Also Haswell OC can take some time, to find the right voltage settings.

good luck smile.gif

Edit: Uncore/Cache Ratio: x38 1.28v 1.28 is too much for x38 should be something around 1.15 probably less.

Nices tips. I find Higher vrin would increase temp. Is this right?

Also, from my readig some haswell don't like high vrin? If i limited by the vrin, i can do much with cpu. True or false? Thank you.

And may i ask what consider golden chip in haswell? The standard ?

I ran for almost 3 hours before my AIDA trial ended, but like I said: I took screenshots on the hour and here's the 2 hour mark. I couldn't find my processor retail box but I remember it was a Costa Rica chip.

Username: f3nd3r
CPU Model: 4670K
Core Multiplier: 49
CPU VID: 1.360
Vcore: 1.376
Input Voltage: 2.000
Uncore Multiplier: 40
Uncore Voltage: 1.100
Cooling Solution: H100i push/pull, delid
Stability Test: AIDA64 for 2 hours
Batch Number: Costa Rica
Ram Speed: 1600 9-9-9-24
Screenshot (Click to show)

This is what i've talk about. Look at the cpu and north bridge minimum clock in Aida64. And i bet that pcie clock went the same way. Is it something wrong when this happens? Is this instability or is this "normal" ?

Hi guys again, i'm trying now with 4.6Ghz 1.35Vcore and uncore/cache ratio default, but it doesn't works anyway, i get BSOD with AIDA test

Please Post the following or people can not help you properly: wink.gif
Vcore and Core Multi/Frequency
Vrin + LLC level
Vring and Uncore/Ring Multi/Frequency
Ram voltage,Frequency and Timings
also fill out Systeminfo please. To make sure it is no Hardware error.

With my tested CPU's it was always a little bit. Tested 3 I5 and one I7 so far.
I make experience that too high Vrin can mess up stability. I think best is to keep it as low as possible but that requires methodically testing. And unfortunatly many people just don't do that. They just set a high value and wonder if that is not working. To get stability with low Vcore you will have to do a lot of testing and only one setting at a time.
4.9-5.0 GHz with Vcore below 1.35v is certainly very good.

And also post bluescreen code, Peybol, always. So many people say "it doesn't work" or "it crashed" or "i got bluescreen" but that doesn't say anything at all about what the problem is, it's just a statement. 124, 101 and 9c are the most common ones

The problem is that Windows 8.1 doesn't shows any code on BSOD, then i can't give it to you.

This is my actually config seems stable, atleast it passed AIDA stress 15m

Vcore and Core Multi/Frequency: 1.37v x46~4.600Mhz
Vrin + LLC level: I have an Asrock motherboard, that values are unknows for me
Vring and Uncore/Ring Multi/Frequency: Uncore/Cache ratio at x38 with 1.1v (override)
Ram voltage,frequency and timings: All default cause i don't wanna modify them until i don't get a stable OC

I can take some screens from and Asrock utility for Windows, so you'll can see the different values from my MB

Thanks you!

Vrin or Input Voltage is CPU Input Voltage
Load Line Calibration is CPU Load-Line Calibration look in bios for those values
What Ram are You using ??
