curious about increasing fsb or multi - Page 3

post #21 of 25
I don't gain any performance going FSB over multi. The only thing that goes up is watts on the meter when at idle. Honestly I lose performance because I can get closer to my max CPU-NB and memory clocks with a higher CPU multiplier.

Also my onboard ethernet will absolutely hard crash at FSB >240. Only way to reset is to remove all electrical power from the mainboard for a couple minutes. Just another thing to watch out for - some boards don't like it so much.

Every rig is different; I just want to point out that it's up to the user to figure out which way is best, not blindly assume clocking the fsb to the moon is the way to fly. After all, the performance of the CPU is the same, the performance of the memory is the same, the cache is running at the same speed, and most everything else on the board talks through the HT link which also runs the same. The saying that the board runs faster when the reference clock is higher is a myth.

? The difference between fsb and multi overclock is negligible in real world applications however, if you get a board set right with fsb (and all related components overclocked) vs. a multi overclock, the fsb overclocked board will outperform in benchmarks, (and f@h- which is basically a continuous benchmark program- how fast can your rig crunch data)

Google "fsb vs. muli" look through the threads - the consensus is its a wash (or even muli is better for less voltage, temp, whatever) - except when it comes to benchmarks. the original question was based on performance. I'm not trying to consider the "everyday advantages of overclocking with fsb versus overclocking with the multiplier for a 24/7 overclock, and what works best"... I'm speaking pure performance (as was the original question). Benchmark numbers are not myths.

Another thing too is that some MB's are very picky when it comes to there settings.For example my MB will not let me change the CAS to 6 on my memory.Also I have hit my wall on a stable OC at the settings that I posted in the other post.For me the OC that I have with 20.5 & 201 fsb is the way I have to go for a good stable OC.Also this is one hell of a good thread and I hope it keeps going becuase the more people share info the more people gain.

First off i set the cpu shutoff temp to the lowest allowable temp(65c on mine),as its not worth killing a processor for higher scores/extra frames in a game...

I would increase fsb to lower latency and increase bandwidth,
run some benches to attempt to prove stability.

Then see what RAM timings i can get,furthering the bandwidth/latency increase,
run some benches to attempt to prove stability.

Then i would see what cpu-nb i can get,
run some benches to attempt to prove stability.

Then increase multiplier,
run some benches to attempt to prove stability.

All options would probably need an increase of volts,but going fsb first Then multi means you can probably keep CnQ on,saving temps and keeping heat down.

End result is a healthy mix of both benefits and a nippy system.
