CORSAIR ONE Z270 BIOS 4C3 Update SOP Important Note: This guide ONLY APPLIES to CORSAIR ONE systems equipped with Z270 motherboards and 7th Gen Intel Core i7 processors. Step 1 – Prepare a USB drive with the BIOS update files Download BIOS update from CORSAIR.com (or click here for direct download) and prepare a USB flash drive by unzipping the download file and copying the contents of the unzipped folder to the root of a blank USB drive (formatted FAT32). Step 2 – Boot to BIOS w/USB drive inserted Insert prepared USB drive into your CORSAIR ONE and boot to BIOS by pressing DELETE key until the BIOS screen appears. Step 3 – Disable Secure Boot in BIOS Once in BIOS, hit F7 and go to “Settings” -> “Advanced” -> “Windows OS” -> “Secure Boot.” Ensure that “Secure Boot Mode” is set to “Disabled.” Step 4 – Boot from USB flash drive Change the Boot Priority in “Settings” -> “Boot.” Change “Boot Option #1” to the UEFI USB Key (the prepared USB drive with the BIOS update files). Hit F10 to save settings and restart, the system should now boot from the USB drive. Step 5 – Follow prompts to proceed with initial BIOS flash Note: If the current BIOS is version 4QF, the following prompt will appear: Note: The system will reboot once during this process. Step 6 – Reboot to complete initial BIOS flash and return to BIOS to begin second flash] Press DELETE key as the system boots to return to BIOS screen. Hit F7 to go to “Advanced mode.” Select “M-FLASH”, follow the prompts. Select the “E7A66IZ1.4C3” file on the USB drive.

Hello all, I just put together one masterpiece, an MSI Enthusiast Gaming XPower Z270 Titanium main board inside an Air 740 case with an AX1200i however - it doesn't want to power on! :mad: Upon my first thoughts, I plugged the power in and flipped the switch. I could then see my main board controls were glowing red (there are power/reset/overclock/etc buttons directly on this board). I pressed the power button itself on the board (not the case) and then - nothing, a flash of all led and fans, nothing - total loop. Frustrated, I began to investigate these same issues on this forum and started the following tests: 1. Turned off the power switch on the PSU and unplugged it. 2. Waited a few seconds, plugged it back in and flipped the switch - same result. 3. Peformed step 1 again, then disconnected everything from the PSU and repeat of step 2. 4. Now for self test, just a whirl of the fan and no led. Again, same. 5. This time, I unplugged the PSU only and depressed the power button to ensure the PSU was totally discharged. 6. Now I again, plugged PSU back in and flipped switch to on. Attempted self-test with different result - a moderate fan began to whirl for a 2-3 seconds and green led would appear for same time then turn off. Now I'm thinking, why didn't that work the first time I did the self-test? :grrr: Baffled, I reconnect everything with still, no boot or should I say non-boot loop. I then thought that maybe my PSU was actually faulty (as there are tons of people with issues on these and the manual offers little troubleshooting). I then used the first sticky in troubleshooting a power supply on this forum. I once again, rinse and repeat of power cycle with nothing connected now but ATX cable and I disconnect it from main board. I then connect pins 15/16 with paper clip and this time connect nothing but fans (three Corsair SP120RGB via included controller) (only led power, as fans themselves go to the board). Now, I flip the switch and I get a different result. Upon this, I see no LED from the fans - my self test led goes green then solid red. If I am correct, does that mean this small load is functional? :confused: If so, I tried checking all my connections and they are solid to this board. It is a Corsair Air 740 case so I have a ton of room even with the H80i CPU cooler. I have not bothered to connect a GPU since I cannot get even the basics to boot. This is a new Core i7-7700k with Corsair 2x8GB DDR43200 RGB Vengeance installed in slots 2/4 as per the MSI manual. The main board is defaults so it shouldn't have any OC settings yet. As this is a completely new build, I'm not sure what to do from here. Would anyone assist me with some ideas of what I can do to check if the PSU is actually functioning as expected or do I need to do an RMA? How long is the RMA process if it is?
I was wondering if the Dominator Platinum kit CMD32GX4M2B3000C15 2x16gb 3000mhz DDR4 is compatible with the new Asus z270 motherboards specifically the Asus ROG STRIX z270e gaming motherboard? I dont see why it wouldnt work but it not listed in the QVL for the board and i want to make sure before i order it along with the rest of the parts for a fresh build. Also i read that its better to get the 2x16 kit instead of the 4x8 one for this board, is this true? thanks
