*groan of dismay* ...post to me...pleease...

Heh, no. I managed to kill my 2400+, so having the spare 2100+ came in handy.

However, if you are using an NForce2 IGP chipset with integrated graphics, the performance difference between single channel and dual channel memory is huge.

With the NForce2 IGP, the CPU and the integrated GeForce4MX ~420 graphics compete for the same memory bandwidth. Doubling that bandwidth with dual channel will bring the CPU' memory performance back up to very close to a system with an AGP video card and will bring the on-board graphics almost up to the (mildly-lame DirectX7-class) GeForce4MX 420 AGP card in performance.

Using the on-board NForce2 IGP graphics with a single memory channel significantly (>10%) slows CPU memory access and clobbers graphics performance, dropping the NForce2 on-board graphics nearly to the crappy realm of SIS integrated graphics. Of course, you can still lord it over the abysmally-poor integrated Intel "Extreme Graphics".

For use with the IGP, I recommend using two 256MB sticks of PC2700 right from the beginning. You can add a 512MB stick of PC2700 later. Two 256MB DIMMs on one channel and a single 512MB DIMM on the other channel will still provide excellent dual-channel performance. There's not as much benefit in getting PC3200 or faster RAM because you cannot overclock the IGP much beyond 166MHz FSB while the on-board graphics are in use.

I agree 100%. I got the Abit NF7-M with that chip for a replacement board for my AMD XP1900+ only had 1-256meg stick of 2700. As I was only running SETI on it and wasn't worried about graphics. Tyme for a WU was over 5 hrs. Then I stuck a 2500+ in it and tyme dropped to around 4hrs. Finally I went to 2x256-2700 and in dual-channel mode my tyme has dropped to 2hrs 34min. According to Setiqueue. So the dual- channel made a huge difference. Also with the built in AGP 4X-8X slot I can disable on board graphics and go to a video card if I want.

And like Smokin the 1900+ is now a spare. Smile

A spare until you manage to kill one of your chips like I did. Sad

Or one dies naturally..if there is such a thing. Laughing
