Posted By: Londo
Subject: KB3064209 breaks the G3258
Date Posted: 20 Jul 2015 at 2:22am
I use a G3258 on a H97m Pro4, latest Bios 1.9 Running Windows 10 10240. 

What I thought was a Win10 issue turns out to reach all the way to current Win7 users ever since Microsoft released KB3064209 - If you have a G3258 and restart after this installed, you go into a re-start 'death loop' --- that is, until you go in the Bios and select ( 1 ) core ONLY, or shutting down 2nd Core.

This update, the June Intel Microcode Update did something terrible to the G3258, just check the web yourself you will see it.  I do understand this may be a Microsoft thing, but at the same time as I looked at the past bios Update for this AsRock board, most of the past revisions all include something to do with the G3258 particularity, so maybe this IS NOT a MS issue only and my board needs a new Bios to fix whatever the powers that be have decided on whatever necessary update was needed out there to change the CPU codes.  I suspect this update was integrated into all Win10 builds after 10130. which my board ran fine with zero problems (10130) but afterwards, that's when I started having the death loop problem.

Any fix or knowledge would be appreciated.

So you're saying you have win 10 10240 which is the first series RTM TH1. 

This has nothing to do with ASrock, and this falls on Micro. 

If you didn't save the 10130 DL, then you're out of luck and will need to wait till the next TH release to see if it's corrected.  Or you'll need to uninstall the new 10240 and roll back if you can get stable enough on one core.

Only if enough people report this same problem to windows 10 feedback, will they look at it. 

This was a windows 8 update,  they didn't hold off till the first RTM and then inject this code.  This update has nothing to do with why your 10240 is looping.

It is  N O T  solely a Win8 Update - Win7 users with the G3258 are reporting they got this via windows update:

https://www.microsoft.com/en-us/download/details.aspx?id=47661

The Win7 guys was my 1st real clue that this wasn't a problem only to the brand new Win10 -

That being said, can I ask how do you know for sure that it's not integrated into 10240? I  myself, and believe me I've tried, cannot get anyone at MS to tell me this or anything else on this issue!

Again, my questioning any AsRock involvement was due to this:

 http://www.asrock.com/mb/Intel/H97M%20Pro4/?cat=Download&os=BIOS

1.2 directly mentioned the G3258 of all the ga-zillions of CPU's intel makes - - - even 1.9, the latest and the one I am using as I type this, directly states the very same thing the MS update released and altered CPU codes -

Around the same time this update was released, shortly afterwards build 10158,10159,10162,10166 and now 10240 - ANY attempts to update to ANY NEW BUILDS STARTING WITH 10158 started my death loop, while everything ran 100% fine starting with 9987 up to 10130.  Something changed in the builds - and yes, logic says its MS to blame - however, that being said - I get to ask AsRock this question I am asking, especially since THEY mentioned the creepy G3258 specifically. 

Look, i'm simply pointing possible issues based on circumstantial's and that's it.  But if you have proof that's not in the build I would love to see it

You posted your CPU, but not storage. If you don't have  NVME storage,  please  try to flash the 1.50 UEFI,  and if you don't have NVME,  there was no reason to flash the 1.90., and shouldn't have been flashed to it. 

Which versions did you upgrade to and which if any have you cleaned installed ? 

Not to be rude, but asking ASrock a question about a OS that isn't support at this moment isn't something that should be done.  It's for IT people. 

Please hold on for a MOD to see if they can help better with a OS you shouldn't be running.  With the info you posted and the additional ones I asked,  it will give them a better chance to assist you.

Thanks and hope you get this resolved.

Support for the G3258 was added for all ASRock 8 and 9 series chipset boards in 2014, but I don't think that was a microcode update. Since the G3258 is a Haswell processor, it should work with any Haswell compatible board. But there was an issue unique to the G3258 that caused the need for an UEFI/BIOS update.

While the G3258 does not support Turbo, the way Intel processors currently are over clocked is via the core multiplier. That is tied to the Turbo option, even if some board's UEFI/BIOS allow users to "Disable" Turbo but still OC. That is smoke and mirrors, Turbo is Enabled if you can increase the core multipliers.

ASRock added a UEFI/BIOS feature that removed the Turbo option if a CPU did not support Turbo. That did not allow the G3258 to be over clocked. I experienced this myself in a Z87 board. The "Support G3258" UEFI/BIOS update put back the Turbo option, at least for the G3258. Z87 boards even had a Beta BIOS that did that.

Support for the G3258 might have included a microcode update for 8 series chipset boards, but not 9 series chipset boards. ASRock normally states "microcode update" when that is done, but you don't see that in the 1.20 update for your board.

MS doing microcode updates? Scary stuff IMO. Besides Win 10 where the updates are outside of our control, I never let Windows Updates apply automatically.

If your board will POST into the UEFI/BIOS after this MS update, IMO ASRock has done their job fine. If Windows won't boot after an MS update, my finger points at MS.

Thank You parsec, you broke that down so well even I (:P) can understand, and I came in here asking questions will the full understanding that most likely 90% of this was Microsoft's doing  -  in this problem, this ranges from Win7 up to Win10 builds after 10130, and other board manufactures including MSI, Gigabyte, even Asus, with the only thing in common is that update + the G3258 cpu.  It's posted enough everywhere to be found easy for anyone to see.

I have 3 builds withing the last 3 months on AsRock boards, this G3258 is my 'lesser' builds of the three and the only one giving me problems.  The other 2 is a 4790k on a AsRock Z97 Extreme6 and a 4690 on a AsRock Z97Extreme3.  I have another lesser build of a G3250 on a MSI board, and none of these have ANY problems whatsoever with anything.  

Seeing the G3258 specifically mentioned in the Bios updates is what originally led me here. Again (easy odiebuggs easy good lord) I was just data-mining for information that might lead me to a solution and felt it completely ok that I at the least get to ask a question, not blaming.  Thank You again Mr.Parsec :)

I shouldn't post after working long hrs, easy to get annoyed and post wrong things as a retaliation.  

One Microsoft post for that update shows only as win 7, but ignore which OS. 

Microcode is written to the CPU and for safety it's read only so no reverse engineering.  

Usually Intel sends Microcode patch out to be a BIOS update, this time it went to Microsoft and  in win 10 it could be in boot or in the kernel.  

I don't know what you have for a clean install build or if you have one at all, but if you do try the other install if you have one. If you installed in UEFI, try MBR.  If this was all upgrading and you don't have a install, you will have to wait.  EFI boot from BIOS/UEFI might have an effect. 

Have no clue if this would work, because loading could happen and it's boot might not be the cause,  but with windows given the micro, two things can happen, they can ignore it and leave it in, then ASrock might have to find a fix using UEFI from Intel if they can't find work around.

The other is that Windows will get a patch from Intel to patch it or remove it until problems like TSX instruction set can be fixed or the new bugs that it creates.  

The first google hit for windows 10 and this CPU,  death loop is a MSI board,  and we see asus. So it's not only ASrock affected, nor is it one OS, this falls back to Intel and chipset.   

You'll need to wait and see what happens, but contact support directly from the ASrock MOBO website and report it so they know to work on it.

Unless a MOD posts they have reported it.  

Other people could read this and it might help them.

Greetings, This is ASRock Technical Department.

The Microsoft released an update "KB3064209" to update Intel Microcode.
The new microcode will cause the system cannot overclock except Z-series platform.
On your case, if you would like to keep the overclocking function on H97 platform, please use Windows 7 or 8.1 without install the update "KB3064209".
If you would like to use Windows 10, we will build a BIOS that update Microcode for you.

Kindest Regards,
ASRock TSD

This is great news that ASRock is going to look into this, but to reinforce what Londo said in the original post, this is not necessarily an overclocking problem.   I have an identical setup ( G3258 on an ASRock H97M Pro4 ) and experienced identical problems with Windows 10 Insider Preview.   Builds above 10130 incorporated KB3064209 which was touted as an Intel microcode patch for Win 7/8x, and those G3258 users who chose to apply it in Win7/8x immediately experienced problems.
In Win 10 Insider Preview you don't have a choice about KBs that are applied - builds above 10130 automatically include KB3064209 and it is still there in 10240 which as far as we know is RTM.   You will get stuck in a vicious boot loop unless you disable a processor core.    This behavior is not specific to ASRock or the H97 chipset - the common denominator is the processor.
 
I assure you I'm not overclocked - in trying to work through this problem I ultimately had to reset CMOS, so I have the most vanilla machine imaginable at the moment running nothing more than an OS and an anti-virus.   And so it shall stay until someone comes up with a solution to give me back my  other processor core.   But then I have that luxury as this is a new build.   The issue will not be so kind to others.
 
Thanks again for looking into this.   Crossing my fingers for a speedy solution.

The solution was posted above yours,  look above your post,  where ASrock TSD said they will add it to the BOIS and it should fix the problem.  

If you need help finding the one above your post, post back. 

 If you don't want auto update then you turn them off.  Only people who shouldn't be using preview are stuck with ( KB's, ) updates.

WOW, OMG yes yes yes, please please please!! Thank You so much - I don't know what to say, just to hear that someone in the Company cares enough AND honestly acknowledge the issue AND offer a solution, this is a first anywhere I know on this growing issue.  I always liked AsRock Motherboards, me thinks I made a really good choice :) YAY for me!

Thank You 'oldebugs' seriously, all jokes aside you rode this out all the way to the end, and I sense your hyper-persistence in trying to help out might had helped get the much needed attention on this.  I was really about ready to give up. I learned a couple of new things today. Nice...

AsRock TSD - just a quick fyi, my system won't boot with both cores overclocked or not.  Thanks Again!

Dear ASRock TSD,

Can you build new bios for H81M-HDS(v1.00) too? We have many of these motherboard, and the problem as same. 
Thank you!

Let me understand this clearly.

This MS update when applied on the non-Z chipset boards that have a non-Z OC BIOS/UEFI, then cannot boot even if you load the default BIOS/UEFI settings?

Someone could only get their PC to boot if the disabled one of the CPU's cores?

What a nice gift from Intel and MS! Ouch Angry

Seems like a punishment from Intel. Then we need a special BIOS/UEFI update to get the PC to even boot? Shocked Censored

Just spent a few hours wrestling with this. On a fresh install my H97M, G3258 combo was boot looping. At first thought it was drivers I had integrated into the OS ISO then I found this thread. I don't think Windows 10 auto update is a good thing.

ASRock_TSD, can You make BIOS for motherboard H81M? I want install Windows 10, but i dont know if it will work. On Windows 8.1 I dont have problem with OC (even with an installed this update).

I didn't had any problem with the oc and the KB3064209 update on my Windows 8 install, but wanted to install the UEFI 2.10 on my H81m-HDS anyway since I plan to install Win10 soon.

To my surprise the UEFI 2.10 update removed oc options from my oc tab, specifically the option to set the multiplier! So I can't oc my G3258 with UEFI 2.10. After I switched back to 2.00 I could again...

The bios updates that "fix" H and B series motherboards with windows 10 and the G3258 remove Non-Z overclocking. H and B chipsets were never intended to provide overclocking features and it seems intel is trying to push manufacturers to remove these features.

Xaltar, do you have access to these BIOS updates? I personally do not overclock my G3258 with my H97M Pro4, and I would greatly appreciate if you could provide links to the BIOS files linked earlier in this thread which are now down.


Posted By: Xaltar

I am afraid not. The bios updates should be made available on their respective product download pages as and when they are ready to roll out. While I am a moderator I am not in fact an Asrock employee and so am subject to the same conditions as any other forum member. Hopefully these updates will all be put up soon. Its a pretty low blow from MS and Intel, both for the consumer and all the manufacturers that had added overclocking support for the G3258 on budget boards.

Hi, hope I'm not too late to request this, but having the same problem with the H97M-ITX/ac board. Hope that can get a BIOS update as well. Thanks a lot for your quick response on this ASRock.

A couple days?  Would it have killed you to leave the H97M Pro4 bios up for us rather than forcing us to wait in limbo?

Let's not forget that it is Intel and Microsoft with the KB3064209 Windows Update that caused this problem, not ASRock or any other mother board manufacture.

If we asked Microsoft to fix this problem, what do we think (know) their response would be?

Has anyone affected by this tried rolling back this Windows Update? I highly doubt it would remove the problem, but I don't own a mother board that is affected by this Windows Update. I'm simply wondering what happens in that situation.

Blaming mother board manufactures for this problem, or being upset that the fix ASRock has said they will provide for us is not available yet (IF that is true) for a particular mother board, does not make sense at all. ASRock did not create this problem, and is the only one that will fix it for you.

Please have some patience and respect for those that are helping you with a problem they did not create. Handshake

It is just that it has been super frustrating.  And trying to bring this problem to Microsoft's attention has been utterly futile.  Like any other company, the just assume that any problem you have with their product (Windows) is either a fault of your own doing or some device. -_- At least ASrock is doing something! Running in single-core mode for the past month and a half just to get around the problem with Microsoft's unnecessary change/update has been a drag.

There is no oc options in the bios why is this happening?

Just information
I guess all of the mb bioses already updated with new bios but
It disables non-z oc so for you who uses h and b series mb
Can't oc anymore. Correct me if i'm wrong
It's really disappointing i have to buy a new motherboard to oc this
I guess rather than buying a new mobo i will upgrade this processor
To i3 soon
It's really disappointing intel did this on purpose.

I have another issue with OS 8.1 in 2 identical G3258 PCs. 
G3258
Asrock H97M -ITX/ac
G Skill 8GB
1000GB WD

There is a problem in my Device Manager...
When I updated W8 (Pro) to W8.1 (Pro), I got in both G3258 Pc , a problem with Device Manager: "Other Devices: SM Bus Controller (problem)"... and I could not find a Driver update to solve it! ... That problem was not present in either PC before I updated to 8.1 ; and I have no idea what device that is!    
... and of course they both failed to upgrade to WIN10...

Does #8 come after you rename the file "mcupdate_GenuineIntel.dll" and not before? :

"8.- Boot from windows installation media and install normally":


Shouldn't be like this?:

1.- Enter bios
2.- Go to "Advance" option
3.- Click on "CPU Configuration"
4.- Click on "Active Processor Cores
5.- Choose "1"
6.- Go to "Exit"
7.- Select "Save and exit"

Rename File in Sys32 "mcupdate_GenuineIntel.dll"... then Install Win10? 

 or you Install Win 10 first and  then Rename file?... I am confused here.

8.- Boot from windows installation media and install normally

Thanks... but it really doesn't matter if the file is renamed before like I did... Win 10 installed but there were aftermath problems -  and the same original file was reinstalled by W10 ... so I will have to rename it, and see if the PC/Win 10 will be functional after resetting Bios:
So far with 1 Core, the System is crippled and many functions are absent; like the Start Menu/  desk set ups etc...

PS - On the third boot it stopped and got a blank screen before I could rename the file and resetting bios... so it looks like I have to reinstall an image of W 8.1... and wait for a real fix.

I found leaving both cores on but just turning off overclocking worked. It's (I think) easier to implement in your BIOS (or mine anyway- ASUS) and then switch back to overclock later- just set your multipliers to 32 or AUTO (i.e. stock speed, no overclock). Then change multipliers back after rebooting after the file rename in your BIOS.

Hello,

it looks like I have a simillar problem: Since 3 days, I'm triying to install W10 on my Asrock H81M-ITX/WIFI and it fails.

So I got back to Win 7 and everytime I install the KB3064209 the system is unable to boot.

I think I have the last Bios too.

AVQPP's solution worked for me! I kept running into that 409 update basically wrecking my Win 7 installation, took me three clean installs last month to isolate which update was doing it. 

Then I found it online and was just like "ahhh.. well then." I wasn't even overclocking my G3258, I just leave it stock. But now I'm curious, with AVQPP's workaround, is it possible to safely overclock after installing Win 10, renaming the file, and resetting the cores to both?

There weren't any update when I checked late last night.

I installed the new 2.50 firmware for my H87 Performance and can confirm that my G3258 is working with 2 cores in Windows 10.

However, even the slightest overclocking now crashes Windows (had stable 4.5Ghz before).

@AsRock
Are you guys ever planning on enabling overclocking again in a new bios? I had super stable OC before and it's a pain to go back to stock speeds.

Win 10 has more bugs than any other version I used before... there are too many breaches to all browsers  even  Ms Edge (popups/malware...  )... 
Unstable: the latest one:  "Kernel_Security_Check_Failure" which made my system un-bootable and the so-called Repair failed to restore/repair anything.
So far W10 is a looser in by books: I wonder how much money ( all those who are all praise)  got from MS...
I may try it again in 10-11 months , maybe... W7 and W8 look great compared to this dud...

I am sorry to have to say this but there will not be a BIOS update to allow for OCing on non-Z platforms under windows 10. This restriction comes down from intel and is not the fault of ASRock or any other manufacturer. Intel is within its rights to set parameters for how it's products are implemented.

The G3258 is a great little CPU, I am using one as I type this overclocked to 4.6ghz on my ASRock Z97 Extreme 3. The problem is that despite its phenomenal overclocking and single core performance, often matching or bettering an i7 4790k in this regard, it still only a dual core CPU with no hyper threading. While this is more than enough for most applications it has become a problem with new AAA titles that require more than 2 threads. An AMD Athlon 860k and a decent FM2+ board will perform better in a gaming scenario when paired with a decent GPU. I would recommend the http://www.asrock.com/mb/AMD/Fatal1ty%20FM2A88X+%20Killer/" rel="nofollow - ASRock Fatal1ty FM2A88X+ Killer  or if you are on a tighter budget the http://asrock.com/mb/AMD/FM2A88X%20Extreme4+/index.us.asp" rel="nofollow - ASRock FM2A88X Extreme 4+ . Both of these offer great features, superior power design than cheaper options and likely better overclocking capabilities than you would find in the budget segment. I recommend the Athlon over the APUs on the FM2+ platform only because they are cheaper than an A10 XXXX and lack only an iGPU which you will not need with a discrete GPU installed anyway.

Two thumbs up and my vote for the ASRock FM2A88X Extreme6+

Other than the sometimes buggy Atheros Killer nic and one more(7vs8) sata ports on the "Killer' board, with the Extreme6+ your getting 8+2 VRM, 2 PCIe 3.0 x16 slots(one @ x16 or two @ x8), and Dual BIOS chips.

If you want to use Windows 10 on a H81 board  ( with overclock on g3258 ) you can do the following.

1. UPGRADE to windows 10 from windows7/windows8. For some reasons, upgrading, even if you check the "keep nothing" option, will not disable to overclock, will not cause black screens or any other errors.

2. Disable the overclock or disable 1 core or both of them. Install Windows 10. Search for "mcupdate_GenuineIntel.dll" in system 32 and rename it in "mcupdate_GenuineIntel.dll.old". To rename it, you need to change properties, go to security>advanced and there you will need to change the Owner. Click "Change", go to advanced, go to "Find Now" and double click on "Users" from the drop down table ( it should be before the last ). Now go back to Security and in the "Group or user names" tab click "Edit" on any of the listed groups/users. Check "All"  for administrator and users in the new tab that you are prompted. Reboot. Enable both cores and you can overclock now.

Don't use the latest BIOS, because the microcode disables the overclock option in the BIOS.

Bit of thread necromancy, but for people who might be putting together a real cheap W10 build...

1) Update the board to latest bios & restore default settings.
2) Install windows 10 - let it update.
3) http://www.asrock.com/mb/Intel/H81M-HDS/?cat=Download&os=BIOS" rel="nofollow - Download BIOS v1.91 Use the instaflash version, and put it on a fat32 usb stick.
4) Boot into uefi and flash v1.91.
5) Reboot and OC away

 - note - under Win10 you can only OC via efi, not from within windows. I had to lower the OC by approx. .25 GHz to keep windows 10 happy compared to win 7. But, other than that, all is well...
