Here you go. Change the extension from .jpg to .bat and put the file in the same directory as the regular x264 test

Crap, people, what are AI Voltages supposed to sit at again? @Cyro999, I'll upload a couple of screenshots shortly which show you the differences in reported voltages between stock clocks and overclocked clocks. The sensor readings are fairly different to my nominated values

Stock voltages before any I/O or SA offsets are applied (Click to show)

Actual applied voltages as measured at the sensors (Click to show)


You can see that my stock SA Voltage is 0.856. If I nominate a 0.010v offset to this in my BIOS, it results in a 0.016v increase (for a total SA Voltage of 0.872)

I'm not going to keep it at that 24/7 though. I killed my Ivybridge, so i'm probably going to keep the core voltage at 1.2 adaptive.

1.325vcore isn't really aggressive or at all dangerous in any kind of short term (maybe degraded a few hundred mhz in 4 years - we don't know) but i wouldn't use adaptive unless you want to monitor it for some days and with everything new that you to do make sure it's not rising higher than you set

This is why i want a DMM - i'm completely blind here on gigabyte, there's no indication whatsoever of what the voltages are, you can only offset, with the added clause that maybe by adding +0.1 you are undervolting because of how the automatic rises work (which sucks)

changed things around, since I know 4Ghz is my limit for now until the Liquid pro gets here I decided to mess with ram. On my Ivybridge setup, I could only 1800Mhz, with this I can get 1866mhz! not bad

soz, i don't know much about your prior posts, so if the reason has been covered previously let me know:

is there a reason why you're not pushing above 1.20v with a Swiftech H220?
post #6576 of 19540
Please update me, I went for 4.5 ghz overclock over 4.4:

Username: jrcbandit
CPU Model: 4770K
Core Multiplier: 45x
CPU VID: 1.36 V
Input Voltage: 2.00 V
Uncore Multiplier: 36x
Uncore Voltage: 1.18 V
Cooling Solution: custom loop
Stability Test: Realbench for 2 hours, X264 for 15 passes
Batch Number: same as what I listed
Ram Speed: 2133, 1.57V, 9 11 10 28
Other: +0.135 SA, CPU Analog/Digital IO



I ended up increasing the voltage from 1.355 to 1.36 to get x264 to work for 15 passes.



As you can see, I got a very poor overclocker considering I need 1.36 V compared to people running 45x multiplier at 1.2 V.... I do have the Intel overclocking warranty in case this voltage is not good in the long term.

You need 1.2vcore for 4.0? I'm at like 1.05

while other ocn users don't agree with LinX / IBT being a useful stress test. I still take it in as max temps and hitting about 89c/90c with with both apps. While my Ivy Bridge CPU delidded hit 80c w/ 1.5v on the same watercooling.

Once liquidPro gets here from ForzenCPU. Pop off the IHS apply the liquid and up this overclock.

Yeah... even if all settings are at stock, voltage at auto or normal (aka stock voltages) 40x core needs about 1.18v to even boot, I just 1.2v to be bit more stable.

Ok - throw up the benches, above 200gflops? I got 208 at 4ghz, though i didn't try to bench much, that was just one run w/ 6144mb RAM - though still, you need 1.2vcore? 1.05 gave me some hitches with p28.1/200gflops, but ~1.07-1.1 worked fine for hours of both

Ouch, if that's true it's the worst or one of the worst chips that i've heard of. I booted 4.0 and browsed for a while on 1.0v no problem and my chip is ~average

Try OCCT Large instead of LinX / IBT, let me know what temps you get?

My old 4770k (graphed in the OP) required a very, very similar voltage to boot. what batch# have you got?
