That seems good. Though your voltage via that CPU-Z validation is actually 1.4v on LOAD. Don't know what you're idling at.

Lower LLC setting than 3 might give you a lower load voltage, like LLC 4 or LLC 5, and less heat. But you might fail or Blue screen if your on the brink of stability.

I heard 1.425v from the ASuS rep Jose who is on Newegg TV and Hard Forums is generally the max 24/7 safe voltage so you seem in the clear.

I myself am In School, and have virtually no money anymore due to working 1 day a week, so my overclock is a 4.3ghz with a -0.100v offset (yep, a negative offset tongue.gif ). keeps me at 1.240v MAX load with 60C load temperatures.

I may bump up the multiplier and see if I can do atleast 4.4-4.5ghz on this setting or maybe lower the offset to maybe -0.075 to keep stability.

But it's funky because i noticed the LLC is actually VERY IMPORTANT and the offset you pick and the LLC you choose work "hand-in-hand".

i.e. if you choose a good offset (sufficient vcore -0.075v) but your LLC is too low (like LLC 5), you will blue screen.

likewise, if you choose a good LLC setting (like LLC 3), but your offset is way too low (like -0.150), you will blue screen

In summary, you could get both these settings stable by trial and error and experimentation to find -0.075v offset with a LLC3 would be the perfect setting smile.gif

yeah it goes up to 1.41v max (per hardware monitor) but no worries I have an intel tuning plan so if it dies it will get replaced

I only paid $99 for the board so I will give this thing hell!

Many people, like me, have been running on 1.5v with no bad effects.

Kenny, is there any possible way to write about in the overclocking guide, to "test a negative offset?"

I would assume there are users like me, who's motherboard/CPU will default the Vcore on the Overclock very HIGH, and thus have high temperatures for "low" overclocks i.e. 4.3ghz 1.37 vcore with 0.005+ offset.

In other words, in order to scientifically max my overclock, with the least damage to my CPU, I used a negative offset.

I initially used the 0.005+ listed offset in your posts, but it was not needed, since My vcore was already much too high as designated by my board per the overclock.

Just a thought. I
post #296 of 9489
I'm also using a negative offset for 4.3 (-0.030) and 4.5 (-0.015).

I think Kenney wrote the +0.005 offset with overclocking as high as you can go before stopping. From what I've read here you have to have a positive VCore if you go over 4.7 or something to that effect.

I've seen several members here content with stopping at 4.3 or 4.5 ghz and not overclocking any futher.

I consider this to be "Underclocking" but actually that would be a good addition to the guide. I'll add it in shortly.

I'm at 4.5 and quite content because that's a nice OC and the system is stable and cool. And the system is being used by other family members, so stable is crucial, but I always like to get the most out of a chip, what it will give me, and 4.5GHz is what I'm getting from my 2500K on this mobo. I probably could push it further, in fact I have no doubt, but it's been stress-tested by a 14 year-old male for a week now at 4.5 GHz and no crashes and I can live with that. And some gray rainy day when I'm bored and no work to do, which is rare, and no one home, I'll probably push it to see how far it will go.

Interesting quote Kenny!
To me underclocking would imply running a processor slower than the manufacture's stock speed. Anything over stock speed is overclocking, at least it in my mindset. Granted the chip could possibly go another .5 Ghz though.

I'm happy with my 4.5 Ghz overclock. Like you I may go for a higher overclock just for the fun of it someday.

Hi kenny! Can you help me setting my oc without touching the VTT?
I have set my VTT to 1.31v which make me stable running 15mins of Prime FFT in custom 1344 & 1792 respectively.
these are my settings
multi - 45
speedstep -enabled
short - 250
long - 250
core current - 250
spread spectrum - disabled
dram timings - ram's default 999-24 1N ; 1600mhz

vcore - offset - .0035v
dram - rams default - 1.529v
pll - 1.709v
vtt - 1.31v
c1E - enabed
c3 c6 package c - disabled

i've read some 2600k oc guide that setting VTT higher than 1.15v is NOT a good IDEA. Any suggestion, getting my oc stable again without touching VTT?
thanks! smile.gif
