Hey,

Im Quite new to overclocking, ive read a lot of guides put the numbers together. Felt quite sucessful with my Q6600 @3.2GHz, however i really wanna push my I7 to 4Ghz.

I believe my values are completely wrong, but its stable / idle at 28deg C

My current values for 3.82GHz are :
Multi X23
BCLK 166
Vcore :1.325
QPI/VVT : 1.215
Dram :1.66
QPI PLL : 1.10
IOH Core : 1.10
ICH I/O : 1.50

Ram is running @ 1666
9-9-9-24 : cmdrate 2
 
I overclocked one of those chips with a friend last year. I managed to get 4,2Ghz solid without a very high voltage.
I don't remember the exact settings but I do remember that I could get 4Ghz with a Bus speed of 200 and a 20x multiplier.

Try 200x20 on your chip, leave the ram at stock speed (at least for now) and the rest on auto.

Let me know if it works and by the way what are your temps?
 
Ill have a go with the x20multi and RAM at stock.
My temps are currently:
Core0: 34
Core1: 31

system has been running idle for 2hours
 
The most effective method to overclock your system to 4GHz is to simply change your BLK to 200 and set your multi to 20.

Then set your ram at the desired frequency that the ram can run. You have the option in the bios to determine what speed (frequency) the ram is running. SPD - normally set to auto select and choose what is your specified ram frequency.

Leave all your voltages on auto.

Once you are in 4GHz open CPU-z or Easytune6 (you can clock to 4GHz in OS with it by the way) and make a note of your volts.

Run some kind of stability test and if you pass after a appropriate amount of time. Then you have a stable base to work from.

It is now up to you to fine tune your voltages if you want.
 
No boot with auto voltages for 4Ghz, should i start putting the Vcore?
 
Nothing with Votages 1.2/1.3 on Vcore will try with 1.35.

The ram is sitting at 1200Mhz, lowest i can put it, but at 3.8Ghz it will boot 1600mhz so should i be aiming for 1600?

Mate, on your ram DIMM should be a sticker where you can find the speed at which the memory is rated by default. This is the Speed you should set on the BIOS. On the package of your memory you might also be able to find this number.
Your RAM is most likely 1600Mhz rated but you better check it to be sure.
 
yeah ive got it set to what it says including timings 9-9-9-24. Would it be a good idea to use Load-Line calibration(improve Vdroop directly).

In CPU properties i see:

Intel(R) Turbo boost Tech: Enabled
CPU Multi-Treading: Enabled
CPU Enchanced Halt C1E: Enabled
CPU Thermal Monitor: Enabled

Should some of these be off?

Load line calibration is a double edged sword. While you can reduce your vdroop, you also have the risk of voltage spikes which, if your voltage set is already high, can exceed the max safe voltage of your processor and damage it.

Set it on medium/high if you like. It might help your overclocking. I try to avoid Ultra high unless the voltage at the bios is very far from the max safe voltage
 
managed to get it to boot with auto voltages, Vcore 1.3.

gonna run prime95 and report back with the results.


EDIT:

done the blend test for 10mins 35degrees max and 1.248V max

Test with large FFTs max temp 56degrees 20mins also with 1.248V max

well....congrats I would say. Those are some nice temps, you might be able to push your cpu a little bit higher. For now, run the short FFTs test for at least 2 hours. If you get no errors then you can most likely be sure that you've achieved a stable overclock.
 
Thanks for the help and information. ill run the test hopefully i can try get a little more from the CPU. almost forgot to save my bios setting! Im very happy with 4Ghz going to try trim the voltages at a later date but for now ill run the tests and make sure its stable
 
Max temps hit 59 degrees core 1, and 56 degrees on core2.
Vcore 1.28 tested for 4 hours.
0 errors.

seems stable to me. Is 59 degrees a decent temp?
 
Thanks again for the help, need to update my signature now :). might try for 4.2GHz if the temps stay around 60oC
 
i might try for 4.2ghz too on mine as my temps are <60oC on full load.

problem is dont forsake mem timings for that extrea 200mhz, just tightened my mem timings and i noticed a decent performance increase.
