I tried with my QYFS EVGA RTX 3090 Ti FTW3, ASUS ROG RTX 4090 OC and both gpus have problem with 103 and more. This is standart situation. If you want go higher than 103 you must using older gpu.

Ok, that is impressive - having PCIe 4.0 gpu running at that clock, AsRock outdid itself. Are they doing PCIe redriving or something?

I am confused 2 pictures says different bclks. First picture says 115 mHz and other one says 100mHz. Which one?

AsRock have a Clock Generator, bclk overclocking without pcie(like some b660 can do 125bclk with 12400).

AIDA 64 and HWiNFO may not detect it, but overclocking does work.

only way to ne sure is to run a benchmark before after, if it scales with the higher BCLK or not.
Yes. Test it with benchmark before and after.
I don't want to be the bearer of bad news, but I think the settings in the ASRock app don't apply, but maybe it's just my imagination.

Wow, also the multi core cpuz score is very high.
To me this seems to work, although it feels miraculously unbelievable.

ASRock Hyper BCLK Engine.

Set some voltage offset and limit the mesh freq it may can do higher bclk.
Wow, this will be very interesting. Does this only kick in through the software under OS not without BIOS? Can you do BCLK 115 or higher with a modern PCI-E graphics card?

I know that these Xeon chips have a hard limit at 4.1gHz. I think their voltage table ends there so so you cannot overclock them higher.

As @RolloZ170 warned me and I can confirm that these chips may die if you play with voltages and bclks. And this is not because of overheating only so be mindful with overclocking. But at $400, these chips are reasonably cheap to test out for their amazing performance.

I'm just speculating. If it's AsRock Hyper BCLK Engine overclocking, PCIE should be not affected same as desktop platform.

I have a D0 MCC ES, it can set voltage offset. The voltage table always end at the max turbo freq of this cpu.

Risk and performance are always together. You need to be clear about what you're doing, it's ES + overclocking.

if you can confirm that these ES are easy to die don't do that.

I havd a D0 MCC ES, it can set voltage offset.
Can we test that?

1. Are you using any PCI-E 4.0 device like a modern graphics card?
2. Can you reduce the multiplier limit to 30 (In Asus, I can limit the multiplier) and increase the bclk to 125mHZ?
3. What is the QXXX on D0 MCC ES? I believe you can set the voltage offset on all ES CPUs via AI Suite.

I don't have w790 ws, I'm just trying to analyze why ASRock can does 115 BCLK. You need to ask someone who is actually playing W790 WS. ASUS is not AsRock.

Q077/Q071 can set voltage in ThrottleStop.
