3570K @ 4.6GHz very high voltage... Very bad chip or bad BIOS setting?

post #1 of 25
Thread Starter 
Hi,
Doing my very first overclocking with my I5-3570K, I always need very high voltage to be stable:
For 4.5GHz, I need 1.340V and for 4.6GHz, 1.415V. It is way higher than anything I saw on this forum or other overclockers's forums. So I'm wondering what is wrong? My chip or my BIOS settings??
Here are a few screenshot of my BIOS:

Any help is more than welcome.

Be careful going too far over 1.3 volts for the 3570k, in fact i would never go to 1.4 volts with a 3570k, i know of three people frying their chip at that voltage. So be careful.

Personally from the extensive research i've done and from hours of my own experience... going over 4.4ghz with a 3570k takes a lot of time to find that sweet spot unless you got a Golden Chip or Water Cooling but its very possible on air (to get 4.6ghz. In fact tonight i am going back to 4.6ghz, i was there before but i found a tad instability at that clock on my 3570k. I use a EVO 212+ CPU Cooler with push/pull air < push/pull means two fans on the cpu heatsink..one fan sucking in the cool air into the heatsink and back fan sucking the hot air out to the PC case back fan. It helps a little bit with keeping the CPU cooler than rather only having one 120mm cpu fan.

I wish i could help you more but simply cannot because i have a Asrock Z77 Extreme 4 motherboard and it's simply too hard to try and give you advice when you have a completely different mobo. Each mobo from various manufacturers all have their own niche to get a solid OC. My best advice is to google this..as in my case i googled "asrock z77 Extreme 4 3570K overclock" and i guarantee you will find many other threads from various forums from the google results of searching exactly what i did above and i suggest you find threads that have your exact mobo and cpu for overclocking. This is what i did and i found around 10 excellent threads via google that are specfically related to my exact mobo and cpu overclocking.

I did notice from your pictures though that you do not have a few things disabled that i noticed which should be no matter what mobo brand you have. You should have this configured below...granted your mobo does not exactly say exact what my mobo says for the options below but i noticed you had some of these enabled which should be disabled.

This is what i have below...

Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Disabled (always keep disabled)
CPU C6 State Support: Disabled (always keep disabled)
Package C State Support: Disabled (always keep disabled)

Internal PLL Overvoltage: Disabled (I find this crucial to disabled for OC)
Speed Spectrum: Disabled (can be turned on or off)
Speed Step: Disabled (can be turned on or off but i turn back on after i find sweet OC spot)

I wont go any further than this because you have an entirely different mobo than I but i am sure more computer savvy guys in here with great experience can help you further. I personally have a decent amount of knowledge in OC'n but i tend to refrain from helping others that do not have the same or close to the same hardware as i do...to me its like comparing apples and oranges because of how drastically different mobo's have an affect on overclocking the same cpu you and i may have.

Thanks for this answer.
I'll run some tests with the settings you recommend. However, for the Internal PLL Overvoltage, I have to leave it enabled. Passed 4.5GHz, the system will not boot if this feature is disabled.

That voltage is high for that oc. I would think for your oc it should be under 1.3. My 3770k is @4.6GHz 1.28v 1.8 PLL. On ivy once you get over 4.4ghz you gotta crank the PLL voltage up.

Just to correct some information:
CPU PLL does not have be raised over 4.4, I have 1.7 and I am at 5.0.

1.4 is safe for Ivy Bridge provided your temps are under control. There are people who have been running 1.5v for months without any issues. It may degrade your chip a little faster but no one knows for sure yet.

Internal PLL Overvoltage is perfectly safe to Enable, but you won't need it for mild overclocks.

There is no reason to disable Speedstep during or after finding your overclock.

Basically find the overclocking thread for your motherboard and go by the guide. It is not that hard.

That's my point!

So what should I do? Set the vcore back to 1.3 and try to get something stable just by raising the PLL?
