14700K, Intel XTU says Overclocking not supported

[NickKz]

I am running an HP Z2 Mini G9 which supports this cpu

 

There is no option to enable XMP in bios or to enable overclocking at all

 

Intel XTU in Windows has pretty much every option greyed out and says overclocking not supported

 

Voltage control is also totally locked out, so I can’t even undervolt

 

I am wondering why HP even sells these with K series cpu support at all, I mean what’s the point?

 

Would I have been better off getting the non K 14700?

The motherboard is the problem then.

Even an H chipset board supports K suffix CPUs, CPU support is an Intel thing

but for why HP sells overclockable CPU on a system that doesn't let you do that, honestly they don't care because someone is going to just judge the product purely by the names and not investigate deeper.

Most certainly, unless you are willing to move that CPU over to a DIY build later where those options will become available.  Although I'd argue the HP is going to be bad no matter what if it wont enable XMP that every CPU supports.

Thanks for the responses.  I was actually considering using it in another build down the line, so I guess it’s not a total let down.  This board uses a W680 chipset.

 

I am using ECC (these sodims specifically https://www.crucial.com/memory/server-ddr5/mtc20c2085s1tc56br?_gl=1*1mhrhu5*_up*MQ..*_ga*MTYxNzAxNzgwNy4xNzE0NzkwNDAz*_ga_6H4RYWV7QY*MTcxNDc5MDQwMi4xLjAuMTcxNDc5MDQwMi4wLjAuMTU2MzU5ODg1MQ..) memory, if that matters at all…they are rated for DDR5 5600…but they are only running at 5200 at the moment.  They ran at 4800 with an

older i5 12500 cpu.

 

I am not too familiar with how XMP works or the ins and outs of overlocking, but I suspect HP just wants to charge an additional fee for people wanting the K sku CPUs, and they basically lock them down to whatever pre set settings they have in their bios configs.  Oh well.

HP sticks to Intels guidelines for their Pro, Elite and Z lineup. When you run those CPUs on actual Intel stock specifications the k CPU will outperform the non-k by quite a bit after the turbo timer runs out because PL1 of the k is 125w and 65w for the non-k. 
 

Consumer DIY boards tends to completely ignore the turbo timer and run PL2 all the time, in this instance the k and the non-k will be pretty close. 
 

5200 is listed in HPs specifications as maximum supported memory speed for 32GB DIMMs

Thanks, that’s great info…but for the memory speed, I still don’t get.

 

They list 13th gen here https://h20195.www2.hp.com/v2/getpdf.aspx/4AA8-2412ENW.pdf#:~:text=ECC SO-DIMMs-,• 16 GB PC5-4800E Single Ranked 4800 MHz DDR5,rank 16 GB based DIMMs

 

But I believe on 14th Gen, the speed is supposed to increase to 5600 MHz for dual rank dimms?

 

The Z lineup was just updated to support 14th Gen so that’s why it’s not listed in the documentation.
