First, rather then explain everything just read this: http://sdb.suse.de/en/sdb/html/hmeyer_memtest-sig11.html That's SuSE page with suggestions for testing your hardware to see if it's good or not (which is what I'm doing). I'm actually running that script now, and _some_ (well, 1) of the log files are _not_ the same size. I'm talking about logs in the middle of the run, not on eaither end. Am I supposed to take that to mean there's something wrong with my hardware? If so, what next? Somehow I can't belive the make should *really* produve exactly the same results each time, but I guess I just don't know. 270 is the bad log file amoung other examples: d572adc3cb360f4bac7cb88f40c378c2 log.260 d572adc3cb360f4bac7cb88f40c378c2 log.261 d572adc3cb360f4bac7cb88f40c378c2 log.262 d572adc3cb360f4bac7cb88f40c378c2 log.263 d572adc3cb360f4bac7cb88f40c378c2 log.264 d572adc3cb360f4bac7cb88f40c378c2 log.265 d572adc3cb360f4bac7cb88f40c378c2 log.266 d572adc3cb360f4bac7cb88f40c378c2 log.267 d572adc3cb360f4bac7cb88f40c378c2 log.268 d572adc3cb360f4bac7cb88f40c378c2 log.269 d572adc3cb360f4bac7cb88f40c378c2 log.27 d41d8cd98f00b204e9800998ecf8427e log.270 d572adc3cb360f4bac7cb88f40c378c2 log.28 d572adc3cb360f4bac7cb88f40c378c2 log.29 d572adc3cb360f4bac7cb88f40c378c2 log.3 d572adc3cb360f4bac7cb88f40c378c2 log.30 d572adc3cb360f4bac7cb88f40c378c2 log.31 d572adc3cb360f4bac7cb88f40c378c2 log.32 -- ---------------------------------------------------- Jonathan Wilson System Administrator Clickpatrol.com Cedar Creek Software http://www.cedarcreeksoftware.com
