Slow internet with windows 7 64 bit 4 GB Ram
Problem Description: I have windows 7 home premium 64 bit.
I had 2 Gbytes of DDR2 ram and had no problem.
I tried to add extra 2 GB of ram to a total of 4 Gb.
I saw using CPU-z and on my_computer,the system was identified 4 Gb of ram as expected, with dual channel.
The problem is that my Internet works very slow !!!
I tries with IE and chrome ,and the internet speed was very poor.
I removed the extra ram , and the internet speed was high again.
I repeat it 3 times an the results was the same :
2 GB ram - fast Internet.
4 GB ram - slow Internet.
The CPU utilization was only about 5-10 %,and about 25 % of ram was in use.
I didn't try to check the performance with other programs.
I also run the windows memory diagnostic tool, and it complited successfuly with no errors.
I don't know if its relevant. I have dual boot, with XP 32 bit as the other operating system.
(with the XP there is no problem - fast internet)
