Hey guys im having trouble overclocking i completely followed the guide and im just having issues

My Mobo- ASROCK Z68 Extreme3 Gen3
CPU is the Intel I5 2500K and its only at 1600 mhz and its should be at 3.3ghz because i put 33x multiplier

Isn't 100% stable impossible? Even if you tested for a year straight that would only be like 99.999999999999999999999999999999999999999999999999999999999999999999999999999999999999% stable right?

Point being that its all a matter of "how" much stability one needs. From personal experience, 1 hour has been plenty stable for normal usage. Most people have found that you need a 12 hour+ run to be stable for Folding.

1600Mhz is what it will be at during idle, or little CPU usage. If you start a game, or prime95 (or anything that requires some CPU action) your CPU will kick in and go up to 3.3GHz.

Ok thanks kenny - 2 more question: Do you think Custom Blend of 5 minute intervals on small FFT + 90% RAM usage is best test for Prime95? or is default blend fine? Also does Prime95 degrade your CPU if you are hitting like 80C?

Custom is always a better test, and a nicer way of getting more stability without increasing the time.

Temps do not degrade a CPU unless they exceed the TjMax (98C for SB, 105C for IB). However, since some years ago, temp guards have been built into chips. If your chip ever did hit the TjMax it would simply lower the clock and/or shutdown the CPU (computer).

The only concern with today's technology is voltage. Impossible to guard against it, as its set at run time and voltage maximums can never truly be set. Too much and you fry the chip!

Hey guys/kenny,

To start off, excellent guide. +rep

I actually have a few questions, as I am pretty new to this. I am using my sig rig.

I used your guide and it worked great. At the moment I am at 4.0 GHz @ 1.2V.The temps max at 71-78-76-72 during a Prime95 blend test for an hour. The Package temp is 79 if that means anything. I also ran IBT pm very high for 10 runs and the highest temps I got were 73-79-79-76 with a package temp of 85.

EDIT: I am now at 4.3 GHz @ 1.22V with a max temp of 74-85-84-77 on a high IBT for 10 runs.

I am not looking to absolutely max the OC capability of the chip, but do whatever is perfectly safe to do. What should my next step be? Should I increase the voltage or leave it? Should I change another value? These numbers don't seem to great, as I have seen many others getting 4.4 GHz with 1.2V and the same cooler.

I am also having some trouble with my RAM, which is in this thread:
http://www.overclock.net/t/1265910/samsung-2x4gb-asrock-z77-extreme4-help#post_17406158
That may or may not be part of the issue, if there is one. Screenshots of all of my settings may be found in that thread too (the CPU related ones might be moreso in the spoilers at the end

Last thing that I can think of now... What's the best way to test for stability? I will be gaming mostly if that makes a difference. I have IBT, Prime95, and AIDA64. If you could mention the program and all the settings that would be awesome!

Thanks in advance,
Big Al

Hi used this guide yesterday to overclock my sig rig (+rep easy clean guide:))!

just had some question i have Asus baord and these settings are diffrent there

Turbo Boost Power Limit: Manual
Short: 500
Long: 500
Long Duration: 1

Again, only a limit. No limits for overclocking; set it to max.
Additional Turbo Voltage: Auto
Core Current Limit: 300


Max Watt i can put on short and long is 255?(should i just put 255?)

Also i dont have ocre current limit
But it says Short (core)current limit:
And Long(core) Current limit

Both need to be set at 1/8 of some Amperes? left it at Auto cause i really dont know what to set these to would like help with that:)

Started like you sugested with a 0.005 Offset And Level 2.

Resulted in 1.248 vcor in cpu-z with small drops to 1.244. (Not 100% sure if these are correct on last 2 digits but like 99% sure not at home right now:P)

and i could get to 45 multiplier.

MAx temps 1 hour blend prime95:

72-74-72-69.

Tried to get higher. but stopt at 0.030 offset(resulting in 1.272 vcore) and prime would crash withing 1-2 minutes.

Should i keep going or just settle with 45 multiplier.

My ram runs at 2133 MHZ at 11-11-11-30-2n(XMP profile).

Thnx!

Awesome guide, thanks

Very excited to try this out, got my Asrock z77 extreme 4, really keen to see if I can get my i5 to 4.5GHz, I'd be over the moon
(also to show my friends what an OC'd 2500k can do, see that they refuse to oc them, even lightly, pretty pointless to have a k version imo if they not ocing)

Hi, I have my asrock Z77 4 with a 3570k pro, upgrade to the latest bios 1.20, but in part I have only the option vcore offset and not the fixed version mode, the load-line calibration cpu brings auto, 100%, 50 % and 0%

I have to change motherboard?

thanks..

Agreed.

Don't change.

100% = Level 1 - Most vCore gain.
50% = Level 3 - Average vCore gain.
0% = Level 5 - LEast vCore gain.

If you don't have fixed, then just use offset. I prefer it anyways! Saves power! thumb.gif
