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

sergmann Posted March 27 Author Posted March 27 Old M-Die works also fine with X7P but don’t forget, old M-DIE can’t boot so high on Air. I was able to bench with 14900k up to 7200 1T and 7600 2T Quote
Lionson Posted April 21 Posted April 21 Hello, someone can help me? Im currently using z790 tachyon x ( X7R BIOS)- 14900KF 98 biscuits 8200 C38-46-46-46 or 8200 C34-46-46-46 error around 2-3 minutes in Karhu. SA 1.24 CPU - 1.4 - 1.45 DRAM - 1.55 / 1.55 rdeq mode 2 + flare mode... Temperature never exceed 30c What can I do to have a daily 8200 ? Quote
sergmann Posted April 21 Author Posted April 21 your voltages for CPU are to high. Try SA 1.2 / CPU 1,30/1,35 and check if it`s mor stable or not. You can also select directly 8400 profile which is stored in the bios, it works fine as start point Quote

I have the same board and 14900K. Here are the numbers that are going to work for you SA - 1.14v TX - 1.30v VDD2 - 1.45v Btw. If you don't want to waste your time waiting for Karhu to finish, run Y-cruncher and then play BF2042. If you have a slightly unstable platform you will get BSOD or hard restart in BF2042.

If it's not stable, can I increase SA ? Or even TX to 1.35? Quote

PEEQ Posted April 24 Posted April 24 Hello,does someone have F3 bios? XOC BIOS dont work with 14900ks whatever I do. Just want to try F3 bios even if its bugged / not enough good;;;;; Quote
freak77power Posted April 25 Posted April 25 (edited) 16 hours ago, Lionson said: Crash after 2sec of karhu It says VDD2 1.474 however it is set to 1.450v in BIOS. Also, it says 1.155 for SA but it is set in BIOS to 1.14. I use X7o BIOS. Also, make sure you cool that mem well. Every silicon is a bit different but this would be your starting point. I would leave RAM to default XMP profile, 8000 speed. You can tweak it later. Almost forgot, set your timing for RAM -> Flare. Also, leave the CPU clock speed on AUTO. Do not overclock your CPU until you find a stable overclock for memory. I hope this helps. Leave low latency and high bandwidth options to AUTO. You don't need to have it enabled because you will tweak your timings manually later. Edited April 25 by freak77power Quote
Zarok77 Posted April 25 Posted April 25 3 hours ago, Lionson said: Nothing works, Im gonna rma try 8200 c36-50-12-46-98 for daily. also 1.2v sa cpu 1.42 / 1.38 ram 1.55 / 1.51 assuming you talking about adie.... because if your kit is 48gb, make sure trfc is also set to 700 . good luck, you do not need to rma anything imho 1 Quote

Just want to try F3 bios even if its bugged / not enough good;;;;; I have tested on Z790 Tachyon X with X1a, X7p and X7r, everything works fine with 14900ks. Zarok77 is also with 14900ks on his Tachyon without problems. Also on Z790 non X everything is fine with it. If you are on non X board, F3 Bios is pretty old, I would try new bios for KS last one is 2 days old with better support for 14900KS https://www.gigabyte.com/Motherboard/Z790-AORUS-TACHYON-rev-10/support#support-dl-bios official bios versions for Tachyon X https://www.gigabyte.com/Motherboard/Z790-AORUS-TACHYON-X/support#support-dl-bios Quote
spit051261 Posted April 26 Posted April 26 (edited) Tachyon X works fine 😉 CPU was on LN2 but RAM was on air . It will run same speed and timings with CPU on water . https://hwbot.org/submission/5534422_ Edited April 26 by spit051261 Quote
sabishiihito Posted April 26 Posted April 26 No new XOC Bios incoming? Proper biscuits for KS, maybe some 24GB mem profiles? 1 Quote
