I think this is caused by Spectre vulnerability variant 2 mitigation which is included in this BIOS update. You can disable Spectre variant 2 protection by InSpectre program. But it will make you not protected against this vulerability in the CPU.

Same problem here with the fps drops,not with the temperature of the laptop,as i ve said in other post they should fix it fast because its unplayable in a laptop made for playing which is just ridiculous. If the problem is as somebody said before cause it includes the spectre protection well then,the laptop will run like this forever? Cause in that case i would like to speak with some employee of lenovo because i bought a gaming laptop if i would wanted a normal laptop i would ve pay 300 euros not 800,so ill sit here waiting for some response by them because if this problem will las forever cause of the inspectre program i will be really dissapointed,well at the point i will want my money back because i bought it 6 months ago and i wont accept to not playing anymore on a 800 euros laptop btw.

EDIT:

OK, it seems that the Spectre patch was also in the previous BIOS version. So it's not the case. I actually don't know what may be the case in that situtation.

How come Y520 CPU able do overclock ?

no multiplier settings i believe . and because it is intel extreme utility stress test, app like msi after burner or etc , i believe is not sync due to the test .. 

so not in overclock condition offcourse sir . its default. thats why you can imagine if doin a game at my laptop ..
