Default New BIOS for i7-8700k - changelist?

Hello.

It looks like a new BIOS for the i7-8700K generation showed up on firmware downloads sometime after 3/25/2019. It's version 2CA and the full filename is E7B43IZ1.2CA.

As of today, the MSI LiveUpdate utility is not picking it up as a BIOS update.

The download package is just the BIOS file - no changelist, no installation instructions.

Is a changelist available?

The motherboard in this machine is an MSI 7B43. MSI has updated the firmware for that board 5 times since I purchased the Corsair One. There have been no updates from Corsair until now.

Perhaps the best answer to this question would be to tell us which of the multiple MSI updates this Corsair update is based on. Those updates are listed here:

https://www.msi.com/Motherboard/supp...-PRO-CARBON-AC

Aside: I was, and still am, thrilled with the One form factor and features. The lack of updates is awful, though. I actively recommend colleagues and friends away from it specifically because of this. If Corsair addresses this, you will have the unconditionally best small-form factor / high performance PC on the market. I hope you.

Just because the board we use is similar to the mass market one does not mean it's the same. Our BIOSes are tuned specifically for stability and fold in necessary security updates. If your system is running fine, listen to your motherboard vendor's advice: DO NOT UPDATE THE BIOS.

We don't regularly publish new BIOS updates at the same cadence as the motherboard vendors specifically because we have to focus on stability, and frequent BIOS updates are a great way to ensure novices brick their systems.

Can you please provide a change list for the posted BIOS so that I can make an informed decision? I have recurring USB and sleep issues. I also have unpatched microcode that has none of the Spectre and Meltdown mitigations that MSI started rolling out in March of last year.

I would seriously appreciate it if you answered my specific question about a changelist and also considered a less defensive response to my customer feedback about updates.

This BIOS will have those microcode mitigations introduced. And what specific USB and sleep issues are you having?

USB - I have an Oculus Rift headset whose USB is constantly connecting and disconnecting from the front port when idle. No issues when in use. I have a couple of other USB devices (e.g., a Garmin GPS that's occasionally connected) which do the same.

Sleep - Sometimes the One just doesn't go to sleep. Happens fairly regularly. Have investigated and adjusted all sleep-related BIOS and Windows settings since acquiring the machine. I'm no stranger to either BIOS sleep or Windows sleep settings and it doesn't seem settings related because it's a spurious behavior.

Regarding your disconnect issues with USB, are these duplicated with the rear USB port or just the front port?

For the sleep issue, what monitor are you using? You wouldn't by chance be using a G-Sync display, would you?

I haven't tried plugging the Oculus Rift into a rear port. I just plug both the HDMI and USB into the front port. When plugged in this way, the front USB frequently disconnects and re-connects - what I mean here is that Windows generates the "device connected" and "device disconnected" tones as the connection comes and goes.

My monitor isn't a g-sync display. It's an ASUS 32" ProArt. This one: https://www.amazon.com/gp/product/B01F6D1ITM

Another suggestion would be to try a different USB cable (assuming you have one handy) altogether if possible.

The Oculus Rift headset uses a single (4 meter) cable which is combined HDMI and USB. The cable splits into USB and HDMI for the last foot or so. I'd have to swap the entire cable out.

Thing is that everything works fine when the headset is in use. The issue is that it regularly connects and disconnects when it isn't in use.

Two MSI updates (7B43v13and 7B43v14) describe USB fixes. One update is specific to mice compatibility, the other just says "Improve USB compatibility". These were released in March and May of last year.

I'm planning to update this weekend.
