How to buy old DRAM?
I went to the A-Data website expecting to be able to be able to look up historical data on devices no longer sold, but they don't seem to have it. The memory sticks I currently have in my old desktop read "DDR2 800(5)" and are 1GB per stick. There are also several other numbers on them including "M20AD6GI4170I1E58" and it doesn't help that they seem to use o O I and 1 but all I know is that the memory was supposed to be 5-5-5-18. How can I look on Ebay and find something that is close enough to work? I would like to add two more sticks so that I have 4GB.
Thanks. |

If you can't find them, or if the price is extreme, it's time to
upgrade. That's what I did last time, when the cost of older slower memory was 200 to 300% more than current memory. Good luck. |

Well, that is the thing, you can't find old parts new but you can find old parts. The problem is decoding whether an non-exact match is close enough to work. |

The problem is decoding whether an non-exact match is close enough to work. Copy the part number from your existing "Old" RAM and do an eBay search with it. Chances are good that somebody has listed it. Or something close. Worked for me for my elderly MBs... Chris |

How can I look on Ebay and find something that is close enough to work? I would like to add two more sticks so that I have 4GB. Thanks. They seem to keep a pretty horrid web site. You can use archive.org to go back in time, assuming the web site actually has some information of value. https://web.archive.org/web/20090217... peUse=DeskTop A typical part number might look like this. AD2U800B2G5 The "2" would mean DDR2. The "U" means UDIMM or Unbuffered DIMM. The 800 is the speed. The B2G5 would specify some specific characteristics, like maybe 2 ranks, CAS5 ? (The word "Banks" is used for the innards of a DRAM chip, while the word "Ranks" is reserved for arrays of chips on the DIMM itself.) I would go back to the module, and look for another number to work with. In this Ebay example, if I look at the picture I can see an M20... part number on the sticker, but that is not the AD2... number used to buy the stuff with. http://www.ebay.com/itm/ADATA-2GB-DD...#ht_2393wt_975 When Micron/Crucial does this sort of thing, they might include two stickers. One sticker containing an internal part number (which you can eventually find a datasheet for), as well as a number you can use to shop for one. I'm not seeing this feature on the ADATA products, but maybe I missed it. I'm guessing this is one product, where you would want to "keep the box it came in". You can use CPUZ, to dump the technical data. For whatever that is worth. http://www.cpuid.com/downloads/cpu-z/1.67-en.zip http://www.cpuid.com/medias/images/e...es-cpuz-04.jpg Paul |

I would like to add two more sticks so that I have 4GB. - You'l be paying premium prices - everybody is going to want 1G modules. Be careful you don't buy the cheaper extra-chipped -parity- DDR2 generaly for server environs. Home use PC memory don't use it. You want non-parity. Believe I bought some, an extra stick last year, after cursorily running a software PC parts identification program -- which indicated I had DDR of another sort than what I actually had. No excuse, on my part, for not opening and pulling that stick, and cross checking the WEB for nomenclature on it until I knew exactly what I had. I bought it twice, IOW, once more after I got it right. Think what I bought the first time fits for another computer, though, whereupon I just stuck the extra stick somewhere in that case;- somewhere else in the case would be aside from already being fully populated. To be sure, in case memory goes bad. ...Fat chance. Easier, price wise, sometimes just to update. There's a point when what's new catches up to a certain multiple past your present situation, when so much faster, being so much cheaper, coincides with a participle for the "what I want" now. I wouldn't personally do anything involving substaintail parts for an update off Ebay, though. |

If this PC boots and has an Internet connection, log to www.crucial.com and run its diagnostic utility. This will tell you all your options for maximising RAM. -- Don Phillipson Carlsbad Springs (Ottawa, Canada) |

I bought chips marked M20AD6G31417011E58 and they seem to work fine with no change to anything so I am happy. Thanks to all who responded. |
