for my 12700KF(& without Ecores), MCU aplying = no boot after save&exit
 even resetting to default does not help - Q-Flash Plus only

with x7d - no problem

Haven’t tested at the moment with 12th gen. But I have had problems with non-k CPU’s with x7 bios versions. New bios have multiple microcodes for 13th and 14th gen CPU’s inside, will test it in the next days with 14th gen to check how it with new bios

tell us more about tachyon x please

Can’t say something about it because I don’t have one. I think nobody have this board at the moment

can you make(&post) a bios version(X7J) without a module that changes(manually in bios) the MCU?

I'll change it to the right one(15) myself

Sorry I can’t. I can replace or remove microcode but it doesn’t helps. Possibility to change microcode is hard coded. I haven’t problems with X7e and 12th gen, my first places with 12900k and 12600k are done with X7e

not that  "replace or remove microcode" but remove(or stop working) module↓ that changes MCU manually in bios aka like official bios(without manually changing the MCU in bios)

sorry but this is not removable, not for me.

I`ve tested X7j now with 12900k, it doesn`t have problems for boot but with 12600k I have few problems. after everything was resetted. Let me play a little bit with different patches, maybe I can find a good combination for it and you can also start with another cpu´s without any problems

Hello, do we have a GTL tool with profil shortcut ? I need it for changing bclk quickly during bench.
 + - button on board can't be set to other value than 0.1 bclk.

Or do we have a CMD command line to change BCLK/Vcore/Ratio ?

 

[sergmann]

BCLK Buttons work with 0.1 bclk.

you can check GTL, I think you can create some profiles for switching BCLK

@sergmann have you tested  mem oc on x7j bios ? i can't do more than 8000 Mt/s on while x7e can do 8400c32. I will need a motherboard for ln2 on 14th gen but for now i can't do anything with this bios.

There is something wrong with it! X7j made my board screw up my 13 gen cause now after I loaded different bios could not even do 8000.

shortly after got 23 flash error. Will not even post!

 

 

[sergmann]

Hmmm.. strange, flashed now many times without any problems and Mem works with 13th gen also fine

not 100% stable at the moment with 13th gen but it works 

with 14th gen it’s already stable

i will reflash it, if it doesn't work properly i will go with x7e for dice session, 

next week i will have Tachyon z790. maybe it's just issue with z690

Do you by any chance know what is 23 flash no post?

[Vertex_FR]

tested on x7b x7e and x7j, x7e bios is the anly one to train 8400c34

It sounds strange. Please select both switches for Bios like on my picture and flash bios with q-flash. If it still not work, flash on same way X7e. X7e works also with 14900k/14600k but not with 14700kf ?

Try same Mem settings like my one and you need only adjust Voltage for Mem. Auto Subs don’t works well ?

that what i did, no post. if x7e work with i5 and i9 it should be fine 

[sergmann]

New X7L bios is on the first page with more microcodes for 14th gen CPU´s.

Don`t try this bios with 12th Gen CPU´s, it doesn`t work! Have tested it with 12900k, 12600k, 12100F and G7400T!

HI, i'm running the 13900KS under dice, but i can't post with dive mode and it's not even stable at 8400C34. do you have any tips for mem training and stability at - 80 C ?

[sergmann]

Contact me @FB bro, I think we can find solution for it

12700KF work if:

1/ E-core disabled(in firmware) before Q-Flash Plus(can be enabled after in bios)

2/ optional: Аfter save&exit  &press reset(or power off&on) on MCU apply with 0%

Does anyone know the exact value for z790 tachyon each stage LLC ?

[FengXi]

I would like to undervolt my cpu , but don't know what stage of LLC to choose also don't know what value of DC_LL should I set to match the LLC

[Vertex_FR]

4 day with Z790 Tachyon, 17k mem done.

thank to Sergmann for the help!
