Hm, that's a pity! I have used an Apacer 512 MB PC2700 module in my i-R= am for testing, but I have ordered two Kingston KVR400X64C3A/1G sticks that are on Gigabytes list of recommended ram modules[1]. The Apacer module hasn't given my any trouble though. I ran some stress tests on it last night, bonnie++[2] and stress[3] for a few hours, and as far as I could tell this didn't screw up the file system in any way. Do you have any test applications that can reproduce the error on your i-Ram? I'd be more than happy to do some testing both using my old Apacer module and the new Kingston modules when they arrive. With regards to the i-Ram being picky about RAM, check this post: http://www.nerdnos.net/?newsarchives According to this guy, the i-Ram does not support high density ram modules. Could this be what's causing your data/file system corruption?
