I bought the lowest I could buy from dell 256 one dimm. I have checked crucial and kingston as to which ram they recommend. They both say PC2100 however when i open my 600m I found the 256 stick to be Promota(something like that) PC2700 ram. I am thinking 2 things A. Crucial and Kingston are right it uses PC2100, however maybe since the new dothans have come out which I have a dothan that dell switched chipsets to a PC2700 one. Which ram should I get? PC2700 is actually cheaper that PC2100. Thanks guys.

Any reasonable diagnostic or benchmarking program will tell you whether your RAM is running at PC2100 or PC2700 speed; look for Aida64, SiSoft Sandra, Fresh Diagnose, etc.

If the PC2700 is cheaper then get that, if needed it will run at the slower speed anyway

interesting point there cemisis. I know DDR will scale down and although I have heard of some ram being incompatible I have not seen it. I think I am going to go for the kingston 512 stick of PC2700 ram.

alright i downloaded sisandra and it shows my memory running at 266mhz speed even though the memory chips have a label of PC2700. I am figuring dell used PC2700 because it was cheaper. I know DDR is backwards compatible should I buy the cheaper pc2700 ram or will PC2100 ram have lower CAS ratings?

I was pretty sure that the 600m supports the faster RAM. Stick 2700 in there and see what happens.

As you know by now, Crucial offers CL=2.5 for 600m; check Kingston's specs.

BTW, doesn't your BIOS show the RAM speed? (Hit F2 on bootup to get there.)

KCK, Kingston PC2700 and PC2100 are speced to have the same CL timings. A 512 stick of PC2700 stick on newegg is 98 bucks PC2100 is 117 shipped. So PC2700 is cheaper. I know that DDR is backwards compatiable however like I said I know there has been some instances where some desktop ram like PC4000 was not supported on a motherboard of PC3200. It is weird that Sisandra reads the ram at 266 mhz considering that my desktop I built has a ASUS AV7333 motherboard with PC2700 ram running at 333mhz while my processor runs at a 266 (133x2) fsb. Thing is on the label of the ram in my 600m it says that it is clearly pc2700? Should I get the PC2700 then?

get the pc2700 just for the fact that it is cheaper. 600m only runs at 266mhz.
