VRM modify ICC_MAX to run high TDC OEM cpu

[zheng8526885]

Hello! May I ask if there is a solution for the Sugon I620-G30 with the motherboard model 60P24-US Rev R1.1?

Hi, I have an X11SPM. How do I restore the factory VRM settings?

write ICC_MAX = 228A with Elmor Labs EVC.

Thanks for your reply. I only have the MCP2221a tool; could you please provide a command prompt? Thank you.

there is none because there is a programing-limit.
e.g. with the PXE1610C there are normaly 14 banks left(remaining attempts)

no. check what VRM controller is used (near area around the power stages / chokes/coils(grey blocks) )

please provide a picture of VRM section. there are two versions, one with 5+1(ok) and one 4+1 (too weak) power stages.

DL360Gen10 mod was success, 2x 8259CL run perfectly nice in stress --cpu 96, Geekbench etc! Much love, also Optane PMEM DIMMs work too!

Has anyone done X11DPG-SN yet?

@RolloZ170 do you think it's suitable?

seems not

do you think it's suitable?

5+1 VRM should work. you have to find (undocumented) JVRM, if lack of them solder to a resistor near one VRM controller.

Hey actually quick question; Can I do the programming with supported CPUs or does it need to be done with the unsupported ones.. Sorry if it's obvious, but can't hurt to ask

better with supported CPU, to avoid aut turn off while programming....

Found it.

X11DPG-SN:
At the rear near the BMC (both JVRM1 and JVRM2)
TDA21470 gate drivers

X11DPG-SN:
At the rear near the BMC (both JVRM1 and JVRM2)
TDA21470 power stages

connect same as for X11DPi (page 1)
do a scan to find out the VRM controller vendor and addresses.

I'm getting ready to do the reprogramming modification to the VRM on a x11dph-t, v1.10, just want to get your opinion on the easiest i2c programmer module. It looks like you prefer the mcp2111a. Is this board a good candidate for cpu's such as the 8259cl or the 8275cl, I understand adding heatsink's and good cooling will be required.

microchip MCP2221a (Adafruit etc.) can do most vrm controller devices.

it is ok, the VRM without Heatsink for CPU0 is 6+1 (CPU1 5+1)

This is the correct unit, it's from Amazon..

I want to give my thanks to @RolloZ170.

Was able to mod my X11DPU motherboards that did not already have an unlocked VRM

Also managed to do the VRM modify on my supermicro X11DSC+ board.

Everything like a charm and my servers are now rocking Xeon 8275CL cpu's without a hitch.

I'm getting ready to try a pair of the 8275cl cpu's on a x11dph-t, just ordered the programmer module

yes exact.
