Without reading every post the only thing that I can think of is your mobo . memory is easy to exclude bit mobo nearly impossible

Seems problem fixed by using https://www.techpowerup.com/download/techpowerup-throttlestop/

Tip found at : https://linustechtips.com/main/topic/531278-skylake-system-stuck-at-800mhz/

Disabling BD PROCHOT shoots the core freq up to what it should be....and all of a sudden I'm at 90-100fps again :)

Learn something new every day!  Thanks Kevin for following up on the resolution to your problem.

Temps are showing max 32C over all cores, but the interesting thing is the CPU doesn't seem to be working harder than 800MHz?

Running realbench and monitoring with CoreTemp and CPUZ it showed no increase over 800MHz

Running P3D, I had the same issue...no increase above 800MHz, temps max 34C

 

Enter BIOS and set frequency manually. If that doesn't work switch off CPU thermal monitoring. There was an issue with some boards throttling back when they shouldn't. Shouldn't be left off permanently of course.

 

Have you installed latest BIOS? Very important.

Unticking Enable Away mode in AiSuite has also fixed this for some people. Do the same in the Power tab.

saga not ended..

I was getting horrible temps from the 2nd chip so decided to take the cooler off and redo the TIM.  This I did and it booted ok.

Then I did something so wrong I dont believe I did it - I tightened the CPU cooler screws while the system was running...

BAM, everything powered down and I got a Qcode 00 again.

I took the CPU completely out and reseated it, set the cooler in again, and now the mobo is showing Qcode 18 consistently :(

mem controller, try to reseat the cpu one more time.

power off complete, disconnect all cabeles from PSU.

I somtimes test that cpu is ok after delidd or something other, power on with a aircoller only hold it down with a finger.

Hi Kevin,

- You can check on the BIOS if the “Enhanced Intel SpeedStep® Technology” enabled. If it is, please disable it.

- Are you sure you didn't enable the slow mode switch on the motherboard..

Reseated another time, still code 18...

Cant access UEFI with the code 18.  Slow mode switch definitely OFF

a couple of years ago i have problem to booth when swap cpus on a 1150 gigabyte MoBo ( had swaped cpus 20-30 times on that mobo)

i get it alive with putting very little force on the cooler , it had problem with contact to the pins , when applying higer force it not booth.

think your problem is contact to the pins , bent pin or the pcp on the cpu is bend , that was one problem with the 6700k.

try a orginal Intel cooler and lock for suspect pins on the mobo and that the pcb on the cpu is straight.

here is a bad examle

many thanks for your ideas :)

Ive looked at the pins closely and there's only one I could see when the image was zoomed in where the pin might possibly be very very slightly out of alignment, but it is so minor that I couldnt be sure if it is a problem or not.

I may try reseating again but ever so slightly differently, before attempting to mess with the pins.

Would a bent CPU PCP be fixable?

Cheers K

Deliding CPU's although seems easy can be a pain and could kill a CPU, im afraid your symptoms look to me like a dead CPU, first thing i would do is to try another CPU there...

I find it hilarious how people say how great Intel are, then they risk destroying their CPUs to fix serious design flaws. AMD users don't have these problems. ;)

It's my opinion, this delidding is Voodoo Mechanics. I run a 7700K @5ghz at less than 60c, far less. The risk of damage doesn't out weigh the gain.
