Hello,
I hope you’re doing well.
I recently purchased the ROG STRIX B850-I Gaming WiFi motherboard and I had Team Group DDR5 T-Create Expert 32GB (2x16GB) 6000MHz CL30 RAM (CTCED532G6000HC30DC01). I’m using a Ryzen 9600X CPU.
It seems that the Motherboard with this RAM is unstable. I can’t pass TM5 / AIDA64 tests using the EXPO profile. Worse, Windows 11 periodically restarts with a blue screen, even when using all default (auto) settings for RAM (4800 CL40).
I’ve tried both the old BIOS and the latest beta BIOS, hoping for improvement, but the PC is still unstable. I also tested each RAM stick separately, but both are unstable on this ASUS motherboard.
I tried to change PSU - doesn't help.
Could you please help me with this issue? I’d really prefer not to change the motherboard or the memory.
I can send you any error logs or perform any tests that might help your team diagnose the problem. Maybe I can report issue to your tech team regarding beta bios?
I have the video but cannot attach it to this message.
Hi! Thanks for your reply!
Here’s what I tried:
2. I took a photo of the CPU and socket contacts. They look pretty good to me.
3. I had been using a third-party contact frame. I removed it and reinstalled the stock mounting mechanism.
4. Everything seems okay so far. I reinstalled everything.
After that, I ran a test with the EXPO I profile with both stick, and it failed quickly. I’ll now test each RAM module separately in the slot closest to the CPU. It will take some time…
Hello @kokox
May I ask if you're using EXPO I or EXPO II and whether you've adjusted any other overclocking settings?
If you try installing a single memory module in the DIMM_A slot, then clear CMOS and enable EXPO again, does the system run stably?
Regarding memory compatibility, based on the memory QVL for the ROG STRIX B850-I GAMING WIFI, when filtering for AMD 9000 series, Team Group, 2x16GB, and 6000 MHz, there are around 27 results. However, the model "CTCED532G6000HC30DC01" is not listed.
If possible, we recommend testing with memory listed on the QVL to ensure compatibility and stability.
Please also refer to Memory Kits - Overclocking and What You May Not Know if needed.
Thank you.
Hi @Jiaszzz_ROG ! Thanks for you reaching me out.
It’s my fault that this RAM is not on the QVL list. I read good reviews about this RAM and the sweet spot for AM5 (this is my first AM5 build), and I didn’t expect such problems. Unfortunately, I don’t have any other RAM to run the test.
I had a theory that the problem is in temperatures. I added extra cooler ontop of the RAM, installed both sticks and it pass overnight TM5 test with this BIOS settings: EXPO I disabled Fast Boot, PPT limit 65W, enabled Turbo mode for the CPU fan, and enabled HD in the BIOS.
Then I removed fan and it continue to be stable for an hour. Afterwards I rebooted the system, add cooler back and TM5 show errors in first 15 mins. It make me crazy!
I follow your suggestion and clear cmos (poweroff the system, press clear cmos for 10 sec, boot) and enable only EXPO I in bios. I also install only one stick in slot A.
I also found that there is a new BIOS version. I’ll install it and test the sticks independently, as you guys suggested.
/ / BTW the failure is extremely unstable. I have thought that one exact stick has problems. But now TM5 works with no errors for 8 hours with this stick after resertting CMOS... If I hadn’t recorded a video where the system crashed with stock RAM settings with single stick in slot A, I would’ve thought I was imagining it.
Hello again! I'm back.
Thank you @Jiaszzz_ROG and @Silent_Scone for your advice.
I reinstall the RAM modules in different slots and reset the CMOS before each iteration.
All BIOS settings are at stock values, except for the specific rows where I add a comment in the logs.
Based on my testing, I concluded that I might have made some mistakes with the BIOS settings earlier, so I tried to be as precise as possible this time. Here's what I found:
- Both sticks appear to work fine separately and together with default BIOS settings or only with minor changes like adjusting PTT (I’m using a small form factor case and a compact cooler).
- Both sticks produce errors when using the EXPO I profile, whether tested individually or together. Stick 2 seems slightly more stable than stick 1, but eventually, both produce errors.
I have a few questions:
1. What can I do with these sticks at this point? I'm not experienced with overclocking — just learning by Googling and experimenting with speed and timing settings. I read that adjusting RTT NOM RD/WR might help. What should I try first?
2. Is there any chance ASUS might add these sticks to the QVL list for this motherboard? 🙂
3. I noticed a strange BCLK fluctuation — please see the attached screenshot. In BIOS, it's fixed at 100, but in HWInfo (version 1.58.0. Drivers installed using ASUS Armory) it randomly fluctuates between 82–108 in some cases. Could this be a root problem?
4. I’m experimenting with EXPO I at 5800, which looks stable after a couple of runs. Does that mean anything? If it’s stable at that speed, should I leave FCLK at 1933 or change it to 2000?
