Thread: What Ram for this please

My Sisters HP only has 512GB ram, I would like to install another 512 for her.
But it's an old one. Would I use 184 pin DRAM? I believe the bus speed is only 133Mhtz
but ram speed is usually backwards compatible. isn't it.
No we don't want to upgrde to another pc, just want more ram for her existing one
Thanks Mario
