Confirmed. It was the wrong RAM. After switching to UDIMM it posts and I was able to update the firmware.
I obtained a Dell T330 recently that is running BIOS 1.0.2 (which I believe is the factory default, so clearly never updated). As a result, I'm encountering the well known issue, "Memory is detected, but is not configurable". As I cannot get the machine to post, my thought was to update the BIOS through idrac. I was able to successfully update the idrac firmware to 2.43.43.43 without an issue.  I downloaded the oldest version of the BIOS available from DELL (BIOS_832M2_WN64_2.3.2_02.EXE) REF: [URL]  It uploads fine and I select "Install and Reboot", which as expected kicks it to the job queue.   [IMAGE]   The job queue, shows it downloading, then it reboots, and shows the following: [IMAGE]   This is where I'm stuck, it never transitions out of "Scheduled". I've tried a warm boot, cold boot, graceful shutdown, nothing seems to help. On the VGA display output (as I don't have idrac enterprise), it just shows the existing error for "Memory is detected, but is not configurable." I've been at this on/off for two days, so any help is appreciated.
