New server build; can't get it to boot (9960X/ASRock WRX90 WS EVO)
UPDATE: Resolved - thanks u/nauxiv!
I'm trying to get this new server build to boot and I'm not having any luck. I've tried all the usual things (see below) and now I'm wondering if I have a hardware incompatibility that I missing.
Specs:
- Motherboard: ASRock WRX90 WS EVO
- CPU: AMD Ryzen Threadripper 9960X
- RAM: G.Skill Zeta R5 DDR5 RDIMM ECC
- F5-6400R3239G16GE8-ZR5K
- 8-DIMM kit
- GPU: EVGA RTX 3090
- PSU: SilverStone HELA 2500Rz
- BMC firmware: 1.04.00
- BIOS: updated to latest available
Symptoms:
- System does not POST
- No video from RTX 3090
- No video from onboard/BMC KVM
- Dr. Debug cycles through codes, including 15 and d6, then resets to 00
- Appears to be boot looping
- With no RAM installed, Dr. Debug sits at 00
Things I've tried:
- Started with full RAM kit, then reduced to 1 DIMM in A0
- Tried more than one DIMM
- Removed RTX 3090
- Removed storage / minimal config
- Confirmed both EPS CPU power cables are connected
- Cleared CMOS with button and jumper
- Updated BIOS
- Reseated CPU
- Checked BMC sensors
BMC observations:
- CPU temp and voltage rails are present
- PROCHOT_CPU shows asserted
- BMC memory inventory shows stale/weird DIMM data that does not match current physical config
Help?
