This is a little like mine in the works: Tualatin 1.2ghz/Intel D815EEA2/512mb/Quadro4 900XGL/SB Live! - just gotta find a case, ebay prices are nuts!

This machine has been such a pain in the butt.

Well I finally got around to taking some pics today, after lots of testing I've reached the conclusion that the combo of this motherboard and powerleap adaptor will NOT run at 133mhz fsb.

P3 1.0 (133fsb) runs fine at 133mhz and 100mhz (no powerleap)
P3 1.4 runs fine at 100mhz (1050mhz speed), keyboard stops working after a few seconds at 133mhz.
2 x Celeron 1.2 run fine at 100mhz but when overclocked to 1600mhz, you guessed it the keyboard stops working.

I'm going to set this thing to the side for now, so annoyed.

edit - attached some pics.

You are not the first one, please see FB Marketplace Gateway Rebuild - Beginner Build Log! and specifically page 2 for more info.

If only I'd seen this thread first! At least I'm not crazy!

Thank you.

Well I just ordered a CUBX on ebay. Comes with an interesting CPU, 1.13ghz Celeron.

Hopefully this V3 is happy running on an 89mhz agp bus speed.

Which Powerleap adapter are you using? Is the CUV4X able to provide the correct voltage if the Powerleap is not actively regulating the voltage itself?

PL-Neo/T is the model.

In the bios it's reporting 1.5V. Everything is fine at 100mhz fsb on Tualatin processors but at 133mhz the keyboard stops working whether it's usb or ps/2. The clock continues to move ahead if you're on that screen in the bios though. This issue occurs with the fsb jumper on the Powerleap in either the 100mhz or 133mhz position.

Are all caps ok? I am in no way an expert, but the power draw at 1,5 instead of 1,75 might stress the rail more than it would like. The PL-Neo/T is, imho, like the Lin Lin adapter, just telling the MB how much Vcore it wants, and making sure the necessary bridges are connected to have the Tualatin be discovered correctly.

I've tried literally every selectable voltage with one of the celeron processors, nothing improves the situation.

All caps are visually mint condition.

I've already torn it down and put the board into storage, I'll probably sell it on eBay with a couple 512mb modules and a P3 1ghz Copermine.

So I ordered a CUBX on ebay for $99 Canadian.

Shortly after clicking buy it now I got a message from the seller saying for some reason it would take 6-8 days for payment to clear from paypal which was too long for him. So he cancelled the order, of course a couple of days later Paypal takes the $99 anyway. A week later after calling them and my bank I have the money back and no motherboard. I suspect this guy probably just sold it locally or noticed how much more they go for on ebay and decided to kill the deal.

Ah well, anyway I've just now ordered a TUV4X instead, hopefully a board with official Tualatin support will work out better. 🤣

TUV4X owner here. In my case, I have been able to overclock my system up to 155MHz in BIOS. Anything higher would cause the keyboard to stop working, so in order to circumvent that, I push the FSB higher with SetFSB in Windows.

Make sure your RAM can tolerate the overclock. I have six ECC sticks which run fine at 166 MHz but out of these six, only two CL3 sticks run completely stable at 166MHz 2-2-2-5 and require ECC mode to be disabled or else there might be issues with the hard drive.

Also, make sure you disable CPU DRAM Back to Back Transaction in BIOS, or else the system will freeze before attempting to boot the OS, unless you use a Promise SATA300 TX2.

Wow those are huge fsb numbers!

All I'm shooting for right now is stability at 133mhz fsb which the CUV4X couldn't do with any of my Tualatin processors and the powerleap adaptor.

The CUV4X is not just a TUV4X without Tualatin support... Perhaps your VRMs aren't up to the task and so they are just too weak to run your Tually at the proper frequency, I don't know as I never owned a CUV4X, but I owned an MSI 6309 v2 which was Coppermine only and required a pin-modded Tually and a custom BIOS in order to support it, and even though I did that, it was not 100% stable, unlike when I ran it with the 1000B Coppermine (1GHz, 133MHz FSB).

On the other hand, on my TUV4X, 166MHz works but it's a little unstable, giving issues mostly with 3DMark 2003 complaining about corrupted textures. Just reducing the FSB to 165Mhz though, makes it run stable even without ECC mode enabled, but as a safety measure I'm running the CPU with the highest vCore supported, 1.75v, and doesn't heat up a lot, idling at 43/45°C with my Cooler Master Jet 7+ running at full speed.

I'm still experimenting in order to find the "sweet spot" between stability and performance though.

EDIT: 163Mhz seems to be the sweet spot without ECC mode enabled. Super stable, but needs the vCore to be set to 1.75v or else Windows would soft freeze at boot sometimes.

EDIT 2: I managed to stabilize the machine at 166MHz FSB and the vCore at 1.6V. All I had to do was to update the SATA controller drivers. At 167MHz the ECC begins to fail so 166Mhz is the maximum limit on my machine, although it seems that only the RAM is holding me back.

Well the TUV4X has arrived and I finally have a reliable Tualatin machine for the first time in many years.

One interesting quirk I've noticed with this board though is if I disable the onboard audio in the bios 98se stops booting. Turn it back on and everything is fine. Who knows why, updated the bios, reset to defaults, etc. Will NOT boot with the audio turned off. No big deal in the end I just haven't installed the drivers for it and am using an SB Live anyway.

Strange, i have a TUV4X and works fine, but it's also true mine lacks the onboard sound card. Also make sure to disable CPU to DRAM back to back transaction. It's a very picky feature.

Instability at higher frequency's (and higher powerdraws) can also be a sign of our old nemesis: Bad Caps.
ASUS boards seems to be more resistant to this, but are certainly not immune.

Hi,

are there any Tualatin boards with an ISA slot?

Via 694T-based mainboards often have one ISA and should be natively Tualatin-compatible.

Intel 815e lacks ISA support, so you if any (industrial) mainboard has an i815e + ISA, it's using an extra bridge chip, I presume.

My SIS-based Tualatin DDR/SDRam board does not have ISA, nor does the ServerWorks based Supermicro board have any.
