Right after boot up it did show 4.1 Ghz then throttled down and I thought that was instability due to too low of voltage therefore I raised it to 1.51. Bad and based on an uninformed decision by me). as I was watching it on CPU-Z.
Here is the link to my CPU-Z specs
3. The temps I was mentioning were during a Backup from a NAS to a Raid Array on the Overclocked PC.
I do believe in the computer business I see now why they would rather use C instead of F, Accuracy, as the conversion factor is all over the place depending on what temp range you are dealing with
ie: 0C = 32F which is a factor of x3 whereas at 100C = 212F is a factor of x2. This tells me that C is much more accurate and stable than F readings are.
The Dev learned and respected this info greatly and I thank you for that.
I am not going to fire up the machine rite now because it is almost 90' F outside rite now and just too damn hot. but when I do the first thing I am going to do is drop the voltage back to around 1.40 and see what happens and maybe bump up the multiplier to 120.000 instead of 100.000 as that is what things kinda defaulted to on the original overclock that is displayed in my CPU-z specs....
If there are any other settings and specs you can share I would greatly appreciate it You seem to know your stuff when it comes to this. Most everyone here says that each scenario is different therefore do not want to advise, and I respect that. (I promise I wont hold you to anything if something goes sideways hehe haah)..
OK so those are idle temps in Celsius. Those are pretty high as far as idle temps go - your chip doing no work is running about the same temperature as mine working 100% to the max. With (4) GTX 680's in the same loop.
Speedstep basically is a power saving measure, where the system will throttle the CPU multiplier down when there is no need/demand for processor power by a program or game. There is no sense in having your processor running full bore at 4+ Ghz to run a web browser or a screen saver, or typing a letter in Microsoft Word, right? So the processor waits until it get some load at the lowest step - once it becomes busy at the lowest step, it will bump up to the next notch. Once it gets busy at that notch, it will bump up again to the next notch up. If it is still busy, it will go up. And so on, until you hit your full clock rate (the one you expect to see). Power management can step through all of these notches and back quicker than you can blink.
Now you mention throttling due to temperature being too high - this may well be happening - we will find out when I have you run Prime95, but with idle temperatures like you have, I'm not going to have you do that just yet. I'm certain that you at this point will exceed the absolute limits of the chip and possibly kill it. Excess volts + excess temp + certain BIOS settings can be lethal to the CPU, and sometimes the motherboard - particularly the power delivery portion (PWM/MOSFETs).
So now we know your idle temps from that RealTemp screen shot.
Need to know what you have in your BIOS for settings for BCLK, Gear Ratio, Multiplier, Turbo Boost Ratios, CPU Core Voltage, Memory Voltage, any other voltages you have changed as well.
While you are in there, you may as well drop the BCLK back to 100.0 mhz, and the gear ratio back to 1.0 x - there is little reason for you to be using the base clock to over clock, since you have the "K" CPU, you can do most if not all of your over clock by just changing the multiplier. My "partially locked" 3820 I got 4.8 ghz out of without taking the base clock above 100.00. When you change BCLK, you are not only overclocking the CPU itself, you are overclocking a lot of other things - memory controllers, PCI express interfaces, memory -- many many things are based on this 100.00 base clock value.
Also what waterblock do you have for your CPU, what brand thermal paste did you use, and how much of it?
Honestly a 6C/12T $600 chip isn't a very good candidate for your first over clock. It's a potentially very expensive learning experience, especially at the voltages you've had it at. I mean, feel free to practice on my 3820, I'll just hang on to your 3930k until you get the swing of things.
Seriously though, the more cores you have in a processor, the less you are going to get an overclock overall, because as you have 2 more cores and 4 more threads generating heat in the same space. What will you be using this machine for when we get you stable?
