This thread was created for sharing general experiences, overclocking settings and results for the Z790 NOVA WiFi motherboard.

Key Features

Bios, Tools & Software
Updated: (12/05/23)
Bios: 3.01.BD02
Bios: 3.03.BD02
Bios: 3.03.BD04
Bios: 3.07.BD01
Timing Configurator v4.0.16
All official drivers, bios, manual, etc: Link

The OC relevant components of the test system are an intel i9 14900k (ES), 2x24GB DDR5 Corsair Dominator Titanium 8000MT/s CL38 and Watercool Heatkiller IV CPU water cooler with MO-RA3 420 radiator.

Let’s start the ambient overclocking, but first the results with default bios settings.
Image


Then entering the BIOS in advanced mode you will find in the OC Tweaker menu a new feature, the CPU Indicator, that shows you the OC quality of your CPU.

This works for Alder and Raptor Lake CPUs.

First, I tested if the motherboard is capable of performing a memory stability test with the XMP settings of the 2x24GB DDR5 Corsair Dominator Titanium 8000MT/s CL38 kit.

In the DRAM config I selected the XMP 3.0 profile 1
Image



VDD_CPU Voltage was set to 1.360V and VDD_IMC Voltage to 1.485V (voltage mode “OC Mode” must be selected in order to go above 1.410V VDD_IMC)
Image



The next screen shows a 500% MemTest run without error. That is quite impressive for a 4-dimm motherboard at 8000MT/s CL38.

Image


In the following OC examples, the cpu p-core ratio was set for all p-cores to 58, all e-cores to 46 and 50 for the cpu cache ratio. The cpu voltage was set to fixed mode at 1.275V, VDD_CPU at 1,36V and VDD_IMC at 1.485V.

First OC Results with memory XMP settings

Image


For the next result, I simply changed the following timings to manual values in addition to the XMP profile.
  • Write Recovery Time (tWR) 10
  • CAS Write Latency (tCWL) 28
  • tREFI 262143
  • tCKE 8
Image


These timing adjustments helped boost scores in all three benchmarks.

Image


For the next test, more manual adjustments were done on the memory timings and the voltage had to be increased for VDD and VDDQ to 1.57v.

Image


Image


Image


Image


This helped again to boost scores in all three benchmarks.

Conclusion remarks

Even though the NOVA is designed for gamers, it is still a great overclocking motherboard. The ability to use high frequency memory is great for a 4-dimm motherboard and it handles memory overclocking well and easy. It is simple to navigate through the bios and I really like the new CPU indicator feature. Let’s see how sub zero overclocking works with this motherboard, our ASRock testing team will keep you updated.

Cheers,
Tomi

That Board looks interesting. :love:
QVL Memory list 8400 DDR5.
Nice. More than Gigabyte new MB.

Maybe i orderd one for testing. :unsure:

No, only 8000 XMP was 500% HCI MemTestPro stable. But I still learning. Today I tried my old green 2x16GB A-Die sticks and it was possible to run Geekbench3 at 8400 CL34.

Geekbench3 result

This is awesome @noliso , ddr5-8400Mhz on a 4 dimm motherboard was unheard off until now 😁 , great job bro. ASRock is doing so good with ddr5 overclocking.

Tomorrow i will be testing Team Group DDR5-8200Mhz 2x24Gb kit on the NOVA, will post here my findings , tweaks , tricks and ddr5 overclocking with the settings i will use for everyone to see and get them a starting point with ddr5 M-die 2x24Gb kits.

ASRock Z790 NOVA in the house. Arrived a couple of minutes ago via UPS with a 14900K. Testing incoming 👌

This Mobo it's heavy and built like a tank. It has a backplate that also doubles as a heatsink to cool the 20+1+1 vrm , memory back area and back of the chipset. 8 layers pcb optimized for high memory clocks.

Stock xmp , stock everything out of the box boots ddr5-8000Mhz. Voltages and everything are stock settings xmp 😄Have not touch anything. I'm on a air cooler on the cpu ,just boot it up and first boot straight from bios Boom 8000Mhz 😁.

I'm going to install my water block now to give it a good test.

So, can this board get 8000+ vst/tm5 stable?

Bạn đang mỉa mai hay sao??
[/TRÍCH DẪN]
Are you being sarcastic or??
Please don't misunderstand me. My board is a budget board, it costs only 200 us. in that we only have it, otherwise I would have bought the ASRock Z790 Riptide WiFi which is 50 us more expensive, which is much better. I'm here to learn, most of my knowledge comes from you guys. I want to compliment asrock. And this is my 2nd day with this board, it is stable with 7400 on my old G.Skill 6400 MT/s

Tôi xin lỗi, tôi đã hiểu sai tin nhắn của bạn. Cách tin nhắn của bạn được viết ngụ ý với tôi rằng có vấn đề gì đó với bo mạch chủ, nhưng khi tôi nhìn vào ảnh chụp màn hình thì mọi thứ có vẻ ổn, đó là lý do tại sao tôi đặt câu hỏi liệu bạn có đang mỉa mai hay không. Đó chắc chắn là do sự khác biệt trong ngôn ngữ mẹ đẻ của chúng tôi. Tôi xin lỗi nếu tôi tỏ ra thiếu lịch sự trong câu trả lời của mình.

So far the Nova has been performing very well even on LN2. The overclocking in OS works really well, no odd coldbug behavior or anything like that.

14th gen IMC seems to be a little worst then 13th gen on cold, require very precise tuning for voltage, so far the most stable setting have been SA auto/ VddCPU:1,35V/ IMC:1.42, anything else has training issues, also keeping the memory warm helps a lot.


Given all its features, post code, power/reset button, good memory performance for the price this is one of the best board for overclocking.

Where you buy yours?

Until i found the setting for the SA-Voltage. (under FIVR: SA voltage mode)
it took me hours to find it. :ROFLMAO:

I used msi & asus in the past.

no stable performance with Viper Xtreme 8000 2x24 GB above 7600.
The edge z790i couldn't do it too.
so not worse or better than the edge.

M_Die 24GB seems to behavier different than A-Die.
i find more difficult than a\m-die for stable performance.

pro: the nova can handle the cpu frequency much better than the edge.

with my gskill 7800 a-die, i can do 8000CL34 on the edge.
that is the next big test & prove for the nova.

can it handle 8000CL34? (Bios 3.01.BD02)
we`ll see it ....
