Try a slot 1 proc with 133 fsb see if that runs stable, maybe the slotcket pin moded tualatin combination is the cause for instability.

Which motherboard is it? Can you change chipset voltage?
Maybe add a chipset cooler.

Underclock the ti4600 a bit and see how that goes, or try another Geforce 4. Not every card runs well at 89mhz.

Was afraid someone was going to mention that. I don't think I have any slot one procs with 133Mhz FSB. Perhaps I can scrounge up a Socket 370, 133 Mhz FSB chip to throw in the slocket and try it instead.

It's an Asus P3B-F running the latest BIOS. I think this is the only AGP 4X GF4 card I have. I have a Ti4200-8x and Ti4400-8X - would those work at AGX 2x speeds?

How about a pentium 3 450mhz ? that 1 should run at 133 fsb without any problems.

If the agp 8x cards work on a 2x board you can try them.

Slotket adapters can cause instability too, you need a good one for a tualatin.

I'll give it a shot... this Asus one is pretty popular.

There aren't a lot of video cards that can handle an overclocked AGP slot.

If you're running a Tualatin, then you would be better off putting it in a late socket 370 motherboard like the Asus TUSL2 than in a slotket adapter . I have 1.4ghz Tualerons (I had to use Tualerons because the 1.4ghz P-III's I bought wouldn't run full speed because the Dell BIOS doesn't support 133mhz bus) in two Dell GX1 machines with the BX chipset, but fortunately with those I don't have an AGP slot to worry about. I have Sparkle 9500GT PCI cards in those and will probably even replace those with GT430's when I find a couple of them cheap enough. They are quieter and draw less power. i815 is a much better chipset for full Tualatin support.

You're going to need something like the Powerleap PL-iP3/T. The T at the end is very important as it distinguishes an adapter designed for the Tualatin from one designed for a Coppermine. Upgradeware also made the Slot-T specifically for Tualatins. A generic slotket adapter most likely won't work properly.

If all else fails, you could get a Celeron Tualatin 1.4 and if you desire a little more speed, you could crank the FSB up to 124MHz which seems to work fine 😉.

I'm going to reply here and say that it may not be the AGP bus that is the problem here.

There are other possibilites. You just gotta go through them one at the time to find the culprit. Some of these has been mentioned before.

- Do the video card work in other systems in 3Dmark?
- Try another CPU at 133 mhz (Pentium III slot 1)
- Try another memory stick
- Try a PCI video card

My personal experience is total opposite the one sliderider is telling, and that is that most cards do work at 89mhz AGP.

The CPU is modded so it will work in a FCPGA slotklet (coppermine). The Powerleap adapter will do both CPU power conversion and pin alignment, while the upgradeware one only do pin alignment, meaning you will need a board that supports the Tualatin voltage. The P3B-F supports the required voltage.

I've tested both the Powerleap PL-iP3/T and my modded CPU in my P3B-F. There is no difference in terms of performance/stability or how the BIOS recognizes the CPU.

133MHz mod definitely works on 440BX -> http://tipperlinne.com/p2bmod.htm

Well folks... it seems like it may be video card related. I swapped out the purple PNY ti4600 with an EVGA Ti4600 (128-A4-NV82-S1) and immediately saw artifacting upon entering Windows. This card works fine in other systems.

I pulled it, and then swapped it with a Gainward ti4800SE 128MB card and observed the same lockups during 3DMark 2001 SE benching.

I pulled this card and finally switched to a Leadtek Winfast A280 (another Ti4800 SE) and observed NONE of these issues - smooth as silk when running at 1.4Ghz/133Mhz FSB/89Mhz AGP.

Switching to this card lowered my 3DMark score to 7511 (from 8474 when using the Ti4600 @ 1.3Ghz). I guess this makes sense since a 4800SE is basically a Ti4400 with AGP 8X support.

Quick question on that Leadtek card, is that Mold, a hornet's nest or just dirt in those fans? Because I dont see fanblades. I just see some strange material similar to shag carpet.

I bet these are air filters full of dust.

Yes, they are air filters that are in dire need of compressed air.
