The GIGABYTE Z690 Aorus Master Mobo Review: 10GbE Rounds Out A Premium Board
by Gavin Bonshor on February 25, 2022 9:00 AM ESTSystem Performance
Not all motherboards are created equal. On the face of it, they should all perform the same and differ only in the functionality they provide - however, this is not the case. The obvious pointers are power consumption, POST time and latency. This can come down to the manufacturing process and prowess, so these are tested.
For Z690 we are running using Windows 10 64-bit with the 21H2 update.
Power Consumption
Power consumption was tested on the system while in a single MSI GTX 1080 Gaming configuration with a wall meter connected to the power supply. Our power supply has ~75% efficiency > 50W, and 90%+ efficiency at 250W, suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real-world values that consumers may expect from a typical system (minus the monitor) using this motherboard.
While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our testbed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers. These boards are all under the same conditions, and thus the differences between them should be easy to spot.
Non-UEFI POST Time
Different motherboards have different POST sequences before an operating system is initialized. A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized). As part of our testing, we look at the POST Boot Time using a stopwatch. This is the time from pressing the ON button on the computer to when Windows starts loading. (We discount Windows loading as it is highly variable given Windows-specific features.)
DPC Latency
Deferred Procedure Call latency is a way in which Windows handles interrupt servicing. In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority. Critical interrupts will be handled as soon as possible, whereas lesser priority requests such as audio will be further down the line. If the audio device requires data, it will have to wait until the request is processed before the buffer is filled.
If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time. This can lead to an empty audio buffer and characteristic audible pauses, pops, and clicks. The DPC latency checker measures how much time is taken processing DPCs from driver invocation. The lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds.

I wish this had dual LAN and used the 2.5gb Intel chip as the secondary. I'm sure the Marvell 10gb is likely fine I just prefer having the safety blanket of Intel as an option on all my PCs. Otherwise it seems like a winner so long as you're willing to drop that kind of money on a motherboard.This doesn't seem like a bad price for all of the stuff they've jammed in there, but it does highlight what I've noticed about DDR5 Z690 boards. It seems like they go from barebones to premium without much in between. On the DDR4 side there certainly seems to be a lot more in the middle ground which may simply be because nobody really put out high end DDR4 boards. Hopefully when RPL lands this won't be an issue for the corresponding new motherboards.

Intel 2.5Gb chip has been super buggy and many people have problems with it. There are multiple revisions of it and even third re-release still had bugs.Jp7188 - Friday, February 25, 2022 - link
I love big heatsinks, but this board takes it a little far. That m.2 sink is so tall and close to the vid card that the backplate on my card wouldn't fit. I had to cut down the m.2 sink to make it work, which is still preferable to no sink at all.Also, the VRM sinks are too tall to allow some cpu HSFs to fit. The notctua u12s clears the RAM but not the sink at the back of the board.

One other gripe, I can't get a trident z5 6400 kit to work above 6000. I checked gskill's qvl and sure enough this board is one of the few missing from the list. The board is listed on the qvl for gskill's slower versions of the z5.timecop1818 - Friday, February 25, 2022 - link

Why what's the problem ? Like you want to spend on a K series processor and an XMP kit and a top of the line Z series chipset for X series for AMD but want to run in on Stock OOTB clocks ? That's gigantic waste of money. Because you would be better if you do not want to tinker with a H series board and a locked SKU, save money.As for OCing itself, it's a great thing. Since people can get fun out of their tweaking the HW that they own make it personal. And get maximum possible performance out of it. Like people are not just dumb Apple iclowns who just obey what Apple says, Goolag is pretty much same now. PC is the last refuge for owning something and making it purely personal. If you have an issue probably you should stick with Apple products or something like a Surface or some BGA trash.

It seems like that is a lot of additional cost to personalize something in order to fill what is mainly an emotional want inside of the space of recreational computer usage. So a want within a want in a world full of needs - it may be an unwise choice to do so.Silver5urfer - Monday, February 28, 2022 - link
PC is not just a gaming machine. If anyone thinks so they should discard their overpriced PC and get a Console for $500. It's not a recreational computer usage either. A PC - Personal Computer acronym says it all. It became more and more customizable for x86 until the junk BGA laptops came into the picture taking away the customization and DIY factor.timecop1818 - Monday, February 28, 2022 - link
I wouldn't buy a "XMP kit" in the first place unless it was somehow cheaper than plain Samsung dram on a green pcb from the likes of crucial or Samsung itself. i don't need disgusting rgb crap or giant fins on heatsink for what is essentially running memory ICs designed for 1.35V (or whatever) at much higher voltages just because "you can". of course, it will fucking heat up. normal dram operation doesn't need heatsinks.Jp7188 - Tuesday, March 1, 2022 - link
DDR5 is still in its infancy. It needs high voltage and heatspeaders to approach the latency of DDR4. The non-XMP 4800 CL40 is a joke, so it's high V and heatspeaders for the time being.
