The "stock" setting to which I refer are the default settings provided by the UEFI BIOS after motherboard install.

 

The "stock" settings to which I refer concerning NickN are the ones the he suggests you perform before changing the values for the OC itself, they are as follows:

 

ANTI SURGE SUPPORT: DISABLED

HYPER THREADING: DISABLED

CPU C STATES: ENABLED

ENHANCED C1: DISABLED

CPU C3 REPORT: ENABLED

CPU C6 REPORT: DISABLED

C6 LATENCY: SHORT

CPU C7 REPORT: DISABLED

C7 LATENCY: LONG

PACKAGE C3 STATE REPORT: C3

DMI LINK ASPM CONTROL: DISABLED

PEG ASPM: DISABLED

CPU AUDIO DEVICE: DISABLED

PRIMARY DISPLAY: PCIE

IGPU MULTI-MONITOR: DISABLED

MEMORY REMAP: ENABLED

MEMORY SCRAMBLER: ENABLED  (may not appear in all systems)

AI OVERCLOCK TUNER: XMP  

CPU STRAP: 100

BCLK FREQUENCY: 100

LOAD LINE CALIBRATION: 8   

CPU POWER PHASE CONTROL: OPTIMIZED

ENHANCED INTEL SPEEDSTEP: DISABLED

TURBO MODE: ENABLED

SVID SUPPORT: ENABLED  ROG BOARDS ONLY

CPU SPREAD SPECTRUM: DISABLE

 

The base Asus BIOS setup list for manually clocking all systems is now complete. Please hit F-10 save and exit and then go back into your BIOS and RECONFIRM every setting posted above. It has been noted that some boards may not hold a setting. We want to confirm the above list has indeed been saved and the system is booting this list.

I am loving this ASUS MAXIMUS VI HERO board ... it was priced fairly well and it is performing well above expectations.  Plus it is a member of the family of boards that NickN recommends for OC'ing.

Thanks, Charles!

 

With my default speed BIOS profile, I haven't changed any the default settings, except disabling on board devices that I don't use. But I use the above settings for my OC profiles.

NGX - 28-29 fps

 

777 - 29-30 fps

 

Just wondering if you had your Frame rate locked to 30fps for these test.

The initial setting in Nick's guide is locked to 30 FPS.

Your FPS in so close to that I was wondering are you set to 30FPS?

 

If you are do the exact same again with FPS set to unlimited and let us know what you get.

Dave:

 

Yes, the limiter was set in NVidia to 30 fps ... but that was not what limited the result.  The frames were bouncing around from 27 to 30 ... I assume that if the actual frames were at 40 and the limit was set to 30 there would have been a steady reading of 30 in the Shift+ZZ reading within FSX ... agreed?

 

I just made the jump to 4.6GHz using NickN's guide ... it passed 10 runs with Intel Burn Test ... I'll push on with OCCT / AIDA64 and Prime95 throughout next week.  The week after that ... 4.7 ... and after that 4.8 ... which is where I expect I'll hit a wall ... all I really want if 4.7.

Lookin good!

Well ... well ... I got a little ahead of myself and decided to go for 4.7GHz this evening ... after passing 10 tests with Intel Burn Test the max temps were

 

69C Core 1

72C Core 2

69C Core 3

70C Core 4

71C Package 

 

As per NickN I set CPU CORE VOLTAGE OVERRIDE to 1.37 in the UEFI BIOS.

 

I don't think CPU-Z can be trusted at these frequencies ... the Core Voltage is being reported at 1.904V ... :excl: ... don't think so!

 

HWMonitor is showing a voltage of

 

IA of 1.403 

VID of 1.372V

+VCCSA of 1.176V

CPU Vcore of 1.408V

 

I am cautiously optimistic that 4.7GHz is maintainable ... waiting for NickN to finish so I can stability test as per his instructions.  It looks like Ryan Marziaz's cautionary warning to another forum member about 4.7GHz not being achievable on a Haswell system didn't take into account delidding, lapping, CLP, Corsair H100i and NickN.  My hat goes to Ryan ... if it wasn't for his post I would have never shot for 4.7GHz.  I'm serious Ryan, I thank you very much for what you do on the forums ... between you, HLJames and NickN I finally got a system I can be proud of.

 

Hopefully people will be able to use some of my illustrations to achieve this type of speed for themselves as well.

 

Succinctly put ... WHOOOOO HOOOOO!

It kicked the bucket at Vcore 1.37 on a short flight from KBNA to KATL ... upping to 1.38V.

 

I'm wondering ... if I keep upping the voltage (probably won't try and go any higher than 1.41V) and it is still not stable does this mean that the chip has hit the wall and my OC'ing must stop at 4.6GHz ... or does it mean that some of the other settings need to be tweaked to make it stable?

Study how the FIVR moves the voltages between 3.9 - 4.6 GHz then disable SVID.

That will give you a very good guess what voltages should be at 4.7 GHz, where you must manually set all voltages.

The biggest movers are VCCIN, IO-D

Same with cache voltage for cache speed.

I finally got a successful stress test at 1.42V using OCCT 4.4.0 CPU:OCCT 64-bits Large Data Set ... temps never got out of the 70s.

 

I think, based upon the voltage required for 4.7 that I've reached the end of the road for this chip ... fine by me though ... 4.7 is pretty good.  Now I have to start increasing the NB Frequency from 39 to 40 to 41 ... etc.

 

Thanks for your expertise!

Oof, looks like I got the bottom 50th percentile 4770k.  Made it past POST, didn't make it all the way into Win7 at 1.2V and 46x.  Can't even get 42x, trying (and struggling) with 41x currently...seems like I'm temperature-limited with some BSODs for anything 1.2V and above for 42/43x with a Hyper 212 EVO.

I appear to have a Horse shoe somewhere I just completed my 4.8ghz  AIDA64 stress test  at 1.39v max temp 78c and OCCT4.4.0 max temp 72c. NB is still 41 but I don't think that is a big deal. I haven't tried to raise it yet.

Definitely do the Heat spreader MOD on that one or perhaps try to exchange it.

The difference between 4.5 and 4.8 is no more than 2fps in heavy scenery. That difference is more about bragging rights than performance. I hope you are referring to NickN's guide!

Digging this up - I just installed my 4770K and the H110, at idle with stock speeds I am getting between 33-37°C, are these temperatures normal for Haswell? 

If at idle, are the fans PWM? If so they are probably ramping down. In either case, that's an okay temp for idle. Load is what matters.

Mine is at 4.7GHZ (winter)(4.6 at summer) at 1.25V and stable in FSX but temp is up to 84c (avg 65-70). 

 

I dont think it is stable in Prime 95 but i dont care as long as FSX is fine :-) (+14hours)

After I posted here I increased the fans RPM (not much increase in noise as they are Noctua fans) and CPU temps dropped significantly by 11°C, I over clocked to 4.6GHz with voltage at 1.220, I haven't been able to test whether or not it is stable, I will tomorrow. Temps only increased by 7°C which isn't bad, it is now running idle at 35°C.
