Hello everyone, I need some IT guys help with problem i faced recently.
Then trying to upgrade from win 8 x64 to 8.1 x64, it says that my cpu does not meet minimum requirement, or says that it does not support compareexchange128.
My CPU is Intel quad core q9400. MB intel dp35dp.
The most funny part is that my cpu supports [FONT=WOL_Reg] PAE, NX, SSE2, [/FONT][FONT=WOL_Reg]CMPXCHG16b, PrefetchW, and LAHF/SAHF.
I really don`t know what to do, or where the problem roots are... :([/FONT]

I've not heard of this happening before so an absolute stab in the dark - have you tried resetting to defaults or updating your bios?

I have tried resetting bios settings to default, but it hasn`t helped.
Because of the Intel, i can`t update my bios, last update they published was in ~2009.
This is ridiculous that microsoft programmers failed so hard...

You may have this solved already, but if not, I have the same problem; "does not support compareexchange128".

My system is dual boot, so I had to jump through a couple of hoops, but if yours isn't, maybe it'll be easier for you.

I formatted the hard drive, reinstalled Windows 8 32 bit, went to Windows Update and searched for updates and installed, then searched again . . . until no more updates were available. I then went to the store and Windows 8.1 32 bit was offered. Nine hours later, I was updated.

I don't know what compareexchange128 is, but whatever it is, Microsoft blew it! The specs should not have been changed when updating. I can imagine that a whole lot of folks had the same problem we have/had or similar.

Hi, I had Windows 8.1 on my system DP35DP + E6750 , after changing CPU to E8400, system refused to boot.
Reason - CPU does not support Non-execute memory proterction, does not support Virtualization, etc.

After many hours of investigation, i finally tried to re-flash latest version of BIOS ( which already was installed ) - and after re-flashing system correctly recognized all available features of new CPU - and Windows 8.1 x64 boots ok now. So may be all that you need is to re-flash BIOS with new CPU installed.

Welcome to Windows EightForums, dshvedchenko.

Thanks for posting your fix. :thumb:

Wonder why that would work, though, since it’s the same BIOS version. :think:

1. I tried clear CMOS
2. I tried enter maintenace mode

Every time I put old CPU it was ok to boot Windows 8.1 x64.
But latest BIOS is 1 year later after E8400 was issued, so it shoudl support it.
I think this is kind of bug in BIOS that it writes something CPU depended during flash.
reflash with E6750 ,didn't help. Only re-flash with E8400 inserted helped to resolve my issue.

Before re-flash BIOS does not see Intel Virtualization option with E8400 inserted - after re-flash it shows it.

Um, nobody has talked about this since 2014? Here I am trying to decide what OS to upgrade to on my XP machine and I'm really wondering. I want to go to 8.1 since 8 will not be supported (WTF is That all about MS?!). I see 7 is still supported except for free online or phone support. I want 64 bit so I won't do 8.1 X86, my software needs 64 it.
The machine in question is not terribly old, has a Core 2 Duo in it, lots of ram etc. But I know that it's often the MB that is the culprit. Is there a way to tell if my MB will do it? As usual, MS is about as much help as . . . well, none. I've kept running XP on that machine for a specific reason which has now gone away, so it's upgrade time. I understand 10 has the same issue.
So, how soon will they stop supporting 8? Will it get the same support 7 is getting - updates etc for 5 years? I do want 8 but if I must then 7 it will be.
I just checked and the MB is an Asrock P43TWINS1600.

Actually, I went to the Asrock sight to check it out. For my MB they have driver updates for everything up to Win 7. So I concluded that 8.1 would not work and ordered 7 pro. Hope I haven't screwed up, but I used 7 for a long time on my old laptop before it died and liked it pretty much, so . . .

Thank you for the reply. It would be cool to be able to use 8.1 or 10 but having just spent $50 I think it will be awhile before I do. As long as MS supports 7 I guess it'll be okay. (they say until 2020)
