Hi

My brother has 2x256mb in his A7N8X-DLX and now he wants more memory. Is that possible without losing dualchanel mode ?

AMD 2500+ @2145.92Mhz - Volcano9 - A7N8X/DLX - Corsair XMS3200LL 1024MB - GF 3 TI-200 - C: = 2x WD Raptor 10000rpm RAID 0 - D: = 2x WD Caviar 200Gb 7200rpm SATA RAID 0 - Hiper 420w.

nForce2 chipsets do dual-channel as two separate channels (rather than the normal combined channels of most chipsets). So it is possible to do dual-channel with 3 modules on the nForce2.

but it has to be same type of memory ?

AMD 2500+ @2145.92Mhz - Volcano9 - A7N8X/DLX - Corsair XMS3200LL 1024MB - GF 3 TI-200 - C: = 2x WD Raptor 10000rpm RAID 0 - D: = 2x WD Caviar 200Gb 7200rpm SATA RAID 0 - Hiper 420w.

Nope. You can have different modules. Make sure the new one is rated at least as fast (speed and timing) as the others. If it's rated faster, the board will slow it down to the speed of the others, since the entire bus runs a single speed.

I would like to add to his question... I have the same MB as him and some of the same components... I am currently running a stick of crucial Ram Pc-2700 512mb CL=2.5 2.6v... I just ordered a stick of crucial ballistix ram PC-3200 512mb CL=2.0 2.8v... now should I up my voltage in my bios to run at 2.8 for the memory or should I leave it at 2.6?? Also, is my ballistix ram going to now run at 2700 speed with a CL of 2.5???

2.7volt is what I use, do not go over 2.8

Use as little as it takes for stability.

so if I up the volts to 2.7... is that like slightly overclocking the 2.6v memory??? and also what does that do to the ballistix since it is rated @ 2.8v??? also, what happens if I have 2 sticks of the 3200 and one of the 2700... does the whole system still slow down to 2700?

yes of course, 2700mem cant run at 3200 but 3200 can run at 2700.

Not only will your entire system go down to PC2700, it will also go down to CAS2.5. I also recommend upping your voltage to 2.7, maybe even 2.75.

not entirely true , many of todays pc2700 modules can
run at pc3200 speeds with a voltage bump and relaxed timings
