Overclocking i5 4670k problems

[brybell]

Hello,

I have a 4670k and a msi g45 gaming mobo, I can get it to 4ghz without messing with the voltage ( I think I have it set to auto).

Anytime I try to bump it up even to 4.2 or 4.4, I got a BSOD. 4.2 was stable only until I stress tested.

I have a 600w PSU, could that be the problem? It doesn't seem likely...but I am not sure.

Anyways, what would be the best settings to get to 4.2 or 4.4? So many options in the Intel Extreme program, I am not sure what works and what is causing the BSODs.

well, disable the auto voltage and increase it your self, that is probly the problem. try 4.0 ghz and increase the voltage by 0.025 volts and test for stability. then 4.2 ghz and another 0.025 volts.

I would not take the volts over 1.4, well personally i wouldn't go over 1.3... 1.3 volts SHOULD get you to ~4.3-4.4+ unless of course you got unlucky with your chip, you might not be able to get over 4.2 at any voltage if that is the case.

Thanks, after getting the BSOD the last time and having trouble rebooting afterward, I am a little scared to keep messing with it. I did read anything over 1.3v is a little worrisome. I will post a screenshot of my settings when I get home. Might be a little easier to help :]

What voltage should I start at?

1.175 v. is a good starting point.

that should help, probly better than i could. if you cant achieve that, then knock the multiplier down by 1 or 2 and keep voltage under 1.3

Thanks! When I tried setting OC settings in the BIOS, most options were locked and I was unable to alter them. Do you know why this would be?

 

[Danbuscus25]

that means your mobo doesnt have those options. you can do it just by increasing the multiplier and the voltage

Really? If so, that is somewhat disappointing since it is a mobo made for gaming and overclocking.

 

[Danbuscus25]

the settings in the link i posted are rare, most gaming mobo's wont have them and will just configure those automatically. i would try 4.2ghz at 1.25v and run a stress test, such as prime95. if there arent any errors after a while, try 4.4 ghz and 1.27-1.29 volts. however, if you have the stock cooler i wouldnt go past 4.2, and try to keep temps under 70c.

Ok thanks! So right now at 4ghz I am at 1.150v max, currently hwmonitor says its only .765v (dont know if this matters). BTW I have a Corsair h100i, at 100% load I think it hit 70ish under prime95.

Look at this:

Should I disable any of the settings I have enabled now? Thanks! Really appreciate the help.

 

[Danbuscus25]

it looks fine, you can try for 4.2 ghz and increase voltage to about 1.2v ish and run prime95 again, and if it is stable and stays under 80c, its fine, and if it is between 70c-80c, turn the cooling up high if possible, if not then just monitor it.

ok thanks, should the "Core Voltage Mode" be set to adaptive? That doesn't override when I set the voltage from default to 1.2?

I just noticed that when I test with aida64 my voltage goes up to 1.255v.

Should I increase it to at least that then? And based on this http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics
it says I should change core voltage mode to static I think..

So after seeing that I was hitting 1.255v under load, I set a fixed voltage at 1.2, increased the multiplier to x42, and I am stable running aida64. Now that I am actually using less volts, my temps hit a high of 73 and I idle around 30c, even with normal load I never really get above 30-40c. Pretty much the same as when I was only at 4ghz but with more volts. Thanks! Should I try 4.4?

You're looking good! 4.4 would be pretty safe with your Core Temp at only 73*C. I say go for it! You may have to increase Vcore though. Just don't go over 1.300 v. Vcore.

Thanks! The only thing that worries me now is that is 1.2v safe to be running all the time? Now that I ran Aida64, should I go back and turn the voltage back to adaptive?

 

[Y0GI]

That is how I run: Static or "Override" mode for stress testing and Adaptive for normal usage. I also use the "Balanced" Advanced Power Option in Windows. That way, the CPU slows down and Vcore is reduced during periods of low CPU demand.

Yogi

EDIT: 1.200 v. is quite safe.

yes, 1.2v is safe, and with your temps and stability, you can go for 4.4, maybe 4.6 even. but, dont go over 1.3v and try to keep temps under 80c if you can. you must have gotten a lucky chip to idle at 30-40c at that OC

At idle the CPU downclocks so dosn't matter what your OC settings are my i7 is @1.22 volts and 4.4 Ghz and idles around 25-30c... max temps while gaming are low 60's (normal gaming temp is 40-50) and stress test is mid 70's.

Well I said under a normal load its at 30-40, idle its 25-30. Never gets above 70 under 100%.

 

[Danbuscus25]

thats great

 

[brybell]

So, I increased 4.2 to 4.4 and increased the voltage from 1.2v to 1.22v and it BSOD before I could even stress test. Why is this?

Its confusing to me because how could i be stable at 4.2 and 1.2 and then only increased a little its not only NOT stable, but it BSOD's. Weird...

Also, after it BSOD's and reboots it doesnt show the BIOS and I see a black screen with text that says settings have been reset and press f1 or f2 to contiue etc.....however it doesn't work with my mechanical keyboard, and I have to unplug it, and plug in a $19 one from target in order for me to be able to press f1 to continue. Very odd.

I am afraid to attempt more OC with this outcome only pushing it a little further. What is everyone's take on this?
