Suddenly not booting with all cores enabled

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   As to my skills, I have masters degree in electrotechnics and my job is to program (and sometimes help design) embedded systems, but I'm mainly programmer and this is my first build in years, so I do not know how exactly some things on motherboard / in CPU work or what the "normal" state of components / values should be.
On the main page it says 3500 MHz. 
CPU Config page:
Target CPU / Cache / BCLK speed    3500 MHz / 3900 MHz / 100 MHz
Memory speed   2133 MHz
FCLK 800 MHz
everything else Auto, everything is default nonetheless
CPU Microcode revision: 506E3 74
As to the cooler, I think I'm not over tightening it - it doesn't have normal screws, only some plastic holders and I'm trying to fixate it there as gently as I can.

	Here is a gallery of photos of CPU and temperatures of some components of VRM in Celsius (if I'm not measuring the right thing, please let me know): https://drive.google.com/open%3Fid=0BynchtWoOt7acVBMMTdXNnh0SzA CPU substrate is not bent (after I read some post, I was afraid it could be, but luckily it's not), nor there are any visible burnt or bent pins, or at least I don't see any yet. When I reinstalled everything, it's still the same, it only boots with max 3 cores enabled in BIOS. Edited by wildfireheart - 10 Jan 2017 at 4:20pm

	I would pull the CPU and check for warping and bent or burned pins.

	DO NOT TOUCH, yet run the backs of your fingers over the VRM section. Hot by chance? Scalding hot?

	Hmmmm In the main page of the BIOS what does it say the processors Ghz is? Too look in the CPU Config page and note the numbers there too. Odd. Has over tightening the TX3 crossed your mind? Sorry, for I have no way of knowing your knowledge and experience here over the net in as many printed words is present.

	3, because I have 3 enabled in UEFI (I have graphs for CPU - Total, Service CPU Usage, CPU 0, CPU 1 and CPU 2).

	Hmmmm.... One more please. Run the Command resmon, get over to theCPU tab, how many cores are graphed/shown at the right?

	If you mean UEFI version, then it's P7.00, I did automatic network update when problem started, didn't help. Yes, setup was working fine for about a week, no high temperatures, everything normal and stable. After that, two days ago, I started the computer after it was turned off for a night, booted into Win 10, started "Adware Removal Tool by TSA", it run up to 10%, then froze, I did hard reset and it won't boot with all cores since. I checked the system with 3 cores after that - no adware or viruses found. When it broken down, RAM was in B1 (I was too lazy to reattach fan to the other side of the cooler), currently it's in A2, but I tried all other slots. XMP profile didn't help either. Memtest found no errors, so I assume memory is fine. Edited by wildfireheart - 09 Jan 2017 at 11:23pm

	On the intro page of entering the BIOS, at the top, what BIOS rev is the board flashed to? 3.40? How ling ago was it the system was built? 1 week? What slot do you have the lone stick of memory residing in?

	I have everything set to "Auto", I never intentionally overclocked anything so far. When I run tests in Windows (with 3 cores), the frequency is 3.5 GHz as expected. When I run same test with 3 or 4 cores in UEFI version of IPDT, I get 4.665 GHz, so I think this could be just wrong reading.
