Setup: i5 4690K - GA Z97X UD3H BK - Hyper evo 212 - Corsair Vengeance Pro 8x2 (2400Mhz)

Stock - on full load - Turbo 3.90Ghz @1.139 v

OC - 4.2Ghz
VRIN - 1.800v
VCore - 1.200v
CPU Ring - 1.200v
XMP = Enabled
Manually set Freq - 1600MHz
Manual DRAM Voltage - 1.500V

This setup is stable, with this OC above, full load temps after 30 mins - under 55C
Now I am trying to OC further, but no matter what Vcore voltage I try it not stable at 4.3 or above, am I doing something wrong here? or should I check for other settings? I think I am maybe missing a setting here and there, because it just does not want to OC over 4.2.
I have even tried 4.3 @1.285 vcore but just before 10 mins stress testing in ETU computer just freezes.

4.3 @1.225 - ETU stress test - PC Freeze within 10 mins
4.4 @1.285 - ETU stress test - PC freeze within 10 mins
4.5 @ 1.30 - ETU stress test - PC freeze within 10 mins
Here are my BIOS settings if experts can take a look and suggest how to go higher with my OC

Appreciate some advise/suggestions from other members

HWiNF064 Logs
OC_42.csv 77k .csv file


The guys here have already given you plenty of excellent advice / suggestions thumb.gif

One thing from me, as well: do not post your HWiNFO64 .csv file. Instead, post a screenshot of the Sensor panel (window), where all the important values (temperatures, voltages, fans, etc) will be clearly visible. Download the latest stable version of HWiNFO64, which came out a couple of days ago.

Finally, another tool which you could take in consideration is the x264 Stability Test v2.06. It can be found on the 1st post of this thread.

Good Luck smile.gif

What is the safe voltage offset for vccsa , digital and analog cpu V
+ 0.300 (1.150vccsa) and + 0.300mv for analog and digital AO is safe ?
Why more vccsa, Viod, Vioa give me more stabyliti with low vcore? I use 4x4 ddr3 1600 set to default 1600.
Thanks!

+0.3V VCCSA should be safe, but it's excessive and could prove dangerous in the long run. +0.3V VIOA/D is too much, on the other hand. That's over 1.3V. I wouldn't go over 1V for VCCSA and 1.15V for IO.

These voltages are needed for when your stability is getting compromised by the IMC for whatever reason. Be it fast memory, a crappy IMC or both.These stabilize the IMC so that you don't have to force higher core voltage to get it stable. And I guess having 4 sticks of memory pushes things similarly to faster RAM.

Disable Turbo Boost Technology and set your CPU Clock Ratio manually. You can enable adaptive later after you find a stable OC and its voltage.

Set your vrin to 2.000v. You can test and lower this after you find a stable OC.

Set LLC to Extreme for now and change when you turn adaptive on later if you feel like it.

Set your windows power to extreme performance if you haven't yet. You can still set the minimum processor state to 5% to get it to downclock, or you can wait till you enable adaptive voltage when you are that step.

You might want to try different tests. I start easy and work my way to harder ones. I run a quick cinebench, then realbench stress for 15 min, if that passes I run OCCT:Linpack for 30 min.

Your temps are really good, you should be able to eek a little more out. Once you get a stable higher OC and the voltages try to raise the uncore and retest, then you can lower the input and ring voltages if you want to. I'll try to find the video about re-enabling adaptive voltage on GB mobos, or I can walk you through it later.

Good luck!thumb.gif

First I want to thank everyone for their input.

So, after 5 hours of playing around, little by little with settings, I was able to get stable 4.5Ghz @ 1.265 VCORE on full load, tested with cinebench65, Intel extreme tuning utility 45 mins, temps around 60C (Never went over 65), with adaptive voltage

Current stable setup:
Uncore 40x
Turbo boost - auto
turbo ratio all 4 cores - 45x
C1E - Enable
C3 - Enable
C6/C7 - Enable
EIST - Enable

Core ratio - 45x
VRIN LLC - High
VRIN - 1.800v
Vcore - 1.265
VRING - 1.200v

Memory
XMP - Enables (Profile 1)
Rest is all default from XMP

I still think that temps are around 60, this chip should squeeze out higher OC to like 4.6-4.7Ghz. But now no matter what I try for 4.6Ghz it is not stable and I am stuck again.
for 4.6Ghz setup i tried:
Uncore 42x
Turbo boost - disabled
turbo ratio all 4 cores - disabled
C1E - disabled
C3 - disabled
C6/C7 - disabled
EIST - disabled

Core ratio - 46x
VRIN LLC - Turbo
VRIN - 2.000v
Vcore - 1.300
VRING - 1.200v

Memory
XMP - Enables (Profile 1)
Rest is all default from XMP

So, any GURU/Experts can suggest where to go from here in getting higher OC, I have played with Vcore and Uncore , but it would load into windows, within 10 mins on XTU it crashes.
Looking forward to hearing from you guys.

Much Appreciated guys!

Probably needs more vcore.

My chip needs 1.26v for 4.8GHz, but aprox 1.33v for 4.9GHz.

The voltage requirements start getting pretty step towards the end.

With +0.300mv i give 1.15vccsa.

Set +0.200 vcssa and VIOA/D i testing stable 4.9ghz with 1.31Vcore (1.307 in cpu-z)
Input V 1.900
Cache V 1.15 and x40

I have a similar situation...

Try 5.0Ghz, mine takes 1.498v...

It appears, there's a voltage wall, somewhere after 4.9GHz, at least on my delidded 4790K...

I can't find stability with under vccsa Vio Via +0.200mv. I use +0.250mv...
How is safe this vccsa Vio Via V?

My guess is not very. I say if you need that much IO and SA voltage for 1600MHz memory, you're doing something else wrong. Maybe try setting your DRAM voltage to 1.65V if it's lower? Or add a bit of vcore or vring or vccin? 1.28V VIO seems quite excessive and I wouldn't trust it for everyday usage. Hell, I'm reluctant about going over 1.1V on mine.

VIO in HWmonitor and AIDA64 is with name VTT ?
