4770K NB Frequency ?

Would it change/add much to the performance ?

It may get you slighty improved scores in some benchmarks and help with lowering superpi times but for general use and gaming it wont really add any noticable performance.

No harm in trying though, always good to know youve tweaked your setup to perform as well as it can :)

Thanks for the reply, You don't by chance know a safe voltage to shoot for do you ?
 
1.35v max on air, though you may not need to go this high. Its reccomended for stability to keep cache/uncore clock within 2-300mhz of core speed, ie 45x cpu multi, 4200mhz cache.
 
I tested with asus real bench, super pi 32m, this chip of mine runs too hot for occt, p95 etc. Noticed a few gains in scores on those benchmarks at 42x cache, 1.25v iirc.
 
Got it set to 44 at 1.25 and done 10 minutes of AIDA64 etc... and seems stable but I'm apprehensive as I've never overclocked the NB before :eek:

AIDA picked out FA of my instabilities with my 4770K, Realbench 2 for 8 hours is a much better test for temps and stability!
For some reason my 2 R9 280Xs don't like an OC on the NB, I get all sorts of blue screens when I try to enable crossfire! Also 2nd card is at 100% usage even with ULPS disabled, all OK at 3.9GHz (stock), very strange one indeed! Then again, so has my whole Haswell experience!
 
Well I never plan on doing something like Realbench for 8 hours straight so it's a bit of an unrealistic test :D

I have run Realbench so far for 1 hour, AIDA for 1 hour and all is stable.
 
Its because your overclock is most likely unstable. Get core stable first then cache. Don't go over 1.3 volts cache, stay at 1.28 volts or below.
 
More at Jonnygrunge than you.

You can run hours of realbench and hours of aida and still fail prime 95 in mins. 1 hour of realbench and 1 hour of aida is not really what could be called stable. I was 6 hours stable in aida with a 4770k and failed handbrake more or less right away. Note high profile and a 1080P source will max your cpu out. You have got a 4770k so don't run prime95 as I dont want your cpu to die.

you do realise your upping the uncore right in the bios wich will up the NB in cpuz.

depending what your cpu overclock is try to keep the uncore within 2 notches of the cpu core speed.

for 4.2ghz core
go for 4.2 on the uncore
for 4.4ghz go for 4.2 on the uncore
for 4.5-4.6 go for 4.3max on the uncore

the higher you up the uncore the more unstable your overclock will get and the only realworld difference your going to see going past 4.2 uncore is faster winrar decoding or synthetic crap lol

my recommendation stick to 4.2 uncore max. or at the very push dont go over 4.3 uncore.

--------------------------

only people with really good good i7s can get 1/1 core speed to 1/1 nb northbridge speed for a 1/1 match.
