Ran the memory pattern stress test that Dell supplies with this computer. All memory passed.
Just a note since we haven’t resolved this yet.
Memory Stress Tests don’t run once and we’re done. They loop and run all night while you’re sleeping. A memory stress test on a healthy machine should run perfectly correctly for 8 or more hours.

PASS 31 WAVE OVERLAY SHIFT TEST – 100% COMPLETED
PASS 31 ALTERNATE RECURSION INJECTION TEST --100% COMPLETED
PASS 31 COMPLETED – NO ERRORS
PASS 32 RUNNING DOG CHECKBOARD LOOPBACK TEST – 57% COMPLETED.
I had an marginally stable machine that passed all sorts of tests until I left Mem-Check running all night. Somewhere round 3:30am (Pacific) one of the memory torture tests failed and the machine went face-first into the gutter.
PASS 83 SPARKLE REVERSE ADDRESS TEST FAILED!! - BANK 4 ROW 1.
PASS 83 TEST HALTED
I fixed the bank and it’s been running for years since then.
