I envy you. I need 1.25V set in bios for 4.3 and I'm not sure wen that's 100% stable.

You only changed the Vcore and Core multiplier keeping everything else at auto, or did you have to tweak some other settings as well?

It's the cache. I got it when I upped the cache ratio from 37x to 39x at default 1.05V.

New 4.7 Overclock for ya Wizzie.

BangBangPlay
CPU: i5 4670K
Core Multi: 47
Core Voltage: 1.285V
Uncore Multi: 42
Uncore Voltage: 1.200V
Cooler: H100i
Stability: OCCT 9 hours, IBT 20 runs Max
Batch: 313
Ram Speed: 1600 MHz XMP
Picture Verified: Yes

Larger Image

Unfortunately anything over 12000 will throttle in Linpack, so I went a few extra hours in OCCT (9 Hours Large Data) for stability. Linpack certainly isn't for any voltages close to 1.300V.

You input 1.285v to the BIOS but HW reads 1.312v. ;)

 

Your results have been charted.

So after a week of tweaking, I found out the OC potential of my 4770K and as like many, it's not too good. However, 4.3Ghz @ 1.168V does it for me 24/7, temp-wise and performance-wise. Batch no. is L311B203.

4.4Ghz isn't even stable at 1.216V and as the next VCore bump is 1.232V, I thought that 4.3Ghz @ 1.168V obviously scaled better and was good enough. Bench-wise, I could easily runs benches at 4.6Ghz @ 1.248V. 4.7Ghz on the other hand needed a little above 1.350V just for benches, stability was another game.

I guess coming down the line, this 4770K is the first chip that I couldn't do 5Ghz with. By that I mean the following in series:

When Sandy came out, max frequencies, 2500K @ 5.2Ghz (air)
Ivy's retail at release day 3570K @ 5.3Ghz (water)
Ivy 3770K @ 5.067Ghz (water)

And as for Haswell, I really didn't bother going above 4.7Ghz for obviously reasons. And yeah, Both Ivys and this Haswell have been delidded.

As for the memory, I was able to take my stock 2133Mhz Ripjaws Z (4 sticks) up to 2800Mhz @ 12-14-14-35 2c (1.675V). Just to mention that these aren't ordinary Ripjaws Z, but they rather came with Hynix CFR's in the production of 2012. I can easily bench at 12-14-12-35, haven't tried any lower. As it wouldn't boot at the next IMC multiplier i.e. 2933Mhz, may it be 1.78V or 15-15-15-45 clock speeds, so I knew that this was CPU bound. The max I could get was 2832Mhz and that's about it.

As for straps, the 125Mhz was the only one that I could boot on, 167Mhz or any other combination didn't work no matter what I tried.

Yeah, so every result charted reflects that reading? How about your OC? Which value do you use? I don't trust software that was created before the hardware that it is reading. AI suite gives me yet another reading and that software comes with the MB. So 1/8th of your results reflect HWMonitors reading and the rest are what everyone entered into their BIOS? Nice...

You can use HWinfo, which has an update a few days ago, but it gives similar results to HWmonitor. I'm a bit more strict on picture verification but if you don't think the voltage is accurate, what is?

There can be discrepancies, after setting a vcore in bios when you get into windows LLC can have an effect on it with vrise or vdroop, even then the voltage set or read in software is rarely the same as the actual measured voltage.

Reporting the voltage set in bios isn't a bad thing, with the voltage in software also being visible. The more info the merrier!

I am not trying to be a jerk or a complainer I just not sure that Vcore value is totally accurate. I will update HWMonitor, but I always focus on what I input into BIOS because that is the value we all control. Maybe the FIVR takes more voltage than we allow it, or maybe HWMonitor is reading or displaying the wrong value. It wouldn't be the first time HWMonitor has done it, and it's accuracy varies depending on your MB. Until we know for sure I would just keep it set the the value that everyone enters in their BIOS, or the value displayed by CPUz because that is surely what the vast majority of people have been reporting. I know this isn't a contest, but it is supposed to help people to see what values other's are using, how they are stressing, and maybe how they perform compared to others. I suppose it could also indicate better batches, but I personally feel it is totally random.

I think the results should all represent the same value, and I also think more emphasis should be placed on stability than how low people can get their voltage. Other users should be encouraged to post their screenshots, I think this only will discourage some who reported their BIOS entry and not the HW Vcore value. I place much more value on the (stable) results I have seen pictures of then the supposed results of the people who just post their numbers. Just a thought, it is your thread and your results so no worries either way man...
