IBM ValuePoint - Video corruption
Applicable to: World-Wide
Symptom:
A limited number of ValuePoint Performance Series systems (64xx) contain video memory that, under some circumstances, may cause video problems such as :-
1. Dots or unreadable characters randomly appear on the screen - particularly when a window is dragged.
2. A checker board pattern is displayed.
3. Horizontal black lines pass through the displayed image.
Problem Isolation Aids:
Only system boards with video memory modules from Micron Technology are affected. The video memory modules are located between the video memory expansion sockets (VMEM 1 and VMEM 2) and the riser card connector. Modules from Micron Technology have "MT" before the part number printed on the module. If the video memory modules are not marked "MT," this tip does not apply.
Fix:
If the system board contains video memory modules from Micron Technology, replace the system board. Order p/n82G2397 for 25mhz, 33mhz, and 66mhz system boards and p/n06h6355 for DX/4 100mhz systems. If the video memory modules are from any other manufacturer, continue with normal problem determination.
