[UNLOCKED] VAIO SVE1712 C5E

[Sebashi]

Hello everybody

After unlocking advanced menu on this SVE1712 laptop, I've seen in advanced tab an extented ICC menu, but all option are greyed out ...
(the setup utility module
  VAIO_SVE_modded_Setup_Utility.rar (Size: 88.6 KB / Downloads: 113) )
That's why I have tried to mod the ME firmware with the help of some topic seen here at techinferno and [url=
http://www.bios-mods.com/forum/Thread-UE...e=120]here on famous XPS15 thread.[/url]

Here is the pinmod done , according to intel datasheet, 7 series chipset have the same bootstraps as 6... the soldering part was really tricky !!
Thanks to Timewalker for sharing Coderush research

took me 1 hour to do it properly





Pinmod removed now

It must be done to enable descriptor setting override and allow flashing a modded descriptor region with that sequence 0000FFFF0000FFFF1801FFFF from offset 60h

Here is how I ended


Screenshot of the modded bios:







Here it's interresting to see the "ICC overclocking lib"



But after modifiying my ME region dump with FITC 8, I'm sticking with something interfering in bios, flashing the modded ME FW don't unlock icc menu in bios and also don't reflect my changes.
Have tried to remove and reinstall Intel xtreme utility withstill no access to any parameters, even BCLK ...

Moded ME Firmware
Original ME firmware

Any idea ? I have checked the PCH straps and ICC profile 0 should be loaded on boot via softstraps .
There is in the bios a setting in extented ICC that is set to "lock only dynamic ICC registers" and could be set also to " Lock all registers"

There is a DXE module called 'ICC overclocking' in Phoenix tool.
what I found interresting, is that "ICC lib"

I'm actually running the modded ME FW with no visible changes, the firmware have been also just updated from 8.1.0.1248 to 8.1.10.1286.

So I read in "ME fw bring up guide" that only specific chipset can have overclocking ICC capabilities.
Here is mi CCTool output

Code:

cctwin.exe gcc
G:\Intel Management Engine\ME (1.5M_8.1.10.1286)\ICC_Tools\CCT>cctwin gcc

Intel (R) Clock Commander Tool Version: 7.1.20.1119

icc_hw_version_number = 0002.0000
icc_hw_sku = BASIC // cannot be changed, depending on chipset (AFAIK)
max_size_of_temporary_uob_record = 56
icc_boot_status_report [0x00000c00]:
boot event: "OemClkRangeMinViolation" // OC mod range register not allowed
boot event: "OemClkRangeMaxViolation" // OC mod range register not allowed


HECI CMD Status = 0x00000000 (SUCCESS)

In order to enable overclocking setting, read the following guide to properly set your ME FW (Thanks to kasar;-))
