ok this issue has been doing my head in for months on end.
I figured out a work arround but i want to fix it..
now any of you that ever overclocked a hd 57xx card will recognize the issue as a powerplay problem. But none of the fixes have worked.
basically when the card is in 2d mode i get rediculous tearing. some may call it artifacts, but its not.
the best way to describe it is to imagine the screen as a series of horizontal lines, which are then split in to vertical columns.
In 2 d mode these lines get all mixed up so what should be in the middle left flicker over to the bottom right (or some other random location) and they do that constantly. "pretty much exactly the same as the 57xx cards did when you over clocked them due to 2d clocks being too low"
i have changed 2d clocks. i have under clocked the card. i have over clocked the card, i have forced a set voltage. "did this with software and a number of hex edited bioses (some one was kind enough to edit them for me)"
Nothing fixed it.
2 things i found that work as a work arround are.
1. open msi kombustor stress test open gl death triangle in 120 x 240. and just leave it off the side of the screen where its not noticeable so card is in 3d mode but only just "with those settings the card is barley stressed at all but it is put in to 3d mode.
2. (only works with a digital flat pannel via dvi, and not a vga iput display)
Set the monitor to tv resolution 1080 Interlaced 60fps. (really 30fps x 2)
in interlaced mode it works fine with 2d clocks.
now 3d games are fine because its in 3d mode.
The reason i want to fix it now is because my old monitor died so i had to use one of my 1080p monitors i had spare. this monitor is a flat pannel but only had vga. so i cannot force it in to 1080i through ccc.
I tried that monitor overclocking tool. but i dont think the monitor supports interlaced mode either as it gets garbled..
i could get a second 7850 for xfire which would fix it im sure. but 2x 7850's is so over kill for a server its not even funny.
any idea what it could be?
mosfet/cap resister needs replacing? (i am perfectly capable of replacing smd components if some one can convince me that it is something like that)
Any ideas are welcome.
this is not really an emergency. as it is just the server system "all it really does is host assetto corsa and l4d2"
2x xeon c2q, 32gb ram la dee daa windows 7 x 64 for easy set up. and the afore mentioned hd 7850.
