Can I mix 266 and 400 DDR Memory?
I have two 512 meg DDR Memory Modules. They are both 512 meg as
mentioned and PC3200. The thing is the new one I just bought was a 400 (What does this number mean, is it speed)? and the other seems to be a 266 going by the label on the module. I want to put these both in a new system I'm building but I'm concerned if they will work properly. Will it slow my system down or cause any reliability problems? If so maybe I'm better off with just the 512meg 400 or either upgrading the other to a 400. |

I wanted to add this, if it is true that the 400 is faster but they both work together would it help if I maybe put the 400 in the first memory slot so that the system uses that first and not the 2nd module as much? |

PC2100 = DDR266 PC2700 = DDR333 PC3200 = DDR400 PC3500 = DDR433 PC3700 = DDR466 PC4000 = DDR500 PC4200 = DDR533 |

You can only set the BIOS to run your RAM at the speed of the slowest module
in your system. Hence 266MHz. I'd ditch it, IF your system will run stabley at 400MHz with the other one. -- DaveW "MarkW" wrote in message ... I have two 512 meg DDR Memory Modules.

Mixing the two would only increase your address space not the speed of
the ram as the entire ram bus has to be run at the same speed, so it has to take the slower speed as not to cook the slower chip |
