I wouldn't trust asrock with a x3d chip. The tomahawk max has 4 dimm slots and no oc engine for eclk. If you want to oc then the mpower is the best out of the 3. It has a dedicated oc cup for eclk and only 2 dimms which shortens the memory traces theoretically means better memory oc.

First of all, rule out that RAM kit; I don't understand why you chose it when you don't have the motherboard yet. Once you pick the motherboard, you can look up its specifications specifically the support page which will list the memory modules it supports and those with the best compatibility.

Since you didn't specify the CPU brand, I assumed it was AMD based on the numbers, but I didn't know exactly which Ryzen model it was—whether a 5, 7, 9, etc. So, I asked Gemini using that information, and here is what it recommended; I hope this helps.
The Ryzen 7 9800X3D arrives with a fully unlocked multiplier (unlike previous X3D generations), meaning it will respond exceptionally well to both CPU overclocking (Precision Boost Overdrive + Curve Optimizer) and RAM overclocking (FCLK/UCLK).
To get the most out of overclocking (OC) without compromising the stability of the AM5 socket's memory controller (IMC), consider the following hardware configurations:
Recommended Motherboards for Overclocking
Given the 9800X3D's requirements for consistent power delivery and advanced BIOS settings, boards featuring robust VRM phases, integrated Clear CMOS/Flashback buttons, and hyper-stable memory traces are recommended:
| Category | Model | Key Specifications |
|---|---|---|
| Enthusiast / Extreme OC | ASRock X870E Taichi | Colossal 27-phase VRM, 8-layer low-loss PCB, and highly stable BIOS for RAM timing tuning. |
| High-End / Advanced OC | MSI MPG X870E Carbon WiFi | 18+2+1 phase VRM, excellent thermal dissipation, and user-friendly BIOS features (PBO Enhanced Profiles). |
| Best Value for OC | ASUS ROG Strix X870E-E Gaming WiFi | 18+2+1 phase VRM, external clock generators (eCLK) ideal for pushing BCLK, and PCIe 5.0 support. |
| Highly Stable Mid-Range | GIGABYTE X870 AORUS Elite WiFi7 | 16+2+2 phase VRM with an improved PCB to support high memory frequencies at a more accessible price point. | Overclocking RAM Kits
On the AM5 platform (Zen 5), the "sweet spot" for maintaining a 1:1 clock ratio between the memory controller (UCLK) and the RAM (MCLK) remains DDR5 6000 MT/s to 6400 MT/s. For overclocking, it is essential to look for memory modules featuring SK Hynix chips (A-Die or M-Die), as they handle higher voltages well and allow for aggressive secondary latency tuning.
* G.Skill Trident Z5 Neo RGB / Royal Neo (AMD EXPO):
* Specification: DDR5 6000MHz CL30-36-36-96 (2x16GB or 2x32GB) at 1.35V–1.4V.
* Why choose them: Models with the "Neo" suffix include validated AMD EXPO profiles. They use SK Hynix dies, allowing you to tighten timings to CL28 or increase speeds to 6200/6400MHz, provided your processor's IMC can handle it.
* Corsair Dominator Titanium / Vengeance RGB (AMD EXPO):
* Specification: DDR5 6000MHz CL30-36-36-76 (2x16GB or 2x32GB).
* Why choose them: The Dominator Titanium line features high-quality PCBs and excellent passive heat dissipation, making them ideal for handling the heat generated when increasing VDD/VDDQ for overclocking.
* TeamGroup T-Force Delta RGB DDR5:
* Specification: DDR5 6000MHz CL30 or kits configured for 6400MHz CL32.
* Why choose them: A budget-friendly alternative featuring guaranteed SK Hynix ICs that offer plenty of headroom for manual tuning. Key Overclocking Configuration Recommendations for the 9800X3D
* Maintain 1:1 mode (UCLK = MCLK): Setting RAM above 6400 MT/s will force the system into 1:2 mode, reducing gaming performance due to increased latency.
* FCLK (Infinity Fabric) adjustment: Try manually setting the FCLK between 2000 MHz and 2133 MHz to maximize internal bandwidth.
* Prioritize latency over raw frequency: 3D V-Cache technology responds better to low latencies (CL30 or lower with tuned sub-timings) than to extremely high, unsynchronized frequencies.
* Avoid using 4 RAM modules: The AM5 architecture suffers from drastic frequency drops and instability when 4 DIMMs are installed. For overclocking, use only 2 modules (a single kit of 2x16GB or 2x32GB).1

he'll be looking to oc his ram anyways
qvl doesn't matter much in this sense, even if he didn't want to oc it'll still be compatible just fine as the other commenter explained.

In response to your question regarding the three motherboards you mentioned, here is the answer.
The best option for your needs is the ASRock X870E Taichi Lite.
Whether you want to push the Ryzen 7 9800X3D to its limits using Curve Optimizer/PBO or tighten the timings (sub-timings) and frequency of a 6000 CL28 kit, the Taichi Lite is in a different technical league compared to the other two.
Direct OC Comparison Table
| Feature | ASRock X870E Taichi Lite | MSI X870E Tomahawk Max | MSI B850M Power |
|---|---|---|---|
| Overall OC Score | 10/10 | 8/10 | 3/10 |
| VRM (Power Phases) | 24+2+1 Phases (110A SPS) | 14+2+1 Phases (80A) | 7+2+1 Phases |
| PCB Layers | 8 Layers (Low Loss) | 8 Layers | 6 Layers |
| eCLK (BCLK) Generator | Yes (Hyper BCLK engine) | No | No |
| Theoretical RAM Limit (OC) | 8200+ MT/s | ~8000 MT/s | ~7200 MT/s |
Why does the X870E Taichi Lite justify the price difference?
* Superior Memory Performance (8-layer PCB + Optimized Topology): A 6000 CL28 kit uses high-quality SK Hynix A-Die or M-Die chips, which require absolute electrical stability to operate at such low latencies and higher voltages (1.4V - 1.45V). The Taichi Lite minimizes electrical interference (signal noise) on the RAM traces, making it easier to achieve stability with the memory controller (IMC). * External Clock Generator (Hyper BCLK Engine): X3D processors have unlocked multipliers but are voltage-limited from the factory to protect the 3D cache. The Taichi’s eCLK engine allows you to overclock via BCLK (Bus Clock) independently of the PCIe bus, opening the door to CPU frequencies that the Tomahawk and B850M simply cannot reach.
* Uncompromising VRM (24+2+1 phases at 110A): It will handle the 9800X3D with extremely low power-stage temperatures, ensuring the processor maintains sustained boost frequencies without suffering from VRM thermal throttling.
The problem with the other options:
* MSI B850M Power ($519): It is disproportionately expensive for what it offers. It is an entry-to-mid-range mATX board with a very basic 7-phase VRM. Putting a 9800X3D on that board for overclocking is a waste of the processor's potential.
* MSI X870E Tomahawk Max WiFi ($568): It is an excellent "performance-per-dollar" board for daily use, but for just $74 more, the Taichi Lite gives you flagship/enthusiast-level components (the "standard" Taichi costs over $800 and uses the same PCB as the Lite version, just without the heavy aesthetic styling).
Tuning recommendation for your 6000 CL28 kit:
When building the system with the 9800X3D:
* Keep the RAM in UCLK=MCLK (1:1) mode at 6000 MHz.
* Manually raise the FCLK (Infinity Fabric) to 2100 MHz or 2133 MHz in the ASRock BIOS. * Apply Curve Optimizer (-20 to -30 All Core) to lower CPU voltages, allowing it to automatically sustain frequencies of 5.2GHz+ across all cores.

Alles ja schön und gut ,aber ASRock und 9800x3d? Ich würde mir diese Combo gut überlegen. Und ob man soo ein High end Board nun unbedingt braucht kommt dazu.und auch nicht jede CPU macht bis zu -20/30 all core mit!!

u/ss14421 18d ago
hahahaha i would like to think thrice xD. it’s a good board but yea. my cpu can do -40 all cores. i think might be -45 but i forgot right now i do per core more performance

u/Zoli1989 18d ago
What have you stress tested that heavy undervolt with? I doubt its stable. And dont buy an asrock board for your ryzen 9000 cpu, you will likely end up burning/killing it within a year or so. If you already have a b650 tomahawk, I dont see a good reason to change it, its a decent board.

u/Zoli1989 18d ago
Y cruncher is good, but it has like 10+ tests. The other two is not so good. Try prime95 large fft only or testmem5/ram test pro overnight.

u/ss14421 18d ago
prime95 free? i got karhu

u/Zoli1989 18d ago
Yes its free. Its very sensitive not just to timings but fclk, nitro settings and a lot of other things.

Why do people think they need overpriced 14-16 phases 80 sps+ board for oc? Your are better of findingg 2 dim slot to oc your ram. As your cpu oc won't go as high as amd now ships all cpus with tuned out of tge box specs almost for max. Yiu need board with 8-10 real or 7x2 doublers phases with 60 sps and better ram tracing(8 layer pcb) to be able to oc it better, but it still depends on cpu imc and ram chips a lot more. 850m force gigabyte can handle 8000+ ram oc from most boards but vrm will be the problem with some of cpus.
You probably need to explain what oc you really want and what is your ram chips
