Auto OC Asus

[cameronh779]

Hey everyone. I have been wanting to squeeze a little bit more performance out of my CPU for a while. So i went ahead and tried the auto OC in the BIOS. My computer restarted twice (i was thinking it would be a process with trying diff things) but as soon as I hit ''OK'' it restarted twice. Now its @ 4.3Ghz and voltage goes to about 1.280 and flucuates a little. Temps are about 60-64 after running Prime95 for the past 30 minutes.

I mean should I trust that this is a safe OC? I know i could run prime95 for 24 hours for 100% stability check but I mean if i can leave it like this and let Asus do the work that would be fine. The only thing is it seems like a high OC and low voltage. But I dont know much.

<--- System Specs.

EDIT: Voltage has gone up to 1.312 on CPU-Z. Hardware monitor says 1.361 as current. Bouncing some, min/max is 1.346/1.366.

Also, id like to get max life out of my CPU, so if this is gonna to decrease the life of it possibly by a large amount id rather do a simpler overclock with the forums help that wont decrease the life as much. I mostly just play World of Warcraft and some other games so my computer doesn't run @ 100% often im not guessing.

EDIT 2: If I can get a decent performance increase to say 4Ghz under stock voltage that would be great. I just want a little more out of it without decreasing the life of it. Im planning on having this system for a few more years at the very least.

perfect.

Just play your games ( or whatever you do)

The voltage may be high for the clockspeed (auto tends to do that), but the voltage itself isn't high for the CPU. We say to keep that under 1.45V if you want to keep it a few years. So, as CAPS said, you are fine. If anything, you can now test to LOWER the voltage, and/or push thet overclock higher. These push past 4.5Ghz without even flinching... here is a good beginner's guide: http://www.overclockers.com/forums/...Beginners-How-to-set-your-25-6-700K-to-4-5Ghz

Id trust CPUz voltage personally... that program can't tell VID from Vcore from a hole in the ground at times (in other words, its not consistently correct). Id take those voltages and set the manually in the BIOS...

Thanks both of you. I think ill leave it where it is for now. And come back to that guide and back to here if I ever want to push it. There are alotof different settings and I really just wanted a simple overclock for a little more performance.

I do have a question.. say the OC fails in any way it can like say, BSOD, ''Overclock failed'' from BIOS on restart. If any of that happens will Asus auto tweak it again? Or will I need to then go in and work on finding an overclock myself?

EDIT: Also I really need to be sure that this chip can last the next say 4-5 years @ this level. If not id rather revert to stop w/ speedboost or w/e. I am taking care of a family member and do not have money to replace anything for a while and if something happens im screwed.

 

[EarthDog]

I dont think it will correct itself... you need to adjust it manually. Auto really isn't that good at settings things which is why most (who are in the know) recommend manually overclocking. Really, with your CPU, its simply multiplier and voltage. over 4.7Ghz, maybe PLL Override Voltage enabled, that's it. You have plenty of headroom left. I would still manually lower the voltage. The goal of any overclock is to be at a clockspeed with the least amount of voltage needed for stability.

Can you give me a quick summary on how to do this? I know there is a probably a guide but id rather it come from someone who already knows the situation and my hardware. I'd appreciate it.

 

[EarthDog]

The guide walks you through it pretty well.. I can't hit F10 for ya.

Look through it... try it! If you have trouble or questions, then ask.. but at least try first!

Sure thing. So just to recap, I keep the auto clock on and all im aiming for based on what I want is to find the lowest manual voltage for my clock with the auto tuner?

EDIT: Anything i need to disable or anything? Im reading the guide but im assuming for now all im needing to do is tweak voltage.

 

[cameronh779]

I have it @ 1.27 atm. Since the guide said its possible but rare that some chips can do 4.5 with 1.27 id figure for 4.3-4.4Ghz 1.27 should be okay. So, im running Prime95 now.

With 1.300v you should get 4,5Ghz stable and maybe even more. But 1.300v and Multi at 43 would be a good starting point.

The asus p8p67 is a great board, I still regret it I destroyed mine with a bios flash that went bad. These boards need optimized defaults first, then you have to check your drives booting order and if ahci is enabled etc etc. All auto settings are already good with this board.
Auto overclocking is a nice feature but gives too much voltage, which makes things much hotter than needed.
I have the cpu fan set in bios to go 100% when over 50°C. You do this by setting cpu upper temperature and cpu fan max duty cycle. Adjusting case fans make things quieter, but also increase heat, and with my current fan profiles it's not that noisy anyways. So my case fans are always at 100%.

In AI tweaker set :
AI overclock tuner manual
Turbo ratio by all cores
By all cores (can adjust in os) set at 43 for starters
Memory frequency at whats printed on your ram.
Dram timing control/primary timings at whats printed on your ram sticks
cpu voltage manual, then set 1.300v for a starting point
Dram voltage as printed on your ram sticks.

Most likely you will be stable with multiplier at 45 and 1.300v (or even less voltage) but you will have to find this out by yourself. After that you can experiment with offset voltage (which is the other option for cpu voltage). I need +0.025 to have around 1.300v when I actually stress my cpu in windows. Could be different on your setup though, so again, you have to find that by testing and testing.

ps. the p8p67 boards had some ram issues back in the days, some xmp profiles weren't read correctly etc. So setting ram manual fixed that. I did this on that board and my current one, and never had a ram problem. But you could simply enable the xmp profile which should set your ram correctly.

no.. you need to adjust the multiplier manually.

 

[cameronh779]

no.. you need to adjust the multiplier manually.

I mean just for the basic auto overclock. I think 1.27 is going to be stable. The multi is @ 42 and bus speed is just over 100. Like 102.3. Either way its just above 4.3Ghz. I really didnt want to mess with all this at this point in time I just wanted to have a simple auto overclock. Which I got, once i asked if it was safe.

Now I assumed that with that overclock finding the lowest stable voltage for maximum longevity was all I needed to do at this point in time.

Im assuming you are talking about when I decide to overclock and push the chip in the future? If the 4.3xxGhz is stable at the 1.27 (which I will find out in a few hours) id like to keep it there for now and then when able to have a day to sit down and fiddle, then start manually adjusting more things and try to push for 4.7 or whatever I can get with a lower voltage.

I was assuming that I was just adjusting the voltage manually to get more longevity out of my chip since the Auto Oc may have put more power into it than needed. Which if stable is what ive done.

 

[Flow]

?
The basic auto settings (including turbo) wouln't need much more than 1.20. By default it would be something like 1.225v on that board. It did this for my 2600k at auto settings.
And it ran stable at much less than that.

I think you're confusing some bios settings. Your cpu has a base clock of 3.3Ghz and a boost clock of 3.7Ghz.
Boost enables when you stress the cpu. Thus it will read 3.7Ghz in cpuz when prime is running.
It will clock down if you end prime.
Your voltage will sit around 1.000v when idle, and ramp up to around 1.225v when you stress the cpu, thus enable the turbo boost on all cores. All on auto settings ofcourse.

 

[cameronh779]

I decided to just set things manually.. I turn the bus speed down from 102.3 to a 100. Then put the multi at 44 rather than 45 so i can try to run @ 1.27 for now. I turned speedstep off and thats it. F10.

@Flow According to the guide that was linked it is very rare that these chips get 4.5Ghz @ 1.27 volts. My auto OC is in the picture up top which is @ about 4.35Ghz. So fairly close, I figured if the rarity of 1.27 with 4.5 then it should be more common to run fine with a 43 or 44 multi. So i went with that to start with.

I really didnt expect to get this involved. I guess I may try to lower the volts in the future but if this is stable @ 4.4Ghz and 1.27 volts. Im gonna keep it there if thats a decent recommendation.

 

[Flow]

Haha, yeah it can be a little underwhelming.
But 1.27@4.4Ghz is good.

Anyway, many 2500k and 2600k chips did 4,5Ghz easy with 1.30 in the first 1,5 year. After that there were some that needed much more voltage yes.
But the general consensus was that you could run a 2500k at 4.4 or 4.5 GHz out of the box, with the proper voltage ofcourse.
Seeing that you could be stable at 1.27@4.4Ghz, makes me think 1.30 should do 4.5 also.
But the auto oc just isn't worth it, too much voltage and too much heat.

 

[cameronh779]

Is speedstep what lowers the power consuption and speed when idle? What setting is that? Because I really like that to stay on if it can. I have my computer on 24/7. Typically if im not on it it has just VLC running.

 

[Flow]

Yes you need speedstep enabled. You also need offset to have low voltage when idle or doing simple tasks.

But first you need to find the proper voltage for your overclock. Then you can experiment with offset values to get to that voltage number.

So, if this is stable. Then i can enable speedstep? Would I need to check again for stability?

I'm gonna let Prime95, run for about 5 hours. After that ill consider it stable. Then enable speedstep. If it isnt stable ill go to 1.3 and try again.

Also if it is stable maybe one day ill push for something more. Right now im hoping this is stable and I can move on with my decent increase. And I can work on my GPU, which im much more familiar with OCing.

3 hours would be sufficient but 5 hours is ok also.

For your voltage to clock down when idle you need speedstep and offset voltage.

Offset voltage comes in plus and minus values, or + and -.
The values are starting with 0.005.

Here's the thing with offset values, you have a default voltage coming from your psu running through your motherboard, this could be something like I already mentioned. 1.225v when stressed on the cpu.
So the +0.005 would be the same.
Adding to it like +0.010 would make your voltage when stressed 1.240volt, +0.015 would then be 1.260volt and +0.020 would become 1.280volt. Well, something like that.
So you need to know first what voltage you get with +0.005.
If it's way more than your curren 1.270volt, you need to use minus values or -0.005 etc etc.

When you've found the correct value that gives you 1.270volt in windows when stressed, you will find that your voltage goes up and down depending on current demand. Or in short it will sit around 0.984v like mine while I'm typing this.

There is one other thing we haven't talked about yet though, vdroop. Could be your voltage now fluctuates between 1.27 and 1.26. This could mean instability at unsuspected moments.
You can solve this by using slightly more voltage or increase the offset value with another 0.005 or even 0.010.
Or you can set cpu current capability at 110% or even more, this setting reduced my vdroop significantly.

But simply, im just asking, once this has ran and is stable... I can turn speedstep on. And continue doing things with my computer? Forever.. unless at some point I decide I want to push it more.

But for now, I just want to know that if this is stable, all i need to do is enable speedstep. Then I can be done.

 

[Flow]

Well you know, speedstep alone wont make your voltage go up and down. Not with manual voltage which fixes it at the value you set.

But yes, if you want to run it at 4.4Ghz@1.270v 24/7, then you should be done with it.

Thats all I needed.

And just for knowledge purposes.. are you saying the offset voltages is what makes the CPU voltages bounce up and down and setting the offset manually prevents that? Is that the purpose? Try to explain in simpler ways like that for me if you can.

 

[Flow]

Yes it is.

To put it very simple, I set for voltage offset, offset sign "plus" or "+" and offset voltage in the box 0.025

This will give me a cpuz reading of 1.300v when running prime95 and 0.984v when doing nothing.
Don't mind the picture showing 0.020. and don't mind the cpu voltage showing either, it's bios voltage from that moment. Not what windows shows.

 

[cameronh779]

So can you explain the point of offset voltage? Is that like an ''addon'' to speedstep, so that even running @ 100% load it will lower or raise a little bit based on the + or - and the value you have set? Allowing the voltage to have ''breathing room'' rather than a 100% set value. Example if your clock needs just a tad more voltage it can with the offset otherwise it may fail?

 

[Flow]

You have to look at it differently.
With auto settings speedstep and offset will be enabled and not adjustable.
It's when you start using manual settings when they become adjustable.

In short, they work together.

As for the rest of your question, you need XXX value for an YYY overclock. Giving a tiny bit more wont hurt. But having a tiny bit too little could crash your game.
So if your 1.27@4.4Ghz appears to crash after 4 hours of prime95, chances are you need 1.28v.
And if that also crashes after 4 or 5 hours of prime95, then you need 1.29v

After you found what you exactly need, you can fiddle with offset and choose the + or - value that brings your system to that exact voltage when running prime95.

It's really simple, if you want your clocks and voltages to trim down when you're reading some forum post, and go up when you fire up your fav game, you need offset and speedstep.
