Unfortunately, only at 4.75GHz (I'm using the Aura) but seems like there's headroom for more MHz's or less voltage since it looks rock solid.

Yeah, but that's LLC set to "high" with a BIOS setting of 1.45V. I have highest and extreme, don't wanna know what they will do. While doing basic stuff on the PC volts go up to 1.52V mostly.

highest is most likely like ultra high on the sabertooth, i use ultra high as i find it to be better than high....but thats just my point of view...this isnt a recommendation either lol...

just play around and see what fits you better but again 1.52 is high so you may of been given a pig of a chip mad.gif

i find ibt avx takes more voltage to get stable than any other test you use...so bear this in mind too.....i always get ibt stable and then i knock down the volts a bit....never ever had a problem with doing it like this...others may disagree but it works for me and i would never lie about stability

IBT is crazy and I don't use it. I just use BurnInTest from Passmark since that's proven enough. The difference between the draw from the socket is 100-150 watts! At 1.488V on 4.5GHz it drew 400W from my wall socket. It's never going to happen in any applications so it's really a lot. I feel more comfortable to let Burn In Test run for 20-30 minutes. So I completely understand you.

IBT got me here at first place. Now I'm trying to work with what voltages it required me to get stable on some lower frequency and I'm trying to balance the voltage and the maximum clocks I can get.

And yeah, my chip is hungry but I get around it smile.gif No point of getting another FX now. Sometimes it acts good, on a 4phase mobo it gave me 4.5GHz at 1.56V and that's a mobo not reccomended for overclocking.

My philosophy is that if you can code work for a computer - any code - any workload able to be ran by the CPU, the CPU should be stable enough to run it for a significant time.

For PCs at home, ANY program demand for HOURS.

For workstations, rendering stations, severs, ditto but for DAYS.

So as unrealistic as IBT is, I always make sure its stable at EXTREME setting for an hour or two.

there is a saying "if you can cool it you can clock it"

i know a guy @F3ERS 2 ASH3S whos been running near to 1.7volts(ithink) and hes still going to this day, just make sure you keep temps in check

Exactly

Ultra high is probably better for you

Yea. I would stop. You may have that poor of a chip but not common.

You are probably missing a setting if you can not get it stable for normal Ibt. Ibt is a weak stress test that I can pass at voltage just above being able to boot...

What is your cooling and vrm cooling?

Can we please see bios screens of every setting you changed

Just food for thought on stability

How much experience have you had with overclocking? This attitude is generally reserved for amateur overclockers who have never had corrupted data.
Quote:
A stress test is running all of your CPU cores flat out for however long you run the test, unless of course a core drops out because your overclock is unstable, I see the need for short term testing say an hour or maybe 2, because it won't take that long for an unstable overclock to show itself, but 24hrs in my opinion is not necessary.

I think you are confused. The error is not found because the CPU is at 100%. A major error, or more likely, many tiny irrecoverable errors, happen at any % of CPU usage. The programs are designed to find inconsistencies as fast as possible, utilizing all resources available to determine the stability. Its not lets see how hard we can squeeze your CPU till it breaks. Is it stressful? Sure, is the stress that causes error? No, that would be instability or heat. Another good way to test your cooling solution too I might add.

Quote:
There is not a thing on this planet designed to last forever, your precious CPU included when companies like Intel and AMD, guarantee their CPUs for 3 yr warranty time period, they're confident their CPUs will actually go past that time period, however that calculation is based on 3 yrs and beyond of normal use.

They know their CPUs are capable of lasting under normal spec'd use longer than the 3 yrs or they would not warranty them that long.

Not sure why this is even here. This has nothing to do with stability testing, unless you are assuming that all CPUs that are brand new should not be tested @ stock settings? Which a CPU should be tested to ensure its not defective. Rare, but it can happen.
Quote:
Now the cold hard fact is that overclocking your CPU will shorten its lifespan, but we accept that for the additional speed we gain, most of us will replace that cpu with an upgrade before is life expectancy arrives anyway, so taking it out of specifications is acceptable.

Has nothing to do with stability testing. Its about error prevention.
Quote:
However that's with normal day to day use, surfing the web, audio and video editing and converting, gaming, office documentation Etc, and though serious bench stress testing is necessary to achieve a stable overclock, what damage does stress testing over a 24 hr time period and beyond, actually do to shorten the lifespan of your new CPU.

Why would you even overclock then?
Quote:
For example if you stress test your new quad core CPU for 24hrs, and all 4 cores are running at 100% for 24 hrs, how much normal daily processing is lost, because no daily application uses all 4 cores at 100% for 24hrs, so at least think about that when you overclock your CPU, and use at least some kind of wisdom in your stress testing.

Again its not the stress that creates the error, its stress that finds the error. Errors can occur with as little as 1% core usage. The alternative is to use your computer until one day, your boot sector is corrupted, and Windows 7 repair, can't fix the files as the damage has occurred widespread through your file-system. At this point you are even lucky to recover data off the hard drive. Assuming you are still not using an unstable overclock, recovering data, will most likely keep it corrupt/re-corrupt it.
Quote:
Because if you don't think you're adding to shortening the life of your CPU, you're wrong!

Stress testing your CPU, if its adequately cooled, is not shortening your hardwares life, its the extra voltage/clock cycles from the overclock if anything. It sounds like you have a ton still to learn / grasp and thats okay. Overclocking has many useful applications, such as a technical server upgrade, gaming, scientific calculations, protein folding, etc. Many of those demand stability for personal and professional reasons. Folding requires 100% accurate data, or its wasteful time for both the user and server, which anyday can provide a cure to cancer (hopefully.) A non tested overclock in that field is extremely frowned upon by many people who dedicate entire machines to just folding.

I am not saying you have to stress test your CPU, or it will die and kill everything in your computer, but you are not going to convince anyone who knows what they are doing that its a waste of time.

I don't get why people are ever against having a fully stable system? It takes about a day if you actually have good settings. Maybe apathy or general laziness, but still, it will create so many headaches in the long run trying to figure out why the computer just doesn't want to work today.

There is no such thing as " a more realistic every day load" or my personal favorite " prime pushes too hard and I will never in real use do that ".....
It is staying to carry over (that attitude) from intels as they can not oc that high without being unstable. Or to much heat load esp with avx2 instructions

That said this is not a one to anyone. If you want to not be stable don't. However just don't run around stating you are stable.


The only unrealistic thing is heat load that they produce but really it isn't unrealistic.... I have seen games do my max temps before

Ah, i see. I thought it had some stability test incorporated. Very instructive post and i will also re-post another post from Raging Cane, which i always keep in my oc.net links:

I never actually watched the draw from the wall before and found it to be all over the place in IBT. It varied from 380 to 500 watts.

It sounds like you are not using LLC at all. What Is see in my GD80 is that the board will show higher voltages at lower loads and lower voltages at higher loads so only what it is doing at 100% loads is important. This is to compensate for vdroop.

Less LLC in the Sabertooth means more vdroop so more static voltage is needed to cover the vdroop. Higher LLC means less or no vdroop so lower static voltages are needed. Also higher LLC adds more heat. My compromise is a little vdroop and less heat. So experiment but really only pay attention to 100% loads.

I have two 8370s. One went straight to 5 for me and the other is good for 4.8-4.9 or so. Maybe. I never bothered to find out.

It sounds like you are not using LLC at all. What Is see in my GD80 is that the board will show higher voltages at lower loads and lower voltages at higher loads so only what it is doing at 100% loads is important. This is to compensate for vdroop.

Less LLC in the Sabertooth means more vdroop so more static voltage is needed to cover the vdroop. Higher LLC means less or no vdroop so lower static voltages are needed. Also higher LLC adds more heat. My compromise is a little vdroop and less heat. So experiment but really only pay attention to 100% loads.

I have two 8370s. One went straight to 5 for me and the other is good for 4.8-4.9 or so. Maybe. I never bothered to find out.

Thanks man.

I get all your words, but I just feel IBT is too much. Really hard to get it stable and requires much more voltage than Burn In Test I was using. One hour of CPU and RAM stress testing usually did the job - even though it's not as fast as IBT but while using a 630W PSU and a OC'd 8320 with a GTX970, it wouldn't be normal for the CPU to pull 500W and the GPU to pull 200W since I'd get over the max current the PSU can give. IBT is really weird and stresses much more than needed I think. Never had an issue with a burn in test stable system.

Anyway, are you saying that LLC should just keep a constant voltage and not up it under load? Since I was using it to up my voltage under full load to maintain stability, like from 1.52 to 1.56.

And I'm thinking of swapping my 8320 for a 8320E or 8370E since I'm needing 1.560V now for stability on 4.7GHz, on Aura. Used to be 1.47V or 1.50V on Sabertooth as I remember.

first - stability is subjective, do what you want. but most clubs have a minimum requirement - aka - you will be asked for proof of stability and you may not meet that, which again is fine, if you dont want to or dont feel the need to, who are we to tell you you are wrong.

second, if you are only using ibt ( regular non avx version) why waste the energy ? just set it and if it boots run it. ibt is all of but useless and will not show instability.

i understand ibt used to work fine, but cpus have progressed far since it was released and it does not even make most break a sweat- thats why your avx uses more voltage to be stable- they are actually working now
