Hi,
I m having Lenovo 3000 H-Series Desktop, Intel Core 2 Duo E4400 @ 2 Ghz processor. I bought this in the year 2007 and Lenovo provided only 512MB of RAM. Later on I upgraded it to 4GB of RAM with two stick of 2GB each in 2008 but brand and frequency was different,
1. 2GB Transcend PC2-5300 (333 MHz).
2. 2GB ZION PC2-6400 (400 MHz).
I was not aware tht one can not install 2 stick with different manufacturer and different frequencies till the time it started giving Me problem. I installed this in the year 2008 and now it started giving Me problem with the error like, BIOS error or upgrade your hardware etc etc and My PC was not booting. 1st I felt it must b some dangerous which My licenesed version of anti-virus failed to detect.
But My hardware engineered came and he checked he said its not a virus but its RAM which is giving a problem and he is surprised how come My PC worked till now.....
Taking into consideration this I want to replace this. So please advise Me on following questions,
1. which is the best, durable, fastest and highest frequency DDR2 RAM.
2. I m having 2 slots of RAM so please advise whether I should install 2 sticks of 2GB each or only 1 stick of 4GB.
Thanks In Advance.
