Hi all, firstly, many thanks for any help/advice guidance given. Its greatly appreciated.

I'm new to Intel, and very new to OC'in Intels, have had AMD's in the past due to cost. I'm looking for clarification on my settings, perhaps I should drop something down, raise something up etc etc. I'm a gamer through and through, so looking for good speeds for CPU intensive games, but where its not running red hot, or will potentially damage the chip.

Idle temp 28-32 Although CPUz shows CPU cloak raising and lowering a fair bit but no activity

Under load temp 74-77

My PC Specs:

MOBO: Asus Z87 ROG Extreme VI Maximus Formula
CPU: 4770k
RAM: 16 Gig (4x4Ghz Dimms) Corsair 2133 MHZ Quad/Dual Channel Ram.
CPU Cooler: H100i (With Arctic Silver Paste) with 2 x Corsair SP120 in Push (Pushing through top of below case)
Case: Corsair Carbide 540 - 3 x Corsair AF120 Performance Series, Low noise in front sucking air in and 1 x AF140 Quite Series Low noise at back pushing out
GPU: EVGA GTX 770 (Soon to be a GTX 780ti :D)
PSU: Corsair HX850 PSU

My Current OC Values:

XMP 11-11-11-27-2N-1.5
CPU Strap - Auto
PLL Strap - Auto
PLL Selection - Auto
Filter PLL - Auto
BCLK Frequency - 100
Sync All Cores - 44
Min and Max Cache Ration - 42
DRAM Frequency - 2133 MHz
Extreme Tweeking - Disabled
CPU Level Up - Auto
DPI? Power Saving Mode - Disabled
CPU Load Line Calibration - Level 8 (Highest)
CPU Core Volts - Set 1.25 - Mobo/GPUz Reading Shows as 1.264
CPU Cache Voltage 1.2 - Mobo Reading Shows as 1.22
CPU System Agent - 1.15 - Mobo Reading Shows as 1.16
CPU Analog I/O and CPU Digital I/O Voltage 1.15 - Mobo Reading Shows as 1.16
SVID Control - Disabled
Initial CPU Input Voltage - 1.9
DRAM Voltage - 1.5 - Mobo Reading Shows as 1.52
CPU Spread Spectrum - Auto

Tests I've completed:

3d Mark for stability testing, all passed fine, with better scores, however on Firestrike with 377.80 drivers, it would sometimes crash. Rolling back to the previous version (beta) all is fine.

Aida64 System Stability Test: Max temps are 74 - 77. I've noticed although it passes the "test" that once or twice, be it at the start, middle or end of the run the CPU cloak and north bridge cloak drop from 4400 and 4200 to 0 and instantly back up again.

If you guys/gals have any questions, please feel free to ask, and again, greatly appreciate any help/advice given.

What programs did you use to load the CPU? Tried Handbrake?, convert a DVD to MP4 and check temps whilst its chewing at that. Was that FPU stress only in Aida64?
 
Well FPU testing sucks, high temps but didn't fail.

Temps were high high 80's to low 90's.

Are my voltages etc etc ok, could I change anything?
 
What will you be using the system for?

Edit- Read your post through, imo, i wouldn't bother with the IBT's, Primes etc, just use the system, if your a gamer, game, check temps, i've found that you can run all the benchmarks and stress tests you want, pass and think the system is totally stable, but fire up a game and it'll crash within minutes.

What i do is, Dial in overclock, if it boots great, then use a game like BF3-4 or Crysis 3, while playing, record the gameplay using something like Afterburner etc, record for around 15-20mins, after that continue playing for an hour.

When your done, use Handbrake to encode the footage to MP4 or something like that, check temps, if it passes all that then great.

That's exactly what i've done with my system (4.6 @1.26) and not had a single issue yet.

This man speaks the truth. I do however do a quick OCCT test with linpack for 30 mins. Then I game my ass off and stream at the same time. Then do a quick encode of my awesome gameplay.

For me, stability is the machine being able to stay on 24/7 and do everything I want without it crashing.
