Z790 Maximus Extreme + 7200MT/s DDR5 Instability

[Selder]

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? 🙂

Just checked the QVL and those kits are still list for my MZ790E. 7800 as well. I’m currently running the 7600 kit with SAV decreased to 1.15V and seems stable here. **

Sorry for the misunderstanding, I was speaking of the Gskill website QVL for the 7600 kit, I should have been more specific.

https://www.gskill.com/qvl/165/374/1665644764/F5-7600J3646G16GX2-TZ5RK-QVL

There was once all 3 Z790 Maximus boards listed as well as both ROG Strix E and F, a total of 5 boards.

Now, only the Z790 Apex is listed, 4motherboards removed from the Gskill 7600 QVL - that's what I meant was a bit weird.

Also, just to be nosey, have you tried 7800?

My SA is 1.313v, didn't see any reason to decrease that value, thermals are all good, it was selected by the 7600 mem kit XMP 1 for Apex, not a value I chose myself.

I cannot move to 8200 at all no matter how loose the timings or addition of voltages, my 13600K i5 CPU is very bad, with an MC SP of 35 - YIKES, I know it's beyond awful.

Grabbing a replacement 13900KS very soon (which was planned months ago), so not going to keep trying to refine profiles with my crummy i5. ho hum, win some lose some, and I lost the CPU silicon lottery. 🙂

The kit I'm trying to run is F5-7200J3445G16GX2-TZ5RK and the Z790 Maximus Extreme is still listed on G.Skill' QVL list.
(this kit is also listed in Asus' QVL list)

F5-7200J3445G16GX2-TZ5RK without XMP (1/2) runs fine, stable benchmarks, no errors in Memtest86
F5-7200J3445G16GX2-TZ5RK with XMP (1/2) everything else in BIOS default, no AI overclock or nothing: hundreds of errors in Memtest86
F5-7200J3445G16GX2-TZ5RK with XMP 2 and Memory controller dram frequency Ratio from auto to 1:2: only a few errors in Memtest86
F5-6000J4040F16GX2-TZ5RK with or without XMP and everything else default, with overclock or without: stable as a rock, not a single error

If the board is defective, I don't see how lower speed and looser timings memory don't give a single error.
Only the 7200MT/s kit at its advertised speeds and timings is not stable at all.

I appreciate the tips in this thread, and where possible I'm trying to give those new settings a go in the next few days.
I also still think that with a motherboard and a memory kit on both "qualified vendor list" Â*I shouldn't be doing all this. Â*Set XMP and be done with it.Â*

I saw a beta bios (0803) in another thread - should I give that a go? Who has more information about that new beta bios? Â*

[Selder]

I have uploaded some of the Memtest86 photos I took yesterday, you can clearly see that the 6000 tests just fine, the 7200 has lots of errors with the memcontroller:dram freq ratio to auto, and only a few errors when setting that ratio to 1:2. Â*That is extremely strange 😀Â*

Yes, your M15E is still on the Gskill 7200 kit QVL list and you shouldn't have to be doing all this.

Bios 0805 is available for the M15Extreme on this page:

https://rog.asus.com/forum/showthread.php?131027-RaptorLake-Resources

Super simple OC - if you want to give it a try - from freshly installed bios and CPU Fan Monitor set to ignore (of course lol)

-Load XMP l
-Disable Adaptive Boost Technology
-Disable MultiCore Enhancement - enforce all limits

[no settings for the CPU, leave it alone for now]

Save out of bios, let the memory train might take 60sec 90sec and boot into windows. Check mem values and thermals and Run TM5 memory stability test

Also, there's a High DRAM Voltage Mode setting way down the Extreme Tweaker page - default setting is disabled - so only 1.435volts is possible for your mem kit.

If you are already XMP l stable - cool, but if not Set High DRAM Voltage Mode to enabled and type in the values 1.4500v for both VDD and VDDQ. Adding small increments of more voltage can help to stabilize. For example: got my VDD and VDDQ running daily at 1.500v, and all is well thermals are good.

Try using TM5 to check memory stability instead of Memtest86 (thumbs up emoticon) 🙂

Download TM5 and unlock with the WinRAR utility available from your M15E ROG support page, it's free...

Hope this helps Mr Selder. 🙂

Thanks a million! I'll try your tips this afternoon when I'm at home!Â*

I seem to have lost the link to a forum with the latest beta bios for the Maximus Extreme damnit. Â*

Oh, OK. Makes sense. I have not tried 7800. It is so stable at 7600 with little improvement I would think going higher. I might try it if my arm gets twisted though. 🙂 Â*

LOL. 😛

Do you Z790 Extreme guys have the High DRAM Voltage Mode setting on your Extreme Tweaker page?

With Apex VDD and VDDQ max out at 1.435v. To override and move higher - you have to ENABLE High DRAM Voltage Mode.

After you enable HDVM, then bios asks you to type in the values you want. I'd go with 1.450v at first.

Mr. Hopper - you might be able to grab 7800 stable 🙂 by adding a bit of VDD and VDDQ. Try using higher volts and copy/paste the XMP settings from the Gskill 7800 kit for first attempt, then if you make it can always tighten down timings later.

https://www.gskill.com/product/165/374/1668740011/F5-7800J3646H16GX2-TZ5RK

------

For example: I was at 7800 36 46 46 121 1.450v stable.

So for 8000 first attempt I just increased VDD/VDDQ to 1.500v and copied the XMP values from the Gskill 8000 kit which are - 8000 38 48 48 128.

Then slowly tightened those timings down to 8000 36 46 46 121. Not certain that makes any sense but I simply used the Gskill 8000 XMP values from their webpage as a "starting point" for primary mem kit training, then tightened timings down later.

https://www.gskill.com/product/165/374/1669019807/F5-8000J3848H16GX2-TZ5RK

So currently I'm at TM5 - no errors:

7600 CL36 46 46 121 1.40v VDD/VDDQ
7800 CL36 46 46 121 1.45v VDD/VDDQ
8000 CL36 46 46 121 1.50v VDD/VDDQ

And long story short, I've got a pretty bad 13600K i5 according to SP values of IMC SP35 and all cores SP67. 😞 So not going to put any more time into mem overclocking until I can replace the 13600K i5 with a 13900KS i9, this week or next week. Then, I'll try again. 🙂

I'd love to try a low latency profile like 7600 CL32 44 44 87 1.5volts, but I'll wait for a new CPU.

Yes. There is a high DRAM voltage setting on the extreme board. I am reluctant to try those settings as it’s not a 2 DIMM board as in the Apex. I think you have a higher tolerance with your board but it’s worth a try. Scone had warned that the 4 DIMM boards may not be as conducive to these high memory OC as the Apex. Â*

That's extremely interesting.

I'm hoping the Z790 Extreme and Z790 Hero DDR5 instability issues some are experiencing is not due to lack of voltage for the mem modules.

My 2sticks run all day at 35C to 37C at 1.500v on a test bench with no active fan - only ambient room cooling, no issues.
