Quick Question - So I've been doing A LOT of OC tweaking....but realized I left "Long Duration Power Limit" and "Short Duration Power Limit" on "Auto".

How bad is that? Would I be seeing different OC results if I had set this to "Max" ?? Just wondering if I should redo some of my tests....or won't make a difference?

Current Stabilized Settings:

Ratio: x44
LLC Line: Level 4
Offset: -0.005
Max Temp: 80C in Prime95, 85C in IBT
Load Voltage: 1.168

Prime95: Passed 12 hours of (90% RAM) Temps: 76-79-81-72
IBT: Passed 50 rounds (maximum RAM)

i have a question: what is better to raise up for overclock in offset mode, just the offset, a mix between the offset and turbo voltage, or just the turbo voltage?

great job on the guide and the update makes it read a lot easier, nice work!

I've been trying out OCing for the first time over the last few days. I followed the guide as close as I could an think I'm doing ok.

Using i5 3570k and AsRock Z77 Extreme 4 with H100 liquid cooler.

After 1 hour of blend on Prime I was getting 4.5GHz at 1.192v (occasionally dropping to 1.184v). Offset is +0.010 and average temp across the 4 cores was 67°C.

I'll run it again tomorrow and get some screen shots but do these settings look ok?

Can anyone explain this:

This is weird....my load voltage changed...i went in game and had CPU-Z running...the the voltage hit 1.2v...however, votlage was mostly always 1.168 in Prime95. Anyone know what caused this? I also ran Prime95 again..voltage seems slightly higher as well...1.176 or something.

FYI - I had dual monitors...now I am using single. Using GTX 570.

Have not received any emails of late from this thread. I thought it had died, I guess not. Still curious how people are OCing their systems.

I got 0x7E when I was on the step "warming up"...I decided to change the turbo boost back to 0.004v since it wasn't really helping and crank up the vcore, since I had gotten errors saying my vcore wasn't enough according to the bsod. Once I cranked it up, I got 0xFC. Anyone have any idea what that means? It's not even listed on the bsod sheet. I think I'm stuck at 4.5.

i was wondering if raise the turbo voltage is effectively better than raise offset for overcloking, in my opinion raise the voltage with turbo get the system pretty instable despite of the vcore you're using, with linx i got a lot of bsod @4,7ghz just raising up the turbo and leave the offset +0,005. in my last attempt the system restarted after 4/5 linx cycles, no bsod just restarted, so i think i should raise up the vcore again, who has the cpu@4,7ghz could share his own voltages? i mean pll, vtt and so on? llc level? PLL overvoltage should be enable or not?

Any of you guys here is using "Additional Turbo Voltage" ??? I've never try it...and unsure how the voltage adds up with offset...but I read this from the Sandy Bridge thread..

Everything remains the same (app load volt and prime volt), except of course idle volts go down.

If I put offset down by .020 and add additional turbo by .040:
1.088 idle, all other values remain the same.
offset down by .040 and additional turbo up by .080:
1.064 idle, all other values remain the same.
offset down by .080 and additional turbo up by .160:
1.032 idle, all other values remain the same.
So in the end I had my LLC on HIGH and offset down to 0.040 with same volts everywhere (except when idling). Worth noting here is that raising offset by as little as 0.005 now has a large increase on vcore (as it's combined with additional turbo volts).

So I guess it takes Offset into account...I might try this next week.

Let me know how this goes...I'm not comfortable with Additional Turbo Voltage yet...

Were you able to get stable OC without Additional Turbo Voltage before? And only when you started using it...it be unstable?

I made a stable OC with additional turbo voltage:

i5-2500k on Z77 Extreme4

Additional Turbovoltage +0.020v
Offset -0.020v
Loadline calibration level 3

4.5GHz @ 1.344v is the result.

Did 10 runs of linx using all memory.

What you can do it disable turbo boost first. Then find the lowest stable offset by prime95 blend or linx.
Don't forget to make sure 1600mhz is stable as well. To do that you can leave it idle. Or force 1600mhz and stress test that.


When you find your lowest stable offset do this:

Target your favorite multiplier, and start raising the additional turbovoltage.

Done.

My method works pretty well. Only takes little more time. I am going to see how this turns out after running it for one week. I personally think it's better this way.

The only thing you have to look out for is that you want to make a good safety zone also. I have -0.02v as offset and started from there. I know I could take -0.05v. But I think this is safer.

OK that makes sense, I like the approach...I'll give that a try next week.

1 thing though - can you explain "lowest stable offset by prime95 or linx." ?? Doesn't that test load and not idle....

My lowest offset right now is Level 4 with Offest at -0.005...but that is for 12 hours of Prime95 at load.


EDIT: Nvm...you said "disable" turbo boost at first...ok that makes sense...lol

Would you said that using "Additional Turbo Voltage" would just reduce idle temps/voltage but not reduce load temps?
