Making Sure My OC Is Stable

[Lobialkon]

Hello everyone!

So, two days ago i installed my new Ranger VII and I5 4690K and today i started messing with the OC (I had a 3570K OC'ed for 4 years and was forced to change because of a ****ty motherboard). And i wanted to make sure everything is set properly and to know if there is anything i missed.

I started changing the AI Tweaker from auto to XMP, increasing the multiplier to 43 and the vcore to 1.150 . Then while booting to Windows 10 i got a BSOD, back again on the BIOS i changed the vcore to 1.200 .

I ran prime95 (v26.6 as ive read newer versions give exagerated high temps) both blend and small FFT for about 15mins each without BSOD nor errors, and the max temp was about 68ºC. Then i played some games for about 20mins without issues and i went again into the BIOS and set the multiplier to 44.

Once more, i ran both tests, with the same temperature result, and i played a little bit and it was also fine. (While playing the max temperature is about 55º more or less).

Sadly i dont have more time to keep testing, ill continue in a couple hours, but i wanted to make sure if there is anything else i should be trying or switching on the BIOS, because i remember on my I53570K i had to change the LLC to make sure the vcore wouldnt drop and change a couple things that would help with the temperature, and now, i just switched those two and nothing else and is working flawlessly, maybe i forgot something? or i dont know!

My specs:
Maximus Ranger VII
I5 4690K
Hyper 212 Evo
GTX 970
2x4GB DDR3 1600mhz Kingston
HDD WD 1TB
620W Plus Bronze Seasonic PSU

Thanks in advance for any info you can give me about the subject!

Fortunately?unfortunately? OCing can be that easy! 😉

...sure you can tweak and tweak...

If you want to set LLC to some medium value instead of leaving it on auto go ahead...vdroop is a protective feature that is a good thing. If you don't want it set a high value or leave auto...

Once you have your stable voltage for a given OC enter that value as adaptive voltage to get speedstep working so voltage can drop when idle....

I remember when OC'ing my I5 3570K the vcore would drop and change a lot, and i could "fix it" with LLC, but as far as ive seen with the 4690K, its rock solid at 1.199 and it wont move from there, so im not sure if i need to set up the LLC, it seems okay.

About the adaptive, for the voltage i already set, instead of setting it on manual i put it on adaptive? So when its on idle it will drop to something low and when its under load it will go up to 1.2? Cant that make BSOD happen?

Thanks!

So, i played for a couple hours without issues.

Now, i played the same game, and 15mins in, a BSOD about a WHEA error, thoughts? Should i increase the vcore a little bit? I want to increase it just a little, but it wont let me, its either 1.200 or 1.250, cant i set it to something like 1.210?

Thanks in advance!

EDIT: Found out it was by pressing "+", i set it to 1.205 now, stress testes for 20mins without issues, tomorrow ill see how it behaves while gaming.

Speedstep should work fine if you have a stable system...if the system is on the edge transitions from idle to load or the other way round might cause BSOD but you don't want to be on the very edge anyway. Likewise, eliminating vdroop to keep constant voltage is probably not smart 24/7 OCing. For running high clocks and passing a benchmark maybe but for general computing gaming you want these things working.

less voltage/current over time is going to keep your chip healthy

WHEA...often vcore....sometimes RAM....I'd try vcore first

Another WHEA_Uncorrectable_Error BSOD, again while playing, during stress test everything goes just fine, i ran it for 40mins more or less without issues, and gaming also goes well, its just random behaviour, i can play for 2 hours, 3, nonstop, whitout issues and then, 10mins in, i get a BSOD.

Is there anything i can do to try and test if its the ram failling?

Thanks in advance!

Hello Lobialkon

I'm with Arne try adding a little more vcore, 8GB of 1600MHz ram should run easily without any tweaking. You could also try running in manual mode instead of adaptive. The only drawback is the voltage doesn't drop when the cpu is idle, which isn't a big deal it will add a few more dollars to your electric bill maybe but it won't hurt your cpu.

I run mine in manual mode.

Thanks a lot nate! I read someone else's post asking for OC info and you wrote a lot of useful information that i used!

I now raised the vcore from 1.205 to 1.220 and see how it goes, if everything goes well for a couple days maybe i could decrease it a point or two and see then how it performs! I never used the adaptive mode, always on Manual, i was just asking if it was worth using it, electric bills aint an issue in my country so no worries about that!

Thanks a lot!

You're welcome

Yeah see how it goes with the added vcore it might be all you needed, then if it's stable as you say you can lower it a little.

Give us an update if that solved your BSOD's.

Highly recommended that you use RealBench vs. Prime95 to determine OC stability.
