Question Instability/Freeze (Only Freeze) R7 2700x + Crosshair VI

Sep 13, 2018
Hey guys,

Been having some issues ever since I've started playing around with my BIOS settings in order to try get stable while trying to reach higher SC speeds by letting PBO and XFR do its thing. Occassionally, with no pattern, my PC just completely freezes (No Crash, no BSOD, no crash logs, nothing anywhere) and I have to pretty much forcefully shut it down to get it back on.

I originally thought it would be my memory and I am pretty certain it is my memory, but I don't understand why.
I'm running Hynix modules from Corsair. Was planning on going for G.skill 3200 Mhz CL14 (B-die) but I wanted to see if I could atleast get some stability with these, though I'm still not certain if my issue is my memory.

My Current Setup:
  • Ryzen 7 2700X
  • Asus Crosshair VI Hero
  • CMK16GX4M2B3200C16 (Corsair 2x8 3200 mhz CL16)
  • Latest BIOS 6401
  • Windows 10 Pro Version 10.0.17134 Build 17134
  • Corsair H150i 360mm cooler
  • Gigabyte 1080 Windforce OC
  • Corsair HX850 Platinum
I'm currently running a ASYNC BCLK overclock. I'll just go ahead and post all of my BIOS settings. (I know I could have taken screenshots from the BIOS but I knew my settings by heart and didn't have USB so I hope this is fine).

  • Running a manual tuner (Ai Overclock Tuner set to MANUAL)
  • Async BCLK set to 102.4 (Still a fairly low amount to have any worries for stability, but my PC seems to be FREEZING at anything above 101.8). Please mind that this is Async BCLK, so my PCI-E slots and USB hubs and memory controllers are not affected.
  • Core Performance Boost set to Level 3
  • Memory Frequency is automatically set to 3200 Mhz.
  • Running 16-18-18-18-36 Timings
  • DRAM Voltage set to 1.38 as 1.35 felt pretty unstable (Thats what I thought the reason was for the freezes so I bumped the voltage slightly)
  • CPU Core Voltage Offset at -0.0275 (Could run at a much higher Offset, but my BCLK doesn't seem to support it since my SC almost pushes 4.5 Ghz)
  • I left CPU SOC at Auto (Haven't tried 1.1-1.15 values)
  • Bumped my 1.8V PLL Voltage to around 1.81 for the BCLK push
  • Running LLC level 2 (Felt like this was a sweet spot)
  • CPU Power Limit set to Max (140%)
  • CPU Power Phase Control = Manual
  • CPU Power Duty Control = Extreme
If there's anything I've missed which could be relevant please do let me know and I'll update my post. Any advice/feedback would be greatly appreciated. I honestly just want to maintain BCLK levels moderate in order to push 4.5 Ghz SC.

My voltages during Cinebench + P95/IBT under full load are around 1.32 - 1.36, varies honestly.
Voltages during gaming (Due to PBO/XFR) can peak 1.5 for just a few seconds until it can drop back down to 1.375-1.417. This seems to be a pretty big gap but it varies between those numbers. Though it seems to stay more above 1.4 in gaming at a constant rate.
