Previously I was posting the question, where I determined my Lenovo G550 laptop's chipset by sudo hwinfo | grep Chipset
command:
E: ID_MODEL_FROM_DATABASE=Mobile 4 Series Chipset Memory Controller Hub
E: ID_MODEL_FROM_DATABASE=Mobile 4 Series Chipset Integrated Graphics Controller
E: ID_MODEL_FROM_DATABASE=Mobile 4 Series Chipset Integrated Graphics Controller
<6>[ 7.253812] pci 0000:00:00.0: Intel GM45 Chipset
Model: "Intel Mobile 4 Series Chipset Integrated Graphics Controller"
Device: pci 0x2a43 "Mobile 4 Series Chipset Integrated Graphics Controller"
Model: "Intel Mobile 4 Series Chipset Memory Controller Hub"
Device: pci 0x2a40 "Mobile 4 Series Chipset Memory Controller Hub"
Model: "Intel Mobile 4 Series Chipset Integrated Graphics Controller"
Device: pci 0x2a42 "Mobile 4 Series Chipset Integrated Graphics Controller"
It said that my chipset is Intel GM45
if I am understanding it correctly.
But yesterday I've downloaded Windows based Live CD with CPU-Z and AIDA and they detected GL40
chipset.
Also, AIDA32 said, that maximum memory I could insert into my slots is 4Gb, but I inserted 8Gb, AIDA32 and CPU-Z show it also and it laptop with 8Gb RAM works now without issues. To check if additional 4Gb is used, I've disabled swap
and opened a lot of browsers' tabs and different applications to achieve 4.7Gb memory load.
Who says the truth - CPU-Z and AIDA32 or hwinfo
? Or, maybe, I misunderstood something and they both show correct information?
