So I got board today and decided to see if I can get 4GHz stable
I am currently at 3.9GHz testing at either 1.35 or 1.3625
At what Vcore would I have a noteworthy chance of frying my CPU, given safe temps (about 50C currently at most according to internal sensors)

3.7GHz stable is 1.3125 (8hrs of prime)
3.8GHz is 1.3375 (30min prime passed)
3.9GHz is either 1.35 or 1.3625

pqwoerituytruei, what you running is fine, I've run my 955 be @ 4.1 24/7 for a few years now at I believe 1.41 Cpu V. Keeps the temps in check below 62 on the cores and you should be fine. If my memory serves me correct 3.9-4.0 was where it really started needing Cpu V to get it stable. You may find that for the performance increase it may just not be worth it. As far as frying the Cpu I haven't fried mine yet and I've pushed over 1.6 into it on Air for benching around 4.7 Ghz. Though I wouldn't suggest going anywhere near that type of voltage if you want to keep your parts in tact.
 
Generally, for 24/7 usage, 1.5v is good if you can keep it cool. I've been at 4 gig @ 1.475v 24/7 for roughly 3 years now on my daily driver.
 
after 1hr 4 min prime crashed on the 1st core with my 3.9 test
temps were only at 50C
i am just looking for the stable 4GHz for fun and document the settings for it, then back off to my old 3.7 GHz speed (CPU stepping does not work at higher speeds)

are you saying the voltage increase rates gets less dramatic after 4GHz?

Thanks i will keep it below 1.5

No. They get more dramatic. So does the temp increase.
Again, generally speaking, if you can't get 4 gig stable with 1.45-1.5v or less, you never will.

Just wondering why does the OS report my clock speed at 3999.779MHz
when i was working with 3.9GHz and i added some vcore for stability i think the number went up
Currently testing 1.4V on 4GHz (27min so far, so good at 52C)
north bridge is only at 2400, going to tackle that once i get 4GHz stable
edit:
unstable at 1.4Vcore

edit: at 1.4125V now clock speed says 3,999.707 MHz

What air cooler and what were the temps (including ambient temp)

on another note does the fact that my board only has a 4pin cpu plug and not a 8pin plug make a difference?
 
My 955 runs on a Thermalright Ultra 120 Extreme, my ambient temp is usually around 70-75F depending on weather and if I have the central air conditioning on.

I don't believe it makes a difference, your board though a bit outdated is a pretty stout board and should have no problems getting that chip to do what you want, that's if the chip can do it. Your clock speed shouldn't have changed. You should post a SS of the following tabs in Cpu-Z, Cpu, Spd and memory as well as Hwmonitor under load. It will help us see better what is going on under the hood , so to speak. In addition, when you lose 1 worker you're getting close to stability so 1 or 2 notches of Cpu V will usually get you there. Have you increased the Cpu Nb voltage at all?
 
have not touched the nb voltage (set to auto), but the frequency is only set to 2400

I can't tell why the Cpu is reading 3999 because it doesn't show the multi and Fsb settings. As far as your temps 51 is good though what are the high and critical readings that it shows. Also do you still have the power saving features enabled in the BIOS?

You may want to try and set the cpu nb V manually to 1.2-1.25 it could help with stability when running the Nb Freq higher. Though it will also increase the temps so keep an eye on them.
 
If you are referring to stepping, that stops working above 3.7GHz
http://www.overclockers.com/forums/showpost.php?p=7344382&postcount=41
only thing different is the Nb frequency is on 2400
ratio is at 20
vcore is at 1.4125

high and critical are just reference notes to make it user friendly

cpu-z rounds numbers and also who really know what it sees when it poles the board for info, *** long as its in the ball park the numbers you see in all the monitors is close enough.
 
If your multiplier/ratio is at 20 and your Fsb is at 200 that is why you're reading 3999. You have it set at 4.0 and the discrepancy is just software error.

As far as what your pc is doing it is very difficult for us to determine what is going on because we can't use the tools we normally do under windows. You say your cpu v is 1.4125 but what it's doing under load is very relevant.
 
actually i don't think that was a rounding error, i think it was a cpu/Nb frequency bottlenecking it
upped that freq to 2600
now it reports it as 4000.024 MHz
still have not touched the voltage cpu/Nb it is still on auto
i also turned 'ACPI SRAT Table' off as it does not work with > 3.7GHz

When you were saying Nb voltage did you mean the CPU North bride or the other north bridge

prime crashed at 1.4v so i bumped it to 1.4125, but sensors say it is running at 1.394 - 1.406 (during prime)
i will drop it back down to 1.4 in a few hours to try it again since i changed some other stuff in my bios
 
Cpu Nb V is what it is labeled as, sometimes a bump in voltage to 1.2-1.25 helps with stability.
 
question
are you saying if i up the CPU/Nb voltage I can probably lower the Vcore to 1.4?
is there a way to know what the cpu NB voltage is when it is on auto?

i just upped the cpu Nb freq to 2600 and am currently running prime, so far so good @37min

If the lack of Cpu Nb V is the reason for failed workers yes possibly.

on Linux I have no idea, on windows HWMonitor will let you know.

I hope it works, if it doesn't I would set it back to where it was when you passed 8 hours prime and the work on the Cpu speed first. When trying to really push our chips it is easy to lose our way if trying to change to many variables at one time. What will always help is having a reference point on which we know was stable to fall back on. Take detailed notes of every change you make otherwise this could become a :bang head experience.
 
i have passed 3hrs or prime with this config (there was no fail)

Vcore 1.4125
4GHz (200*20)
cpu Nb voltage auto
cpu Nb freq 2300

and i will say that i think it made the AI more competitive in a STK, by improving there response time

These 2 failed at around the 1hr point (+/-10min):

Vcore 1.4
4GHz (200*20)
cpu Nb voltage auto
cpu Nb freq 2300

Vcore 1.4
4GHz (200*20)
cpu Nb voltage auto
cpu Nb freq 2600

if it was the CPU Nb making it fail would upping the Vcore have helped?

only making one change per test (as someone with programing experience i know better than not to)
 
Glad you found stability,

It looks like you were just lacking a bit of Cpu V, additional Cpu Nb V would only be required if you were pushing the cpu NB Frequency higher then the board "being on Auto" can supply. What I would do from here is try passing 2 hours with the Cpu Nb Freq at 2600, if it fails then you may have to set the Cpu NB V manually. As far as your Ram goes, I see in your sig you're running 12g is that 3x2g sticks? If so you may run into stability issues when trying to raise the Nb Freq because the Phenom II's IMC isn't all that strong. If you do raise the NB Freq and setting the Cpu NB V to 1.2-1.25 doesn't help with stability I would try removing 1 stick and see if it helps.
