Yes I do have a 64bit OS, who would use 32bit OS with 4GB Ram.
Anyway, I usually do some multitasking which consists of some data transfers(slow due to slow devices like gps) and browsing with a lot of tabs while running some programs like MS Visual Studio and MS SQL Developer or Adobe Photoshop/Illustrator. I also do play some games.
I should have included that I have an SSD drive (Samsung 840) - I dont know how to calculate its speed to compare it with the RAM speed to check if the ram is a bottle neck or vice versa.
Another thing is that I have owned the 667MHz ram for about 3 years so I just cant return them and recently I have found a pair of unused 1066Mhz and bought them as DDR2 is becoming a little rare and the ones left are expensive.
The 667Mhz worked perfectly alone, even the 1066mhz (running @ 800Mhz) are working fine alone - i still havent tried them all 4 altogether.
I just thought that I should upgrade the RAM as I recently upgraded to SSD , because when I researched a bit I found out that the lowest speed for DDR2 is 667 while the highest is 1066 (right ?) so I thought Ill buy a faster RAM which ended up as not compatible at 1066, my mistake.
I should have listed all the specs before, so here it is :
Motherboard - Gigabyte GA-MA78G-DS3H
CPU - AMD Athlon 64 X2 6000+ 3 GHz Dual-Core
RAM - Corsair 4GB 667MHz OR Corsair XMS2 1066MHz
GPU - Nvidia Geforce Gainward 8800gt 1024MB Golden Sample
SSD - Samsung 840 120GB
HDD - Seagate Barracuda 7200rpm 1TB
OS - Win7 Ultimate 64Bit
