charlie22911 Posted January 3, 2007 Posted January 3, 2007 i have noticed that on all x19XX series boards that follow ATI's reference design, there is a 3 pin connector near the PCIe power connector. (photo with jumpers in question circled) i have searched Google so much the text on their search button is worn off. my question is; what is that 3pin doodads purpose? i also found a dip switch with 2 switches in it, its supposedly for video region coding (NTSC, PAL etc). Thanks for your help, Charlie. Quote Share this post Link to post Share on other sites More sharing options...
Thraxz Posted January 3, 2007 Posted January 3, 2007 I tried a fan on it earlier today... It didn't work. Funny that you should post this now. Quote Share this post Link to post Share on other sites More sharing options...
charlie22911 Posted January 3, 2007 Posted January 3, 2007 yeah, i was thinking that too about the fan... but scared to try it, im not ready to fry this baby yet . maybe its a feature connector of some sort? think it may have something to do with HDCP? i cant even find a data sheet on this thing .

Nightshadow Posted January 3, 2007 Posted January 3, 2007 I've wondered what that was for as well. Quote Share this post Link to post Share on other sites More sharing options...
charlie22911 Posted January 3, 2007 Posted January 3, 2007 im going to breakout the DMM today and see how much voltage it outputs... maybe it has something to do with vivo? Quote Share this post Link to post Share on other sites More sharing options...
lackobreath Posted January 4, 2007 Posted January 4, 2007 I had noticed this before as well. I took a look at mine to see if it had a label and indeed, I see JU7 on it. Some searching over at XS brought me this: http://www.xtremesystems.org/forums/showth...2&highlight=ju7 For what it's worth, they couldn't make sense of it either. Google doesn't bring up much on ATi JU7 or x1900 JU7 either, lots of foreign language stuff. You may try hitting a few more tech forums JU7 in your search terms.

WintersFury Posted January 4, 2007 Posted January 4, 2007 My x1600Pro has a 3 pin jumper block on it. But unlike your pics it is jumpered. No idea what it does and I'm not sure I want to play around with it. I used to think it was fan speed on my card since it doesn't have a temp sensor, but an x1900 would... But yours don't have jumpers either... Who knows. Quote Share this post Link to post Share on other sites More sharing options...
charlie22911 Posted January 4, 2007 Posted January 4, 2007 VERY interesting! hmm... who is willing to ship me a replacment if i try adding a jumper . im going to do more searching, i hope something turns up as it seems to bug everyone .

barbz Posted January 4, 2007 Posted January 4, 2007 ill confirm this tonight but i tried to look for this set of pins on my x1950xtx and couldnt see it..... Quote Share this post Link to post Share on other sites More sharing options...
uneedav8 Posted January 4, 2007 Posted January 4, 2007 PAL / NTSC selector but they are usually labeled....... Quote Share this post Link to post Share on other sites More sharing options...
charlie22911 Posted January 4, 2007 Posted January 4, 2007 uneedav8, we know thats on the back side of the card near where the core is. the 3 pins we are refering to are near the FET's heatsink and the PCIe power connector. i searched through all of 2 pages of googles results, and lackobreath is right, most are in foreign languages that are not worth crap once translated... guess its time to search for a data sheet (is such a thing exists).

schoolslave Posted January 4, 2007 Posted January 4, 2007 I'm pretty sure that JU7 is a factory test jumper connector, so you can't do anything with it. I've dropped a mail to my contact at ATI and am waiting confirmation of this - but i'm pretty sure it's what they hook the card up to their test rigs with to check voltages etc before passing QC and getting packaged. http://www.sapphiretech.com/en/forums/printthread.php?t=7725 Quote Share this post Link to post Share on other sites More sharing options...
