CPU upgrade

[Dave2602]

Hoping someone can help, I have a omen gaming PC with the Blizzard l 894A motherboard, it currently has a i5 12400f CPU, according to the website I can upgrade to an "i7 14700" which is what I have done, but when I have replaced it and gone to turn the PC back on, it turns on for 1 second and turns off. The bios has been updated with the latest firmware using HP support tool, I have had to put the old CPU back in. Can anyone help with why it's not turning on

@Dave2602,

Welcome to our HP Community forum!

Your OMEN by HP 25L Gaming Desktop PC GT14-0000i (3V745AV) as fitted with the BlizzardL motherboard (SSID: 894A) according to HP's BlizzardL motherboard specifications should allow 12th, 13th and 14th gen processors: https://support.hp.com/us-en/document/ish_5799854-5799957-16.

However, I haven't seen a single HP System OMEN by HP 25L Gaming Desktop GT14-0xxx (BlizzardL) User with either a 13th or a 14th gen processor: https://www.userbenchmark.com/System/HP-OMEN-by-HP-25L-Gaming-Desktop-GT14-0xxx/266169, and neither does HP PartSurfer for the HP OMEN GT14-0xxx series show even a single PC offered with either a 13th or 14th gen processor: HP PartSurfer.

Meaning, regardless of HP's BlizzardL specs, it appears that HP has not yet released a BIOS update to make 13th and 14th gen processors work in your OMEN by HP 25L GT14 desktop.

The best processors, at the moment at least, are: i7-12700 / i7-12700F, both with a 65-watt TDP and a "Maximum Turbo Power" of 180-watt.

I see no reason why the i9-12900 and the i9-12900F -also with a 65-watt TDP and a "Maximum Turbo Power" of 202-watt, wouldn't also be compatible with your gaming PC.

NonSequitur777, Thank you for your comments, it doesn't really help after spending £300+ on a CPU I am being told should work and is compatible.

This page https://support.hp.com/us-en/document/ish_5799854-5799957-16 has been showing it supports this cpu for over 6 months. is there anyone @HP can help?

@Paul_Tikkanen,

Sadly, the only 'flag' option I am given is to "Notify Moderator of Inappropriate Content".

@NonSequitur777 

That's where you input your request.

Anytime you need to contact a moderator for any reason, you flag the post.

It does not have to be due to 'inappropriate content.'

@Paul_Tikkanen,

That is good to know!

Must have dozed off during Flag 101.

I flagged the OP's post accordingly.

You're very welcome, @NonSequitur777 

I'm sure this was probably discussed before your tenure as a HP Expert.

Cheers, 

Paul
