4770K - The CPU that just keeps on giving!

FlakGunna · 23 Jan 2018 at 16:55

Updated BIOS and managed to OC.

my 4670k is stable at 4.3GHZ 1.22v. 4.4ghz 1.22v causes BSOD after stressing. 4.6GHz didn't boot, BSOD straight away.

Could I up the voltage more? 1.22v seems a tad low. But then 4.4GHz it was reaching 90c on stress test. 4.3ghz was around 88c.

I had my 4790k at 1.31v at 4.7Ghz. and benched at 4.9Ghz at 1.38v.

Great stuff. What cooler are you running? Without delidding you would need a beefy cooler to keep Haswell cool at much above 1.25v. If the temps are running that high it would not be advisable to increase your voltages any more with the cooler you have. You might be able to lower Vcore a little if you have a mess about with some of the “advanced” voltages in that guide (when it’s back up) and get your temps down. Off the top of my head it advises setting LLC to high/extreme to stop voltage droop under load.

What stress test are you running? General advice seems to use Aida64 and NOT prime95 with Haswell as you may find it just heats it up unnecessarily.

That’s quite a nice chip - I think my 4770k is at 4.6 with 1.33v. But then I don’t know how the 4790s compare exactly.

I have that cooler.

I used IntelBurnTest. I heard it heats it up a lot like you mentioned so to not go by the temps that produces. I tried a few games and nothing is exceeding 65c @ 4.3GHz 1.22v.

Someone mentioned to use x264 stress test?

I do only have one fan attached to that cooler and so I will attach the other one, it's a huge cooler barely fits in my case so that should be fine.

What is LLC?

Yeah IBT I don’t think is a realistic measure of temps. Aida64 I have found a good test of stability and a much more realistic indicator of “normal” heavy CPU loads. 65 sounds peachy. Haven’t tried x264 myself but heard good things about it.

That is quite a chunk of cooler and shouldn’t have much trouble cooling it down. I’m guessing you mean one fan sandwiched in the middle? Adding the other may help you out.

Load line calibration - as far as my limited knowledge goes it is to do with the voltage being fed to the CPU - by default it drops under heavy load. Setting it to high/extreme will stop this and might increase stability. (Someone correct me if I’m wrong) on my Gigabyte board it’s under Performance - Voltage - Advanced power settings

Rofflay · 28 Jan 2018 at 16:40

Yeai set mine to extreme with umm pwm or something. It easy to google for numbers and try if it crashes in games NOT ibt its good. Dont run ibt run demanding games and stress test with firemark free on steam.

Btw mine at 4300 had for honor source games 1080p 240fps min fps i only really found dota2 to have a 200 barrier so far.

Had my 4790k @4.7ghz 1.257V (bios) for years. Recently had to drop it down to 4.5ghz as Planet Coaster kicked it's ass (resulted in 2 BSOD) I urge people to use games as stress testers instead of benching

That said, it's been rock stable @4.7ghz for years (Gigabyte Z97X-Gaming 7 motherboard)

I completely agree it always end up the same for me where an OC will pass some heavy 12 hour stress test but fail within an hour or 2 on a game. I do think stress testing for shorter amounts of time is fine to find out the rough estimate of volts needed.

Planet coaster for 30 minutes for CPU test and GTA V for 30 minutes for GPU test is quite a good measure

britain4 · 30 Jan 2018 at 20:26

True, GTA5 is about as demanding as it gets for GPU stability especially with some mods. Never played Planet Coaster but I love Theme Park-type games so I've just bought it and we'll see how my CPU clock fares.

Had this 3570k since 2012. The upgrade bug is getting to me now.

Indeed. I think it's at least worth waiting for the Ryzen refresh. I'd like a 12 core/ 24 thread Ryzen. I'd also be tempted by an 8 core/16 thread coffee lake - but the price would have to be right.

I really doubt that the mainstream ryzen platform will be getting more than 8 core/16 threads in the refresh. I think the refresh is for higher clocks and and fine tuning instead of core count increase.

Correct, each CCX is still limited to 4 cores. It won't be until Zen 2 (early 2019) that we'll start seeing 6 core CCXs and thus 12 core AM4 CPUs.

I'd still wait until early April if considering an upgrade though, since both Pinnacle Ridge and Intel's lower-end 300-series chipsets will be available (presumably).

Gimpymoo · 1 Oct 2019 at 23:41

Not far under 2 years since the original post and still going.

I fell like I should be upgrading but right now, I am still good.

I do not play as many "AAA" titles as I used to so that I imagine is really helping stretch this build out but honestly, 16GB RAM, R9 390, not played a game as of late where I have thought "Upgrade time".

Yes, there is a Noctua D15S in there with 2 x 140mm fans but this rig has never skipped a beat.

CaptainRAVE · 2 Oct 2019 at 08:06

Considering a 9700k currently. The 4770k does struggle on some more cpu intensive games, not many mind. Just need to justify the £700 I need to spend to complete the package.

Have the 8600k here and had no issues in any games. I'm expecting it to last me til next year at least, or until Intel come up with a high-core viable option

or you could just give in and join the dark side like the rest of us. Join us Jedi, join us and be free of the exploited colour blue.

Tried a 2600X sys last year and wasn't that impressed overall tbh compared to Intel, I'll give AMD a couple more gens.

Well I've taken the plunge. Goodbye i7 4770K, DDR3, overclock faffing, watercooling and my odd mix of SSDs/HDDs. Hello i7 9700k, DDR4, air cooling, pure SSD system.
