HELP - 8800GTS 512MB

[vlad1966]

Am I the only one with this problem?

 

See sig for my system. My 8800GTS 512MB vid card is giving me fits!

about every 3 or 4 times I boot my hack, the graphics are all scrambled,

so I have to reboot. This usually clears it up on the 2nd reboot but not always.

 

What I've tried so far:

 

10.5.1

10.5.2

10.5.2 + Graphics update

All of above plus editing the info.plist with:

 

<key>IOPCIPrimaryMatch</key>

<string>0x060010de</string>

 

for the following kexts:

GeForce

NVDANV50Hal

NVDAResman

NVinject

 

Non of this seems to help.

 

I've also tried putting together a string for com.apple.Boot.plist

but haven't been able to do it with the instructions found on this

site or netkas.org.

 

I'm starting to wish I had bought a Radeon HD3870 instead.

 

Can someone provide a string for the 8800GTS 512MB G92?

Before I do something crazy, like go buy a Mac Pro which I can't afford.

 

This hacking is really getting old.

You need to isolate the problem.

 

Does it do this under windows or another OS?

 

Yes - then one of your pipelines could be toast. Umm.. the fan is running on the card, right? Seriously, sometimes it happens. If it's running what is the card temp (if you have time to check it)? Hopefully the card is under a warrenty of some kind.

No - there is some sort of issue with 512MB cards, but I'm not that familiar with it since I don't have one. Maybe search the forum with that?

 

If you've had this card running fine under another OS for quite a while and suddenly it does this when you try using Mac OS, I'd doubt it's the card... unless you exchanged some hardware in the case and maybe something happened to the card then.

 

Hope you figure it out.

I don't think it's a hardware problem with the card.

I've had XP & Vista on this computer without a single problem.

The fan on the card is ruuning.

I only have this problem with OS X.

Sounds like the card is okay then.

 

Are there any firmware updates for the card or the board? Doesn't hurt to do those before you go too in-depth with the problem, unless someone else has an idea. I've not used/seen a PNY card with any issues. Anyone else have a 512MB PNY card working in their machine?

Could be something with a frequency problem, maybe flashing the ROM with the one from a better supported model would help.

However if you do this, be carefull and know what you do.

Windows rely on software and ROM for frequencies adjusting, whereas mac is purely ROM based.

[vlad1966]

I don't think flashing the ROM is the answer - anybody else?

[vlad1966]

{censored}. I thought putting a graphics string into com.apple.Boot.plist would help,

but I'm still getting the graphics corruption about every 4th or 5th reboot.

It's REALLY Annoying. This is the plist template I used to get the grpahics string:

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Any recommendations?

I'm considering selling the 8800GTS & buying a Radeon 3870, though those too seem to have issues.

imo your card is faulty. Perhaps you didn't notice on windows but it should work on OSX.

 

I know, I have a G92 GT which is the same and it works 100% as on a MacPro.

if you want the mac pro gfx string, check my post, i posted it on the G92 gfx string thread.
