Thanks a lot! Your label is totally correct. I was able to boot with dual 8175M after the mod. The addresses are 70 and 72.

cpu in socket and powered on ?
some X11SPW (nutanix) do not need VRM mod. what CPU have you tried ?
Hey Rollo,
Did the scan while server was on stand-by with a 4110 installed. Should i power it on and try again?
I need to use a 8259-cl. I didnt actually tried it thinking I would need to mod it.
if the scan doesn't find anthing you have bad connection. where did you connect it ?
The only connector I could find is JVR1. pin1 = SCL pin2 = SDA pin3 = GND. Did swap 1 & 2 to test as well.
can't do anything from here. check connection.
MCP221a can be bad (happened)
bad cable (not well plugged)
Bad cable was the cause. Did the mod... Please add X11SPW-TF to the list. Thanks for the help
Hi Rollo, is it known what VRM the X11DDW-NT board uses? and any differences between rev 1.11 and 1.2? I saw it listed as compatible with the mod, however both CPU1 and CPU2 do not seem to have a VRM heatsink, will there be any possible issues causing blown VRM? Thanks!
not much diff. same controller, but if you use MCP2221a it doesn't matter which.
it is a server motherboard for 1U/2U chassis with jet-air FANs. the Heasinks would disturb the Airflow,
note the motherboard PCB is also a heatsink, the VRM poer stages are soldered to copper, and the coils/chokes can sink heat.
if you want to use the board in a Desktop case install proper cooling.take care of other components like BMC chip etc, all need at least a little airflow to stay alive.
@RolloZ170 thanks for the details. Since I am using it in a desktop case, will it be better to stick with a X11 DPI with a higher revision no. like 2.01a and install the VRM heatsink for CPU1? will that be sufficient with the updated VRM controller and proper cooling, or should I be looking at other boards? Thanks!
Hi Rollo, I found that X11DPG-QT is even better for tower case use with 2 VRM heatsinks pre-installed. How do I check the VRM chip installed for say rev 1.10a vs rev 1.02 of that board? are there VRM chips that are improved and less likely to be problematic? Thanks!
