akitio + gtx 980 ti ,, frame rate is so bad . why

Hello guys , first of all thank you for everything ,, i finally got my egpu running but i dont know why the performance is below average . not even close to the real performance of this card  . 

comparing to other desktop with same gpu its a shock .

for example when i was running assassins creed syndicate on external display 1080p and the frame rate is not that good i get only 60 fps and it gets even down to 50 and 40 , 

while the normal performance of the same card can get you above 100 fps and stays between 90 to 70 .

 

my setup :

15 inch 2014 Macbook pro with gt750m 

akitio thunder 2 

gigabyte gtx 980 ti g1 

 

Can you please tell me,,,,,, is this normal for EGPU . you get like only half the performance ? or maybe something wrong here .

Hey,

I'm also using a GTX GeForce GT 980ti in combination with a MacBook Pro Mid 2014 and a Akitio Thunder2.

 

I'm getting a Score of 1934 in Unigine Heaven (complete result attached), but I've no reference. Is this all I can get with my setup?

 

Thanks in advance

@Torsten Just checked my desktop PC with a 980Ti and I scored 2240. So you reached 86% of my points and that is good for an eGPU :)

 

Thank you ,

I also got a question , a friend of mine told me that i might need to tweak my cpu voltage and some other things , he said there is that tool i can get it from Intel i dont remember its name :) 

but the problem is that i dont know the right settings or even how to do it,, i just dont wanna ruin anything :P 

 

Can you please tell us how ,, which settings do we need to change .

@Torsten Sure it would. But most games do not need that much GHz. I limited it so I will get a stable boost! E.g. in GTA V my clock speed/boost was just bouncing up and down because the CPU was throttling because of heat. I felt like I could feel that in the game.

 

Lowering the voltage will make the CPU run more efficient. All CPUs are different and Intel is just setting a safe voltage that all CPUs can run at. Most can run with much less voltage and with that, are much more efficient. -> Less heat, less noise, higher boost clocks.

 

This is very interessting due to the bad cooling a MacBook provides.

Thanks for sharing, Dschijn !

 

I got a question. What's exactly max temp, that your CPU throttling ?

 

:)
