Hello i have a dell latitude c610 model# PPO1L (labtop) i ordered new ram for it and it did not work.

I have two ram sticks of 128mb. one in each slot=256mb total. ok now here comes the problem. i removed one ram stick installed new 512mb and computer would not start. moved the 512mb to the other slot, still with a 128mb in the other slot,when i tried it that way i only had 128mb of ram. so the 512 is not recognized or not working, i also tried the 512mb by itself and it would not start or boot,nothing.

this is the ram that i was trying to install,brand new. i have heard it could be a density issues,
but i dont understand that.IS THIS THE WRONG RAM?
CDN133X64SC3-512M -- CenDyne 512MB 64x64 SDRAM PC-133 144-Pin Laptop SODIMM 8 Ch...

NOTE:my computer was unplugged, with no battery,when i installed the ram, i was touching the case and i touched metal before i touched the ram sticks at all.could i have shorted out the new ram or was it just bad? my two 128mb's still work fine so i am not sure. i am just frustrated? thanks very much. ALSO IF IT IS THE WRONG RAM COULD YOU PLEASE TELL ME WHAT I NEED, THANKS AGAIN.

Your cendyne seems awfully cheap?

The crucial memory is a lot more

Does the bios have an option to set the memory for cas 3?

If so try changing that and reseating the 512 meg stick.

i have a level 2 cache if that is what u are referring to? i am not sure what cas 3 is.

is it the price of the ram or the name/manufactor when u mentioned it was cheap? i do not know how to change the anything in the bios.

Cas level is the speed of the ram, 133 cas 2 is faster than cas 3

If you go into bios setup, F2? is there a setting for cas level?

If you look at the 512 meg and the 256 meg stick, one is CL2 and the other is CL3

If your bios was set to CL2 then your CL3 512 stick wouldn't work?

The other possibility is that stick is dead DOA

I am just using a educated guess, memory is one of my areas of expertiese.

CL is cas level

see this for the difference between cache and cas

Frequency: 133.3 MHz
CAS# Latency: 3.0


The other possibility is that 512 meg stick is dead DOA
