My computer Specs: Motherboard: Abit AN78GS Processor: AMD Phenom 8650 Triple Core, 2.30 GHz GPU: NVIDIA GeForce 8800 GTS RAM: 2 GB, 800 MHz (1 module of Crucial 2GB that's already in there, for 2 years now, and the new one i want to put in is Kingston 2 GB , yes it is made to work with my motherboard, i double checked it on their site. Both 240 pin) OS: Windows XP ,SP3,32 bit version My problem: I have recently bought games and video editing software that require way more memory than i have. I have the old Crucial 2GB RAM module. I bought a 2 GB Kingston module , put it in carefully as instructed. I switched on the computer , and checked it in CCleaner and it only showed 3.5 GB instead of the expected 4 GB. I put them into different slots and still 3.5 GB. When I took out the new one it went back to 2 GB. I bought a new Kingston 2 GB thinking i was given a faulty one. Same thing but this time my computer only showed 3 GB of RAM . Meanwhile in the BIOS, the 3 modules are fully recognised. I downloaded Memtest86+. Now it is running with 4 passes without any errors. I tested all 3. No errors after analysis. So why is my Windows not recognising the RAM modules? Any ideas? Thank You in advance for responses.
