I have 6 sticks 72-pin 128 MB Fast Page Mode SIMMS with parity (branded IBM, all chips are Samsung).
These sticks serve mainly for testing Intel 430HX mainboards, when I check the total cacheable area and RAM population must be maxed out.
Recently there occured instabilities during the tests that I first attributed to other hardware problems, but finally I tested all 6 sticks with Memtest and found two of them to cause errors.
The contacts are clean, I couldn´t find aly loose pins and the errors are always occuring in the same memory ranges (79MB, 95MB).
How can I find the defective memory chips and is it worth replacing them? (There´s only very few space for soldering also.)
And how can I tell if a memory or parity chip is the culprit?
