Greetings
🙂I have recently purchased a second GTX1080 Strix for an SLI setup. I was careful to buy the exact same version of the card already installed in my system, the M1 variant (with gaming mode clocks at 1734 MHz). Former drivers were DDUed
🙂 and installed the latest (381.65). From what I´ve being observing the GPU clocks run exactly at the same speed but voltages are always diferent under load. GPU1 is always .05 mV higher than GPU 2. Is this an issue?!
The experience I´m getting from gaming had a bit of a rough start (but at that time I didn´t know about Nvidia Profile Inspector)
Homefront The Revolution: - FPS increased a bit but not to the extent I was expecting (will try again with Ryse bits :))
Just Cause 3 simply doesn´t have an SLI profile.
Deus Ex Mankind Divided: although plagued with crash and performance issues, after some tweaking (graphic settings very high and Overwatch bits) I was able to play (Criminal Past) decently hovering 55-70 FPS on Full Screen and 60-100 on Exclusive Fulscreen (until is gave me a CTD after 15-20 minutes play). Anyway, those FPS, specially on Exclusive Fullscreen, are quite in the interval I expect from SLI.
HITMAN: another strange SLI performance - could be getting 100 FPS in one spot and 25 on another.
This is after playing HITMAN
Although not depicted in that image I could almost say for sure that despite GPU 2 being fed with less .05 mV it has more usage than GPU 1. I´ll check that when I get home.
On more taxing games like Deus Ex I get 1050 mV in GPU1 and 1000 mV in GPU2. The difference has been always .05 mV
Thnx for your attention
