The module in my 10v which was ordered directly from Dell back in September has the name 'nanya' on the label; model No. NT1GT64UH8D0FN-AD 0932.TW.
Under the Bar code it has 1GB.2Rx16.PC2-6400S-666-13-A2.800 and below that ML098030EG.X2 followed by an even longer bar code!
There is of course no guarantee that they are still using the same modules, in fact I would go as far as to say that they probably aren't!
I hope this helps anyway, although I am just a bit curious to know what you were hoping to gain from these details?
Edit: Having just read your earlier post (in German!) I wouldn't worry about trying to match this if you are considering replacing it with a 2 GB module. Any 'standard' 5300 generic module will work fine, and some manufacturers such as Crucial (and Kingston also I believe) will sell ones which they guarantee are compatible with your particular model.
