Aorus i9 12900k build

[A1200]

Around this time last year, I put together an i9 9900k based system. See the build log here. Just over a year on, I thought it would be nice to do another. I got too impatient to find some DDR5 - I don't mind paying early adopter rates but I am not giving a scalper a thousand dollars for 32GB RAM. Additionally I like the DDR4 LPX RAM when using the NH-D15, as I can leave the second fan on the "push" side of the cooler.

Will put together in the coming days or weeks depending on what time I get.

First step, I have installed some LED strip lighting on the visible end of the front fan plate and in the void at the bottom of the case. In my previous build, I used the same strip lighting but mounted it to the top and at the motherboard side of the front fan plate. Be interesting to see the difference between the two. Have also mounted all the case fans. That will do for today, little and often.

i9 12900k, my first LGA 1700 install. Motherboard now in place and cables beginning to be routed.

[A1200]

Noctua NH-D15 and Corsair HX-1200 installed. More cabling in place. An air cooler of this size is an ugly beast but for those like me with liquid anxiety, it's the best thing out there. Going to clean up and I will put the GPU in tomorrow all being well. It's so big, getting the power cables and USB port cables connected means running them into the front of the case at just the right height.

[A1200]

GPU installed and front facing cable management complete. With the cooler and GPU, you can barely see the motherboard!

[A1200]

Rear cable management taken care of. The CPU power cables are just too short for a PSU of this length which moderately bothers me having to channel them diagonally but I am a believer in function over form any day of the week. So whilst I could use cable extensions, the added components that creates additional points of failure, however small the risk, I just will stick to the original cables on their own. I always try to do a good job on cable management, I hope this build is no exception.

[A1200]

Couldn't resist seeing if it posts and it did! Too tired to even plug in a keyboard to start setting it up but at least it's working so far...

[A1200]

Ok UFEI config, OS install, benchmark and bench tidy left to do.

 

 

[A1200]

All the peripherals connected, ready for the OS install, some moderate overclocking and some benchmarking.

[A1200]

Last of the images. Gone all white on the RGB for now, clean look. Will post a bunch of benchmarks to conclude this build log when I have done them.

[A1200]

Here are the revised benchmarks after I upgraded the RAM to DDR4 4000MHz C18. I found there was a slight improvement in performance but there was little to no memory overclocking potential beyond the XMP profile whereas on the 3200MHz rated memory I started the project with, I could tweak a lot more.

 

I found a good technique when pushing 5.1-5.3GHz all core on the P-cores was to leave the E-cores on Auto so they could clock down when not required, and hopefully keeping adjacent P-cores and overall package temps at the best the can be whilst still allowing the E-cores to do their their thing when required.

 

The GPU had very limited overclocking headroom as it is an OC card as standard - generally I was +100 or less for the boost frequency.

 

All fans set to 100% whilst running benchmarks. Some nasty temps @ 5.2/5.3GHz on some CPU tests such as Cinebench multi core test which reached 100c on 4-5 cores within the time of a multicore test, indicating the Noctua NH-D15 is fine for normal use for the i9 12900k but for serious overclocking this CPU really does require liquid cooling.

 

These are genuine observations - settings tweaked to suit each benchmark individually. I purposefully kept the room very cold - we are talking single digit ambient temps for a lot of these tests, this PC is located in hobby room which is a converted garage meaning with no heating turned on, in the winter it is easy to get the room down to almost outside temps!

 

Where there was no pre-set, or where I wanted to compare to settings I used on my previous build, I have stated the settings used.

New benchmarks based on changing RAM to 4000MHz kit.

[A1200]

Update, I upgraded the RAM to DDR4 4000MHz C18 (18-22-22-42) but on initial tests I didn't see any significant jump but running all those benchmarks is a bit of a chore so I will only post any significant improvements I discover as and when I check a given benchmark tool.

 

Edit: Redid all the benchmarks in the end, see previous post for new results.

Benchmarks completed.

very nice and clean build my friend. 

is that monitor 2k 27", i think it is. if so good choice. i have been running a 27" 2K monitor for a few years now and 1440p or more is the way to go.

Nice and clean build, hows temps with that NH-D15?

Hi yes 27"  165Hz - I run one on each of my rigs.

All core 5.0GHz fine - all core O/C at 5.1/5.2 and on heavy loads it hits 100 degrees. After benchmarking I usually drop to defaults anyway as its plenty of powerful enough. So basically, stock its fine, overclocking not quite.

Finished the build off with my first ever gaming chair. Corsair TC70. Nice quality feel to it.
