Updating bios for gigabyte p31

The older non-E0 stepping processors often don't need a microcode update to enable these features, so if you do try it, buy one of those.The reason this may not be possible is because Intel has their own proprietary BIOS that nobody currently knows how to MOD (even by manually hex editing the BIOS).Some chipsets may be checking for this and may be blocking the system from booting.Make sure you only buy Xeon processors with a FSB and TDP supported by your motherboard.We'll explain how to verify these things in the sections below.And later in this guide, there's also a list of motherboards that have been tested with this MOD.However, if your system only supports the 95W Q6600 with a G0 stepping (and not the 105W B3 stepping), your system may only support 95W and lower processors.If you aren't sure what TDP your motherboard supports, I'd recommend going with the 95W and lower Xeons only.

Each row shows an LGA 775 processor in the 1st column.

If you don't need more details about the topics shown above, you can skip ahead to the next section: Next, make sure your BIOS supports a similar LGA 775 CPU.

By 5xxx series we mean any Xeon whose model number ends in 5xxx (this includes all the E5xxx, X5xxx, and L5xxx processors).

If your motherboard and BIOS support that processor, you can run the LGA 771 Xeons shown in the second column (if your chipset supports it).

You should only buy Xeons with a FSB and TDP less than or equal to the values shown (unless your motherboard supports higher).
