AMD EXPO Memory issue Suddenly After 7months usage

[evernessince]

@evernessince I mean it worth a try to replace it. The cost is about $1. I'm confident it is not though. I'll even pay for the battery if that ends up being the problem. Win Win for the op.

Agreed, it'd probably be one of the last things I'd try if all else fails as it's unlikely.

G-Skill and AM4/AM5, never ending story after BIOS update. Similar issues many times with AM4/AM5. Always resolved only with BIOS rollback to previous version (usually also with older AGESA).

G-Skill Trident Z5 Neo 32GB 6000Mhz CL32 Kit

I thought only Samsung based kits have this restart issue on AM5 platform.
Could you share your cpu-z SPD screen? I want to make sure it is Hynix indeed.

Apologies for the gigantic picture, not sure why it's doing that.

Now I can get it running normally at that speed once activated in the BIOS & it works fine in windows but my main issue is not being able to restart my PC

I had issue with a G.Skill Samsung based kit, just like that you described. The only solution I found is to buy another Kingston kit.
Now, I am little bit confused, as I said, I thought Hynix based kits should be free of issue.
If possible, try another kit. Or try only one stick.

@jxdking can't say I've heard of this issue unless it was a bad set of memory to begin with. Though with technology anything is possible and I've come across some weird things over the years of playing with components.

Speaking of which @Lionheart where are you at as to resolving? Any progress or troubleshooting steps taken yet?

I went through 2 of F5-5600J3636C16GX2-FX5 kit. One was from Microcenter, one was from G.Skill RMA center directly. None of them worked properly. They tended to get stuck at reboot with EXPO. Changing to different motherboard and different brand did not help, either. I ended up bought Kingston (Hynix based kit) instead, which worked flawlessly.
That is how I get this "Samsung" impression. Also, from what I can see online, G.Skill is not alone. Corsair Samsung based DDR5 tends to have this issue as well.

I just wanted to chime in here and echo the issues OP is having in regards to EXPO and being able to POST properly. I just moved to AM5 a couple days ago, so I haven't had time to update my system specs. Here's the CPU+MOBO+RAM I'm running now:

CPU: Ryzen 7 7700X
MOBO: ASUS X670E Crosshair Hero (updated BIOS to ver. 1415)
RAM: G.SKILL Trident Z5 RGB Neo 2x16GB 6000Mhz (cl 36-36-36-96 and confirmed Samsung)

With default memory timings loaded, PC boots into Windows just fine. But when EXPO I, II or EXPO Tweaked is applied via BIOS, I get a message saying that the BIOS has booted into Safe Mode due to "system instability" and I'm forced to go back into BIOS and disable EXPO. Then everything boots fine again.

Might be some Truth to ASUS and G.SKILL Samsung kits having issues. I saw one of the patch notes said G.SKILL compatibility resolved. I have a sneeky feeling the tFAW is auto set to low. Try like 36 with EXPO profile using EXPO II. This was a issue for me when Ryzen first came out. Some kits just didn't work for me at first and I narrowed it down to the sub-timings set by the motherboard.

The only thing you can do is raise the VDDIO_Mem voltage to 1.2V and see if that fixes it.

Thank you, I'll try that and see what happens.

It won't hurt to try. Hopefully either or both of those fixes the issue for you.

Why didn't I see this thread earlier? Oh well. Has the issue been sorted out?

The first thing I'd check is the SoC voltage. It shouldn't be too low, but it shouldn't exceed 1.3 V, either. With 6000 MHz RAM, around 1.2 V is fine.

If that doesn't help, check the DRAM voltage. It's possible that your particular board has too much Vdroop with auto LLC for your particular RAM. If it sits comfortably at factory defaults, try raising it by 0.05 V.

CPU is probably on its way out

You base that on what exactly?

 

[Gmr_Chick]

Well, I tried both and ended up having to clear CMOS twice due to hanging on the ROG splash screen. Just to double check, could you post screenshots of what exactly I need to tweak? I probably should've asked this BEFORE mucking about in the BIOS

Not sure if this is useful for OP, but I'm using AM5 with G.Skill Trident Z5 RGB at stock XMP profile and here are the voltages
