CPU-NB clock speed for Phenom II is 2000mhz rite?
now I oc it to 2400mhz at CPU-NB voltage of 1.26V
my clock speed for my x3 720 is 3.4ghz at 1.391V
Ram's 4gb ddr3 1333mhz with dram voltage of 1.71V
my question is, is the overclocking of CPU-NB justifiable? the increase in 400mhz will help? cuz i dun rly know wat it does, but i read from some articles saying it will but depends on yr CPU clock speed and all..
its jz so confusing, I heard alot of ppl OC-ing CPU jer for basic overclocking, barely heard of ppl going for CPU-NB speed, so is this necessary? sry for noob question...
ALSO, my temp's idling at 31-33 and at full load 42-43, will CPU-NB speed increase, increase my temp as well?
1.26v for 2400MHz of NB freq sounds fine to me, but ofcoz if it can be lowered by a notch or 2 would be better.
vcore wise, 1.39v for a 3.4GHz clock is slightly high imo, back then (when i was usin 0904bpmw x3 720), i only need 1.34~1.36v for that kinda clock if my memory serves me well. 1.424v can bring me up to 3.6GHz, but ofcoz it could be diff in hw used.
increasin nb freq won't help much in daily task but it does help in benchies/gamin (perhaps, but negligible). generally d higher d cpu clock d higher d nb freq should be. can't really explain (i'm those lazy to google) but from what i read it got something to do utilizin d 6MB L3 cache iirc. in ya case, since u oc'ed ya cpu clock, there's no harm lite oc d nb freq. not so sure bout d capability of ya imc (a.k.a cpu-nb) but those that i've tried max out @ 2500MHz for normal setup @ around 1.3v, any higher just for benchies & d volt are not so friendly.
theoritically more volt/higher clock spells higher temp, & since imc is embedded into d chip, so it's natural to have higher temp when ya imc is oc'ed. but i reckon it won't increase temp of ya chip by a large margin, most 2~3'c for my case. worth it for better results when ur doin benchies...

hope this helps...
