Crosshair VI Hero: UEFI build update thread

[Dreamer1]

I think we need more information on bios options. There are plenty of options in the Crosshair VI bios without proper explainations and that’s why we just leave them in AUTO. It would be better if there are explanations to each options so that we can manipulate them properly for a best output.

Let's be civil. Your MB might be broke... BUT you nowhere mention that you renamed the file into C6H, and last time I DOWNgraded from 1201 to 1001 the BLUE LED was blinking during the flash and had a steady light when finished. All my UPgrades I do via BIOS internal flash program and there I don't bother about the blue led.

I tryed on my second MB - the led stops blinking as is off when the update is finished. This board goes back.
And no, i did not mention the renameing process since its obvious how it works. But i specifically wrote that i tryed both methods.

I was stuck with 1403 and finally flashed 1401 and and I am able to do 3200 on ram without errors. But CPU error happens and need to set volt for cpu to offset + 0.05 and all good. I want to go back to 9945 but it won’t go back.*

Does it require more CPU voltage when you have higher ram speed?
For example, 3333mhz to 3466mhz? or 3200mhz to 3600mhz?

i was going to say no but then remembered my having to set my first power state to 4.050 instead of 4.075. so yes it did require more power. instead of upping the voltage i dropped the clocks. 25mhz isn't noticeable and performance is still very good. cheers!

When I set 2666 MGz, timing settings don`t applied. On 2400 and 2800 all`s fine, but when I choose 2666, any timings and 2t mode doesnt`t apply and set to default from xmp and 1t mode. Checked via cpu-z.

I had a similar problem with Kingston HyperX 2666 Mhz on BIOS 0902 when I set the ram to DOCP 4 it came up with the wrong timings and voltage but worked, but when I set the DOCP to standard it picked up the correct timings and voltage. I was only able to update to BIOS 1403 recently all other beta and released BIOS I couldn't update. It now shows all of the ram settings from from 2133 2400 2666 2800, 2933 and 3066 so will be overclocking soon. It is a Hynix chip on these ram sticks but 2933 should be achievable.

I have the same Memory as you and mine runs @ 2933Mhz
My timings are 16-17-17-17-35-66 1T Voltage is 1,35v
Maybe those timings are working for you too.

I noticed when I moved from 1401 to 1403, my "auto" core voltages got bumped up a little. Not sure I like that because the average 1800x voltage is getting close to 1.4 volts without overclocking.

Had a big problem today. All of my fans just stopped working and the PC shut down do to thermal protection. There has always been funky stuff going on with the fan controls but WTF!. I have seen the fans slow down to idle and not respond to temps on several instances, but this time they just stopped. I rebooted an all is working fine now. Has anyone else experienced this before? I'm on bios 1403 and have use the Q fan tuning and set a custom fan profile. All fans are in DC mode as they are 3 PIN fans. Any help would be appreciated.

Kingston HyperX 2666 Mhz, 16Gb dual channel, same voltage and clock, timings are 14-16-16-17-36-63-2T, stable, tested in Linx 0.7.0 during 2+ hours. But 1700x works fine only on 3.8GHz@1.33V. Can`t stable overclock it more, don`t understand why. Increasing voltage don`t resolve problem.
