Now that the OC Formula is available for sale its time to learn some tricks to using it.

Lets start with an overview of where all the necessary components are.



And some fun new buttons on the edge.



Normal restart is as it sounds normal restart. You will use this one primarily like you normal would use normal restart button.

Hard restart is new and its excellent. Perhaps the nicest feature that has been added this generation. This is for when your restart button wont restart for you and you have caused a bad crash IE. PCH has lost communication to the CPU or you may have noticed on z170 MOCF when you have pushed your mem to the limit and restart wont work. Before you would have to flip off your psu switch. Now you can use the hard restart button.

Safe Boot will be for a situation where you cannot train etc and you dont want to clear cmos and lose your profile you can press the safe boot button a couple times while booting and it will start in safe mode allowing you to go to bios and make changes to your current settings.

Next we will checkout the heatpipe VRM cooler.


Being an OC board ASRock has used a proper VRM cooler featuring fins with plenty of surface area and a thick heat-pipe that extends on to the IO area. For normal benching I dont even use a fan on it in an open environment. On ln2 I would suggest removing the VRM cooler and going bare board. The Cold for the cpu pot is plenty. If you leave it on your session will be very short and very wet.

Underside shot


Overclocking

SkylakeX when you arent worrying about power phases and vrm overheating and you have confidence in your motherboard x299 overclocking is simple. It's heat management. Its no magic that on water cooling using 1.35v you are near the limit of the cpu's thermal capabilities. On ln2 we are using only around .17v more than water. Water you will be lucky to hit 5ghz on a 10 core and on ln2 some can hit 6ghz. This shows you just how much the temperature is the key. So if you want to get the most out of your CPU then you will delid it and use a Liquid Metal TIM such as Thermal Grizzly Conductonaut etc. The temperature savings is around 30c at 1.25vCore on the 10 core.

If you are unaware there are two size dies for skylakeX. LCC is low core count and is 6/8/10 core. HCC is 12/14/16/18 and is almost twice as large. HCC with all that extra surface is running like a completely different cpu than the LCC. That is why you will see some 12 cores are running higher freq overclocks than the 10 cores or lower. All about getting rid of that heat!



Keeping temps in check we are ready to pop into the bios where there are a couple things to keep your eye on.

Benchmark Tweaker you will want to enable. Will do some behind the scene magic to create some extra bandwidth among other things to enhance your benchmarking scores.


Always keep an eye on if have quad channel. Some CPUs are more sensitive than others to things such as System Agent voltage. Also as always IMC's will vary and some cant be pushed as high as others without dropping channels. If you add or remove any memory its best to clear CMOS before trying to boot again.


The FIVR page is where you are going to want input your System Agent voltage Core voltage and Mesh Voltage. There are also SA and VCCIO voltages in the Voltage page as well but setting them in unnecessary Ive yet to touch them at all. Also dont forget you need to set both sets of vdimm.




Normal Conditions water cooled profile
45x CPU 32x Mesh 100bclk 3600mhz mem
2.1vInput 1.2vCore 1.3vMesh +350 System Agent 1.800vDimm

Max safe ranges for water
-2.1 Input voltage set it and forget it
-1.25vCore is about the limit for undelided, and 1.35-1.40 if you opt for a LM tim
-1.40vMesh on the ones ive tested that is around the peak for scaling should be around 34-36x
-+400 System Agent

FAQ What is mesh? Mesh = the new name for cache.

Some information about input voltage. Input voltage can be thought of as the voltage that feeds the other voltages of the CPU. If you just keep raising vcore and vmesh eventually you will require more input voltage or you will cripple your performance. If you test only with a program like prime 95 it wont even fail but the performance will truly be around half if you are too low on input voltage. So you must be careful with what you think may be stable or if buying a pretested chip etc. You should require an efficiently scored benchmark at least to gauge the chips quality.

For example the only difference between these two results is the input voltage




I follow the school of setting 2.1v input and never needing to touch it again on water cooling. You should not experience any issues with 2.1v even up to 1.4vCore and 1.45vMesh.

Liquid nitrogen.
Seems best to set most voltages in the OS. Boot around 2.1 Input and 1.25vCore. If you boot super high voltages you may find that you are dropping cores once in os.
Most benching will be done around -90c to -105c. There seems to be a scaling wall around 1.53 - 1.55vCore on most of the CPUs maybe a thermal limit where voltage doesnt help.
The sweet spot for mem seems to be 3600-3800mhz depending on the bench. X265 and geek seem to like as much as you can manage. All the others you will find even dual channel is giving the same as quad.

Cold bug might hang code 15 let it sit there and heat up and try restart button once you are at proper temp.

@Nickshih

As of the latest bios the motherboard doesn't seem to give any power to devices when the system is off; USB for example as well as any motherboard LEDS. This is rather annoying as the only time my Logitech Powerplay mat can actually charge my mouse is while the system is off. If i can recall this wasn't an issue with the stock and previous bios update you provided in this thread.

on bios 1.16

Can you and the Asrock team take a look at Taichi X299's BIOS? "Auto" sets VCCSA/VCCIO to 1.35V (1.36-.38V according to HWInfo) by default when used in combination with an 7920X and 4x8GB G.skill 3200 CL14.

it is fine .

u can play with those volt. normally it requires 1.25 both or higher to support very tight timings .

I don't have the design for charging devices with standby mode .

Do u know which bios version is fine for you to do that ?

I got lots PM about how many watts can be handled by best water looping system (ambient) on X299 OC formula

450watts -480watts output (cpu real watts monitored by intel internal tool )is the highest value by testing on 7980XE for 10 hrs here so far . CPU temp is around 99-102 C.

The power transfer eff rate of PWM is around 88% when pwm phases are under loading around 80-120c

So it means that 480watts / 0.88 = 545 watts go into both cpu 8 pins .

If you are using platinum 80 plus psu . it will be rated around 93-94% from AC to DC.

545 / 0.94 = 580 watts .

I will say 600-650 watts continued from PSU AC will be the max value you can see from your setup . Unless you are having any better cooling solutions .

I think that will be plenty for me.

Are both M.2s connected over the chipset or do they share bandwith with e.g. the PCIe x4 Slot? Could not find anything in the manual so I guess it must be over the chipset?

Yes both M.2 share the lanes from PCH.

I dont like the lanes of M.2 from CPU on this X299 platform. It means that i need to go through quick switch 3 times for supporting both pcie and sata type M.2 on both Skylake-X and Kabylake-X cpus.

It will make the signal from M.2 becoming so bad and pcie slot too .

The only bios that seemed to function entirely for charging devices was the bios the board ships with (not sure if that was 1.10).

I've found that bios 1.13a and 1.16 allow for charging from the top two USB 3.0 ports on the rear I/O, but no others.

Also, for the sake of comparison, when I had my powerplay mat connected to my ASUS CH6, while the pc was off the indicator light for charging status was the only thing on. When plugged into the two rear USB on the OCF that seem to support power while the pc is off, the powerplay mat is completely powered on (LED lights and all).

I used 4133 XMP setting a little bit last night, no issue with it, booted right up.

By setting the XMP profile for my memory, the bios bumps the bclock to 103.4 automatically. (so realistically it's the 4000 memory divider plus 3.4 on the bclock)

Just wanted to clarify that I did not select a memory frequency divider of 4133 in the bios
