I've just get "new" comp Sony Vaio PCV RX550 1.5 P4(nVidia GeForce 6600 256KB) - this one is my second but I want to change memory core from 2x256 to 2x512MB so I deicided to buy two cores PC2100 DDR DIMM. Hhhmmm my problem is that on the case stands something like:...256MB expandable to 512MB - is that mean I cannot have 1GB in this one, if it'll help - chipset Intel 82845 P4. ******* hell please anyone help me solve this problem...
