Corsair Memory works well on my IBM Thinkpad

Finally the memory arrived. It was Friday and I picked it up from the mail room, not sent to my office.
I ordered this strip of Corsair 512Mb notebook memory from newegg.com on Tuesday. The reason to select this type of memory which is not very cheap is that I concern the stability most.
USP 3 days shipping is superb. Actually they delivered it in the morning of Thursday. But the mail room’s service is too bad. Lack of labor, -- funny?
The installment is quite smooth. After I restarted the windows XP, I just can’t believe it. The speed increased at least three times. Now I can say that my old Thinkpad T30 works no worse than a most fashionable computer.
