Bought 2 of these and what can I say - no probs at all - Vista now works like a bat out of hell - much faster! Recognised straight away - everything now works so much smoother.
Fitted in Advent 7113 - So a word of warning if you are fittng in an Advent - make sure you know where the memory slots are located - on this model (and others) you have to remove the keyboard to fit the second module. If you are unsure about doing it - get someone to fit it for you. Although in all honesty - it is only a matter of releasing 5 small catches - 3 at the top and one on each side and the keyboard releases.
Definitley worth the money and you will see a vast improvement in performance
