I am upgrading a Demension 4300 w/ a 1.4gig P4 actual speed is 1395.
Crucial says it uses PC133 which it now has. BIOS says the bus speed is 100mz.
IF i put in PC100 will it work at 100 or 133 or not at all?
if you put ram of mixed speeds in the same machine, say 100 and 133. it will all run at the speed of the slowest module (100Mhz) in this case. unless the compatibility of the motherboard has other caveats. check the manufacturers ram support list for that.
I wouldn't mix them. Just going by the bus speed would 100 work at 100?
Beside, would you believe anything that Dell said.
I got this computer at a thrift store-$5.35 That's about the going price for a Dell.
Mainly because of their support - or lack thereof.
