First time overclocker, please help! :)

[Novak]

I've been watching Linus on YT for over 2 years now, build my first computer March 2014 and is as follows.

 

CPU - Intel Core i5 4670k
M/board - MSI Z87 MPOWER 
RAM - Corsair Vengeance 16GB 1600Hz 
GPU - Gigabyte GTX 680 2GB OC'd in SLI 
HD's - Samsung 120GB/500GB SSDs + Seagate 1TB 7200rpm + WD 3TB 5400rpm External 
Case - NZXT H440 White 
Cooling - NZXT Kraken X61 
PSU - Antec 850W Modular HCG-850M 

Monitor - Primary - Asus Swift PG278Q 
- Secondary - Dell P2714H 27" IPS 
Keyboard - Ducky Shine 3 cherry browns 
Mouse - Razer DeathAdder 
Headset - Razer Tiamat Elite 7.1

 

Being a novice and my first build i just pressed the OC Genie on the MSI mb and left it at 4ghz on all 4 cores until 2 days ago, after watching years of overclocking videos and chatter on the internet i decided to give it a go manually myself. Knowing i had a decent enough computer do try it safely via the motherboard bios. 

 

Things i have picked up include setting the Intel C-state to DISABLED so the boost doesn't work. along with CPU ratio mode to DISABLED so the cores run at the same speed together. Then it was a matter of upping the volts and CPU ratio/frequency and test in test stress programs, im using AIDA64.

 

What i've managed to accomplish so far. My aim is 4.5GHz, which i've got at 1.295v which reads at 1.320 in AIDA64 with linus's tip of the CPU not going on or over 80dg, i have it under stress around 70dg and when playing games it sits around 60dg. But i only get 30mins into the AIDA64 stress test before it crashes.

 

How can i get stability? more/less volts? Tune it back to 4.4GHz? or any advice to have it working correctly would be greatly appreciated. 

 

EDIT: one thing i did not touch was the ring ratio and left it at 38/3800, if changed would this help stability?

@Novak

Linus made a video just to serve this purpose:

While you can't exactly 'follow along' considering he uses an Asus board and the BIOS is different, you can basically compare your results to his, and follow his methods.

 

Hope this helps

Already watched it 10-15 times, but thanks

 

When it crashes at 4.5hgz has i mentioned it does not over heat/thermal throttle. It's just unstable. Not sure how to adjust as i feel its almost right.

add more voltage.

More voltage. When you reach 1.3V, that's usually the limit. Your CPU will be around 80C under load (which is quite hot imo) and when it gets unstable, then it's time to dial back .1 or .2 Ghz. Depends on it passes the stress tests.

[Novak]

okay thanks, should i try adjusting the ring ratio at all?

Found a forum with a guy that has tested several results.

 

This could help you get an understanding of about where you can get with what voltage, every CPU is different, but maybe it will help ya.

hmm, i noticed his increments were actually kinda bad/off...

 

sorry for this, it seems its not that great of a reference.

 

in bios find your voltage...

 

set to manual voltage

 

set voltage to v1.3

 

put your clock speed up to something like 4.5GHz

 

test for 5 mins

 

stable or crash?

 

if stable increase your core clock .1 aka 4.6

 

if crash decrease your core clock .1 aka 4.4

 

test again for 5 mins

 

stable or crash?

 

if stable increase core clock .1 aka 4.7

 

if crash decrease core clock .1 aka 4.3

 

test again for 5 mins.

 

now you do this till you find something stable, never going above v1.3, as this is the safe maximum for haswell. (is what many people will say.)

 

If  you are having problems with temps you can do a lower voltage.

 

going down bit by increments of .025

 

so if your temps are too high go down to v1.275

 

still to high? go down to v1.250

 

so on and so forth...

 

You are trying to balance your temps to an appropriate level with clock speed an voltage.

 

hope this isnt confusing. let me know

[vSyNd1c4t3]

Another thing... I notice you said you put the voltage at v1.295 but then Aida64 reads it as v1.320.

 

do you have your stuff set to adaptive voltage? cause if you set it to manual, it shouldn't ever go to anything but v1.295

[Novak]

aw man thanks for all the info, i did leave it on adaptive. 

 

i just ran a test at 4.4GHz and 1.250 (read 1.280 on AIDA64) and it went over 30mins and sat on 69dg the entire time.

 

ill just leave it at 4.4GHz, considering it runs at a much lower voltage i couldn't imagine the benefits of 4.5GHz could outweigh the effort and tax on the CPU nor time to get it right. 

 

 

thanks everyone for their responses, ill say this myth has been busted

Awesome, sounds like you found a good spot. Under v1.3 and good temps.

 

Adaptive voltage can be quite funny when trying to find your optimal clock speed, as it will change based on what clock you put in.

 

My 4790k for example will run 4.7GHz at v1.262 adaptive, regardless of if it set the voltage as v1.220, v1.250, or v1.260, it bumps itself up to v1.262 if i am running any of the following clock speeds. 4.4, 4.5, 4.6, or 4.7. but if i bump my clock speed to 4.8GHz the adaptive voltage will force it to v1.325. so since it only goes up to v1.262 when I use 4.7GHz I decided that to be my clock speed. ran the tests and its stable.
