so if i dont want to uses the extremest of test xtu with avx (not avx2 ?) and maybe occt linpack 2019 will be enough ?
Yeah that should be fine. That's about how my systems have been stability tested for the past while.

also how long should i test 10min? 1h? or even more ?
I'd want at least an hour. More than that is to your discretion, usually I set it to run indefinitely until I finish doing something else (sometimes an hour, sometimes 4, sometimes 8+ if its late and I want to sleep). I've never had something that runs for an hour fail to run for 4+, but it can theoretically happen.

also is linpack extreme the same as occt linpack or are they different ? linpack name confuses me there
They are technically different, OCCT Linpack did a few minor tweaks to it IIRC, but practically speaking they're the same test with a different UI. I'd only run one or the other, not both.
