I thought LGA 775 boards used DDR2 and PCI-Express.

FFXIhealer: LGA775 was platform with huge spread of used slots and connectors. Depends on release date, LGA775 boards can be equipped with DDR1, DDR2 or DDR3 RAM, and AGP or PCI-e connector for GPU.

WallpaperDesigner: I would say, that ASRock ConRoe865PE is best motherboard with DDR1 and AGP connector, but be prepared for higher prices (and I mean it, I wanted to bought that board too, but was beaten by some crazy guy, who pay 121€ for it in bidding war with me).

It looks like 775, AGP and DDR1 is an unusual combination. Perhaps a 478 board and another processor would be a better option (seeing as P4s are very cheap compared to the boards).

If they are too expensive, maybe share what you want to do with it ?
As you said, DDR1 and AGP are unusual (to say the least) for LGA 775.
That's why I think, there isn't a "best" moitherboard - but few MBs with pluses and cons.
Another option is ARock 775Dual series or 4CoreDual series.

Here's a thread where you can check LGA 775 with AGP : LINK

The early LGA 775 board used DDR1 and AGP.

It is just that they moved to PCI-E and DDR2 fairly quickly.

I'm fairly certain that that is incorrect. The LGA775 platform was introduced alomg with the the intel 915/925 Chipsets. These brought support for PCI-Express and DDR2. The Intel 865 and 875 chipsets are very different. DDR, AGP, and in the case of the 875, a special link to allow for gigabit Ethernet outside of the PCI bus limitations.

There exists both 775/865, 775/875, and 478/915, 478/945 boards. The purpose of these was to enable cheaper upgrade paths, but they were not mainstream solutions.

Nevertheless, some Prescott cores were made in 478, and unless you have a specific need for 775 with AGP and DDR, it will be far less expensive to purchase a 478 processor with an 865/875 board.

My aim is to replace the existing motherboard in an early-2000s gaming PC.

I currently have an ECS board with LGA 775, AGP and DDR400 but it's horrible (no fan control or adjustable vcore). An additional goal is to overclock a P4 to at least 4 GHz.

Is there a noticeable performance difference between the 865 and 875 chipsets?

Yeah, it looks like my thoughts on that were wrong.

Looks like PCI-E boards came out in 2004 and AGP boards came out in 2005 according to what I could find with BIOS dates on Gigabyte's site. Maybe different for other mfgs, but Gigabyte was what is coming up first when I search.

This is one reason to hoard up when things are cheap and enjoy later, 775 and agp is slowly getting to be kinda expensive depending on what the community is doing but there are usually dips when interest is low so you should still have a couple of opportunities before it gets out of hand.

LGA 775 NetBurst only AGP boards are still very common and cost next to nothing. Core2 compatible are harder to find, but not very rare either.

at least 775 AGP isn't as badly priced as AM2/AGP, good luck pairing Phenom with AGP

Well, how can be, when you can still buy NEW board from ASRock with AGP probably in your local shop for few dolars (775i65g r3.0)?

ASUS P5P900-VM
Socket LGA 775( Intel® 65nm Pentium D/Pentium 4/Celeron CPU) ✓
AGP(8X) ✓
Dual Channel DDR400 ✓
Windows 98 drivers, Windows 2000 Drivers, Windows XP Drivers ✓
It also has SATA.

I have one running a Prescott 3.0 P4 with a Radeon 9600 Pro and 2x256 DDR400 RAM with Windows 98 installed, and i should say the performance is awesome, stability is awesome, however i had problems with the SB Live! DOS support not working.
But in general it is a pretty good motherboard, and i don't think that it is rare at all(at least where i live)

LGA 775 Motherboards with AGP Slots

If you aren't concerned about using later Core 2 Duo cores, it actually can be inexpensive. The link above has a fairly comprehensive list of motherboards and their capabilities.

Thanks for the information guys.

AM2NF3-VSTA is also an option if you can find one, its for AM2 but supports up to Phenom II X4 970 which is faster than any Core2 Quad, its more comparable to an i5 750

IF someone could find one with 45nm Core2 support -- now THAT would be rare.

Well, that's mine ASRock 4CoreDual-SATA2, with unofficial BIOS. I'm currently running it with Pentium E6500K, which is "Wolfdale-3M" (45 nm) CPU.

I have used the Asrock 775i65G. I had the 2.03 revision and 45nm CPUs worked on it with the newest BIOS. There is also a 3.0. I found the best way to go was to get a Wolfdale CPU with 800 MT/s FSB because the 865G has some annoying issues with 1066. I had the 3 GHz Pentium E5700 on it. It was a good board. I used it to experiment with combining massive CPU power with old 3D cards.
