SLI bridge lost!?!?

[meewog]

I have 2 gtx 275's in SLI. A message came on today saying that the SLI bridge is missing. Out of cuiousity I opened my case to see it actualy was missing. I doubt if I have removed it, because I would have remembered, but back to the point: it was no where to be found. At the moment I have a crossfire bridge and a 3way SLI bridge, my question is if I can use either of these to connect the 2 cards. As a guess the 3way should work fine, right?

another thing that is bugging me is that speedfan doesn't give any temperature readings on the graphics cards, this happened after I installed 190.56 beta drivers, I reverted back to 19.3x? something, but I still have no temperature readings. Anye ideas what is happening?

With thanks

try reinstalling speedfan, maybe the driver install corrupted it

three way sli bridge should work as long as the bridge fits in your case

tried that already. also nvidia control panel doesnt read the temperature readings. Thanks for the first post by the way

I really don't understand how you had a bridge in the first place and now it dissapeared...... Anyways if the three way does not work for you, you can get one off ebay for less than 2.99$

As far as speedfan goes, if you uninstalled and installed and it still didnt show up, try everest ultimate....... If you still dont see the GPU temps then it more likely you have a dead sensor.....

thanks OvrClkr
im still not sure how it happened myself...
are the heat sensors easily broken? all i did was install new drivers?
thanks again for the post

is it also possible to use my existing 3way sli bridge?

Have you tried " System Restore" ?

If not try restoring your pc to an earlier date, before the drivers were installed... If that does not fix the problem then you can undo the restore and keep on troubleshooting...

i've actualy un-installed everything related to nvidia and then installed them again, but hasn't hepled yet. what a silly thing to loose. also i get the invalid argument message in nvidia control panel. this happens only when i want to customise the fan speed - gpu temp chart.

 

[OvrClkr]

Well the only way you will know if you have a dead sensor is to do a System Restore making sure its rolled back before any changes were made... Once that is done it should fix the issue, if not then you most likely have a bad sensor and will have to use a temp probe to monitor CPU temps......

worst case scenario is i can take them back for guarantee, right? xfx does that i think. not too much harm done, but silly of me to not know where i put my sli bridge! i dont even know how long it has been disconnected for! LOL

thanks anyway mate

 

[OvrClkr]

Yes XFX will take care of you but I doubt the new cards will resolve your issue....

Just an update, I reverted back to the 186 series drivers, everything is working fine now, the temps are being read, 3way sli bridge is working, life is good

OvrClkr, I have a question I think you may have the answer to, say I have a core i7 920 running at stock 2.66, and also a 950 underclocked to 2.66, does this mean they have the same EXACT performance? or the other way round, if I overclock both to for example 3.5? from what my noob eyes can see they have the same specs on paper, so are they the same in the real world?

thanks XD

 

[OvrClkr]

Yes, you should not see a difference in speed if they are both at the exact same clocks...
