Performance drops at 3200 but remains stable at 2666?
Performance drops at 3200 but remains stable at 2666?
Hi, your PC is experiencing freezing problems. After adjusting the memory settings in BIOS to 2666 and slightly loosening the timings, the Windows memory diagnostic test now passes. This suggests the original RAM might not be the issue—it could be something else affecting performance.
What processor is used? Which board is it built on? What performance standards does the kit meet?
System is noted in my notes. The issues stemmed from XMP being active. Voltage was adjusted to approximately 1.35v, and the MSI B450I TeamGroup T-Force Vulcan Z kit operates at 3200MHz with frequency range 16-18-18kHz.
Slot 2 and 4 assigned, co set to 1.1, dram at 1.35, running 3200 with XMP check enabled.
It's a Mini ITX board with just two RAM slots. The PCB uses 1:1 spacing, the RAM operates at 1.35V, and I was applying XMP profiles. The configuration it received was 2666MHz with frequencies 17-19-19-39.
Adjust CPU voltage settings to Override mode and enter 1.10. (MSI's latest BIOS is not very good, hard to locate anything.) It's currently at 1.04V.
Consider testing version 1.1 first, then proceed to 3200 using xmp.
I tested memtest86 on the machine using settings 2666 for roughly an hour while it was off. After an hour, no errors appeared. I understand issues can surface after longer periods. Still, my system occasionally freezes, especially when a stream is playing on the second monitor. Usually, the Task Manager responds but only very slowly. I’ve noticed it reports around 47% CPU usage, while all other tasks show 0%. It seems to stop updating. The only solution is pressing the reset button on the case. This behavior is really confusing. I also ran Prime95 large FFTs for over 30 minutes without any freezes. It doesn’t seem to happen when idle, but it does more often when a video starts playing without active use. I’m struggling to figure out the cause—could it be the motherboard, the memory controller, or the RAM? I don’t want to order a replacement just yet. The BIOS voltage reported by the motherboard doesn’t match what HWiNFO64 displays. When set to auto, it reads 1.04V, but HWiNFO shows 1.019V. The BIOS expects 1.12V for XMP, yet HWiNFO reports 1.087V. I’ve updated the BIOS on MSI’s site, but the problem persists. One more note from HWiNFO64: after resetting, I only changed XMP and switched CPU fans to DC mode. The BIOS still lists 1.12V for the SoC.
