BIOS update. Too old CPU microcodes.

[TIsae]

I bought a new CPU for my Intel DG41TY and installed it. It works, yet there is a couple pf problems. The first is that a couple of insructions don't work. SSE4.1 and Intel VT-x and it cant restart. For restart I must shut down PC first and then turn it on again. Many people are had the same problem, they just modded their BIOS updating the microcodes section. I can't do it because of security against uncertified BIOS files.

P.S. I have the latest BIOS for my m/b, it is TYG4110H.86A.0045.2010.0706.1910 dating 07/06/2010, Yet the microcodes there are from 2008.

Hello Shnab,

Thank you for joining the Intel communities.

Could you please provide us with your processor model?

It is Xeon E5440. People with C0 have no problems with it, but I got the last stepping SLBBJ E0. So a couple instructions don't work, and PC can't reboot.

Here is 2 reports from CPU-Z and AIDA64.

I have checked compatibility with this processor and the motherboard but unfortunately it is not compatible with this motherboard, you can see the processors compatible with your Intel® Desktop Board DG41TY at the following link:

I'm sorry, I know that you will need to use this processor with this motherboard but if it is not on that list any problem or error can be expected.

Best regards,

Ivan

With what you can help is to tell me how to flash my bios with modded .bio file. Or tell me how to change microcode without erasing certificate.

By the way. My CPU have the same CPUID as the supported xeon x3360. It needs the same microcode. Yet bios wasn't updated in years, and Intel just won't let us do it. That means my next m/b won't be Intel for sure, probably CPU too.

You can update the BIOS; you download the latest BIOS version at the following link:

https://downloadcenter.intel.com/product/37164/Intel-Desktop-Board-DG41TY https://downloadcenter.intel.com/product/37164/Intel-Desktop-Board-DG41TY

If you have an old BIOS version I recommend updating at least three or four BIOS version before updating to the latest.

You can check the BIOS update instructions here:

Best regards,

You are kidding aren't you? I have the latest BIOS. They haven't updated it since 2010. There arent microcodes for x3360 E0, which would suit mine cpu just fine.

I'm sorry sir, I see that you have the latest BIOS but please bear in mind that this processor is not compatible with your motherboard as you can see on the link I posted above.

My cpu have the same id as x3360. Which IS supported by my m/b. BUT last bios donesn't have the microcode for x3360 of E0 stepping. The microcode for x3360 and E5440 is the same, totally. They have the same cpuid 0001067A.

The fact that the base CPUID value is the same doesn't matter; the E0 stepping will have different microcode than the C0 stepping (it has different silicon). The BIOS does not have support for this stepping, plain and simple. The board is well past its end-of-life date (it's almost 7 years old) and out of interactive support; support for newer processors will not be forthcoming. The BIO file is secured and cannot be updated external to Intel (and, I am sure, Intel will not compromise on this under any circumstances). Note too that Intel has exited the motherboard business; you won't be purchasing any subsequent desktop board products from them anyway.

Already ordered programmer. It seems the only way to change microcode.

[n_scott_pearson]

You can certainly try. It's a costly experiment, however...
