Adaptive mode problem, blue screen!

I have an overclock on an Asus Z97K with an i5 4690K of [email protected].
It is stable on Prime 95, 2 passes of 15 hours each, the hottest core reaching 79, idle is 32.
I ran OCCT for 6 hours but the temperature was peaking at 85 so I got a little windy and stopped it.

I've gone back to AiTweaker in BIOS and set adaptive mode for cpu voltage but when it tries to boot into Windows I get a blue screen.
I've obviously missed something but for the life of me I can't fathom what, any ideas most welcome.
 
1.26 seems low for 4.5ghz don't haswells tend to need 1.3 or more and 2 volts VTT and make sure not overclocking the uncore as it seems to make little difference.

I'd recommend asus real bench and gaming and intel burn test for testing.

Prime is all well and good but I've had prime stable an hour fail in 1 pass of asus real bench and games but all about using them all really a combination of many stress tests and games.

A good haswell guide here http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics I'd say make sure you run uncore at 35x the default 4690k frequency Can raise tweak it later but as in the guide overclocking the uncore doesn't seem to add much performance.

Best to set it manually and at least 1.9 vtt but I'd personally expect 4.5ghz + to take more in the 1.3 - 1.4 voltage area and maybe even 2.00 VTT depending on other tweaks you can do.

Na they rarely need that much voltage bud, i suspect when ya changed to adaptive you didnt set an offset? You'll need to increase the offset untill you reach the 1.26v target you found worked on fixed voltage.

Just stick the multi back to 40 and leave the voltage on adaptive and see what voltage its reporting under load, lets say its 1.2v, the you would just set a +.06v offset.

They vary. From the prize chips that can do 4.5GHz @ <1.2v, to the good chips that do 4.5 @ 1.2v, to the decent chips that do 4.5 @ 1.25v, to the worst of the bunch that struggle with 4.5 @ 1.3v.

It seems his chip is a decent one. Mine (4770K) needs 1.31v for 4.4GHz and won't go higher unless 1.39v is pumped through it (only did it once for a 4.5GHz bench).

Ditto. Some Handbrake too.

Think you mean VCCIN (Input Voltage). VTT on Haswells (memory controller related) should not go higher than say 1.25v. Increasing VCCIN doesn't do anything for me. Results may vary I suppose, and worth trying. At 1.8 VCCIN it can cope with the 1.31 Vcore + 1.264 Uncore on mine (4.4/4.3 Adaptive).

Screenshots of the BIOS settings would be good. Hard to tell what's going on otherwise.
 
Mine does 4.5 @ 1.25v, which is an + 0.160 offset for my chip. It will also run at 4ghz with an underclock from stock voltage, which is a really nice setting.

yea vccin sorry am in lynfield overclocking mode

I needed 2.00 VCCIN to get my haswell fully stable at 4.5ghz I found that under 2.00 VCCIN required a lot more vcore vs higher vccin

Worth keeping BSOD Codes-

BSOD codes for overclocking
0x101 = increase vcore
0x124 = increase/decrease vcore or QPI/VTT...have to test to see which one it is <----- Almost always QPI...
0x0A = unstable RAM/IMC, increase QPI first, if that doesn't work increase vcore
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = QPI/VTT, increase/decrease as necessary
0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust QPI/VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
System Freeze = Usually increase V-core and test for improvement.
