evo d300 a nd ram upgrade

Hello,

Do you know what type of RAM is installed on your older laptop? You need to make sure that when you are upgrading RAM, you need to much the type of RAM (DDR2, DDR3, etc) and the speed. You should be able to look on the RAM and find some sort of information, you can post it here and we can help.

Cheers,

There are a few different evo d300v models, some of them should work with 512MB sticks (P4, P4 celerons) and some wont work with 512MB sticks (P3, P3 celerons).

It is not a laptop it is a desktop model. the information that is on the sticks is pc133r 333-542-82 m3990s2858cT1

All the compaq evo d300v models I know of are dekstops.

The info on the memory sitck is pretty useless now, to figure out if you can run 512MB sticks we need a more exact model number (you can normally find that on the compaq barcode sticker)

The serial number is 7P27KHLB904v and the other information that is on there is DV/P17/20/K/128r. on the front of the case i says evod300v.

It says pentium 4 on the front of the case

Ye gawds, I hate the compaq site.....I keep getting different results from the serial number. :S

Anyway, I can tell from the DV/P17/20K/128r that is a P4 1.7GHz, 20GB HDD, 128MB RAM. It should work with 512MB sticks, it is likely that your samsung sticks simply wont work in the compaq, I've had similar problems with compaqs in the past. Compaq have always been pretty RAM sensitive in general, I've had various compaq boards that will only work with 1 out of 4 RAM sticks (non-compaq branded sticks).

The only things I could suggest is try removing the 128MB stick and then installing the 512MB samsung stick, and posibly clearing the CMOS.

Could anyone recommend the sticks that are most likely to work other than compaq.

I'd try crucial-

I'd use the 'shop by manufacturer' method, if the RAM fails in your system at least crucial should give you your money back, or different sticks to try.
