Wrong. All you have to do is find your lowest voltage with IBT, then find your lowest with Prime. The differences are huge. IBT is good to check your overclock should your AC go out and that's about it.

hmmm my first time overclocking
At first, after I read the guide I just put it to 42 and stock vcore. Tested and ran fine

Today I put it to 45 and 1.25V (following the graph in the guide)

Temps are 66-74 in Prime95 for a few hours. Is this normal or above average? seems like 4.5ghz wasn't hard at all.

What would you do next? best step? Lower my Vcore until stable or keep increasing clock and vcore until unstable? I guess that's the whole point right, to go to failure (and staying within 1.3-1.45V, according to the guide). Do you guys try and avoid going up to 1.45V?

temps look normal to me.
Start doing what I am doing. Set PLL to 1.55 and find your min voltage. if not stable and get near your current voltage raise PLL a little.
Save it, then shoot for a higher OC.
I am working on 4.7 right now. Was at 1.55 PLL and 1.27 voltage but I got a x124 error when I checked it this morning. trying PLL 1.6 now.

Why not just go toward 5.0ghz and higher vcore first and then when you're stable, micromanage getting lowest Voltage?

My results:

338

Vcore: 1.20v (Batch: L204B410)
LLC: Turbo
CPU PLL: 1.55
Cooling: Kuher 920 /w 2 x GT 1150RPM (Ambient temp: 25c)
post #336 of 3800
my results - 3770k - can't remember exact serial L206A9 or something - seems an early one ?

3770k
Maximus V Gene (great mobo)
16gb Samsung VLP (running at 2000 CAS11 - have had them running at 2400 but testing for stability atm)
GTX480 SOC

DOES get HOT though when benching/stresstesting - up to 95C - but in normal usage doesn't go above 75C even when video encoding - so I'm happy

I just got my 3570k setup on a ud3h underwater. Does anybody know what good bios temps are at stock clocks? I'm doing 33-35c atm but I'm fairly certain there's air in my loop still.

Some revised guidelines based on the x58-x77 platform.

BCLK It is not recommended to raise this value, although increasing it slightly may allow a squeeze of around 100mhz.
Keeping this at 100 is akin to locking PCIE frequency to 100 in older chips as the 2 values are now linked.

Raising it beyond 3-5 over 100 can cause data corruption of HDDs and flash drives or system instability.
Lowering it by 1-2 or up to 5 points does not carry the same risks although may cause instability aswell, it has been suggested that lowering it can possibly net better clockspeed value of vcore by allowing a higher multiplier at the same voltages.
Adjusting BCLK either way reduces performance of SATA devices, and lowering BCLK can certainly slow down many devices so it may well just be best to leave it at 100 or atleast keep adjustments very minimal. Personally I would very much prefer to adjust voltages and stress test with cooler ambients if I really wanted an extra 100Mhz.


VCCSA like PCH should not be touched and shouldnt affect overclocking at all although it is on the same die so cant see why lowering it shouldn't lower temps either idle or load.
Raising it is a no no.
lowering it theoritically should lower temps of some sort but might not, People have done 0.85V instead of 0.925V


Lowering PLL supposedly allows a lower vcore, interestingly it has been suggested to also allow a higher VCCIO(VTT). Asus has said that raising it can remove an OC wall although it should not exceed 1.9v, typical voltages are: 1.5, 1.55, 1.7, 1.75, 1.8, 1.89.

VCCIO is the internal memory controller, ideally it should be within 0.5V of RAM Voltage. Typical range is 975V-1.19.
Lowing this should lower CPU temperatures or allow for a lower vcore.
It is possible that PLL and VCCIO need to be balanced in a way that raising one allows the other to go lower and visa versa although this may not be true.
The less RAM (Both modules and density) you have the lower you can go with VCCIO.

People have reported different outcomes from usage of VCCIO and PLL, either needing to lower or raise them, seemingly contradictory, the way they are related seems to conclude VCCIO, PLL, and VCORE are all reliant on each other and the adjustments are different for everybody because some people need to lower one or more of these values or raise one or more of these values.

Is your LLC set to Extreme? I think that happened to me at Extreme, setting LLC to Ultra High works great.
Here's how it looks at idle:
402

What's your VID at 4.5? Use CoreTemp to find that out

4.6ghz at 1.165v on air I have to say this mobo is amazing.
on Prime i get 72c~ max
but IBT i get 82c max
I'll probably try 4.8ghz later
batch: L204B343
I'm also on bios 0262 probably i'll update that to 0701 after tomorrow.

Could you please share your settings?
