especially
ram and hard disk
thanks..
Ummm, did it not then suggest to you that the machine is even more
instable than if it'd generated an error?
Each component is best tested separately. For CPU, Prime95 Torture test,
"In-Place Large FFT" mode (with mem size increased 150% if/when CPU has >+
1MB cache), for several hours.
Memory, Memtest86
Graphics, 3DMark2001
Total thermal margin, 3DMark2001 and CPUBurn (set to normal priority)
concurrently.
There is no "all in one" test that will even come close to testing
stability reliably, including passmark. Each subsystem must be isolated
else no subsystem ever gets sustained peak utilization.
For hard drives, it's not so clear cut. Hard drives don't generally crash
but rather suffer longer term from heat stress.. In such a scenario
touch-testing the hard drive casing is easy enough if you don't have a way
to take an accurate temp reading. Run the manufacturer's diagnostics, one
of several disk scanners' read/write/verify the whole drive, and a general
throughput test to verify it's operating within expected parameters per
device and interface used.
