Bonus build while waiting for the remaining parts (update: benchmarks!)
While waiting for all parts I've been working on repurposing my 2400G for a HTPC build, together with some spare parts.
The 2400G is still a very capable chip and I felt like I didn't really do the APU justice in the ghost with the 1080,
so I figured this would make a good opportunity to see what it can do without a GPU and a decent OC.
This deviates from the purpose of this thread, so I opted to put the write-up on this in a spoiler.
For those interested in the 2400G, read on 
[SPOILER="2400G - bonus build & overclock benchmarks"]
- Mobo: AsRock Fata1ty Gaming-ITX/ac
- CPU: AMD Ryzen 2400G
- Cooler: Wraith Stealth + NF-B9 from the ghost's NH-L12
- Case fan: NF-F12 from the NH-L12
- Memory: 1(2)x4GB HyperX Fury 2666CL15
- Storage: SanDisk X600 128GB M.2
- PSU: HDPLEX 160W DC-ATX + external 180W AC-DC adapter
I was able to put this build together mostly from parts that I already had laying around.
I've had the metis for a while without having a specific use case (?) for it, and the HDPLEX PSU was intended for a different build that I never got around to building.
The external PSU & M.2 were also spares that came from a Dell G5 that I no longer own, but I had to get the motherboard and the memory for the occasion..
For cooling I was able to repurpose the stock cooler that came with the 2400G.
I also was able to put both fans that came with the NH-L12 to use.
The stealth turned out to be a little bit too loud for my liking, so this is where I was able to utilize the NF-B9 92mm fan that came with the L12.
In short I unscrewed the original fan shroud and used zipties to mount the NF-B9 to the heatsink. It worked out better than expected!

Bonus build update and benchmarks
Still waiting for parts (b-die availability struggles), I decided to elaborate on the build I've been working on in the meantime.
I was very impressed with the single 4GB stick I picked up for this build.
Its rated at 2666C16, but I was able to clock it to 3200C14 w/ tightened subtimings fully stable!
Because the APU is so starved of memory bandwith, this yielded pretty good gains in terms of GPU performance.
I decided to try my luck at the silicon lottery, and picked up another stick to see if I could achieve the same speeds in dual channel configuration.
Unfortunately, the new kit did not only not clock as well, it also had a different type chip.
The first kit was Hynix AFR, while this one was a Micron variant. It was not stable at 3200C14.
My own fault for not buying the kit in pairs, but it should be entirely fine as long as they can handle the same timings.
So with a whole lot of trial and error, I was able to get a decent overclock on most parts.
I could probably have pushed it slightly further, but at this point I think I'd start seeing diminishing returns in terms of time spent/performance gained.
Memory subtimings were tightened using 1usmus DRAM calculator.
The OC is stability tested for my use case using Furmark, in-game testing, CB20 R20 and HCI Memtest.
I was able to clock the GPU to 1600MHz and memory at 3200CL14, but unfortunately neither was stable enough to my liking.
Final overclock
CPU: 3.9GHz @ 1.3V
GPU: 1500MHz @ 1.2V
RAM: 3200CL16 @ 1.35V (16-17-18-18-30)
SOC: Auto
| Benchmark | Stock | Overclocked |
| Cinebench R20 score | 1821 | 1916 |
| Firestrike 1.1 score | 1773 | 3607 |
| CPU-Z ST score | 439 | 448 |
| CPU-Z MT score | 2377 | 2424 |
| Overwatch (Avg. FPS) | 51 | 63 |
| Overwatch (Avg. 1% low FPS) | 36,5 | 37 |
| Apex Legends (Avg. FPS) | 42,5 | 50,5 |
| Apex Legends (Avg. 1% low FPS) | 30 | 29,5 |
Game benchmarks is an average of 3 games.
No extreme results here, but when you're already playing in a low FPS range, a ~10 FPS increase in average is really noticeable.
In the end I'm very impressed with what this APU can do. Can't wait to see what AMD does with their APU's next year, with navi and their chiplet arch.
