[SOLVED] SATA + Memory Madness

[cadmango]

I have a memory problem on a DELL T5500 upgrade which does not make any sense.

Context:
I just upgraded the workstation with a SSD (SATA) drive on a dual PCIE card. I cloned the old HDD OS drive successfully and everything boots up fine.
The moment I connect any one of two Toshiba 3TB HDD drives I get a memory failure on Dimm 3 error.
When I disconnect the drives the memory failure goes away and everything boots as normal.
Have reseated the dimms and moved the memory around to see if is a memory hardware failure but I still get the same failure on dimm 3.

I am at a loss why connecting the HDD drives should trigger a memory failure.
Any help appreciated as this driving me nuts.

Win 10 Pro with latest BIOS (Legacy, no EUFI option)
Drives mounted in RAID not AHCI
32gb ram (2 x 8gb dimms + 4 x 4gb: only 24gb functional if I boot into Windows with drives connected)
2 x 1TB Nvme SSD data drives connected via PCIE card.
2x Toshiba 3TB HDD data drives
240gb SSD SATA drive for OS connected via a dual PCIE card.

Sounds like you're running out of pcie lanes or something of that nature. What processor(s) do you have in it?

I saw something recently about using HDDs >2TB on a legacy systems but I don't remember the specifics. You might try it without the 3TB drives and see what that does. You might have to switch to EUFI to get the 3 TB drives to work.

Generally this is only a problem with booting, not with use the way the OP has it set up.
