How much core voltage is dangerous?

post #1 of 9
Thread Starter 
You heard it! As the tittle says. So how much vcore is dangerous? Like, dangerous so it won't last long or burn up my components! D=

I've got an Intel i7 4770k (bad luck at the lottery, can like overclock max 4.6 ghz with 1.4 vcore and 2.000 CPU input voltage?)

Corsair 850 RM Gold Modular 80+

Asus Z87-Plus (Motherboard)

From the Haswell Death/Degradation thread:


CPU: i7-4770k

DELIDED: YES

REPORTED CONDITION: DEAD, R.I.P., MUERTO, KAPUTT

CAUSE OF DEATH: EXCESSIVE VOLTAGE, 1.37-1.4+V VCORE

HOW LONG OVERCLOCKED: Approx one (1) year

OP DESCRIPTION: I had ran a daily overclock of 4.4, but that wasn't the problem. My voltages were off the charts. My vcore was set on adaptive instead of manual and it would range anywhere from 1.375 to 1.4+ My input voltage was 1.9 and my uncore voltage was somewhere up there. I don't remember. I had this chip delided and OC'd for almost a year.

THREAD: http://www.overclock.net/t/1475351/i-think-my-4770k-gave-out

WARNING: HardOCP.COM state that anything over 1.35V VCORE 24/7 will degrade an Haswell pretty fast when conjoined with heavy loads and lots of working hours every day.

Anything over 0V is dangerous and will kill your cpu given enough time. The important question is how long do you want it to last?

Ok, thanks! I'll use the Asus Turbo Feature! =D

If you want to be 100% sure that it will last that long I'd stick to 1.25V. However if you don't mind tweaking your oc from time to time 1.3-1.35V should be good since cpus usally just degrade meaning that they need more voltage over time instead of suddenly dying completely.

Edit: Forgot to mention that I wouldn't go over 1.2V without delidding.

Personally I keep vcore under 1.35, vrin under 2.0, vring under 1.3. IMO 1.25 is the sweet spot for vcore.

LOL ive been at 1.39v+ for two years, 1.42+ for more than a year, i think im at 1.45v to really push out the last juice of my 3 year old 2500k. but the CPU doesnt get past 67C on Prime 95 Blend.

I worry now that i read that post....

Oh well i guess ill just buy another 2500k if i need to rolleyes.gif
