Need a little guidance...Can I replace PC2-4300 with PC2-8500? Tags: Memory Computer Motherboards Last response: May 31, 2010 3:51 PM in Memory Share Wangstang May 31, 2010 3:43:40 PM The computer is a Compaq Persario SR2150NX running Vista. Basic specs Processor: Celeron 356 (C) 3.33 GHz 533 MHz front side bus Socket 775 Chipset: ATI Radeon Xpress 1100 for Intel Processors Motherboard: Manufacturer: ECS Motherboard Name: RC415ST-HM HP/Compaq motherboard name: Alhena5-GL6 Detailed Specs can be seen here: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00... Crucial's site says not to exceed PC2-5400: http://www.crucial.com/store/listparts.aspx?model=Presa... But, I was curious to know if PC2-8500 will work in this computer and if it will work, what speed will it run at? I also don't mind reflashing the BIOS if it will give the computer the ability to run PC2-8500 at it's fully rated speed.
