Vertex_FR

i've tryed crossflash Z790 to Z790 X but the tool is only supporting Z690 chipset.

Hello, you have to replace MCU on your bien by 015 version to be able to enable avx512. you can do it using MMtool and MCU file on HWbot discord

Hello, does it have box and bundle ?

you mean Mdie 24gb ^^' never tested this rev

Hello, you should try rdeq1, if i remember correctly it was needed for me on mdie for 7466c32 on Elite AX

i will need a non k bios too soon, dont want to try crossflash again

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

freeze arround 10160, started from 9200 with some modifications on the 86x112 profile

already tested with this profile with my 14600KF, i will have a try next time with others CPU ( 2 14600KF, 14900KF and 13900KS). maybe one of those should work better. need to be ready for cold session in few week

@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

dont do 1,4 1,45 set 1,3 1,4

and yes 1,54 v vddq and 1,5v vdd2 is really high. even for competitive oc. you dont have to push that much and vddq cpu is still lower than vdd2 cpu by 0,1v. just for exemple 8400c32 is really easy on z690 tachyon for gb3 at 1,35v vddq and 1,45v vdd2 on my 13900ks

mc voltage are juste above mem voltage menu, cpu vddq (vddq tx in hwinfo) cpu vdd2 you have to find the right voltage for them. it's a sweet spot. on tachyo with 13th gen it's arround 1,35v vddq and 1,45v vdd2.sometime it's lower. there is no need for overvoltage. juste set 1,3 V vddq and 1,4v vdd2 under 8000 mt/s 1,35 vddq and 1,45 vdd2 above 8000 mt/s for higher freq you will need to play with vccsa, 1,2v is ok up to 8266, 1,25 at 8400, 1,3v at 8600. but like vddq and vvd2 you will need to find the right voltage for your cpu. for freq up to 8400 you can use rdeq mode 2, above 8600 you may need rdeq mode 1 for mem voltage, tachyon need to have a gap between vdd and vddq(vddq mem not vddq cpu). 0,1 v between both on mine above 8000 mt/s

i have a Z690 tachyon with the same kit on a 13900KS. i can get 8000C34 daily stable, bench up to 8600C34 on it. for xmp there is nothing to change inside the bios. If it's too difficult in your case to get it stable try this : 1.2V SA 1.3V VDDQ 1.4V VDD2 RDEQ mode 2 Flare mode + DDR bus response at 3-5 (i didn't try wirhl mode for now) if it's not working try 1.35V VDDQ and 1.45V VDD2

hello, you must have to flash the last x7p bios for z690, it's the same as z790 and z790 x. there is no reason to crossflash to z790 bios
