286203 2004-10-30 03:03:00 Hey guys,

I know RAM usually clocks back to the FSB speed of the mobo if you put higher clock speed RAM in, does this apply for a gap as big as 400MHz RAM in a 266MHz FSB mobo? I'm just trying to problem solve why a new pc I built won't start up.

Cheers!

Or there might be a jumper on the motherboard that fixes it. So, it works

Put some 266 in & away it went
Combined some 266 & 400 & no go either

286206 2004-10-30 07:40:00 What you could try is,

Put in a 266 chip so you can get into the BIOS, manually set the DDR clock to 133MHZ, and then shut down and put the 400 back in.

It will run the 400 at 266 and it will work fine (hopefully)

Pull ram out check for dust

Try a different slot
