Z790 Hero Bios 1501 XMP Problems (Major)

AlexTodd
Level 8

I posted here a few weeks back regarding memory compatability problems with XMP profiles on a Z790 HERO and some 8000mts Ram.

Would i be correct in saying that  XMP profiles I + II only adjusts the timings of the ram. One is the manufacturers preset and the other being one tweaked by ASUS themself . "Only" being the operative word here , as in it should not affect any other parameters on the board outwith the RAM timings.

Combining kits isn’t supported by memory or board vendors

Where can I see supported memory or board vendors? Can I have a link please, do you mean the main Z790 Dark hero does not support cosair dominator 2x33 kit?

Inspect the memory QVL. Note the QVL only consists of single kits, as combining or mixing kits is not recommended or supported.

Which CPU are you using?   I used to have 13900K Delid.   With G.Skill 7200Mhz (OC to 7400) without any issue or loose the timing.   CL34.  Looking at your image Turbo speed 6000.  Is that manually set?

It's a 14900k and its all auto as it supposedly boosts to 6ghz

That CPU Temp is very high compare to mine.  Core Voltage is also very high.  I have 14900K set to SVID Behavior set to Best Case Scenario.    Try to set to Best Case Scenario.  It will drop those 2.  My MCE is also set to Remove all lift.

Sadly it wont even boot into windows when set to "Best Case Scenario" 😔

That’s because your CPU doesn’t fit into that category based on the SP score. Leave in auto, or set typical for SVID behaviour.
