Slavedriver Posted April 13, 2007 Share Posted April 13, 2007 I had two ValueSelect 512Mb 667Mhz (VS512MB667D2) modules and recently bought 1Gb kit (2x512Mb) ValueSelect to add myself another Gb of RAM. The problem starts when I insert all 4 planks of memory. Windows refuses to boot (says some system file is missing and the file is not always the same) and when I try to reinstall it I get BSODs at different stages of install one way or another connected to the memory. When there are only 2 planks inserted (new or old) memory works on 553Mhz frequency. When all 4 are inserted it is suddenly 667Mhz (like originally was intended). I haven't done any overclocking, voltage adjustments and so on. Memory seems OK (Memtest hasn't shown any problems). Again it happens only if all memory slots are filled. It works fine with 1, 2 or 3 planks placed in random slots. EDIT: Forgot to say. BIOS is the latest available. EDIT: Tried upping voltage to 1.9V. Didn't help. Also I occasionally can't even POST and have had to reset CMOS a few times already to even get into BIOS. Link to comment Share on other sites More sharing options...
