I am trying to upgrade my CPU on a Dell Inspiron 3847 Tower. One manual list three different type's of CPU's that may (or may not) have been installed on various desktop systems. My system contains the following:

System Manufacturer Dell Inc.
System Model Inspiron 3847
System Type x64-based PC
System SKU 0622
Processor Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz, 3400 Mhz, 2 Core(s), 4 Logical Processor(s)
BIOS Version/Date Dell Inc. A09, 1/25/2018
SMBIOS Version 2.7
Embedded Controller Version 255.255
BIOS Mode UEFI
BaseBoard Manufacturer Dell Inc.
BaseBoard Product 088DT1
BaseBoard Version A00
Platform Role Desktop
Installed Physical Memory (RAM) 16.0 GB
Total Physical Memory 16.0 GB
Available Physical Memory 13.1 GB
Total Virtual Memory 18.8 GB
Available Virtual Memory 15.5 GB
Page File Space 2.88 GB

A couple of years ago) I added EVGA 500w PSU along with Nvidia GTX 950 graphics card.

I cannot find any information on this Motherboard (manufacturer) or number that would link me to compatible Quad Core Intel i5 (4th Generation) upgrade. I have delved into the inner works and no soap. No other name listed on the board itself. So…......can someone point me in the right direction so I may complete this process?

here are the cpu's that you can put in that pc:
Intel Celeron
Intel Pentium Dual Core
Intel Dual Core i3 (4th Generation)
Intel Quad Core i5 (4th Generation)
Intel Quad Core i7 (4th Generation)
You can put non-k procesor's in there.

You can also use the 4790k for it's great single thread performance and extra cores:

Otherwise the other processors are just a slight boost and the added cores:

I have a 4790k in my 3020 SFF and it made a pretty big difference.

The motherboard supports up to an i7-4770/4790. I think you will need to update the bios to support haswell refresh CPUs like the i7-4790 or i5-4590/4690 which are also supported.
Thank you for the information. The BIOS upgrade is done after the installation of the CPU correct? Also…I saw somewhere that the CPU has to match LGA 1150 pin...correct?

You would update the bios first with the original working CPU still in the system before pulling it out and upgrading to the new CPU. You don't need to update the bios to support an i5-4590, i7-4790K or other compatible CPUs, since your bios version was released in 2018 and haswell refresh was released in 2014. You should be able to use any i5/i7 4000 series CPU.

Oh you almost always can. It's just usually not useful as there is no overclocking capability. In the case of the 4790k though with its base 4Ghz clock, it really is a big boost even in stock form.

Thanks for that info. As it turned out installed BIOS was ver A09. Updated to A11. Now I wait for the CPU to arrive to begin the upgrade process. ;)
