I'd go through the standard checklist:
- CMOS defaults
- Reflash the latest BIOS
- Check the pads on the CPU and double check the socket for bent pins
- Let it crash a few times, note the timestamps, then swap the CPU for a good one and check the Windows logs.
The 5960X is on the supported CPU list for the X99S Plus, therefore it shouldn't need any manual voltage tweaking. If it does, something is either defective or worn out.
I have a feeling your CPU might have seen some rough handling and is on it's last legs, hence you have to increase the cache and SA voltages.
it freeze after booting.
-CMOS defaut, already done,
-Didn't do that, but I try to reinstall my Xeon e5-1660v3 and it's work fine.
Now, i am running prime95 (2H30)(with the 5960x at 3.3 ghz) with everyting(AVX2 and FMA) and the system didn't crash yet.
with 1.05V on SA and ring, the system crashed right after i start prime95.
with 1075V on each, i ran prime 95 for 20 minute, didn't crash.
I run now at 1.1V just to be save.
my cpu isn't overclocked for now, i just want to be sure it's stable.
with that in mine, is the cpu broken or the motherboard ?
Ps: holy cow this cpu is power hungry, with only 0.95V, it's consume as heat as much as my xeon e5-1660v3 at 1.05V at load(both stock 3.3 ghz). i am not sure my xeon could run at 0.95V stable at 3.3 ghz
LLC is one step below max.
my cooler is an evga CLC 280, one the best cooler that i can put on my case, but i am already at 63C in prime 95
