Overclocking a q6600

[scorchisio]

Just got a 5850 yesterday and im told a q6600 will bottleneck it, is there anywhere i can find a overclocking guide or is it not worth doing?

 

[bigsharn]

There are no guides, just be careful, do it in stages, run CPU Burn after every stage to check the stability

If you don't want to run any risks... it should be possible to run the CPU at 3gig which would be the minimum to not bottleneck the 5850 - without adjusting the vcore - just change the FSB to 333 or 334, add +0.1v (i.e. 1.2 to 1.3) to the northbridge and maybe the FSB and it should be good to go - obviously give it an hour or 2 on OCCT and a few passes on the intel burn test to be sure.

Exact settings will depend on your motherboard and the VID of the CPU.

over clocking it by 15per will be ok but taking it to higher ends will definately be bottle necked

I read depending on chip type bottle necks shold be very small if you aim for 3300mhz in general

Apologies for hi-jacking thies thread, but what is the difference between vcore and northbridge?

 

[Rroff]

Vcore is the voltage thats applied to the CPU, the Northbridge is a chip thats seperate from the CPU and helps the CPU to communicate with the rest of the system and has its own voltage.

To over simplify - when you increase the CPU speed by increasing the FSB speed - it makes the northbridge work harder to keep up with communications over the FSB to the CPU - meaning it needs more voltage to do its work properly as it is itself overclocked.

Thanks, I've learned something I didn't know. I have this chip myself at stock speed - I'll give this a go myself.

edit: nm couldn't get the text alignment working

that processor shouldnt bottleneck that card, the cpu isnt that old and it is quad core, some dual cores would probably bottleneck it

Remember that most games dont take advantage of dual core cpu,s let alone quad core.
