MEMTEST
what a little beauty.....
I found 2 tiny little addresses faulty, on my TWIN MOS stick of mem when run at PC2700 , even at 7-3-3 2.5
The stick of Infineon in the other slot passed even at PC2700 6-2-2-2 so I nicked the matching pair for it from Sair's (the other halfs) P4 which only runs it at PC2100 speeds, dropped both sticks of Infineon in, tightened up that timing and ran MEMTEST and its all clear. Her P4 is fine on the Twinmos at 2100 speeds.
I BELIEVE (*prays*) that is the reason for my random lock ups......
a little address at 194mb position and one at 74 on one stick of otherwise perfect ram. Only test 3 and 4 showed it up...the others were perfect.
CHEERS GUYS FOR YOUR HELP........
and if you think thatsNOT likely to me the random freeze answer, do tell me
