Rog Strix Z790-H Gaming Wifi bios 2801 (CPU Cor i5 14500) frequent BSOD after wake up from standby

[oneofnine]

As in subjet, I'm facing frequent BSOD (with variable stop code bat alway involving ntoskernel.exe) after wake up from standby and even after or before user log in with Windows 11 pro 24H2. No BSOD during normal use, also heavy with video games. The frequency of this anomaly has increased since I updated the bios to ver. 2801, until then I had used a much older version (2201) but more stable. I always used RAM configuration with XMP enabled, I launched at least 3 times the complete RAM test from the BIOS without any error. Even using Linux I've never faced a such erratic behaviour.

However, the only way to reduce or eliminate these BSOD appears to be disabling XMP and letting ram to run at 4800 Mhz. I've a Corsair 32 Gb Memory kit chosen from Qualified Vendor List tested to run at 6000Mhz, is there a way to make runnig memory at XMP speed without this issue?

If the ram stable with default 4800Mhz then is sound like weak memory controller.

Try increasing Ram/MC core voltage.

Could you suggest me how much increases voltage ?

Hi @oneofnine 

What's the stop code? Have you checked Windows Event Logs?

[oneofnine]

These are last 5 BSOD recorded

[oneofnine]

Value like these can help?

1) Dram VDD voltage - 1.40v

2) Dram VDDQ voltage - 1.40v

3) CPU System Agent voltage - 1.28v

At the bottom, click Advanced Memory Voltages

4) IVR Transmitter VDDQ voltage - 1.40v

5) Memory Controller voltage 1.38v

although it seems strange to me that the xmp profile does not set the RAM voltages correctly, I applied the above values (thanks to Nate152) and no more BSODs have occurred until now.
