#1 [OFFER] Various Gigabyte Z170-HD3-DDR3 BIOSes with Coffee Lake support by chinobino 05.04.2019 12:48

I have had a couple of requests for my modded BIOS so here it is.

DISCLAIMER; I take no responsibility for any problems associated with the use of this BIOS, you must do the pad mods on the CPU to protect the motherboard CPU socket pins or you will permanently damage your motherboard with a Coffee Lake CPU!



[Edit] The checksum has been corrected so this BIOS can be flashed with Q-Flash

SHA1 for the RAR: 08c5b22a8a7c920f36e686c503b99c523b9ac68f
SHA1 for the modified BIOS: 12b101c9fa8a0e5a70700ee7065ba1678346e618

Mods on the BIOS:
Speedshift Enabled by default
SGX Enabled by default
Intel ME changed to 11.7.0.1261
Intel RST OROM + EFI Modules updated to 17.0.0.3713
506E3 Microcode CA updated for Skylake
906E9 Microcode AE updated for Kabylake
906EC Microcode AE added for Coffee Lake (9x00 Series 6/8 cores, P0 Stepping)
Updated EFI GOP Driver SKL-CFL - 9.0.1080
Updated OROM VBIOS SKL-KBL - 1062
Applied PCIe patch
Changed SKU to Z370
Set all cores sync
HT Patch (up to 16 CPU cores)
Patched ACPI tables

WARNING: The GA-Z170-HD3-DDR3 motherboard has 4 x Vishay SiRA12 MOSFETS on the low side which are rated for 20 Amps each @ 70°C for a combined total of 80 Amps, therefore I recommend to set PL3 TDP Limit (Package Power Limit) to 50W in the BIOS to avoid accidental overheating of the VRM's.

Hi, would anybody be able to give me some advice would this BIOS need modifying to work with any stepping of 9x00 series CPU, the change log says it supports CPUID : 906EC 6/8 Core P0 stepping.

However looking at the processors I wanted to is an i5-9400F, but this has CPUID : ‎906EA.

Would this BIOS need modifying to support it?

Thanks.

Thanks that's brilliant, I will order the CPU now, then flash the BIOS, and try swapping it over :-)

#5 RE: [OFFER] Gigabyte Z170-HD3-DDR3 F20 BI0S Mod with Coffee Lake support (906EC) by ipdialup 10.01.2020 00:40

Thanks for your help just to confirm I have it working today, I ended up with a U0 version, used some Capton tape to isolate the PADs all working a treat feels quite a bit faster than the old i5 6400 I had in there before.

Nice to move to latest GEN CPU without having to spend a load on new mobo/ram etc...

Quick Q, do you know if this BIOS would also support the i5 9600KF ?

Thanks.

@ipdialup The only Coffe Lake CPU's that won't run with that BIOS are 906EB - all B0 revision CPU's.

shixinyuan made this great post to clear up any confusion;

@chinobino
How long did you run the Z170-HD3 with the 9900k .
Are there any problems with the daily use ?
Thank you

@benobi I ran the 9900K in that motherboard for about 3 months.

Just remember that this board is designed for quad-core and cannot run the 9900K at full speed as the VRM will hit maximum temperature and power draw.

If you set PL3 to 50 Watts you can protect the VRM and the CPU will still clock up to 5 GHz on light loads - on heavy loads it will reach ~2.8 GHz (AVX) to ~3.6 GHz (non-AVX) on all cores depending on the specific program but you must also have sufficient cooling.

@chinobino Okay thanks . I plan to use the 9700k.

Updated both the F20 and F21f modded BIOS to allow flashing using Q-Flash.

@chinobino, hello, tell me please, will skylake (i5-6500) still working on this BIOS? Have it any advantages in comparison with f5b?

#12 RE: [OFFER] Gigabyte Z170-HD3-DDR3 F20 BI0S Mod with Coffee Lake support (906EC) by chinobino 31.03.2020 15:29

@lighteagle Yes it will work with either of these modified BIOS although you can also download the official BIOS from Gigabyte for that CPU.

The F20.x and F21.x BIOS are for Kaby Lake support and have the newer red GUI with some differences, notably SpeedShift is enabled (and can be disabled).

#13 RE: [OFFER] Gigabyte Z170-HD3-DDR3 F20 BI0S Mod with Coffee Lake support (906EC) by lighteagle 31.03.2020 15:39

@chinobino, thanks for answer. One more thing, is it "unlocked BIOS", which can overclock non-K cpu?

#14 RE: [OFFER] Gigabyte Z170-HD3-DDR3 F20 BI0S Mod with Coffee Lake support (906EC) by chinobino 31.03.2020 16:12

@lighteagle No, the only BIOS than can overclock non-K Skylake CPU are F5b & F5c (as long as you don't change the CPU microcode).

#15 RE: [OFFER] Gigabyte Z170-HD3-DDR3 F20 BI0S Mod with Coffee Lake support (906EC) by pilot53 29.04.2020 21:03

Does anyone know if this BIOS will work with a GA-Z170-XP-SLI?
