X170SMG Black Screen after Sleep

[Bidelloman]

Greetings,

 

The moment when last year I changed my stock x170smg's cpu and gpu from 10600k and rtx 2080s to 10900k and rtx 3080, sleep has been an issue regardless of OS ( tested on various linux distributions, windows 10 ltsc 2019, 2021, windows 11 ltsc) where I have black screen on wake. 

 

I also changed bios and EC, have one with subsystem ID support for the 3080, doesn't matter, sleep fails with black screen.

I changed gpu when the previous one stopped working, problem persists.

Reset CMOS and used stock optimised defaults BIOS settings, no matter, after 1 2 days max sleep issue returns ( occasionally it works, especially during shorter duration sleeps).

 

Full Specs:

X170SMG ( originally from PCSpecialist UK)

CPU: 10900k, delidded with copper IHS

Ram: BL16G32C16S4B.16FE Crucial Ballistix 2x16GB 3200MHZ (XMP), 2667MHZ stock frequency

GPU: 3080 mxm

Storage is comprised of 2 nvme ssds and 1 sata..doubt that this matters much to be honest.

 

Cooling mods, though I do not think this matters much either: taobao fans, stock heatsink, PTM 7950 on both cpu and gpu, utp-8 putty on the rest, rockitcool copper IHS on cpu and LM between CPU and IHS.

 

There are only 2 combinations of ram slots that work ( with or without xmp) and those are RAM1+RAM3 (bottom) or RAM1+RAM4 (1 bottom + 1 under keyboard), both present the same issue. 

 

I have tried everything save trying another cpu or different ram or 1 ram stick alone. (EDIT 1: tried the same crucial ram on another laptop, with linux mint, no sleep issue at all, in any scenario. I also tried a single rank 2x8gb sk hynix set of ram on x170 and sleep failed instantly on linux, but seems to be thus far working on windows 11 ltsc, will test further)

 

If anyone has any suggestion...they'd be more than welcome, thank you

Try installing the latest chipset drivers: https://www.intel.com/content/www/us/en/download/19347/chipset-inf-utility.html

Another suggestion would be integrating the latest microcode for the new 10900k CPU to your BIOS.

If all software/firmware options fail, consider a hardware issue (CPU or mobo).

Chipset drivers like every other driver are new or updated, as I said, issue carries over various OSes.

Bios has been updated and is known to fully work with this machine and cpu gpu combo ( so does in mine to be honest if it weren't for this sleep issue ).

Motherboard also never had an issue with sleep with 2080s and 10600k and various ram models.
