Processor Tests

Use Processor Tests to make sure that all microprocessors are functioning properly.
Use the CPU Functionality Test to make sure that microprocessors in the server are
operating correctly and efficiently in all address modes. To run the CPU
Functionality Test, complete the following steps:
1. From the AMIDiag main menu, select System.
2. Select Processor Tests, and press Enter.
3. Select CPU Functionality Test, and press Enter.
Use the CPU Speed Test to check the microprocessor speed. When you run this
test, the screen displays the expected processor speed and the actual
microprocessor clock speed. To run the CPU Speed Test, complete the following
steps:
1. From the AMIDiag main menu, select System.
2. Select Processor Tests, and press Enter.
3. Select CPU Speed Test, and press Enter.
4. Make sure that the test parameters are set correctly, and select CONTINUE;
Multiprocessor Test
Select this test when running the AMIDiag program in a server that has more than
one microprocessor. This test performs a variety of diagnostic tests on all
microprocessors. To perform this test, select Multiprocessor Tests from the
System menu, and press Enter. Follow the directions on the screen.

Memory diagnostic tests

Use the memory diagnostic tests to make sure that the memory board and installed
memory are properly seated and functioning correctly. You can test all memory and
the memory board on any node, or you can isolate a single memory bank on any
node to verify that it functions correctly. The following test modes are available:
v Quick test runs two test patterns through the entire free, installed memory space
v Full test runs 18 patterns, including pseudo-random patterns through the entire
To run the Quick Memory Test on all memory banks, complete the following steps:
1. From the AMIDiag main menu, select Memory.
2. Select Node n Quick Memory Test, where n is the node that you are testing,
3. Select All Banks, Quick Test, and press Enter.
To run full diagnostic tests over all memory banks, complete the following steps:
1. From the AMIDiag main menu, select Memory.
2. Select Node n Full Memory Test, where n is the node that you are testing, and
