I bought a my son a PC a few months ago. It came with only 256MB of ram. So I yanked that and added two sticks of 512MB to get 1G out of it. Yesterday I pulled one 512 stick and added a 1G. Problem is the computer is still only recognizing 1G. Here are ths stats. It states below it can take 2G. CPU: Intel® Celeron® D Processor 335 (256KB L2 cache, 2.80GHz, 533MHz FSB) Operating System: Microsoft® Windows® XP Home Edition (SP2) Chipset: Intel 865GV chipset Memory: 256MB DDR 333 Expandable to 2GB Hard Drive: 80GB Optical Drive: CD-RW/DVD combo optical (48 × 32 x 16 × 48) Video: Intel® Extreme Graphics2 3D 64MB shared video memory Sound: AC '97 audio Network: Intel® PRO 10/100Mbps integrated Ethernet Modem: 56K ITU v.92-ready Fax/Modem Peripherals: Standard keyboard, 2-button wheel mouse, amplified stereo speakers Ports/Other: 6 USB 2.0 ports (2 in front, 4 in back), 1 VGA external connector, 1 serial, 1 parallel, 2 PS/2, 5 audio (2 in front, 3 in back) Dimensions: 7.25"W x 14.125"H x 16"D
The computer may not be able to support a 1g chip. How many slots are there? If there is 4 slots, to get to that 2g capacity you may need 512 * 4. Try moving the 1g into the first slot, and booting up with just that. BTW: Is there a reason you need 1g 1/2 of memory? The processor and video card are like 2's and the memory is enough for just about anything. 1g should be plenty for anything you try to do with that processor/video card. The Celeron is what's really slowing you down.
with most DDR motherboards you need to keep all the ram sticks the same size. i would check in the manual.
Vibrant, did you get a cheap 1 GB stick? ($70 or less) There's a configuration of 1 GB sticks (x4 high density RAM) that are cheap to manufacture but not a lot of motherboards support them, so they only work on certain systems. Here's a post on it. Here's another post on it. Apparently one of the symptoms of a non-working motherboard is that it only recognizes half the capacity of the memory stick, which sounds like your situation. So adding a 1 GB non-working stick to a system with 512 MB will only = 1 GB of RAM. ETA: Here's a good summary of what's going on with the different RAM chip sizes.
Jason, you are correct. Just pulled the other slots 512 and left just the 1G card in it. The PC only recognized half the stick. I won it off Ebay. Guess I'll have to re-Ebay it.
