Trying to ensure XMP remains stable
Trying to ensure XMP remains stable
Hello, I'm having trouble getting my XMP stable. I've adjusted speed, timings, and voltage, but still don't see a signal—just reach the desktop after a few seconds at 3200MHz. The BIOS shows VCCSA is 0.875, which feels low. I haven't changed it yet and am considering raising it. Could increasing VCCSA to 1.3 be a safe solution?
It seems like you're exploring a voltage range for your chips. Between 1.2 and 1.4V is typical for DDR4 4000, though it depends on the CPU model. A lower voltage like 0.875V might suffice for 3200, but voltage needs grow exponentially with frequency. Raising it to around 1V would likely be the first adjustment you'd consider.
I adjusted the internal VCCS to 1.3 but no signal appears at 3,000 MHz or 1.4 volts. Timings remain 16,20,20,38,58. It reaches the desktop after a short time, yet no signal is reliable. I switched the DRAM voltage to 1.45 and reduced speed to 2800, but the issue persists.
The memory kit version is listed on the sticker, typically mentioning something like "ver. 4.32." Have you considered using single memory sticks? This would help determine if one of the DIMM slots or DIMMs isn't supporting 3200MHz and needs a return. Also, have you tried re-seating the CPU? A faulty CPU mount or bent pins can lead to memory training problems.
