Solved Asus and 3770k OCing

[N00berG00ber]

what up guys, so i bought a Asus P8Z77-V Pro mobo and an i7-3770k CPU. i want to OC it to 4.2 after i get everything installed, however ive never OCed an intel before. only AMD. so how much of a difference is there between the 2? is it just uping the multi and then adding voltage? also, whats the max safe temp under prime 95 load?

You will probably be able to make 4.2 on stock volts.

You could have a look at : Undervolting and Overclocking on Ivy Bridge and also MultiCore Enhancement to make yourself an idea.

awesome thanks!

 

[N00berG00ber]

also i want the CPU to scale volts and speed after i test for stability. i know speed step is one of the options that controls that but what else? also idk if this board had advanced LLC options, but what shoud LLC be on? and what max safe prime 95 temp?

 

[NoN]

You might have to go in bios settings for advanced LLC options (i have it on), then monitor and fine tune with the Asus AI Suite II software (Digit+ Power Control, tab).

alright sweet thanks!

Know what your temperatures are and what's safe.
A cold cpu is a happy one. Monitor your CPU temperatures. We always take the hottest 'core' as your max core temp. Never the lowest.
in my opinion, as well as that of the HWmon software, and Intel specs, these are the ranges for sandybridge.
Green is perfectly safe. Yellow is a little warm but ok. Red is too hot. purple is dangerous. The cpu will throttle and prevent itself from dying from overheating, but you still must keep a good temperature.

0-70 Safe
70-80 Safe. Attempt to lower the temperature
80-90 Approaching unsafe levels
90-100 Dangerously hot

If your CPU ever gets into the 80s, IMO, it's getting too warm. It is ok to allow 80-82 for the 15 minutes IBT takes to run. As a general temperature for any period of time, however, it is overly high. The idea is to have a Sandybridge system which rarely if ever exceeds 70 in normal use. It shouldn't exceed 80 in normal use. If you EVER hit 90, stop whatever you're doing and let the cpu cool to idle IMMEDIATELY. You should not allow the CPU to exceed 85 IMO.

I always try to stay under 70 max (use, ie gaming, etc) temp when overclocked. Please note that your actual use temps (ie, playing a game) will be about 5 degrees less than prime95 and 10-15 degrees less than Intel Burn Test. For example, I get about 55-65 gaming, 70-75 in prime, and 80 in IBT.

ya i just got to read that... thanks!

What c- states do I want enabled and disabled? I know c1e caused some performance loss on my AMD rig so the only one I left on was c6. While my PC is on, I don't need any power saving but when I have it in sleep I do want power saving enabled.

You might want to set like this for being stable:

CPU Ratio ► Desired Overclock (42 = 4.2GHz or 45 = 4.5GHz)

Enhanced Intel SpeedStep Technology ► Enabled

Turbo Mode ► Enabled

CPU C1E ► Enabled

CPU C3 Report ► Disabled

CPU C6 Report ► Disabled

Package C State Support ► Disabled

Internal PLL Overvoltage: Disabled if you want to keep Sleep Mode

And disable CPU Spread Spectrum in Bios AI tweaker tab.

Also set disable in Bios EPU tab

You should tell us or be more clear about what you're doing right now.

We don't really know if you're in the process of O'Cing or if you're just trying to have good settings first with that Mobo!

 

[N00berG00ber]

the mobo hasent even shipped yet lol

since its my first intel rig, i just want a little heads up before i go dive into it. a lot of it is similar, but there a re a few things that i am unsure about:

What is:

1)Internal PLL/voltage
2)ASUS MultiCore Enhancement
3)1-Core Ratio Limit
4)Ratio Synchronizing Control
5)VCCSA Voltage
6)PCH Voltage
7)Hardware Prefetcher
8)Adjacent Cache Line Prefetch
9)Package C State Support

Rite now, alli know is that i want the CPU to be at 4.2 just by the multiplier and i want turbo boost disabled.

 

[N00berG00ber]

ok so reading about C-States, i think im just going to enable all of them since i dont hibernate my PC i only sleep it for hrs sometimes. ill benchmark it and try the c states once i get it up to par.

All i can suggest you now, is to read the P8Z77-V-Pro user-manual from Asus site, there's a good part about the UEFI Bios introduction.

Also read the mobo specs reviews online because they do talk often about that UEFI Bios settings.

So, you can keep an eye on what you will need when you'll have your mobo in hands!

Here's an exemple of Intel z77 UEFI Bios overview:

 

[kbrady1979]

I will post my BIOS screenshots from my Sabertooth in a little bit to give you an idea of what options you can change and what you don't need to change.

I did this at first too and locked in a solid oc but it is better to use Turbo you will see no difference it will kick in and you will be at a constant 4.2

There is a Asus OC guide but that is if you have a Sabertooth or Maximums board i am sure it would apply as well since you are running Asus too http://www.overclock.net/t/1291703/ivy-bridge-overclocking-guide-asus-motherboards

 

[Britton30]

I would not disable Turbo, it will just shorten the life of the CPU running at 4.2 all the time.
Like Paul said I suspect if all you do is manually set your RAM to specs and the multiplier to 42 it will work fine. I have all C states disabled right now and all is well.

)Internal PLL/voltage-Unsure
2)ASUS MultiCore Enhancement-Allows all core to overclock
3)1-Core Ratio Limit- Allows the multiplier to be different to different cores
4)Ratio Synchronizing Control-Unsure
5)VCCSA Voltage "
6)PCH Voltage "
7)Hardware Prefetcher "
8)Adjacent Cache Line Prefetch "
9)Package C State Support ?

 

[N00berG00ber]

i was planning on having speedstep enabled. y is is better to OC the turbo rather then the multi?

do note that i use 2 different powerplans in windows. one that runs the CPU at 2.5ghz and one that runs it at full speed. this is because when im not gaming, i dont need the full speed.
