Corefreq: Memory Controller data not available on Intel Core i7-4650U + other Haswell models
Problem
- The Memory Controller window is greyed out in the CLI
- Running
corefreq-cli -Mgives no output - This also affects my Intel NUC with a Haswell CPU (
Intel Core i3-4010U) - Both are both "Mobile" & "Ultra Low TDP" if that matters, vs other Haswells
- Same problem on Fedora 31 and Ubuntu 18.04 HWE stack
- Verbose output from various commands is listed below as hopefully helpful data, separated by horizontal lines
Output from various commands from the i7-4650U
# corefreq-cli -B -k -u -M

BTW: The Intel NUC (i3-4010U) has almost the exact same DRAM controller (if these numbers matter).

- Attached is the IMC test version for Haswell Mobile U/Y with Host Agent
0x0a04and Haswell Mobile M/H with Host Agent0x0c04. Including also BDW Home Agent0x1610
- Plz unload any previous CoreFreq
- Untar, build and load this one
- Supply the output of

- Memory Controller window also working
- But no information about the
DIMM Geometryand more0values than other PCs, but well both PCs can read or not read the same values as I can see - FYI The Intel NUC has 2 different RAM chips (1 x 4 GB + 1 x 8 GB) with different timings but same MHz, so according to UEFI it logically defaults to the slowest one's timings, in case the numbers surprise you
- But definitely seems you're on the right path :+1:

Thanks, could you print for both the SPD data and geometry with
dmidecode -t memory
Here you go.
- Reads everything fine on the NUC, and Chip Sizes and Locator + Banks on both, but some errors on the MacBook (see bullet point above that output)

- Whoops: Some errors below, BUT not for the i3 at least. Can try with a Ubuntu USB stick later, just in case it's Fedora's
sysfsor whatever. Also as you can seedmidecodeversion is newer on Fedora, but that generally should be a good thing so...SELinux == disabledFYI. If not it's just... Half-eaten Apple... I guess...

Invalid entry length (0). DMI table is broken! Stop.
- Don't get why the Core i7, 2c/4t, Turbo 3.3 GHz MacBook has a max of 8 GB RAM (I ordered the top-specced - default was 4 GB - gotta think future use man when cannot be swapped), while the cheaper Core i3 2c/4t No Turbo, max 1.7 GHz NUC has a limit of 16 GB. Must be the motherboard, not the CPU, or maybe lack of space for 4 slots, think they're soldered on but anyway take space (maybe 2 x 8 GB chips at the time were very expensive or barely existed, and Apple already charges a ton for RAM), so they cheaped out and programmed it into NVRAM/SMBIOS or whatever a Mac reports it from.

Since the Apple hides the name of the Manufacturer behind a code and never says in specs, must open of possible and boid warranty, here they are (darn thought I had Samsung ones and not Hynix...).
They don't want you to know, just as some iPhones suddenly had either Samsung or Sony cameras because of demand (before only Samsung), but people noticed. People found ways to take photos of certain shapes to determine, and then a guy managed to read it and published an app that Apple banned, LOL.
EDIT: No manufacturer ID for the 4 GB on the NUC, 1315, is Crucial... Remember now.

For your tests:
This archive will try to decode only the number of Channels and the geometry of DIMMs
And according to the Haswell-ULT datasheet, raise the DMFC (memory frequency) to the upper limit of 2933 MHz

Seems to work! Only tried on the Intel NUC as the MacBook is busy downloading stuff from my file server to watch on the express boat back to Bergen (my apartment), then will be packed, as I'm leaving soon. So you'll get the output from the MacBook later.

BTW: Thanks for introducing me to the dmidecode command. Wasn't aware of it. Nice way to check that say my chips in my workstation are actually running at 3200 MHz (XMP). No other tool, not CoreFreq either, show that (Speed & Currently Running Speed).
Such nice commands which are very unlikely to be included with Windows or macOS (latter probably has it locked down for third party apps too), but installed with the system on any distro it seems, server and desktop.
Also a Google search made me aware there's a decode-dimms command if you install a package, but doesn't work on MacBook/Fedora or NUC/Ubuntu, trying both modules it suggests, but doesn't manage to read anything and says "probably not supported on the running system/HW".

Nice. Luckily pretty good 4G out in the fjords now. At my MacBook now.

Some values dmidecode shows would be pretty cool, but yeah it says it gets its data from sysfs so it's maybe outside the "CPU scope/registers/etc", like where you get the other data from. So more code, more to maintain, bugs, as some paths only exists in sysfs if X driver(s) are loaded (say intel_X vs acpi-X), but they do have standardized names at least (if exists path exists, should be correct value). But say a Memory View instead of a Window with additional Speed, Configured Clock Speed, Min/Max Voltage, Configured Voltage... Then we're talking 1 single tool with low-level monitoring of about everything a CPU/RAM tweaker wanna see.
Anyways,
:+1: :+1:
Very fast job. Hope my data somehow made it possible/easier.
At least dmidecode shows my Ryzen values perfectly fine. IDK if that means it can be fixed in CoreFreq as it reads from the CPU.
Cheers,

Can be the same data timings but not sourced from the same registers.
When the IMC _boots_ it trains DIMM latencies, speed, geometry from SPD, if available. But it has its own internal logic to set a runtime configuration.
That's the all point of _CoreFreq_, giving you the usage, rather than the capability of the Memory settings.
I'm not sure DMI will supply this, but it's nice to have both. Perhaps, in the future, _CoreFreq_ will be able with SPD...
However, the datasheets of all Haswell variants I've gone through didn't reveal some registers. That's why you still read zero values.
Previous AMD processors have a BIOS & Kernel Developer Guide (see BKDG in my CoreFreq wiki) which specify the Memory Controller registers.
Zen architecture BKDG has not been made publicly available. Just a preview can be downloaded. That's a reason, most open source initiatives provide less information than a Ryzen Master or any UEFI BIOS.
ACPI tables may reveal some IMC data...
