Maverick494 Posted October 27, 2012 Share Posted October 27, 2012 Can anyone think of a reason that a retail MSI GT780DX-406US machine would get nothing but a black screen with a GTX670M? Quote Link to comment Share on other sites More sharing options...
kubarro Posted October 27, 2012 Share Posted October 27, 2012 Gtx 670m = Gtx 570m with factory 0.9 core voltage and slightly higher clocks. But basically it's the same card. Quote Link to comment Share on other sites More sharing options...
Xonar Posted October 27, 2012 Share Posted October 27, 2012 It shouldn't. The 670M GTX is plug and play in that notebook. Perhaps you missed a cable when reassembling or the card is not seated properly?Have you tried plugging in an external? What vendor is the card from out of curiosity?

What vendor is the card from out of curiosity?It was an ebay card from a vendor down in the bay area (408 area code phone number). I didn't have to do anything except take the bottom cover off and remove the fan/heatsink to get at the videocard, so no cables were touched. I can swap the 570M back in with no issues at all. I tried the HDMI output to my only available TV and it just said format not supported, so I am not sure what exactly it was outputting if anything on the HDMI.Once I get to 5 posts I might try your unlocked bios Xonar, but I suspect that is not going to change much.I guess I can use some vbios tweaking tools to setup my 570M to match the 670M settings. Its not a huge deal, it was just a really good price so I figured I would give it a try. Quote Link to comment Share on other sites More sharing options...
svl7 Posted October 27, 2012 Share Posted October 27, 2012 You could try to flash your 670m with the working 570m vbios, but I can't guarantee success. What kind of 670m is it? Quote Link to comment Share on other sites More sharing options...
myxcon Posted October 28, 2012 Share Posted October 28, 2012 I flashed my 570M to 670m bios and it all worked on, so maybe there's something wrong with the card, as you mentioned you got it for a killer price. Before buying it, did the owner provide proof of it being in working condition? Maybe the owner tried to flash an incompatible bios and damaged the card. Is it really a 670m as a matter of fact and not a moded 570m?Sent from my GT-N7000 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
