PLEASE HELP (ZOTAC 780 TI AMP SLI BIG ISSUE ) I Don't know what to do

[Joacko_1990]

Hi guys im kind of new in the comunity . Today i finish building my rig with 2 780 ti sli and i have a huge problem . I will show my settings :

I5 3570k at 4.4 ghz : Voltage 1.36 ( Temperatures max 70)
kingston Predator 2x4 : 1333 stock
motherboard z77x-up7
2 geforce 780 ti Zotac amp / with out any oc
Psu Sentey 1000w ltp1000-sm Platinium 83 amp
LG LM7600 resolution 1920x1080 60hz . Hdmi plug
Last nvidia drivers : 340.52

Im playing crysis 3 with only 40% of both gpu making big Frames drops every 10 seconds .
I dont know if the issue is with the Gpu or Cpu . This is Stuttering ? . i will show you some pictures .
In another hands with the heaven benchmark : Gpu both are at 90% 80% but after few minutes ; in some parts the gpu go at 40% 30% making some kind of quick Freeze

Anyone can tell what is my problem ? im really sad and worry for Spending some much money working hard and play like this .

Sorry for my english . Thanks you






Edit : in witcher 3 after few minutes .. my screen keep freeze making wierd noises with the sound of the speakers and one of the gpu go to 0%

They might not support sli, disable one card, you'll be better off. Not all game support it you see so stuttering and stuff you mentioned are sli related problems

Looks as though that 3570k is pretty much bottlenecked in that part of the game in Crysis 3 "welcome to the jungle" I've tested my 4770k and 4790k extensively in that map probably 6 hours+ total. My average cpu usage after about 20 minutes is around 60% and that's 8 an thread cpu. Look at your cpu cores usage it's close to 100% usage on all cores. My 4790k at times hits 80-90% overall cpu usage in that map, your i5 is hitting 100% more often, since it has 4 cores, no hyperthreading. If you want to eliminate as much cpu bottleneck, get at least an i7, better yet a 6 core cpu. i5 with 2 high end cards is an imbalanced system.

But this is tom's an i5 is a godly processor good enough for everything, even 4 x Titan's and the 'bestest' there is.

@ Legend

lol, Crysis 3 is one of the better games that scales in SLI. I would even say close to 100%.

hmmm, it just doesn't seem that the gpu is sharing power that well, i'd still advise the Op to disable it and see what happens

 

[marc79]

Simple that cpu can't keep up with those 2 780 Ti's in that part of the game.

 

[Joacko_1990]

but what about the Freeze in benchmarks with 90% and 80% of the Gpu . You are saying that my i5 3570k at 4.4 ghz cant keep up with all the games ? i play witcher 2 with one gpu . and i can play it Perfect. but when i do Sli.. my frames drops more and i get 30% 40% Gpu usage .

 

[legend001523]

yes, sli issue, just play with one gpu

 

[Joacko_1990]

i downgrade the graphics to see what happend with the cpu and is not even at 77% in all cores but the Gpu % is the same .



i cant play with one ! i buy it for 700usd . i bleed for this card . maybe is the motherboard ? RMA for the cards?

 

[legend001523]

Why can't you just disable one gpu for this game and see?

 

[marc79]

You are testing a demanding level of Crysis 3, with 2 x High End GPU's, with a 200 dollar cpu, what do you expect.

 

[Joacko_1990]

This is my performance with 1 780 ti . 55-65 fps : The cpu is perfect. So why would be crashing with 2? people everywhere saids that i5 3570k can handle it perfect. thas why i think maybe is the gpu

It's cause it doesn't scale well, well, this game might not, just play with one gpu and for games that support sli well, enable sli

 

[marc79]

Yeah people on tom's said it would be perfect, i5 over here is considered top cpu. I would never recommend an i5 for 2 high end cards, never, it doesn't make sense. It's great for a single high end card, but not when you're pushing 2 high end cards.

Lifestyle comment: If you had to "bleed for this card" maybe 60FPS on ultra settings on one of the most graphically demanding games on the planet is enough and you should sell the second card. Especially since you are gaming at 1080p with a single monitor, having that much graphics horsepower is somewhat pointless.

Otherwise, marc is probably right that at such an extreme of graphics power, and i7 may perform better.
