X.M.P On Orion 5000 PO5-615s stuck at 2133mhz with 3200mhz RAM

bunnydevx · July 21

Hey, so i currently have an Orion 5000 PO5-615s Core i7, RTX 3070 PC, XMP shows in the bios yet when i enable it it just sends my pc into a power loop until bios recovery kicks in, im stuck at 2133mhz with 3200mhz RAM, is there anything i can do? I have read everywhere that the Z490 motherboards can support it.

👋 Hey @bunnydevx ,

Thanks for the heads-up about your Orion 5000 PO5-615s. You're right — even though XMP shows up in the BIOS, these Acer-custom Z490 boards often struggle to apply most profiles correctly. That power loop you're hitting after enabling XMP is sadly common.

🔍 What's going on? The BIOS likely fails to train the RAM at 3200 MHz using aggressive XMP settings. It then rolls back via recovery, leaving you stuck at 2133 MHz.

✅ What you can try instead:

Here are a few DDR4 modules that tend to play nicer with OEM boards like yours:

Brand / Series	Specs	Why it helps
Crucial Ballistix	DDR4-3200 CL16	Uses Micron E-Die, stable fallback
Corsair Vengeance LPX	DDR4-3200 CL16 or CL18	Non-RGB, tighter timings, good JEDEC fallback
Kingston Fury Beast	DDR4-3200 CL16	High success with locked OEM boards

🧠 Tips:

Avoid RGB modules — they sometimes need extra firmware support.
Stick to single-rank or low-voltage kits (1.35V).
If XMP keeps failing, try setting speed and timings manually if your BIOS allows it — something like 3200 MHz, CL16, 1.35V.

📌 Sadly, unless Acer pushes a more flexible BIOS update, full XMP support remains hit-or-miss.
