New CPU and Supermicro board connect to the web interface, but BIOS setup isn't available.
I purchased a CPU motherboard combo from eBay, expecting a Supermicro mobo H11SSL-i with an AMD Epyc 7551. After connecting it to the network, I received an IP address via DHCP and was able to access it through the web interface. Upon inspection, the CPU provided was actually an AMD Epyc 7302. Checking the BIOS menu revealed a POST Snooping code of 16. According to the Supermicro manual linked, this corresponds to a "0x16 Pre-Memory North Bridge initialization (North Bridge module specific)" error. So, your suspicion about a memory issue seems correct. Additionally, you didn’t connect the four-pin connector on the top left. Your specs match: Processor – AMD EPYC 7302, 16-core, MOBO – Supermicro H11SSL-i, RAM – Kingston FURY Beast 64GB 3200MHz DDR4 CL16 (x2), PSU – beQuiet 700W.
You can still use your PSU even without a dedicated 4-pin connector. Look for adapters or alternative connectors that fit your power supply model.
Welcome to the realm of high-frequency ECC DDR4... I've been searching for additional modules for my H12SSL-i, and I think I'm about to invest in an area where memory availability is uncertain. So far, two orders have failed because they couldn't deliver at the agreed price. (Also a big thumbs up from Epyc!) If the 4-pin connection doesn't fix the problem, I'd consider getting some QVL (or nearly equivalent) memory for this setup. It'll be challenging, but it's better to proceed. Do you have an additional CPU with an 8-pin, or should I just leave it hanging off the plug?
It's accurate, yet I also have a faster CPU and a more recent model. Likely I won't need a 32-tread configuration anytime soon.
