Hey everyone,
Well I'm desperate now, cant sleep and cant figure out whats wrong with my brothers Xmas PC.

PC spec.
I5 4670K
MSI G45 gaming MOBO
Corsair vengence Red 2133 ( 2 months tested in my PC)
850 watt OCZ PSU (2 Month tested in my PC
AMD 7970 ( 2 Months tested in my PC)
Windows 8

Here's the problem, its something i have never seen before with overclocking.
When applying a stable overclock of 4.2 at 1.25 Vcore (stable 4 hours of guild wars 2, 5 hours Crysis 3, 3 hours Battlefield 4 MP and 2 hours prime and aida) on a cold Boot after about 15 minutes of idling the PC will shut off instantly and the say Previous Overclock was unstable.

I can then load my OC and off i go for as long as 10 hours Idling, gaming, facebook, youtube its stable.

But every day on its first boot it will cut out completely after 15 mins and show that message.

can any one help?
please if you need to know more i will be on here ready to instantly reply

Thanks
 
Hi,

The voltage of 1.25 seems quite high for 4.2ghz TBH. Usually 1.25-1.3 is for 4.4 -4.5ghz using the 4670K.

I have a 4.2ghz OC and am using just 1.151v core.
 
try disabling c-states in the bios, check all temperatures... also make sure the motherboard has the latest bios

Bios is latest from msi website.

It is high i thought that as well! Unfortunately it took 1.245v to get stable at 4.2. Otherwise i would just BSOD when gaming or stressing. Not a good chip but i can cope with that as temps arent getting passed 75 on intel burn test. Gaming i'm seeing 64 max so really not a problem there i would have thought?

All C states and EIST are disabled in bios. Thats my normal overclock routine and normally works fine.

Just in case anyone was wondering. The PC will NOT freeze after a cold boot when default bios settings are applied. Idled happily in stock form this morning for half an hour before work.
I applied the overclock switched off and left.
Got home booted up from cold with overclock applied and in 13 mins cut out with Precious OC failed message.

so what do you guys think?

This is interesting. You obviously have experience with clocking and have good knowledge. :D
You just mentioned it's absolutely fine when stock. So something in the OC is causing it. I can't say why it's just appeared but something is not settled with the settings applied.

You may need slightly more v core ? Sounds odd but entirely possible in this case. I had the exact same thing when stabling my 4.2oc , had v core at 1.13 but on idle it would restart on times. Stressing was fine and seemed stable but kept have the occasional restart especially when idle. I upped the v core to 1.15 , changed the multi on the uncore to 38 from 34 - this helped a lot. Also added my uncore voltage from stock 1.5 to 1.58v. Now it's not had the issue for a month.
Bearing in mind you mentioned about the core voltage required on your CPU , it's going to be picky what and where it's getting its power.

Post up all your clock details so we can have a good look through them. :)

Looks like memory sticks are put into inappropriate slots. Did you check it if they sit correctly ?
More BIOS screenshots would help to see what you've got there. Try to switch EPU option, SpreadSpectrum and set LoadLineCalibration to high.
 
Bumped vcore up to 1.27 last night. Still cut out this morning after 16 minutes idle.
Cant't post screenies at the moment as i'm at work. apologies.
I tried resitting the ram and using a pair of geil sticks to no avail.
When i get home i will post all the settings.

I think EPU might be an ASUS setting? Can't remember seeing it in the bios of my MSI board. If i'm right in thinking, EPU is to do with the power phase settings. The MSI board has Adaptive power phase settings. Whatever the case a google search seems to suggest its a power save feature so will look into that thanks.
i thought spreed spectrum was for noise control. when you say switch does that mean on or off. happy to try it :)

LLC was something i thought you wouldnt need with haswell. of course i could be mistaken i'm only recieting what i've read online but doesn't haswell have next to no vdroop? like i said could definatly be wrong. So what would a good setting be?

Also you may be interested in this.
I have found other people with my problem
unfortunately they all give up! and switch boards

will have screenshots as soon as possible

cheers for the responses:D
 
update...

cant take a screenshot as i don't have a memory stick anywhere in the house. ridiculous.

Well after setting everything to auto except vcore at 1.27v X.M.P enabled and multi on 42 I thought i was stable. then leaving it to idle after 2 hours cut out and rebooted. Running out of time to get things ordered now.

If I can't fix this, which it seems no one else has, I might have to considered a new board.

So any suggestions for incredible stability whilst OCing? might have accepted defeat.
 
for cold boot issues try a touch more imc voltage and or dram voltage (might be called vtt for integrated memory controller)
 
update...

Now realised this isnt just a cold boot issue. It is more of an idle issue.

When I say idle I mean web browsing, listening to music, leaving it and coming back to it, and downloading, in fact it may be a coincidence but happens a lot when I'm downloading. Poor SSD:(

Dram up to 1.6V from 1.5 XMP settings.
It still cut out whilst iwas writing this first time round. lol
If we can find a fix I will shout it out and get this known to MSI as I have seen at least 6 people. on forums with this exact issue.

(sigh) should i have gotten him a ps4 instead? lol

cheers for your help as always
 
Have you changed any uncore settings ?

Id try this - 1.3v core for cpu.
make sure your uncore multi is 38x not standard 34.
raise your uncore voltage to 1.1v

worth a shot ! Good luck

Hi,

As you state this may be an idling issue, this indicates to me that it is either the power supply or the motherboard.

The new generation of CPU's from Intel have a slight reputation for power supply incompatibility when running at low clocks (new Intel CPU's draw very little idling), just because the turbo is running up to 4.2Ghz does not mean that that is the complete issue. For example the power supply may have run quite well in your own system for two months, but does your system contain a 4670k? If so might I suggest another PSU to test this issue, one that is also ratified to run with an Intel 4670k.

Its a good point Haswell has had a few PSU issues. :D
 
Can you still DSR/return the motherboard? If you can I would do so and not bother with any of this in all honesty. Otherwise good luck in getting it sorted and if I think of anything i'll pop back into the thread and suggest it. :)
 
Normally I would head straight to the psu but its has been running with the exact same Mobo and an i 7 4770k at 4.6 Ghz in my personal rig. For 2 months without a hiccup.
I even put it back into my rig and had no issues with it.

Today is day 17 of owning the board and I5 from OCuk so i just missed the DSR period and the only reason for that being that i was going to build this PC in front of my brother Christmas eve but then thought better not as it could have a faulty componant. ironic much lol.
Spoke to them on the phone and I can't return it for having issues with over clocking (which to be fair thats right, in stock form its fine)

However, all this being said I was looking through forums again seeing what i can unearth and found this.

"Thanks! My system been stable since my last post - no more shutdowns - running 4.3 @ 1.25v, with a similar setup to yours: leaving everything auto except multiplier, vcore, and XMP. I haven't touched any other settings, not even vdroop. I'm waiting to really confirm no spontaneous reboots, before getting too excited, but it seems like the problem is gone. Not sure whether it's the raised vcore, or leaving most everything auto."

This was the last post he made, which made me think, if it worked he might not have confirmed it as he had nothing to worry about and couldn't be bothered to report back.

(ugh long post) soooo...
settings...
reset to default
42 mult
1.25 vcore
XMP enabled
everything else auto.
This has been running for 5 hours now and touch wood its stable, in idle too.

WHHYYY. anyone think they could guess why this has helped? because i have no idea. MSI bios must know something i dont!
