I might have seen one recently on eBay this past week but it was not standard atx 😢

i know of one: freeway 6400GXR

freeway is a japanese brand, and this board appears to be actually made by a-trend.
but well, they are really rare to find or i would have got one for myself, so better take it easy.

The popular ones are Intel's SBT2 and C440GX+, but both have 24-pin power connector's which probably could work with a standard ATX PSU, but at least the SBT2 requires an odd panel to startup: http://www.os2museum.com/wp/this-is-how-to-feed-it/ .

Thanks, I will add it to my shortlist of motherboards to look for.

I have a Supermicro board, I think its a SUPER S2DG2 as I remember it supporting double PSUs.

The Supermicro board should work even when using only a single normal ATX PSU but I do not think it oficially supports CPUs faster than 700 MHz and I cant check if the 900MHz CPUs run anyhow as I do not own any.

To sum it up, I do not think this is the motherboard you are seeking.

That's the problem. Most of these motherboards support Xeons up to 550 MHz. Some list 700 MHz as supported, I have yet to see one with official 900 MHz support. Some support the 133 MHz Xeons up to 1 GHz, but say nothing about the 900 MHz one. It's mostly trial and error when it comes to the 900 MHz one. It also doesn't help that mine are the QAKES engineering samples, though they were pulled from a 8-way Compaq server, so there must have been time when they were working.

IMHO 99% of boards that support 700mhz xeons will do 900's. It's just like when they list the 1.2 Tualatin and not the 1.4. The problem with ES chips is the unlocked multi. So you need a board that allows you to select the multi in bios or via jumpers.

As I just bought two 900 MHz 2MB chips I searched the net to see if I could find any information telling if they would work with my Supermicro S2DG2 or not, I found this.

Someone used this board in combination with the 900 MHz 2MB chips back then. You can set multipliers with jumpers on the S2DG2 so there is a good chance even the unlocked ES chips could work. Multipliers are only listed for 3x to 7.5x but there are 4 jumpers so even if the CPU starts with double 2x multipliers as Slot1 (usually all on and all off) the manual multiplier settings could still top out at 9x. I think unlocked Coppermine Slot-1/FCPGA CPUs normally top out at 8x using manul multipliers with some duplicated but it would be strange if an unlocked CPU with 9x multiplier did that.

Other nice things with the Supermicro S2DGx series is that it supports 112 MHz FSB and has AGP. I will report if I get my board running with the 900 MHz CPUs but I think the Supermicro boards might be what you are looking for.

Found this topic, I am Raceboy in Thinkpad forums. I sold the dual Xeon 900 MHz rig in 2010, now looking at buying it back 😀 S2DG2 supported only 2.8v CPU's though, I found a pair in ebay back then.

I'm sometimes very tempted to put my xg-dls 2x-900/2m 2gb on ebay. Just to see if it will sell. Then buy something nice for myself. It just sits on a shelf and I look at it wistfully every other day or so.

Boards I have or will have soon that are "Standard" ATX or EATX:

SGI M29A
Asus XG-DLS (with another on the way)
Freeway FW6400GX (I have two)
Intel MS440GX (Gateway OEM, limited to 550Mhz Xeons)
Intel SBT2 (NIB)
Supermicro S2DL3 (on the way)

Most of these are super rare. Also dick move on me for taking two of them off the market in the last week.

Supermicro S2DGE

C440GX+

MS440GX+ NIB
http://www.ebay.ca/itm/252179028087?_trksid=p … K%3AMEBIDX%3AIT

Best bet is the S2DGE for 900Mhz Xeons, but I'm assuming you have 2.8v Xeons right? 5/12v will not run on this board. C440GX+ is 5/12v also I believe. MS440GX+ should be capable of running 900Mhz 2.8v Xeons but the last bios for it I believe will only run 550Mhz Xeons max.

Can your Asus XG-DLS run 733Mhz ?

Thank you,

Matthias

100mhz fsb only. There are a few options for overclocking to 112fsb, but realistically, no.

A 733 "xeon" is just a regular pentium 3 in a bigger box anyway. Throw that away.

I ran a pair of 1Ghz procs at 112Mhz FSB for 840Mhz as a test. They're actually slower than 700Mhz 1MB or 2MB Xeons on 112Mhz FSB at 784Mhz.

I have Dell Precision 620 board with PSU and accessories (pretty much everything except the case), I am planning to get the board to run 2MB CPU's on 133 MHz bus (with lower multiplier). On Dell you set the CPU speed with floppy disk (utrility called sprfrq2.exe). It basically sets multiplier and the resulted speed cannot exceed rated CPU speed, otherwise the board wont' boot iirc. I had a complete 933 MHz Precision 620 once and experimented with it, though did not have 100 Mhz CPU's to test. But it had CPU speed option in BIOS ("Compatibility") which seems to be 100 MHz speed setting and on the board there is unsoldered jumper stating "100 Mhz" so it is possible that it works.
Though not sure I can get it to work at 133 Mhz FSB. I can live with 700 or 900 MHz CPU but I want it to work at 133 MHz bus speed 😀 100 MHz seems such a waste for that reat CPU.

Yeah, it was basically for OEMs to sell the upgrade parts at Xeon prices.

This is an Acer board. SGI put Acer boards in the whole Visual Workstation 230-330-530 line.

Well, the FSB 133 Xeons are just regular P3s, just smallest 256 KB L2, only dual CPU support (no quad/octa CPU support) as LuckyBob said. Also they are clock per clock slower, even slower than the older Tanner based P3 Xeons, idk if an FSB 133 P3 Xeon is slower clock per clock than the Pentium II Xeon as well

There are reports of Pentium III Xeon 900 outperfomring early Pentium 4 Xeons easily, a 900 Mhz P3 Xeon if i remember, could outperform an 1.7 GHz P4 Xeon.

I would not be surprised if that's the case. I may have to build an early P4 setup just to bench against my upcoming S2DL3 build, only problem is no AGP on that board so I'd need to compare using PCI vid cards.

MSI MS-6135

With this board there are VER1 and VER2 boards and I have a VER1 board with BIOS 62710 07/15/97 A6135MS V1.4 01/28/99 which AFAIK is the latest. The system currently has 2 x Intel Pentium II Xeon (Drake) 450MHz @ SL33U 1MB L2 cache 2.0 volt CPUs.

I just found 2 x Intel Pentium III Xeon (Cascades) 700MHz @ SL49P 2.8 volt 1MB L2 cache CPUs and am wondering if there is any chance I can get them to work in my MS-6135 VER1. I tried plugging them in, but the system failed to post.
