When I use the tool to increase bclk, it did increase the bclck in cpuz. What am I doing wrong?
It works if I only increase to 102mHz
Findings with Asrock W790-WS, Xeon SPR-SP D0, and BCLK OC (and lack thereof)

Normal no.I dont make anything only bclk set in bios 112.The A tuning program first step 113 then apply,next 114 then apply,latest 115 then apply.The 112 bclk wery first step on the bios set!
You dont see cpu-z the bclk clock,any program not see.Only on the Asrock A tuning program.

An update. Life loves to get in the way.
- Both CPU Core and Mesh ratios stuck at 21-22X, no higher than ~2500MHz sustained
- Voltage override: 1.2V to both cores and mesh
- Also tried +120mV offset to both cores and mesh to no effect
- Fed 1.38V VDD, VDDQ to DDR5
- VCCMDFIA increased to 1.00V
- VCCMDF increased to 0.65V
but no reliability above 110MHz BCLK is seen.
I am no longer able to POST if BCLK is too high, with the on-board readout staying at 00 above 114MHz. No effort is made to train RAM at that state.
The RAM I have is super old; 28th week of 2020 production (!?), and never clocked above ~5300MT/s on my ACE when it had a w7-2495X installed. In fact, messing with timings even slightly (40-40-39-78 to 40-40-40-77, for example) actually worsens BCLK overclocking, somehow.
I'll get new RAM and possibly a Q071 or Q077 MCC ES CPU; you all are welcome to make suggestions here. In any case, I can always reuse it for AMD TR (coping).

Finally, I'm more concerned about the fact that this board/CPU combination is limited by PL1~=350W during testing, limiting benchmark scores. I do not recall the ACE having this problem, but I'd still need to swap it back out and document this properly.
- I've set PL1/2 to 540W, which while read in HWINFO doesn't seem to be applying properly
- CPU Current limit override and limit are enabled and set to 1023.875A respectively, but this seems to have little effect.
Other notes:
- Disabling FIVR Efficiency Management causes POST to hang.
- I can corroborate that 4.04 BIOS update had to be reapplied using USB flash drive; from Windows, I also got bootloops as Bert reports.
- FWIW, current PCIe devices attached are Optane 905p and some RX 6900XT.
I've controlled for this in recent testing:

I'm suspecting I have weak RAM to some extent, and your experience may well be mirroring mine. I got to 113MHz far more sustainably with one DIMM rather than with four installed. The Asus ACE board wants RAM anyways, so it might be worth trying to get some more RAM for this Asrock board.

PL1 time window (max. 448 sec.) even works on my X13SRA - you may try that.
have seen up to 380W with Q03J on my X13SRA-TF in cinebenchR23 runs.
Ok this approach is not working for me. Setting BCLK on BIOS does not take advantage of the BCLK Engine:
For example, when I set BCLK to 112mHZ in BIOS, computer does not boot.
When I set the BCLK to 110 mHZ in BIOS, computer boots successfully but BCLK is shown as 110mHZ in CPUz/HWInfo not 100 mHZ as shown in pictures from Arabus. There are 2 pictures in the below link, check both of them please.

HWinfo shows std.gen value or measures with Timer.
set DDR to 4000 ?
can also mean your CPU work only up to 110mhz
silicon lottery
turbo frq
QAT (Xeon Ws do not have)
The big difference between my set up and others here is that CPUz shows 110MHz.
The pictures from Arabus shows them as 110MHz. Basically there is "Hyper BLCK Engine", it just works as standard BLCK overclocking like in ASUS for me.

Sadly, I am not able to repeat the same results here. For some reason, changing BCLK also changes the PCI-E speeds like on ASUS MBs. I am not sure what the issue is. For me, ASRock MB is same as Asus and there is no way to make Hyper BCLK Engine work.
maybe ASRock disabled it with latest BIOS or CS/ME ?
(maybe you have to downgrade the ME manualy, only a guess)
just check BIOS which is running on yours.
W790-WS_2.02 - 16.10.5.1583
W790-WS_3.01 - 16.10.5.1583
W790-WS_3.05 - 16.10.5.1583
W790-WS_4.01 - 16.10.5.1625
W790-WS_4.02 - 16.10.5.1625
W790-WS_4.04 - 16.11.15.1736

you should try a fresh programed BIOS chip to sort out NVRAM BIOS bugs
( BIOS update doesn't just overwrite the whole Flash chip, only some areas are updated )
