Each chip is different. I could say 1.35v for IMC and then you could need 1.45...
Other settings leave on auto. No need to touch them for that OC.

So what would be a good starting voltage for the other ones. I'm having issues with voltages jumping around, so i'm trying to get all the voltages I can set to be something specific. Right now i'm having to set my cpu voltage way high because it keeps changing. its about .05 v under what its set in the bios. and it gets lesser while under load and higher while idling.

Makes no since!

 

Cpu Vcore changes because it's what Intel designed it to be, it's called Vdroop. You can avoid that enabling Load Line Calibration (LLC). But you won't follow Intel Specs using it.
I would start with 1.35 Vcore/ 1.35 IMC, and not touch anything else (well RAM to the native volts)
And then start testing, voltages jumping around it's common at least on Vcore.

LLC was enabled. set at 1.325 in bios, while idle vcore is 1.296 and while under full load 1.28

with LLC disabled however same 1.325 bios idle vcore is 1.280 and while under full load 1.208

Any solution to this.. All my voltages are manually set now, whole thing isn't stable yet but its stable enough to run p95 for a few minutes.. I don't know why its taking so much voltage..

 

You might want to start first with 4 Ghz. 200 BCLK 20 Multiplier 1.35 Vcore 1.35 IMC Leave LLC Enabled. As I see you got Mushkin blacklines, I recommend the following. Load the XMP profile, and then change the BCLK and Multiplier to 200 and 20. Then adjust the Vcore and IMC to what I said. Make sure you also select DDR3-1600 not 2000. Check the whole thing with 4 Ghz and those voltages and see if it's stable 50 LinX/IBT passes.

 

what is the XMP profile?

 

In the bios, where you can select Manual DOCP etc.. theres something called XMP profile.
Ai Overclock Tuner should be the section.

I thought that was a preset overclock?

 

The XMP is not a preset overclock. Well it is but what it does is load the MEMORY optimal settings, and AVOID overclocking your cpu.
Since you can't run 1600Mhz memory with a 133BCLK processor, what it does is lower your multiplier and get your BCLK higher so the ram runs at it's speed.
But I use that to set voltage+timings and then change BCLK/multiplier.

I'm not sure how this helps? I don't seem to be having any problems with the ram, just voltage problems. my cpu will run 4.2 easy it just takes a lot of voltage in the bios only to show up as 2.8 in cpuz. for instance to get 2.8 it has to be about 1.35 or higher!

 

I'm not sure what you want then...
Max Vcore is 1.4V and max VTT is 1.4V as intel specs.
Loading the XMP profile will load the correct timings and correct voltage.
Then go for the rest of voltages.

 

hmm. i think i'm about to just give up and settle for something slower. its after i pass 4 that i start having problems.

 

If you want I can help you reach 4 Ghz stable, so you get the basics of this, and then you can try moving into higher.

Its like I understand the basics but i don't know why i have to use so much voltage! My temperatures seem to be the biggest problem.

 

Because every chip needs different voltage for the same clocks. You can have a very bad chip and need 1.4v for 3.8 Ghz while I can 4 Ghz with 1.30.
If you want to know how "good" your processor is, set everything to default, no power saving features, boot into windows and check with CPUZ the cpu VID.

What is the VID? And how can it help me? I looked for a VID in cpuz and couldn't find one..

 

VID is core voltage. It should be reported by CPUZ

Oh ok well after loading setup defaults and running cpuz i get .864 for core voltage. idle.
under p95 i get 1.088v

and a load temp of 50 with a idle temp of about 30

is this normal?

 

The temp looks normal I think. But the voltage is good I think. I think you should be able to reach 4 Ghz with 1.35 Vcore if not less.
What speed / voltages did you test so far?

Its mostly been 4 -- 4.2 with voltages in the bios ranging from 1.3275 to 1.365
its in cpuz where i get frustrated. i have such a huge voltage drop from the bios to cpuz. even with llc enabled.

i was wanting either 4 or 4.2 ghz something even. but neither seems easy to reach without high voltage and even higher temperatures.

 

1.32 is not high voltage for 4 Ghz, whats your IMC/Vtt voltage?

my imc/vtt voltages are set to auto because i don't know what they do or how to set them. also that gives me to many different possibilities of problems. I like being able to just say well i'll give this more voltage. not having to try and decide which to give more voltage.

And also it's not that 1.3275 is high its that I can run 4.166 ghz with 1.264v vcore under full load in cpuz but its set much higher in bios to get that low voltage.

I'm still new to the whole OC thing but i understand the very basics.

 

Well your motherboard it's not very high end so that could be Vdrop + Vdroop.
I won't recommend IMC on Auto. Try 1.22 fixed and make some IBT runs.

Alright so I tried that. I had a speed of 4.017 (21x191) vCore in bios was set at 1.325 and IMC was at 1.22. While idle vcore was 1.296 and when IBT started vCore went to 1.272. Minimum temperature was 44 and max temperature was 84. It did however complete all 5 runs on Maximum.

 

Are the temps better than before or worse?
