sergmann Posted February 11 Author Posted February 11 For Z790x Tachyon and 12th gen CPU’s. You guys need 12900k for deactivation on e-cores and selection of 0x15 microcode. After it it save settings and replace CPU with another one. After it DON’T press cmos! Then you can run also 12600k with it. For me it works fine https://hwbot.org/submission/5479225_sergmann_y_cruncher___pi_1b_core_i5_12600k_(6p)_16sec_765ms 1 Quote

sergmann Posted February 12 Author Posted February 12 If you have 13th or 14th gen CPU`s try to disable e-cores and set for example 50/45 without e-cores. Reboot sys and power it off. Haven`t tested it but it could work. With G7400T I can start Sys also but couldn`t select 0x09 microcode. 1 Quote
Lionson Posted February 13 Posted February 13 Hello, Im currently owning a z690 tachyon. I want to flash it to z790 xoc, how can I do it ? How can I fix if it's brick the BIOS Port (I know that tachyon has 2 BIOS but just in case). Also, z690 can be flashed into tachyon x XOC ? Already thanks for answer if there is any ! Have a good day Quote

Have a good day You don’t need to flash XOC bios from z790, I have uploaded already X7p bios for z690 also in the z690 thread 😉 Quote

Vertex_FR Posted March 5 Posted March 5 @sergmann back to Tachyon X, the review will come tomorrow now i'm playing with gear 4 but i think i miss something. i can't even train over 8400 Mt/s in gear 4 while gear 2 train up to 8800 Mt/s. I've tryed bclk 100 + 84 strap or bclk 84 with 100 strap but nothing work above. under OS i can increase bclk to reach 9000-9200 Mt/s. my settings : SA 1,2V VDDQ 1,3V VDD2 1,4V Fuzzy + rdeq mode 1 or 2 mem 1,5 /1,4 67 126 126 126 127 Quote

It’s a good starting point. Not all CPU’s like Gear4, with 86x112 Profile you can check it really quick. please choose only slot b for Gear4! with good gear4 cpu and Mem you are able to start with 10k on Air and choose BCLK Buttons for frequency changing Quote

sergmann Posted March 8 Author Posted March 8 Select this profile and go for example to 80 BCLK. Check if you can boot it. If yes go up to 81 and so far to see what is max. if you have found your max boot-frequency on air, press in bios + button to see how high you can go with current settings. Sometimes it’s necessary to adjust Mem voltages for higher frequency as soon you will see red lines or green dots in the bios during pressing + button, you know it’s Mem. If system freezing without error in the picture, you know, it’s the limit of IMC. example for Mem error Quote
joe90br Posted March 8 Posted March 8 Hi, This board is Quad crossfire compatible? 2x 4870x2 and 2x 3870x2? Z690 was compatible, but is rare in Brazil. Thanks. Quote

Freezes at round 10200 so next will be testing different IMC voltages 1 Quote
Vertex_FR Posted March 12 Posted March 12 freeze arround 10160, started from 9200 with some modifications on the 86x112 profile 1 Quote
sergmann Posted March 13 Author Posted March 13 In the first post you can find new bios version with updated microcode for Z790 Tachyon and Z790 Tachyon X. I have also uploaded first bios release X1a for all ppl who want to try it 2 Quote
razerware Posted March 15 Posted March 15 where i can find new bios of Z790 TACHYON for my brand new 14900ks? ☺️ Quote
Vertex_FR Posted March 15 Posted March 15 where can i find a GTL tool that work with IMC and mem voltage ? I'm using XP version for my win 10 and Tachyon X with 14600KF but i can't change VDD/VDDQ DDR value or VDD2 MC value. I only have VCCSA. last version doesn't work for me Quote
sabishiihito Posted March 15 Posted March 15 (edited) No biscuits for 14900KS Edited March 15 by sabishiihito Quote

spit051261 Posted March 19 Posted March 19 What Bios and microcode for BCLK guys on Tachyon X 🙂 Quote
sergmann Posted March 19 Author Posted March 19 17 hours ago, spit051261 said: What Bios and microcode for BCLK guys on Tachyon X 🙂 If you mean Non-K CPU`s like G7400, 12100 I guess it doesn`t work. I got 12900k+12600k working but not G7400. Microcode 0x09 is for non-k CPU´s, you can select it, but it isn`t selected on correct way. Only Z790 nonX works fine with aold Bios with non K cpu´s Quote
Vertex_FR Posted March 20 Posted March 20 i will need a non k bios too soon, dont want to try crossflash again Quote
razerware Posted March 22 Posted March 22 (edited) hi, I’m using x7r for tachyon. I can boot on 8400 with a die, but cannot boot on 6800@7600 with mdie during my yesterday attempts. is this bios better for adie? Should i use f8 instead? Edited March 22 by razerware Quote
