Corsair 2x16 3200 RAM fails to work with Aorus X470 gaming motherboard with 5 cores.
Hey there! I purchased the CORSAIR VENGEANCE® RGB PRO 32GB DDR4 memory kit (2 x 16GB) at 3200MHz C16, but it didn’t work at that speed. Neither single nor double channel was stable. Here’s my setup: X470 AORUS GAMING 5W Wi-Fi Samsung 860 EVO SATA III (1TB), Gigabyte RTX 2080 WINDFORCE. I previously used a Corsair 2x8GB kit and it worked fine at 3200MHz. I’m hoping someone can assist me with this issue. Thanks!
Your setup isn't quite right—processor missing. If it's a Zen+ model like the 2700X, the memory controller handles around 2933MHz. Try turning on XMP, adjust the memory frequency to 2933, and check stability. That should boost performance noticeably over 2133MHz. GL!
Verify BIOS configured the voltage to the appropriate XMP setting. Gigabyte mobos typically keep voltage at 1.2 while XMP requests 1.35 or 1.5. Alternatively, adjust DRAM voltage manually to match the XMP value.
You're asking about optimizing a gaming PC with a 3900x graphics card. It's running at 3200 MHz, which is fine for a team build using a 32GB RAM kit. You mentioned placing the cards in the second and fourth slots from the CPU, and that the VRM is underpowered—you had to adjust it to stay below 110°C during stress testing.
I'm sorry, I missed that part. It's a 2700x processor, and I attempted to lower the clock speed to 2933MHz about 20 minutes ago. After testing with MemTest, everything seems to be functioning properly. Thanks for your help!
I encountered a comparable problem with a Gigabyte b450 ud3 using a 2700x board. I posted with XMP activated and used a 2 x 16GB Gskill RipJaws V DDR3200CL16, but it didn’t run smoothly. Adjusting the DDR voltage to 1.35V seemed to resolve the issue. The same forum thread recommended adding a +0.078V offset for Vsoc and turning off DRAM power-down in Peripherals. A small increase in Vsoc voltage could provide extra performance to the memory controller. It remains Prime95 small FFT stable, though this is likely due to the board’s weak VRM. After roughly 10 minutes it exceeds 120°C and the system freezes. Occasionally, raising the DRAM voltage slightly to 1.4–1.43V helps, but results vary based on CPU memory controller quality.
