Thanks for your help. Im using the latest bios from 2014-05. I tested your
solution and it works. "/sys/class/drm/card0/gt_boost_freq_mhz" was at 1500.
I wrote this systemd service to set it on boot. Is there a better way to do it?

[Unit]
Description=fix iGPU boost clock

[Service]
Type=oneshot
ExecStart=/bin/sh -c '/usr/bin/cat /sys/class/drm/card0/gt_max_freq_mhz >
/sys/class/drm/card0/gt_boost_freq_mhz'

[Install]
WantedBy=multi-user.target
