Glad you stopped by, welcome!
I just wanted to get the ball rolling with support for enthusiast level ASrock X570 motherboards. I wont be listing out features since reviews have been done to death, instead this thread will be about overclocking the motherboard and getting the most out of it. Furthermore, if you have any issues this is a good place to talk about them. I am in direct contact with people at ASrock who can make any necessary changes and release bios updates.
I have had a chance to play with the X570 Taichi combined with a 3700X, so I'd like to share some of the things I have learned and start the discussion. I am using the latest 1.60 bios, which is available on the support website, and also listed below. As for support equipment, I am using 2x8GB Samsung B-Die memory, an AIO cooler, and a basic GPU for display output.
As you probably know by now, the rated boost frequency on the box of your Ryzen 3 processor doesn't necessarily mean your CPU will do that for all cores. Today I am looking at what CPU overclocks can be accomplished by manually setting all cores. I wont be covering 24/7 stability by running days of Prime95 or anything like that. For testing I will simply run Cinebench R15 several times for a given frequency and voltage. This is what I would consider benchmark stable, which is different from 24/7 stable.
I was able to accomplish the following:
Precision Boost Overdrive
- Precision Boost (Stock Bios): 4200 MHz All-Cores @ ~1.40v
- Precision Boost Overdrive (Maxed limits): 4200-4275 MHz All-Cores @ ~1.40v
- Fixed: 4100 MHz All-Cores @ 1.15V Fixed (LLC1 = 1.15v Load, max temp 55c)
- Fixed: 4200 MHz All-Cores @ 1.25V Fixed (LLC1 = 1.26v Load, max temp 59c)
- Fixed: 4300 MHz All-Cores @ 1.35V Fixed (LLC1 = 1.37v Load, max temp 67c)
- Fixed: 4350 MHz All-Cores @ 1.45V Fixed (LLC1 = 1.47v Load, max temp 78c)
In order to let the motherboard take over and overclock your CPU to the max, you first need to set the limits of the Precision Boost Overdrive (PBO). In the picture below I simply entered maximum rating which would be impossible for the CPU to attain making the PBO limits functionally disabled. Letting the motherboard take control of the overclocking is more efficient with power management, but potentially not the best in terms of maximum overclock. For more information about precision boost and precision boost overdirve, there is a nice YouTube video linked at the bottom of this thread.
The important thing to note is the VID voltage located in the above bios screen shot. Leave this field alone and don't adjust the "Vcore" voltage here. When you enable manual overclocking, the VID voltage will be set for you, mine is 1.1000V. In the screenshot below you can see I setup Vcore and also the Load Line calibration.
The CPU overclocking may have been quite boring to some of you, but the memory is where the real fun is for Ryzen 3. The XMP rating of your memory might not work for the AMD platforms, because in many cases they are optimized for Intel platforms. ASRock has done us a kindness and included some memory profiles in the bios to get you started.
As of right now, there are three memory profiles loaded with frequency, timings, and voltage all setup for you. I tested the profiles with very old Samsung B-Die, very Samsung new B-Die, and also Hynix M-Die. They work flawlessly and should be excellent for daily use.
Please tell us in this thread how much you like the memory profiles...maybe we can get ASRock to include MOARRR profiles!
The built-in profiles were a nice touch, and they certainly help you get going quickly. However, if you are like me, you will want to tweak the memory for maximum performance. In my early testing, I was able to create two 'benchmarking' profiles that work really well for various benching tasks.
There are a few critical bios settings beyond the typical stuff that can really aid memory overclocking and overall benchmark efficiency.
High Frequency CL14
Below is the timing profile I created for CL14-13-13-13. I was able to boot and run all benchmarks easily at 4400 MHz using this timing profile. If I loosen up the secondary timings a bit I was able to train 4600 MHz. However, it was not stable for all benchmarks. With more testing and tweaking I believe 4600 MHz might be possible with CL14-14-14-14. The voltage for this profile is 1.75 V, with 1.15 V SOC.
Super Tight CL12
Some benchmarks prefer very tight primary timings. While I think high-frequency CL14 might be the better option for most tasks, sometimes CL12 is the best bet. The highest I was able to train was 3866 MHz using this super tight profile. When starting out, I found it was easiest to first train 3600 MHz in order to train the bios with the timings. Once 3600c12 has been established, then you can make attempts at high frequency. Here is the timing profile I came up with for CL12-11-11-11. The voltage for this profile is 1.75 V, with 1.15 V SOC.
- SOC Voltage: Values between 1.15 V and 1.20 V can help stabilize the memory
- ProcODT: Values between 38 and 60 have been known to help. On Ryzen 3 I have found that values around 40 Ohm are optimal for daily use. The conventional 'safe' limit for extreme overclocking is around 60 ohm.
- Gear Down Mode: Disabling gear down can dramatically improve benchmark performance, but might be more stressful for memory. I highly recommend disabling this before you even get started stressing memory.
- Infinity Fabric: For the best efficiency you want this as high as you can. Typically it will run about 1800-1900 MHz. If left auto, the infinity fabric will be 1:1 ratio with memory frequency, up to 1833 MHz. Beyond DDR4 3666 MHz memory, the ratio will be 2:1. For now we will leave it there...
Please Note: You may need to limit the memory in the OS to make this work. Windows has a built in feature called maxmem to accomplish this.
32GB (4x8GB) V.S. 16GB (2x8GB)
The motherboard is exceptional at overclocking four memory modules. With minimal effort I was able to run both of the profiles above while having all 4 memory slots populated. I noticed that four memory modules required about 100mV extra when compared to just two memory modules.
ASRock X570 Phantom Gaming X Motherboard (Current X570 Flagship)
To my admittedly limited knowledge, this is the same motherboard as the Taichi except it includes Phantom Gaming 2.5 Gigabit LAN as well as the Intel Gigabit LAN.
