    3900X + CH7 WIFI + 2703 = BCLK can't stay at 100

    @Shamino, 3900X + CH7 WiFi + BIOS 2703 = BCLK nevers stays at 100 even if manually set. HWiNFO says it's 98.8 and memory is 1581 (rather than 1600) and AIDA says 99.4 and 1590 memory. Auto and Default result in the same thing. In the BIOS it says 100 on the right side, though.

    might be wrong, but that sounds like you are using DOCP setting. change docp setting to manual should allow you to set the bclk to 100
    loading DOCP profile = bclk @ 99.8.

    Thanks, but I'm already on Manual and tried setting it to 100. No luck.

    Hi, I had the same problem, reverted BLCK to Auto (just write it) and it now shows as 100.00 in monitoring programs.

    Ryzen has no HW for accurate read back of BCLK.

    Use Ai Tuner Manual, set BCLK 100MHz, when you open HWINFO, click settings, select tab safety, deselect periodic polling. Other apps may still show BCLK not as 100MHz, but when you setup HWINFO as stated you should see 100MHz.

    Also use latest beta of HWINFO, Martin has updated how BCLK is calculated for Matisse.
