Support 📥 First build boots to 0d error when cold. Immediately restarts fine into Windows. Also, Boot Failure on cold boot after increasing RAM MT/s.
I just built my first PC with the help of a friend who is more knowledgeable than I, and I'm *almost* to what I'd call a success but the two issues in the title have stumped both of us.
Here's the hardware (copy pasted from my order since I don't really know how much of these titles are relevant), all of it is brand new within the last 2 weeks:
- AMD Ryzen 7 9800X3D - Ryzen 7 9000 Series Zen 5 8-Core 5.2 GHz - Socket AM5 120W - AMD Radeon Graphics Desktop Processor - 100-100001084WOF
- GIGABYTE X870E AORUS ELITE WIFI7 AM5 LGA 1718, ATX, DDR5, 4x M.2, PCIe 5.0, USB4, Wi-Fi 7, 2.5GbE LAN, EZ-Latch
- CORSAIR Vengeance RGB 32GB (2 x 16GB) 288-Pin PC RAM DDR5 6000 (PC5 48000) Desktop Memory Model CMH32GX5M2E6000C36
- GIGABYTE Gaming GeForce RTX 5080 16GB GDDR7 PCI Express 5.0 Graphics Card GV-N5080GAMING OC-16GD
- CORSAIR RMx Series RM1000x ATX Power Supply - Fully Modular - ATX 3.1 - PCIe 5.1 - Cybenetics Gold - Low-Noise - Japanese Capacitors - 1000 Watts
- SAMSUNG SSD 9100 PRO 1TB, PCIe 5.0x4 M.2 2280, Seq. Read Speeds Up to 14,800MB/s, Best for AI Computing, Gaming, and Heavy Duty Workstations (MZ- VAP1T0B/AM)
The case is the Phanteks EX5 Max which has a built in AIO cooler for the CPU.
Here's my first issue: When I boot up cold, it immediately (or within 1 second) gives me a motherboard error code of 0d. It will stay there forever if un-messed with. If I reboot by holding down the power button or by just hitting the restart button, it then boots to windows with no issues.
Second issue: When enabling XMP in the BIOS to unlock 6000 MT/s from the RAM (instead of the default 4800) the computer will boot into windows normally from the BIOS. A check ensures that the RAM is at 6000 MT/s. But then, any boot or reboot warm or cold leads to a boot failure, with the only option being to go back to 4800 MT/s.
And here's what we've tried so far:
All drivers updated
Updated the BIOS to version FB2f
Reseated the RAM (They started in slots 2 and 4, and they were reseated in 2 and 4, just in case they weren't fully clicked in)
Tried stepping down the boosted RAM speed from 6000 to 5800, 5600, etc, with the only successful one being the default 4800.
My friend says if we can't fix it, booting twice every time is not the end of the world, nor is having RAM at less than maximum speed. And while he's right, I sure would like this whole thing to just WORK. Any help you can give is greatly appreciated!
