    Hi Shawn,
    Is there perhaps an update for this Tutorial? I have a query about my laptop memory (see my profile for system details) that I want to update to 32 GB (Dual Channel, I have 2 slots, 1 is empty) and use CPU-Z to find out the actual speed I run my present SK Hynix (HMA851S6CJR6N - VK Non ECC PC4-2666V 4GB DDR4) at. Is that very low DRAM frequency I am seeing on the CPU-Z memory tab the actual speed that my Intel Comet Lake mbo runs the Hynix at? and (same tab) there is another "NB frequency" (North Bridge?) with twice the speed of DRAM when on the power adapter but shows the same speed on battery (600-1100 MHz only) it fluctuates, average is 600 MHz on battery probably my "balanced" power setting is throttling the CPU. The tab SPD on CPU-Z is supposed to give details but both slots are greyed out (blank), either Windows10-1909 is blocking this info or Hynix?? I have CPU-Z version 1.92.0 for x64 and validated it.
    The info from Wmic, Task Mngr and Windows all state the Hynix speed as labeled but not the actual speed the module is running at and my latest UEFI Firmware only reports the size of the memory (no advanced info on memory) so I guess I have to use CPU-Z to find out more?
    There is no helpful info on the web incl. CPUiD on this topic
    Thanks

    Hello @FrankW,

    The full details command in option 2 is about as detailed as Windows will report for the RAM module.

    You could check your BIOS settings to see what it reports about the RAM.

    Since the RAM is soldered in one slot, about all you can do is add another module of the exact same type and size.

    wmic MemoryChip get BankLabel, Capacity, MemoryType, Speed, Tag

    On PowerShell, the above does not work, while the following works.

    wmic MemoryChip get BankLabel,Capacity,MemoryType,Speed,Tag

    See the output below:
    Code:
    PS C:\Users\Matthew_Wai> wmic MemoryChip get BankLabel, Capacity, MemoryType, Speed, Tag
    Invalid GET Expression.
    PS C:\Users\Matthew_Wai> wmic MemoryChip get BankLabel,Capacity,MemoryType,Speed,Tag
    BankLabel  Capacity    MemoryType  Speed  Tag
    BANK 0     2147483648  24          1333   Physical Memory 0
    BANK 2     4294967296  24          1333   Physical Memory 2

    I also thought first it was soldered but Acer Support told me this about my model:Determine System Memory Size, Speed, and Type in Windows 10-memory.png
    I haven't opened my laptop to check this but assume Acer is correct.
    I am after the actual working speed not what the DDR4 module can handle and that is what Windows is reporting.

    In Powershell, using Win32_PhysicalMemory class:

    Code:
    Get-CimInstance -ClassName Win32_PhysicalMemory | Format-Table Capacity, Manufacturer, FormFactor, Banklabel, Configuredclockspeed, Speed, Devicelocator, Serialnumber -AutoSize

    where FormFactor:

    (0) Unknown
    (1) Other
    (2) SIP
    (3) DIP
    (4) ZIP
    (5) SOJ
    (6) Proprietary
    (7) SIMM
    (8) DIMM
    (9) TSOP
    (10) PGA
    (11) RIMM
    (12) SODIMM
    (13) SRIMM
    (14) SMD
    (15) SSMP
    (16) QFP
    (17) TQFP
    (18) SOIC
    (19) LCC
    (20) PLCC
    (21) BGA
    (22) FPBGA
    (23) LGA

    Thanks Dimitri
    Configuredclockspeed = Speed exactly the same value as on the Hynix label (2667 MHz), CPU-Z is indicating 1/3rd of that as DRAM frequency around 600 MHz while the Northbridge mbo controller indicates 4400 MHz when I am on power adapter on battery also 600 MHZ depending on my Power Saver settings. I hope by putting in two identical 16GB 2666 MHz DDR4 modules in slots 1+2 my DRAM bandwidth will increase to the Northbridge frequency of 4400/2=2200 MHz when on power adapter?

    On PowerShell, Get-WmiObject can also be used as shown below:

    Code:
    (Get-WmiObject Win32_PhysicalMemory | Format-Table Capacity, Manufacturer, FormFactor, Banklabel, Configuredclockspeed, Speed, Devicelocator, Serialnumber -AutoSize)

    I found out from Acer's community forum that the memory configuration I got for my model is an "old" one and that Acer changed it in March toDetermine System Memory Size, Speed, and Type in Windows 10-new-table.png
    and in the laptop spec. it is also stated
    Determine System Memory Size, Speed, and Type in Windows 10-latest-slots.png
    So I had it completely wrong, the reason CPU-Z does not detect SPD (blank slots) on my laptop has nothing to do with EEPROM but the fact that the 4GB Hynix is soldered and my only 1 slot is empty.
    I already ordered two identical Kingston 16 GB DDR4s and I am trying now to change that to 1x16 GB Hynix with identical speed to the one onboard to facilitate Dual Channel, 2x4 GB would probably be better but I find 8 GB a bit low for a x64 system. Still have not opened up my laptop but others have (same model) and found only one slot.

    I found out I have indeed only one slot free and ordered an identical 4GB Hynix DDR4 for that slot to go Dual Channel.
    Question: It looks like my present DDR4 (soldered) 4GB Hynix is being throttled by Windows even on maximum perf. with my power adapter connected. Dram in CPU-Z never shows longer than a second the correct 1300 MHz (always on 660 MHz) and Winsat mem reports 13GB/s maximum (should be 20+ GB/s) as my DDR4 is 2666 MHz, CL19, PC4. Also WINSAT Formal reports bad memory for x64 but that could be the 4 GB. Any idea what is causing the throttling, is 660 MHz (single) an acceptable speed for my system with Intel i7 Kaby Lake and Comet Lake mbo (my bus speed is 100 MHz)? There is no option in my UEFI for memory.

    Determine System Memory Size, Speed, and Type in Windows 10-good-cpu-z.png

    It's OK now I get the correct DRAM frequency for my single DDR4, I went online (news) and had a fast WIFI link for a change and that triggered the CAS (19) and DRAM. WINSAT mem still reports below or around 10 GB/s but that is probably not related to DRAM and includes all the background apps running?

    A note: I just fired up an older [HP Pavilion DV6] Notebook and took screen shots showing that it uses a 4GB RAM module and a 2GB RAM module for a total of 6GB Dual-channel, shows the modules must be matched except for the capacities. I have a couple of Desktops with the same "mismatch" that also work just fine.

    The setting in the BIOS on all of them had to be changed from Single Channel for Windows to properly see it.
