https://www.nvidia.com/en-us/geforce/new...le-bar-support/

Support for additional titles will launch alongside our VBIOS and Game Ready Driver update for the rest of the GeForce RTX 30 Series family late March.

We'll see about Resizable Bar support sometime late March...
As it is my EKWB (waterblock) for the EVGA RTX 3090 FTW3 Ultra is due to be shipped sometime around March 19th.
In the meantime, some other parts finally made it through the latest US snowstorm.

Having said that with 24GB of GDDR6X memory I don't even know whether the feature will be needed, as some game titles are already smooth as glass.

It appears EVGA and NVidia are onboard for resizable bar and it depends on what CPU hooks are required.

Having said that, my plan is to update bios with latest CPU microcodes in UEFI so we'll see how far that goes...

Best response to date would be to wait and watch as the VBIOS and NVIDIA driver updates roll out in the latter part of the month.

In the meantime, I'll be flushing the water cooling loop...so I kind of limping along until the rest of the parts show up.

Edit: Further it looks like the 400/500 series AMD motherboards are first to use resizable bar. The distinction here is that the garden variety consumer boards have about 16 PCIe 4.0 lanes while the X399 workstation type motherboards have upwards of 64 PCIe 3.0 lanes. As per AMD:

https://www.amd.com/en/products/str4-platform

There are 64 lanes of PCI Express® Gen 3 connectivity in the AMD Ryzen™ Threadripper™ CPU. 4x lanes are reserved for communication with the AMD X399 chipset. Up to seven PCIe® devices may be connected to the system (not to exceed 60 lanes); additional concurrent devices may be supported with a PCIe® clkgen on the port or device.

It would appear Resizable Bar is more directed at the gamer centric boards rather than the full blown workstation boards which already have plenty of PCIe connectivity lanes.

Cheers

Friend of mine has the asrock x399 taichi with the beta bios that enables resizeable bar, and has a 6800 xt , and can confirm that it does in fact offer an improvements in some games, he has been seeing 3-10% improvement from not having resizeable bar. So asrock enabled it no problem, jus wonder what is needed to bake it into our bios...

@KraZy_SkitZy

Okay I put in a formal request to ASUS to enable the AMD feature Smart Access Memory (SAM) for the X399 and TRX40 chipset lineup.
They gave me a case number and will get back to me in a number of days or so.

I used a link to the MSI X399 Taichi beta bios (ie competitors are already enabling support) and the NVidia announcement:

https://www.nvidia.com/en-us/geforce/new...le-bar-support/

and my argument was basically that this is an industry wide effort with AMD's Smart Access Memory, and Intel chiming in:

https://www.techspot.com/news/88620-inte...ocket-lake.html

and given the X399 and TRX40 chipset are premium chipsets this shouldn't be too big an ask.

We'll see where it goes...

Edit: Ok, got word today my request for BIOS/UEFI on the AMD version of Smart Access Memory feature got escalated to the level 2 technical support folks at Asus.

Cheers

@osonos

Okay you are on BIOS/UEFI version 2001

I will post a number of BIOS/UEFI screen shots and see if you have them properly enabled:

Settings: NVMe RAID mode = Enabled



PCIe RAID mode = ENABLED for your adapter for where ever you locate an M.2 NVMe adapter



SATA MODE = RAID



NVME RAID Mode = ENABLED



You should see your RAID and non-RAID drives after rebooting with the above three settings.
You will then need to configure your RAID drives and/or any spares or non-RAID drives.



Physical Disk Properties shown



After doing the first setting above in the AMD PBS section where you set NVMe RAID mode = Enabled and reboot
you should see the RAIDXpert2 Configuration Utility



Physical Disk set = ON





Check your settings and see if they ALL match up depending on your individual drives....

Once your are back into Windows10 you can install the AMD Utilitiy program RAIDXpert2 and check your drive mappings and configuration as per the pic below:



Cheers

Has there been any further information on the resizeable bar?

#23 RE: [OFFER] Asus ROG Zenith Extreme BIOS/UEFI_v2001 mod ROM by hancor 13.03.2021 18:39

@KraZy_SkitZy

Nothing directly, other than being upgraded to the level 2 tech engineers.

But then this process is also dependent on AMD, NVidia, Intel who have all committed themselves to rolling this out in an orderly fashion.
I'd reasonably expect something in the next two weeks, as that is the stated timeline for all the major players.\
But then with Covid-19 everything is getting stretched.

Meanwhile my EKWB waterblock is to be delivered on Monday after a 2.5 month delay, so I'll be having a system flushing exercise in the next couple days anyway.

How much newer is the microcode in your modded bios vs stock bios? Have you found it has offered anything, maybe like broader ram brand and frequency support?

#25 RE: [OFFER] Asus ROG Zenith Extreme BIOS/UEFI_v2001 mod ROM by hancor 20.03.2021 18:57

@KraZy_SkitZy

Yes stability has improved with the newer microcode.
Depending on the Windows build number, and a number of preview software build, I've had the motherboard boot into 3200Mhz on 64GB of RAM.
Albeit, I had to juice the voltage up to 1.4V, if I remember correctly.
It was stable on 3000Mhz at 64GB of RAM, which is slightly better than the rated 2933Mhz of my 2950X CPU.
It has been rock stable, even in gaming, at 2933 with 64 GB of RAM.
If I drop down to 4 sticks of RAM 3200 Mhz is a breeze. Mind you I have two kits of G.Skill 32GB rated @ 3200 Mhz with CL14 timings.
Just did a sample bios with the latest microcode using UBU 1.79.15 but I'm in the middle of my water loop teardown.
Of course heat is the biggest enemy of all circuitry so I've availed my self of the following for my GPU waterblock:

Fujipoly/mod/smart Ultra Extreme XR-m Thermal Pad - 60 x 50 x 1.0 (& 1.5mm & 2.0mm sizes) - Thermal Conductivity 17.0 W/mK

In addition to watercooling loop (~20C drop), the thermal pads above will drop temps by roughly ~10C yielding approximately a ~30C total temperature drop for the graphics card.
On the stock cooler the EVGA RTX 3090 card runs in the 70-90 C when running benchmarks and the fans spool up 100%.
With water block and premium thermal pads I should get this down to the 35-45 C running flat out.

If I have a little extra thermal pad I may apply to the motherboard circuitry, in particular: ASUS Cooling Kit ROG Zenith Extreme AMD Ryzen Threadripper TR4 X399 motherboard $20.00 USD SOC heatsink helps keep SOC power delivery area cool and enhances DRAM overclocking potential Which you can find here:

https://www.performance-pcs.com/air-cool...coolingkit.html

This is supposed to help the SOC achieve better RAM overclocking potential, but replacing the cheesy pad with the above Fujipoly should yield better results.
Also plan to replace the thermal pads on the power stages, so we'll see how that goes.
VRMs I've mounted a water block: https://shop.watercool.de/HEATKILLERZ-MB...AMPAGE-VI-ACRYL


I'll update when I'm back up and running.

Cheers

i have 8x8gb kingston 3600 ram, an its been a breeze running at 3200 cas 16, but even one notch higher, the motherboard gets very unhappy. Ive found gskill to be garbage for any ryzen system ive built if thtas the brand you have been using.

#27 RE: [OFFER] Asus ROG Zenith Extreme BIOS/UEFI_v2001 mod ROM by hancor 22.03.2021 17:09

@KraZy_SkitZy
What exact part number are you using for Kingston 3600 8x8GB?

#28 RE: [OFFER] Asus ROG Zenith Extreme BIOS/UEFI_v2001 mod ROM by hancor 22.03.2021 20:03

@KraZy_SkitZy

Below is bios/uefi update on microcode only; which you can use the regular method to update; (ie. within the BIOS/UEFI no special methods required):

UBU detect:

ZE stock microcode:

ZE updated microcode:

Everything else is stock so you should be able to test out your memory further, depending on the cpu you've installed.

NOTE:

00800F82 - Ryzen 2xxx, Threadripper 2xxx
00800F12 - Epyc 1xxx
00800F11 - Ryzen 1xxx, Threadripper 1xxx
00810F10 - Ryzen 2xxx APU , Athlon 2xx APU, Mobile 2xxx APU

Thus other than the Epyc 1XXX microcode update there is nothing too much new over the BIOS/UEFI in the first post above.
Of course the interesting microcodes, for this particular motherboard are the ones bolded above.
Latest UBU has newer network and raid EFI drivers, so I like to iterate the changes and test them before I upload a more comprehensive mod
to the first post.


Cheers

Hans

Asus zenith extreme + 2950x is running 8x8gb kingston HX436C17FB3AK2/16 @ 3200 cas 16
Asus strix x399 + 1950x is running 8x8gb Geil GAEXSY416GB3600C18ADC @ 3200 cas 16
Both ram work flawlessly populating all slots @3200, one notch higher is a no go. Well i Can get 3266 on the kingston but memtest causes pc to reboot half way.

#30 RE: [OFFER] Asus ROG Zenith Extreme BIOS/UEFI_v2001 mod ROM by hancor 23.03.2021 01:29

@KraZy_SkitZy

I may have to manually tune/enter the cas timings on my G.Skill memory; so far I've just run the 64GB on cas 15 @ 2933/3000Mhz.

By upping the latency to cas 16 - 18 it may yet squeak out 3200/3600Mhz; which of course is cheaper than forking out more $ for the platform.

It is however a trial and error PIA
