Hi there,

Just flashed an OptiPlex 360 with the bios provided here, upgraded it from Pentium E5200 to modded Xeon E5450 and it runs like a charm.

1000 thanks!

Cheers

Just replaced the Core2 Duo E7500 with a Xeon X5460 on my Optiplex 380 and it worked without needing any BIOS modifications 
1. The PC is an Optiplex 380 (the 'desktop' (DT) size case). Motherboard code is 0HN7XN
2. The CPU is a Xeon X5460, SLANP version (C0 stepping)
Apart from putting the LGA771/775 adapter sticker on the CPU and cutting the lugs off the CPU socket, I didn't have to do any BIOS mods. Windows 10 and Linux Mint 21.1 both work fine. The Dell BIOS is A07, and the BIOS screen shows the new CPU details.
Performance using Geekbench5 running on Linux has gone from 446 (single core) and 787 (multi-core) before, to 502 and 1457 respectively.

I bought mine from China - x5472 and it seems to not boot, it had a custom solder job on the cpu so I assume thats why. Where can I get a Xeon (trying to make this into a plex server for my gf stepdad)

Hello, I'm new to this thread and I came across it while trying to get my Xeon x5460 to work on an Optiplex 360. I have tried running the exe in the appropriate file for the bios mod found in the first post of this thread, however it gives me an error: "invalid command line - please verify the program was executed correctly". I don't understand why this is happening... am I doing somethig wrong? maybe someone has a clue? 
Unfortunately many links around the web are broken, so i can't get my hands on another possibly working file... The Optiplex 360 is currently running an e8500, 2*2GB of ram, win10, and I've tried flashing the mod while on A05 as well as A07 original bios, no luck either way. sSpec of the x5460 is SLBBA.
Hopefully there are still people interested in this project that can help me out.

Thanks! I had to go through a pretty painful DCCU installation because of Windows’ stubbornness… but after updating, the x5460 works just fine. I should have used Linux from the beginning ;P
