XMP issue on ROG Strix Z790-E Gaming

[BRM]

In December 2022 I decided to replace the components in my PC.

Very satisfied by ASUS for many years, I chose a:
- Rog Strix Z790 E-Gaming,
- Intel I7 13700K,
- 2 Corsair 2*16GB DDR5 Vengeance Pro RGB kits,
- M2 WD SN850X,

On receipt of the kit, I installed the components in my case and updated the BIOS to version 0703.
I activated an XMP profile in the bios without any problem and installed my applications. So far this week, I haven't encountered any stability problems with my configuration.

Two weeks ago, I made a configuration for a friend:
- the same motherboard: Rog Strix Z790 E-Gaming (working on my PC since december like a charm),
- Intel I9 13900K,
- 2 Corsair 2*16GB DDR5 Vengeance Pro RGB kits,
- 2 M2 Samsung 990 Pro,
- Asus Rog Strix Geforce RTX 4090 OC,
- Asus Thor 1200W power supply,
- Asus Rog Strix Helios case,

After installation, I configured the BIOS and activated the XMP profile.
During installation of the operating system I encountered a large number of BSODs and instability.

I decided to check my settings to see if there was a configuration problem. Finding nothing, I decided to update my BIOS to version 1202, along with all the necessary drivers.
From that moment on, my PC started to give me numerous BSODs and application freezes.

Finally, I have been forced to disable XMP for both PC's in order to keep the PC's running!

It is therefore clear that the problem lies with the BIOS and not with the components, because my PC with version 0703 has been running smoothly for over 7 months with two DDR5 memory kits with XMP enabled!

I hope Asus will solve this problem, because we're talking about gaming devices, not entry-level products.

Hello BRM,

You're having stability issues because you're combining two memory kits.  Plus, four sticks puts more strain on the memory controller.

The easiest thing to try is raising a few voltages to see if it becomes stable.

On the AI Tweaker tab, try these voltages:

VDD voltage - 1.40v

VDDQ voltage - 1.40v

CPU System Agent voltage - 1.25v

At the bottom, Advanced Memory voltages:

IVR Transmitter VDDQ - 1.40v

Memory Controller voltage - 1.30v

If raising these voltages doesn't help, setting your ram manually instead of using X.M.P. may give better results. 

Combining memory kits is not a good idea, purchasing a single 32GB memory kit is the way to go.

Does raising those voltages get you stable?

Hello Nate152,

I have the same issue but my setup is slightly different and i ask myself if I can use the same config that you post to keep it running.

I use the Motherboard “ASUS ROG STRIX Z690-F” and the memory “Kingston FURY DIMM 64 GB DDR5 5600 36-38-38 (4 x 16 GB)”.

Can I use the voltages ore are they to high for my Mobo and Ram?

Thanks, but I'll try manual settings as soon as I have time.

As for the rest, before buying equipment I download the manuals and read them to note the important elements that could have an impact on my choice.
And there is no indication (E20593_ROG_STRIX_Z790-E_GAMING_WIFI_UM_WEB.pdf - page 1-6) that it is preferable to use only 2 memory modules on the motherboard, on the contrary there is a recommendation to ensure that all the modules are of the same type to guarantee correct operation.
Maybe my English isn't good enough, but I'll repeat that before updating the bios my PC ran without BSOD for over 7 months without any problems.
It's not acceptable to have a motherboard with 4 memory slots if you can't put memory on it, it's a joke!
Overall PC performance is not the same with XMP enabled and without it.

Hi 0rig_Ignacio

I also have the ROG Strix Z690-F Gaming WiFi, I'm using 16GB (2x8GB) Kingston Fury Beast 6000MT/s 40-40-40-80-2T. 

The voltages I listed are fine, I've seen some users push VDD and VDDQ up to 1.50v - 1.60v.

You can take VDD and VDDQ voltage up to 1.425v, to go higher you'll have to enable High Dram voltage mode.

Thanks for the fast reply. Unfortunately the setting doesn’t working out for me. Maybe it’s because I use four memory modules. I tried it with “XMP1”, “XMP2”, “Manual”, “Auto”.
