<=44.96 causes heavy 2D artefacts, FX5900
 
hi,
with 44.96 <= I get the wierdest thing happening: namely, if I fire up ANY OpenGL app, I don't have any 2D artifacts in windows/Xfree(in Linux). With any post 44.96 I have artifacts happening even if I start an OpenGL app, both in X/Windows and in OpenGL/Direct3D windowed/fullscreen. Wtf is going on?

System conf:
Asus A7N8X-Deluxe (Nforce2 3.13 drivers) mobo
AMD Barton 2500XP (Oclocked to 3200XP, with artifacts happening on both oclocked and not oclocked system processor setup)
Kingston ram 2x512 modules running at 200Mhz FSB (same as the processor), with all other stuff left to STD (the artifacts happen with all kinds of bios oclocking setups, and even underclocking the FSBs to 166Mhz).
2 Sata drives
Intel e1000pro 1000mbit LAN pci card
LFS (Linux from scratch system, gcc-3.2, Xfree 4.3 Kernel-2.6.5)
Windoze XP pro
Prolink Pixelview GeForce 5900 w/256 RAM not EVER over/underclocked

Please please, if anyone has any constrictive suggestions as to where to look for problems fire it away, thanx.

Another thing worth mentioning, with any post 44.96 I have artifacts in OpenGL applications such as Alias Maya 5.01 in the viewport, namely the tessalation polys are periodically rendered as black, and the 'Maya Hardware Render' causes the machine to hange (both in Windoze and Linux).

try the 53.36 drivers and see how they work.

I did, same thing :(..

Have you tried using different nvapg settings?, see the nvidia readme for it. If it happens in both OS's then your looking at a hardware issue and maybe pre gfx card failure.

It's a "known" problem that was fixed sometime between 4496 and 5328.
use a newer driver

As I said, with ANY (meaning I tried ALL of them) post 44.96 ('post' meaning 'comming after')I have the same artifacts, the only difference is that it is even worse since I can't make a workaround of having some openGL program running (it works even if the program is minimized into a miniicon, or tray or what have you).

"Have you tried using different nvapg settings?, see the nvidia readme for it. If it happens in both OS's then your looking at a hardware issue and maybe pre gfx card failure."

Yes I have tried all kinds of combinations. With 44.96, I cannot get the Nvidia AGP (the one that commes in if you check Nvidia AGP support in the Linux kernel configuration) to work, only the NvAGP from the driver. With NvAGP, I cannot get 'fast writes' to work, whereas if I use a newer artifact-making driver I can sucessfully get the Nvidia AGP for Nforce chip to load, I do get fast writes (I cat /proc/driver/nvidia/status to see if its up or not btw), but the horible artifacts are happening all over, eventually causing X to freez (I am however able to ssh into a machine from another box, and even kill and restart X but the virtual terminals are gone forever once it freezes..).
I'm beginning to think that my card is actually faulty in hardware (though everything works perfect with 44.96 and an openGL app running).

OK, got this issue figured out in Windows XP by downlclocking the driver's core processor speed from the default 400mhz to 360mhz (with memory left at the default 800mhz)... The good thing is that nvidia driver itself autodetected a 426mhz processor/982mhz memory for the 'Performance 3D' mode, meaning full-screen OpenGL/Direct3D games in windows, and it works, games are stable, aa works great etc. The question is: how should I go around _downclocking_ the clock speed of the GPU in Linux? I saw a tool called nvclock (or something like that) while googling, but they were saying it didn't work with FX5900 series, or worked but faulty and buggy... Any suggestions guys? Tx.

ander, you and I are in quite the same boat. I noticed when I first got my FX5600 Ultra that it was *made* overclocked. I have to reduce both my default core and memory speeds for it to be stable. See this thread about nvclock:

http://www.nvnews.net/vbulletin/showthread.php?p=329288

The newest NVClock build will "support" your card - I use the term loosely since it doesn't quite work with mine. If I change the memory speed, everything turns to poop.

http://cvs.sourceforge.net/viewcvs.p...clock/#dirlist

Since I've been through the rigamaroll with this, if you have a question regarding configuration, I may be able to help.

Happy Hunting,
Kahnmark
