Read my post on it and you'll have my opinion. Bottom of the previous page (101). The ASRock X470 Taichi will be the last ASRock board I ever buy. Their BIOS support is atrocious.

First post here, as I am having great difficulties getting my computer with the X470 Tachi to POST after installing BIOS version 3.90 due to upgrade from a 2700 to 3900X. Pressing the power button will start the fans at full speed for at least a 2 to 3 seconds if it works, or the fan will continue at full speed perpetually. Cleared CMOS twice, once via the button behind, and once taking out the CMOS battery. Both did not help. Saw some advise in another forum saying to increase RAM voltage, but did not resolve the issue as well. I did not overclock the CPU, and the RAM was running fine with the 2700. In fact once I boot into Windows, the system is very stable even under stress test on CPU, memory and graphic card. So I rule a faulty or unstable hardware as the issue. So that leaves me with the doubt if the BIOS is causing this instability. I've seen some fairly similar comments here, so just want to reconfirm if this is a normal scenario?

Check my Sig below for my system details

Hi I have a motherboard problem, it takes him a long time to get to the Asrock logo. And until it gets to the logo, the monitor doesn't turn on either.
The problem started when I updated the board to the new version 3.0 + CLR CMOS

The board shows me the following codes in a cyclical manner:
A. 14,15,33,61,63,92,94, cc, c8
B. cb1.98, b4.02, c5
I tried lots of things to fix the problem.
Change version to the one I was in before 2.7
Run with the default settings
Work with one stick of memory

Another problem I want to ask .. How to set up video card will work on PCIE 3

I don't think ASRock Tech Support checks this thread guys. If you have specific
queries your best bet is to contact ASRock Tech Support:

You can also keep an eye on JZ's website for Beta BIOSes. Once they are on his
site the release is typically not too far off.

I was wondering if anyone else here has used EK monoblocks with their Asrock motherboard and what their experience was? Did you encounter particular problems? What was your satisfaction using the block? What kind of temps did you have? This is my first custom loop.

I have x470 Master SLI/ac with a R7 3800x and EK ASRock X470 Gaming K4 RGB Monoblock (that also works with this motherboard). I think it performs well with much better VRM temps over the stock heat sinks.

Perhaps a disappointment I have with it is the amount of CPU coverage with the block is somewhat less than I expected. Compared to the Corsair H100i 240 AIO it had that had 100% coverage of the CPU. I'd say approx 15% of the CPU doesn't get covered by the cold plate part of the EK block which I didn't understand from the picture before I bought it.

I wonder if this partial coverage is part of the reason under low CPU utilization lower range temps tend to bounce a lot between 38c to 48c? However my high usage temps tend to stay under 70c.

Previously with the AIO my low CPU utilization just hovered around 38c (not much bouncing) and my high temps were 78c. In my new config I also have rx5700 in the loop with EK CoolStream PE360 so the comparison isn't exactly apples to apples.

The 2nd disappointment is the RGB cable is about 1mm too thick or the RGB connectors on the main board are simply too close to the other connectors to comfortably insert them. Either a connected fan is blocking or too close to CMOS reset pins makes using these parts of the board difficult and perhaps prone to break something.

Overall I've been very happy with this board since December 2018. Had a few ups and downs with RAM overclocking over different BIOS versions but once 64GB of ECC was working I was happy (Special thanks to ASRock & the memtest86 people for helping make that possible with Zen2!).

For what was often a $135 newegg special motherboard I think it worked out just right with the balance of features and options. Unfortunately by the recent AMD news it seems Zen3 won't be possible with this board after all.

Some constructive feedback regarding general issues...

1) The fan headers at the end of the PCIe slots for GPU's is absolutely terrible placement unless say it's a 90deg fan headers. I uncomfortably squished fan connectors with my GPU until I got fed up and modded this part of my board when my new GPU block just couldn't fit because of this.

2) About 1mm extra spacing around RGB and D-RGB headers would be nice for those unruly RGB cables whose ends are somehow stupid wide.

3) A few general purpose temp sensor headers would be nice so the built-in fan BIOS/UEFI control can be used with liquid cooling temp sensors.
