Hmm...It's not game fault. I'm 100% sure. Each game I trying to play with SLI enabled is ending with crash. Tested dying light , bf3 , bf4 , Bf hardline , middle earth , zombie Army trylogy , even gothic 3 ... Im dump. I feel rly bad. I payed for gaming laptop so much money and it working lukę 3/4 of price version with one card. I have Clue for you : never buy laptop with SLI especially from Lenovo... Peace out. I Retrie. c EDIT: I fixed it partially by Forceware_coolbits from http://www.Guru3D.com but still there are situations for example in CS:GO where i getting random artifacts and display freeze/sound loop occur. Now i can play GTA 5 with sli with no crashes but it isnt complete fix. I'm looking for help from you .

I did update of bios to 3.08 butt it wont fixed anything + i have updated bios from support site of lenovo for ultrabay card

I did stress test with prime and 3dmark in same time and my laptop sucessfully survived it maybe not like a charm but it passed without crash. Any clues ?? I'm dump I send to you my temps when hung/ game freeze/ driver crash : http://prntscr.com/6o1fq8 . I send to you my dxdiag : http://www.speedyshare.com/BHQb5/DxDiag.txt . I hope someone will figure it out because I Gave up No more ideas what to do. In the end i will try overvoltage ...

I can say that voltage is on stock. I was trying previously underclocking but it didnt worked so i went back to default settings. I tried factory drivers and still it wont working. I can't find stock bios for ultrabay card (I have upgraded bios from lenovo support site but it isnt fix). I will try to run prime95 and 3dmark in same time but i guess that wont change anything.

As I said in furmark everything is ok. I was trying to undervolt and underclock but this didnt fixed my problem. My hardware is 100% no damge because I sent month ago my laptop to service to check that is a hardware and it isnt it. I can make stress test with any program and still everything is ok. So I'm dump. I dunno what is wrong with this laptop Also i scaned my system with malwarebytes and it didnt fixed anything. I was trying almost all kind of fixes (tdr in register change, undervolt , underclock, nvidia control panel various of settings, nvidia inspector, msi afterburner and more...) so I dont know what to do There it is : View image: sli755m As you can see temps of ultrabay card are not even close to 90 degress. I'm dump what is wrong.

Hi all. I have huge problem here. My laptop is slowly making me mad. So my sli causing crashes "display driver stopped ressponding and recovered" and "device has been removed or hung/hang" and ocasionally BSOD " dpc_watchdog_violation". I send back my laptop but lenovo said that everything is okey. In benchmarks sli works like charm even in furmark but while gaming it random crash with screen freeze but game is still running (sound works well so i know that only display is frozen) so i have to use alt+tab to escape this crap. Is there anyone who can give me solution or advice how to fix this issue ?? What have i did so far : - vbios updated of second card -all drivers up to date -reinstall and downgrade to previous versions -it isnt becouse of temps. (its about 78-89 degress of celsius) -clean reinstall of OS WIn 8.1 -system is up to date -no hardware isuess found -crashing even on games like Counter-strike: GO (i have about 120-220 fps on maxed settings on sli and 58-120 fps on single card) -single card doesnt couse crashes Sory for my bad language . I'm looking to hear from you

allstone - I love you bro. Ideafan is rly amazing tweak for high like toaster temps :3 Is there possibility that there will be some way to make constant for example 90% fan usage ??

Is there any chances that flashing modded bios will fix my sli (crashing-display stopped to ressponding and have recovered/ Device has been removed or hang) problem ??

Hi guys.I'm from Poland and I have rly bad lenovo y510p 755m sli version. It's pain. All games working only on 1 card meanwhile benchmarks and even furmark can last for 1 h without crash on 2 :3
