Can not edit posts on this forum??? So here's a few images to go with my last post.

Current ram settings.


SIV utility


Oc'ed to 4200 stable.


I was able to get it to 3600 with 1 stick but not Windows 10 stable.

Last post on this subject. Flashed my MB to the latest bios V1.42 and no go on 3600Mhz with my ram, still at 3200Mhz. I have searched, Googled, for reviews on the Phantom Gaming 4 MB. Nothing. Closest I found is a review for the Phantom Gaming ITX/AX MB in which they used Corsair Dominator Platinum DDR4 3200MHz 2x8GB.

There are reviews out there for the B550 Taichi MB where they have used G.Skill Trident Z Neo 2x8GB DDR4 3600 (F4-3600C16Q-32GTZN).

And on other B550 MBs: https://www.tomshardware.com/best-picks/best-amd-b550-motherboards

So I've come to the conclusion that the reason I can not set my ram's XMP to 3600Mhz is a combination of my cheapo Asrock MB, (paid $80. for it after rebates), the fact that the Ryzen 5 3000 CPUs according to their specs support ram only up to 3200MHz??, but mostly Corsair's Vengeance 3600Mhz ram not being compatible with my MB.

Still obsessing over trying to get my ram to run at its XMP profile of 3600Mhz on my B550 Phantom Gaming 4 MB. I posted the question over on the Reddit/Asrock forum, https://www.reddit.com/r/ASRock/, and got some good advice about changing other voltages and the ProcODT setting. I was able to get my MB to post and set the ram at 3600Mhz, but it was not stable. Things that I tried though may be useful to others with B550 MBs and 3600Mhz ram.

Used HWiNFO64 and AMD Ryzen Master for readouts.

1. I flashed the MB to bios 1.20. Left everything at default and set the ram to its XMP values, 3600Mhz, FCLK 1800, 1.35V, and timings to 18,22,22,42,64. It booted but it defaulted back to 2133Mhz. The SoC voltage was 1.200V. Bios higher than 1.20 set the SoC voltage on Auto to 1.087V, higher is better.

2. Increased the ram voltage to 1.38V. It booted and the ram was now at 3600Mhz, SoC voltage 1.200. Unfortunately, this was not OCCT (medium data set) and IntelBurn Test (stress level Very High) stable, and I got a BSOD.

3. Decreased the ram back to 3200Mhz, 1.35V, timings to 16,20,20,38,57. Ram was at 3200Mhz but the SoC had dropped to 1.087V. This was OCCT (medium data set) and IntelBurn Test (stress level Very High) stable.

4. Per Ryzen Master CLDO VDDP and VDDG were 1.0979V, GearDownEn was enabled and ProcODT set to 60.

5. In the bios, set ram back to 3600Mhz, 1.38V, and timings to 18,22,22,42,64, set CLDO VDDP and VDDG to 0.95V, and ProcODT to 48. Booted and ram was at 3600Mhz, SoC at 1.200V, CLDO VDDP at 0.9474V and VDDG at 0.9976V. OCCT (medium data set) started throwing out errors after ~30 seconds, but IntelBurn Test (stress level Very High) completed 10 passes successfully.

6. Last try, set CLDO VDDG to 0.90V and ProcODT to 43.6. VDDG was still at 0.9976V. Same results with OCCT (medium data set), errors after ~30 seconds. Ran OCCT again with large data set, errors after ~2 minutes.

So back to setting my ram to 3200Mhz. My advice again is get 3200Mhz ram that's on your Asrock B550 MB's memory QVL list.

Sup guys, I had this issue as well. I had 2x 16gb 3600mhz Vengeance RGB sticks where it detected at 2133mhz and I was able to bump it up to max 3133mhz. I have found a fix for me after 1 whole day of trying any of my solutions from overclocking and much more tinkering.

The fix is quite simple.

1. I had my 2x DRAM sticks in DRAM slots A1 & B1
2. Relocate the 2x DRAM sticks into slots A2 & B2 as it has more support for faster sticks in the B550 Phantom Gaming 4 Mobo unlike A1 & B1.
3. Get into Bios and put on the XMP profile & bump it up to the speed it's manufactured for (3600mhz for mine)

*If you get 2 red lights on your GPU & DRAM mobo leds after putting it in the new slots, it just means you haven't actually pushed the DRAM all the way in. I pushed it a little more and heard new clicks and it got fixed.
