Hey all. Just got my brand new 870E Extreme AI Top mobo up and running since past weekend. Was gonna wait for a 9950x3d but didn't want to wait any longer so went for a 9800x3d instead. Coming from a long line of Asus top motherboards and still having a 670e Hero running on another pc with a 7800x3d.

I am very very positively surprised by this motherboard's feature set and even though the price is not cheap I do feel you really get value for money. The thing that really amazed me is the incredible well cooled VRM and M.2 slot compared to the Asus. What even more surprised me was how cool the dual mobo chipset runs compared to Asus. Makes sense though since the placement on the board is much better chosen. I've let the pc warm up in a realistic gaming scenario by running the game Throne and liberty at max graphic settings for over an hour then checked thermals as below:

Finally to my great surprise zero issues so far. Blazing fast performance and no weird instabilities issues here as I've gotten used to on the Asus side. This upgrade was kind of too good (easy) to be true tbh. Also the 10G onboard immediately worked fine with no issues.

I received it running the F1 bios for which 2 updates are available so far. Since I'm having zero issues at this point I'm even considering not flashing.

If there's anything specific anyone wants me to check just let me know.

I'm curious how 2x16GB memory overclock goes.

I'm considering this or Godlike which is like twice as much.

Since I needed more memory on this particular machine I went with a more conservative (and cheaper!) 2*32GB 6000Mhz@CL 30 so I can't really test pushing that kit as you would be able to with a dedicated and optimized 2x16GB set of modules.

One other thing I did notice though is that the expo profile immediately worked fine and stable without any need for further tweaking (unlike on my Asus X670e Hero where I tested that same kit and it immediately rendered Windows unstable until I enabled some extra advanced memory options in the BIOS.

I've mounted this board during this weekend and I am very happy with it. I updated the bios to the latest version available (F3a) and so far everything goes fine.

Once I installed the OS and some additional programs I realized about the following:

1. HWinfo only shows 1 chipset temperature. The first time I run the app showed 2, but now just 1. Any idea about this?

2. I have installed a Sapphire 7800XT Nitro+ and the graphics card is running at PCIE 4.0 x8 instead of x16. The m.2 ssd I have is installed (Samsung 990 Pro) in the M2A slot but as far as I understand, the PCIe x16 Gen 5 slot does not share lanes with the M2A. I don't remember if in my last computer if this card run at x16 instead x8. Any idea on this?

Many thanks!

Well, I tested the 7800XT in another PC and it runs the same, PCIE 4.0 x8, so it is the graphics card.

I will keep trying to figure out what happens with the Chipset 1 sensor.

Cheers!

Hi again,

Finally solved the Chipset 1 missing temperature. Asked in the HWinfo forum and a very kind guy quickly opened my eyes.

Literally his comment: "AMD chipset temperature measures the USB xHCI controller(s) temperature in the chipset. When the xHCI controller is not utilized (or switched off due to power management), the temperature won't be reported."

One solution is to disable "Allow the computer to turn off this device to save power" in Device Manager.

So, misteries solved for me!

oh wow was wondering about that as well and had no idea. Thx for sharing the solution.

Hy guys, with gigabyte X870 Aorus Elite how many nvme drives i can use without limiting bandwidth for 5080 Aorus?
Click to expand...
You can use the one on top of the first PCI-E X16G5 slot (M2A_CPU) without affecting GPU slot bandwidth.
The ones below PCI-E X16G5 (M2B_CPU, M2C_CPU) share bandwidth with the first PCI-E slot, thus GPU will run at X8 if occupied.
The last one M2D_SB which is limited to Gen4 won't affect the first PCI-E X16G5 slot, but PCI-E 4.0 X4 will be disabled when that NVME slot is occupied with the X870 Elite.

So tldr, you can use 2 without affecting GPU bandwdith outside of the 4. But the last one will disable PCI-E 4.0 X4.

But even at X8, the 5080 is not fast enough to saturate PCI-E X8 Gen5, so you will be fine unless you benchmark and want that last frame. You can see below, with the 5090 there is barely any difference. 5.0 X8 = 4.0 X16 which make up the majority of the systems today.

NVIDIA GeForce RTX 5090 PCI-Express Scaling

The new NVIDIA GeForce RTX 5090 is the first high-end graphics card that makes use of a PCI-Express 5.0 bus interface. Are you in trouble when trying to run it on PCIe 4.0? What about x8, like when an SSD is using up some bandwidth? We've also tested various PCI-Express 3.0, 2.0 and 1.1 configs...

Ahh, so Gen5 will stay anyway, even with three nvme SSD and i have the Gen4 x16 speed?

I think a lot of them are quote outrageous clks, but its only on 8000 series. Gigabyte does seem to have very good memory topology and I did 8000 very easy and was able to crank it down to c34 without much trouble.
It does seem like it can be very dimm vendor specific, and you probably have to to be lucky with CPU IMC.
I currently run 8133 fclk/uclk sync'd at 2033, but do have a stable 8200/2050 profile. Also have been able to boot 8400 and run basic benchmarks, but that has never got anywhere near passing TM5 and would require more voltage than available to the Master, so board selection may come down to voltage limits.
Will probably grab a Apex or Tachyon when available, just to see if it is possible to run 8400/2100 at looser timings, but similar performance.

Nico, Interesting Tachyon headline today....."Overclocker Achieves 10,200 MT/s With Dual 24 GB DDR5 Memory Configuration On X870 AORUS Tachyon ICE". by Sarfraz Khan • Feb 8, 2025 at 06:21am EST

I didn't see a specific setting for high voltage mode. I just input whatever voltage I wanted. I'm sure I could do better but this is what I've been running for now. View attachment 2684850
I borrowed the timings from Buildzoid's 8000C34 M-Die video, but I lowered the tRFC a bit as well as the VDD and VDDIO and raised SOC to 1.15. I also found the option under AMD Overclocking -> DDR Options -> PMU Training to make sure tPHYRDL wasn't mismatched.
Click to expand...
Can you elaborate on what you mean by checking if tPHYRDL isnt mismatched?
New to ocing memory so trying to understand what that means.

No luck yet. I realize the performance difference is likely less than 1%, which means I'd never notice the difference between 16x and 8x, but it's the principle of the thing, you know...? It should be running @ 16x, like it ran in my x570 Master, 3900X system from day 1, so that's what I want to see...;) Haven't heard a word from eSupport as of yet--either they are jammed up with questions or else they're still on vacation! Query is still marked as "new."

I'm going to do one last thing from my end today--I'm going to reseat the CPU to see if by chance I've battened it down with a bit too much torque. I'm not expecting it to work, actually, but it's something to do...;) We'll see.

I think it may be your graphics card not being compatible with the board because i have 2 nvme drives installed and running a aorus master rtx5080 and its running at pcie 5@16x.

That's not how pcie lane splitting works. They're physical lanes. If you use 3 Nvme's, and a Gen4 x16 video card, since it's sharing lanes, the videocard/pcie slot will go down to Gen4 x8 lanes.

I dunno why people assume with these new x870e mobos lane sharing shenanigans "oh, If sharing bandwidth at Gen5 x8, if I use a Gen4 GPU it will be at x16 lanes then"... No, it will go down to x8 no matter what Gen it is.... That's how it works.

Now, if that affects your actual FPS in games, that's another question....
