What would arise if I put 533MHz DDR2 4200 laptop memory inside a laptop that call for 266MHz DDR 2100?

Would the laptop freshly run at the slower 266MHz speed, or not run at all? I hold the extra memory kicking around and would like to use it first.


Answer:

I would be more concerned about DDR vs. DDR2 than 266 MHz vs. 533 MHz.



Suggestion: call round an online RAM seller such as crucial.com and hold it scan your system. Among other things, the scanner will give a roll of what sticks the site has for mart which are compatible with your computer. If it say that DDR2 533 MHz sticks will work with your system, move about ahead and use the ones you have. If it doesn't voice that DDR2 is compatible, then you'll enjoy to find another use for those sticks.
It would not run at all.



DDR is incompatible next to DDR2. Even though they are both 200-pin modules, they are not interchangeable.
it wouldn't work because the MHz is different and your board probably would not recognize it
If I evoke correctly, DDR2 using a different pin layout than DDR. I don't think you would even know how to physically insert it into the slots.
It wont boot and you could damage the electronics if powered up within this fashion. Be discreet and do your research at Memory.com



Good luck!
It wont work. They are not interchangeable with respectively other.
DDR2 will not work well near DDR. Doing this will most likely effect an error, make your computer not boot up, or freeze. Get regular DDR memory for you laptop, even if the DDR2 happen to work chances are DDR would work much better anyways.
