You won't find such an option in proprietary systems like this one, which value stability over functionality/performance.

Thanks, at least this is sorted. turbostat lists that too: cpu0: MSR_RAPL_POWER_UNIT: 0x000a0e03 (0.125000 Watts, 0.000061 Joules, 0.000977 sec.) cpu0: MSR_PKG_POWER_INFO: 0x000003e8 (125 W TDP, RAPL 0 - 0 W, 0.000000 sec.) cpu0: MSR_PKG_POWER_LIMIT: 0x4285a800e383e8 (UNlocked) cpu0: PKG...

I asked a while ago whether anyone tried to repurpose an HP Z2 G9 Tower/Lenovo ThinkStation P3 W680 Tower/Dell Precision 3660 W680-based workstation motherboard and got no response, so I decided to go ahead and do it myself. I managed to buy a second-hand HP Z2 G9 W680 motherboard for less than...

For the record, shorting pins 3 and 5 works to cheat the G9 to think a 125W fan is installed, but only on a 12th gen. I am using an aftermarket fan and this worked so far. It’s also possible to short 3, 4 and 5 to make it shut up about the CPU fan in case it is completely absent. After...

Do you happen to have source for that? I just tried to upgrade from 12th to 13th and the system turns off immediately. I have a Z2 G9 tower and the early revision board, wondering if I am affected by those issues you mention.

Replying to myself, but indeed there is an update: support for EDAC in Alder Lake-N, Raptor Lake-P, Meteor Lake-{P,PS} was added in kernel 6.8: https://lore.kernel.org/lkml/20240106121912.GAZZlFQJdtoGzRxIiE@fat_crate.local/ EDIT: actually, no, this was for igen6 module, which provides In-Band...

FYI, support for EDAC in Alder Lake-N, Raptor Lake-P, Meteor Lake-{P,PS} was added in kernel 6.8: https://lore.kernel.org/lkml/20240106121912.GAZZlFQJdtoGzRxIiE@fat_crate.local/ EDIT: actually, no, this was for igen6 module, which provides In-Band ECC, not a full-blown ECC with dedicated memory.

Is there any update in that matter?

Maybe should have been a bit more elaborate explaining my use case. My 4 LX consumes a whooping 14W with a single DAC connected, despite ASPM and all power saving enabled. My idea is to get rid of 4 LX altogether and switch to Ethernet. 2 ports on the NIC, 2 x 1Gbps. One of those would be for...

Replying to myself, but it seems it is not possible: https://community.intel.com/t5/Ethernet-Products/I350-Controller-bridging-ports-together/m-p/1393520?profile.language=de https://stackoverflow.com/a/63449425/665932

Ah, in such cases I used an extension cord and an additional device of a fixed power draw, like a bulb, and then subtract the Watt measured.

Thanks. But woah, only 0.1W with DAC attached? Is the network interface actually up, per dmesg/ifconfig/LEDs in the back?

For the info on E-Switch, here's from Mellanox: https://doc.dpdk.org/guides/nics/mlx5.html#multiport-e-switch Basically I want to be able to have my WiFi AP (with VLANs) connected to NIC port 1 talk to a passive switch connected to port 2 and all the SR-IOV virtual functions on either of these...

And how much with a DAC connected, if you have one handy?
