Hello people

so i was of those who recieved the earliest batch of 8700k cpu and have since had issues which i think seem related.

Specs:
8700k
X. Hero motherboard
850 evo ssd 256gb
1tb WD blue
3200 dominator platinum ram.
Evga 750g2 supernova PSU
1070 evga ftw
H100V2 AIO
Crystal 570x case
Windows 10 fall creators update


Firstly: everytime i turn on the pc whether Cold boot or NOT it switches off after appx a sec or 2, in that time everything seems to start to boot (fans spin,board lights etc) until when it goes through the first of the QLED's (cpu) is is solid red (normal i think) by then it switches off for a sec and reboots and the first led ( cpu flashes 3 times then moves to the others which flash once -orange ,white and lastly green and all boots up fine! Although slower than my 4770k hero 7 system

Secondly and the main concern or affect on my use is that the cpu stutters in my games where also NOT getting almost any heat that i feel out of case from the h100 v2 cooler AIO.

The heat sink radiator pipes radiator itself even running prime or aida 64 still barely warm not cold but not warm however never any apparent throttling and tests will run

Games will play although i get big spikes and almost all the time like very suttle stutters most apparent when firing weapon and the rifle feels hard to control due to this also. Sometimes vary's the amount of stuttery feel

Tried new PSU,different gpu (titan x maxwell) reseated cpu couple of times with new thermal paste pea size amount! Tried every build from anniversary update onwards reinstalled windows many times should mention that setting different fan profiles low or high performance has at most 1 degree difference otherwise i notice no affect. Have tried my old system antec aio in this system same thing. I get the feeling as though the motherboard is not giving the correct voltage to cpu or something but am clueless here guys pls help!

VCCSA and VCCIO can be "picky" with certain CPUs. These voltages also don't scale better with higher voltage in some cases. This means that to much can cause stability issues just like too little. There is a "window" of stability. You really shouldn't need that much voltage for 3200 from my understanding. I"m running 3200 CL14 and I manually lowered the voltage after enabling XMP. The XMP can add a bit more than necessary which adds extra heat and could potentially cause issues if a bit excessive. For myself, I manually set my VCCIO to 1.05v and VCCSA to 1.15. I've ran the usually stability tests, including Memtest86, at these settings. I believe XMP set both to 1.15 or possibly 1.2 for each, but I'm not totally sure. These...

Ok. I would switch MCE off until this gets straightened out. I would try booting with minimal hardware to narrow thgat down. 1 RAM stick, remove GPU all together, only have OS drive connected. When this double boot occurs, what is the 2 character Q-code displayed on the motherboard LED?

thx for keeping im touch really appreciate this , when it first attempts boot it hits 00 then switches off 2-3secs then comes on with cpu light flashes twice at both flashes the numbers land at 25 then it moves to ram vga and then boots fine to A0. Will definitely remove the hardware as you said out of the case properly tommorrow was actually thinking this. However will have to be in the morning as little ones are fast asleep and it's like 1:30 am at night one thing i forgot to mention was that if i keep shutting down and powering on again and again in succession it will not boot twice but that doesn't seem to be the case if left for a while more than the way mentioned above or if switch off from the back of PSU and back on again it will boot twice even during the succession repeated shutdown power ups ....hope this sounds normal i am so tired should stop reading up in this and get a couple of hrs sleep:D

Code 00 means the CPU isn't working, or isn't being recognized by the motherboard. You can also see if for a split second at the end of shutting down your PC. A0 is normal boot from a cold boot, where 40 is normal wake from S4 sleep when shutdown in Windows 8 or 10 with Fast Startup enabled.

ok what i have done before bringing everything out of the case i removed gpu,1 of the ram sticks of 2 and noticed while doing this that my motherboard was loose at 2 screws bottom left corner so i tightened them and so far i thought i would test a few times giving rest in between.
Well there is no more of the booting twice atm and i noticed the red cpu led no longer flashes but just lights steady once and very quickly moves to ram led.

Now i attempted to test the cpu under stress test for the issue where there is no heat from cpu cooler and this problem is still occuring.
I noticed one thing during stress test and that is the fans initially ramp up and the temps say 80° after a few secs (appx 3) fans let down and temps say around 60 using prime or AIDA same issue but from begininng to end of stress testing the air around pc case, inside out ,pipes from h100 ,radiator ,fans ??? How is there no heat yet running tests with no throttling detected able to run the games even if stuttering.

I do also notice that cpu usages seem strange for eg without mce on games like bf4 use 25 to 30% and only one thread is being utilized in task manager where i know in my other system it would use almost all cores all threads and around 55% usuage

Would further point out that during the last bios update i had to do it through the ez flash in bios as the USB at the back would not flash it

I am really worried that all these tests are destroying my cpu. Indeed my whole system possibly if i continue this way.

Edit just try booting again and now the boot twice issue has re occured ...????

If this is still occurring without GPU, 1 stick, different PSU, different cooler, OS reinstall, ect. I feel its either a board or CPU issue. I have seen folks on here having 8700k failures, though in general CPU failures are quite rare. Being that it occurs with latest UEFI, minimal hardware, all stock settings in UEFI including XMP and MCE off reinforces this theory in my opinion. At this point, I think you would need to consider an RMA.

Regarding flash, I always use EZ Flash in UEFI, and never just the USB option from the rear IO port.

Ok i will go with RMA but would i need to try both or RMA motherboard first or cpu first, in your opinion what do you feel i should try at this stage?

Also why when i would remove hardware and reseat cpu for eg do i get a msg "after setting intel optane memory or the raid configuration was built SATA mode selection must be changed to RAID mod3 to avoid unknown issues press f1 to run setup " any other problem here or is this normal ? Also my core voltage after again reseating cpu and making sure correctly reports in bios at 1.104 rather than 1.052

hello m8 pls can you help me. I did RMA the cpu...they found "overheating BSOD auto msg fault found.
so anyway they sent me a new one and at first it booted and cut off where upon restart i got cpu fan error (may not be installed correctly) i set it as disabled in bios and it now boots up all fine so far however i ran AIDA 64 and noticed again the temps climb to around 80° then after a few secs they go down to around 60 like before with the other cpu ..???? could it be the cooler also faulty, or maybe faulty cooler in the first place destroying my cpus? i am worried to use the PC at this stage in case i damage it

Can you relist the most current things you have tried? Are you getting any BSODS or errors with new CPU? Is MCE enabled in UEFI since the swap? What are voltages listed from stresstests with software like HWMonitor? What are you using to read core temperature? You need to remember that AUTO voltages on motherboards with 8700k tend to overvolt even at stock speed. This may still occur even with MCE disabled, so we would want to see what HWMonitor reports for speed and voltages. The temps you are reporting shouldn't cause damage. The CPU will throttle itself when approached 100C. However 80C sustained often may shorten overall lifespan a bit, but likely only by a small amount and only if this temp was maintained for hours a day.

bios: overclock tuner is set to auto, per core ratio.
running AIDA fpu voltages are 1.136 -1.68 for vcore
clocks 3.7 ghz all cores VID all cores around 1.1+v temps 58c power 95 w my worry here is that if i set to auto it will run at 4.7 but temps not be much higher. EVEN prime is running 50 - 60° c how ??? i was ready to pick your rma choice as solution but i am worried about this because it all seems like related possibly to another thing alongside faulty cpu

ok so i have noticed that if i run cpu test not fpu then voltage will go up at 1.264 and clocks go up all cores to 4.3 ghz but temps the same with fpu test 1.1 vcore 3.7 ghz.....i feel the cpu cooler is slighlty warm in any case definitely no hot air coming out but 1 pipe warm other not i live in england it is fairly cold but again these temps seem way too low.

Ok so i woke this morning turned on PC and found that the problem has occured again the PC is booting twice
now that this is occuring with a new CPU then and after the old one was found to be overheating then i think this is receiving the same problem from probably the motherboard, this could then mean i have damaged my cpu like the other one......?
update :
a user with similiar issue said in a thread he lowered xmp to 1600mhz ram and it was ok but that enabling xmp speeds would not supply enough voltage to cpu or something like this so i tried.

i did enable xmp after since i thought why not since everything seems fine. then the issue occured next time i booted next day

Setting the speed to 2133, 3 times i booted at 15 mins intervals between with no boot twice issue occuring.
still a joke to play bf4 then it is on my 4770k it is just not smooth at all very choppy

errmmm i dont' know where to find it but i went back into bios where VCCIO voltage says 1.328 - 1.336v
system Agent says 1.144 - 1.152v
Dram is 1.344 xmp enabled
sry i didn't see msg as i was running memtest for 4 hrs (no error)

These voltages at stock no XMP are .95 and 1.05 respectively. I would give this a try to see if there is any change.

hmm... very interesting, i tried that which you recommended by setting one of them to 1.2v instead of the 1.336 and now it is booting normally although the occasional random fine boots have appeared before it is looking positive but i cannot keep testing as it is like nearly 5:00am
i did noticed a brief period of heat coming from cpu cooler while runinng AIDA 64 which doesnt happen normally but it went away. temps running around 64c FPU only

here in uk i need some rest
Wow i am really curious about this.
I will post 2moro after i wake and test it all :) THANKYOUUUUUU for sticking with me you are very patient & kind!

so it is the next day and still with lowered voltage as you suggested still no double boot issue but a bit long during boot process particularly during vram led point where it hold for a few short secs then asus boot logo appears 3 times, after this system appears sluggish to type for a few secs in windows. Should i lower those voltages more ? i won't try unless yous suggest it

It shouldn't hurt anything to try a bit lower. Not sure how it would cause a bit of sluggishness on POST, but I can't say that it couldn't either. Just have to experiment. Again, I'm using even lower voltages than you, but with different kit. Also, you could adjust the POST/eventual voltages for DRAM itself.
