Putting RAM in a computer?

Its not looking like you can. Your 7915 uses 133MHz memory. It will not support 266MHz.

Your best bet is to go up to 512 MB of RAM using the PC133 memory. Its really cheap and you will see a big difference in speed.

Also, you could think about upgrading the motherboard. Then you can start using DDR ram.

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. i think u can't put ddr instead of DIMM. ur system can handle 512 MB of RAM

If u want to upgrade ur memory then listen

1. your computer can handle maximum 512 MB of RAM

2. SDRAM memory with support for SDRAM, PC133 speeds

Because SDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible SDR

your each memory slot can hold SDRAM PCI 133 with maximum of 256 of per slot

LOL ^^^

if its both DDR (not one DDR then another DDR 2) then ya should work. Just try it, start the computer (itll say more ram) and then it worked, if not, you can always go back to normal and buy the right stick of ram. Should work though

Ideally, you want all the RAM modules to be the same size, speed, and preferably all by the same manufacturer.

It will most likely work, but the RAM will only run as fast as the slowest stick. 266MHz RAM should work at 133MHz.

I'll give you a link to one of Tweak3d.net's older hardware tutorials if you're not too experienced with SDRAM installation:

my gadget got here with 256 interior the computer,i put in 512 interior the slot you may get to,it now had 756,runs like a champ,you like a minimum of 512 for dsl,so i might positioned a 512 in it

This says the max is SDRAM not DDR. DDR won't fit in the memory slots.

Good Luck

I think a ram is too big to fit inside your computer. J.K J.K My best guess is to check your owners manual or call an HP service agent or Visit their web site. Maybe even go into best buy and ask the computer guru. Hope it helps.

open the desktop up and see if theres is a slot available and check if it fits. then all you have to do is put it in and do a good restart.

Log into www.crucial.com and scan the system to determine type and how much you can add

Dear, they are two different types so no you can not do it;

Hope this helps !
