    Are you sure about this? I assumed this bios had no lock for future flashing in place, but still needed to bypass the lock for getting it running first. (shorting or grub)

    I could be wrong so would love to get some clarification on this, might revive my Apex IX and grab a 9900K from somewhere.

    Edit
    Gave it a try and doesn't seem to be working on an unmodified board. Flashback doesn't start. The disk drive blinks for a second then stops.

    I first flashed with flashback and somehow broke it. CH341a is a cheap BIOS programmer with a tool called flashrom that worked.

    for 7700k,  bios mod is needed to flash modded bios , but is pcie mod (nuvoton chip) needed to boot like for the 8 and 9 gen cpus?  OR both needed for modded bios to work correctly even for 7700k ?

    also, ok to flash modded bios to 2nd bios chip and leave original bios using bios switch?

    You only need the BIOS flashed to use a 7700K. And it's okay to leave the other BIOS original. I did this myself in the past.

  3. One great feature missing from the Apex X BIOS that the IX has is CPU overclocking temperature control.  This is very helpful with my 7700K and I imagine it would be even more beneficial for a 9900K or KS.

    The temperature control options allow us to configure two CPU core frequency targets directly from firmware; one for light-load applications, such as games, the other, for more stringent workloads. Both overclock targets can be assigned separate voltage levels and temperature targets so that we can run games and light-load applications at higher frequencies than workloads that generate more heat. The feature works by monitoring temperature and then applying user-configured voltages and multiplier ratios when the defined thermal thresholds are breached.  -ASUS

    I've modded a stock IX BIOS (version 1010) that only has the microcode for the R0 stepping of 9900K and should work for 9900KS if anyone is interested in experimenting; send me a PM.

    Hello

    The Apex X (which the modded M9A bios is ported from) has supported the 9900KF since 1801 so you should be good there. Several users reported no issues with memory overclocking and 9th gen chips as well. 4133 is the highest divider Z270 supports and being you can't push BCLK above ~103... You won't be able to push 5K, but can run ~4266 at very tight timings.

    No need, usb flashback did just fine, I did only pencil mod for bios, and modded cpu instead of board

    Do both hardware mods need to be done to flash a modified BIOS via flashback? I tried pencil and a small screw driver to short the pins near the BIOS chip, and I may have had them soldered at one time, but flashback would not work. I didn't mod the other part of the board. I'm using a 7700k.

  6. @davidm71_2 You are the wiser man. I bought the open box ("all sales are final") before I saw the promo code that you must have used. Let me summarize how I spent about 10 hours swapping boards, coolers, sticks, redoing liquid metal, etc..  There's a happy ending at least.

    Swapped a 2.5 year old working 5+ ghz 7700k from a Z270 K6 to the Apex and it wouldn't post if the memory slot closet to the CPU was filled. So, I figured the open box mobo was bad... Swapped back to K6 and the 2 closest slots to CPU had the same issue so I lost dual channel. I figured I damaged my delidded chip from over tightening or maybe the Apex ruined it. It's clocking profile has changed..before delidding I could do 8 hours stability test at 1.28; great chip. Now, 1.22v @ 4.8 almost hits 100C..I remounted the cooler and socket countless times. I though maybe single channel was stressing it extra. Today, I was considering returning the Apex being my rebate was already approved and I decided to look it over one last time. There was one pin in the socket that was off by maybe 20 degrees. It was almost touching another pin which made it very hard to see that something was off. Anyway, my 7700K is now working with both slots in the Apex! I got no idea what's wrong with the K6 and can't be bothered with it anymore. I've only spent a few hours with the apex, but it's looking stable at 4133 CL16-16-36 stable with 1.47v. 4266 wouldn't post for me, but it's not a real divider; it increases bclk. I'm wondering if we can use the higher memory dividers that the Apex X supports with the modified BIOS. I'll probably give it a shot now that you confirmed the modded BIOS works with SKL; thanks for sharing that.

     

  7. Thank you for this thread fellas. I just got this board for $40 after a mail in rebate. It was an open box, but looked entirely untouched. Unfortunately I damaged my 7700K and only one memory channel works so I will wait a few more weeks to see if the 9900KS launches or if there will be 9900K discounts to compete with the new Ryzens. New soldering iron is in the mail. Can't wait to push my 3600CL15 kit.
