Finally finalized my AM4 setup after way too much tweaking, failed boots, and memory training loops. But I enjoyed the process, lmao.
The main specs:
– Motherboard: ASUS TUF Gaming B550M-PLUS Wi-Fi
– CPU: Ryzen 7 5800X + Noctua NH-D15S
– RAM: G.SKILL Trident Z Neo 2×16 GB 3600 CL16 F4-3600C16-16GTZNC (Dual Rank)
– GPU: Gigabyte RX 9060 XT 16 GB +100 MHz core / -75 mV undervolt, deshrouded with 2x Noctua NF-P12 PWM
The MOBO is bad, so bad I started loving it.
DDR4 OC
The RAM is Hynix DJR. Surprisingly, it hates higher voltages. I use 1.36 V at 3866 MHz.
I’ve been stuck at 3733 MHz for a long time because my 5800X has the classic 'memory hole' and simply refuses to boot at 3800 MHz. Interestingly, a few days ago, I managed to POST and boot at 3866 MHz, but it was horribly unstable. Still, that gave me hope that the IMC had more left in it.
After a lot of tuning, this is where I landed. Please see the second pic. And the resulting AIDA numbers on the third one. Unfortunately, tRDWR < 16 doesn't post. I tightened everything.
Besides the well-known DDR4 OC guide, the following one helped me understand the process: Infinity Fabric Overclocking on Zen2/3.
5800X OC
All core OC
I tested both static OC and PBO2 extensively.
The chip can do 4.6 GHz all-core at only 1.2 V, which honestly makes me think I got a pretty decent sample despite the IMC limitations.
For Cinebench and sustained multicore workloads, I actually think the static OC is the better option. Power draw was slightly higher, probably due to the constant voltage and clocks.
PBO2 OC
Eventually, I settled on PBO2 for daily use, with negligible performance loss for slightly better temperatures.
– PPT: 125 W
– TDC: 85 A
– EDC: 115 A
Curve optimizer values:
Core 0: -25 (3rd best core)
Core 1: -24 (best core)
Core 2: -28
Core 3: -27
Core 4: -27
Core 5: -27
Core 6: -24 (2nd best core)
Core 7: -28
GPU OC – RX 9060 XT 16 GB
Nothing too crazy on the GPU side. The real upgrade was the deshroud + Noctua mod. The card is basically inaudible now.
Current settings: +100 MHz core, -75 mV undervolt.
Rest of the Build
Case: NZXT S340 fans (top: NF-A15, rear: NF-P12, front: 2x NF-A15)
PSU: FSP Hydro PTM PRO 1000W Plat, the fan doesn't even spin until the system pulls 300W.
Monitor: Samsung Odyssey G5 32” 1440p 144 Hz
NVMe: Samsung 970 EVO Plus 500 GB, Apacer AS2280P4 1 TB
Peripherals: Microsoft Classic IntelliMouse, Cherry MX Board 6.0
Overall, I'm extremely happy with the setup now. Performance is great, temperatures are under control, and the entire system stays nearly silent even while gaming since most of the Noctua fans sit around 50%.
AM4 still has some life left in it. 🙂
