[SOLVED] Compatibility check

[XPRDGY]

Wanting to get an i5 9400f in place of my i3 6100.

Rest of my parts are:
Gigabyte GA H170 D3HP mobo
x2 Gskil 8gb ddr4 ram
Zalman ZM 400 GVN
Nvidia Gtx 950 2gb

What other parts would I need to change /upgrade to have it all be compatible with the new cpu?

 

[SteveRX4]

Motherboard and maybe ram.
The motherboard needs to list the 9400f on the CPU QVL.
And the ram on the memory QVL

Okay cool, how come the RAM?

RAM doesn't always work on all motherboards.

You can't use the 9400f on your Mboard, Refer to this CPU support : https://www.gigabyte.com/Ajax/SupportFunction/Getcpulist?Type=Product&Value=5521 .
You need new Mboard if you want to use the 9400f.

This makes no sense. The older i5-9400f with a b365 board will cost about $235 and give you 6 cores / 6 threads.

You can get a new Comet Lake i5-10400 with 6 cores / 12 threads and a B460 board for about $280.

Use of your exisiting RAM with either system depends on compatibility.
