-- Posted by yoshiness at 1:06 pm on June 18, 2009 Yesterday when I opened up the computer, we checked the RAM sticks, and found out why the number was so odd. Our computer originally came with 128 MB of RAM for Windows Me. Then my dad installed another 256 MB. That totals up to about 384 MB of RAM. Are RAM sticks cheap, especially the 256 MB ones? Or what about 1 GB or even 512 MB? Why are they computer model specific? -- Posted by oink at 1:08 pm on June 18, 2009 RAM is quite cheap but it also depends if they are DDR, DDR2 or DDR3 -- Posted by lyfsux420 at 1:15 pm on June 18, 2009 Ram is pretty cheap right now, at least it was last time I checked.  But there is different types.  It could be SD-RAM or DDR, DDR2 or DDR3.  You just have to make sure you buy the right type. -- Posted by allsmiles at 4:04 pm on June 18, 2009 The old types that are not produced any more (DDR, probably SD also - in fact, definitely, I remember struggling to find cheap SD back in 2000) are relatively expensive. DDR2 and DDR3 are quite cheap - if you look about, it's probably $15/GB tops. RAM is rarely model specific. It's only the big manufacturers that add in extra bits so that you have to buy their RAM - so that they can bump up the prices. -- Posted by espresso8097 at 8:55 pm on June 18, 2009 DDR and DDR2 are pretty cheap these days.  Even DDR3 isn't that bad. Just by the low number I am guessing you have PC-3200 or less DDR SDRAM.  But only way to know is to check.   -- Posted by mtguy8787 at 9:46 pm on June 26, 2009 got to crucial.com, and use the memory checker utility to see what type of memory you have + the maximum amount of memory your computer will support. Yes, most RAM is very cheap
