Is it like a checkerboard pattern?
Sorry I didn't answer this already. No, no checkerboard pattern, just the "black seam" in certain quake maps. I have checked around at quake3world forums and I am not only radeon owner with this problem. It occurs because it has something to do with ATI's strick adherence to OpenGL specs whereby certain maps that aren't made properly have this effect (even though it's occuring with a few stock maps -- go figure?). Another guy says he only sees it in add-on maps, which makes sense, but I insist that it's on a few "official" maps as well.
Anyway, I feel that I have a genuine 9800np; however, something isn't quite right:
I am confused about the P/N because I can see two. One is on the card itself (not a sticker on the card). It is PN 109-A07500-00, which I beleive denotes a Sapphire build, according to this reveiw
(check the last paragraph on the page, and the bottom pic on the right shows exactly what I see on mine).
The other P/N is found on a sticker on the card; it's the one I listed earlier in this post (102A0751301081342).
But the retail box says "Build by ATI". And if you look here
you will see that all "Built by ATI" P/Ns begin with a 102 and have NO LETTERS. So consider the first P/N I gave you (102A0751301081342). It has the letter "A" in it, which is specifically stated at the link above to be a card by a 3rd party.
It appears as though this was a Sapphire that was pawned to me as a retail card. The box has definitely been opened, no question about that, but all cables and manuels are present, and the card appears in good condition. What's more confusing is that the manual came sealed in a bag that has a sticker (on the bag) with the S/N and this serial matches the sticker's S/N found on the card (the same sticker with the P/N 102A.....).
Also, the sticker on the bag says "Important: This is your unique ATI CustomerCare Product Serial Number. Affix it to your Getting Started Guide. Please register your product online to recieve full warranty and product support".
So what's wrong with this picture?
=Box reads "Built by ATI" not "Powered by ATI"; has definitely been opened.
=2 P/Ns both which point to 3rd party builder, although they do not match each other.
=2 serials that match; 1 on sticker on the card, the other on plastic bag containing the manual.
The only thing I feel certain about is that this is not "Built by ATI", which means no 3 year warranty.
EDIT/ btw, I have Infineon 3.0ns memory.
