G3258 - Can't get it passed 4Ghz

Also check the bios there were bios updates for this chip.

1.3 volts should be enough for 4.5 ghz.

Set uncore ratio to 33x not 32 the default it can cause instability on some gigabyte boards

Set VCCIN to 2.00 volts this is probably why your oc is falling down http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics

On my old g3258 I found 4.5ghz at 1.278 adaptive voltage vccin 2.00 uncore ratio 33x uncore voltage at auto LLC on highest setting turbo

you're not using the xmp for ram i take it ?

XMP for the RAM was disabled

I copied your settings exact and it wouldn't boot, I reset it from the bios and I just get a mouse cursor that doesn't move - No BSOD or anything
 
Most people use 1.9-2.1 vccin for stable overclocking

My setting of 1.278 volts was adaptive voltage not manual

Helps if you swap to the classic view in bios I think its f2 to switch to classic

Yeah I was in classic view, for some reason you can't change Loadline in classic view though

Maybe my chip just won't go passed 4.2Ghz
 
For my case, I was trying to get x46 core multiplier and could not stabilize. Odd, considering x45 was rock solid @ 1.35v. I scaled up voltage from 1.35 to 1.4, 1.42, 1.47, 1.5, 1.512v, without being any more stable as voltage went up. The key was a higher Vcore, AND a higher input voltage. I demonstrated this by testing stability at 1.42v with various input voltage. I tested by running x264 until Bsod 5 times per setting, keeping track of averages. From 1.85 to 1.95 to 2.05 to 2.15, I could see demonstrable improvement in stability, with a higher maximum, minimum, and average time until Bsod. So what is this saying? Often times we are just tempted to test the Vcore and if it doesn't work, just get a higher Vcore, and higher, until we use ridiculous voltage and still crash, where we then put our hands in the air and give up. Just chucking Vcore as high as you can will often not net stability if you do not have high enough input voltage to match that high Vcore.

from the guide and make sure you're on latest bios for the board 1.3 and vccin at 2.00 volts should be stable as a rock for only 4.2ghz you must be overlooking something
 
2.1 is perfectly safe wouldn't go much above that though also important to have uncore at 33x NOT DEFAULT or auto 32x.

All power saving features disabled
Turbo disabled
1.3 vcore
uncore voltage = auto
VCCIN= 2.15 or whatever is +1 up from 2.00 on your board
Uncore ratio = 33x
cpu ratio =42x
LLC = turbo

btw which bios are you on is it the latest ?

Must be a a bad clocker is only thing I can think of bar overlooking something, most should be doing over 4.2 ghz on 1.3 volts.
