Looking for people with 4770k OC experience

Hey people!

So, I'm basically trying to milk the most performance out of my old 4770k (For CEMU emulation). Ran it at 4.5Ghz for the longest time, but getting it stable at 4.6Ghz has been a struggle and I'm trying to figure out if I'm crazy.

At the moment, I'm stable enough at 4.6ghz to run Cinebench R20 (scored 2136/436 this any good?), but voltages/temps are higher than I want them to be.

I've attached a few images with my current settings, and the biggest bother is that I need the Vcore set to 1.40V in bios to get some stability (goes to 1.416V while loaded). Temps peak out at 87C while running Cinebench R20 and I really don't want to know what Prime 95 would do to them. Note that these temps are with a H105 AIO, and a delid using MasterGel Maker thermal paste.

I just want an experienced hand to tell me if I just have a bad batch or something? Am I missing some settings that might improve the stability so maybe I can shoot for 4.7Ghz without setting fire to it?

Specs that may matter:

Z97-HD3 Mobo
16GB Gskill 2400Mhz set to 10-12-11-29
Corsair H105 AOI
RTX 2060

Thanks!

Settings that matter?

Vcore = 1.400V
Core ratio = 46x
VRing = 1.354V
Cache Ratio = 44x
SA = +.25V
CPU IO Analog = +.25V
CPU IO Digital = +.25V

You're right at about the clock and temperature ceiling of the 4770k where you will need to delid to progress any further for that extra 100-200 MHz. Pre-delid, my 4770K couldn't run anymore than 4.3GHz @ 1.15v otherwise my H220 AIO (240mm) wasn't able to cool it any further (extract more heat). Post delid, I was able to go up to 4.5GHz at 1.27v for 24/7 and 4.6GHz at 1.336v for some gaming and benches, while keeping temperatures below 85C.

I do know that as soon as I did the delid, I was able to get some stability at 4.6Ghz when it was impossible before. Mind you I'm not using a liquid metal thermal paste at the moment on the die so I wonder if that will make an improvement.

Even then, you said you could do 4.6GHz at 1.336V, where as I was only able to do benches at my current 1.416V . . . Is it because of the temps being too high?

To your first point, I settled on using Coolaboratory Liquid Metal Ultra (CLU) because it prevented the pump-out effect, which is common to many non-metallic paste when used on the die. Secondly, the heat transfer coefficient of CLU is multiple times better also (80 vs 30), which is crucial for removing heat faster from a small CPU die.

The difference between 1.336v and 1.416v is within silicon lottery tolerances, but the potential of CLU or a liquid metal to reduce your voltage is good. There is a phenomena where higher heat intensity does require more voltage to sustain signal integrity. It's probably not much, may be a few 10s of miliVolts. If you try it, take care so the liquid metal does not get onto other circuitry on the motherboard or the CPU PCB.

My uncore/cache was kept at 43x and voltage at 1.25v. Because Core was and is still king, keeping uncore low allows core to be stabilized at higher clocks. The 4770K really does not overclock further than 4.6/4.7GHz. It wasn't until the 4790K, when 4.9/5.0 became more accessible.

AIO's are best at idle and mid, but i've never been able to push them too hard. True liquid or phase ftw.

Hillbilly method - Noctua D15 + silver paste running upright with case on its side + a third fan on heatsink; Gravity sucks, but heat rises - & prefers heatpipes. The sheer weight of the HSF also compresses the paste some, which enables ideal contact

See my sig build https://www.overclock.net/forum/1808...heat-wave.html

I had 4.6GHz stable for a period but as the months went by I started getting lock-ups/BSODs and decided to keep 4.5Ghz.

There is a lot of good info - index on first post. You may have a better chip then me since I had delided mine.

Good luck!

Thanks for all the info guys!

So its good to know that the voltage I need is just within silicon lottery ranges, I figured as such (Why can't I get a good one -_- lol)

Either way, I don't plan on changing the cooling solution or anything, I'm just trying to get a little more single core performance so that I get better frame rates in the CEMU emulator. You'd be surprised that running 4.6Ghz over 4.5Ghz actually sees about a 5fps improvement, so I'd like another 5 from 4.7Ghz lol.

I've ordered some Coollaberatory liquid metal ultra and I'm going to put that between the core and IHS, of course being very careful to apply it correctly. Hopefully this will decrease my temps a little which may in turn require less Vcore. Because as far as I can tell, most people with 1.35+ Vcore and delids get temps closer to 75-80C, and I assume that my lack of use of liquid metal is the reason why I'm getting higher temps.

Depending on how the overclocking scene develops for the Ryzen 3000's I may end up upgrading in the near future, since my CPU is around 7 years old. So far the Ryzen 3000's don't have many successful overclocking reviews, seeming to be limited to their boost clocks at best, I'm hoping that people find the right recipe to get some real OC gains from them. But honestly my 4770k has been a great CPU, and I've run it at 4.5Ghz since I bought it, but its performance is starting to fall quite a way behind.

Don't forget to tingle Input Voltage, keep it above 1.80V, below 2.1V and remember that setting it too high will cause instability.

Oh? too high also causes instability?? I didn't know that. I think its set to 1.90V right now, I'll fiddle with it when I get my liquid metal paste.

Also on a random note.... I recently re-pasted the Core/IHS, thinking maybe the paste dried up too much (Didn't help). But I noticed that in the center of the core there are 3 scuffs, maybe 2mm long each and .5mm apart and I assume just surface depth. They are also on the IHS... I'm just wondering if that's going to cause a s*** storm when I use liquid metal? As it is, nothing seems to be wrong, but I'm using non-conductive thermal paste at the moment. (Sorry forgot to take a picture).
