My memory speed isn't reaching 3200mhz
My memory speed isn't reaching 3200mhz
I own a Corsair Vengeance LPX with 16GB RAM, 3200MHz, and a C16 chipset. I can only use them at 3000mhz with specific frequencies (16-16-18-36). When I try 3200mhz, I encounter blue screens and crashes. The motherboard model isn't in its QVL (Aorus X470 Ultra Gaming), but the specs say it should support 3200. My CPU is an R5 2600.
The CPU needs to operate at that speed. I believe the issue lies with the motherboard, as many users report compatibility problems. Is there any chance I can adjust its default settings? What if it works at 1.45 with speeds of 16-18-36? I’m not very experienced, so I’d just try lowering the voltage to drop below 1.4. If that works and the system runs smoothly, consider running a memory test using Windows 10’s built-in Memory Diagnostic in Cortana. It will restart from the main window to complete the tests. If it only reaches 1.45, it might be worth the slight gain. For someone not familiar with these things, it seems like a reasonable compromise.
Have you checked both XMP configurations? If that fails, consider raising the DRAM voltage. DDR4 remains stable up to 1.5V and should work reliably at lower voltages, likely around 1.4V or less—provided your CPU can handle the MMU requirements at 3200.
I tested it using xmp on and off. With the voltage set to auto (1.35), what value should I use?
I tested it with xmp on and off. The voltage is set to auto (1.35), what should I adjust? I’d begin at 1.45 and reduce gradually. I’d manually configure the four timings as 18,18,20, 42 and 1.45 volts. If that doesn’t succeed, you’ll need to fine-tune the other 27 timings. Not every CPU can handle overclocking the MMU to 3200.
If it succeeds, I’d gradually lower the voltage to locate the lowest stable point. Then adjust the timings to 18,18,18,38.
EDIT ADD: Also worth noting, in the advanced timings menu you can search for something called ProcODT—try excluding AUTO and testing within the 40-60 Ohm range. Some may fail, but a suitable setting can greatly improve stability.

I’m not very experienced, so I don’t want to risk anything too much.

If it stabilizes at 1.4V, try a memory test. Windows 10 includes a built-in tool: Cortana Box Memory Diagnostic. Follow the instructions and let it restart from the main window environment to run the tests.
If it only reaches 1.45, you might want to consider going up to 3000 unless the slight gain matters to you.
Since you’re not an expert and don’t wish to complicate things, sticking with the current settings is probably safer, but still run the memory test. The real advantage of 3200 over 3000 is minimal and likely not noticeable.
