IR1 Posted March 31, 2014 Share Posted March 31, 2014 So today I noticed SLI on my Y500 was not working. I am getting the yellow exclamtion on the ultrabay GPU. This sort of happened out of no where it seems. I tried downgrading drivers. I went from 335.23 to 332.21. That didnt fix it. I took out the ultrabay GPU and put it back, still nothing.I disabled and re-enabled in device manager. That took away the yellow exclamation and it says the device is working, but Nvidia CP still only reporting one GPU.I am running the modded vBios on both, but I dont actually overclock the GPU's, except to benchmark, which I havent done in about a month. So I am not sure where or what is going on. Maybe it just died, I dont know. I guess I will have to try restoring to the stock vBios and see if that does it. If anyone has any other suggestions though I would love to hear them.EDIT!!!Ok so I went back to stock vBios, and that fixed it... not sure why the modded vBios was causing problems. But I might try flashing again... maybe something got corrupted I have no idea. Very odd. Quote Link to comment Share on other sites More sharing options...
IR1 Posted April 1, 2014 Author Share Posted April 1, 2014 Ok for those that care, I reflashed the UB 650M back to the modded bios and it works now, and overclocks fine. Not sure why it got all screwy but if you have a similar issue try a reflash. Quote Link to comment Share on other sites More sharing options...
jsanossian Posted April 2, 2014 Share Posted April 2, 2014 Ahh the old reflashing trick has always saved me from bricked hardware Quote Link to comment Share on other sites More sharing options...
Per Andersson Posted May 29, 2014 Share Posted May 29, 2014 I just experienced the same thing! And solved it the same way. But now I can't overclock anymore then 135MHz. Anyone having the same experience? [solved] I realized I installed the wrong vbios. Now it works like a charm Skickat från min PadFone 2 via Tapatalk Quote Link to comment Share on other sites More sharing options...
r4jc303 Posted June 4, 2014 Share Posted June 4, 2014 Download a uninstaller application and see if it can delete everything that is related to the drivers. It sounds like something got corrupted some how. Quote Link to comment Share on other sites More sharing options...
