I bought 2 sticks of RAM and it displays that it is 533Mhz. I really cant be bothered chasing them up and returning it, so can someone tell me how much performance I am losing by 533Mhz, rather than 667Mhz RAM?
So do you have any idea how to fix this? 2 of my sticks are reporting DDR2-533 while the other 2 are running DDR2-667 - making the entire system run at DDR2-533. I have tried updating the BIOS. Still wont work
Oh, BTW I am running vista. Can this have anything to do with the SPD thing?
Unless those 2 533 sticks are actually 667 (which they probably are not), there's nothing you can do. You could return them and get a pair of 667 sticks but that's all.
An SPD chip is an EEPROM that stores timing parameters and whatnot for the stick of RAM so you don't have to set things manually. It's got nothing to do with your OS.
