further one more thing...i went thru the manual of my mobo and apparently one slot has always to be filled if i m havin more than one stick...so according to manual DIMM 0 should always be filled...
now i did this according to the manual....i installed one stick on dimm 0 as per manual and one on other slot and then again in XP i got BSOd but this tym with foll error :
Page Fault in Non Paged Area..
problem casued by Classpnp.sys
what does this indicate...a faulty ram stick..perhaps ?
but strange thing is i repeated the above config with a diff ram stick which works when alone in one of the slot...but i got beep sound with the combination
and one last thing...as per my namin convention...no matter which ram stick i put in slots c and d i always get a beep sound...and except if i install all three ram sticks then there is no beep sound but no display either
