Everyone, I made a mistake in this listing. It is actually 533MHz not 400MHz. I can't change it because there is 1 bid .Freeme1983, if you win this I will gladly refund your credits if you like. My mistake, sorry
Forgiven, I am currently running PC2 4200 modules, one of which is the exact same module as this Samsung. only a slightly different end numbering. Your 512MB module's label reads PC2-4200U-444-12-D1, mine says PC2-4200U-444-12-D3 so it could be like reuniting brothers or something.
