Mix match memory dimms

Are there any problems in adding/installing additional SDRAM pc133 dimm on motherboards that have 66 or 100 bus speed with original dimm already installed.

  1. Nope, PC133 is backwards compatible.

  2. Theoretically, there is no difference. But some boards will be the odd ones out. Note that this is very rare.

  3. hmmm I asked that same question a while back, and I was told that Yes the can be used together, but they will run @ the Slower RAM Speed....
  4. Yes you can mix them, and yes they will run at the slower speed. Sometimes, on older boards they may not work. Is that inconsistent?

  5. Just continue running yoru bus speed at 66 or 100 (whatever it supports). The memory will run at the slower speed, but it will work.
