Did you happen record the max temps it got to for each overclock at all? That'd be useful to see. Great results though, I haven't been able to do anywhere near that low voltage for those overclocks.

You seem to have a few settings there for voltages that I don't. Here is all I see on mine:

These are the same options i have mate, I wonder will we be able to use the same volts at 4.6ghz that 8pack used??

Hey 8 pack, looking at these overclocks I am well impressed with your results.
I had my system at 4.6ghz for a while, but after gaming for 30 mins on battlefield3 the game crashed. So I had to lower my clock to 4.5ghz and all was ok.

I meant to ask in my previous post. Is it safe to keep voltages at one fixed voltage? or is it better to use offset?

Also, I noticed in my Bios under the voltages, there are the following options.

for 4.5ghz
CPU voltage (offset or manual) + 0.020
DRAM 1.5
VCCSA auto
CPU PLL 1.5
PCH ??????? <<<<<< what is this

I also have the AI Suite software you used to do these clocks with, I think I have most of the options available that is on yours.
Is the AI Suite ok to clock with?

Cheers 8 pack

I did not use AI Suite to do the clocking I used Bios. I put AI Suite in the screen shots so forum members could see what voltages I was setting.

I used Fixed Vcore on that clock and I prefer fixed always. Its not more dangerous as you put it at all.

VCCSA always comes in useful when tuning stability.

PCH voltage is the chipset voltage. Leave this on auto unless your having stability issues with multiple devices or graphics.

Do you think the voltage you used on 4.6ghz is achievable on my board? (p8z77 v pro)

This all depends on the silicon you have in hand as well as other component factors too. The CPU I picked here was a random one from the warehouse. I have had CPU that will do 5ghz at almost stock volts and others that will only do 4.6ghz at 1.35 on high end hardware.
 
I use the same clock speed.

Good silicon is if your CPU or whatever component can go higher and at lower voltage than the rest. e.g 4.6 ghz stable at 1.2 and 5.0ghz at 1.4 compared to one that does 4.8 at 1.35 and is 5ghz incapable.
 
ok thanks for the info 8 pack.

to make my cpu the one speed, what do i need to do?
disable turboboost and speedstep?
Also, is this bad for the cpu to stay at one speed+volts?

Chris
 
I was able to lower my vcore using offset to 1.24v for 4.5ghz (medium llc)
temps are 60-65 degrees. not bad like.
i also changed my memory timings to 9-9-10-26-1
cpu pll overvoltage disabled also.
1.5 cpu pll voltage
1.5v dram
 
leave speedstep on and turbo off??
ill try for those timings (although i dont even understand how u think they sound wrong, to me thats like saying " yeh, 101011 doesnt sound right, its more like 10101")

lol
 
Theres one thing certain here, I do trust ya lol

ok so I've made the CPU 1.24 volts and a fixed ratio of 4500 with speedstep on.
I'm now running a stability test in aida64 on CPU and gpu. The volts say 1.200v under load but when idle they were 1.28 or so. How come?
Is LLC required still when it's a fixed voltage and ratio?
I always thought that LLC only took care of voltage when the CPU is under load?

I also amended the timings to 9-9-9-25-1

test running for 10 mins now

I tried setting LLC to auto and vCore 1.24. under load the vCore doesn't change much from 1.24..
is that good? I'm running another stability test under Aida. lets see how it goes.

Auto LLC seems to keep the fixed voltage to around 1.216v.
Seems to be stable enough, I reckon I should shoot for a higher clock like 4.6/4.7.

I noticed theres a new Bios update. might apply that later as well
