Kernel memory leaking on Intel processors

noctua is the best :> running my nh-d14 from almost 10 years and so far no issues at all

How is the fix going to be released? What do I have to do in order to get it?

Can I choose not to?

I uninstalled the Windows 10 patch (for the first time ever I done this), simply because my Asus AI Suite III stopped working, which not only controls my overclocking, but also my fan speeds and monitors that of the water pump. I just don't feel safe running without this.

I used the Microsoft "Show or Hide Updates" tool to hide the patch from being installed, and so far it's working.

You should be able to easily control your overclocking and fan speeds in the bios, however probably not monitor the water pump.

Try this: (only Ai-Suite-3, not 2)

:thumbup:

Glad it helped ;)

Got the first update for my Win7 rig today. Not amused with results - comparing in Nevada cold start and takeoff missions for Mustang and Spit, I lost between 10 and 15 fps in both pit and external views. It will be probably worse with other units nearby - when looking left in Spit cold start mission (there's a second stationary Spit standing there), I lost 25-28 fps. Your mileage may vary :D.

If that's what this first, supposedly less resource hungry update yields, then I wonder what the second, Anti-Spectre one will bring.

If you lost such a high amount of performance was because you were very close to a cpu bottleneck. Specially in Nevada. Strange, since you have a nice overclock, maybe checking that it is funcionting correctly could help :)

We'll see :(

We have to redefine the era.

The era BEFORE Meltdown and Spectre & The era AFTER, when all new CPU's got fixed.

Nvidia will buy Intel in less than 3 years, this is my bet ! Intel will go down down down now, every day 1 step down the ladder, for many many days to come. I already have calls for AMD transitions, new Server plans went on Hold, Move-to-cloud got stopped...etcetcetc.

This really stirrs up the WHOLE IT world. You just cannot buy Intel now, you cannot.

blame bitcoin.

stealing those and other such currency is the only thing funding all this.

why for 13 years it really hasn't mattered.

now CPU need to be more secure than banks...

time locked doors etc...

Microsoft needs to add it to game mode..

when game mode is on the cpu runs less secure. because its a gaming PC and not a bank.

I dont see what crypto has to do with all this in 1st grade.

Sure, having a wallet with 150 BTC on an Intel machine now would make me nervous. Good move would be to move them to a Rasberry Pi, those are secure by design, just slow.

Forget security, this is an illusion you will always chase. De facto, with BILLIONS of circuits, which human mind shall oversee all the dependencies. 100% impossible, as just shown.

Take a paper wallet, a piece of paper and a pen, period ;)

From Softpedia news

Terry Myerson, Executive Vice President, Windows and Devices Group, explains in a lengthy post today that the impact systems are experiencing becomes more noticeable the older they get. This means that if your PC has the latest-generation silicon and runs on Windows 10, there’s a good chance you won’t notice anything different on a machine running the Meltdown and Spectre updates.

 

“These percentages are reflected in milliseconds,” Terry Myerson explained. Windows 10 devices with Skylake, Kaby Lake or newer CPUs are the least affected by the slowdowns, and the Microsoft exec says benchmarks showed only single-digit performance impacts.

 

Systems running Windows 10 on processors like Haswell and even older might experience “more significant slowdowns,” Myerson confirms, “and we expect that some users will notice a decrease in system performance.”

 

Noticeable slowdowns on Windows 7

Things are getting worse in the case of Windows 7 and Windows 8 on 2015-era CPUs, where the slowdowns caused by Meltdown and Spectre patches are the most noticeable, Microsoft says.

 

The same thing happens on Windows Server on pretty much any processors, and Myerson recommends IT admins to think twice before installing the patches. While it’s a bit surprising to hear Microsoft recommending against software updates, delaying deployment is less critical on Windows Server if these systems aren’t used for browsing or activities that could expose data to attacks, such as opening links facilitating exploits.

 

“Windows Server on any silicon, especially in any IO-intensive application, shows a more significant performance impact when you enable the mitigations to isolate untrusted code within a Windows Server instance,” Myerson explained.

 

As for why older versions of Windows and previous-generation processors are impacted by more significant slowdowns, Microsoft says they “have more user-kernel transitions because of legacy design decisions, such as all font rendering taking place in the kernel.” Detailed benchmarks will be published in the coming weeks to further analyze the slowdowns, Myerson promises.

 

“We’re also committed to being as transparent and factual as possible to help our customers make the best possible decisions for their devices and the systems that run organizations around the world,” the Microsoft executive concluded.

I wonder how it will be for gaming servers ?

Intel is too big to NVIDIA to swallow even if they get hit hard in sales this year. But glad you mentioned it because there is a 3rd contender that might be small enough for them to buy and build CPU's from. VIA. This company has X86 licencing (they bought Cyrix back in late 90's) and they have been ramping up R&D to get back in CPU business.

Cyrix... that is a name I have not heard in a long time.

Also, AMD users beware: there is a bug with the MS patch...

https://www.engadget.com/2018/01/09/microsoft-halts-meltdown-spectre-amd-patches/

So, before I start this is all a pretty new thing and I am not yet sure if it is going to impact us DCS players.... it seems, so far, that gamers aren't going to be directly impacted but the benchmarks and information is limited since it is so early (talk of performance hits range from 5-35%). It seems the more a program makes "system calls" the more the potential impact could be.

Need to point out why this is very serious security flaw.

The kernel means the operating system, the whole operating system when it is the monolithic kernel.

The "system call" is a operating system call, a transfer where a normal user space program calls the operating system in kernel space (in monolithic design, as in server-client architecture part of the OS are in user space) and that is the critical part.

The operating system is the "gatekeeper" between hardware and other software. Its task is to manage resources (hardware) and give access and time to them to other software. And the operating system is as well isolating every other software so that they don't get access to other software unless they are designed to make the connection.

This is not just a performance hit, this is serious security flaw as once you penetrate the operating system security layers, you get access to everything that any other software is doing.

And when this kind security flaw is in the hardware level, it is very difficult to really fix if you can't just "stop using" the hardware.

And if the part of the hardware is required to be used, then all things goes even more horribly difficult.

We have to redefine the era.

I don't know. They survived the FDIV bug and that was an actual recall. Everyone thought they were stupid for coming out with SX/DX line and they did well. And this too will blow over. So much so that I bought INTC, we'll see how that pans out.

We live in a world where EVERY tech is paying the price of state sponsored cyber terrorism and big $$$$/criminals in cyber attacks in general. It's the new Fulton Fish market, the new triad, the new Zettas, the new Las Vegas etc.

It'll be an interesting ride, 2018 and beyond. As I anxiously count off 9 more days! :joystick::D

I have seen Spectre at work, it is amazing, it is fearsome, it is such that I wanna open my window and throw this rig out !

Every damn hacker wants to get behind it now, and be the first to rob AT&T, VW and Bank of Brazil all same time. Then empty a few BTC accounts, it's so easy, why not, and then maybe fool Steam and messupo their DB, happy gaming... Like that.

We have not yet seen ANY attack based on those vectors, they will come, grab a beer and lean back, secure your stuff and watch. This has not even started yet, we read the welcome pages and who are the actors, the show has yet to start.

Lots, lots of AMD builds soon, hehe

from [H]:

In general, our experience is that Variant 1 and Variant 3 mitigations have minimal performance impact, while Variant 2 remediation, including OS and microcode, has a performance impact.

Here is the summary of what we have found so far:

* With Windows 10 on newer silicon (2016-era PCs with Skylake, Kabylake or newer CPU), benchmarks show single-digit slowdowns, but we don’t expect most users to notice a change because these percentages are reflected in milliseconds.

* With Windows 10 on older silicon (2015-era PCs with Haswell or older CPU), some benchmarks show more significant slowdowns, and we expect that some users will notice a decrease in system performance.

* With Windows 8 and Windows 7 on older silicon (2015-era PCs with Haswell or older CPU), we expect most users to notice a decrease in system performance.

* Windows Server on any silicon, especially in any IO-intensive application, shows a more significant performance impact when you enable the mitigations to isolate untrusted code within a Windows Server instance. This is why you want to be careful to evaluate the risk of untrusted code for each Windows Server instance, and balance the security versus performance tradeoff for your environment.

goes to show you, that "Intel Performance" Gap was too good to be true...

no one, not 1 person, would have thought that AMD would be up top so quick, so firm, so undisputed,...18 month ago

even after ryzen launch, no one thought this shift could happen.

IT IS HAPPENING WHILE I TYPE :megalol:

nVidia GPUs are also Affected by Meltdown and Variant 2, but Safe from Spectre

I havent gotten any patch yet from windows 10. Is that normal?

Do I need to do something?

Its the driver code .. that runs on the CPU that is at issue is it not ?

I think your CPU is not fixed yet. Have a bunch of machines, 1st.i7's and 2nd gen. Xeons, no patches yet.

You may can DL it directly, google the fix/Cpu
