theres a difference between a stress test and a torture test

you should not be torturing components

a regular stress test like aida64 or intel XTU is already enough to make sure it runs 100% stable for ANY workload

 

and the voltage is done automatically, you cant stop it

this is why intelligent people actually use the older version of prime95 to test components, not the versions after the AVX addition

That's your opinion for me I use prime95 as I'm sure if it's stable running prim95 then it's gonna be stable 24/7.

So what you're saying that setting the voltage manually in BIOS does nothing ?

I thought intelligent people didn't use prime95 ?

I think Enderman has me blocked. Someone please show that link to him-it might help educate him on Prime95 and the instruction it uses:

I'm confused is FMA an instruction set or not ?

Well its part of one-AVX.

So FMA is multiple instructions ?

Why is prime95 even used anymore, its stupid

I've found another useful way how to test max temps:

Its just 1 instruction, which is grouped together with the others that make up the AVX instruction set.

I find it laughable that people are ignoring a post in this thread posted by Raytsou which links to Tomshardware, confirming its a Prime number bug and yet everyone's still going on and on about Prime95.

 

Hey, additional source: http://www.tomshardware.com/news/skylake-prime-number-bug,30979.html

Apparently it isn't just "heavy load". It's when calculating prime numbers. It's a bug in the software and that's why it's fixed with a BIOS update.

 

As Mister Snow also tried to point this out, I foresee people ignoring this post.

 

As I can see, people just don't read on this forum, they go by their own convictions and hammer on it until everybody just gives up or the thread gets locked. :|

 

One user posted this:
http://www.tomshardware.com/news/skylake-prime-number-bug,30979.html

 

And here, I will highlight the important parts

 

 

So to elaborate, this isn't Prime95 exclusive problem it is a problem involving prime numbers and while that is certainly not a problem for the majority of regular consumers IT IS A PROBLEM for enterprises that do this kind of research and scientific calculations because this problem is not exclusive to consumer CPUs as it's affecting Skylake architecture.

 

 

They will fix it soon and everything will hopefully be back to normal operation so stop arguing if this is a problem because Prime95 is so much intensive that nothing ever is intended to run it and look at the facts. This goes for you @Enderman

I heard that the heavy workload the new cpus can't handle has something to do with prime numbers. I have no idea, I think I just read it somewhere.

Inb4 axing OC on locked CPUs

What does that have to do with anything? Overclocking on locked CPU's disables AVX, which is what is helping contribute to the crashes. If anything, overclocking non-K CPU's has actually prevented this issue from happening on those specific Skylake CPU's. 

 

Unless you are referring to intel hiding a microcode update within the bios to disable it, which again, i doubt it. Even if they do, just flash back. Like i said, the problem does not exist for overclocked non-K CPU's due to the loss of AVX when adjusting BCLK.

I was just exploring the opportunity of Intel doing so due to the enforcement of product differentiation, but you're right. Rolling back on BIOS updates might be the way to go, but it defeats the purpose of a hotfix which is fixing the AVX errors to begin with.

Honestly, I don't think non-K overclocking is having that big of an impact on K SKU's. They are still priced way higher than MSRP, which means demand is still quite high. Not to mention non-K overclocking has its fair share of caveats:

 

Loss of AVX

Loss of C-States

Loss of 75% L1 Cache performance

Loss of iGPU

Loss of Hyperthreading (If using an H series board, instead of a Z series board)

Loss of CPU thermal sensor (Have to get temps from PECI instead)

 

I would personally pay the extra cash to avoid these headaches, as would most overclockers. The only people buying non-K CPU's with the intentions of overclocking, were the people that were going to buy them in the first place. This just means extra performance for those people. If Intel did not want this to happen, they would not have unstrapped the clock gens from each other, and certainly would not have advertised it as a feature. I believe they intended to do this. I could be wrong though. If i am, then i was smart for archiving my bios updates :)

I spot incredibly cheap LN2 overclocking for Skylake chips, whaddya think?
