New Ram, new problem (beep codes)

[stuartf]

Put in new 1 gb module (crucial) under the keyboard of my T43 (2687-D4U) to go with the 1 gb under the machine. Booted up fine x2 but then today I got an error beep sequence (alternately 1-3-4-3, 1-3-4-4 and finally 3-1-4-3) and finally a BSOD with the message:
IRQL_NOT_LESS_OR_EQUAL.

Taking the module out made things go again; is this a bad module or a bad ram slot??

Thanks,

stuart

Try the new module in the other slot. If it fails there too its a bad module.
