Hi,

It's possible that one or more of the DIMMs is bad or possibly a slot. Try each DIMM by itself in A1 and see if it complete POST without any errors. One DIMM in A1 is required for minimum to POST. You will more than likely see a warning message, but should complete POST. If the slot A1 appears to be bad, try the DIMMs in another known good system to check if they are good. Also, check the BIOS and make sure that memory mode is set to optimized.

Thank you,

Hi Jimmy - I will go through this process to test all ram in slot A1. In my testing above, the same RAM was used in slot 1 throughout, so I  think the slot itself is okay. I will also test the ram in a different machine to confirm it's good RAM.. Probably take a few days. I'll report back as soon as I can.

Hi Jimmy,

I replied yesterday, but apparently it didn't take..

I've tested all sticks in slot A1 on the Dell I have, and it wouldn't boot with any of them. I even tried a 2gig stick of known good ram and no go.

I've tried the ram in a different server, and all of them worked with no trouble.

Are there any other troubleshooting steps I can investigate with on this Dell?

Hi,

It looks as if slot 1 is bad if the DIMMs work in another system and a known good DIMM does not work. Please DM the service tag and I will check the warranty.

Thanks,
