Oh windows Me allows the same system file tweaks for cache and larger memory support. as 98SE (for above 256mb ram)
I beleive what the 6600 is best for the pentium 4 socket 478 are the codename Prescott and yes it can run windows 7 64bit thus it oould run probably windows 10 64bit and linux that the platform is available in 8x AGP MODE although earlier pentium 4's on that platform are fine; anything single core socket 775 should have no issues with windows 9x (non pcie)
Prescott not optimal for 9x but greater with dual boot for a 64bit secondary OS on same computer and may be interesting to trial 9x in a hypervisor.
The cpu driver from xp x86 can be put in place of the cpu driver in 98se and millennium for better pentium 4 efficiency.
I haven't tried the pentium 3 one.

What chipset did that give you trouble on?

Intel 440BX.

I tried this again on my 440BX but with a Tualatin with Windows XP. Both driver version 81.98 and 175.19 installed and recognized the card but attempting to run anything OpenGL or DirectX would just lock up the system.

I tried it on Windows ME again and the whole desktop was corrupted. I don't remember what combination of hardware I was using previously but it's not stable at all on this hardware.

ASUS P2B with Pentium 3 for SSE and driver version 175.19 with GeForce 6600 AGP.

Dawn is here to haunt your dreams.

Success! I managed to get it working with driver version 71.84 on Windows XP with a 440BX chipset.

A CPU with SSE such as Pentium 3 or better must be used for shader effects. For example, the FX Dawn demo will crash on an early Celeron without SSE and 3DMark2001 will show significant corruption like in the examples I provided at the start of this thread.

There are still some graphical glitches and corruption when running 3DMark2001 even with SSE. Older DirectX interfaces seem to work alright but seem to be slower than older cards with their accompanying older drivers.

Sounds like you have a bad card.

Run Video Memory Stress test from the Heron's boot cd set of utilities and see if the memory actually tests OK?

I have a 6600GT PCI which has a bit of bad memory I think. Probably should chuck it.

Thank you for the advice. I've got Video Memory Stress test running to validate.

why won't that fairy turn around 🤣
memory test usually brings old memory back to life sometimes.

The memory tested fine. This corruption and incompatibility is due to some other issue.

You've probably already eliminated this as it's basic, but did you ensure the clock speeds were correct? I've heard of folks buying old cards that had aggressive overclocks or other custom stuff done to them.

Testing now a 6200 agp bios moded to 6600 specs with 71.84 driver and windows me on a 754 SIS motherboard and I'm not having a lot of problems, found some glitches on nfs underground 1 and 2 not afecting the gameplay, tried eRacer and it is unplayable.Games tested ok:Swkotor, Undying,Nolf 2, Max payne and Joan of arc until now, and of couse 3dmark 2001.

I consistently have issues with GeForce 3 and up with shader enabled games and other software in Windows 98 and older chipsets. There are always serious problems whenever SSE is missing as well.

The latest official driver 81.98 is always the worse. 71.84 is only the first one I encountered whole working backwards where Dawn would run properly.

I tested this same GeForce 6600 with a Coppermine Pentium 3 (Slot 1) on a motherboard with an Intel 820 chipset and it works flawlessly. Whatever the problem is with the 6000 series it appears to be limited to the older 440BX and earlier Intel chipsets.

Now, what people don't realize is that GeForce 6xxx support in Win98/Me is very dependent on the motherboard/platform you have, that's why it can work a bit better for some people when all the stars align.

😀

To be fair, nobody in their right mind would've used a GeForce 6xxx series GPU from 2004 on a platform that was launched in 1998. For those who remember those times... 6 years was basically a lifetime. Your new, bleeding edge PC, was already obsolete in 1 - 2 years. 😀 And by obsolete I actually mean that games would sometimes completely refuse to run on it.

I upgraded from a very early Pentium 2 to a Pentium 4 back in the day so I guess I missed out on all of the compatibility roulette between. I don't remember ever having hardware fail to work as expected prior to and after the Pentium 3 era. Maybe I just got lucky?

It wasn't until I got into retro collecting where I found that the Slot 1 "sweet spot" is actually a compatibility hell. Because I had such a different first hand experience, I'm always surprised at how difficult it can be to find the correct combination of parts to make a stable system.

I ran my 6600 based winfast GT on my dual P3 with winxp it wasn't the best 😀
I actually put a SiS 315 in it instead and now that p3 system is snappier 🤣
So I'm putting the 6600 GT into a socket 475 Prescott running @ 3.4ghz see if it bungs up I am suspicious due to seen artifacts but windows 7 may be the saviour.
As soon as the gpu started 3d it would bung up only like opengl stuff these things so old now.
One thing people forget is card manufacturers did update bios for newer windows versions too so they moved away from older generation stuff so we can buy these cards and they run better on NT than DOS windows by bios version.
ATI cards notorious for that though only I own PCIE versions. BIOS can be downgraded most of the time though nvidia is more obscure than ATI.
Worse is i can't find any bioses or bios updaters for anything AGP generation thus i can only assume thats because many gamers never went that far in gAming performance as they do now with PCIE.

I saw this thread just now, that I own a 6600 AGP.

For me the situation is good, with a Nforce 2 Ultra chipset, an Athlon xp-m CPU, and Windows XP.

I am using the Forceware 91.67 drivers.

Ps: the only thing I have a Peak edition that runs at 300mhz core, and only 200 DDR ram, absolutely bad.

When I try to overclock the GPU doesn't go over 320mhz and the RAM 235mhz. I think could be drivers limit, sort of that.
