Bad Memory (perhaps and which?)

I have a system that since the addition of more RAM (PC-100 ECC) has began to freeze up under load.

Is there an efficient way to test where the problem could be rather than just swapping chips? I have not been able to find anything useful under various searches on google for "ram testing", "memory testing", etc.

Ideally a program that was able to load different sectors sequentially perhaps.

Much thanks,

link for memory testing tools,

Memtest86 seems be a great tool (takes a while to run tho but checks which ram is faulty and such, links you to they homepage on that site if u want to find out more about it etc,

or maybe try MemTest,

cheers

use norton system works there is a module to test your RAM...and more over u can test your whole PC for any problems either in windows or otherwise...also i am supposing u are using windows....

I agree with goozle, use memtest86

Ignore any memory tester which runs under an operating system (except possibly plain DOS). A memory tester cannot work with an OS.
