Kernel memory leaking on Intel processors

They ran into an issue with the MS patches, some PC's up to KabyLake have sudden reboots.

MS is investigating and promises a quick fix, aka revised patch.

You can deinstall the patch anytime if it occurs.

Good video describing the issue:

Happened to my machine running an Ivy Bridge core I5: random reboots while in DCS (but also within windows)

Drove me mad, the logs showed a simple kernel-power entry upon reboot, and the memory dump lead to believe it was a memory management issue.

Long story short: i ordered a new mobo and a 8600k i5; this patch was a good excuse to upgrade an old system, and it made it plausible for the wife: "Hon... pc is wrecked, look... it keeps rebooting.... i guess i need a new mobo.." :)

I repeat: "...up to Kaby Lake have sudden reboots"

There is a good chance your new setup will suffer the same issue until they fixed the fix for the flaw. What a joke.

We may throw them out of the window, honestly. If you'd run a bank, health care, power grid, nukes, CCC, all those suffer the same, either way, there is no escape.

Why did you buy a haunted Intel may I ask ? Now that the new Ryzen is on the door step !

By all means, I would return the box unopened and wait for AMD's answer on IPC questions we have asked, simply spoken.

8 series is coffee lake ;)

The fix is known, there is an MS KB you can download to avoid the issue since intel themselves asked MS and other partners to stop propagating the KB causing the issue.

Why did i go Intel Z370 ? Not too sure actually, i wouldn't have minded an AMD, i guess i'm just not used to AMD

I've always liked my i5's for gaming...

If this is of any help: (dated yesterday):

:

"Last night, Microsoft released KB 4078130, which is specifically designed to turn off the Intel-identified buggy code in the Meltdown/Spectre patches. Sayeth Microsoft:

‘Intel has reported issues with recently released microcode meant to address Spectre variant 2 (CVE 2017-5715 Branch Target Injection) – specifically Intel noted that this microcode can cause “higher than expected reboots and other unpredictable system behavior” and then noted that situations like this may result in “data loss or corruption.” Our own experience is that system instability can in some circumstances cause data loss or corruption.

While Intel tests, updates and deploys new microcode, we are making available an out of band update today, KB4078130, that specifically disables only the mitigation against CVE-2017-5715 – “Branch target injection vulnerability.” In our testing this update has been found to prevent the behavior described.

The patch is only available from the Update catalog "

basically this says, in order to fight the reboots they opened the door again.

I just pointed a potential sale to AMD, 2 new servers and 7 clients, I told my client that Intel is no option, defo NOT. AMD or wait, dont buy ANY Intel as of now.

anyway, bad time to buy a cpu

I thought AMD was not exempt of this.

 

Anyway, how the heck did you overclock with 1.175 volts??? :joystick:

My CPU falls back to it's programmed "minimum" Volt value per Hz, this is microcoded in the CPU. I can dial in 0.5v and it will still use the minimum Volts it was programmed to use, no notch below.

My peak Volts under heavy load is 1.375-1.385v, round about there. If I could lower the Volts more it would prolly still stay alive ;)

Yeah, took me a while to find out why too, it's misleading if you drop below the threshold with your CPU. Most CPU's dont do this, they will fail before you reach the lower threshold. Negative Offset can help you to get lower down, but I wait for better Bios to work it more, got tons of other higher priority things to do atm.

Double post!

And just when I couldn't wait to upgrade my ancient Q9650 system... it's not affected by Meltdown or Spectre (as far as I can tell) :D!

Re Meltdown, sounds like Intel selling us ###t over the years because they could! Hope AMD can take advantage of this and offer far more competitive single core performance to rival Intel.

Guys, I have one question.

 

Today I got the KB4056892 windows update patch but thats all I got, I never actually updated my i7 firmware and dont know what it is or how its done.

 

Can anyone explain me a little bit more about this?

 

 

Thanks a ton.

It's my understanding that Intel pulled the patch due to issues.

you do need patches for OS and new Firmware to fix it.

this is still very strange...and pretty silent now

go to grc.com and downlad and execute "inspectre.exe"

THAT tool tells you wht is going on with your rig.

also see the Intel PDF Chart thread of today.

Check the Intel PDF I linked.

Once Intel has made a microcode for your mobo it is up to Asus to make a new Bios with it.

Imho, I doubt we will see any further back than Z170.

I also runa X99 in a server, Asus X99WS/IPMI. I do not expect to get that machine fixed anytime soon , if ever.

Very sad
