Intel Skylake CPU flaw is making systems crash under heavy load.

GoodBytes

Intel confirms an architecture flaw in the Skylake CPU design currently sold on the market which makes the system crash under certain computationally-intensive operations.

This is not the first time that Intel shipped a product that has discovered a flaw in its design after the product was produced. It happened back with the early Pentium days, where due to FDIV issue, the CPU would at time return a wrong float point number, costing the company, at the time, $475 million U.S for the recall.

However, for the Skylake issue, Intel won't be issuing a recall. Intel says:

This issue only occurs under certain complex workload conditions, like those that may be encountered when running applications like Prime95. In those cases, the processor may hang or cause unpredictable system behavior. Intel has identified and released a fix and is working with external business partners to get the fix deployed through BIOS.

Intel says that they have found a fix, hence the lack of need to do a recall, and will be working with OEM manufacture to apply the fix in their BIOS.

Intel is not mentioning what the fix is. We don't know if it will throttle the CPU in some way, or if they play with the voltage (can 'cause issues for overclockers), or some other workaround that can potentially affect users in some ways.

There is also no word if Intel will fix the issue in future manufacture revisions of the chip, or remain with the issue, as a fix exists.

Did you experience stability issues under load with your Skylake CPU?

Why did I know something like this would happen before it was even brought out?

Well, if it's something a bios update can fix I guess no harm done.

 

What I'm interested in is whether they'll take this opportunity to axe overclocking on locked cpus... :rolleyes:

Don't ask to ask, just ask... please 🤨

Glorious AMD master race.  /s

 

So glad I went with a 4790k over Skylake.  I like multitasking, but hopefully they fix this issue.

this has nothing to do with multitasking

skylake CPUs can multitask perfectly fine

prime 95 is just an example, there may be legitimate reasons to put a cpu under that kind of load.

Hmm well prime 95 is something you shouldn't be using on intel cpus anyways. And no I havn't had any issues besides needing my bios updated due to BSODs.

Wouldn't that put it under heavy load faster?  

 

it's not just any heavy load, it needs to be doing some specific type of operations. And normal (even intensive) multitasking won't stress your cpu much to be honest.

Well we don't know the side affects of the CPU. What if performance is reduced? What if you can no longer overclock your CPU as it used to be able to?

NOTHING puts a CPU under the kind of load that prime95 does

that's what stupid about it

This isnt about all heavy loads

 

This is specifically about a complex type of unnatural load such as the one Pime95 does, which nothing else in the world is similar to

There may be the basics for a false advertisement lawsuit in that case, but good luck seeing it through in a reasonable time :P

Not the first time Intel has derped. In Haswell and Broadwell, they had to deactivate features: http://linustechtips.com/main/topic/197257-bug-found-in-haswellbroadwell-cpus-microcode-update-to-disable-feature/

 

And this on an overpriced CPU? I cannot wait for Zen to come. We need competition, not just for pricing, but also for products to actually work.

Watching Intel have competition is like watching a headless chicken trying to get out of a mine field

maybe medical applications?

mining, folding, computing, none of those are even close to prime95

 

there something about the way that prime 95 stresses the CPU to purposefully make it work past the limit, which regular programs cannot do

i dont know exactly what it is since the last time i read about it was a page long explanation, but essentially no regular program will ever do the same to your CPU as prime95 will

 

And medical applications probably use xeons anyway, which only get upgraded like once every decade :P

ARE YOU MOTHERFUDGING KIDDING ME, i've had this issue with my 6600k since august and only know they acknowledge it fortunately mine was fixed with a new motherboard, but for fudge sake they could have said months back when people could have returned their CPUs without needing a warranty replacement, intel should reimburse people who've spent months trying to figure out why skylake systems crash, like i'm super pissed that it's taken this long for intel to take their fingers out of their arses.

Then you probably aren't using Prime95 or whatever causes this as well.

 

I don't use P95. It's unsafe on any architecture.

"This is not the first time it happens". And then bring up some ancient fucking story from the pentium Era. 

 

And i'm guessing it's with the AVX2 prime95. 

 

And I vote for a tempban on anyone in this topic coining some ####-gate. It's not even remotely funny anymore, meme-o-philliacs.

Prime95 is an example of a program that will cause the issue.

If you do simulation, or any sort of demanding calculation, or you run a game 4-5 years on your computer and your CPU struggled with the game demand (and falls under the certain conditions that causes the issues), then that is not very fun.
