This looks more like a presentation of a hobbyist having some fun with golden sample cpu than a final product that offers anything special.

What more can this mobo offer compared to the crosshair hero with the same cpu and memory in a daily setup ? Any answer to this ?
(with ryzen 7000/9000 cpus, normal humanbeing cooling and normal dailiy voltages on both cpu and memory) (SOC: 1.435, VDD: 1.85 and VDDIO: 1.52 ???)

-Crosshair hero still doesnt have any memory supported more than 6800 mhz in its qvl list. (The offical web page havent been updated for months)
-706 bios is all over the place messed with bugs, people are whining about it.

And here we are to see testers having fun with their enginering sample motherboards and golden silicon cpus. Probably none of us will have that kind of cpus.

I am done with Asus false advertising in forums. First, finalize your insanely expensive ultra premium products that you sold to your customers. Do not release beta bioses and act like they are without any issues. Then you may start advertising your new premimum products with your influencers in the forums.

Asus, you should clean up your mess first ....
100%, hero stuck with broken 0706 bios for a month, no news and here we are with ASUS promoters promoting another overpriced and overhyped piece of crap that they will not support and deny RMA after you buy it.

I am also an owner of the amazingly overpriced PG32UCDM monitor that has received last firmware update half a year ago and is still riddled with random black screens, not waking up from sleep and other teething issues that should have been solved max two weeks after it was launched.
 
As a owner of a x870e Hero i agree with you 100%.

It´s frustating that paying that much we lack so many things. QVL ram is old. Like no updates since i have my motherboard.
Bios....next page.
The heatsink is huge but i couldt believe that only covers the capacitors close to the cpu. Behind the Ram nothing. I couldnt add a thermal pad cause the back plate only pass half.
The M.2 soickets for the ssd at the bottom only have the top with thermal pads. Not bellow like the other sockets. On top of that you have to unscrew a bit piece so you have to remove the gpu every time you want to access that area (and gamble removing the RTX 4090 every now and thebn with the power connector cable.....).
To access the heatsink for the 2 x870e chipsets you have to unscrew from behind so you have to undo the whole pc and put the motherboard out and unscrew (the thermal pads below the heatsink leaves much to be desired).
.....etc....740€ of motherboard!
Hi guys, told ya many times don't ... Here nobody listen ... Here coz I'am a BOT ... Here or nope ... be sure I'am a BETA tester ... Here ... just like you 👀

I know Taliti. Mistake done but i learned my lesson for next time. Mistakes are part of the journey and more important is to accept and fix when we make them.
That´s why yesterday i recomended theTomahawk or Carbon. Asrock and Gigabyte i dont like much.

Never thought you are a bot. I see in different posts you help people here so for me it´s something to praise.

Actually i´m provably going to repeat with msi with the 5090. My 4090 Suprim is still working well so I´m aiming for the Suprim again or the Liquid version.

Gotta burn that SOC with an OC board xD Wonder what default volts it's going to run at.

I had the lucky opportunity to test this board a few days before announcement, so i thought i could share my own preliminary results here, but do note this is very far from finalized results :)

Hardware used for my short test:

Delidded 9950X ES running PBO
ROG CROSSHAIR X870E APEX
2x16GB G.Skill Trident Z5 Royal Neo A-DIE @ 1.76 VDD / 1.55 VDDQ
Very large custom cooling with mora

First off we have some short karhu run, only 1 hour durations do to time constraints.
Core Tuning @ level 2 = over 10mb/s higher throughput then anything i managed on the GENE, ended at a wooping 372.3mb/s :cool:

View attachment 2690015


With everything open bandwidth drops alittle, but still much higher than anything else :cool:
View attachment 2690013

Also did alittle test in GB3 on the same boot which netted me a wooping 15.2k / 14.75k memory score which is very good for a 9950X i would say
To top it all off, 49k in Cinebench R23 MT while still running PBO ;)
View attachment 2690016

I also did a short 1 hour karhu run @ Core Tuning = legacy -> 53.9ns in AIDA64
Do note is pretty much only in AIDA the latency drops almost 10ns, while Clam latency stays the ~same
View attachment 2690017

All in all i can say from my short test that this board have sick memory performance/effiency, and VDD ceiling seems much better than other boards running agesa 1.2.0.2B
View attachment 2690021

Would recommed if your looking for a memory tweaking board (y)
Have been tweaking for a daily 8400MT/s tune, but there aint much to gain if any, have to losen timings so much for the speed increase...
This is still work in progress, but this is where iam at now:

Delidded 9950X ES running PBO
ROG CROSSHAIR X870E APEX
2x16GB G.Skill Trident Z5 Royal Neo A-DIE running 8400MT/s CL34 @ daily 1.68 VDD / 1.55 VDDQ voltages
Very large custom cooling with mora

Core tuning = Legacy

Core tuning = level 2

Few notes:
  • Same as before, legacy mode pretty much only lowers latency in AIDA64
  • There are very little real performance difference between super tight 8200MT/s and tight 8400MT/s
  • This CPU seems to cap out at 8400MT/s which i'm decently happy with, since i have never been able to stabilize it above 8200MT/s on any motherboards before. Think its the APEX is helping me here.
Still working on the 8400 profile, so things could get better if i manage to run it super tight
 
Hey look, they are doing 6800 1:1 mhz with an extremely rare cpu (@ SOC: 1.435V, which is know to fry x3d cpus before) and acting like it's the ability of the motherboard.

meanwhile my X870E Hero with the latest 706 bios, sometimes boot the gpu with pcie gen2, sometimes refuses to boot with the same setting that were working perfectly fine for 1 week.

just lol ...
what all is installed to possibly, (if not the boards BOIS fault) to push GPU to PCIE 2.0? I am currently on 2.0
Just curious as to additional equipment. Not doubting you.

What is difference between Tomahawk or Carbon? VS say ASRock Nova? ( which is what I have due to using a sound card and needing PCIEx1) I have until Jan 25th to return.
 
While I want this board, does it make sense for CCD based CPUs? 8000 - 8400 really does not pick up much steam at all. The board can easily support 9000 M/Ts, but the CPUs don't and even if you tune 8400-8600 you get very marginal throughput, etc. So, cool, yes, but other than an APU based CPU for OC records, is there even a point to this board?

Board seems to let me run lower memory voltages than before, for any given speed/timings.
Also kinda suspect i can run tighter timings than before
 
Most of what we (overclockers) do is pointless. We do it for pleasure, because we can and because we want to. It is not because it makes the world a better place. We can apply that same argument to all hobbies. Gaming, cars, motorcycles woodworking, etc. The value is the pleasure one derives from doing it more than anything else. In the end it's all gonna burn.

For sure. I have a 1000 hp bmw i totally get overkill. But if a car makes 600 HP at 28 psi, and 615 HP at 38 psi... It's like... Well, why bother? Temperature is going to be higher and more on the ragged edge. That's the issue with AM5 and memory speeds like yes we know we're chasing the last 1% but AM5 hits the wall hard on memory bandwidth compared to RPL or ARL while sure a 1 dpc motherboard can improve situations be it voltage or timings, at least on the other platforms going from 7200 to 8600 was a huge improvement and worth it (to people like us) to grab an Apex.

I've had the z790 and have z890 Apex I only wish the Dimm circuitry was the issue with AM5 memory scaling.

I have a niche question.

Have you ever tried using "ROG DIMM.2 CARD" and found any effects on memory overclocking ?

It looks like asus removed the m2 slots from the motherboard and made them optional to use with the dimm.2 card to clear the signal integrity.

The APEX have 3x m.2 slots on motherboard + the ROG DIMM.2 card for 2x more m.2
(but GFX PCIe lanes will suffer if you connect all thanks to AMDs manditory USB port policy on X870E)

I was always using the ROG DIMM.2 card together with one m.2 slot on the GENE when i was using it, and never saw any drawbacks.
Maximum BCLK i could run was 102.5 before the 3090 failed handshake.. System would boot into windows just fine, it was just no picture.
(all newer Nvidia cards seem to cap out at around this PCI Express speed)

On-die amd IGPU can handle upto and beyond 110mhz BCLK

Not sure if that answers your question

Thank you for the response.

Did you use USB type-c ports for IGPU ?

With "removed 2xm2 slots" i meant the ones those are connected through chipset. I know the ones connected directly to cpu are still there. And i am well aware of line sharing.

Did you try and saw any difference with and without the ROG DIMM.

Since it is placed very close to dimm slots, I wonder if using any m2 with ROG DIMM effects memory overclocking ? or you made all your tests with an m2 installed on ROG DIMM andd you dont know what happens if you dont use it?:)

I might have a chance to get my hands on an apex next week. and i just want to hear your opinions to save myself some time while doing benchmarks :)
 
Using more than 1 m.2 on board will handicap PCIe to 8x though iirc.

No, i mean IGPU as inside the raphael cpu
I remembered wrong, it was on the X870E HERO i used IGPU connected through the HDMI port on the motherboard
Still same BCLK limit applies

On the GENE i always used 1x m.2 slot on motherboard and 2x m.2 slots on ROG DIMM, so cant really tell anything about before/after.
Can only say that i had no issues running that setup, and i expects the same with APEX

Oh ok i got.
But i am still not sure why apex boards chose not to include hdmi/display port. does it have any effect on signal integrity. interesting, that is a topic i have no idea about.

Thank you nice explanation, but when i get my hands on the apex, looks like that will be one of the first things i am going to find out :)
 
Ehehhe. I have the gene and thinking about the apex too but let’s see. Price will tell

Well, it certainly wouldn't help. Any additions have the potential to add more noise. iGPU not needed for XOC

Related to bclk, I also have a niche question :). I'm assuming you were talking about the GEN when mention bclk 102,5.

Did you try it on the APEX?

As a context I would be looking for something like baby steps, below 101 bclk ... 100,5 or 100,7 ... to be able to play with RAM at 8000 Mt/s (to achieve for example 8050) or why not more (101,25 for 8100).
