Hello all, I've been lurking on here for guidelines and tips of overclocking different chips and how people have achieved on different CPUs with their settings.
However, my board have been kinda acting weird and seemingly refusing to overclock at all so I figured I may have to ask for some help here.
My PC spec :
ASUS Rampage V Extreme X99 LGA2011-3 (BIOS 4101)
Intel Core i7 6950X
Noctua NH-D14 air cooler
GSkill DDR4 TridentZ 8x16GB [email protected]
Zotac GTX970 AMP! Extreme (1529Mhz Core and 2000Mhz VMem)
Corsair HX750v2 Gold PSU
Intel 750 SSD 400GB + Kingston SC300 SSD 120GB + 2x Toshiba 6TB, 1x Seagate 500GB HDD
Currently using an old Corsair 650D Case with a Noctua 200mm intake front, a 120mm stock case Corsair fan in between drive cage and GPU
2x 140mm fans intake from top and 1x 120mm fan exhaust at rear
This board is approching 5 years, but the 6950X is relative new (well...sort of). I purchased this 6950X from previous owner where his went post 00 and broke, and this was a brand new RMA sealed box back in August 2019.
I figured this may come in handy replacing my old 5820k which had been running at 4.1Ghz 24/7
The memory kit is also fairly recent which replaced my old Corsair 4x8GB 2400 kit
Now the PC would work fine if I only put my memory at XMP stats (3200Mhz, 100:133 ratio, 16-18-18-38-T2, 1.35V)
However, the CPU would never stay stable regardless of whatever I tried.
The CPU would read about 75 - 95 Degrees when running 4.0Ghz sync all cores during stress tests.
I've tried 1.21 Vcore at 4Ghz and it would randomly hangs roughly 12-24 hours uptime
tried flickering SA voltage from 0.95 ~ 1.15V and no stability matained
then I suspected maybe it is the Uncore 32 being the curplit but then I threw from 1.025 to 1.15 cache voltage, the system would still freeze up randomly without BSOD
I made sure my voltages were sufficient to let the CPU run Prime95, OccT without rolling out errors and they seemingly went on freely for 4~8 hours without errors....
until like 50% of the time when I wake up from sleep it would hang up during the stress test, others seemingly looked fine.
I also tried MemtestHCI and it had no errors at 3200Mhz, 1.00V SA after 400% pass.
Being so frustrated I decided to go a bit more agressive and try higher speed and see if that gives me a clearer error about what was going wrong.
At 4.1Ghz from 1.26 ~ 1.3 Vcore it would throw me random 0x124, with 50% of the time it gives me full dump file, 25% it stucks at 0%, and the rest mixed with either a blue 0x124 but event lot never show that bsod record, and simply freeze hang with no logs tracable....
Since all of the above Vcore and CPU speed I've tested showed the CPU is very unlikely to be good in overclocking I also tried to put some 2-3 AVX offset hopefully the CPU would run more conserative while OCed to 4Ghz and would behave more stable....except it would still freeze randomly after 12-24 hour uptime....
btw there was also one instance before where my PC crashed and refused to boot thereafter and I had to reseat the memory sticks and CPU to make it go back live.
Right now I'm kinda clueless on what I should do
The system is currently configured about at stock speed (35x with 1 core at 40x), and only run memory and uncore overclocked which are both at 3200Mhz.
This would allow the system to stay stable for more than 30 days 24/7 without crashes and errors.
I bought this chip hoping it would at least allow me to run 4Ghz for the next 3 years or so but right now I'm stuck with stock speed.
Now I do have to add that the mobo didn't came issue-free when I got it, as it was also a 2nd-hand item and the borad seemingly came with a faulty Bios1 chip which would post but never able to update or stay stable in Windows. I figured this would be hard to explain for an RMA and just went on by using the Bios2 for the rest of the days till now.
The Rampage V Extreme also appears to dislike all defaults settings and would randomly shut down itself and restarts whatever CPU the 5820k or the 6950X I throw in but that issue would be gone if I do the settings manually.
Do you think this would be the CPU's fault or that the mobo had some hidden defacts?
I'll include a screen cap of settings I am using atm which would stay stable
