Why isnt 4.6ghz working?

So I recently started overclocking my setup after fixing issues with my cooler. Everything was going well until I hit 4.6Ghz. 4.5Ghz was perfectly stable after p95 test with an offset voltage of 0.005 and a Turbo Voltage of 0.008. However whenever I set it to 4.6ghz, no matter how much voltage I increase it to, the PC just BSOD's at start.

I've also tried using fixed voltage @ 1.125, 1.130 and even 1.135v and it still wont boot into 4.6ghz.

Any thoughts?

Thank you for your help.

I would keep upping the voltage until it boots. Also you need to make sure it is not overheating.

I'm using an H100i and I've tested those voltages at 4.5 ghz to make sure it's not overheating. Temps around 65C in p95.

Could be me but those voltages seem rather on the low side?

Really? 4.5 ghz works fine on 1.2v no p95 errors. Why does 100mhz make such a difference?

Even then you're reaaaaally lucky :P

I need 1.33V to get 4.4 stable...

OK thanks guys, what's the max voltage you'd recommend given my cooler and temps?

Most say 1.4-1.45

I personally like to keep it under 1.4

Just tried 1.4v, still bsod at startup :(

OK, I'm now having trouble at all speeds with the voltage fixed at 1.4v. The only stable settings are the ones I had previously -

Turbo Voltage - +0.008v

Offset Voltage - +0.005v

Core speed 4.5ghz

Why am I having trouble with the fixed voltage mode? By my calculations the max voltage above is 1.113? Or am I being dumb?

Ty all :)

Maybe there is a faulty on the processor.. 1.4v should be enough to 4.6ghz...

Any other ideas guys?

Have you tried enabling the PLL overvolt? I thought the multipliers on some SB cpus hit a wall sooner than others.

Please correct me if I am wrong.

Lower your PLL voltage to about 1.55v. Also try using a fixed voltage at about 1.3v. You have a decent chip, 4.5ghz@1.2v is great. Just keep playing with it.

I've read a little about PLL voltage. Why does lowering it help the OC? Thanks for the advice :)

4.6 at those low voltages i wouldnt recommend. yours seem even better than mine if its stable at 4.5 @ 1.19 (this is mine) but run it at 1.2v just to be sure. for 4.6ghz i would suppose try uping the vcore to 1.22v entirely.

glad to see someone else with a great chip. you should post a cpu-z of it on overclock.net :P

try suicide running it up and see how far it can be boot stable. (mine maxs out at 5.1ghz before it becomes volt limited @ 1.45v cant go to 5.2 without seriously cranking up the voltage.)

also i would read up on the ivy bridge guide on Overclock.net as well. itll give you good insight of what each of the voltages do and how they affect things.

BTW what is you CPU's Batch Number. we might have a simular batch.

i5-3570k @ 4.5ghz at 1.2v (5ghz @ 1.4v max stable) , Radeon HD 7850 @ 1200/1450 Clocks http://www.techpowerup.com/gpuz/kasmr/, AsRock Z75 Pro3 Mobo, 8gb of 1333mhz ram @ 1600-8-9-8-16.

actually been consulting this guide Here - http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition

If I can find the batch number without removing the cooler then I would be happy to post it :)

What error code are you getting in the bsod? Make sure it's the error code that means it needs more voltage, and not some other error

Batch number will be on the actual Box too ^^ unless you threw it out...

I'm running windows 8 so the BSOD is as useful as nothing. Just an unhappy smilie and 'Your Pc has run into a problem'.... Well no shit..
