LN2 OC TIP

Basically the same as AM4 OC
Use the LN2 PROFILE, Depending on the CPU, the CB temp is different
If you have -90 to -100c always freezing problems after benching at -150C or higher, Some cpus need restart after -30c to -40c cmos clear

Thanks.

Any tips for LN2, differents compared to Zen3?

find sweet spot between FCLK and Cold but this is similar like Zen3 

thanks

anyone testing max clocks with 2 cores ?

not yet, I have SP116, so seems average chip.

@safedisk Bios 0802 seems okay for LN2 also, but is there any chance to get a working safeboot button ?

 

Edit: CB moved 10° down from -145 to -135

Ask AMD instead, afaik it's their implementation that is broken since it was introduced with Ryzen 5000.

i see. lets hope AMD can fix this because it sucks to cmos clear after every single crash

Do we still need to torch up to like +10 C to dial in memory like 3rd gen or is this part at least improved?

803 is out if you want to test, you can follow this spreadsheet for all boards https://docs.google.com/spreadsheets/u/0/d/19gqxeeAdUmkwgE0EvH4MlJ7meeDbEHYP-FHYW-PMyOk/htmlview#gid=522016589 but there is a thread for the Asus x670e on asus’s forums links in doc. I have trained Mem around -85 /-100 c. Pro tip, disable memory context restore. Clear cmos. Train it cold. Shoot got -65 for initial training after cmos clear. Load ln2 profile or whatever profile you use. Dump bring her down to say -85, f10. Of course, depends on same, dimms, cpu sample. I’m hoping to post a score tonight that is maybe close to safedisk

Seems, BIOS 0805 is relative fine!

Thank you !

Hey guys I have a new build with a 7600X, Gskill Trident 5 32GB DDR5 and the Asus X670E Extreme board and I cant get it to boot, just shows code 00 on the LED and the Oled shows 00 Memory

I have tried everything including single RAM stick on multiple slots, reseating everything, BIOS flashback to latest bios, nothing helps, do you think its a memory problem, a cpu problem or a problem with this board?

How long did  you wait for post? It takes some time, special first time...Also sometimes  helps directly shutdown PC by power button and again start for better post.

Also check, your DRAM is really inside correctly in the DIMM slot

Hey, here are a couple of things to try:

-if you changed uclk mode to sync/async, set it back to auto (or sync if you have fclk and mem clock in divisible values) - e.g. fclk = 1600, mclk = 6400

-reduce fclk (or set it to auto if you changed it)

-if you set manual DDR5 frequency/timings, or xmp, do the settings work for the above rules? if xmp is 6400, set fclk to 1600 etc. if xmp is 7200, reduce mem frequency to 6400 manually after setting xmp. **most am5 chips struggle to do more than 6400 but this may have improved with newer bios revs-if you're trying to boot above 6400, this might be all you need**

In my experience, only 2 of my chips will run high fclk in async, but my 7900X maxes around 1800 and is happiest around 1600. 7950X does 2100+, 7600X same

if all of this still gives 00, make sure your mem voltages are sufficient for freq/timings, then make sure things aren't too tight. hope this helps. GL

Hey there, thjs is a virgin boot, havent even seen the BIOS just stuck at 00 no matter what

00 like that usually indicates dead hardware. could be board or cpu maybe, have you tried doing a cmos clear? reseating the cpu?

Hi there I have, have even sent the CPU for testing and its okay, so Im guessing motherboard 

can anyone please share this Bios 0911 ?

7700 not X?

7700 X じゃない？ 

It's not an X. It's a 7700.
Is it worth a try?

If you mean LN2 it's a locked multi CPU

Anyone found that you have to clear CMOS after every crash and warm up on the Gene or am I missing something
