Another 'are these temps OK' thread

20 minutes of Prime95 should be enough to heat up ur whole case as much as a long gaming session would. So 74c max is still well in the safe limits but I would advise you not to increase the overclock further because you must have in mind that increasing the temp on the CPU means more heat from your cooler dumped in the case which means hotter components (ram mobo etc).

I have little experience with 3rd gen intel cpus, I oc'ed my friend's 3570k to 4.4ghz with 1.28v, it just couldn't do it with lower voltage. From what I understand from your last post here, SirChumpalot, you set manual voltage setting to 1.1v so I guess your voltage is stuck there and does not fluctuate with CPU load? Is the CPU multiplier ratio also stuck on the same number now?

Not too certain on this offset thing.

In the bios, there's an entry for '+' or '-'. I take it I just select '-' and then enter 0.07 as the value?

I've selected a manual voltage of 1.1v. Whilst idle temps are quite high, load temps look like they are indeed lower.

Your bios must work a bit different than mine. If you select the '-' and it asks you to enter a number then yes just put the value as 0.07.

If its stable at that then you can try dropping it even more.
 
kaynar, correct. It does fluctuate slightly, put only a little. Prime quit after a few minutes at this voltage @40x100. I can change the multiplier and bclk via asusai suite on the fly.

Going to mess around with the offset setting again.

Will report my findings in a bit, missus has me running some errands

Cheers

It fluctuates because when under load voltage levels drop. There's a setting called load line calibration which stops this. If you set the voltage to 1.1 in bios that may have gone considerably lower during prime95, always check the voltage reading in cpu-z so you know what its actually at. Using the offset is the best way as setting manual voltage will not let the voltage drop in idle.

Thanks very much. This is all information I had no clue about. The last time I was overclocking you just had one set voltage and that was it!

As soon as the kids are done watching movies I'll get back to it :)
 
One quick question, every time I boot into Windows the CPU speed is at 3900mhz. I have to manually change it in AsusAI to get 4ghz. I've tried saving the profile but it keeps reverting back to this setting every time the system restarts.

Is there any way around this? I'd prefer to do away with AsusAI completely if at all possible. Perhaps I can set it in the bios? Though I can't see a way to change the multiplier in there, just the frequency.

Thanks guys.

There should definitely be a way to adjust the multipler in bios. I think this is it http://content.hwigroup.net/images/products/xl/149539/22/asus_p8z77m_pro.jpg

Edit - that's not it. You need to take 'turbo ratio' off auto and then choose 'by all cores' and set to 40. This should be on the main 'ai tweaker' page.

Yeah, thanks. Just found it.

Does anyone else find this Asus utility a little bit... er.... pooh? The update seems to just lock the program up. I get motherboard temp errors for some reason too. Perhaps it just needs re-installing.

As a side note, I'm loving how quick Windows 8 boots up :cool:
 
OK, vcore set to 0.950 in the bios. Manually set the CPU speed to it's stock 3.5ghz (35x100).

Temps are 34, 27, 29, 31

Fan is at 500rpm or thereabouts. Will prime this and see how far it gets, I'm worried the voltage is too low!
 
OK, sorry for posting yet again. I'm trying to log this as well as perhaps get some feedback. Prime lasted 12 minutes before a hardware error was detected, I suspected as much but I have a feeling I'm close to getting this stable and it'll only need a couple of minor tweaks.

Vcore in the bios is now 0.950. Offset is 0.07. Current idle voltage in CPUZ is 0.880. Temps are nice and low, only Core#0 is slightly above 30'C.

Starting Prime. Vcore is now 1.120
 
So, had Prime running for the last hour. No errors, no warnings.

Core voltage would very briefly hit 1.12v, but for the majority of the time it was around the 1.080 mark. Max temps were as follows:

Core#0 - 66C
Core#1 - 69C
Core#2 - 66C
Core#3 - 67C

I'm happy none of them hit 70C. Even though as Kaynar said above these temps are still within the safe threshold. I'm happy that I'm getting these sort of temps with a low profile cooler. One that's not exactly known for it's cooling performance.

Questions:
- In CoreTemp, what is 'VID'?
- Where Hyperthreading is concerned, does turning it off increase performance?

Temps are now down to 32, 25, 26, 27.

Would welcome your views.
 
VID should be ignored. It's basically a reading of your stock voltage which can sometimes be really inaccurate. Some people think a lower VID = better overclocks.

I'd recommend just leaving hyperthreading on. It's the only benefit of the 3770k over the 3570k.

When you set the vcore to 0.950 was that a fixed voltage? Are you stable with 1.12v @ 4ghz or stock speed? Try lowering the offset a bit more as there's a big difference between 0.950 and 1.12v. The lower you get the temps the better and it will also lower power consumption.

No that wasn't fixed. That's on auto. Offset is .07.

Seems stable. I know an hour in Prime isn't the be all and end all but it's a good start. Watching movies and just general usage was fine after the Prime test. No glitches or artifacts. I'll test again tomorrow for longer.

Am I right in thinking that if lower the offset, the voltage won't be able to go as low as it does now? Is it 0.07 either side? or am I getting confused?

Thanks

I'm getting confused as well :D

When you say its 0.950 in bios do you mean that's the reading in the sensor page or do you have it manually set to that along with an offset of 0.07? You should only be adjusting the voltage with the offset and leave any other settings related to cpu voltage at auto.

If you use a greater '-' offset such as 0.09 then the voltage will go lower than it is now.

1.08 - 1.12v is a very nice voltage as it is though, is that stock or 4ghz? If its stock it could probably go a bit lower without losing stability.
 
It's set to that in the bios, as far as I can see it's on auto. I've only adjusted the offset voltage.

It's at 4ghz. I'm tempted to leave it there, especially if it passes a longer test tomorrow with prime.

If my requirements were different and I had a better case/cooler, I'd be more than willing to push it further. In an HTPC however, I think 4Ghz is probably more than enough. What do you think?

Yeah 4ghz is a nice overclock considering its in a small case, decent performance boost without having too much heat/power increase. I'd definitely be content with 4ghz at those voltage settings but you could always try a slightly lower voltage and see how it goes :)

I agree. I'll give it another test tomorrow and then use it for a couple of weeks, see if any issues occur. After that I'll look at dropping the voltage.

Thanks again for all your help.
 
Just a quick update.

Everything seems to be stable. No lockups or freezing. Prime has been run again for another hour. All seems OK.

One thing I've noticed though is that the voltage doesn't seem to drop after a load test. It definitely used to do this so it's as though the turbo feature has been turned off. I noticed that the CPU frequency is at a constant 4ghz.

Could it be that I've changed something in the bios inadvertently?

On this page, should Turbo mode be enabled by default?

Leave everything on that page at default and only adjust the multiplier on the main AI Tweaker page, not under cpu power management. I'm not sure what it should be at, probably best to load defaults in bios and change the multiplier/offset again.

If its still not downclocking then in windows search for 'power options'. Put the profile back to balanced (it may have changed to a custom Asus one) If this doesn't solve it click change plan settings -> change advanced power settings -> processor power management and set minimum processor state to 5 percent. You should see it at 100 which is causing it to run full speed all the time.
