Hi, running a 3950x on an admittedly inexpensive MB (Asus Prime B450M-A), with 48GB Ram, 2060S, and 650W Corsair CX650M PSU.
1. At stock I get a all core boost of 3.9GHZ under CB20 (long term) - Is this a bit bad for a DR4Pro - Would you suggest a reinstall?
2. Using a darkrock 4 pro, I can only get All Core Overclock stability at 4200 Mhz, using 1.35V (with some thermal throttling). (I also get 4100 @ 1.275V and 4000 @ 1.2V with no throttling) Looks like my specimen is not a great example.?
3. I disabled PBO in my motherboard, but apparently this does nothing, as RyzenMaster, CPUZ, and CPUID HWmonitor, still show the chip boosting to 4.65GHZ and using 1.48V, which I dont like. Is this really OK for long term durability (this PC may be 3d rendering for days at a time)
4. Is it a common feature in a MB to limit the vMax to say 1.35V if PBO is enabled - thus limiting PBO boost clock, but allowing for a bit of a boost (I'd be OK with a boost of 4.4, I dont care about the few microseconds of 4.7 if its eating voltage to get it)
5. Under high Overclocking, I hear a slight random clicking noise. At first I thought a cable was clipping a fan blade, but extensive checking and manual fan override testing reveals no such interference. What else could be causing the (faint) clicking. It doesnt appear under stock conditions. Something on the MB, or PSU? Its very hard to determine where it comes from. For now I am keeping to stock speeds.
Thanks
