Is this a good temp and voltage?

Before anyone responds, don't forget, this is not a P67 or Z68 system with four cores. We're talking about a much more power intensive and hot platform. Based on the 3960X CPU (all new six-core) systems require more voltage than the standard P67/Z68 counter parts. They will also run a lot warmer. In addition, due to the extra cores, it is more difficult to get stable at higher speeds without increasing CPU voltage and heat as a trade off. Doing 4.6GHz on a 990X would be very, very difficult, but, it can be done with the X79 chipset.
 
Anyways, in regards to temps and voltages, you are in acceptable ranges, if you would like, you can fine-tune the overclock higher by lowering the voltage on the CPU and seeing if your system is stable, or pushing your CPU faster with a extra bump on the CPU multiplier, however, please note, your voltage regulators will get extremely hot, and they can burn out and kill the board if your system is pushed too high.

As long as temps are under 85c its fine, but at your vcore (1.48) you can expect to fry that cpu wihin a year and a half, and if you have teh DS 3 year warranty (1 year parts) then you have to pay for it.

I disagree, you will not fry the CPU at 1.48v. We would never configure a system that would do that after that time frame. From our experience from testing so many systems, and from actual people that work with overclocking CPUs, even 1.5v is fine for a long time as long as the CPU is cooled properly. Don't forget, this is a 6 core CPU, not a 4 core. You're spreading that voltage to six units.

Alex with all due respect everybody in the oc communites knows that

1. heat is not the killer of cpu , voltage is

2. you can cool down the heat from cpu all you want the high voltage will kill the cpu within a year with 24/7 use.

3. I know its a six core I have a six core myself if you remember justin already explained why and how higher voltage then 4.6 will kill a cpu fairly quickly.

if DS does not think the cpu will get fried then give people a 5 year part warranty on the cpu with that voltage.

Thanks for looking, well 1.5v killed my last cpu so fast . It would do 5.0GHz on 1.4v . So i will give 1.4v max a try with my intel CPU replacement.



I can pull quotes like that all day long from different oc forums and ocers.

If you don't want to take mine, justin's, dragoon's, rice's and everybody else's word.

I would love to see a cpu at 1.48 vcore under 24/7 load not fry within a year and half, that will be an oc community first, for those of use like the people I names that have fried cpus with high voltage and know first hand what high voltage can do even tho temps are under 85c its hard to agree that high vcore won't hurt, cause we know it can, otherwise everybody in the oc community would be rocking 5.0GHz oc with vcore of 1.48/1.5, but we know if we do our cpu will be fried.

there is not one knowledgeable ocer/benchmarker on this forum that will agree with your statement that a high vcore will not fry the cpu that quick.

I'm not going to get in a debate over this. 1.48v is not going to kill a CPU, nor is 1.5v. On certain occasions, if not done properly, a CPU can get killed, but, a large portion of it is due to other factors that sometimes don't get considered.
 
You can't make that statement saying 1.48v is going to kill a CPU after 1-2 years.

Alex everybody in the oc communities will tell you 1.48 will kill a cpu within a year and half, 95% of the time it will hapen, the other 5% will happen little bit after that.

as I mentioned as A customer if DS wants me to feel comfortable at high vcore like that then they can give me a warranty longer then a year on the oc/cpu.

As for me, I'm gonna say what I know to be the facts, and from all my experiences and all the oc forums around, all have shown that high vcore will kill a cpu.

If you like I can post quote after quote from members of oc forum and everybody can go and check with them by their user name on different oc forums.

Yes, but, every different type of CPU has variables. For example, Sandy Bridge is more sensitive to voltages than Sandy Bridge-E.

Here's an example of what I mean, you will see that you need more voltage for Sandy Bridge-E for overclocks: http://www.xtremesystems.org/forums/showthread.php?277928-Sandy-Bridge-E-Overclocking-Guide-(Walk-through-Explanations-and-Support)
 
1.48v is not going to kill a CPU in 1.5 years.

After the holiday I am going to call Digital Storm and talk to them about turning the overclock down some. What voltage would be good for the 3960x?

1.48v is fine if you want that high overclock. If you want to lower the overclock, we can lower the voltage. You're best bet is to contact our team directly so they can help you with that.

Alex with all due respect, you have your take on it and the oc community has their take on it and everybody in the oc community agrees that the e chips do take more voltage sometimes however 1.48 vcore is very high and will kill the cpu pretty quickly under 24/7 use.

It is for this reason that benchmarkers have the highest ocs but they never keep it that high because vcore that high will kill the cpu fairly quickly.

@hotshot146, as you see in my previous post that has the quote from justin if you stay under 1.4 your cpu will out live your pc itself, between 1.42 and 1.45 its a role of dice it can be within 5 years, maybe longer maybe shorter, at 1.48 and higher you are looking at much quicker death, at 1.5 a year perhaps.

As overclockers we like to balance the oc with the stress of vcore, in short we want the highest oc with the lowest vcore possible, I often notice that users with oc from DS can lower their vcore and keep their oc with a little different settings.

If you search the forum you will find justin (whom I posted earlier) constantly showing others how to lower their vcore and up their oc from DS's settings or if you search you forum you will see rice helping people with do the same.

Tho DS does a good job of oc, there seems to be lot of room for improvement when it comes to fine tuning it, for example you will see Cerebros here with oc of 4.5 and vcore of 1.44, rice helped him have his oc of 4.5 with vcore lower then then 1.4., its a different chip and all but I'm just using it as an example where you can tweak your oc to have better settings.

Call up DS I'm sure they can help you do the same if possible, tho as Alex said your cpu does run warmer and may need more voltage, but that does not mean the stress won't kill it the same under 24/7 load.

ok I called and got the voltage down to 1.38v runnimg at 4.4GHz. One question I have is in the bios the voltage is set to 1.38v but when I use cpuz and cpuid hardware monitior they both say the voltage keeps jumping from 1.424v to 1.432v. Should I follow the bios settings or the programs?

It's always going to change depending on the load. You should be perfectly fine.

one more question. The ram voltage is set to 1.65v. The bios said the normal is 1.50v. Is 1.65v good or is it too high? The ram is 8GB of DS brand of ram.

If I'm not mistaken the 1.65 is within the limit of the ram.

My tjmax is 70, but my tempature idle is 20c... Wtf is distance to tjmax.


Okay nvm.  Tjmax will decrease as your CPU temps increase. Skyrim on ultra and temps are still at 20c and 20c idle.

In a round about way, if max temp for core is 100c, then the distance between your load temp and max temps is distance to tjmax (max temp)(Tjunction max).

if your load temp is 70c then distance to tjmax is 30c. (assuming tjmax is 100c)

to test temps you need to load the cpu then check cpu for temps.

to test temps for gpu you need to load gpus then check for temps.

games are not the best way to test cpu temps.

follow my fah guide here, it will stress both cpu and gpu and then you can check temp for whichever you are testing for (or both at the same time).

underload it's about 50C of CPU overclocked to 4.4GHZ with a 1.4V  GPU is 70C With auto fan controller of afterburner. 50 it's about 66C 65 it's chilly at 52C of afterburner fan controller of kombustor also (different if overclocked to 1000MHZ of gtx 560 ti) 65 it's about 60C to 70C at 1000MHZ.

Well no matter what, as long as your load temps are below 85c, temp-wise you are good.

is your gpu stable with that kind of oc?

Yeah, GPU is stable. I put the fan at 65 and it was about 70C on full screen.  But, I just experimented. Just threw it back to 950MHZ.

Run fah gpu client only and see if it gets to 100% on a work unit.

keep an eye out for gpu's temps using HWMonitor

I ran both cpu and gpu in stress and got 62C at 1000MHZ on gpu and 60c on CPU. I didn't use HWmonitor and didn't use the gpu only stress. Gonna do that now.

Please use hw and make sure you run them till they hit 100% otherwise the cpu/gpu (whichever you are testing) may not get the full stress of fah, each step/percent has different stress load.

This thing takes so long. I'm gonna finish it up tomorrow, got work lol Don't want to leave it on with my sister here. When I finish it up, and test goes well. Can I keep the overclock at 1000mhz if it's stable with Fah at 100%?

I'll post it up tomorrow, I'll do it in the morning.

If it gets to 100% with no errors and max temps are below 85c heck ya, but keep in mind odds are gpu will die faster then if it was not oced.

Didn't crash on a 100% workload with no other error. Temps were chilly around 50-60c. Did it over the New years. I don't want it to die faster so I'll under clock it :( I also recently brought a 200mm fan optional for my CM storm enforcer, helps out alot. :) Also trying to get a free 3DMAX with EVGA card :) Also sorry for late reply, I meant to do it that Yesterday on December.

Happy Holidays.
