exceeding maximum speed in Ram

this may be a foolish question but i want to know what will happen if i will try to install a ram with faster speed than the limit of my notebook.

for example i have an older centrino which can only take up to pc 2700 ddr sdram and put pc 3200. what do you think will happen if i put pc 3200 ram? will it downclock? or will just destroy my centrino chipset?

foolish question but some people are not aware that older centrino with 855 integrated graphics can only take up to pc 2700 ram (ddr 333).

 

Well, either it will downclock or it won't work at all. If the memory doesn't want to downclock, your system will just not start. You'll stare at a black screen w/o it posting.

I actually installed 3200 on a 2700 desktop and it worked fine. People have told me that some sticks won't downclock like that.

In any case, it won't give any speed increase.

 

don't worry. nothing bad will happen. the speed of the ram is dictated by the speed of the system bus (in your case 333MHz), so the pc3200 will be down-clocked to pc2700 (I'm speaking from experience).

be carefull not to do the oposite: inserting a lower speed ddr-ram (like a pc2100 in system that runs with pc2700) - I'm not sure what could happen, just DON'T DO IT!

hope this helps!

 

my bus speed 533 Mhz, and i use RAM DDR 2 x 512 MB pc2700, i feel my notebook work fine, but i plan to upgrade to DDR2.
can it works ? just information my notebook use 915 chipset, pentium m sonoma 760 2 GHz.

 

I don't think it should be DDR RAM that's in there now. DDR and DDR2 RAM actually have a different number of pins, making one impossible to swap with the other.

In any case, the two are not interchangeable. Either you have mistaken your bus speed or the memory you have in there now....that or I've mistaken

 

i admit i posted a question that i think i know the answer.. Well i have a notebook with old centrino chipset. the chpset has intel extreme graphics 2 (its an integrated graphics)..

i wanted to upgrade my ram so i bought kingston 512 ddr 400 pc 3200. i thought that it will downclock and that my integrated graphics can support that kind of ram.. but unfortunately it can't... so here's what happened..

i installed the ram.. then i tried to boot and it did boot unfortunately after 10mins+ the most feared BSOD came up! i tried again with same problem coming up!

well i tried to isolate the cause and i found out later that my integrated graphics will only support ram up to ddr333 pc 2700... now you will ask the effect of putting higher speed ram.. well i tell you my graphics now is misbehaving! it doesn't have that kind of problem not until i tried to install several times that ddr400 pc 3200.

now if you are upgrading ram in an older centrino with integrated graphics do not just look at your processor, also
look at your graphics card and check the limit of ram speed it can support...

here's the intel site where i found out the types of ram my graphics card (by the way i have the 855 GME chipset) can support:

correct me if m wrong...
