Conclusion:

After completing the game benchmarks it’s clear that that overclocking the HTT/FSB to increase memory bandwidth on the Athlon 64 does not deliver the performance boost expected.

The synthetic benchmarks show a large difference, but when it comes down to games, which rely on the graphics card quite a bit, you will see that they hardly run any faster, +1-3% at best is all you are going to get. So if you plan on upgrading your system, you might want to look towards buying a new graphics card, faster hard drive, better soundcard, larger monitor, or anything else to enrich your gaming experience. Upgrading to expensive, fast running memory should be one of the last items on your shopping list if you are a gamer.

It all depends on the nature of software. If memory bandwidth is incresed but frequency(MHz or Speed) is same then there will be hardly any difference with regular programs. "Quake 3" shows big difference with High M/B @ same processor speed. Anand's past Memory Reviews has covered this.
 
yeah quake3 scales very good with CPU speed ..... sometime before it was like a CPU benchmark but now people has stopped using it in benchmarking ...
 
So is doom3. it scales quite well with faster memory speed.

EDIT: @Harshal, how do u incr MB without incr mem speed?

@hunt3r... as I get your question... u can try lowering the latencies.... but that will not make "significant" difference in Bandwidth at low/stock speed. Memory Bandwidth will increase when you push the Mem frequency up.
 
I'd read in one OC guide, that there's no such thing as 1:1 memory for A64 systems, as the memory controller runs at the full speed of the cpu. So, the RAM is always running asynchronously.
