I think I bought the wrong memory for my RAM for X8ST3-F

[Alfa147x]

(I screwed up the title and can't figure out how to fix it )

I have a Supermicro X8ST3-F and Intel Xeon X5650 running 2x CORSAIR Vengeance LP 16GB (2 x 8GB) 1600 (PC3 12800) for a total of 32GB of memory. I tried to replace it with 6x 8GB Samsung PC3L-10600R (total of 48GB) off of ebay.

I ended up receiving:

• 2x PC3L-10600R-09-11-E2-P2
• 3x PC3L-10600R-09-10-E1-P1
• 1x PC3L-10600R-09-10-E1-D2

Troubleshooting attempts each with CMOS reset in between:

• Tried each stick of memory in slot A1
• Matching sticks in both A slots

I haven't been able to get anything on screen and no beeps but the fans spin up.

Currently my options are:

• Return memory and buy the correct type
• Sell motherboard and get a new one

Any ideas what to do next? Thanks!

I use only Hynix memory in my SM boards. Never had a problem.

You bought ECC Registered memory (10600R), but board X8ST3 has X58 chipset, which does not support that. So you either need to get non-reg modules or motherboard with 5500 or 5520 chipset.

Easiest seems to buy two more Corsair modules to get you to 48GB and sell those RDIMMs.

Thanks for the help. I knew I missed something! I'll go ahead and return the memory and start over. I picked up the ECC sticks for my venture into FreeNAS.

I should have a few DDR3 sticks that will work in that motherboard if you're still looking for some. However, as per Supermicro your motherboard only support only up to 24GB of memory.

So here is my conundrum: I've been able to run 32GB of Corsair memory (non-ecc) with no issues. According to this thread, it's due to that the memory controller is on the CPU. I would like more than 24GB (32+ is my goal) since I don't want to upgrade for a while.

Options:

• Sell motherboard and buy more compatible motherboard
• Try to run 48GB on my current board

Thoughts?

Seeing you have running already 32GB, going to 48GB shouldn't be a problem, but its officially unsupported. You would just need non-reg ECC or desktop modules. More compatible motherboard means dual socket, as I am not aware of any single socket 1366 board supporting RDIMMs.

Dual socket with 6 memory slots per CPU means EATX dimensions (e.g. X8DTi). ATX board like X8DTL have only 3 slots per socket thus you would either need second CPU or 16GB modules.
