EDIT: You DO need Ln2 jumper ON on many CPUs, it has been extensively tested and can greatly improve CBB and cold stability at boot. However don't short points, use a switch or a jumper header if you can as I recently heard about retail CPUs that couldn't boot with Ln2 jumper ON under aircooling but are fine on cold, I will update guide soon. Latest retail batchs have jumper header. T.21 (based on 121) with all unlocked volts and tFAW working below 16 is coming (quickly succesfuly tried up to 12 with ViVi), just finishing some more test on it when I get back to Taipei and will post it here. Not sure about the reboot issue, never had this @.@ but thanks for your feedback, will check!

The voltage difference is as explained in my guide: -0.25v on CPU ST/ST V6 with Ln2 Mode ON in CCL, but fine in BIOS. We are working to fix this in next CCL version already. However IO reading on retail boards is perfectly fine, there's only a difference on some old ES boards like yours. The 00 issue happen when you push CPU ST above 1.33v and shutdown board. I'll share the mod soon (really easy) but in the meantime you can bypass this by Power OFF PSU>Wait MB LEDs turn OFF > Power ON everything again and it will be gone. If you still have 00 it is either CBB or CPU ST too high for temp as explained in guide.

On most ES CPUs that I tested, ST didn't made any difference from 1.25v to 1.8v but below gave higher CBB, that's why I recommended to use at least 1.25v in my guide. However, I recently saw that some CPUs have a "wall" which CPU ST can help to lift once you push it. For instance, Vivi's retail 6770K can do 6.3G Cinebench R15 but it needs +1.4v ST to clock higher than 5.9G and we tried all voltages one by one; nothing else helped. Same thing with the now dead ES chip we used yesterday, it couldn't even idle at 6.4G with 1.25v and would crash straight when applying ratio in OS, but with 1.65v ST it ran 6.42G Cinebench R15 (we didn't try values in between, lower would probably have been OK as well). That being said, you really have to test all voltages one by one for every chip to see if it helps, as it seems all Skylake CPUs need totally different voltages from one to another. As stated in the voltage table of the guide, ST V6 needs to be set from 300mv less to same than ST as these voltages are linked together.

Yes but I think perf is still bunnyextraction with MPS Multiprocessor, @Sam OCX correct me if I'm wrong. Sam has better knowledge than me on MSI Z170 + XP, I really didn't bother. We need ACPI compliant BIOS but I doubt it will ever happen on MSI due to manpower resources. EDIT: Win10 is better for XTU. For Win XP, you need to use ASMEDIA SATA ports (7/8) with IDE mode enabled and integrate drivers in your ISO. Win7 Installation option will enable PS/2 emulation for USB ports, so if you use USB keyboard to install Win7 or XP you will need this. When this option is enable PS/2 port and USB storage will not work.

I use Vaseline You could do it if you wish but I never needed much on ES CPUs and values set in BIOS are correct (just remind it show 0.25v lower in Command Center Lite). I can do 6.3G Cinebench R15 on my best two 6700K with CPU ST/ST V6 Auto and ln2 mode on (1.25v). I tried up to 1.8v but it didn't do any difference above 1.32v.
