Missing info about Memory Modules on HP EliteBook 845

[panther7]

Tested on G8 (gen8) and G10

G8 - AMD Ryzen 5 PRO 5650U, DDR4
G10 - AMD Ryzen 5 7540U, DDR5

Tested with HWiNFO v7.64 (stable) and v7.65-5250 (beta)

This is most likely due to proprietary switches used by some vendors that lock out access to DIMM SPD. We don't know how to enable access and read DIMM details in such case.

Ok, next questions.

1. Mode: Quad-Channel. Really? In docs say: "Memory Channels: 2" https://www.amd.com/en/product/13211
2. 2 Performance and 4 Efficiency cores. Phoenix 2? Some official documents about these informations? I found only, that "MCU A70F8x" are "Phoenix 2".

 

[Martin]

Each DDR5 DIMM is dual-channel.
This is not Phoenix2 and I cannot comment on unreleased products.

Ok,

look on my screenshot, HWiNFO say "quad channel" and P-cores/E-cores (like "Phoenix 2"). I want only know, that detects is truly.

 

[Martin]

Yes, I was surprised about the hybrid core configuration as well and it should be reported correctly. If you also provide the HWiNFO Debug File I can check in more detail.
2 x DDR5 DIMMs are usually run in Quad-channel mode.

Debug log here...

 

[Martin]

HWiNFO reports correctly, also CPPC confirms it. Core0 and Core4 are Performance, the rest are Efficient cores.

 

[panther7]

Ok, thanks for consultation.

May be closed.

 

[panther7]

Hmmm, I am really don't understand.

HWiNFO say P/E cores for 7540U, but these cores have 7545U.

AMD už vyrábí notebookové hybridní procesory. Mají velká a malá jádra

AMD v těch dnech oficiálně uvedlo mobilní procesory rodiny Phoenix 2. Oproti na jaře představeným Phoenixům nejsou pokročilejší, jak by naznačoval název. Ve většině parametrů jsou totožné, ale budou menší, levnější a úspornější. Používají

Yes, it's strange. But what you see in HWiNFO is what the CPU says/reports.

And some info from AMD?
