try my profile, this settings are working for all my tested CPU`s and Mem-Kits.

With 1,45 VDD/VDDQ and 1,55VDD2 I can boot same settigs with 7k

i have tryed you profile without modification on adata and team group, no post.

 

[sergmann]

Oh not good, don’t have Adata here for tests ?

[Vertex_FR]

but i can boot 6800 30 40 40 28 with a full auto profil with the following voltage:

SA : 1.2
VDD/VDDQ : 1.35V
VDD2 : 1.4V

any other settings for vdd/vddQ and vdd2 wont post

okay, i can boot 6800 c30 then increase bclk with GTL:

 

Work in progress :

Sa : 1.2v
Dimm vdd : 1.6v
Dimm vddq : 1.55v

timings set : 6800 30 40 40 32
training set : RTL
 

VDD/VDDQ 1.35V / VDD2 1.4V : used for full training  at 6800c30
-> able to bench at 6800C30, 6933C30 not possible

VDD/VDDQ 1.45V / VDD2 1.5V : used if no training needed at 6800c30 after train at 1.35v/1.4v
-> able to bench at 6800C30 / 6933c30 / 7000C30 / 7066C30 not possible

VDD/VDDQ 1.45V / VDD2 1.55V : used if no training needed at 6800c30 after train at 1.35v/1.4v
-> able to bench at 6800C30 / 6933c30 / 7000C30 / 7066C30 not possible

VDD/VDDQ 1.45V / VDD2 1.55V + increase of dimm vddq from 1.55 to 1.6v: used if no training needed at 6800c30 after train at 1.35v/1.4v
-> able to bench at 6800C30 / 6933c30 / 7000C30 / 7066C30 not possible


Nota : 
If i change vdd/vddq or vdd2 for 6800c30 training (initially 1.35v / 1.4v) it doesn't train at all, no 3F RTL training, just 2E - 54 endlessly

new test :

1.5v vdd2 not stable with full profile tight, 1.45v pass gb3 at 6933c30

1.4v vdd2 rebbot 6933c30
1.44v vdd2 pass 6933c30 , not pass 7000c30

1.45v vdd2 pass 6933c30 , pass 7000c30, not pass 7066c30
1.46v vdd2 pass djsiktra 7066c30 but bsod after that
1.47v vdd2 bsod

Your 3rd timings are to tight.

change it to 12-7-a-a-20-20-a-a-12-7-a-a-56-42-a-a

I'm borderline, even 7000c30 is running the edge 

[Vertex_FR]

I think 7000 will be my max in ambiant.

I will improve it for my next dice session.

[Vertex_FR]

This will be my main base for next bench session

You're getting there, very nice!

 

Done testing with X3i, gives me extra MHz compared to X3g, here's my screen:

Nice, i see it on Facebook. great job !

I have to test this bios too, maybe 7066 will be doable, but first i have to finish the writing of my test of Tachyon... I lost 1 day with my mem tests yerterday

[Vertex_FR]

bench profil, boot instant at 6800, then bclk up to 7000 with GTL

work with X3I

DDR5 7070 30-40-40, pre-testing done, looking forward to play with DICE to see how far the IMC can go

[sergmann]

I got Adata Kit for short test.

It`s possible to start with 7k with a little bit looser timings and it`s Geek3 stable up to 7.1k on my KS.

 

Voltage-Settings:

SA: 1,20

VDD/VDDQ: 1,35

VDD2: 1,45

Mem: 1,60

Nice, thank you.

i also switched to KS, no i can’t do 7000c30… max 6950c30. Need to solve it before next cold session

Serg, is it possible to start at 7K with your 12900K also?

Belive me, as soon you will make CPU cold, you can run higher mem frequency.

I can start with low temps my Air-Settings with 7200, if you will make mem also cold, you can go higher (7600 are not the problem)

I will restest this evening, i still have 5kg of dice from my last session from saturday. this time i will try with mem under dice too. 

 

[Vertex_FR]

Does someone have tested to activate rebar on X3I ? 
When i activate on bios it my windows wont boot. I got a error. I need it for my next session with dice, i will rebench the 6900xt because i'm not at my max

managed to do 6800 c32 1T stable once. when I try to reproduce, it either does not train or is unstable.

also my dimm slots seem to have vertical play when latches are closed and when I lightly touch a stick, it errors more or freezes completely. ask support?

very hit and miss training still, but when it works F6d clocks best for me

Nice ! i also can do 6800C32 on retail bios. not possible with XOC bios.
Did you try the patriot kit on the Tachyon ?

not yet, ux more consistent, apex higher clocks.

maybe when the tachyon gets a bios that can train 6800 on my board with tight rtl's we can talk LUL

I have 3 different boards here, one ES first edition and two final boards, don`t have any problems with slots. Did you "pressed" mem full in the slots? I use often Mem-Pot and don`t have any issues with it.

For your settings, change tREFI to the max settings, it will helps to boot easier.

I can see VDDQ in the screen with 1.7v, if it`s true, your mem will be very hot and fails after a short time, don`t go over 1,60v on Air. I set 1,7+v only if mem is cold.
