Anti-Aliasing Causes Texture Corruption On ATI X800GT?

[Gar1ndan]

alizee, i know, it's really strange isn't it! Same with me, only artifacts at 2x!

Is the algorithm a software thing? Cos if it was the drivers i would have thought there'd be other people but i can't seem to find much. Then again, i can't understand how it could be the hardware, but i'm no expert.

 

[Gar1ndan]

I have now tested the 5.11 Catalysts that came out yesterday, and theres no improvement

 

[Gar1ndan]

Have now sent a lengthy email to ATI so will see what they have to say.

 

[filho]

I will buy the new PSU and as soon as it gets in my hands i will test and post the results here.

 

[Gar1ndan]

Filho, its certainly going to benefit you having a better PSU (i originally put harddrive?? must be going mad) and the one you're getting looks to be a very good one. I still am not sure it will solve the problem though. I guess since you had the video error message on post aswell you might also need more power, but i'm not sure the texture corruption will go away. We will see i guess, you can be our test subject

 

[filho]

Well, my new PSU came today and guess what?

Its the same sh** .

BUT !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The guy who sold me the Video card told me to try something.
He said to reduce 50mhz at gpu and 50mhz at memory.
I tried that and the problem was gone......
He said this issue its most like from overclock, but noone of us did overclocking right?

I will do a few more tests to find the perfect mhz number.

U guys should try this too, reduce the mhz of core and of memory.

I will post more later.

PS - bad english with fast typing = LOL

 

[filho]

Well after some tests i have found the source of the problems.

Its memory overheating.
For some reason the memory clocks seem not to be apropriate .
Theres no need to change the Core mhz, keep it as it is (mine is 475 originally).

The memory clock of my X800gt was originally 350, ive reduced it to 300 and got no artifacts or texture corruption.
Ive tried 340, 330,320 and 310 and i had artifacts while testing.
So 300 at memory clock its appropriate.

While testing, i put my finger at the memory chips and they were very hot, so i suggest everyone who has this card to buy some kind of memory dissipator.


U need ATI tool to change the memory clocks, here its a screenshot of it:

Change the memory clock and then click "Set Clock", u need to click set clock or else the new clocks will not be applied.

U can download atitool here:

Gar1ndan and alisee, do as i did and reply here with the results.
Cya!!

*edit* from alizee (I posted from a friends computer and forgot to log out his account)

I've actually been running at 4xAA with no problems and acceptable framerates. It seems that on my card it only happens at 2x. really weird, it seems as though if it happened on the lowest it would happen even higher, neh? My monitor's highest resolution is 1280x960, so I'm not able to try 1600x1200 or anything.

Have you both tried 4xAA and had them same problems?

 

[Gar1ndan]

Glad to see the threads still going.

Filho, sorry to hear about the PSU, i did say i thought it wouldn't be that. See some people love to preach about stuff, like the guy who posted all the PSU stuff on the other forum, "your psu is no way near good enuff" and that sort of thing :roll:

Oh well. It is strange that your artifacts have gone away by reducing the memory clock, that kind of suggests maybe the memory is not really up to scratch, because we were all running at stock speeds and the speeds are set by sapphire, so i'd be a bit disgruntled if that was the problem. Maybe we should try and find out what the memory speeds on X800GTs are supposed to be? Find out what they are on X800GTs from other manufacturers?

Another thing Filho, do you have texture corruption at all levels now? Or is it just 2x AA?

Because yes Alizee, my texture corruption has always just been at 2x Anti-Aliasing as i said earlier, which is really strange isn't it.

Unless they are similar? And for some reason Sapphire push their memory, and something to do with 2x AA is causing it to be pushed too far? I don't know, is definately a strange one. But we can try clocking the memory back to see what happens anyway? I'll try soon.

Filho, did you now you can also use the sapphire trixx utility to adjust your cards clock speeds? Doesn't matter, ATI Tool is a good program anyway, just thought i'd mention it.

Edit: I'm trying to look into clock speeds for X800GTs. It seems that 475 for the core is the default on most cards, but as far as memory clocks, i cant really find another 128Mb one. The 256Mb cards differ quite a bit (obviously with different ram) with some cards going as high as 1000MHz. Our 128Mb card is 700 (350x2 'DDR'). On the 256Mb cards that have higher memory clocks both the powercolor and sapphire run at 980. But one thing is easy to find, everywhere says the Sapphire X800GT 128Mb runs at 700, so its not some odd error with the settings, loads of places have reviewed the cards and didnt seem to have a problem, so we should be able to run at that speed aswell.

Filho, i've yet to test my card, but if you really have to run at 300 to get your card to perform then you are definately due a refund, because the card is advertised and sold as 350.

Updating....

The problem persists even with 300 at memo.

And i tried to use a VERY BIG fan pointing to videocard while playing.
The memory were not hot, i put my finger and it was ok.

So the memory overheating is discarded.

And i think thats the end of it.....i will RMA the card....

 

[Gar1ndan]

Yeah Well i had to send a problem report with loads of system info to ATI 2 days ago, so hopefully they'll have something to say soon.

Hey guys,i am experiencing the same problem, my specs are:
amd sempron 3000+
1 gb ram twinmos
sapphire ati radeon x800gt
asus k8n4-e deluxe
i asume that we all 3 have faulty video cards, wich would be the worst case or something else,but i have no idea what can it be,however, i experience these arftifacts in "farcry" , "wolfenstein et", "battlefield vietnam",and some more 3d games.
I get those artifacts mostly after few minutes of play,but i found a solution to get them out for few mins:
when they start appering i just change the resolution and they disapear for few mins,but then they appear again.
i rely on u guys to solve that prob,i dont have much knowledge in this.
good luck!
by the way did u noticed we all 3 use mobos with nforce4 chipset?

 

[alizee]

porov, which resolutions do you recieve it at and what AA level?

 

[xtknight]

AA is more intensive thus it's probably a graphics card overheating or underpowering problem. Maybe some issue with a specific part of your board.

Edit: lol, duhhh, should have read the thread. BTW even if it isn't overheating, the mem chips themselves may just be faulty or maybe scorched from prior heat.

 

[filho]

The only solution i see is RMA and i hope that when i receive another x800gt from sapphire i dont get the same issues just because of some kind of incompatibility with Asus boards or nforce.

 

[xtknight]

I really doubt it's an incompatiblity issue. It's almost certainly an ineptness of the onboard memory chips.

 

[porov]

OK Guys apperantly it looks like it is a faulty video memory or just a card problem,but we cant be 100% sure,some one of u has to return his card and get a new one and then see if it fixes the prob, because it is possible that there is incopatibility between the mobo and the card,and in that case we have just too look for a new card.
so i am waiting for u guys(i cant return mines at the moment)

 

[filho]

Can anyone here test the card with another motherboard? Like a friend of yours or something, to see if its incompatibility or not?
Test with a non asus board.

 

[Gar1ndan]

Well i had a response from ATI and it wasn't helpful at all!!! Apparently the Sapphire X800GT is "not certified by ATI"!!!!!!!!!! Whats all that about! It wasn't on there list when filing a support ticket, as well as quite a few other Sapphire cards, and apparently thats because it's not an official card as such!!! So we are not going to get any support from ATI!!! What a load of rubbish! And i've still heard nothing from Sapphire!

I suggest we all start emailing Sapphire, with the same problem, and all link to the Sapphire thread Problem With Batch Of Sapphire X800GT's??? , and we'll make them look at it! lol

Here's the full reply from ATI -
"The card that you have is not certified by ATI. This is why it is not in any of our selection lists. If this is happening in the same way with alot of users that have this card, because it is not certified by ATI, it would need to be looked at and fixed by Sapphire "

 

[porov]

Those bastards from saphire,i never trusted them,they must've messed up something with the card(maybe thats why the price of the card is so low).It is wether a general card problem or just a incompatibility.Anyway they ARE RESPONSIBLE FOR THIS,WE REALLY SHOULD EMAIL THEM AND TELL THEM ABOUT THE PROBLEM.

 

[filho]

If everyone sends an support ticketo for sapphire, maybe they will say something or maybe release a bios update for the card.
Ive already sent one support ticket, do the same.

 

[Gar1ndan]

Yeah ive sent two to Sapphire now :roll:

 

[kirkcan]

I too am having the same graphics problem. I've been searching for answers all over the net. I bought a $700 ATI video card and I get weird textures in BF2. Sometimes if I alt tab out and back in, the glitches go away.

Usually the texture distortions are rectangles that appear all over but when I go to weapon zoom the view is obliterated by these rectangles.The game text is all pixelated.

I've been advised that my power source is too low for the card but its a 400mhz source.

here are my specs
AMD 64 3200 processor
2Gigs RAM

ATI Radeon X850XT
256MB
smartgart set to 8X
3D settings= Direct3D

Catalyst Drivers version 6.14.10.6542
Directx 9.0c

1024 x 768 70mhz refresh
Windows XP



BF Game Settings
1024x768 @70hz refresh
all terrain,texture,dynamic shadows set to medium

anti alaising set to 4x
texture filtering set to medium

This is extremely frustrating. I've tried to reinstall the catalyst drivers. even went back to the older version. I've tried all different settings of the AA and still no luck. I didnt have these problems with HL2or anyother game just BF2.


Any ideas?

Thanks

 

[porov]

hmm that is taking too long ist it,did u get any response from sapthire about the problem?

 

[FallenDeity]

I'm having this problem myself, and I swear to god, if someone else says overheat, im going to beat them.

System specs: yeah, you're not going to beleive this, but..this might be a good thing.

Gigabyte GA7AXP old faithful..well, when I put a new NB fan on.. :X
AMD Athlon 1800+ (fried previous processor..SiSandra owns another processor)
WD "Caviar" 80gb x2 raid 1 usual speed 8mb cache
WD "Best buy special" 80gb 8mb cache..rather old drive
3GB (3x1gb) off brand PC2700 ram newish
And of course, Sapphire ATi Radieon X800GT AGP just got it a couple weeks ago


Isnt isolated to just PCI-E.
I wanted to "finish" this computer, install hardware to the maximum (but useable) capiblites, for she will be my bedroom box, till I get my intel box running, then she'll become a server..untill it dies.


NOW!

For some things that DID help.

I quit using max resolution. And upped the refresh to 85hz. I get "tearing' every so often, but alt-tab kills it. But no more matrix like green crap all over my screen. installed new BIOS, stopped the #132 errors..woohoo, most likely was a conflict with my ram.

I can run CS and WoW without any game hindering tearing, with max settings, just have it at 1024x768 85hz. Still pissed off tho, I bought a good mid/high end card, I shouldint have to "turn settings down" to play my games. Im gonna RMA this sob anyhow.. I don't like how Sapphire has been treating me, or any of you folks.

Fallendeity - aim.
