I think i feel bad for my i5 7600k, in early reviews the gap was more significant at 1080p, not it's down to almost zero and in multi threaded games it demolishes i5/i7, more and whats most important it has alot of headroom while i5/i7 is often maxed out in many games... Well i will stick to that i5 for 2 years or so and jump the six/octa core wagon for sure 🙂

With 2800MHz Gskiill Ripjaws V, it works at 2933 as long as I am using just 2 x 8GB. I have the same experience with both an Asus Prime X370 Pro and Asrock X370 Taichi.

Just upgraded my BIOSTAR x370GTN ITX motherboard to the AGESA 1.0.0.6 update. It's all good. Got my HyperX Predator DDR4 3000 (Hynix 2 x 16, Dual Rank) to run using XMP at 2933MHz @ 1.35v (and Windows 10 now properly reports the RAM speed not the DDR speed which would be half). Stable overclock of R7 1700 to 3.8GHz @ 1.36v. Taking the memory from 2666 to 2933 made a significant difference, though on the old BIOS I could OC stably to 3.9GHz my CPU-Z bench @ 3.8GHz now beats the reference 5960X in both Single and Multithread. Before the BIOS update it beat it in multithread (not as significantly as it does now) and lost in single thread. Looks like I'll be able to stick with the BIOSTAR. Ryzen is great! Edit: I did add 0.1v to SoC. Also, this BIOS lists support for up to 4GHz RAM.

Haha I was JUST about to download the Chinese version of this BIOS update out of impatience (I heard it defaults to English on English boards). I'm excited to get my memory where it should be!

Now that I finally got my AGESA 1006, my RAM is now running at the 3GHz it was supposed to. I could get it to 3200, but not stable. However, my timings are in the 15s, so if I bump them up a notch I could probably do 3200 stable. My board seems to really hate it when I tamper with the Gear Down setting. I can leave everything else at defaults but just disable that, and the system is rendered unbootable. I feel like this could be part of why I'm stuck at 3000. CPU-Z claims my command rate is T1 when it should be T2. Then again, it also read the RAM voltage wrong.

Am sure you are quite aware that the only way to get 2T working is having Geardown disabled. Otherwise the CR is overridden to 1T.

I have heard of this, but like I said, if I disable it (even without changing anything else) my system is unbootable. If I disable it and set the command rate to 2T, it is still unbootable. I don't know what to do. The weird thing is before the AGESA 1006 update, my RAM was running at 1T, which is why I couldn't get to 3GHz. Now I can reach 3GHz, but programs like CPU-Z claim I still am using 1T. I don't get it. Ever since the latest BIOS update, RAM failures result in my entire CMOS being wiped, which makes experimenting with teaks a lot more tedious. The previous BIOS version would default to failsafe settings but I could still load any saved profiles. For now, I'm just glad my RAM is running at its advertised speed (well, close enough anyway). I'd like to OC to 3200MHz but I'm not going to push my luck. Apparently, other people have had a hard time OCing my RAM, even on Intel systems.

@ thatguy91 - just read this over at the ROG forum:

As of now, Intel has better compatibility over AMD ryzen. I don't know if this is a matter of bios or ryzen CPU itself that cannot support higher ram clocks over 3600Mhz. It is little disappointing that my DDR-4000 kit runs lower than its specification.

Its a limitation of Ryzen. It's also important to understand that memory kits are rated according the the platform they were qualified on.

The reply came from Raja. One of the ones on the ASUS bios team for the C6H. Take it for what it is worth. Do not know now if 3600 is possible to get stable on my cpu if 3600 is truly where it tops out.

Memory OC Showdown: Frequency vs. Memory Timings on AM4 platform Agesa Microcode 1006 Memory OC Showdown: Frequency vs. Memory Timings on AM4 platform Agesa Microcode 1.0.0.6 , a great read to understand the new values on the new Bios based on Agesa 1006 The release of AGESA 1.0.0.6 to mobo makers has resulted in a wave of fresh BIOS updates, each one packed with tons of new options for tweaking and overclocking memory. With so many options at your disposal, some have understandably asked: “what are the optimal settings for games?” Never one to leave an overclocking question unanswered, our illustrious overclocker Sami Makinen took his ASUS Crosshair VI and AMD Ryzen™ 1700 CPU for a spin to find the fastest combination of settings in a few different tests. Before we dig into the data, here’s what we analyzed: The impact of the new BankGroupSwap (BGS) BIOS option Single-rank DIMMs vs. dual-rank DIMMs Automatic sub-timings vs. manually-tweaked subtimings Max frequency vs. lower frequency at tighter timings Geardown Mode (GDM) on vs. off Complete detailed information here: http://forums.guru3d.com/showthread.php?t=412876&page=51 Source Link and complete report: https://community.amd.com/community/gaming/blog/2017/07/14/memory-oc-showdown-frequency-vs-memory-timings

Thanks Chispy it was a wealth of information. Only thing, why on earth did they not test GDM=disabled and BGS=enabled. It was either both enabled or just BGS off. Would guess that BGS is the new label for rank interleaving or an improved version of it.

Your welcome my friend , great read and a wealth of information indeed. This new information did spark on me a need to re-visit the latest Bios and find out what i can do in the memory overclocking department. 3466Mhz CL 14 tight timings seems to be the sweet spot 🙂

That may be the sweet spot but cannot quite get there yet. Currently able to get 3466 and CL15 stable with the F4-3600C16D-16GTZ kit. Based on synthetic benchmarks, was able to determine that the largest setting for interleaving size is favored; 2k just eeks passed 1k. METRO 2033 (not redux) appears to run smoother with both BGS options enabled and the penalty is ever so minor. EDIT: the settings are run with BGS enabled and GDM disabled

Got the AGESA 1006 updated BIOS the other day (finally!) and now my GSkill TridentZ 2800 is running at the proper speed. POST is quicker as well. I wont bother changing the RAM now 🙂
