3770K Multiplier voltages for 47x and 48x. What are yours? (Ok - I MEAN HELP ME!)

Hi Guys,
Decided to fire some extra effort at getting this 3770K above multiplier 46 stable.

She will do 4737mhz at 46x103 no problem with voltages around 1.28v and bench all night at 4780mhz with 45x105, indeed this week she has been doing with great results. Super Pi 32m / 3Dmark / catzilla / You name it.

However, no matter what I do, I cant get her Super Pi 8m stable on multipliers 47x or higher no matter what i do. (All initial multiplier testing is done on 100mhz bus and 1600 ram)

Also, perhaps worth mentioning is something I personally find a little odd about OC'ing the 3770K, (or this one at least) is that if I get her stable at any speed, I can have too much voltage and make her unstable again.

Example:
4737mhz (46x 103 @ 1.280v) she will pass SuperPi 32m no problem, but she wont at 1.30v.

In the past, I have never had any problem with too much voltage other than heat.
Is this normal For IVY, or is mine odd? I wonder if my leakage is too high and she simply wont run voltages higher than 1.290v at all ad I have tried so far right up to 1.55v in 0.01v steps.

For reference...
Asus maximus Extreme IV Z68
i7 3770K delidded (Never sees above 60C no matter what volts I put in it... rarely exceeds 45c).
Larger than most water loop with external 1260 rad.

Tried all manner of BIOS tweaks, all the usual:


  • LLC optimised / High / Extreme
  • Phase 350 / 400 / 450 / 500
  • CPU PLL enabled
  • C states all off
  • Spread spectrum always off
  • Looser ram timings



Nothing seems to make any difference.
Always the same result - boots to windows fine, but put it under load with higher than 1.295v - dead stop - black screen error. 124. Every single time.

The point of this topic I guess, is to get some feedback, ideas and discussion going and then if lots of people tell me they have had to exceed 1.55v to get 47x, I will try it as that is the highest I have tried. But it seems high considering what I have read on the forums about others experiences.

Another thought I have yet to investigate - can peripherals cause it?

Tried for 5hrs last night. No joy, teh minute I put over 1.3v in this CPU I get a 124 error.

I tried everything from 1.28 to 1.65 in 0.02v steps last night.
I have now retired from this and will try and sneak the 3770k out of my work machine home for some tests to rule out the mobo.

If you have a multimeter, probe Vcore at the measurement point and find out what the board is setting.

The 2nd link was dead mobo.
The C-States thing is interesting though as mine are all off and I use fixed voltage. Will investigate that tonight!

Sorry, Thank you. How damn rude of me.

Thanks Raja, will do.

As an aside, could you take a look at this topic for me mate?

I don't use ROG Connect (it has been a long time). In addition to the advice in that thread, I would make sure that you have ROG Connect plus installed on the motherboard side and Intel MEI drivers as well. If that does not work, just use Turbo-V instead.

Thanks Guys - I didnt mention, but should have, that Turbo V has the same problem.
