3570k First Overclock Windows Crashing

[0xygen]

I'm running a 3570K on an ASRock Z77 Extreme4 at the moment with a Hyper 212. Currently I'm trying to run my PC at 4.4GHz and I've been experiencing crashes and I'm not sure it's due to an unstable OC or drivers. When my PC crashes there is no BSOD, it simply restarts, sometimes a loud buzzing noise will be produced by the speakers too. At first I assumed the PSU was the problem as I had a 3 year old Coolermaster 460W which I have replaced with a Corsair TX650.

I've tried various offsets and I'm in the process of trying it on fixed mode.
I'm pretty sure temps aren't the problem as I'm only hitting ~75C in prime.


These are the errors I'm getting in Event Viewer after a crash:

Here are my settings in case I'm overlooking anything: (offset is at +0.110V, peaks at 1.264V during prime)

First off, do this to disable auto-restart on a BSOD : http://pcsupport.about.com/od/windows7/ht/automatic-restart-windows-7.htm

Second, follow this OC'ing guide for the Asrock boards: http://www.overclock.net/t/1198504/...-sandy-bridge-ivy-bridge-asrock-edition/0_100

Good luck!

I did try disabling auto-restart by pressing F8 during Windows start but it didn't do anything, I'll try that.

That's also the guide I've been using.

Is my offset seem really high or does it differ a lot from chip to chip? I'm using +0.080V at the moment and it peaks at 1.232V during a prime test, averaging 1.208V.

From what I've read it's better to mess with the CPU offset rather than turbo too right?

I ran mine stock for about 4-5 days to see if it was stable, it was, so I ramped up to 4Ghz, and ran it there for about 3-4 days (about 50*-55°c), and it remained stable. Right now I have it running at 4.2Ghz stable (about 50-60°c depending on room temp). It did lock up Friday night, but thats when I connected remotely via LogMeIn, and not sure if it was just the software that screwed things up (it was actually extra cool at the time).

On my Gigabyte board, the only change I've made is to the mulitplier. Everything else was left to auto. CPU-Z is showing voltage at 1.151-1.156.
Rock solid at 100% with Rosetta@home and/or playing BF3/Farcry 3.
Running Hyper N520 cooler.

Try checking if it is your memory instead, change the memory frequency multiplier lower to maybe 1333 instead

The best way to eliminate the OC as a possible root-cause is to set everything back to stock and see if the problem goes away. If it does go away then you can look at the OC settings as being the problem and re-optimize your OC.

During my brief ownership of an Extreme4 and OCing with a 2500K, I couldn't get it stable with offset voltage. Once I switched to manual voltage, it was no problem to get 4.5 or 4.6.

 

[0xygen]

I managed to run prime for an hour with it on manual with a voltage of 1.25 so I assume it's offset mode causing the crashes. Testing different offsets now.

 

[tweakboy]

It can also be a bum chip from a bad stash.

I doubt its mobo, could be PSU as well. gl

I've gone back and forth with LLC on my Extreme4 and I'm currently favoring "LLC Off", aka "Level 5". I was having instability at 4300mhz with +5mv with LLC @ lvl3 which resulted in a 4-core full load voltage of 1.208v (as reported via CPU-Z) and a 1-core partial load voltage of 1.216v, and switching to LLC @ lvl5 (and leaving the offset at +5mv) brought my 4-core full load voltage down to 1.168v and my 1-core partial load voltage up to 1.216v and restored stability.

Other than turning off LLC, only thing I can suggest is giving it more volts. I've had no positive effects from using LLC on this board.

 

[0xygen]

I've now tried an offset of +0.1000V and dropped the multiplier to 42 yet I still crash using offset mode with LLC both on and off.

I can't understand as it will run fine at 4.4GHz with a manual voltage of 1.25V

Yeah, I was pretty frustrated with the Extreme 4's seeming inability to overclock with offset voltage. This, combined with the fact that both boards I got exhibited minor but audible coil whine, eventually resulted in me exchanging it for an Asus P8Z77-V Pro.

 

[Yuriman]

Well, I've been pretty happy with my Extreme4 thus far. Newer bioses have made it a reasonable overclocker, I've been able to hit 4.8 without silly voltage.

Try overclocking with Intel's utility, I've had great results.

I posted this in another thread but this is a slight modification of it.

I recommend you try the Intel Extreme Tuning Utility for your first overclock. You don't need to reboot when changing multipliers/voltages, and it works a LOT better than the software included by motherboard manufacturers.

First you need to go into bios and change vcore to offset mode, but don't change the voltage (I set mine to +.005v because +0v wasn't available). In power saving features, disable C3/C6 and Package C states, but make sure you leave C1E enabled. Basically everything else can be left at default.

Once in windows, load up the Intel utility and max out the Turbo Boost Power Max and Core Current Limit, like so:

This basically turns off TDP limitations (your chip is rated at 77w TDP but you want to be able to draw more power than that when overclocked).

To overclock, drag the multiplier sliders up and hit apply. Do not play with the reference clock, only multipliers. You'll probably want to go up 1x at a time and run Prime95 or IBT to test for errors. When you reach a threshold where you're no longer stable, you can either increase the voltage, or drop your multiplier back down.

The max safe voltage for day-to-day usage is arguably about 1.3v, which on my board is about +132mv. I can get up to around 4.6ghz on my chip without going over 1.3v but your mileage may vary.

I'll give this a go and see what happens.

Is increasing the current limit and turbo boost power max dangerous? I've left them on default at the moment.

I assume there is no way of saving the settings? Once I restart my CPU is back at stock until I open the utility again.

No, it just allows the CPU to draw as much power as it needs when OC'ing. As long as your vcore is not set to some crazy level (1.5v+), its OK. Many boards in the past did not have this power limiting feature, its only an unnecessary hindrance to OC'ers IMO.

 

[tweakboy]

If you overclock turn off C1E and speedstep.

Those crashes without bsod are clear sign its the CPU or voltage or mobo.. Possibly PSU but I doubt that.

Do you remember having to do anything special to use this? I seem to recall downloading it and trying to run it, but it bailing because it didn't like my chip or motherboard or something (AsRock Z77 X3 with a 3570k, not much different from you). I'll have to look into it again.

Still having problems, no matter how high I set the offset I still get random reboots.

Give up on offset - or get an Asus.

I have done this enough this week I recognize that your settings in the pictures are basically from the same guide I used, which also seem to jive with general recommendations from people here that I trust as knowledgeable. FWIW you are started off right.

Something about your voltage sounds strange though, at similar settings (+.004 turbo, -.005 offset, LLC3), from the spreadsheet I kept I got a Vcore of 1.280 according to CPUz. With LLC 2 I got 1.320. Your 1.264 mentioned with LL3 and slightly higher turbo and offset seem a lot lower than what I got (Also on an ASRock board). I don't know if there's anything to this to help you out or not.

When do you crash? During stress testing, gaming, when you walk away and come off of screen saver, when you surf?

You can be stable under stress testing for hours, but crash at idle or even just sometimes be unable to boot. And this could be Windows or RAM related and not O/C at all. As Idontcare mentioned, maybe set everything back to stock and run with that a while, see if the problems go away. That may narrow it down to a hardware issue, software issue, or directly related to the O/C settings. Especially at this point where nothing else seems to work.

 

[richierich1212]

Offset is worthless. Just stick with manual.

 

[0xygen]

The overclock is definitely the problem, I can run it on stock settings with no problems at all.

I think C1E state may be the cause of the problem. I disabled it and managed to get a couple of hours with no reboots. Didn't have long enough to know if it is the problem today but I'll test it out tomorrow.

I am running stock bios p2.00 and offsets and -.010 offset with PLL overvolt enabled.
I noticed that llc-3 didnt help much after after x44 or so.
I changed the llc to llc-2 and it helped I then turned c1e back on.
To reach 46-4800 I was forced to use llc-1.
Now the problem with the llc-1 is I cant lower the voltage at all.
To me 4600mhz at 1.256v seems to be the best choice for me.
It seems that most of the 3770k oc better then the 3570k but why I dont know.

 

[0xygen]

Managed to run for about 3 hours this morning using offset with LLC1 and C1E disabled then it rebooted.

Are there any power saving states I can enable whilst using a manual voltage to save power and extend CPU life rather than using the full voltage all of the time?

 

[Kenmitch]

What memory are you running? If two sticks which slots? Counting from the cpu two stick configuration is 2nd and 4th slot on every newer intel board I look up. This can cause issues with overclocking if your using the other two slots. Running four sticks can also cause issues with overclocking.

The loud buzzing freezing I've run into with my 2550k when trying for uber high overclocks

I've never had an issue using offset vcore other than the random bsods at idle but all it took was to disable c3/c6 in uEFI to cure it.
