ASUS Crosshair Hero VIII (Wi-FI) Beta BIOS / FW 3101

[Karmal]

I'm testing this new bios for the crossfire hero viii wifi let's see if they solved the random reboots with 4 ram banks at 3600 mhz in the specisìfico 128 gb certified to asus but I doubt the power Kernel 41 is always lurking

his is my ram .. i tried 4 different bios also the last beta at 3600mhz in docp i restart this also happens at 3400mhz.. 5 bios came out within 2 months obviously there is something wrong with these motherboards

Can you post the full ram configuration. Without it, nobody can help you on this forum.

Using 4x8Gb Corsair vengeance RGB pro here @ 3600 ,no issues , it's likely a memory timing issue but regardless you and me are operating way beyond the specified support speeds (guaranteed viable operation point) of the Processors integrated memory controller , Even if the board supports such speeds and the memory is rated at 3600 there's no guarantee the chip can exceed it's spec that far.

so what would you recommend ... now i am testing them at 3333mhz let's see if i will have reboots

Is your memory AMD Ryzen ready , tested on Ryzen and is it set at Xmp.
This info will help people advise.

I would start at 3200 using the first four primary timings that the Xmp specifies and leave all others on auto with 5-10 mem test retries ,using 1.38 volts on ram to eliminate it as an issue.

Then scale the speed up testing as you go ,it took me about a week to get up to speed slowly testing as I went ,my memory wouldn't take well to tighter timings, it would randomly stop responding when heated for a few hours 100% CPU GPU load was applied at all times too so stable for me means stable.

motherboard crosshair hero viii ryzen 3950x hyper x HX436C18FB3K4 / 128 settings in docp windows pro 64 bit without touching voltages that I had already done without having stability

I started like this .. but idle restarts are always lurking .. under stress no problem why? before that i had 4 banks of 16 gb always hyper x at 3000mhz no problem .. i need 128 gb for editing and rendering and i got this ram certified on the asus site ,,, but what do they certify if it doesn't work?

You only get random reboots when the system is idle? How long do you stress the system?

yes the restarts are when the pc is not under stress and sometimes when I turn off the pc it restarts by itself

 

[VuurVOS]

If you use only 2 sticks out of 4, do you still have issue?

I have not tried but I still need 128 gb of ram at that point I put back the 4 banks of 16 gb ram I had before at 3000mhz

Disable Gear Down mode in the Bios.

Disable Gear Down mode in the Bios.

And power down too.

Disabilita la modalità Gear Down nel BIOS.
[/CITAZIONE]
you say it can work if it were that simple ..

 

[VuurVOS]

Disable Gear Down mode in the Bios.

Why should Karmal disable Gear Down mode? If Gear Down Mode is enabled the system will be more stable.

@Karmal Did you already had time to test it with just 2 sticks installed?

no I have not tried because I need 128 gb of ram at that point I put back the 4 by 16 I had before for a total of 64 gb those were stable

 

[VuurVOS]

You are comparing something which isnt comparable.

Did your previous memory kit use the same dram chips? Most likely not.
Did the kit ran at the same speed? I guess no since 3000MHz memory kit != 3600MHz memory kit

You dont really know if it is stable at 3600MHz. When you just use 2 sticks, the integrated memory controller will be less stressed.

1 kit tested 24 hours with memtest no errors
2 motherboard always worked with 4 banks of 16GB same brand of memory
3 I don't know this but with bios 2206 it has been on for 24 hours now and I have not had shutdowns with 128gb of ram .. but still early to say
4 I have not tested bios lower than 2311 and I am testing them now with 2206 and it seems to be stable even the cpu temperature has dropped
I do 3D rendering and modeling and with 64gb I find myself tight otherwise I kept the 4 16GB banks which worked perfectly.
if I buy a memory at 3600mhz and they tell me that it is certified I have to make it work at that working frequency not at 3200mhz otherwise I would buy one at 3200mhz saving money.
the 64 gb kit that I mounted before is of the same brand and same chip micron

Every time my computer shuts off on its own, its always because of timings, or a lack of vdimm. I almost gave up on dram calculator, I've had better luck on my own through trial and error. But I can see why people would want to use an app like that. Also not much difference between 3200 and 3800mhz 1:1 with fairly tight timings, about 10gb/s on reads and copies, 5gb/s for writes on my hexacore, and 10ns in latency. This is on a bone stock 3600XT.

You got this wrong. The motherbord is certified but your processor isnt formally specified to run memory at 3600MHz with 4 dual rank sticks at all!
Your 3950X only support 3200MHz with 2 dimms. Everything above 3200MHz is OVERCLOCK. No guarantee it will work. With 4 dimms installed the supported memory speed is even lower!

Please see:
https://www.amd.com/en/products/cpu/amd-ryzen-9-3950x -> System Memory Specification: Up to 3200MHz (This speed is with only 2 dimms!)

https://rog.asus.com/motherboards/rog-crosshair/rog-crosshair-viii-hero-model/spec/ -> Memory: 4 x DIMM, Max. 128GB, DDR4 3600(O.C.)/3466(O.C.)/3400(O.C.)/3200(O.C.)/3000(O.C.)/2933/2800/2666/2400/2133 MHz

In short, there is a (big) chance your 3950X is not capable of doing 3600MHz with 4 dual rank dimms.

the 64 gb kit that I mounted before is of the same brand and same chip micron

I wouldn't be sure about that! Also dual rank dimms? Dual rank behaviours diffrently and cause more stress on the intergated memory controller of the cpu.

Hai sbagliato . La motherbord è certificata ma il tuo processore non è formalmente specificato per eseguire la memoria a 3600MHz con 4 stick dual rank!
Il tuo 3950X supporta solo 3200 MHz con 2 dimmer. Tutto ciò che è superiore a 3200 MHz è OVERCLOCK . Nessuna garanzia che funzionerà. Con 4 dimm installati, la velocità di memoria supportata è ancora più bassa!

Perfavore guarda:
https://www.amd.com/en/products/cpu/amd-ryzen-9-3950x -> Specifiche della memoria di sistema: fino a 3200 MHz (questa velocità è con solo 2 dimm!)

https://rog.asus.com/motherboards/rog-crosshair/rog-crosshair-viii-hero-model/spec/ -> Memoria: 4 x DIMM, max. 128 GB, DDR4 3600 (OC) / 3466 (OC) / 3400 (OC) / 3200 (OC) / 3000 (OC) / 2933/2800/2666/2400/2133 MHz

In breve, c'è una (grande) possibilità che il tuo 3950X non sia in grado di fare 3600MHz con 4 dimm dual rank.


Non ne sarei sicuro! Anche dimmer dual rank? I comportamenti dual rank sono diversi e causano maggiore stress sul controller di memoria intergato della cpu.

but you should tell this to asus who tested my ram on ryzen 3000 and certified it at the end of november i had another kit certified by asus and it worked perfectly and the ram i currently did not appear in the vendor list .. it appeared at the end November

Hyper X HX436C18FB3K4 / 128 4x 32GB appears in the certified list
they should specify that it doesn't work at 3600mhz but it's not written

Maybe you should read the notes listed on top of the QVL: https://dlcdnets.asus.com/pub/ASUS/.../Memory_QVL_for_AMD_Ryzen_3000_X570-4DIMM.pdf

- When installing a memory kit, please adhere to the DIMM slot priority cited in the “System Memory” section of the motherboard manual.
- Please ensure all memory modules are from a single validated kit. Do not combine DIMMs from multiple kits—even if they are the same make and model. Mixing and matching DIMMs can result in failure to boot and compatibility cannot be guaranteed.
- At default UEFI settings, the memory operating frequency depends on the Serial Presence Detect (SPD) profile the kit is programmed with, which is the standard way of accessing information from a module. To set the rated speed of the kit, please select DOCP or apply manual settings.
- The stability and compatibility of DOCP memory kits that operate beyond the JEDEC standard is not guaranteed because it can be affected by the capabilities of the CPU’s integrated memory controller, installed devices, and the operating frequency of associated bus domains.

Re Crosshair VIII Hero - FW 3101 crashed (turned off PC completely) within 5 - maybe 10 minutes. I think this is an ASUS thing.

i guess asus is making a big mess with these bios .... 5 bios in less than two months .. to find some stability i had to go back to 2206 ..
it is not the fault of ram, processor or chipset .. the bios is the only thing that determines the stability of a system..
here asus is making a big mess
