Intel 14900KS fun!

[Bennehmaru]

Hi All,

Looking for some advice as I'm now about to install the 3rd 14900KS in a machine that was only built in May.

I'm using an ASUS Z790 Maximus Formula on the latest firmware, but have had instability on both of my previous CPUs.

I've now received the new CPU but wondering if there is anything in particular I should be doing, the board is using the current intel defaults as recommended on the board, with no overclocking or under/overvolting.

I'm just trying to ensure I've done everything I can before re-building the machine this weekend.

Thanks to all suggestions in advance.

I’m running a 14700K I bought here on the Members Market. The main thing I had to do to stop throttling was undervolt it using Intel® Extreme Tuning Utility. With the latest BIOS, which may lock the CPU to Intel specs, you just need to make sure VMX and undervolt protection are disabled.

Link to video not my youtube video, just he explains it also

Okay been taking a stab at this, I'm guessing the real goal is to stop thermal throttling?

I'm currently down to 57x on all cores with -.0060 on the offset, which is passing stress tests and getting me around 37000 in cinebench r23, does that sound about right? Goin on the video I was expect a 14900KS to get close if not above 40000.

stop overclocking... if you are.
if you have been through 3 cpu's id been looking at your motherboard choice, there is no way your that unlucky

I'm not overlocking at all, left the original 2 CPUs at intel default settings and kept the BIOS up-to-date too. Both of the previous CPUs had instability, which would end up crashing in games and also randomly closing applications like outlook and teams.

I'm underclocked and undervolted have a -0.065 offset at the moment and not getting any thermal throttling now, fingers crossed this will be the one.

So that's the thing, I've changed out the motherboard Asus Z790 Maximus Formula and changed out the memory kit too thinking it might be those, still eventually developed the same behaviour. Maybe I'm just the unluckiest person for CPUs at the moment.

I did think it might be the SSD at one point, but ran diagnostics on that and it's fine, it's really stumped me tbh!
