ASUS Pro WS W790E-SAGE SE + Intel Xeon Sapphire Rapids SPR-SP

[RolloZ170]

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.

thats what we bypass with BCLK overlcocking. the multi remains same, but with higher BCLK the effective clock is higher.
just set a voltage offset. The disadvantage is always more package power draw.
with that voltage offset you may have to set uncore voltage higher...

I am suggesting/asking if you can try 125 bclk on your Asrock to validate that ASRock has decoupled bclk from PCIE?

the ASRock Hyper BCLK Engine replaces the BCLK source from PCH. PCIe & co remains clocked by normal 100mhz.
afaik this is possible since skylake.

This is awesome, Is it possible to confirm that by setting the BCLK to 125 and sharing a screenshot?

I thought Intel forced MB manufacturers to disable this functionality so non-K Skylake cpus cannot be overclocked through this mechanism.

Intel Shuts Down Non-K Skylake Overclocking

When Intel first launched Skylake, one of the first changes we noticed was the uncoupling of the BCLK from other system clocks. Not surprisingly, this led to speculation that overclocking non-K chips…

This is interesting, it is in the docs!

Hyper BCLK Engine

Hyper BCLK Engine allows BCLK OC on Non-K CPU's withoutthe "Non-K OC" BIOS for ASRock...

Not clear if it works due to conflict with Intel.

on skylade DT first i could set Core bclk to 110 (PCIe,SATA is other bclk source)
and after some time intel limited to 103mhz by microcode update.

but here the original BCLK is still 100mhz. intel doesn't know about the extra generator.

Wow, in that case Asrock is an amazing choice here. Anyone wants to buy my Asus WS790 SAGE?

you will need that extra clock on ASRock because you loose 4 memory channels.

 

[Bert]

you will need that extra clock on ASRock because you loose 4 memory channels.

Doesn't it also help to run these CPUs at higher clocks? It seems like we can overclock these cpus to run at 4.5gHZ if we can utilize advance cooling options like watercooling.

you understand you loose performance with only 4 mem.channels ?
if you close that gap with OC you will be again at start, maybe better stay at SAGE.

CPU 115x34=3910,Mesh 25x115=2875,Memory ? maybe 5420

got with Q071 (boost 1-16c = 3900mhz) CPU single thread 628 pts.
obviously the 115mhz BCLK is taken.

Yes. SAGE is has more memory BW and PCI-E lanes. ASROCK will not take advantage of the full memory bandwidth and all PCI-E lanes as it only wires 48 PCI-E lanes to the CPU.

Does Asrock thunderbolt 4 ports support video output? I don't see any DP in as I used to see in other thunderbolt motherboards.

from ASRock W790 WS manual. TB comes from W790 chipset.

Rear type C 2 port (thunderbolt 4, USB 3.2gen1, no DP)

Not sure who here needs to hear this, but the Asus Pro WS W790E-SAGE SE massively dropped pricing to $270 on their estore
The net provided a $10 coupon code as well
All in (free shipping) for $281

Just got my board delivered a day early, ordered on the 12th
For my pseudo HEDT build (original plans were for a far less ambitious i9-14900KS system) this monster came up and now I'm in "eff it" mode

Anyways, here's some eye-candy

Great choice. I have this board and is excellent. You are lucky that Asus has a store in your country. In my country motherboard costs same amount from day one.

 

[SyKosys]

Thing weighs a ton and looks to be built like a brick sh!thouse

I'm in no financial position to build this up just yet, working on my NAS box first, but that just gives the market time to drop prices on the W-34xx chips. Really REALLY geeked to get this board, and looking forward to losing my mind next year when I start working on it

Lucky? Yup, for a lot of reasons

So I have spent most of my day reading this thread and parts of the thread on ES CPUs..

Hoping to get some validation on my planned configuration in case I missed something.

I have already ordered a WS W790E-SAGE SE.

My plan is to go with the QYFU (8461V). Clock speeds are more important to me then a extra 8 cores on the QYFS (8480+). If there is another CPU that I should look at please let me know.

I see that that chip can do "Up to DDR5 4800 MT/s" so I grabbed 2x Micron 64GB DDR5 PC5-5600B PC5-44800 RDIMM 2Rx4 EC8 ECC REG MTC40F2046S1RC56B


So it sounds like 3 of the PCIe lanes on the SAGE board will be disabled with this setup and two of the NVME slots will also not work. Is this correct?

Also has anyone confirmed if the SlimSAS ports will work? I have a U.2 drive I would like to use with that.

I will also have to figure out how to connect the 3 NVME drives I need to the board. Looks like ASUS Hyper M.2 x16 Gen5 Card will work. Can someone confirm if I can just use this like a HBA and not use the RAID feature on it..


Lastly. Any input on what cooler I should use. I see noctua has one that should work in my supermicro 4u case, but curious if there was any other somewhat quiet options.

1) 4 slots (1,3,5,7) work at x16. 1 slot (6) shows up as x8, at least in my case with the QYFU.
2) Even a cheap quad nvme card works fine. Just enable bifurcation in bios. No raid stuff to worry about.
3) The Noctua is actually pretty quiet. Avoid the Arctic - its board mounting mechanism isn't as refined as the Noctua and it uses proprietary fans.
