On my older firmware, the menu selection is config/expert setting
settings/more/mode. The mode setting toggles between Si5351 and MS5351.
This path may be different in 1.2.40.

The label on the back does indicate if it¡¯s using the MS5351. Someone (and
I can¡¯t remember whom) mentioned that firmware 1.2.40 included support for
both the Si5351 and MS5351. After flashing, there is a setting in a menu
(can¡¯t remember this either) to select the proper chip. If I can find that
menu setting, I¡¯ll post it.

That can change when flashing.
Yes that setting is important. IF the OP bought his H4 a few years ago
it
is the SI version. I thought the label on the back indicated if it was
an
MS version It is easy enough to try both settings and see if one works
better than the other.
The other issue is that some of the chips will not operate up to 300 MHz.
You can change the upper limit by going into Config-Expert Settings and
changing the limit under Threshold.
