I upgraded an older ECS motherboard (K7VTA2) from 1 x 128 MB SD-RAM to 2 x 512 MB DDR-RAMs.

Yes, my Motherboard has two different RAM-Slots/Banks:
two for older SD-RAMs and
two for newer DDR-RAMs

However, since then my Monitor occasionally starts to flicker when I drag windows over the desktop.
Parts of windows remain on the screen when dragging. The whole desktop is not completely rebuilt

Why ?

Everything else seems to work fine.
The full 1 GB memory is recognized (as visible in the TaskManager).

Maybe I have to change some RAM settings in my BIOS because of the RAM type switch.

The current settings are:

Current FSB Frequency=133 Mhz
Current DRAM Frequency= 100 Mhz
DRAM Clock=100Mhz
DRAM timing=Manual
SDRAM Cycle length=2.5
Bank interleave=4 Bank
DRAM Queue depth=4 level
DRAM Command Rate=2T Command

Do I have to change these settings?

I am using WinXP+SP2
My video card is a GeForce FX5200

At first glance, I'd guess your new memory should run 133/266 speeds
if it is DDr, so you could increase the memory frequency and dram
frequency to 133. It sounds like you might have a vid card driver
issue. Try reinstalling the vid card drivers, and any AGP drivers for
your chipset. I'd also set the dram timing to "auto" if such a
setting is present in your CMOS setup.
