Async vs Sync...

In this thread i am refering to a NForce2 chipset, but you VIA users can probably still get what im tlaking about...

So ummm...running the FSB at 166 and the ram at async(125%) making the RAM run at 374 that would turn out less preformance than if i ran it sync (100%) on 166 and the ram would be running at 332 even with the same memory timings? still less preformance going async huh?

Thanks for your help

On my A7V333, there was never any performance difference whether running my RAM at a higher, async speed or a slower, synced speed. The limiting factor in the system was the FSB, so no matter what the RAM speed was, the CPU could only talk to the RAM at the FSB speed. Maybe the nForce is different somehow though, I don't know.

Ah well that does make sence, i dont see how it could gain preformance when the fsb was bottlenecking it, thanks it makes sence to me now.

Yeah, basically the RAM is waiting for the CPU and is not able to run any faster. Running Synch with a tighter memory timings is MUCH better.

Yep!

Finally people are seeing the light!!!

If this catches on, I won't have to yell and slap people with trouts who run the memory higher than the fsb on AMD systems anymore....woohoo!!!!!
