Hey everyone! I've just installed some internal memory on my computer- well replaced a 256mb with a 512mb memory thingymajig. Anyway I'm pretty much a noob when it comes to this lol. So bear with me! Well it's definitely locked in place and a scan from crucial memory (www.crucial.com) verifies it is plugged in correctly. However I'm not sure if the computer itself acknowledges its existence. The motherboard is http://www.motherboards.org/mobot/chipsets...TI/RS400+SB400/ and the internal memory I have just installed is http://www.microdirect.co.uk/Home/Product/17219 Are these actually compatible? I apologise if this is a silly question, or I havent supplied enough information. Thank you for your time!
