4930K First Time Overclocker 4.7Ghz Am I doing this right?

[Son_of_Altair]

Hi Forum

Just recently built my first desktop PC and experiencing my first time overclocking.
My setup is:
Intel i7 4930K
Asus Rampage IV Black Edition
2x 8GB Corsair Dominator Platinum 2400MHz 10-12-12-31 1.65V
Corsair H110 for CPU cooling

I've been playing around with the bios overclocking tools and AI SUITE 3 using AIDA64 for stress testing.
My first stable run was at 4.7Ghz with multiplier of 47 on all cores and a CPU VCORE of 1.385V resulting in a core voltage of 1.420V for AI SUITE 3 and 1.408V for CPU-Z. Memory is in XMP mode and running at 2400MHz. A CPU VCORE of 1.380V resulted in an unstable system in 30 mins. Running AIDA64 I maintained a stable system for around 7 hours with CPU temps between 40-50 degrees Celsius and my individual core temps between 70-80 degrees Celsius.

The questions I pose are:
1. Is this a good oc?
2. Is the voltage too high and should I go for a lower multiplier and CPU VCORE?
3. What would the life expectancy of this chip be at these settings?
4. Should CPU VCORE always be at 1.408V even when not under load and if so is there anyway to drop the voltage in idle use?

Any responses will be appreciated and helpful
Thanks

CPU Ratio went back to auto after switching to xmp. will change the ratio back to 45 right ?

Yes and make sure the cpu vcore voltage is at 1.37v.

Is she stable with aida for 3 minutes?

[Ronario]

BSOD after 1:30 mins

[Nate152]

OK raise the vccsa volatage to 1.15v and test, if it still BSOD's try vccsa to 1.20v and test again.

How does she go now?

[Ronario]

1.15v BSOD after Windows started, 1.20v BSOD after 1min AIDA Stresstest

[Nate152]

OK let vccsa to 1.20v and raise the cpu vcore voltage to 1.39v and test again. Post your temps please.

[Ronario]

Worked ! Temps between 70c and 77c

[Nate152]

Ok this is excellent. Now You can open up your cpu temp monitoring program and play battlefield 4 for 10 - 15 minutes then check the maximum temp. Please post your temps after playing battlefield 4.

[Ronario]

Worked Fine too ! Max. Temp between 55c an 60c 🙂 This is awesome !

[Nate152]

Great ! You're temps are very good. The vccsa voltage at 1.20v is probably more than you need. I had you set it to that to rule out the ram causing the instability. You can try vccsa to 1.15v and if it passes keep lowering it until you find instability then put it back to where you were stable. Lowering the vccsa voltage will lower cpu temps a bit too.

For long term gaming sessions 70c - 75c is about the maximum you want to see.
