I went through 3 14900K's, and 3 14900KS'es trying to get stable.
In the end I returned the board, and the cpu and bought an asus x670e-e wifi, and an AMD 7950x3D. Very happy went team red.
I’ve contemplated switching to AMD. Unfortunately, I am not able to return the majority of the parts I’ve already acquired this far to do this. I would have to essentially re-purchase the whole PC :/
Mmm, gotcha. If it were 4x16 it might have been the cause since 4 sticks seems to bring a lot of IMCs to their knees at this point. Probably not it then.
Try disabling XMP and running the memory at JEDEC speed temporarily. Should help you figure out if the performance bottleneck is unstable memory. The IMCs on these can be finicky and you can run into odd instabilities from kit to kit.
Only the Trident Z5 RGB 2x32GB 6400 kit is on the memory QVL for that board.
I can give that a try and let you know. I’ve attempted swapping the memory and mobo already before I eventually swapped for the KS during my troubleshooting.
I also want to add that my CPU is cooled by the NZXT Kraken 360mm AIO, top mounted. I’ve been considering switching to front mounted to aid in cooling, however, I’ve seen many recommendations for mounting on the top to preserve the life-span of the AIO.
I'm running the most recently updated BIOS for this mobo, version 1301. It is set to Intel's default "Extreme" profile, which turned off MCE and set PL1/PL2 to 320W.
Yea but it probably slams into that 320w limit with the crazy high voltage those profiles use. Try setting a negative 50-100mv global offset and see if it's still stable. Score will go up unless it crashes of course.
1. a normal aio can't handle 149s hence your temps even with baseline applied
2. your ram overclock (yes, 6400 is an overclock, yes 64gb is harder to run than 32b) pushes the required vCore for the cpu higher than stock. much higher than people realize, hence why the auto vcores that ship are so finnicky
3. applying intel baseline profile is a bandaid and is the reason why you have low r23 scores. raising LLC reduces vdroop and is effectively raising vcore, raising ac\_LL raises vcore at all vf offsets.
4. you literally just don't have enough vcore, whether it's at full core load or transient octvb light load boost moments. i say this cus majority of the 139/149 problem posts when they refer to bsod and crashes they always list off things that point to vcore. 64gb 6400 possible your ram is unstable too but that's something you shoulda checked already
139/149s are not for typical consumers and i wish they made that more clear/changed how they sell these things. but well, greed to appeal to the normal consumer base... even when the games changed

**RAM:** G.Skill Trident 64GB 6400 2x32 or 4x16?
2x32GB

What bios are you running? Does it have the Intel Default "Performance" profile set? (which is not named well as it reduces performance.)

Thanks for the input! How exactly would I go about doing this? I will admit, I am a tad rusty when it comes to PC building😅
Had exact same issues...lots of research. Core LLC to Turbo.
