Overclocking CPU for better single core performance, how?

[Laurysss]

People say that with north bridge overclocking you get better single core performance. Do i have to raise the bus speed (default 200) to do this "north brige" ocing?

whut.... OCing in general gives you better performance. It just so happens that the multiplier is the most stable and won't cause Windows to freak out.

OCing is the same performance benefit whether it is NB or multiplier. But multiplier is safer and more stable, as well as easier.

I dont think you know better than that guy -

Jay is weird. In one of his videos from not too long ago he said that overclocking his cpu a little bit by using the FSB made Windows crap out and Nvidia's drivers not work properly. Which can happen often.

 

Personally I would just stick to the multiplier because it won't break Windows and it still improves performance. I'm going to assume to around the same degree as changing the FSB, clock for clock.

I still want to test it out. What thing to i change? Some people say that they were ocing a year with FSB and  everythings ok. Whats the number i have to change? That one that Jay changes?

There are no benchmarks to prove what he says is true. Very few people OC that way because it is 100x more difficult to get the CPU stable.

It may get a little more performance like he says because it also increases your memory frequency. But you can always OC your ram separately from your CPU multiplier.

NB has nothing to do with single core performance, If you want maximum single core performance then you can disable all but one or two cores and just OC those cores. 

 

An FX-8350 hit 8.67GHz on two of it's cores, however was beat by an A10-6800K at 8.2GHz, because the A10 was running 8.2 on all four cores.

It's very different between AMD and Intel. AMD chips can be happy to like 300 on the bus (basically lga1156 ocing)(as long as you balance HT and whatnot correctly). Whereas on Intel the base clock will indeed cause stability issues when you start messing with it.

OP I think Jay meant bumping up the HT link can increase core performance. I had no difference when getting 4.3ghz with a 287 base clock @ 15x mutli and using the standard 200 with a 21.5x multi.

The easiest way to get a boost in single threaded performance is by using Intel turbo boost, provided that your CPU supports it.

 

Edit:

There's also an option like this for AMD CPUs as well.

On AMD it's usually automatic. I don't have my 8350 OCed right now because I need this PC to be stable right now and It goes up to 4.2 GHz from 4.0 GHz just by itself. It's not much but it's all I'm willing to push it ATM.

Still a performance gain so it's all good
