Haswell Overclocking Guide [With Statistics] - Page 383

post #3821 of 19539
RAM 1600 XMP
Vcore 1.360v
VRIN 2.0v
uncore auto( since its on 34x)
SA/IOD +.010v

50x

All it does is make it to the windows loading screen where it craps out, perhaps i should open the window and see how far this turd flies rolleyes.gif

I have Z87-A and pretty bad CPU (4500 @ 1.34 V) but I could leave all other voltages on AUTO (the motherboard seems to set other voltages pretty good - yours should be the same or. even better regarding the AUTO parameters).

I am on XMP too at 1866.
fsb:dram ratio on Auto..
I was setting it 1:1 when ocing my old Q9400 it was giving best performance in the old time.
Where is the old FSB ocing.Now x50 time I see.CPU strap 125 = BSOD and BCLK = 102.5 bsod too smile.gif

Lowering dram frequency 1866 to 1600 helping oc or tempratures?

When you're still trying to find stability with the core and uncore/cache, it's better to downclock your RAM, that way you have less variables. Once you get the core and cache stable, then you can enable your XMP profile or start overclocking the RAM. This is especially true considering the fact that an XMP profile is basically a set of pre-programmed OC settings....

Anyone using Fritz Chess to test stability?And how reliable has it been for you?
I started using this as apparently its more real world load test.Up to 4.6Ghz I used Prime 95 but as i up the volts I'm wary of it,even though I'm able to use less vcore at 4.8 than at 4.6,adjusting the CPU Input Voltage really seems to help the other voltages remain lower if you hunt for the sweet spot.I even have my Uncore Multi at 43 and RAM ever so slightly above rated as I set BCLK at 100.4,sounds crazy but that .4 seems to help with stability,although I'm sure it has nothing to do with it.Has anyone else found strange tweaks to BCLK help thier overclock stability?

You can always go with Crysis 3 or Far Cry 3 - they'll certainly test out your OC settings, as well as letting you actually do something during the testing....biggrin.gif

A noob question here, Is it possible to OC an i7 4770 non K series? If yes, how far?

From what I've been seeing, Intel has locked down overclocking on the non-K series chips....

So Its a no. Thank you for the quick response. smile.gif

Yep, that's what it looks like - http://www.guru3d.com/news_story/intel_haswell_almost_entirely_limits_overclocking_to_k_series_cpus.html

Thanks for the link, atleast some features are not present in the K series. thumb.gif

Hey guys, I need some feedback from the experts here regarding my OC.

Here are all the settings I changed:

Multi 46
Vcore 1.245
Uncore multi 43
Uncore Vring 1.2
CPU VRIN Override LLC Extreme
CPU VRIN Override Voltage 1.85
Memory XMP
C1E, C3, C6/C7 Disabled
EIST Enabled

Run AIDA64 with the above settings but 1.24 Vcore, crashed after 80 minutes.
Run AIDA64 with the above exact settings, crashed after 4 hours 10 minutes

Maybe if I add 0.005v to Vcore (for a total of 1.25v) then it should be ok. Or do I have to tweak other settings/voltages? How can I say which voltage needs to be raised?

I feel like I am pretty close to stabilizing it, just need like another day of testing.

Regarding temps, I never saw them go above 74, they were averaging high 60's/low 70's, max temps were 81-83 across all cores, they must have spiked like once or so.

Looks like I have a decent chip, what would you advice me to do? Leave it as it is, do some more tuning for an even more stable 4.6Ghz or push further? And something last, bus is set to 100Mhz but CPUZ shows it's like 99.70 and that drops the frequency to 4589 instead of 4600, how can I make this a round number?

Thanks in advance.
