please guys i need some help

Specs :
i7 3930K
Gigabyte x79 UD3
2x8 GB HyperX Fury 1600MHZ Dual channel
Galaxy GTX 680 4GB GPU ( but it won't matter much here)

i can't oc my i7 3930k even to the slightest levels , aside from 3.5 to 3.8 of turbo boost , when i raise the levels of turbo boost to anything over that , say 4ghz , it fails to post and i have to clr cmos to boot , it works well on stock turbo boost , changed Vcore to 1.3 and it does same , pc works like once and when i turn it off and cold boot it never posts , so what's the problem exacly? :(

This album has the settings : https://imgur.com/gallery/BgSMC96

please help me guys cuz this is so so frustrating ..

I might be mistaken butyyiu don't want to up your turbo boost speeds, you want to up the CPU speed.
You don't need turbo boost when overclocking, you want to set the normal cpu speed higher, and turn boost off.

so u say i turn off turbo boost and raise cpu multiplier? i will give it a shot when i'm home

Yeh it's the main cpu multiplier you want to be increasing (with a voltage increase as nessesary).

Any joy?

Still away from home , on a trip , going home tomorrow , but let me review what i will do ... see this pic .. is that right? or should i change any other values?

Yeh leave the boost on auto or disable it if needs be.

You want to increase the main CPU speed (multi) .

The turbo boost feature is a bit of a fallacy in the context of overclocking..

Bare in mind you might need a cpu vcore (voltage increase) .. I tend to whack it straight up to 1.4v or 1.375 just to rule out a power delivery issue ... You can then tune it back down a bit depending on temperatures and personal preference

so i made what you said .. same issue ..
i raised CPU to 40 , and Vcore to 1.3 , pc boots very well , no issues at all , restarts also well , but when i turn off completely it gives black screen , just black screen and nothing happens
HOWEVER ... i left it like that for a minute , then i restarted from the restart button , nothing happened , left it for like 20 seconds then restarted again and it worked .... tried that like 3 or 4 times to confirm , not always work after the second restart , but i have to leave it work for like 20-30 seconds before i try to hit restart button , i also noticed that cpu fan speed raises faster like it does while it's in Bios during the Black screen ... so what does all of that indicates to? any help? as i don't know how safe it is to run the PC with a lot of restarting like that ...

When i set everything back to Auto again it works perfectly with no issues , when i just increase any value in Multiplier even for only extra 100 mhz it does that weird thing it does , black screen , no post , fan behaving weird , and it works after couple of Reset button clicks .. i'm lost here lol

i also did UP VTT to 1.1 and it did no difference , so idk :S

Update : did over 4 hours of Prime95 and it's stable as hell , temps maxes out at 61 c , but every time i shut it down i have to restart it 2 or 3 times and i have to leave each one for around 20 seconds then restart till it works

haven't heard out of you .. tell me what do you think about my last quote :S
 
Raise the vcore to 1.375 or 1.4.

Keep an eye on temps obviously. But it would be useful to rule out a low cpu voltage issue.

Edit your chip is running quite cold.. So there's no harm in upping the voltage to rule out a power issue
 
Just bear in mind, more vcore means higher temps. You say you are hitting 60, I wouldn't worry before you hit mid 80.

The chip can run at 70/80c, it's within the safe temperature ranges.

People seem to get obsessed with having cpu max temps in the 50's/60's but it's not a realistic target if you are overclocking on a air cooler.

well , i've made it up to 1.35 and the problem still there , idk why it behaves like that , i even restored defaults , turned off Turbo boost then made the cpu multiplier from 3.2 to only 3.3 and it did same issue and it wouldn't post unless i restart the pc couple of times 30 seconds from each restart , so basically it does that on any change at all , even the slightest .. it's the weirdest thing i've ever encountered , but well it's my 3rd day to run it like that , 41 multiplier on 1.3 vcore , i don't quite turn off my pc unless im going to work so i just keep it on till i go to work so it wouldn't hurt me to restart it 3 times till it work ... the thing is that idk if that would harm the pc over the long term or not :")

Not sure to be honest, I'm not too familiar with that chipset.
Maybe someone else could comment.. Any YouTube overclock guides for your chip?

no one bothers to answer :"D
well , it's been over a week i think and i do this thing everyday , pc is working fine , wish that it's not harmful to the pc :"
