Hello,

Could someone clarify whether using igpu from CPU is possible on z790 Godlike somehow. I am lost in specsheet and I really need to use my second monitor off the CPU.
 
How come?

It says per below in the specsheet of ace,

1x Type-C Display port - Requires Processor Graphics

9. USB 3.2 Gen 2 10Gbps (Type-C Display port)

Isn't this hub for connecting monitors?
I would just grab the Carbon unless you need ThunderBolt to be on the Back IO panel as it will take the TB4 PCI-E card
Do you need the Features on the GOD or ACE or would Carbon suit your needs better

Honestly carbon would just be enough but I need 4x USB 3.2 Gen1 Type A (Front). I think ace is to go. Shame godlike doesn't have igpu support, would really like to have it

Yep kind of seems like a bad thing to skip on an Intel Motherboard but The Ace definitely has the USB support you are looking for will just need to get a USB to Displayport or USB to HDMI Cable and they are quite easy to find
 
all it can be used for is as a encoding/Decoding Engine but not for any Graphics Output (EG decoding Video Streams like H265 ect or to render Files like in a 3D Program)

Did I understand your post correctly? Does Quick Sync work with Z790 Godlike?

The sole use of the PC in question will be for Adobe After Effects:
13900KS / 4090 / Z790 Godlike / 128 GB RAM

EDIT: Having already purchased the PC (just waiting on the last M.2 to arrive) I was mortified after watching a YouTube review saying that Quick Sync won't work. But on another forum I read that the older Z490 Godlike has "VCCGT phase, you can still use Intel QuickSync, but without an output on rear IO, graphic can not be delivered from GT.".
So the newer Godlike boards support Quick Sync, surely?

Thank you in advance

See here, the Z790 GODLIKE doesn't power VCCGT. It has 26x RAA 22010540 105A Smart Powerstages for VCore in teamed configuration and 2x MP87670 80A DrMOS for 1.8V AUX, so 13+2-phase teamed. Nothing for the iGPU, complete overkill for VCore.

Also, about 128 GB DDR5 RAM, this is known to be quite problematic, it will only run at a low speed. Forget getting something like DDR5-6200 to work there.
See my thread RAM explained: Why two modules are better than four / single- vs. dual-rank / stability testing, just today i added some more DDR5-specific explanations in 2)+3).

I see. I don't plan to use the IGPU itself. Do you know if it supports Intel Quick Sync encoding for H.264 and the like? Or am I in trouble here?

For 128 GB DDR5 I purchased 2 x KF552C40BBK2-64, which is QVL listed (Dominator wasn't available). For the board MSI's website suggests not going above 5200mhz when inserting 4 sticks. Frankly I'd be ok even with 4800mhz, so long as there's 128GB of it. Like previously, am I in trouble here too?
 
To my knowledge, all the accelerated media encoding/decoding happens in the iGPU part of the CPU, and would also require the Intel graphics drivers to be installed. This would mean you cannot use these functions if the iGPU is not powered by the VRM.

Kingston KF552C40BBK2-64 are not on the QVL with four modules, just with two:

They don't mean "two kits" with the checkmark at 2, they mean "two DIMM" = two dual in-line memory modules.
Now, this might be harmless, in that they had just the one kit for testing and not two. Or it could mean that there were major problems with four modules. Hard to say.

In general, i've been critical of the GODLIKE boards (since a few generations), same goes for the -KS CPUs, and finally for 4x 32GB DDR5 configurations. Ok, in your case, if time is money, maybe there is some sort of justification for a setup like this, but even then i wouldn't have chosen the GODLIKE. But i don't want to be too negative, maybe you have some other reasons for choosing the GODLIKE. It does have the best components on paper, i'll give it that!

Indeed, the initial plan was not to buy the Godlike, nor KS, though not for any particular negative opinion I have, but more due to pricing. The KS was, ironically, the only "K" available where I am. For the MB, I had to import it, but after reading negative reviews on Asus MBs (primarily Maximus Hero Z790) I avoided it due to issues with running 4 RAM sticks and went with MSI due to positive reviews on running 4 RAM sticks. I wanted to get ACE Z790 (though you've shared negative opinion on that one too) because of a ton of USB that I need and its cheaper price than Godlike - but the dealership didn't have the ACE model, only Godlike, so I went with that. It just never occurred to me that Godlike will not have iGPU support for encoding/decoding, even if there's no GPU output on the IO panel, and then I saw a YouTube review that came out 2 days ago about this issue... I never thought to check Gigabyte's MBs.

EDIT: The PC is not intended for gaming whatsoever, but After Effects + UE5, so if I can get the 4 RAM sticks to run stable at 4800 that will more than do. And hopefully for Adobe's products the Hardware acceleration (CUDA) will suffice.
 
I don't remember being too critical of the ACE, i see it as the high-end board of choice from MSI (if there's no UNIFY or UNIFY-X at least). But only if you need some of its features, otherwise, it would be somewhat of a waste, and you might as well get a good mid-range model like a Carbon, Edge, or heck, a Tomahawk. Because even the Z790 Tomahawk would have no problem with a 13900KS. The problems will be restricted to cooling the CPU itself properly, but the Tomahawk's VRM is up to the task. Also, the performance would be identical to the Z790 GODLIKE. As long as the VRM can handle a specific CPU, and as long as you have enough PCIe lanes, ports, and functions for your use case, then all boards that fit the bill will result in the same performance numbers.

As far as four DDR5 modules running at a decent speed, yes, the high-end boards tend to have a higher signal quality, because they're using 8- or 10-layer PCBs where the RAM signals are better shielded and the signals are usually cleaner. However, they likely still use the same memory codebase for their BIOS. So even the most high-end board can't work miracles if the problem is in the memory code of the BIOS. But yes, i will agree with this thinking, that if you want to use a "borderline" RAM configuration, the more high-end board models are generally more suited to that.

With any luck, you can get DDR5-5200 stable even with four modules. I just can't help but lament what a collosal waste of money and unused features the GODLIKE is for most people, and what an obscene profit margin MSI could establish for it. And the GODLIKE buyers are usually those coming to this forum, asking how exactly to perform a BIOS update or something basic like that. I'm always willing to help everyone, no matter their level of knowledge, but sometimes it's very clear that they have no idea what their needs are and what overkill they actually purchased, simply because they thought that the priciest is also the best.

You have at least a professional justification for building a high-end system, as well as an explanation how you ended up with these highest-end models of CPU and board, which are rip-off territory. So i hope that all goes well for you, and please don't hesitate to post any questions here on how to get it working optimally. I promise i won't post more things about how i dislike the GODLIKE board or -KS CPUs, i will only try to help. 🙂

Cheers for all your help! I bet I'll have more to whine about and will most likely circle back in the near future (I smell BIOS problems lol).

Couldn't agree more on these components being in "rip-off territory". On my end time is of the utmost essence, so I had to begrudgingly fork out the money for this one and get the PC set up asap - this is precisely why I agreed to import Godlike, as the wait for everything else would've been weeks vs days. But had I had more time to "browse in peace" I would've been perfectly happy with the K + ACE models or, as you said, a mid-range MB.

" I promise i won't post more things about how i dislike the GODLIKE board or -KS CPUs, i will only try to help. 🙂 "
Thank you, I've suffered enough 😅

Just wanted to report back that the hardware setup worked out well. Here's how it looks for now (still doing tweaks):
Note: I'm not looking to overclock the CPU, just to get it to run 95C or lower (preferably below 90C)

• CPU: 13900KS, 5600mhz all P-core (6hz boost on P1 and P2). Cinebench R23 temps 80-95 in the 10min Thermal Throttle test. Multi thread score 40556, while Single pass multi-thread score is 40880. Undervolted -0.090; I might go to -0.095 or -0.100, as temps go between 95 and 100 in a few instances during the 10min Thermal Throttle test.
• RAM: 128GB Kingston Fury Beast (KF552C40BBK2), XMP Profile 1 running stable at 5200mhz
• Motherboard: MSI MEG Godlike z790
• Cooling: Liquid Freezer II 420mm
• GPU: Gigabyte RTX Gaming OC 4090
• PSU: Corsair AX1600i
• M.2: 1 x 2TB Samsung 990, 1 x 2TB Samsung 980, 1 x 4TB Kingston Fury (SFYRD/4000G)
• SSD: 8TB Samsung (MZ-77Q8T0BW)

• HDD: 18TB Seagate Iron Wolf Pro

A friend of mine says (also on a MSI board) that the alternative to undervolting is to change the type of cooling and limit the CPU Wattage can get more stable temp results.

You're clearly knowledgeable on this stuff, any advice?

Cheers!

Glad it works at DDR5-5200!

Well, your cooling is already top-notch, so i don't see where you wanna go from there. Setting custom power limits is always a good option to cap the power draw at something that your cooling can comfortably handle. With your 13900KS, that's especially important. Even Intel admitted (in their reviewer's guide for it) that allowing higher power draw than even the 13900K becomes borderline uncoolable, quote: "Even the best AIO cooler may not be able to allow the CPU to maintain 320W indefinitely without thermal throttling. Intel used a 360mm AIO cooler for our testing which was able to keep our system running without thermally throttling in most cases."

Plus we have the expected outcome, that all that additional power draw (if you let the power limits off the leash) leads to virtually no extra performance, and how could it really, with 2-3% higher clocks tops. But power draw rises with VCore squared, and all that additional VCore to reach the psychologically important 6 GHz needlessly drives up power consumption. So yes, a two-pronged approach is best: Undervolting (there are several methods), plus lower power limits, specifically chosen for your cooling capabilities.

Let's check the sensors with HWinfo64. Run it and open "Sensors", then expand all sensors by clicking on the little <--> arrows on the bottom. Also expand the columns of the sensors a bit so everything can be read. Make it three big columns of sensors. First let it run in idle for a while (couple minutes), so the "minimum" baselines for the values are established. After a short time in idle, produce full CPU load with Cinebench R23, and after the 10 minutes, when the CPU temperatures have stabilized at the highest level, take a screenshot. This will show all the important sensor data at once, both for no load and full load. Then i can tell you what's going on.

In the end, it should be a screenshot with all the sensors visible at once, like this:

Followed the instructions, here's what I got.

Undervolted the CPU -0.100 (at -0.090 I was still getting occasional 100C).
Haven't tweaked anything else in BIOS.

Cinebench R23 10minute Test Throttling, score was 40500, if that's at all relevant.

Eager to see what you think!
