razor0601 Posted February 28 Share Posted February 28 Good day all. I have a problem with my AW18 and it’s dual GTX 880m. If the HD 4600 is on there is no problem. If I turn on both 880m the screen is flickering weird. But on HDMI there is no issue. Maybe it’s the Display cable?

sliderfra Posted March 1 Share Posted March 1 hi, could be the lvds cable. If it's not, try to remove SLAVE mxm card and test it. If problem remains, try the SLAVE mxm in MASTER slot. You should then be able to pinpoint the failure on one card. Link to comment Share on other sites More sharing options...
Jerryzago Posted March 1 Share Posted March 1 Looks like the secondary GPU is on it's way out. If it were the cable, the problem would be there regardless the iGPU or the 880m. Disable SLI for starters to see if the problem is still there.

razor0601 Posted March 1 Author Share Posted March 1 Thanks, I will try. Schenker DTR 15(P751TM1) @Dsanke Bios, I7-8700, 32GB 2666MHz RAM, GTX 1060, 15,6“ 4K B156ZAN02.2 Display Link to comment Share on other sites More sharing options...
razor0601 Posted March 1 Author Share Posted March 1 So, I tried both 880m in the primary slot. Same issue, I tried also a spare Alienware 765m in the primary slot. Also same issue. Again, with only HD 4600 there is no issue on the internal or external screen. what the hell is that?

sliderfra Posted March 1 Share Posted March 1 did you try with only one mxm card and in SG mode (optimus with intel HD)? Could be the converter chip sending signal from mxm to LVDS in PEG mode. If it works in SG mode, it's most probably this and AW will still be usable in SG mode with MXM card. Link to comment Share on other sites More sharing options...
razor0601 Posted March 1 Author Share Posted March 1 Ok I will try. But first I have to flash the unlocked Bios. Schenker DTR 15(P751TM1) @Dsanke Bios, I7-8700, 32GB 2666MHz RAM, GTX 1060, 15,6“ 4K B156ZAN02.2 Display Link to comment Share on other sites More sharing options...
razor0601 Posted March 4 Author Share Posted March 4 Bad news. Also in SG Mode tested with both 880m in Slot 1 it gave me a blank black screen. With Intel HD only it starts normal.

sliderfra Posted March 4 Share Posted March 4 well that's weird... Gotta be some LVDS converter of some sort. Did you try another LVDS ribbon? Chances are low but could be that also... Link to comment Share on other sites More sharing options...
razor0601 Posted March 4 Author Share Posted March 4 Unfortunately I have no spare cable. Have to order one. What could it be also? Schenker DTR 15(P751TM1) @Dsanke Bios, I7-8700, 32GB 2666MHz RAM, GTX 1060, 15,6“ 4K B156ZAN02.2 Display Link to comment Share on other sites More sharing options...
