[Solved] Need help updating microcode to support a new cpu

post #1 of 23
Thread Starter 
I just did the mod that lets you install an LGA 771 Xeon cpu in an LGA 775 motherboard, and the mod worked, and I can boot into windows, but some functionality like speedstep and SSE 4.1 is missing when I look at the output on cpuz. I think it's because the microcode isn't present for the Xeon cpu, and it's using some kind of generic settings.

Does anyone know of a way to mod the bios on my system to properly support this cpu?

Here are the system specs:
Motherboard: Gigabyte p35-ds3l version 1 (uses an Award bios)
Processor: Xeon E5440 (SLBBJ revision E0)

Any help would be great.

Edit: We figured out how to do this.

There are now guides on updating the microcode for Award, AMI, and Phoenix BIOSes:

ThrottleStop might be able to help you if your CPU is supported. Post a screen shot of CPU-Z so I can have a look.

Yeah, it looks like ThrottleStop may be able to help with enabling speedstep, so thanks for the suggestion. I'd also like to be able to enable SSE4.1 and the other functionality if possible.

I can't take a screenshot of cpuz because the computer's at my parent's house, but here's someone else's screenshot:

The main difference is that my cpuz screenshot is missing SSE4.1 and VT-X. And as I mentioned above, speedstep was also not working.

I've heard of other people adding cpu support to their BIOS, and this guy has a good explanation here (for AMI bioses): http://www.overclock.net/t/742636/how-to-view-a-bios-before-flashing-and-add-cpu-support, but I haven't been able to find any programs or instructions that work for an Award bios.

Thanks, Lixtra +rep. I'll try it soon and let you know.

Can you please tell me exactly what you did and how confident you are that it should work? I'm only asking because I don't want to brick the motherboard.

I'd like to learn how to do this myself. Did you insert the E5440 microcode from another bios? What program or method did you use to modify the bios? Are there any tutorials or guides around?

Lots of people are having this problem with the lga 771 to 775 mod, so a detailed thread explaining how to do this would probably help a lot of people.

Thanks

There are many tutorials around the web, this one for example.

Ok.. thanks for the link. I think that I pretty much figured out how to update the microcode from that.

The only thing I'm unsure of is which donor bios to extract the e5440 microcode from. Can you just extract it from any Award bios that supports the e5440, or does it have to be from a motherboard that's similar to mine?

Can you please tell me what bios you extracted the e5440 microcode from?

Thanks

Find out the LGA 771 motherboard that natively support E5440 & go download the BIOS file for that motherboard. Then extract microcode from the downloaded BIOS file. The CPUID for E5440 SLBBJ is 1067A (in hex: 7A 06 01 00).

Alternative, you can just download the microcode file from Intel website but then you need to find the extract tool to extract microcodes from the file.

Thanks, kizwan +rep. I decided to just download the microcode from Intel.

For anyone else that's interested, you can download the microcodes directly from intel by going to: https://downloadcenter.intel.com and searching for your processor. A tool to extract the microcodes is called microdecode.exe, and you can find it here. If you're unsure how to download the file at that page, just goto File -> Download.

That file also includes full instructions (in the 41MTS2P3_SLIC.txt file) for adding new cpu microcode to an Award bios from someone that recently did this.

Has anyone ventured into the Lxxxx series xeons, they are also socket 771 processors. I've found a great deal on ebay and was wondering if my Evga 780i SLI would support it. I hear the X54xx would run on my board so I assume that the Lxxxx should also work.
