Processor incorrect identification

[Casomme]

I upgraded the CPU to an i7 4790 on my 800 G1 SFF but the BIOS and windows identify it as an i3 4790. The CPU does not turbo boost past its 3.6ghz base clock but all 8 threads are listed in device manager. I have the latest BIOS and chipset drivers.

Here is my system information:

OS Name: Microsoft Windows 10 Pro

Version 10.0.18363 Build 18363
Processor Intel(R) Core(TM) i3-4790 CPU @ 3.60GHz, 3600 Mhz, 4 Core(s), 8 Logical Processor(s)
BIOS Version/Date: Hewlett-Packard L01 v02.77, 17/04/2019

Any ideas on fixes?

EDIT: the pcie x 16 socket stopped working and I had to move the GPU to the pcie x 4 slot. I then put the i5 4590 back in and the pcie x 16 lane started working again and is working as normal. I am going to assume the CPU is defective.

Thanks

Hello

which was your previous CPU ?

do you mean  that even entering  in BIOS setup , pressing F10 at boot , the CPU is identified as Core i3 in System Information page ?

did you try, after doing a BIOS setting backup , to do an Apply Factory default or a CMOS reset ?

If BIOS continue to show it as I3 , for sure Windows will show the same.

Hi,

Previous processor was an i5 4590.

Yes even in F10 Bios under system information it says i3 4790 @ 3.6 ghz. Which is amazing since it has never existed.

I have set BIOS to default and done a CMOS reset with no success.

hi ,

never heard about an issue like this and you already have latest BIOS version.

Core i7- 4790 was supported by Elitedesk 800 G1

I'm sorry I can't suggest anything more.
