Unable to get RAM recognition? ThreadRipper
Unable to get RAM recognition? ThreadRipper
You were experiencing issues with your RAM not being recognized by the ROG Zenith II Extreme. After trying a different MOBO, the same problem persisted. You decided to upgrade to the G.SKILL Trident Z Royal Series 256GB and even updated the BIOS. Despite those steps, the RAM lanes on the MOBO still didn’t register correctly. What should you do next?
You're asking about what "not register" means in this context. It refers to whether the entire 256GB storage gets properly recognized or if only parts of it do. If only certain sections aren't registered, it could be due to a cooling system pressure issue affecting the connection between CPU pins and the motherboard, possibly interrupting memory controller functionality.
The initial MOBO faced the same problem, so I replaced it with a new one. This meant the four rails on the right wouldn't recognize the RAM, leading to errors and failure to post. I had the RAM inspected and confirmed it was fine. Then I purchased another MOBO, but the issue repeated. I suspected a compatibility problem with the RAM and bought a complete set. However, the same problem persisted—the right RAM slots still didn’t register, though starting with six modules worked and posting succeeded (the extra two sticks weren’t detected, while eight caused an error). This seems unusual.
I’m working on adding more details to help you. Your setup involves a ROG Zenith II Extreme ThreadRipper with 8x32GB RAM sticks, and you’re experiencing issues with booting and recognizing memory. You tried different configurations—first with 6 sticks in A2/B2, then switched to 8 sticks—but problems persisted. The BIOS update didn’t help, and resetting the CPU didn’t resolve it. You’re now considering a new MOBO, but you’re stuck with either 128GB unused or a system that won’t boot with DOCP enabled. What steps should you take next?
There are three factors involved... The processor, the motherboard, and the RAM. What hasn't changed is the CPU, which might indicate a problem. Apart from that, the only concern is its placement in the socket; however, since you've replaced or reinstalled it and the issue persists, it's unlikely unless you consistently apply improper mounting pressure.
I'm planning to replace my RTX 2080 Ti this weekend and might reposition the CPU for a fresh setup. A ThreadRipper setup seems limited in options—maybe giving it a little shake could help it settle better?
If you followed the setup steps carefully, tightening the order and using the torque wrench correctly is a good sign. Just to be sure, some might rush through without paying attention to the details.
I verified the RAM and slots thoroughly. Everything appears normal—each stick functions properly in the working slots. However, the DIMM B1 and B2 aren’t detecting any memory at all, and slot B1 triggers an error. It’s puzzling since this issue occurs with the second MOBO as well. Is this just a coincidence or does something need attention?
