You don't need all 4 to boot. You only need one for the system to boot. It should bitch and whine, but it'll come up. Otherwise... do you have any other filers you can hook the shelves up to, just to pull the data off with? If no combination of memory in slots works, you may need a new motherboard.

Oh, and when you say you pulled out the pci slots, did you keep the nvram card in there? With out that, the filer won't boot at all. I'm not sure if it'll cause the 'black boxes on the LCD', but it wont' boot with out the nvram card.

you do need to have some ram to boot....

the F740 uses PC66 168pin ecc ram an example of which can be found at:

I would start with the obvious.

RAM.

I don't recall the configuration in there, been a LONG time, but remove half of it (if you can) or Ebay it..its gotta be cheap by now.

After it report some recoverable error in the ECC SRAM for about 3 days. I try to reboot but It stuck at the boot. The LCD show the top half fill with Black box. I have try to remove all the PCI card and ram for reboot with the same result. Any ideal what is the cause for this, faulty CPU / mother board or any other? Was hoping to fire it up for enough time to retrieve all the file in the system and decommission the unit. Any suggestion to retrieve the file?

Thanks, Alex Soo
