Most likely you'll run into temperature and then power delivery problems long before being unable to run OC'd with stability. BIOS overclocking depends on the BIOS, whether it has all the options you need and/or can recover easily when bad settings are used. Software overclocking is temporary and good for experimenting but may not be able to offer all the features a BIOS could. XTU is fine if your looking at an extra 2 bins and maybe some bclk for a ~300MHz increase but not suitable for running higher bins.

Wouldn't worry too much about the iGD. IMO you should start with default clocks and undervolt core and cache as much as possible under worse ambient conditions while checking stability. You will also need to check for throttling and see if your power limiting options are overridden. Once stability is determined at negative offset you might want to add ~20mV as a safety margin. You should aim for a power limit that prevents thermal throttling. Current limit can be set to 256A to avoid Electrical Design Power throttling. Note that VID decreases as the CPU gets hotter so you should test 8x multi also while cores are still hot from maximum multi's. Quite a few people stressed successfully at maximum but have experienced a BSOD when coming off load. If you do not have any thermal or power limiting then make a note of your vcore at 37x multi and your offset. To use the extra 4 bins start with 30mV per bin so 4x 30mV = 0.120V then set adaptive mode core voltage to Vcore37x - offset + 0.120 For instance if 37x Vcore is 1.000V and offset is -80mV then 1.0 - -0.08 + 0.12 = 1.200V With extra 4-bins enabled, core voltage set and offset set, stress test and if okay start reducing core voltage in small steps while again check for stability. Once stability is found again you might want to add 20mV for safety margin. Good luck.

Hehe, yeah just imagine if they used that small pin instead of the inside wall connection.

Be careful with the XTU benchmark, it is strongly affected by RAM. For instance my i7-4700MQ would run about 840 with 1600MTS CL11, changing BIOS timings to 1866MTS CL12 scores over 900. If you are looking for something stronger than the 4810MQ then make sure you have plenty of thermal headroom (cooling) to accommodate it.

Hi godfafa, sounds like your almost there. Easiest way IMHO is to install W7 as UEFI with CSM enabled. Better to use the W8 boot manager on the EFI system partition (bootmgfw.efi). Once installed with CSM, update all graphics drivers to latest. Add BCD option novesa (this is what can cause the starting windows logo to stay on the screen) bcdedit /set {current} novesa yes For Intel RAID make sure the driver version is at least 11.5 or higher. You may need to load driver for install (F6 type drivers) Reboot to UEFI BIOS setup and disable CSM (use full UEFI boot). May have to power off to clear old legacy OROM from system before booting. Secureboot can not be used with W7, fast boot or ultrafast boot, whatever your BIOS calls it, can be used. VBIOS for discrete card will need to be GOP compliant, integrated should already be okay. Good luck.

Are you booting full UEFI with GPT? There is no need to flash a modified BIOS to enable or disable other options such as hyperthreading with these notebooks. Here's the link I tried to provide you on how to enable the advanced and hidden options without flashing BIOS but replies seem to be getting tied up waiting to be approved for literally days.
