Hello fellow lampers, this post has nothing to do with lamps or sheep. I have an older small desktop computer which I'm in the process of upgrading, but it uses DDR2 laptop ram., it can handle a maximum of 8 gigs, but it only has two ram slots, so each card needs to be 4 gigs. Can anyone help me out? Cheers from Jeff.
Do you mean you want to upgrade them to 8Gb? Check if they are the short (usually the memory chips are in a box shape) or the long ones (single file) then buy the correct type. If they are the laptop ones just buy the ddr2 sodimm 2x4Gbs set. There also is a ram limitation on the OS depending on versions like windows XP x86 has a 4Gb limit but the x64 has a 128Gb limit.
If you mean you want some ram chips, I do have some but they are a generation ahead being ddr3s and 4s so they won't fit and sending that across the pond will be pretty funny in postage. Sorry to not be of any help.
Thanks for the offer, but I meant exactly what I wrote, I'm looking for two 4gig DDR2 laptop ram cards and the link below shows the model of small computer which they are for and if I could have found any for sale at a reasonable price, then I would have bought them and I shall install Linux Mint as the operating system.

Jeff, EDO ram (laptop) non ECC but you need to know the speed i.e. DDR667/ DDR800 The main problem is that DDR2 4GB modules were pretty rare at that time and like rocking horse poo. 2GB modules are easier to get but as you say, 4GB (total) is barely enough for Windows 10. Linux based OS (mint is good) will definitely help as the overheads are much less than with W10. It might be time for a replacement laptop. Martin
Hello Martin, thanks for the information, but I already knew it and it's not a laptop which I'm hoping to upgrade, it's an HP Compaq DC 7900, which is a very small desktop computer and the link below shows that model. I currently have it working with a couple of two gig., ram cards and a 320 gig., 2.5/7200rpm., hard drive on which I installed LM., 20, yes, that type of pc., uses laptop ram and a laptop hard drive and an external power supply. Because of it's dimensions, it can be fitted to a monitor stand with a bracket and then it's like an all in one computer and it takes up less space. It currently has a dual core 2.60 GHZ., processor, but some of this type of pc., can handle a quad core processor, however, that may be the more modern versions which are model DC 8000 and upwards, I shall have to check. I do have a quad core processor amongst my spares and I have a one terabyte 2.5 laptop drive, so hopefully that makes my plan for that pc., clear. paparazi hp dc7900 ultra slim specs - Google Search
No, Jeff - the individual words are English ones but as a group, they convey no meaning to me at all...
@David Shouksmith He needs more memory for his computer. The correct physical format, correct size and speed. The rest is nomenclature. This will make it work better and maybe faster. (ex IT manager)
@JEFF JOHNSON I have just seen the price of genuine "new" ones - it would be cheaper to replace the machine. I did find these 8GB 2x 4GB 2GB 1GB DDR2 PC2-5300S 667MHz Laptop SODIMM RAM For Samsung LOT UK | eBay - seem to be right shape but 667MHz not 800 a 'snip' at £120 or a 2nd user machine with 8gb already onboard for £80 HP Compaq DC7900 Desktop SFF PC Core 2 Duo 3.0GHz 8GB RAM 120GB 1TB HDD WIFI | eBay
Thanks for the information and I have checked out the price of new 4 gig ddr2 ram cards before and they are very expensive. Some may turn up sometime and I'm not in a rush, as upgrading that pc., is just a project. The pc which is shown in your link is a larger one, the pc which I have is a dc 7900 elite small form factor, HP also used the model number DC7900 for a tower pc. Fireexit1
Hi Jeff, You may find that under Linux Mint, Lubuntu or even Debian, 4GB may prove to be sufficient for everyday tasks. You can check memory and swap file usage by using the "top" and "free" commands from the command prompt. In my experience, upgrading to a solid state hard disk (SSD) will improve the speed of the PC tremendously, much more so than extra RAM beyond 4GB will.
I agree with Phaedrus42 in that a solid state drive will have the most dramatic effect on everyday performance. Most 2.5 inch drives are just 5400 rpm, so fitting an SSD will make it feel like night and day. Many of the manufactures offer Acronis True Image as a free download, so imaging the old drive to the SSD is really straight forwards and keeps your original install verbatum (although not important if you're going linux mint OS)
Yes, I realised that much - I was just being, er, playful... The daft thing is, I've saved various memory cards from old computers but I've absolutely no way of knowing they're what Jeff is after. I went looking for them this afternoon without success - but I did find that missing Tilley R55 pump I've been after for ages! Now I must remember to put it back in the R55...
Hello David, thanks for looking and I would be pleased to obtain any memory cards and other computer spares because I repair and upgrade computers for another hobby.
No problem, Jeff - I'll drop them in next time I'm in Shetland! Unfortunately, however, the ship I normally use to get there (Marco Polo) was last seen on a beach in India. I'm desolate...
Not sure what the rules are now on swapspace but it used to be 20% of available disk in my heady days of HP-Unix and Oracle. Used to make people cry as disk was not cheap then. Chris
I have now checked out which processers the pc., can handle and it will not be able to handle the quad core processor which I have in stock, so I shall stick to the dual core which is currently in it.
