+1 to PcBytes - it's also worth pointing out that LGA 775 does not mean universal Pentium 4-Core2 Quad support. There are chipsets that only support Netburst, chipsets that only support Core, and a few that can support at least a smattering of both.

Don't bother with supper crappy 775 boards as they are often as bad as oem boards (gag a maggot bad). If you are lucky to find a mid range or better 775 board you can pretty much use almost any 775 cpu but overclocking them to the moon and back is another story. Well through a Lot of trouble modding my xfx 780i when I had it so I could both overclock and under volt a Q8200 to 3.2ghz but using only 1.16v or very close to that after vdrop 😮

If you want a a crazy fast and rock solid 775 rig find a good DDR3 board like a late model x48, p45, or a 790i but they are expensive and getting rare.

+1 on X48. Mine is still running strong after 6 years. Have an X38 that's older than that and still going strong too. 😁

That said, neither lists Netburst chips as compatible or supported - I don't have such a chip to try and challenge Intel's specifications (nor do I really care - I wouldn't "waste" an X38/48 on a P4; they're really designed with Core 2 in mind), but that's what their manuals/documentation shows. 😊

I guess I'm pretty lucky for getting an MSI P45D3 Platinum for just 10 euros. 🤣

Ya I do not run into much lga775, mostly 478 systems. The final straw for me with this board is finding out that it does not support SLI, even with x16 slots. Nope, good bye HP garbage it is time to hunt for a good SLI 775 board that supports the p4! haha 😀 currently bidding on a Asus 750i chipset board with official p4 support and SLI. 10 hours left on the clock! Got an ASUS P5N-D for $16

My in-progress Prescott system tells me to contact HP to update the cpu microcode when it starts up and that the cpu is unknown. Yet the bios detects it as a Intel Pentium 4 670, which it is. Seems to work good so far, if it runs stable and does not give you any problems who cares right?

At least it lets it run. Some boards are complete bungholes about this.
I investigated the voltage regulator on an IBM 440BX board, this was one of their fancy "Intellistation" workstations that people paid a ton of money for when new. The kind of thing you'd think would get good long term support.
I found that the VRM was Coppermine compatible. Great, so I plugged in a basic 600E Coppermine CPU. It would boot, but then the BIOS would pop up a message saying the current CPU is "unsupported", and after acknowledging the message it would forcibly shut off. "Yeah this CPU works, but we don't want you to use it so I'm turning off now. Bye." No BIOS update available to fix it, it arbitrarily refused to go beyond Katmai.
Had an equally frustrating problem with an HP of the period, but that involved it refusing to recognize memory that was compatible with the chipset, but didn't exist in the marketplace when the computer was new. Again, that was a formerly high end expensive workstation, where you'd expect more support than they gave.

Hacking the BIOS on machines like this would be an interesting thing to try, but what kills me about these IBM/HP/Intel/Dell etc boards is that they always have soldered flash chips. Why do cheap consumer boards have sockets, but almost every expensive workstation/server board I've seen has the chip permanently soldered? I don't get that, at all. You'd think the more expensive the board, the more serviceable they'd want it to be. If not for this, I could get adventuresome with a flash programmer.

Anybody have any experience with the Nvidia 750i chipset? From what I read on Tom's it is a souped up 650i chip basically. Anyways, replacing the the HP board with a $16 P5N-D Asus board. Oh, and sorry for derailing PCByte's thread! How is your 478 system going?

Fine. Just need to install Windows 7 now.

In the meanwhile I found some weird Socket 478 BIOSes from Japan/China like "ASG","Soking",an unknown one,and the rest I've found are just Lanparty 865PE BIOSes (which is false,since they have VGA files integrated. Heck,even the BIOS strings say Springdale-G! 🤣 )which sadly won't work due to the VT6306 chip that Lanparty 865PE (DFI) has,and there's no way to remove it.

Should make a fairly competent 7 system, hope you find a good Bios for it! Being a noob at bios modifications myself, your adventures in bios swapping and hacking are really interesting to read.
