Z370 + 8700k - 3Dmark 01 running slow

[havli]

I have new rig for benchmarking old GPUs. i7 8700K @ 5.4 GHz, ASRock Z370 Extreme4 and 2x8 GB DDR4 4100.

Now the problem is, I can't get proper 3DM01 scores with this system. Few years ago I had 7700K with Maximus VIII Ranger and the system was somewhat faster despite lower CPU clock and much slower memory. As far as I can tell, the drivers and settings are the same now like I had back in 2017. The winXP install is different, but that canť make the difference or can it? All the CPU limited tests (especially CH, DH, LH) are slower on Z370.

So for instance these scores.

All other legacy benchmarks perform better on the 8700k (as expected), but not 01. Is there something I am missing, or simply some boards are for some reason slower and nothing can be done?

Thanks for any tips.
