Bought 2 of these 1GB modules a few days ago. As soon as I installed started to get random errors. After some research I downloaded a memory tester. It reported memory faults on both units, So I've returned.
I've bought weel over a dozen memory upgrades over the last 15 years and only ever had one go wrong. To have two faulty in one order is unheard of. Difference this time? I've always bought branded memory before and will do so again from now on.
Those of you that have not had issues, I would seriously advise you download a memory tester (lots on the net), as often errors don't appear for many days or weeks.
This is obviously cheap/untested memory and I would would advise anyone 100% to invest a few more pounds for branded and avoid this at all costs.
