Hi guys,
just a little query, how do I set my v-core on this mobo manually, basically in the bios there is two columns when setting the v-core, one is listed @ 1.35v as standard and the other is listed @ 1.25v current (this is the one I set).Now when I run say prime95 blend test, the volts in Core temp go up to 1.35v, how do I change this to only use the v-core I set??

I checked Cpuz but I think the V-core is borked in the version I have as it dont move from 1.06v, even when I use Prime. Also I note that I can only change the LLC level to auto or normal, when others are using numbered levels, why is this?

Any help on this would be much appreciated. ;)
 
Cheers for the reply,
I took a screenshot to show what I am seeing, even though I downloaded the latest Cpu-z, I still get the same V-core reading!? In the screenie I am running prime95 blend and Coretemp still shows 1.35v, when in bios I set it to 1.25v. It seems the 1.35v is the normal setting in Bios and the 1.25v is the current setting that I set, so based on this I cant change the 1.35v setting as there is no option for this.I cant help thinking that I must be doing something wrong, I wonder if it has anything to do with the GB Easytune software? :confused:

As regards to the LLC, the only options are Auto,Normal & Disabled. I am using the latest F4 bios.

I am assuming you were at 40x - I think you did not read step 11 as I intended :) I wanted you to take a screenshot during the Super Pi run. Not at the end of it. Basically I wanted to see if your vCore was being correctly picked up, and if so if there was any vDroop.

But moving on.

  1. Reset and go into the BIOS
  2. Advanced CPU
  3. Disable all CPU management stuff, just keep all your cores active.
  4. Now we go back to the main overclocking page and up the multi to 45
  5. All the voltages still on auto
  6. F10 and enter and boot into OS
  7. Open CPU-z and run Super Pi
  8. Take a screen during the running of the super pi
  9. If all good then reboot and change multi to 46
  10. Repeat untill your system does not boot into OS or,
  11. your temperature are above acceptable levels 70'C + during load.
  12. Post back here and we will start the final part of the process which is fine tuning.

Ooops sorry about step 11! Right, set multi to 45, kept everything on auto for voltages tried to boot to OS and BSOD straight away "IRQL_NOT_LESS_OR_EQUAL", re-booted and now into windows, should I continue??
 
Current temps in Coretemp are idle @ 40c-44c over the 4 cores. Should I not be concerned with the BSOD? I also ran a quick Prime95 and it failed with-in seconds on 3 out of the 4 cores.

Will I try the benchmark you suggested?
 
Cheers 1Day, the temps taken during the hyper P1 bench were as follows:

Core0=59c
Core1=61c
Core2=59c
Core3=61c
All@ 100% load. The Voltages recorded in Bios were,
V-Core=1.355v
dvid=0.0v
qpi=1.05v
sys agent volt=0.920
ph core=1.05
cpu pll=1.8v

D-ram=1.5v (although xmp voltage shows 1.65v on M.I.T front page at bottom of screen)
All voltages set to auto.
 
No need to apologise, after all you are the one helping me!

Left it at 45x as I am more than happy @ 4.5ghz! Enabled LLC and hard set the voltages, I had already set XMP 1 profile so no change there and have completed Hyper Pi 32m in a time of 8mins +, temps were 2c up on my previous run.

I am now 20 mins into Prime95 and low and behold all is well, temps are 70c on 1 core and 1c under 70c on the other cores(max temps). Got to say 1Day, you def know your stuff and I am well impressed with my results thus far, so thank-you very much!!!!

Not done a lot in the way of overclocking before and I am glad you rescued me before I done something I might have regretted!!

Why is it though that so many people swear by Prime95 & IBT for a stable rig, if your system wont ever get that stressed?? I think you have proved here that they are not really needed.

Anyway, thankyou ,thankyou you are a diamond for holding my hand through this!! Is there anything else that I need to do? Can I for example decrease my Vcore or is this the sweet spot?
 
All going well with my O/C, I have been going by what you said and just dropping the v-core by 1 increment at a time, changed the cpu pll to 1.76 as per your suggestion and I am currently sitting at 1.34v on the v-core and all seems stable. I have been using hyper pi 32m and short runs of prime95 to check temps. You are now my official Ocuk Guru! :D

Coincidentally, I read your thread on your overclocked 2600k and was left quite astonished at how you got such a high clock, until I saw your pic of your LN2 canister! I must say that is quite some hobbie you have there!:eek:

Once again thankyou very much for your help:).
