Evaluating my system for Octane_problem Tweet

[Ariandesign]

Hi,
I've a workstation based on a dual xeon setup (2 x xeonE5 2695V2 with 64gb of ram)....I'm trying to test on it a Gtx 1080 ti (Asus turbo, with stock frequency, NO Overclocking, blower cooler).

I'm obtaining an average score of 175..........is it ok?

My cpu are 2.8ghz cpu (12 cores each)

The weird thing is that the score obtained with Octanebench is not always the same.....the scores varies from 170 to 180.....is it normal?

Because I've tried the octanebench into another workstation of mine, and the score is always the same......only in this system, the score changes....

I hope to have posted into the right section....thanks for any help /suggestion....
