Z790 Maximus Extreme + 7200MT/s DDR5 Instability

Selder
Level 7
I am experiencing stability issues when using the F5-7200J3445G16GX2-TZ5RK sticks on an Asus Z790 Maximus Extreme when running the DIMMs on their XMP I or II profile. These instabilities can be any of the following:

- random PC reboots when idle or stressed
- WHEA event code 17 in Windows event viewer
- PCIe device and/or PCIe bus errors

When running the F5-7200J3445G16GX2-TZ5RK sticks without the XMP I or II profile, the rig boots but obviously at default clockspeeds for the RAM.

Here are the specifications of my rig (except for the 2nd kit of DIMMs, currently running only 2 DIMMs in slot A2 and B2) : https://pcpartpicker.com/list/MjQJW4 . BIOS and MEI have been updated to their latest version. Windows 11 22H2 with a fresh (yesterday) Media Creation, standard installation no GPO's or anything. Running without Antivirus, and Memory Isolation is disabled (required for Intel XTU Tool).

I am currently running the same rig with the F5-6000J4040F16G (slower and looser timings) and that's perfectly stable (I can torture the rig with Techpowerup's Memtest64 without error) and run any benchmark and get consistant results. Performance is awesome 🙂

I'm wondering if anyone has an idea what the issue could be. As far as I'm concerned, this should all work "nearly out of the box" (aka: set XMP and done) and I shouldn't have to fiddle around with the gazillion memory tweaking options, should I? 🙂

We could spend a whole day making comparison after comparison, but all these comparisons will ignore the simple fact that an end-user should expect the products he buys to meet the manufacturer's expectations, right? You simply cannot have it both ways: praising your product to the sky and luring customers with "O.C." (even with "+" symbols) and then saying afterwards "oh ehhm well, ehh, it doesn't work like that" 😀Â*

This obviously doesn't go for Asus only: G.Skill, Intel, ... they all do the same.

And of course nothing is guaranteed, but that all the components I chose do now all work well together as advertised, that is the most important thing and that is what I was talking about. I didn't expect anything else, Asus always delivers 😛


Will meet manufacturers expectations - when the new bios is completed. The honest truth. lol

Asus has to launch the boards according to Intel's chipset and CPU schedule, and sometimes there's a bit of time needed before bios meets advertised specs.

Love my ROG board! 😮

Clearing all cookies should resolve it, have replicated here.

Or ... just wait until Asus fixed these kind of things in their bios 🙂

Beta 0810 fixed all issues for me.


Glad that did it! It seemed like you were running out of patience so I guess the timing was spot on. 🙂
A bus station is where a bus stops. A train station is where a train stops. On my desk, I have a work station…

Yes, thank you very much. No success the first time, but I just tried clearing everything again and it worked this time. All good 🙂

Beta 0810 is great! Again, solved everything, rig is rock-solid with 7200MT/s, love it 😀Â*

Mine G.skill 7200 CL34 is stable @7200. I was able to get it to 7400CL34. Mem86 pass. However, when running CInebench R23 10Min. Within 8 min system crashed. try twice already. I gave up and change it back to 7200.

Try active airflow. Having the PMIC onboard the modules means this can be even more beneficial than DDR4.

Maximus Z790 Hero with 13900KS here and bought the G.Skill F5-7800J3646H16GX2-TZ5RK.

I installed the latest Mobo bios last week since my PC had random reboots. So I installed Version 0904 bios. I have set the XMP I or II. In both cases the PC is hanging, rebooting, showing errors on all the tests. TM5, OCCT, u name it....and crashes while gaming! I have thrown on it a huge Noctua Industral Fan to lower the temps and it still crashes continuously!

While I used the XMPII I lowered the speed of the RAM to 7000hz (while I have paid 7800 kit, 2 sticks only of course) and it runs without problems. It seems that I have to get an Apex and not a Hero board from what I am reading in here. Bought it from Amazon ... doubt they will get it back now...what a pity.

Any chance they will perfect the BIOS in Asus in the future to run the sticks at 7800 or I have no chance and to be looking to sell my Hero? Any solution on this with timings etc....?

Thanks a lot guys...😎🙏
