MI100 memory Operating points

[uvos]

sorry if this is an inappropriate place for this question. I have a couple of MI100s in a server, but they idle terribly, it would appear that they have no lower vram operating power level than full speed, see:

# cat /sys/class/drm/card2/device/pp_dpm_mclk 
0: 1200Mhz *

I was wondering if you guys have access to a newer vbios that potentially includes more power levels as idle consumption like this is fairly unreasonable. Below for reference amdvbflash output:

adapter seg  bn dn dID       asic           flash      romsize test    bios p/n   
======= ==== == == ==== =============== ============== ======= ==== ================
  0    0000 03 00 738C MI100(Slave)    GD25Q80C        100000 pass 113-D3431401-100

Thank you very much for any help you can provide and i apologize for the intrusion.

Hi @IMbackK, can you please reach out to your HW vendor for the newer VBIOS? Thanks.

Hi @nartmada unfortunately we cobbled this machine together from parts so there is'ent really a vendor point of contact for it.

I am sorry @IMbackK. We cannot distribute the VBIOS arbitrarily, and VBIOS update must go thru the HW vendor.
