March 28Mar 28 Author With @auto microcode more stable? I’ve only tested it for XOC, was more stable for me at high Mem frequency

I’ve only tested it for XOC, was more stable for me at high Mem frequency I loaded the quick 8400 profile and changed the timing to 36-46-46-46-64, Trefi Max. Set memory voltage to 1.5/1.5. Left default 1.4/1.4 for TX and VDD2 and set SA to 1.25! Works awesome.

May 7May 7 yo guys need help with Z790 stuff, sorry if wrong board thread but I can't find one for the Z790H awhile back I had asrock timing configurator and asus memtweakit, however it stopped working on my installation of windows and it seems that attempts of reinstalling it is futile I tried the one from Maximus apex OC pack (M13ocpak1224b) and memtweakit doesn't show any of the timings asrock timing configurator says "driver cannot be loaded, re-install..." + "access violation at address 0042280E asrtc.exe 000000C" and just displays garbled timings afterwards have anyone managed to find a fix? Windows 11 22H2 22621.5189 Enterprise (not LTSC) @Mr. Fox any input on this would be appreciated, sorry for the ping
May 9May 9 It looks like Intel released a new firmware 12f. Speaking of which, are there any plans to put back the SP score feature to xO bios?
May 23May 23 Biscuits/C.P. score still exists in X7u, but doesn't seem to work with the 14900KS (never did from what I recall). Here's hoping to a new XOC bios with 12f and giving the score for that chip.
Sunday at 06:24 PM4 days X7u hi, how do I fix rgb so that what I put in the program works, and not always the orange one is shining ?
Sunday at 08:56 PM4 days X7u 👍 but 8800 I can't achieve stability at Apex with 8800, I managed to do it. voltage Apex 8600 VDD2 requires less than Tachyon 8600 14900ks sp106 -sp MC 86 VCCSA Voltage 1.25 VDDQ CPU Voltage 1.345 VDD2 CPU Voltage 1.45 Apex -1,4375 DRAM VDD 1.58 DRAM VDDQ 1.56 DDR5 King Bank 8000 48gb Edited Sunday at 09:03 PM4 days by diyavolik777
Monday at 05:03 PM3 days Wow, how the heck did you manage that on Tachyon?? Did you use either of the 8400 XMP/XMP2 presets?

Tuesday at 02:50 PM2 days first, I used these settings, set up timings and v+ disabled fast loading boot when I set everything up, I turned it all off and everything works 24.7 But the voltage VDD2 I have to overstate it, I don't like it. This needs to be fixed.!!!!!!!! sa higher than 1.26v+ leads to windows boot issues, which is also a problem. Edited Tuesday at 02:55 PM2 days by diyavolik777

Tuesday at 04:08 PM2 days I turned it off now, with these settings the latency is up to 51, with it off it's 49,5+-
