Let me provide some assistance on this situation.
The system BIOS does not require any change after a memory upgrade. First, we need to see what triggered the fault light on the system. For this, you may download and install the Intel® Active System Console you may also run the Intel System Information Retrieval Utility to capture the logs of the board.
You can also check the system BIOS to see if there is any report of errors with a particular stick. Press F2 during POST > Advanced > Memory Configuration.
What is the part/ model number of the new memory?
Thanks for your prompt info. In reply the Crucial ram type etc taken straight from their invoice ...
4 off 4GB DDR3 PC3-12800 CL = 11 Unbuffered Non ECC 1.5V 512Meg X 64 ... DDR3 1600
Part No - CT 3724549
As i stated i did use the downloadable Crucial RAM requirement analyser and ordered there and
then from them.
Thank you for the information. I checked the specifications of the memory and noticed that it is Unbuffered Non-ECC memory. This system board only supports ECC memory. This might explain the erratic behavior we have seen.
You may refer to our validation list for more part numbers to use on this board.
Cheers, David. I will order the correct RAM this morning and confirm the outcome to you in a couple of days. I would have assumed that the Crucial analyser software software would get the required spec correctly .... another lesson for us.
New and correct and different manufacturer ram fitted Friday past and issue solved. Thanks for your speedy advice.
Disappointed that Crucials downloaded software for compatible ram needs analyser was blatently "wrong".
