Be careful just generally assuming that. I have an M3A78-T, so a relatively new board and my channels are dimms 1+2 and 3+4. The board screen printing and even the manual say it's as you mention, but my own testing has confirmed that not even Asus knows how they set up their own boards.

You gotta do your own testing on your board.

Special case though. in MOST cases channels are set up to be opposite dimms. In your case its different though. I was just saying in most cases its like this but all mobos are a little different.

noobdown

no the reason is you will loose dual channel. use ganged

Here is my Everest Cache and memory bench. It seems Ganged mode increases memory read significantly.

Unganged


Ganged

Its not a case of the options switching you from Dual to Single channel at all.

Its is an option that affects how the memory is addressed by the CPU.

When running ganged mode your memory controller will operate in 128-bit mode. This has the benefit of giving the whole CPU a massive memory bandwidth. When handling one application that greatly benefits from higher memory performance this is the option you want to be sticking with.

Unganged basically will split that 128-bit memory bus into 2 x 64-bit, so you will essentially have two memory buses. Because of this, Unganged is particularly useful If you are a heavy multitasker, as you are packing 2 memory controllers effectively.

It will not force single or dual channel setups. Your memory will always be dual channel regardless of which configuration you choose.

It is simply a case of how you wish your system to be tuned. If you are using your PC for a live audio take, handling multiple tracks, then ganged will benefit you with the higher memory bandwidth.

If you are wanting to do some encoding of some movies while you have a quick blast on CS:S, however, go with unganged, as then one half of the memory controller will be dedicated to each running app.

Hey guys, I've been really sick the past few weeks, otherwise I would've responded sooner. I did do testing and got no where with it. I tried both settings and didn't notice any difference in speed. There were slight differences in the speed that basic office programs opened, but nothing major. So, I believe that OrphanShadow is right, it doesn't matter what setting you choose, dual-channel mode is always enabled.

I had 2x2gb ballistix ddr2-800 CL4, added a 2nd kit, identical - WOW - Vista 64 just loads its up fine ---

will be testing with ganged mode tonight as all 4 banks are identically filled.

Ganged mode is faster for single apps. However, these are quad cores dammit; you multitask on them . Unganged offers the best performance overall.

xp 32 bit will only see less than 4gb but with 64 bit there arn't such limitations

sorry wrong thread
