FSB overclocking affect on northbridge temperature
Posted: 04 Feb 2008, 15:41
Hi all,
My system specs are below. I find that the northbridge heatsink gets rather hot - almost to hot to touch. Apparently this is normal on this board but I have a 3.0GHz CPU that I know I can easily push to 3.4Ghz without any temp problems on stock standard CPU cooling.
I am however worried that by increasing the FSB to obtain the overclock (333x4=1333mhz to 378x4=1512Mhz) I might push the temps of the Northbridge up higher and run into a problem there.
I guess my question is - will increasing FSB increase NB temperature? If so, an ideas on where I could buy a better NB cooler? The Mobo has a NB fan connection but does not come with a fan.
Also, one last question - When I raise the FSB, it messes the RAM speed up (obviously). My RAM seems to be unwilling to clock much over the 800Mhz even if upping voltage a little (not that I'm comfortable doing that) which means I need to fiddle with the RAM multiplier but the choices are very limited and I end up with say 760Mhz or the next best being 850 (or something like that which fails POST. I am wondering if I change the CPU multiplier from 9 to say 7 to give me more flexibility on the RAM so that I can achieve 800Mhz on the Ram and 3.4Ghz on the CPU simultaneously. Would this work and would a CPU multiplier below 9 slow the CPU down, even if still running the same speed?
