[Success] b1's "Mac Mini Killer" with macOS Mojave: i7-8700 | Gigabyte Z370N | RX560 | 16GB RAM

[petro]

the solution is quite simple
from system preferences
Boot disk

Can someone please shade some light on SMBIOS variations for this Mother Board like should we choose
Mac Pro 1,1 and other variants
iMac 18,1/18,2/19,1/19.2

 

[petro]

I have always used 18.1 and currently 19.1

Hey,guys! I came across a good deal on i9 9900k and made a decision to get it.

Spoiler: swapping cpu

I didn't change anything in EFI, and it just works, right away recognized by system.

I've started to benchmarking it and compare to my previous i7 8700, expecting it to be crazy hot, so I thought I'd get a second fan for my Black Ridge CPU cooler, but surprisingly it runs cooler than i7 8700 and the performance isn't the greatest - but better than i7 8700.

Spoiler: cinebench r23 i7(left) vs i9(right)

the geekbench 5 score also isn't really overwhelming.

Spoiler: geekbench 5 i7(top) vs i9(bottom)

I noticed that Intel Power Gadget shows maximum TDP right below 95W(for i9), so I guess there's a power limit set. Just to be sure I checked benchmarks under Windows 10 - same.

So gotta disable TDP power limit, tried to google it and found how to do it in BIOS under M.I.T, "advanced cpu core settings" changed "Package Power Limit" from auto to 150watts (just to see if there's a difference), also changed "core current limit" to higher value. And nothing changed in terms of TDP. Will do further research for sure, but maybe some people can relate to this problem?

I see that @petro uses i9 9900k in his build, did you do anything specific to unleash the power of it?

Hi here

Just a thought ...

Did you check for an updated BIOS version that might make compatibility with 9th gen better?

Hi, honestly I don't think this is an issue. I'm on F13 version now, F10 introduced 9th gen cpu's support, F11,12,13 description mention enhancements for CPU, but 14b, 14 are all about other things.
Gigabyte z370n BIOS updates

 

[petro]

connect the processor and before update the bios
I have not done anything else since I am left over with this processor
I bought it since it was the maximum that this motherboard supports
What I have noticed is that the bios takes longer to boot than with the i7-8700k

 

[serg1892]

connect the processor and before update the bios

My bios is F13, not sure whether it's safe to update to anything newer.

I bought it since it was the maximum that this motherboard supports

same here

What I have noticed is that the bios takes longer to boot than with the i7-8700k

It seem that booting into BIOS takes the same time comparing to my previous i7 8700(non k).

May I ask you to test your CPU with Cinebench R23 and monitor via Intel Power Gadget? To see whether your CPU wattage consumption goes above 95W?

the tdp of the processor is 95w

 

[serg1892]

the tdp of the processor is 95w

Yes - You are absolutely correct, it's listed as 95W... But it's never true actually. Just for example - my previous CPU i7 8700(non K), listed TDP by Intel is 65W, lets see what it will show under full load on Cinebench R23:

Spoiler: Intel Power Gadget i7 8700(non k)

So it's almost 90W without dropping all the time, my cooling is enough for its not to thermal throttle.

Let's compare the scores again,
Geekbench 5(single/multi core):

i7 8700 1096/6632

i9 9900k 1198/7667 +9%/+15%

Cinebench r23(single/multi core):

7 8700 1124/8678

i9 9900k 1200/10023 +6%/+15%

@petro If you'd compare your previous i7 8700k to your i9 9900k you'd see even less overwhelming results.So in your case you basically didn't get anything significant after switching.

i9 9900k known to be as a very hot CPU, and some people say that it reaches 300w consumption at spikes sometimes with other manufactures mobo's , but normally it goes around 150W for short periods of time which is ok IMO. And the Geekbench 5, Cinebench R23 scores from other people online on average are 10-15% higher than in my case. And I'm not even talking about overclocking.

So there's something in our z370n holding its power.
