I've read you need atleast 8 passes to be sure and I believe from observation but could be wrong that each pass tests different things as do the tests. I've only ever waited for 8 passes, once or twice however (just after I'd read about it), it took ages. > I pulled and reseated all the memory and then did 5 'make -j8 build' runs > successfully, no more hangs. > > Very strange, but this is why I like to stress-test new builds...

Memory testers, if at all, only find specific issues (mostly by writing and reading bit patterns to RAM). They can't stimulate and stress the hardware as a build process (e.g. of an operating system) does. Memtest and such only have limited use. Yours, Norman

I actually resolved this by pulling and reseating all the DIMMs. Oddly enough, prior to that, the box went through 3 complete runs of memtest86+ without error, but continued to hang at random spots during 'make -j8 build'. I pulled and reseated all the memory and then did 5 'make -j8 build' runs successfully, no more hangs. Very strange, but this is why I like to stress-test new builds... -- Joe Gidi j...@entropicblur.com "You cannot buy skill." -- Ross Seyfried
