Perfomance drops / not a heat problem

[gg1103]

Hi all,

I find that the speed of my GTX 1080 graphics card in connection with WPA2 drops from about 420 kH/s to approx. 31,000 H/s during approx. 2 minutes.

I have checked that I have the latest driver and that there is no dust that prevents cooling.

Constant temp. readings: Dev.#1.....: Temp: 57c Fan: 33% Util: 92% Core:1936MHz Mem:4608MHz Bus:16
Watchdog: Temperature abort trigger set to 80c
Watchdog: Temperature retain trigger set to 75c
I have previously not experienced a decline in speed.

Do you have any suggestions for what I can do?

Thanks in advance.

That depends on 2 factors:

1. value of nonce-error-corrections
2. number of networks using the same ESSID

and is a normal behavior!

examples:
using nonce-error-corrections 0 on a hccapx file containing different ESSIDs
Speed.Dev.#1.....:   517.5 kH/s (6.61ms)

using nonce-error-corrections 8 on the same hccapx file containing different ESSIDs
Speed.Dev.#1.....:   450.3 kH/s (6.60ms)

using nonce-error-corrections 0 on a hccapx file containig the same ESSID
Speed.Dev.#1.....:    58843 H/s (3.77ms)

using nonce-error-corrections 8 on the same hccapx file containig the same ESSID
Speed.Dev.#1.....:     4577 H/s (3.74ms)

Also check that there is only one handshake in the capture.
