How to tell memory bus speed on 15600 appliance

Hey guys,

Tried searching this everywhere, but unable to find the info. Data sheet for 15600 does not actually indicate this info and Im not aware of any command to find it.

What Im referring to is something like below you can run on windows

wmic memorychip get speed
Speed
2400
2400

Thanks in advance!

Andy

CPAC-RAM32GB-15600 ===> 8x8GB DDR4 ECC and I guess 2400Mhz but the bus speed is really an unknown stuff, at least for now 🙂

would be lovely to know indeed!

[Expert@SomeFirewall:0 ACTIVE]# clish -c "show asset all" | egrep "^Model" Model: Check Point 15600 [Expert@ SomeFirewall:0 ACTIVE]# dmidecode -t 17 # dmidecode 3.0 Getting SMBIOS data from sysfs.

Note that DMI information can lie about details like RAM speed and even type. This is fundamentally the same data source Windows pulls from, though. The 15600 has two memory controllers (one per socket) with four channels per controller (A-D) and two slots per channel (0 and 1) for a total of 16 slots (1-16). The one I just checked has an 8 GB DIMM in slots 0B0, 0D0, 1A0, and 1B0. Note that this doesn't give optimal bank interleaving, so performance is lower than it could be.
