you're right, it sets back to CAS7 lol but still fun to see :P

Oh, I didn't mean to spoil the fun! :p:

Nice to heard it !!! my dram same kit as you :D, so time to update bios again but my kit working well for 2800 4dimm 11-14-14-35-1T, 1.65V !!!
with L1.14U bios :up:

Thx buddy ;)

will show u 2856 4dimm hyper pi later.... already have screen

Mat ready for front line :D:D:D

2856MHz is max ? or it max for IMC my chip IMC wall on air/water at 2920MHz hope i'll can manage it to 2900MHz hyper Pi :)

module limited ....

Nick i flashed 1.14X and it won't boot stuck at 0b code ??? what wrong i try rename from Z77OCF1.14X_User to Z77OCF1.14X it still same problem
for 1.14U it won't boot for CL12 well have any new or should be try for 1.14V ?

Edit : same problem for 1.14v still can't boot at CL12 for my kit but CL11 easy

Thx

Going to LN2 this baby tomorrow :D.

Hopefully get time to LN2 memory too. Stay tuned

Thanks !!! for quick update and well for update method it no problem but after success and reboot it stuck at 0b code for 1.14X

Thx

Not bad at all the new bios!

@nick

again a description concerning my booting issue!
When my machine is off, then I must give a vtt1 of 1.085 - then it starts...after the start, I can change the vtt1, directly while booting, to 1.064V!
Maybe the starting voltage is too low when the machine is switched off. When I reset the machine, i have no problems, just when it's switched off. Could you change something in BIOS to have a higher starting voltage with automatically lowering it, after detection of ram?

It is not my voltage issue. It is something related to the IMC training .

Bcz first time training is going from default to OC setting . Need the real stable VTT .

second time u can lower down a little bit for sure. but .... i still suggest that u use 1.12 or 1.15 . It is safe ..

Software update .

Formula drive update to 0.2.12

Timing Configurator to 1.0.7 , add lots advanced timings .

Rapid OC to 1.0.15

Also fix the issue of software skin become white when u disabled the windows theme .

^ Congrats on new WR....... 7.136 GHz! :clap::up:

Yep, nice :

This board rocks on ln2,

tested a new CPU and the 06 performance is really good.

and wprime is pretty efficient too:)

this chip has the worst IMC I have ever seen, 23 at 2133+ and the 2000 divider would just 00, but the board performed flawlessly and I have maybe 5 liters left for a quick run tonight:D

Loud that is the "Y" bios. it gave me 00 at any settings. also 23 at some, but never booted for me. Please go back to P or something to get your IMC up again.
