I am planning on buying new memory for my m2a-vm hdmi i currently have a 2x1gb running at 266 mhz running single channel and was planning on buying 2x1gb 800 mhz dual channel. Will i see any difference? is it worth the upgrade?

Single vs dual channel is dependent on your motherboard/memory controller. If your motherboard can't run dual channel now, getting dual channel memory still won't help. Besides the benefit of dual channel is very minor.

The dual-channel configuration alleviates the problem by doubling the amount of available memory bandwidth. Instead of a single memory channel, a second parallel channel is added. With two channels working simultaneously, the bottleneck is reduced. Rather than wait for memory technology to improve, dual-channel architecture simply takes the existing RAM technology and improves the method in which it is handled. While the actual implementation differs between Intel and AMD motherboards, the basic theory stands.
That mean see you will get a better performance going dual channel.

Edit Yes your board does handle dual.

It will be a huge difference, just make sure that your motherboard is compatible with the memory you are planning on buying.

Huge Difference = "< 5%" on memory benchmarks.... which means less than 1% real world application impact.


BTW, if you are running DDR2-533 RAM with DDR2-800, any additional memory will run at the lower speed as well (unless you overclock).

I really don't think so, have you tried single channel? I bet you there's not more than 5-7% on average between SC and DC.

If there is a benefit or not, well it certainly is. However I wouldn't call 5% a huge difference, but it's there. My take is that you'll gain much more performance by buying a 2x2GB kit for a total of 4GB of ram, dual channel or not.

If you are still in single channel, it might be time for an upgrade.

In your case, $500 could provide outstanding improvement.

i was planning on removing those ram modules but if for example if i put the 2 800 mhz modules in 1 set and put the other ram in the other set will it all run at 266 mhz or will the it make the first set run at 800 and the second set at 266
