X370 Taichi with Beta L4.64

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

Yes I got it stable. I did not try the latest BIOS (or I have, but went back immediately) so I am using 4.81 beta for X370 Taichi. I just saw that there are new versions (5.50 the latest from this week). Up until few weeks ago I was checking FW releases, other newer boards were getting updates so I thought that there won't be updates for X370 until Zen 2. 

I will probably get one of Zen 2 CPUs and have to upgrade then if 5.50 is not good now, I will have to try it.

On 4.81 my settings are:
XMP, DRAM Frequency: 3000, Stable Mode, CPU Vcore Voltage -0.10000 (automatically sets this), CPU LLC Auto (Level 5), VDDCR_SOC Voltage 1.05000, VDCR_SOC LLC Level 3, DRAM Voltage 1.405V, VTT_DDR 0.710, else is on Auto.

Timings:
16-17-17-17-36, then 3-56-6-8-38-Auto-Auto-Auto-Auto-Auto-525-390-240-then all on Auto till CR 1T, Gear Down Mode Auto, Power Down Enable Disabled.

I didn't want to sqeeze it further, for me it's enough, after so many tries. This is stable, I had PC running for more than 3 weeks in a row, without BSOD, until Windows update had to restart:)

I hope this helps. I will try v 5.50 when I get more time.

	Hello, there! It seems we are in the same ship. I cant go above 2666 MHz with this memory - Corsair Vengeance LPX 2x16GB DDR4 3000 MHz CMK16GX4M1B3000C15 ver. 5.39(Hynix), Part Number: H5AN8G8NAFR-TFC, A-die. Here is [URL=https://www.overclock.net/forum/11-amd-motherboards/1626011-my-experience-asus-prime-x370-pro-918.html#post27940720]my reply[/URL] in another forum. Cuba1hr, so almost a year later what is the results, anyting different? Did you make this RAM to work stable at 2800 MHz? If "YES", can you give the full RAM settings(timings, voltages, etc.)? I tried so many settings and this model(MK16GX4M1B3000C15) seems to be cursed by all the gods and can't work above 2666 MHz on AM4 motherboards. Nobody takes blame - nor AMD, nor Corsair, nor motherboards manufacturers. They just not put this RAM in QVL and that is, so sad. Wasted money. Shame.

	Just an update - those changes mentioned earlier didn't help. Two days and BSOD, this time during the day for a change.

	Thanks for the advice, I already had SOC set to 1.15, but I was getting bsods (how many times have I written bsod or bsods here:)) I decided to lower it to mentioned voltage. I will give it a day or two with my last 2T settings and then try to increase VSoC and LLC. First I would try that advised settings with 1T. http://www.w3.org/2000/svg">

	I would set your SOC to 1.15v and LLC to 2

	Damn! Another BSOD, hal.dll this time. Almost got to 4th day. It restarted just before 2 a.m. Set 2T now and Geardown mode - Disabled. No noticeable change in performance in AIDA memory benchmark. Other settings - DRAMV 1.38V, SoCV - 1.0625V, SoC LLC 3, 16-18-18-38-56-530, don't remember others but settings way higher than what Ryzen Dram Calculator 'SAFE' recommended. Now I am the point of Never again for ASRock. I am so frustrated and mad at them and AMD! So many sleepless nights with unusable computer. I regret spending so much money to get nonfunctional piece of $hit. There's new freaking agesa, bring the new bios and get your $...stuff together! Going to try to sleep now. http://www.w3.org/2000/svg">

	As far as I know 4.40 is the most stable version up to date if you are on the last year Ryzen, but I cannot use it with newer CPU.

	At 2133 it works fine, 2666 was the highest speed I could get before UEFI version 4.40 - the last time I tried. At 2800 also no go as I mentioned in earlier posts. In my case 2T makes it even worse, Geardown disabled all the time. I will leave all settings as they are right now and if I get another BSOD in day or two try with 2T change only.

	ASRock support is really poor about communicating with their customer base. 1.0.0.3 has been out for a while now, and I've heard some really good things about it as far as audio issues and games crashing immediately when overclocked using all-core or P-state. In short, it doesn't happen with the newer AGESA 1003. I'm hoping they'll release something soon.

	@Cuba1hr Have you tried running the RAM at 2133 or 2400 MHz with all other settings on auto? If so, does your PC crash at these RAM speeds also? When running the RAM at 2800 or 2933, have you tried changing the command rate to 2T and disabling Geardown mode?
