I have an ASUS A7N8X-X motherboard which suppots 400 MHZ FSB and 1.3 Gig of ddr ram rated at 333 MHZ. However when I start my PC I have a message that my ram is running at 166 MHZ single channel mode. I went to bias and didnt find an option to run it faster than 166 MHZ. Please help me. How can I utilize the true speed of my MB and RAM ? Or am I missing something?
I have 3 sticks 512, 512, 256
not same manufacturer but all DDR 2700

Your RAM should be running the correct speed, 166 x 2 = 333 .

So your fine.

Shouldn't it say 333mhz dual channel during the post? Also does having that stick of 256mb change any of the speed settings ?
Thanks for the response.

DDR = Double Data Rate

So 166*2 = DDR333

Secondly, It is hit and miss having 3 sticks of RAM whan you want dual channel. Firstly, make sure you have the 2 512 Chips in the correct slots to enable dual channel. After you are sure you have DC enabled, add the third stick and see what it does.

No, most motherboards do that actually, they just display the 166. As mentioned in Ned's reply above.

And generally you would rather have dual channel, than the extra 256 MB chip, so if you can't get Dual Channel working with the 256, but works with the 2x512, I would just leave the 256 out.

Wouldn't find support for dual-channel with nForce2 400 (non-ultra).

What processor are you running?

You need 2-4 dimms to keep dual channel enabled, having the odd number of 3 eliminates the option.

Wrong, you're thinking in Intel terms. nVidia's dual-channel solution doesn't combine the two 64-bit channels into one 128-bit channel, instead it spits data between two individual channels like a sprinkler system (or a RAID0 controller). Most of those boards had 3 DIMM slots.

Ah, I didnt know it was varied, I guess it was ignorant of me to assume that because my motherboard works that way, they all do ;)

That board is only single channel anyway. It doesn't offer DC.

You're right, he'd need the standard A7N8X or a newer version of it, rather than the cheaper -X version.
