I am cooling it with a Noctua NH-D14 triple fan.
I still haven't tested all that much, but so far temps seem to be in check.

To go for 4.7, I think my chip will require more than 1.3v.

This is my cooling setup:

Looks pretty good to me, you might even be able to squeeze 4.7 if youre lucky and you fancy it. smile.gif

When I get more time, I might try that.
I am still waiting on my new monitor.

Also, I am still at fixed voltage with C-states disabled.
I will try to fine tune the bios settings and VRM settings and then try offset voltage.

My previous 2500k needed 1.4 to be rock solid at 4.8 and a bit more and I could use it at 5.0 stable.
Temps were in check with this same setup, but from what read, Sandy Bridge with the 32nm fab and the solderes heatspreader is cooler.

Cheers!

Sandy bridge was on a larger node, having a larger die and less transistors, but also soldered as you say, so that combined made it easier to cool overall. I dont think the voltages are comparable across architectures like that, but I'm certainly not qualified to tell you exactly why tongue.gif

I used mine with all the C-states enabled and with offset. It takes a bit more time to do but I think its worth it. Some people dont though, and I think its fine to stick with manual voltage too if you cant be bothered. GL smile.gif

It's been 3 years now since owning my 3770K + P8Z77-V Pro + Crucial Ballistix Elite 2133 CL9.
Still going very strong with a delid and a voltage many people told me was suicidal and would degrade the CPU badly. No signs of any degradation at all. Still rock solid, zero crashes, no WHEA errors, can run any stress test for 24 hours straight.

Running a delid with Liquid Ultra between both the die-IHS and IHS-block. Blocks a swiftech H320 with an additional 240 rad from a H220 kit and push-pull Noiseblocker XL-P fans. Set to a pretty conservative PWM profile. (Max speed for fans and pump is 60% when under 80c).

I also run 4.8 @ 1.384v or 4.6 @ 1.296v depending on the ambients when they get really high here in the summer. I could run these clocks but it will run mid 70's in games and that's a tad high maybe but yeah. With these settings and normal 22c ambients it runs mid to high 60's in games.

Was playing some battlefield today.
Hottest cores went to 65-67 degrees during gameplay.
Vcore at 1.297.
Are these Temps okay?

Cheers

About the same as i'm getting with 4.95 1.448v in BF1, GTA V and other demanding titles. Usually 65-68c hottest core. Fans and pump don't really spin up at those temps so.

Guess that is the delid difference. smile.gif
I am getting these Temps at 1.297v with a NH-D14 in Lisbon. It's a hot day of high 20s today.

Just created account to post my thanks to Swag, Totally Dubbed and others for making such an awesome guide.
This was my first time successfully overclocking my Ivy Bridge CPU.
I ended up changing some settings that where in the guide but that part of the overclock journey. smile.gif

My rig:
MB: P8Z77-V LE PLUS
CPU: Core i5 3750k
Cooler: Hyper 212 EVO
RAM: Corsair 16GB DDR3 1600MHz
PSU: Corsair CX600M PSU
No GPU at the moment - thinking of buying RX 580, doing research atm.

Following the guide I managed to get Prime85 8h stable OC of my i5 3750k @4.5GHz on 1.25Volts. Great!
I did the offset math and switched to offset mode. But my system didn't like it and started BSOD like a madman. I didn't understand what was going on.

I checked my offset math:
Formula: (MANUAL vcore) MINUS (VID on 100% load) = offset value
My manual vcore was 1.25Volts
VID was fluctuating between 1.2159V and 1.2209V. 1.2209V was most frequent.
So 1.25 - 1.2209 = 0,0291 that makes it 0.030 for offset right?
Or 1.25 - 1.2159 = 0,0341 that is 0,035 for offset volts

With 0.030V I got BSOD before I could reach desktop and 0.035V I only had time to run Bluescreen viewer before BSODed again. Info from bug check files revealed not enough volts so I started adding notch by notch. About 0.045 offset mark I could run Cinebench. CPU-Z showed ~1.2V peak while running Cinebench. That meat that my CPU was craving for more power. As I up volts notch by notch BSOD went away and my 3750k was 6h stable with Prime95 at 0.080V offset. That's a lot right? However WHEA errors still persisted and offset value was uncomfortably high already.

Turning point was when I discovered running AIDA64 or Prime95 for about 10min and then ran Cinebench my CPU got massive drop on volts - that's Vdroop? When my CPU drop below 1,24V that's when Windows registered WHEA error. To counter balance that I up the LLC to extreme setting and then could lower my offset volts to 0.60V. I ran Prime95, AIDA64, Cinebench, IntelBurn Test all came out clean and my system is fast with no BSOD or WHEA errors. With extreme LLC and 0.060 offset my peak volts are somewhere 1.264 which are considered safe.

I had lots of help reading this thread and I hope my journey will help someone else. (If someone else is late for the Ivy OC party)

I really couldn't have done it without this guide.
So thank you again!

Hi All, newbie here with some questions using offset mode for overclocking.

Clocked i5 3570k @ 4.4GHz. Ran Prime95 for 12 hours and achieved stability with a manual Vcore of 1.280V.

At load I am seeing VID bounce between 1.256-1.261V. With LLC set to high (50%) my Vcore is 1.280V at idle and 1.256-1.264V when at full load.

I would like to lower my voltage at idle so I'm assuming that's where offset mode comes into play but I'm not too confident how to set it up. Any suggestions? Thanks

Intel i5 3570K
Asus P8Z77-M Pro
