Socket 478 Motherboards with PCI-E Slots

Postby Carlos S. M. » 2016-10-30 @ 01:57

Well. I started a thread about a kinda odd type of motherboards, Socket 478 motherboards with PCI-E slots which are not really common compared to their AGP counterparts, but still useful for some thing and maybe make fun with them, especially when testing and comparing.

Here a list of motherboards i could find arranged by chipset, it might be incomplete

It seems like I might have one at work in a decommissioned system. I'll have a look. Thanks for compiling this list, Carlos!

Nice list!!

Now that I check, the full name of the "MARSHAL G31(?)" on your list is MARSHAL MAMR-G31-478.

I have a Biostar P4M900-M4 - it works surprisingly well with win98. Oh it also uses DDR2.

Some boards to maybe add: Colorful C.915P-478, PC Partner 915PMS4-A48P (both Intel 915P); Asus P4RD1-MX (Radeon Xpress 200).

I used P4GPL-X for years with Asus CT-479 adapter and Pentium M 750 @ 2.6 GHz. PCI'E slot was filled with 7950GT at first, then 8800GT later. That system rocked! Still have CT-479 and Pentium M 750 working in P4P800-SE system, sold the P4GPL-X with regular 478 CPU back in 2009.

AMD chipset on a 478 motherboard? That's pretty cool :)

It was an ATI Chipset and this one was made before AMD bought ATI, ATI started making chipsets since 2002

I once had an opportunity to acquire a DDR2 PCI-E s478 board and regretfully I didn't take it :(
Carlos S. M. wrote:Adding them to the list

Mind if I create a list on Vogonswiki based on your list here, Carlos?
It would fit nicely with the s370/Tualatin/C3/ISA list me and another Vogoner made a while ago :).

Yes. No problem

We can still use this thread for some info and reporting some motherboards

Cheers :). I've added this page to the list of interesting Vogons threads, I'll add this list on its own page once I can take my time to do it.

By all means continue, my list is to add, not to replace :P.

The Asus CT-479 were really nice. Had a couple of them and used them with a Pentium M 730 and Celeron M 350 on a P4GD1 and P4C800-E Deluxe. The CT-479 also ran in a couple of unsupported boards too: http://www.xtremesystems.org/forums/sho ... therboards

Unfortunately none of the CT-479's survived my abuse. :depressed:

Got the MSI 945GCM478 yesterday. One cap popped after turning it on, so I replaced all the VRM incoming caps with some lovely Panasonic :)

I'm benching this board at the moment, so any questions please let me know ASAP as I will pack it away soon enough.

I've finished benchmarking Northwood 3.4 and now Gallatin 3.4. Both CPUs got detected without any issues, no warnings about power draw, but at least the EE 3.4 is not on the supported list.

BIOS is fairly minimalistic. It uses DDR2 memory, so it's running at 333 MHz, that's the highest memory divider available. Flashed the latest 1.2 BIOS from a boot floppy, no issues and no complaints so far.

I guess 333 is the base memory clock, so the RAM is running at DDR2 667 speeds

with FSB 800, all the standard possible RAM speeds are:
DDR 320 (200/1.25, FSB800 doesn't support DDR 333)
DDR/DDR2 400 (200/1)
DDR2 533 (200/0.75)
DDR2 667 (200/0.6)
DDR2/DDR3 800 (200/0.5)

DDR2/DDR3 800 (200/0.5)


That sounds right. I can take some BIOS screen-shots. The divider can be set manually, but 200:333 is the highest available.

Actually, I should start doing some motherboard review videos. Not so much about the performance, but about features, BIOS options, that sort of stuff.

Fair, also is worth mentioning the Intel 945GC only supports DDR2 400/533/667, so 200:333 is the fastet possible. Many LGA 775 945GC mobos supported FSB 1066 and 4 GB RAM (shrunk to 3.25 GB though) unofficially, idk about these uncommon Socket 478 with modern chipsets, like this MSI mobo and the AsRock P4i945GC cappable of running FSB 1066 or more than 2 GB RAM, the G31 mobo should do FSB 1066 and 1333 fine, plus DDR2 800 support. Anyways good luck with that mobo.

Because... why not ?

And yes that is bootable as well.

When VRAM is more important than RAM :)
Fire Strike 5k.png
Valid : https://www.3dmark.com/fs/15471792
Pretty good for 15 year old CPU (first HT enabled model of Pentium 4).
Usable RAM for Windows 7 32-bit on this platform = ~3,12GB (3200MB).

Board sadly doesn't support Pentium 4 Extreme Edition 3,2GHz (Gallatin).
I confirmed it (not sure if ucodes are the issue, because CPU cooler was cold even after few minutes)

PS.
Going over 4096MB VRAM usage = instant crash/error (because virtual memory in 32-bit Windows is limited that way :D).

quite interesting, so in theory you could pair a celeron 1.5 (slowerst cpu with PCIe access I'd imagine) with say a GTX 1080 Ti
Ryzen 5 1600 - Gigabyte B350 Gaming - 16gb DDR4 3200 - 240GB M.2 - Windows 10 Pro
Core i3 3470 - Dell B75 Mobo - 4gb DDR3 1333 - 500gb HDD - Windows XP
Opteron 180 - Epox EP-9NPA+SL - 2gb DDR500 - 320GB HDD - Windows XP
