I5 2500k ASUS Sabertooth P67, need help with easy OC

[baybiz85]

I am a total beginner to OCing and want to OC between 4.5ghz and 5ghz as easily as possible without any problems. I have done some OC research but still need a guiding hand.

i5 2500k
ASUS P67 Sabertooth
8gb DDR3 1600
Asetek 550LC Liquid Cooling w/ Dual Enermax fans (push pull)
EVGA GTX 560 Ti (Factory OCed to 900mhz)

Let me know if you need any further information.

Thank you in advance!

You're likely to get good info from here: Official ASUS P8P67 Series Overclocking Guide and Information. Yes, it's for the P8P67 series, but most of it will likely work for the Sabertooth.

Ok, thanks for the link!

Overclock a Core i5-2500K to 4.5GHz
1. Enter the BIOS by pressing Delete as the PC starts
2. Enter the Advanced menu by clicking the button in the top-right corner
3. Set the CPU multiplier to 45x
4. Enable Load-Line Calibration
5. Set the CPU voltage to 1.3-1.35V
6. Set the CPU PLL to 1.9V
7. Set the VCCSA to 1.1V
8. Set the VCCIO to 1.106V
9. Hit F10 to save and restart


100% stable.

Man talk about breakin it down nice and simple! Thanks bruh! These settings don't cause any additional wear and tear on the mobo or CPU right?

 

[baybiz85]

I was also looking at some OC website, those VCCSA and VCCIO voltages aren't too low?

 

[baybiz85]

What about any other settings, leave as is? Sorry for multiple posts...

 

[Deleted member 362816]

Lol overclocking is always going to cause more wear and tear. its like putting a super charger on a dodge neon its not great for it but it goes fast.


Make the changes i posted and leave it alone.

Thats a cyberpower built isnt it.

VCCSA should be 0.925v (CPU default). You don't need to raise that unless you are going to try BCLK overclocking.
VCCIO should be set at 1.05v (CPU default), as the increase isn't likely to affect the overclock at that low a speed.
CPU PLL at 1.9v may be required, but leave it at the default setting and see if it works first.

For me, none of those settings needed to be increased for me to get my 2500K to 4.8GHz.

BayBiz:
I would do steps 1-5, then skip straight to step 9. If that turns out to not be stable, then change the CPU PLL. The other voltages listed shouldn't need to be changed at all.

No I don't shop at CyberPower

Thanks I think I've heard what I needed to hear now, I just want a stable 4.5 clock while having my components last a long time still.

 

[baybiz85]

Is it true that I have to manually set my RAM to 1600 even though thats what it is suppose to be at already?

 

[Leaps-from-Shadows]

Yeah, it will default to 1333. You'll have to set it to XMP or 1600.

LFS you the man! Thanks again bro!

Heh - Im running my CPU at 1.5v (with a nice big Scythe cooler) and 5Ghz!

All CPUs ar different, you could try and gage where your CPU's 'safe' limit is. A lot of people set their voltage limit for the 1.4 - 1.45 mark, i heard that an Intel tech had posted on a forum that 1.52 was the 'safe' limit for the 2500K. Y temps rarely go over 60 degrees at 5Ghz so Im happy 😉

Asus offers great uefi software with that board, Why not use the auto ez clock in the bios. I used the setting for my P67 sabertooth/I7 2600k just to see what it would do and on auto it overclocked to 4.5ghz super stable. 34c (75f in room) on air 212 hyper +

 

[baybiz85]

I heard the auto clock can turn the voltages up higher than needed, what is yours at using the auto clock?

the middle stock setting is 1.165v which is running 3.8ghz

the higher one is 1.220v which is running about 4.6ghz

this is all done with the efi auto clocking, yes doing a manual over clock will get better results, but for someone that is new to overclocking this is some good stuff.

 

[baybiz85]

wow 1.22v at 4.6ghz is actually pretty good compared to other posts I've seen on multiple forums. You got that from the auto clock? I'm impressed.

yup from the highest auto clock in the ez bios, keep in mind this from the I72600k , but i believe the 2500k is similar

Lucky overclocker. The average for 4.5GHz is 1.3-1.35v. Must be a C-batch CPU. My B-batch 2500K certainly won't do what yours can.

 

[baybiz85]

Man hope I get a C batch 2500k haha. I'll auto clock first and see what I get I guess. If I download CPU-z and a temp reading program would that be all I need to make sure everything looks good?

 

[Leaps-from-Shadows]

The batch number is listed on the box the CPU came in. It will start with L and have an A, B, or C somewhere in it.

 

[i7ftw]

i got mine 2 weeks ago from new egg and batch # is 3049A423
