Hi Guys, I have a QQLS Mutant and had that thing running in an Asrock Z170 ITX Board with no problems. I now switched to an ATX Board (MSI Z170A Krait Gaming), modded the bios with coffeetime 0.99 (same settings as Asrock Bios before). CPU posts and boots, but Performance is a lot lower. CPU only boosts to 3,3ghz all core and Intel XTU says I am restriced by Current/EDC even without loads. I played carefully with voltages but that almost insantly causes reboots of the system. Do you have any idea what could be wrong here?

Hi Guys,
I got another Board, an ASRock Z270 Extreme 4 and my QQLS refuses to post/boot.

This is my Bios:

Anything wrong here? ME? Thanks in advance!

Could be a problem with the BGA-to-LGA interposer. Did it come with the ASRock board? It may not work with other boards.

@chinobino : Thanks, but that CPU was working fine in another ASRock Z170 and also a MSI Z170 Board. PC turns on for a brief second and then turns off. Maybe something wrong with ME?

@chrisk2305 I will tag @dsanke to ask for help with getting the BGA 1440 QQLS to work on a ASRock Z270 Extreme 4 if/when they have time (thanks in advance dsanke).

Much appreciated!

Got to work thanks to @msm8960

Thank, it’s work with Asrock Z270 Extreme 4. (Need E6 method of plutomaniac’s [Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing before Flash bios)
“setup_var 0x68F 0x01” for who don’t have time.

@chrisk2305 Thanks for reporting back. So it seems your flash descriptor was locked and you couldn’t downgrade ME FW.
