1) On the motherboard the Blue ram memory slot that is closest to the copper heatsink, is ram memory Slot 1.
Also known as DIMM 1.
Ram memory ALWAYS has to be in this ram memory slot.
The Processor reads ram memory Slot 1 first.
2) The Blue ram memory slots are Slot 1 (DIMM 1), and Slot 3.
The Black ram memory slots are Slot 2 (DIMM 2), and Slot 4.
To run Dual Channel ram memory, means there are two LIKE ram memory modules ('Stick'), and they are installed in the SAME channel.
This would mean to alike ram memory modules, in both Blue ram memory slots, or both Black ram memory slots.
Since the ram memory modules need to be alike, they are generally purchased from the same manufacturer, and are the same kind.
Running ram memory in a dual channel configuration, is supposed to increase ram memory 'speed', up to 30 percent.
This is Baloney!
May look good on paper, but in actual use in the field it's cr@p.
Actual performance increase is more like 1 to 2 percent.
This has been proven by Tom's Hardware, and many, many motherboards, ram memory, Processors, etc.
So you have 2GB of DDR2 Sdram, huh?
Is it just one 'stick' of ram memory, or are you referring to two 1GB sticks?
If the above holds true install them in Slot 1 and Slot 3.
If not, and it is a 2GB stick of ram memory, be sure it is installed in Slot 1 (DIMM 1)
Install the 1GB stick in Slot 2.
It isn't the same as the 2GB stick.
It is 1GB.
Does NOT go in a dual channel configuration.
(Catching all this? There is NO dual channel ram memory!
It is ram memory that is -> ALIKE, and used in a -> dual channel configuration.
Used in two separate ram memory slots, that support the dual channel configuration.
Sold with the advertising scheme of 'Dual Channel', but really just means the two ram memory modules, (Or four), are -> alike.
1) Same Voltage used
2) Same Ram Timings
3) Same Chip Configuration
4) Same size in amount
5) Same frequency rate ('Speed')
With ram memory in a dual channel configuration, the ram memory modules team up on the task.)
