The following is part of my startx.log:

VGA256: et4000 (mem: 1024k numclocks: 16)
VGA256: clocks: 25.2 28.3 32.4 34.8 28.9 35.9 25.5 36.0
VGA256: clocks: 48.3 54.3 62.4 69.0 76.8 86.2 60.5 72.1
VGA256: Mode "800x600": mode clock = 36.0, clock used = 36.0
VGA256: Mode "1024x768": mode clock = 85.0, clock used = 86.2
VGA256: Mode "640x480": mode clock = 25.0, clock used = 25.2
VGA256: Virtual resolution set to 1024x1024

What is clocks? Is those frequencies belonging to the ET4000 or the
monitor? I supose that is of the ET4000 and has a unit of MHz.

The clocks in the three mode lines is always changing. Why? And can
I force them to run a specfied clock?

I'm using standard Xconfig VESA timing like below:

 "640x480" 25 640 664 760 800 480 491 493 525
               31 640 664 704 832 480 489 492 520
 "800x600" 36 800 824 896 1024 600 601 603 625
               40 800 840 968 1056 600 601 605 628
               50 800 856 976 1040 600 637 643 666
# "1024x768i" 44 1024 1040 1216 1264 768 777 785 817 Interlace
 "1024x768" 65 1024 1032 1176 1344 768 771 777 806
               75 1024 1048 1184 1328 768 771 777 806
               85 1024 1032 1152 1360 768 784 787 823

How can I change those above? What reading is needed?

Thanks,
