I think it´s still possible to find better CPU, will it be enough? Who know´s

X7T bios have problems with microcode switching, this is why I`ve removed that all and just let X7U online. It´s same like X7T but without any problems during microcode switch

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

Highest CL44 frequencies in Gear4

Nice Result Bro! Glad to hear it works better now :). Let me try my old dimm :D

WOW!!!

have removed the link to the X7S bios because of bug during microcode switch and add new versions (X7U) for Tachyon and Tachyon X. MC-Switch works now fine ###################################### Z790 AORUS TACHYON / X BIOS RELEASE NOTE ###################################### X7U 19/03/2025 1. Fixed MCU swap X7T 18/03/2025 1. Add 0x10e 0x11f and remove 0x11a 0x11d for Change MCU section X7S 18/03/2025 1. update MCU 123 to 12C 2. Add Change MCU 0x105 remove 0x10e X7R 12/03/2024 1. Added Microcode 0x123 for 0x671 ( RaptorLake CPU )

Small microcode update 0x12C. But I have had some problems with mc change yesterday. Update will follow, at the moment, please use auto selected mc

new bios versions for Z790 and Z790X are in the first post

which bios do you use? I don´t have any problems with X7p since long time

It’s time to rerun it with new version 👍

Time to sandbags battle ;)

don`t forget, I speak from 8400+

Some people don't understand that a microcode has nothing to do with Mem-OC. Microcode is used to customize features of a CPU but not to increase mem performance, other settings in the bios are responsible for that. Mem-OC strongly depends on IMC, mem and settings. If you have the wrong settings, the high clock rate will not work even with the OC bios. I use 8k CL32 all the time with my old 12900k without any problems, with 14900k you can also use 8400 CL32 for benchmarks without any problems. For 24/7 I would go to CL34 and use a little less voltage. My settings for voltage are very relaxed, SA 1.23-1.27, VDDQ/VDD2 1.325/1.375 - 1.40/1.45, depending on CPU and the memory clock.

He need to rerun it with new Y-Cruncher version, without it, don´t think he have so many backups ;)

Feel free for some updates

Still my USB-Drive 😉

Thanks guys! USB stick was empty, I filled it a little bit

Thanks guy´s. Yea pretty nice old chip. @Jason IMC it´s still not the limit of IMC but frequency

for the 12600HX you can use X7P bios, it works also fine. for the non-k cpu´s you must use Z790 X6V Bios because you are not able to select 0x09 microcode. This is why I´ve used Z790 or Z690 for non-K cpu´s You can also try to crossflash bios on z790x to the z790 X6V, somewhere here or in th z690 Tachyon Thread was documentation how it´s possible to do

Thanks bro! Still same cpu and each time is the score little better 😂

Sorry, haven’t tested it for stable 24/7 settings. But I think you must play with voltages. Especially with IMC voltages, without adjustment they will be to low

Just for Info, my 14600K works fine CL32 with 1.35SA/ 1.35/1.45 VDD’s my 14900k don’t need slouch high voltages, it works perfectly with 1.27SA 1.37/1.39 VDD’s Everything with CL32. this is why I say I’ve never had problems with SA Voltages. but of course different CPU’s needs different Voltages. Some like higher, some need lower voltages.
