Two 512 mb ddr266 ram causing freezes?

Mobo: d845gvsr with p4 2.4 ghz and bios version p10.

When i put both ram in the 2 slots windows loads, works fine and then freezes, randomly. Sometimes after hours, sometimes after seconds. While it freezes, the screen gets distorted, i mean display. And i have to force system restart by long press power button. Any other combination of any 1 of those ram with the two slots work flawlessly. What do i need to do now? I need to run a memtest bt assuming i got full passes, what more can i do to troubleshoot and fix the issue?

    see the support pages for ram.

    your ram may be the wrong organisation

    eg 128x16 same size as 64x32 but different organisation.

    effectively this equates to the no of chips on side of each dimm

    This also equates to a type of SHAPE if you like.

    consider a chess board 8x8 representing the MAX memory.

    think of a ram dimm as say 2x8

    now think of the WRONG dimm as 4x4, it overlaps the other socket or effectively only half fills it.

    you could have the wrong arrangement(shape) ram

    preferably use ram mentioned in the tested list.

    both dimms must be SAME CAS LATENCY ie CL no.
