[Alder Lake] RAM geometry detected incorrectly

[Technologicat]

Hi,

I have a CLEVO PD70PNN1 laptop with 32GB of DDR5 RAM (2 x 16GB), but CoreFreq reports only a single 16GB DIMM in the DIMM geometry. However, the Total RAM is reported correctly (32GB).

Output of corefreq-cli -s -n -m -n -c 1 -n -k -n -B -n -M below.

If it matters, I'm running Linux Mint 21.

Is there any other information I can provide to help?

Hello,

First CoreFreq report with Alder Lake/H I'm receiving, you have been lucky to get parts of the IMC.
Indeed I will need your PCI Host Bridge or whatever MCH device id to trigger correctly an IMC decoder.

Please post here the full output of lspci -nn

Hello,

Can you pull and try the new changes in the develop branch ?

I will need a refresh of corefreq-cli -s -n -M

Thank you

[cyring]

Btw generation 11th up to Raptor Lake can now experiment the SA voltage monitoring. You have to build this way:

make ARCH_PMC=PCU clean all

In the UI, switch to the Voltage view and check SA

Here's corefreq-cli -s -n -M on the same machine, using 1cd8f35 from the develop branch.

Seems to detect all 32GB correctly now. Thanks!

Seems to detect all 32GB correctly now. Thanks!

It works but not as the way I was expecting it to do!
I was expecting 2 controllers with one DIMM in each.

Bus rate has decreased to 1900 MHz with DDR5 about 2400 MHz. Does it sound good to you ?

Other addition for your platform is TCO which still stay OFF.
Perhaps it is disabled in your BIOS ?
You can however enable TCO from CoreFreq UI: please let me know if that works ?

EDIT: Sorry, I meant to say IBT (indirect branch tracking), not BTI. The kernel option is ibt=off, and having to do this is a known problem with the interaction of the Linux kernel with the nvidia proprietary driver on machines with Alder Lake CPUs.

Original post below.

Yes, the geometry seems weird.

As for the bus rate, I'll need to check what the BIOS reports, and post back later today.

I have to admit I'm not that familiar with processor internals. What is TCO in this context? I didn't find anything useful on the internet due to the overloaded acronym - even Intel themselves only talk about total cost of ownership. I'll look in the BIOS for a TCO setting.

Speaking of processor features, one detail I forgot to mention - I have bti=off ibt=off in the boot options for the kernel, because with BTI IBT enabled (branch target identification, I suppose?) (indirect branch tracking), the system crashes randomly with the current kernel (5.15.0.60-generic), at most within minutes of booting. Probably unrelated, but thought I should mention it just in case.

Also, for what it's worth, this is a new system, and there are still some other random issues I need to debug:

• Random system crashes when playing Cyberpunk 2077 (Linux, Steam, Proton Experimental). Seems to happen only on this one specific game. It may run fine for 20 minutes, then crash the whole laptop. When this happens, I can't ssh in, can't switch VTs, alt-sysrq-REISUB does nothing; the only way to recover is to hold the power button to cut the power. Could be due to the NVIDIA drivers, or interaction between the kernel and the NVIDIA drivers. The CPU and GPU temperatures are OK, and ProtonDB says that for an overwhelming majority of users, this particular game works flawlessly. (And for those users that have had issues, there are no reports of random crashes - the game either crashes immediately, or works flawlessly, depending on Proton version.)
• X fails to come up after a cold boot, requiring a warm reboot. When this happens, XOrg.0.log gets peppered with a seemingly endless loop of modeset and NVIDIA detecting the displays. On a successful boot, the same loop seems to run a couple of times, but then finishes, and X comes up normally. Some kind of race condition? But nomodeset is no longer the solution (tried it, NVIDIA drivers failed to start) so I'll need to read up more on this.
• HDMI output freezes (handshake failure?) when resuming from suspend, but the internal display of the laptop works fine. Can be worked around with soft-powercycling the HDMI output using xrandr, or switching to a text VT and back to X. But oddly, scripting the soft-powercycling of the HDMI output as a system sleep script, it doesn't work most of the time. If I run the same commands manually after resuming, the HDMI output comes back up.
• Internal display backlight driver detecting the wrong device (controls the files in the backlight sysfs directory of the discrete NVIDIA GPU, should control the integrated Intel; does not seem to be configurable). I have a redirect service written in bash that I got off StackExchange, which with minor customizations otherwise works fine, but it won't autostart at boot no matter how I configure it in systemd. Low priority for me, since I can start the service manually, so I haven't spent that much time looking deeper into this one.

These seem unlikely to be CPU-related, so just for information :)

I'll get back to you later today after I've looked at the BIOS settings.

This definition of TCO and datasheet I'm using to program Registers
Some Intel modules iTCO_wdt should already be started in your system.
Without those drivers, CoreFreq can manage them, at first, to get the enablement state.

BIOS reports DRAM frequency as 4800 MHz. (I suppose this is including the "double" in the DDR.)

And after booting Linux again, with nothing changed, the memory bus is now at almost 4 GHz?! corefreq-cli -M:

Definition and datasheet - thank you, very interesting! Summarizing, in this context TCO is a low-level system crash watchdog, and the acronym indeed means total cost of ownership. No wonder it was hard to find. :)

The BIOS on this machine has no settings for TCO - or indeed that many settings at all. It is Insyde H2OBIOS version 1.07.02, with KBC/EC version 1.07.05, and ME FW version 16.0.15.1810.

Here's a list of available BIOS settings, other than TPM setup:

• Main:
  • Offboard NVMe controller configuration. Doesn't seem to have any actual settings, but lists the installed M.2 SSD here.
  • Offboard SATA controller configuration. Similar, no actual settings, would list SATA disks if any were present.
• Advanced:
  • VMD controller: enabled/disabled. For RAID? (disabled)
  • Battery low alarm beep: enabled/disabled. (disabled)
  • Advanced chipset control:
    • Display mode: MSHybrid or Discrete only. Whether to enable both GPUs, or the discrete NVIDIA only. (MSHybrid)
    • FlexiCharger: enabled/disabled. Affects the charging speed of the laptop battery. (disabled)
    • VT-d: enabled/disabled. For virtualization? (enabled)
    • UEFI OS fast boot: enabled/disabled. (disabled)
    • Legacy game compatibility mode: enabled/disabled. Apparently, if using Windows, this repurposes the scroll lock key to park the efficiency cores. (disabled)
    • Battery saver: enabled/disabled. Decreases the screen brightness. (enabled)

I'm not seeing any kernel modules with "TCO" in the name. Here is the full output of lsmod | sort:

Cause of DRAM frequency discrepancy possibly found.

After booting the system, the memory bus is at 4000 MHz. But if I suspend and resume, it drops to 1900 MHz.

Next, to figure out why this happens...

By the way, thanks for developing CoreFreq, which makes this kind of detailed analysis possible! I originally installed CoreFreq to be able to monitor individual core clock rates and temperatures, for performance profile tuning. :)

After booting the system, the memory bus is at 4000 MHz. But if I suspend and resume, it drops to 1900 MHz.

Thanks for your return.
I use the Uncore clock ratio in Bus rate computation of Intel 11th and afterwards generations.
Ratio may fluctuate under certain circumstances.

CoreFreq/intel_reg.h

Line 4544 in 1cd8f35

UCLK_RATIO : 32-24, /* Ring UCLK at 100MHz */

Ok, good to know, thanks.

The weird thing is, once I suspend/resume, the reported bus rate stays around 1900 MHz all the way until the next boot - it doesn't fluctuate. Also, the 4000 MHz after a fresh boot remains stable all the way until I suspend/resume the machine, it doesn't fluctuate either.

It also doesn't matter whether the machine is stressed or not, so if the reading is accurate, whatever is happening, it doesn't seem a dynamic performance scaling issue.

I read about Alder Lake and XMP 3.0, but this BIOS has no settings for that, either, so all I have to go on regarding the memory bus rate is what CoreFreq tells me.

Or what other tools tell me - for comparison, I tried CPU-X, which says "Kingston KF548S38-16, 16384 MB @ 4800 MHz (SODIMM DDR5)" for each of the two RAM slots (this is after a suspend and resume).

I've run some test loads (AI training on GPU using a custom code built on TensorFlow; and an MPI-distributed FEM code on CPU, specifically a custom Navier-Stokes solver built on FEniCS). Performance for both seems normal after suspend/resume, but to be sure, I'll have to re-check with a fresh boot.
