New system BIOS update

[marijn720]

Hi there!

I just put together my kind of scrapyard-budget build pc. It has a old xeon x5470 cpu which I modded to LGA771 so it could run in my Asus P5Q Deluxe motherboard. 
Now, whenever I turn on my PC, it says that I need to "Update my bios to unleash the full power of the CPU". My software side of PC building is not my strongest point, so I was hoping that you could maybe help me out with this. 
What new BIOS should I install, and what would be the best way to do so?

Thanks!

Never touch a eunning system, expecially if it wants to install a bios version which doesn't support your CPU.

Why should I not touch a running system? Also, it didn't say what BIOS to install. It just said to update. How do I know if my CPU is not supported?

If your computer boots and runs, your CPU is supported. Updating the BIOS is a huge risk to take, especially on older motherboards that don't have a dual-BIOS system.

The P5Q Deluxe does have a dual-BIOS system if I recall correctly, is my PC not bottlenecked by this ancient BIOS that I'm running right now? (I have no idea how this stuff works)

You're right, it does have a dual BIOS. However, since this board doesn't actually support Xeons, updating to a newer BIOS may render your system unusable (you never know, when using modded socket CPUs), and it can be a real pain to restore the working BIOS (who knows if it works, too). I wouldn't update it.

I understand, thank you. What about the bottleneck though?

If you did the 771 to 775 mod, it's likely that you had to use a modified BIOS that supports your 771 CPU, if you update your BIOS, the working one is going to be erased.

That would mean I got extremely lucky. I bought the board online from a guy who didn't know anything about it, I put in my CPU and it just... worked.

I will not push this luck any further then. Thank you!
