Worst i5 3570k ever.

[killcomic]

I am currently running an i5 3570k at 4.2Ghz on an Asus P8Z77-VL-X. I'm stable with the Vcore at 1.225 volts with a max load temp of 70c. My LLC is set to high (50%).

 

I pushed my Vcore to 1.3 and increased the multiplier to 4.5Ghz and died immediately with Prime95. I dropped to 4.4ghz and it lasted longer but died an ugly death regardless.

I moved the LLC to 'very high' (about 75%) and no more BSOD, but WHEA errors started to pop up. I pushed the Vcore 1.32 and the immediate WHEA errors stopped. After a day of use, I checked the even viewer and a single WHEA error, caused by the CPU, was sitting there. The load temp with Prime95 was about 82c.

 

I really don't feel comfortable taking the voltage higher or taking the LLC to Extreme (100%... it really overshoots by lots then...). I could also try to enable PLL overvolt, but I know very little about it and there is a lot of contradicting info on the internet.

 

Question is, could I push further safely (or as safe overclocking gets) or should I just accept that I got a rubbish 3570k and be happy with my 4.2Ghz?

looks to me like the silicon lottery just shit on your cpu.

[eX.Drunk]

Well, that's plain badluck. My i5 3570k can go up to 4.7Ghz.

And 4.2 is pretty good too mate! Stick with it.

What cooler are you using?

^ . That is why I tell people to just get Haswell. Ivy could be just as bad at times and required a good MB. 

 

If it makes you feel better op? My friend has a ROG board and a 4770k and dual rad water and is at 4.2 at 1.3v. Least you didn't spend that kind of cash lol. Even worse? He bought it for Flight Simulator where you need a massive OC. He is very sad.

Go ahead and set your LLC to extreme and set your voltage at 1.25.

 

Drop multi to 40.

 

Then see if your voltage under load is 1.25 or if it goes above that. If it does go above that then factor that in when setting your voltage.

 

Set 1.25 get 1.30 etc.

 

Then start adjusting your multi from 42 on up.

Noctua nh-d14

I tried 1.3v with Extreme LLC to see what happened and under load it would hit 1.35v. Since I started overcloking with a P4 2.4Ghz back in the day, LLC still makes me uneasy.

Ok. Now, set your voltage to 1.225. Set LLC to extreme. You should get a voltage of 1.275. Set to 4.2 and see if it is stable.

 

I vary my LLC from Very high to Extreme depending on my OC. My 24/7 OC of 4.9 Ghz is ran with very high LLC at a rock steady voltage. When I go north of about 5.1Ghz I go to extreme to ensure I get no voltage drops(1.5 volts with Very High LLC will drop to 1.488 under load).

 

Some boards are different in how LLC settings work.

There seems to be a 0.05v overshoot in voltage with Extreme. Event that didn't help. It appears that I need over 1.35v to have a stable OC at 4.4Ghz. Perhaps too much work for too little gain.

Well. I would go through your bios and double check everything. Ram speed and timing, BLK is set to 100. Turbo mode is off. CPU power phase & power duty is very high, CPU current capability set to 130%, etc.

 

Very little set to auto may allow you to go further then you think. Or it turns to be alot of work for nothing and your 3570K doesn't like to OC.

[Thunderjolt]

My 4670k can get 4.2 Ghz with 1.3 volts

[killcomic]

My 4670k can get 4.2 Ghz with 1.3 volts

If it makes you feel any better, that's the equivalent of my CPU running at 4.6Ghz!

[DeathSentinels]

1.3V seems a little high for 4.5ghz. I'm able to get about 4.8-5ghz @ 1.33-1.35v (on a 3770k however)
and reach on full load with prime95 around 90c, on normal use around 70C. I'm using a H100I

with a MSI Z77 M-Power big bang which is a great overclock board.

[ZmanFTW]

I got my i7-3770K to 4.8GHz Prime stable. But Prime and other CPU stress tests are ultimately unnecessary unless you are planning on trying to break OC world records. I reached 5.0GHz gaming stable (not Prime stable). 5.2GHz had issues. That was with a TT WATER 2.0 Pro and Phobya PWM fans. If you want to do a "CPU burn-in" that makes sense run 3DMark, Unigine Heaven, or any other benchmarks that combine CPU and just get your system nice and hot while overclocked and benchmarking/gaming. Shut down and give PC plenty of time to cool allowing thermal paste to harden up.

 

Gaming performance is what really matters to me in the end. Ivy and Haswell has made CPU overclocking less exciting and GPU overclocking more exciting.

Do you guys think my overclock is legit? OC to 4.2Ghz @ 1.040v?

ouch. you lost the silicone lottery big time.   if i had a chip that bad i would be temped to sell it and buy a different 3570k

maybe if you posted a screenshot of it under load.

Nope it's alright, now I'm at 4.6ghz@1.116V primestable for half an hour now

this sounds too good! 5ghz should be easy as long as your temps are still ok.

Here is a screenshot after a reinstall of w7. Voltage has gone up a little without me changing anything.

I thought about it but I could either get stuck with a worse chip or, if I had a better chip, the 10% increase I could realistically expect would make no difference by the time my chip is not good enough for gaming.

Dang! Yup, I do feel a bit better for myself but I can't help feeling a bit bad for him.

True. It should be ok for gaming i love overclocking and benchmarks so i couldn't have that cpu. It shouldn't slow you down much unless you get another gpu anyway.

Yeah, I'm running 2xHD6950's in crossfire. Considering that I got 2 kids and a mortgage, I doubt that I will see a GPU upgrade in the future.

Sure, I am thinking of selling my 3570K which is able to do 4.4GHz at 1.1V.

Super legit
