AORUS 8GB RAM, 4400MHz issues; computer fails to start.
Hello, just finished a build with all new components installed. Everything appears to function properly. In the BIOS, I configured my RAM to XMP specifications at 1.5V and 4400MHz, but my PC keeps rebooting and sets the frequency to 2666MHz. On Gigabytes, the recommended specs match when using this motherboard. The motherboard claims support up to 5000MHz, and the system is advertised for that. Currently I have four 8GB XMP modules running at 1.5V and 3900MHz, but not at the desired 4400MHz. Any insights? Thanks! PC specs listed below. CPU: 10900K, Motherboard: Gigabyte Z490 Aorus Master Waterforce LGA1200 ATX, Memory: Gigabyte 16GB Kit (2x8GB) DDR4 Aorus RGB 4400MHz, OS drive: MA Corsair Force MP600 2TB Gen4 PCIe N0Me M.2 SSD GPU: Gigabyte GeForce RTX 3090 Xtreme Waterforce 24GB GDDR6X e0GA SuperNO0A P2 1200W 80PLUS Platinum Power Supply.
The computer restarts itself because the motherboard can't support the memory at that rate. You mentioned it's claimed to handle speeds up to 5000MHz, but this is likely specific to a certain model and setup. Don't focus too much on the promotional content. The key issue is confirming whether the memory kit you purchased (part number) exists in the QVL. Even then, performance hinges on the quality of the memory controller on your CPU. The chip selection is crucial here. Please find below the only verified 4400MHz memory options for this board. The complete list is available there. From the list, you won't find a 4x8GB 4400MHz configuration that's confirmed as compatible. The top-rated 4x8GB setup is for 4133MHz and is designed for ADATA memory. At the end of the QVL there is also a note:
Approximately 4400mhz works with two slots, though it fails with four.
The best frequency and voltage depend on the specific device or circuit you're using. Since you're just starting out, it's best to check the manufacturer's guidelines or a reliable reference for your setup. If you share more details, I can help narrow it down! Thanks!
Intel lacks an Infinity Fabric, so performance improves with higher memory frequency. However, settings and voltage aren't one-size-fits-all. Since your system is already at 1.5V, I wouldn't exceed it—this is the safe maximum for DDR4 under continuous use. I suggest maintaining current timings and gradually reducing the frequency instead. After booting, run Linpack Xtreme or Intel Burn Test to verify stability.
