Hi again,
just to let you know that my machine didn't even make it to day 3 of uptime on 2800. Got BSOD at 5 a.m. today - Memory_Management again. I'll try 2800 with 16-18-18-36-54, VDIMM 1.37V, VSOC 1.125V, LLC3. Cannot practically use my PC year now. 1 bad memory stick and two Gigabyte faulty boards (B350 Gaming 3 and X370 Gaming 5)...ended up with Taichi. It was a tough choice between X370 Taichi and Asus ROG Crosshair VI WIFI...and... maybe, I made a wrong choice. I haven't tried the other one. Earlier today it was 14-16-16-34 on 2800, all on 4.64 BIOS. |

So, about a week on and here are my observations:
1. RAM is no more or less stable (with my kit) than 3.0 I was using before the update. 2. RAM latency and R/W speeds are more or less identical to what I achieved with 3.0 3. RAM speeds and timings achievable with the Beta are the same as 3.0 (3333 max stable @CL18) 4. Benchmarks show absolutely no change I was stable at 3466 on my RAM for about a week then began experiencing the occasional blue screen. With some looser timings I can stop those but at CL18 my timings are not great to begin with so I just dropped to 3333 and set my timings to CL16. Bugs? CPU temps read stupidly high in the UEFI. I am sure there are more but that is the only one that stands out as a potential issue (for some users). A lot of people get scared when they see high temps in the UEFI so this is something that needs addressing IMO. Still fine tuning and tweaking. I have yet to do any CPU overclocking, honestly I generally run stock on this system with my poultry GTX 960 there really isn't any point in overclocking anyway.

I am not familiar with 3.0, in shop they installed 3.20 I think when they tested board with my 1700X and my Corsair - they have said it was stable on 2933 (tested for 1-2 hours I guess) and then shipped the components to me. I had troubles with RAM on that version. Soon there was 4.40 bios and after so many tries on that one it was stable for earlier mentioned 13 days (windows update restarted my computer then). I cannot reproduce that situation with 4.64 or 4.70 and cannot go back with 2700X. Now the PC is running for 2 days 15hours, raised DRAMV for 0.01V more (1.38V, shown 1.40 in picture), tomorrow morning is the critical period, if the patient survives early morning, it will live:)...but I doubt, every time it's the third day BSOD, just after problem with NTP update...I think. I have seen that in my event viewer before "unexpected restart" few times, don't know if it is correlated, but error more than 90% of time is MEMORY_MANAGEMENT and few IRQL_LESS_OR_NOT_EQUAL. Here are problematic MIN & MAX values in CPUID HWMonitor and HWInfo on BIOS 4.64: |

Hi guys, again.
This time PC managed to go through 3 days and today before 2 a.m. I got another BSOD, without Bug Check String, just ntoskrnl.exe. I am so crazy. I even turned off NTP as a percaution. I pumped DRAMV up to 1.40V now and VDDCR_SOC to 1.0625V. It used to be on Auto and 1.125V earlier if I recall correctly. Timings for 2933 are as they were: 16-18-18-18-38-56 Increased tRFC to: tRFC 514 tRFC2 382 tRFC4 236 and ProcODT is all the time set to 80. Anyone with better idea or suggestion, I would appreciate it. |

Of course. New Windows 10 installation on formatted SSD after every MBO change. Last time I tried Memtest there were no errors. I cannot test freaking thing for hours (8-9 I think) on every single change in UEFI. It passes memtest to get BSOD after that.
It takes time to test 32GB. There used to be errors on some tighter timings (below 16-18-18) then when I tried at 2133 everything went OK for 4 passes. Now when I make a change in UEFI, I run AIDA64 stability test, memory only (other things passed fine earlier) for about an hour. If some setting it doesn't like, it usually stops the test or BSOD within 5 minutes of start. I am mad because it passes memory test, works for 2-3 days under load & then BOOM! Why the freaking thing passes memtest to crash after 3 days... I woke up because I heard it idling (on welcome screen), cursed it again and set up UEFI at 4.30 this morning, running stability test till 6 a.m. and went to work. I go through same procedure every second or third night. I was unaware of this problems when I bought RAM in early April last year when Ryzen just arrived. I paid about 285USD year and some ago so I don't want to wait till it's sold (I was selling my 1700X for over a month and lowered my initial price by 100$!!!) and lose money to be getting the "same" thing (OK, faster Samsung? 2x16GB) I already have for almost 550USD...and still 16GB modules are dual rank=problems again (or lower speeds, higher timings). I could get 2x8GB but I need more than 16 for VMs and other things. My 6-7 year old PC has 16GB. I was even thinking of 64GB when prices normalize one day but more than 2 modules bring another handful of problems on Ryzen platform. For an year I was hoping, first at Gigabyte camp, now at ASRock's for them to do something for us suckers with Hynix. But still nothing - 14 MONTHS!!! They did something positive on 4.40 and then screwed everything up again (I blame both AMD & ASRock). I still follow Gigabyte forum, there's still not grass greener on the other side either. |

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.

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.
