i have just bought and installed 1gb ddr2 into my sons pc. he had 1 gb pc 5300 i put in 1 gb pc 667 i know thats a faster speed but it should underclock to match the slower, but his pc keeps crashing ...complete power off i checked the ram and found 1 running at 266mhz and the other at 333mhz it said 1 was 5300 and the other was 4300.. i have since removed the new stick he now seems to be a little more stable do you think the ram is faulty? or is there a manual setting i should have used
win xp , amd athlon 4000+ msi m/b

You have other atributes to consider...

CAS latency, voltage, EEC Non-EEC, buffered Un-buffered, Machine specific Non-machine specific

All these have to be met for Memory to work together...

i always thought if not a pair the faster one would underclock to match

Normally that is true but they still have to be the same as listed above....

would have been simpler to buy Modules of the same speed so ya don't havwe to go mucking about with other settings to satisfy both modules...

Do you have trouble sourcing PC5300
