Anyone know if 1.3411v is too high for 4.3GHz?

I would say yeah, you should be able to hit 4.5 /4.6ghz, have you tried increasing the multiplier and leaving vcore.

Like I said visit the Sandy Stable club where over 130 member's have provided details of their overclock. I compiled a spreadsheet with different sheets that has the data that may be useful to you. Come check it out.

Hi guys,

Can you please help me out. My Chassis Fan 1 header on the motherboard seems to not be providing enough voltage on my week old motherboard. I would like to know if you guys are seeing this issue or not.

I have two 200mm fans. One on Chassis 1, the other on Chassis 2. The chassis 1 fan reads around 490RPM while chassis 2 reads 741RPM. This is at idle.

If i remove the dynamic fan control option, chassis fan 1 will only increase to 700RPM while chassis fan 2 will go upwards off 1000RPM+. I have tried a 120MM on chassis fan 1 and it still runs terribly slow.

I am about to return the board and get a new one if this is not normal before my 15day period ends. So basically, do your motherboards give equal fan speed for chassis fan 1 and 2, or is this normal?

And yes, this is how it reads in the BIOS also, so its not an asus software issue. Also I have tried to remove chassis fan 2 to see if it was a voltage distribution issue, but #1 still reads the same.

On P8z68-V Pro motherboard.

Thanks guys!

It says that the "T Case" is 72.6°C. The initial proof is in the term "T Case". The "case" is the metal part that you can see; the cores are inside. More proof follows after the following definition of "T Case".

On the old version of this Intel page I linked to you, they used to have a definition for it, and it was as follows (it used to be called the Thermal Specification, but now it's just "T Case"):

"Thermal Specification: The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for that processor. It is measured at the geometric center on the topside of the processor integrated heat spreader.

For processors without integrated heat spreaders such as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The maximum junction temperature is defined by an activation of the processor Intel® Thermal Monitor. The Intel Thermal Monitor’s automatic mode is used to indicate that the maximum TJ has been reached."


Notice that it says in the first line "maximum case temperature". Also notice that the Thermal Specification (which is now known as the "T Case") is measured "at the geometric center on the topside of the processor integrated heat spreader". This means it is measured at the same place where we apply thermal paste which means it is not measured at the cores.

So if the maximum case temperature is 72.6°C, then how hot do you suppose the cores would need to be in order to make the case become that hot? On average, about 20-25°C hotter!

The Thermaljunction Maximum (the Tj. Max) is the maximum safe temperature, and for the 2500K and 2600K it is 98°C. That is exactly 25.4°C hotter than the T Case.

Further proof: most people who are overclocking the 2500K and 2600K are exceeding 72.6°C without any problems whatsoever. This is because their temps are still very safe since they're still well below 98°C.

Finally: look at Real Temp. It shows the "Distance to TJ Max". The reason why it shows this is to be able to tell at a glace how far away you are from the maximum safe temperature as specified by Intel.

So if 72.6°C were the maximum safe core temperature, then most of us here would have killed our CPUs a long time ago.

Thanks Cables appreciate it.

Right now I'm getting BSODs not when im an hour deep into a stress test, but when i idle after it. I think i have to turn down all the power saving jazz.

Or maybe just go back to manual voltages.

Hello everybody,

I came across this thread/club while searching a solution for my problem.

A couple of days ago I restarted my computer, and it wouldn't ever turn on again.
I have tried everything I can think of in order to make it boot, but it just won't.

It goes like this, when I power on there is a short burst of power going through and the fans all spin up during these milliseconds and then the power dies.

However if I unplug the 8-pin 12V connector the power stays on.
Also the board indicates power to the board at all times.

So I came across the voltage bug mentioned in the original post. Is this what happened here, are these symptoms typical?

I was pretty sure it was a faulty board before entering this thread, but now it might swell be the CPU that is faulty?

What do you guys think? Thanks!

Edit: Oh right, I forgot to update my system specs. I'm using a i5 2500K.

Believe it or not, all you have to do is change the settings for "CPU C3 Report" and "CPU C6 Report" to either "Auto" or "Disabled". I mean, if they're set to Enabled right now, then set them to Auto. If they're already set to Auto, then change them to Disabled.

As for CPU C1E and Enhanced Intel Speedstep Technology and CPU Spread Spectrum, they should all be left set to Enabled.

Changing the setting for both C3 and C6 will cause the idle voltage to be slightly higher which will cause it to be just high enough to avoid BSODs while idling.

I have a p8z68 v pro and I've installed the 24 pin power to the mother board but the other end has a shorter connection with another 8 pin attached to it now do i leave that out of the power supply or plug it in?
Much appreciate any help thank you.
Sorry the power supply i have is an ax 850 thankyou.

quick question, when running Prime95 to test stability what option should I use? i've been using the "in place large TFFTS" (or whatever it is) because it says max power / heat.

thanks
