Upgraded RAM, long beep, no boot

[track_cheetah]

I was running freeNAS on a HP z220 SFF with 8GiB of RAM.

I pulled an extra 8 GiB from another z220 to increase the freeNAS RAM to 16Gib

On reboot the computer gave one long beep and would not boot.

Removed the extra 8 GiB

Reboot and everything was fine.

Tried removing the BIOS battery and reinstalling 16GiB

Reboot and beep.
----------------------
Rearranged the RAM and now no RAM/DIMM configuration will boot the machine

No to 4Gib, No to orginial 8Gib configuration, No to 16Gib
----------------------
When installing I was not strapped in and grounded to the machine but I kept in-contact with the machine during the entire swap process to prevent static discharge

What does it do with no ram installed? Also what do the LEDs do? You indicate one long beep but the manual for this machine doesnt say anything about one long beep.

with no ram installed i get four beeps on a cycle. the power LED remains a solid blue when the long beep is heard. I can enter the boot config before the machine sounds this dreaded beep but as soon as i exit i get the beeeeeeep. I searched the manual you cited (thank you for the reference) and I also found no possible troubleshoot solution. Is the freeNAS usb that i'm booting from corrupt maybe?? I dont think i have any other boot media available at the moment but I can always download something. When i pulled the freeNAS USB and plugged it into my laptop it only registered on the Disk Management program for Windows 7. Even then i wasn't able to do much with it.

update:
The machine has Intel boot agent. PXE is the first boot and will not allow me to change this in the bios. It must have been defaulted to when I removed the battery. I have sourced an update from Intel to turn off the network boot but I have to be able to boot to a USB before hand. The next step is to created a network boot of freeNAS maybe? If anyone has experience please share.

I feel like once back in the day I had a similar issue and it was related to CPU fan and in fact it was a SFF HP machine. It was a hidden setting in the bios and could only be activated by holding a certain key while entering the bios. Then I disabled the checking of the CPU fan, in fact it was a fanless machine, and voila all good.

I'm sure you have loaded optimized defaults but you might research this setting and see if it applies. Some Google Fu should get er done.

If you are getting to bios then the ram is "working".
