ha ha ha ha haaaaaaaaa just thought about this thread for all the wrong reasons.
Trying to get someone a free-bee PC out of stuff in my closet, find an old 3.0ghz P4 hook it up, won't boot....try ram in another exact box but 2.6ghz, boots
out of 3 sticks of ram 2 are close 1 is way off
now remember they are ALL DDR400, but 2 have timings close togheter and 1 has timings that are off.
2 sticks worked find mix matched in the 2.6, would boot up with a full 1GB memory, swap the other way off stick in and it would only boot up with 512. get into the OS run CPU ID note all the timings.(not the bios nor the OS would even acknowledge the other stick of mem but CPU ID would show there is something stuck in there but its not working and atleast give me the stats on it)
nothing would work mix matched in the 3.0ghz machine, it was 1 stick at a time. And the crappiest stick would kick the whole system down to 2.4 took the best out of the bunch, manually set my timings, forced DDR-400 stuck the other stick in
wow it finally works.
now im going to cross my fingers and test it for stability!
DON'T MIX MATCH RAM, unless you've got the time knowledge and patience to make it work right, and if this doesn't pass the death test im about to toss at it....no go it won't leave my hands unstable.
if this wasn't a free-bee of parts in my closet i wouldn't have even gone this far. But these parts need to keep on living doing someone else some good!
