Hi Guys

I have a new 3570K on an Asus P8Z77-v LX2 board.

I've decided to get it to 4.4Ghz and have followed some guides on the net to turn certain settings on and off and the like.

I've just run 30mins of Prime95 with the following settings:

Ratio Limit of 44 (= 4.4ghz)
Internal PLL Overvoltage - Enabled
Digi VRM - CPU LLC - Ultra High (75%)
- Fixed Freq - 350
- Power Phase Control - Extreme
- Power Duty Control - T.Probe
- Current Capability - 120%
CPU Manual voltage - 1.260

That failed after 30mins.

I then upped the Voltage to 1.275 and it failed after 10mins...shouldn't higher voltage mean it gives it more of a chance?

Anyone got any thoughts on what settings I should use for a quick Oc experience?
 
What error code did it blue screen with? Get "WhoCrashed" to analyse the dump and let us know the error code.

Also Try dropping your PLL voltages to about 1.6-1.7, Ivy (not always) likes lower PLL voltages.
 
Hi pal,

Thanks for the reply. I didn't get a BSOD, Prime95 just crashed is all.

I've got an LX2 board so I'm guessing it's not as geared up for OC'ing as others as I have no ability to change the CPU PLL - it sits at 1.8 (invisible in BIOS) and I can't change it.

I've just stuck it on 4.2 and stress testing it now....we'll see.
 
@CeePeeBee I have a similar board, mines the P8z77-V LX For the Ratio 44 I set this:

X.M.P mode
ASUS Multicore Enhancement = Enabled
Internal PLL Overvoltage = Auto
Digi VRM = High
Fixed Frequency =250 (Higher will heat up the CPU)
Power Duty Control = T Probe
Current Capability = 100%
CPU Offset +0.065v

That should give you around 1.224~1.232v

You may or may not have to add 0.005v to the Offset based on the prime crashing or not. If it doesn't crash try lowering the Offset by 0.005v until it does crash, then raise it by 0.005v again.

What Cooler do you have?
 
Hi pal - I have a Coolermaster Hyper 212 Evo.

Starting to wonder if it's a board limitation as some of the settings people speak of aren't in my Bios (ability to change PLL Voltage etc)

Been running on 4.2 for 15hours on Prime so happy that this is stable.

Might give the above a try. My only issue is that the crash is sporadic...it can happen anytime within 1minute to 3 hours...so it's just time I guess :)

Soddit I've just bounced it and am trying it as I type...let's see how we go. 2 minutes in and no crash - rofl
 
Try using VCCSA to stabalise the clock. This is essentially VCCSA and IO on these boards with one being a multi of the other. Its IO which is IMC volts and rounding is often a memory associated error.

I take it you have done the basics of mem testing the system before you started clocking.

Voltage frequency of around 500 is optimal for clocking power.
 
I won't lie and say I understood everything you just said. I've never really tried to OC a system until now. I prime tested my base system without issues. My 4.2 Ghz OC works without issues for 15 hours or so.

This is on the 4.4. My only changes were to add a 0.065 offset to the core and change the multiplier. Nothing else.

I do have the ability to alter VCCSA voltage but a) I don't know what it is and b) I don't know which direction to alter it :)
 
^^^^ I explained what it is above. On your board its the System agent and Memory controller votage in one. Move it up a couple of notches and test. Top end is about 1.1v on that board so dont go much above this.

If you did explain it, it wasn't very well. You used lots of acronyms I'm not familiar with, apologies.
 
ok, I'm occasionally getting this during the Prime95 tests....

Warning about voltage...it's there maybe once an hour during the prime95 tests.
 
Uninstall that software it is not great at all.

You could also disable the warnings in Probe 2 if you wish.
 
Yeah it is from AI suite...only reason I keep it is to control Fans intelligently (based on load) - I wouldn't dream of doing anything else in there.

4.4Ghz so far passing tests 2 hours in....we'll see how things go.

According to CPU-Z my Core Voltage is at 1.3 (fluctuating) that was with me using an offset of 0.070. Top temps are 80oC which I don't think are bad for air cooling.

Fingers crossed - thanks for the info guys

One thing puzzles me about this :confused: You say an optimal of 500? yet the Minimum on these boards is 0.735v Max is 1.685v Standard is 1.05v and increments are 0.005v
