I'm looking to replace my motherboard. I'm an Asus gal, I love their
boards and won't use anything else. I'm the same about my AMD
Since I have a perfectly good AM2 processor and 4 gigs of DDR2 RAM,
I'm thinking I might stick with them.
I'm considering the ASUS M4A79 Deluxe.
When checking the reviews on Tiger Direct, I ran across this comment:
"AM3 uses three data channels. The ASUS M4A79 Delux only has two
channels. A true AM3 Motherboard uses DDR3 memory wich has three
channels. AM3 is backward compatible to work with ASUS M4A79 Delux.
The ASUS M4A79 will never use all three data chanels of the AM3."
I'm not very hardware saavy, but I do learn . What are the data
channels and do I really care if I'm missing one?
Data is moved around the mainboard between various components via a data bus. There can be more than one. The "channels" you are asking about are data buses, or pieces of data buses.
To move from two channel data to three channel data is like upgrading the highway from two lanes each way to three lanes each way. Traffic will likely flow smoother/faster, whether that traffic is cars or ones and zeros.
Should you care? No. Not unless you intend to upgrade to an AM3 processor and triple-channel memory someday. But if that day comes, you will probably want to replace your mainboard (again) anyway.
If you think that the M4A79 Delux is a good fit, buy it. Don't worry about the data channels. Two channels is good for the processor and RAM you intend to use. -Dave
