BSOD during bootup, after OC. - Page 2

post #11 of 16
Thread Starter 
Guys, if i can boot at 4.8GHZ, without PLL overvoltage, does this mean i can disable this ? will this affect oc stability?

Also i can boot @1.37 vcore @4.8ghz, does this mean i can lower my vcore to lets say @ 1.40 and get it stable? for now im almost fully stable @1.43 vcore @4.8 but its strange i can boot with so much lower vcore and need quite more to get it stable, or i need to play with settings in order to get it lower?


My settings,



VCCSA Voltage: Auto
VCCIO Voltage: Auto
CPU PLL Voltage: 1.70
Auto PLL Overvoltage: Enabled
PCH Voltage: Auto
VRM Switching frequency: 350
Vcore PWM/Duty Control: Extreme
Vcore Phase Control: Extreme
VRM Current Capability/Vcore Over-current protection : 130%
CPU Multi 48 by all cores
CPU BCLK: 100
CPU voltage/vcore: 1.43v Manual
DDR Voltage: stock volts/1866mhz
CPU Spread Spectrum: Disabled
LLC: Ultra High

Also, VCCIO/VCCSA/VDRAM swithcing/phase control settings? worth to set this to extreme/manual?

Have you disabled LN2 Mode yet?

Internal PLL Overvoltage should be left disabled (not even on Auto) until you absolutely need it. The only time you might need it is if you were able to start exceeding a multiplier of like 50 or more - but even then you might not need it.

Here's a quote from Juan Jose on Internal PLL Overvoltage. Juan Jose is the Senior Technical Marketing Specialist at ASUS:

"This option is specifically designed for D2/Retail Parts and allowing for higher multi overclocks especially when at or exceeding 48x. Additionally, this option can be used if you do not have it enabled and generally cannot boot with a higher multiplier. It is advised to try this option after you have tried all other standard options. This option is not for increasing stability of a OC that can already post and boot into an OS."

(source)

In other words, most of us may never need it. So I recommend leaving it disabled for now.

"Lower" your vCore from 1.37 to 1.40V? Did you mean "increase"? I'm a little confused. However, it's still absolutely necessary to test the stability with a 12-hour run of Prime95's Blend test. If all 4 workers in Prime95's Blend continue running for 12 hours, then it's stable (I'm assuming that you have disabled HyperThreading, otherwise there will be 8 workers).

Being able to boot doesn't mean it's stable.

I recommend the following changes:

CPU PLL Voltage: Auto. There's actually no real need to adjust it for this overclock.

CPU Spread Spectrum: Enabled. Only disable this if you decide to start adjusting the BCLK. The same goes for EIST and C1E.

CPU Voltage: Offset Mode (seriously)

Offset Mode Sign: +

CPU Offset Voltage: to figure out what to set, check your VID in Core Temp or Real Temp (using Core Temp is slightly easier since it's like right there hehe). Any value you enter here will be added to the VID you see in Core Temp. For example: mine fluctuates between 1.3511V and 1.3611V and my Offset Voltage is 0.040V, and this results in CPU-Z telling me my core voltage is about 1.392V, sometimes 1.400V under load (my LLC is Ultra High).


The reason for using Offset is to avoid having your load voltage constantly running through the CPU which also allows you to have lower temps most of the time. For example, the core voltage that is running through my CPU right now is only about 1.04V while my clock is 1.6GHz, so my idle temps are hovering at about 25-26°C. These Sandy Bridge CPUs do an absolutely outstanding job of dynamically responding to CPU load so that we never see any performance loss. That's one of the reasons why I named my sig rig "Advanced Alien Technology" tehehehe.

I looked through the manual, but I don't see "Extreme" as an option for these. Instead, all it shows are Auto, Disabled, Enabled, and even some kind of multiplier for the Switching Freqs. For now, I'd leave all of them set to Auto. My motherboard doesn't have any of these options, but yet my overclock is rock-solid stable.


After looking through the manual very carefully, it looks like the majority of the tweaking options in Extreme Tweaker are for people who are doing extreme overclocks using sub-zero cooling and whatnot. For that kind of overclocking, it can be absolutely necessary to adjust most (if not all) of these settings. However, a more simple overclock like what we are doing only needs a small portion of these settings adjusted.

Wow, thanks for the detailed post...

1. Yes i meant to increase the vcore from 1.37..to get stability at 4.8 but decrease the vcore which i use atm, 1.43 to 1.4.

2.Cpu PLL its good to lower this as far as i know in order to get lower cpu temps.

3. I will enable spread spcetrum as soon as i get back home, but it does change my efault BCLK to 99xx instead of 100, dunno why.

4. Using offset lead me in many instability in the past during idle, so i think i will go on without it atm.

Thanks one more time for suggestions/tips rep +

BTW yes the options are a bit more detailed on ME4 compared other to other mid- range mobos.

Oh, I see it now! In hindsight and when I re-read it, it does make sense now!

Oh, that! Yeah, I heard that too but I haven't acted on it yet. I think I'm just being lazy. I'm also afraid of disturbing my stability.

Oh interesting...

We will figure it out, so don't disable it.

Oh, that reminds me: disable C3 and C6 to avoid idle BSODs and other problems while idling. The reason why you had problems before is because they are Enabled.

Yes i disabeled LN2 mode, disabling C states should be avoit ad far as i know in order to avoid HDD/SSD perfrormance issues, but i will try to experiment.

BTW in order to get your OC settings saved, use the profile options in BIOS it works like a charm, but remember to load optimized defaults, before loading an saved profile, because in some very rare cases it can mixed up with the previous settings.

Thanks for your help, and suggestions

It's just that disabling C-states can considerably affect drive performance, and it's especially for SATA 6G.

I know all about using profiles, but don't need to load the optimized defaults in between profiles. Although, there was a bug reported with previous UEFI versions for the P8P67 boards where switching between two profiles where both have Offset Voltage enabled resulted in the two offset voltages being added together. So if someone were using +0.070V on one profile and +0.090V with another, then that would result in a very high 0.14V. For me, that would result in a core voltage of 1.52V!

Fortunately, I jumped straight to the latest UEFI before doing anything with my board, so I never had to experience that.
