**Overclocking and Cooling: A Look at the Z690 Gaming XDDR4 and Fractal Test System**

When it comes to overclocking, there's nothing quite like pushing your system to its limits. With the Z690 Gaming XDDR4 motherboard from Gigabyte, this is definitely a system that's going to be pushed hard. The board has all the features one would expect from a high-end motherboard, including 10+ Gbps USB ports, Wi-Fi 6E, and support for both DDR4 and DDR5 memory. But what really sets this board apart is its ability to handle extreme overclocking situations.

The system in question consists of an Intel Core i9-12900K processor, 64 GB of DDR5 memory, and the NVIDIA GeForce RTX 3080 Ti graphics card. This combination will easily push the system's power draw up into the thousands of watts. To keep this beast running at its peak performance, a serious cooling solution is needed. That's where the Fractal Design Meshify C comes in. With its sleek design and large surface area, it's the perfect solution for keeping heat generated by the system's components at bay.

The Fractal Design Meshify C is an excellent choice for this system because of its ability to dissipate heat efficiently. Its slotted design allows for maximum airflow, making it the ideal companion for a powerful system like this one. With its large surface area and mesh design, it can handle even the most demanding cooling tasks.

**LGA 1700 Compatibility**

One of the things that sets this system apart is its use of the LGA 1700 socket. This is not an easy thing to find in consumer-grade systems, but Fractal Design has made a special LGA 1700 mounting kit available for their Meshify C case. This kit is specifically designed for use with the Z690 Gaming XDDR4 motherboard and ensures that it fits perfectly.

If you're planning on using this system or another one with the same components in an older system, make sure to check compatibility before purchasing. Not all systems are compatible with the new LGA 1700 socket, even if they physically fit. The Fractal Design kit is available for free on their website, making it easy to upgrade your existing system.

**Performance Testing**

To test this system, we'll be using our custom-built DDR4 system and Spoiler Alert - we've already done the comparison! However, we're going to revisit that comparison in another video. For now, let's take a look at how the Z690 Gaming XDDR4 performs compared to its DDR5 counterpart.

In terms of performance, there isn't much difference between our DDR4 system based around the Gigabyte Z690 Gaming XDDR4 and our comparison system with DDR5. However, when it comes to power utilization, things get interesting. The Z690 Gaming XDDR4 is able to consume significantly less power than its DDR5 counterpart.

**Alder Lake and Linux**

One thing that's been a bit of an issue with the new Alder Lake processors is their performance on Linux. While the Gigabyte Z690 Gaming XDDR4 does support Alder Lake, there are some issues with scheduling and error correction. However, these issues have largely been addressed in the latest kernel updates.

The main problem that's been reported is with cluster scheduling, which has been withdrawn from the kernel to avoid compatibility issues. This means that users who were experiencing problems with cluster scheduling should now be able to rely on their system running smoothly.

**Conclusion**

In conclusion, the Z690 Gaming XDDR4 and Fractal Test System make for a formidable team. With its ability to handle extreme overclocking situations and efficient cooling capabilities, this system is well-suited for anyone looking to push their system to its limits. While there are some issues with Alder Lake on Linux, these have largely been addressed in the latest kernel updates.

For those who want to learn more about power utilization and performance differences between DDR4 and DDR5, be sure to check out igor's lab - they've already beat me to it! But don't worry, we'll be back with another video soon, where we'll take a closer look at the system and its performance.

**Level One**

And that's it for now. I'm Wendell, and this is Level One. Don't forget to check out the forums if you have any questions or just want to chat about your own builds. Until next time, stay cool!

"WEBVTTKind: captionsLanguage: enoh we're continuing our z690 motherboard coverage this is a z690 gaming xddr4 we're going to do a build with it and we're also going to talk about an efficiency power anomaly that's happening on z690 so even if you're not interested in the motherboard you can learn something because z690 has got some really interesting properties to it when we talk about power utilization and testing with high end gpus like the 3090 and the 6900 xt let's dive in all right first up let's talk about the motherboard this is the z690 gamingx ddr4 from gigabyte this is meant to be a relatively affordable option that can satisfy and tame the super power thirsty 12 900k and with the 690 i think one of the more important features of the motherboard is going to be vrm and power delivery because at the lower end i don't think some of the z690 motherboards are going to be able to fully unlock the 12900k but that might not actually be the whole story it might just be that some combinations of things actually cause the system to use more power it doesn't really hurt efficiency needless to say gigabyte advertises this as a 16 v core phase one vcc gt phase two vcc aux phases and 60 amp power stages with tantalum polymer capacitors this is also a gigabyte branded motherboard the aorus branded motherboards tend to be higher end and more gaming oriented and that kind of thing but i picked this motherboard out because i was spending my own money and this is the one that i thought was a pretty good mix of features now ddr4 there's the gaming x and there's the gamingx ddr4 with alder lake with lga 1700 you have to pick the motherboard to support whatever kind of memory you want to support so this is a z690 gaming xddr4 i picked that because it's ddr4 because ddr4 is cheaper and right now there's not really a lot of speed difference between good ddr4 and the ddr5 that's currently available on the market that won't always be true eventually they'll be really fast and affordable ddr5 but that day it's not today so in terms of motherboard support the manual advertises support for up to ddr4 3200. now if you're like me and you like to go download the manual for the motherboard before you look at it and you download the motherboard manual for this motherboard it will literally have ddr4 and 5 specifications in it don't let that confuse you if you pick up the ddr4 motherboard only ddr4 will work in this motherboard there is another version of this motherboard that is the z690 gaming x and that is a ddr5 motherboard and it's the same manual for ddr4 ddr5 don't be confused this motherboard locks you into ddr4 the other version of the motherboard locks you into ddr5 very important now i was a little off put that the ddr4 support was only labeled up to 3200 on this motherboard because usually there's you know they go wild with the ddr4 specifications and they have a lot of other stuff in there that's along the lines of something like oh yes we tested up to 3 800 or 400 or whatever so i got up a crucial ballistix ddr4 4000 kit to use with this motherboard to see how that stacked up it worked fine also got out my oloy uh 3600 kit that was 128 gig which by the way is the maximum that this platform is going to support whether it's ddr4 or 5 and that also worked at 3200 so that was pretty good 3600 was a little sketchy not perfectly stable and i did raise the voltage so maybe if you're running full memory density configuration on ddr4 128 gig might be a problem gaming with some games it can make a little bit of a difference but really almost all of the differences between ddr4 and 5 are inconsequential and unless you specifically know something about your oddball use case you shouldn't really worry too much about ddr4 versus ddr5 now i mean if you can spend the extra bucks and it's not a big deal to you then yeah by all means go ahead and do that but it's not going to dramatically improve your computing experience or anything like that if you're going to be rocking the integrated gpu with no add-in gpu for a little while because of the shortages and other problems ddr5 does help gaming a little bit but it's on the order of like five percent best case scenario and i've got another video comparing intel's igpu offering on the i5 with what you can get for about 300 from team red very pretty so um maybe check that out if you're interested in igbo gaming you might change your mind all right let's take a look at board layout because gigabyte's done something interesting there too we have a single pc express 5.0 slot and that is wired directly into the cpu that is all 16 lanes that is the only option there is a bios option to bifurcate this slot into by eight by eight if you have a pci express 5.0 riser card that gives you two by eight slots but don't no that's just it's not an option there's two more physical by 16 slots at the bottom edge of the motherboard those are actually both by four electrical and they're connected to the chipset one of the really amazing and magical things about z690 this time around is there is actually a ton of pci express bandwidth for once i have no complaints we've got 16 lanes of pci express 5 that's actually all wired into this primary white gpu slot and then we have the dmi 4.0 interface which is the equivalent of eight pci express 4.0 lanes that's 16 gigabytes per second to the chipset and then the chipset provides additional pci express 3 and 4 lanes plus a whole bunch of other peripherals but the interface from the chipset to the cpu is 16 gigabytes per second plus the pci express 5 lanes plus we've got four more nvme lanes from the top nvme slot just below the cpu to the cpu so that's 16 plus eight plus four pci express lanes on this platform or at least pci express lanes worth of bandwidth that's more than main memory bandwidth how bananas is that so i've got no complaints about that gigabyte has used almost all of that for m.2 connectivity so we've got our primary pci express 4 m.2 that's connected directly to the cpu and then we have three more below the gpu that are connected to the chipset it'll support up to 110 millimeter m.2s and yes we set up raid you can do raid 0 raid 1 raid 5 and raid 10. it doesn't require a v-rock module there's no kind of shenanigans about license unlock or anything like that as we've seen on past platforms if you've seen some of our past videos you know that you know we and everybody else basically struggled with that and basically wrote off v rock is a really promising well-engineered technology that was encumbered by um marketing mistakes that seems to have been corrected and i was able to use a bunch of uh keyoxia you know little tiny bga koxia m.2 as well as some samsung 963s it's basically opposite ends of the spectrum in terms of uh performance um to see what this platform was capable of now those keyoxy m.2 there's some of the very few m.2 that work really well in portable devices because they're so low power but at the really high end if you want pci express 4.0 and ultra low latency you know there's samsung 980s samsung 963 if you're in the commercial space there's a lot of options for m.2 running array 0 m.2 on this was a delightful experience and setting that up you got to enable some bios options reboot you got some hoops you got to jump through there's another video on that you can check that out let's take a look at the rear i o the rear i o on this motherboard is maybe a little unusual but i get why gigabyte did what they did save on cost let's take a look we've got four usb 2 ports this is meant for your low speed peripherals everybody still has a bunch of usb 2 ports i don't really see this as a big deal a lot of motherboards you know we got 25 gigabit ports do you really have that many five gigabit devices i mean really because your mouse running at five or ten gigabit doesn't really help you and then we get two 10 gigabit type a ports those are usb 3.2 is what they're labeled one of those is for bios flashback if we get a displayport and an hdmi out those are for your igpu on your intel non-f-series cpu because the f-series doesn't include a gpu our type-c port at the back here is a 2x2 20 gigabit per second port and then our other connections are 5 gigabits per second usb 3.2 and then we've got a realtek alc 1220 audio codec the premium audio codec from last gen is the the mid-range of this generation we've only got the two analog outputs plus an optical spdif so let's cut down a little bit but we do still have our front panel audio connections so you can use that since the outputs are programmable and still run a 5.1 setup if you really want to in terms of other connectors on the motherboard we've got an 8-pin and a 4-pin for cpu power we've got cpu fan and cpu optional 4-pin headers at the top we've got a digital and a 50 50 analog rgb header our standard 24 pin atx power connector things are a little different with usb4 and thunderbolt on this generation of boards so the headers are a little different but we do have that option on this motherboard stay tuned for more information about thunderbolt 4 peripherals and that kind of thing we have our six sata interfaces these are all six gigabit per second sata interfaces and some of those share resources then at the bottom edge of the motherboard we've got our front panel connection our cmos reset header four four pin fan headers our usb flash button so if you need to flash this thing if you need to re-flash the bios from like a usb stick you got to use the indicated usb port on the back plus you're going to hit this little button on the motherboard so that it will start flashing the bios while the system is off in order to you know update it for an unsupported cpu or whatever then we've got two usb 2.0 headers those are for you know peripherals all the more water pumps and things like that have an optional usb header uh you'll see that in our build that we do so this is kind of nice that you can connect usb 2 peripherals internally then we've got our header for the new serial peripheral interface tpm for an enhanced tpm header should we need it although it's got onboard tpm so it's going to be windows 11 right out of the box then we've got two more rgb headers on digital 150 50 and finally our front panel audio connections and yes this does have gigabots audio amp up solution although the measured signal to noise ratio wasn't really anything to write home about at about 119 db so not terrible but you know they're there's better the rear of the motherboard is nothing special there's no extra heat sinks or io shields or anything like that and the screw placement is a pretty standard atx layout so all in all it's a pretty vanilla box standard motherboard now for the build i'm retrofitting an older fractal meshfy case i love these cases because there's a lot of airflow when you get a system like this you're going to overclock and really juice it to the max this thing's probably going to pull between seven and 850 watts that's a lot of heat generation so the meshfi is a pretty good choice getting this slotted in for that system i'm also using the new fractal aio this is not an aesthetic based design this is something special from fractal but it's one of the coolers that i had that had an lga 1700 mounting kit now a lot of your existing coolers will be compatible with lga 1700 but the mounting pressure is different so you need to contact your cooler manufacturer if you're upgrading from something that you already have to ask if they have an lga 1700 kit if they do that'll make your existing cooler compatible with the socket that's used here just because it physically fits doesn't mean it's necessarily going to work there are some older all-in-ones and some older tower coolers that will work on the new socket physically but they need to adjust a couple of things in the mount to get the mounting pressure just right so if you can definitely use the kit from the manufacturer instead of just trying to diy it because the cpu might not be cooled properly and at this wattage that's dangerous for cooling look it's the fractal lumen it'll look pretty good through the mesh on the front of this uh fractal massify case this is the older meshify the newer ones are nicer now what's probably in retail at the time of this video is not compatible with lga 1700 but fractal has a free kit that you can get on their website but the global situation being what it is logistics might be a little difficult if you see one of these in retail or on an online store look specifically in the product description for lga 1700 compatibility otherwise you're going to be waiting for that lga 1700 compatibility kit now for our anomaly testing gonna need more than one system this is our ddr4 system and spoiler alert i've already done the comparison we're going to put that in another video you've actually got two videos you got to look for first is the results of the build how is the performance did i encounter anything weird no everything was basically working as expected in fact if anything that performance difference between this ddr4 test system based around our gigabyte z690 gaming xddr4 versus our comparison system with ddr5 which you've probably already seen the video for it's another system based around the asrock tai chi there's not a lot of performance delta in those systems for compiling for productivity for pretty much everything except 1080p gaming and the differences between 1080p gaming is marginal at best only with the highest end gpus but the power utilization the power utilization is something interesting i'm still working on that so you're gonna have to stay tuned for that for another video oh and in case you're wondering about alder lake and testing alder lake on linux with uh the gigabyte z690 linux does actually work really well but alder lake in general right now struggling a little bit with its scheduler on linux the very latest update on that is they withdrew cluster scheduling in the kernel if it detects a hybrid cpu which is an indirect correction for a different situation that has to do with acpi tables and figuring out which chords are the preferred chords as far as as far as the scheduler goes when xmp is turned on the behavior for that is different on different motherboards this one is mostly good although there was one scenario where i had enabled xmp and i got the bad behavior where it doesn't actually tell you which core is good most of the time it did actually report the correct course with xmp enabled and of course if you disable xmp which is crazy and you shouldn't do that probably um it was reporting the correct course so i really wish that alder like supported unregistered error correcting memory but it doesn't so there we are i'm wendell this is level one this has been a quick look at the z690 gaming xddr4 and our fractal test system that it's going into in order to investigate why when you use a different gpu the cpu uses less power even accounting for everything else check out igor's lab i think beat me to the punch on this check out their article on that in the interim but uh there's a couple undiscovered nuggets here or there's a couple nuggets that i'm sort of still tripping over this is our first test system of two probably about two videos away from a conclusion i gotta do another build and uh yeah look for that i'm one of those level one i'm signing out you can find me in the level one forums whoa z690 gaming x alder lake is weird but cooloh we're continuing our z690 motherboard coverage this is a z690 gaming xddr4 we're going to do a build with it and we're also going to talk about an efficiency power anomaly that's happening on z690 so even if you're not interested in the motherboard you can learn something because z690 has got some really interesting properties to it when we

xmp is turned on the behavior for that is different on different motherboards this one is mostly good although there was one scenario where i had enabled xmp and i got the bad behavior where it doesn't actually tell you which core is good most of the time it did actually report the correct course with xmp enabled and of course if you disable xmp which is crazy and you shouldn't do that probably um it was reporting the correct course so i really wish that alder like supported unregistered error correcting memory but it doesn't so there we are i'm wendell this is level one this has been a quick look at the z690 gaming xddr4 and our fractal test system that it's going into in order to investigate why when you use a different gpu the cpu uses less power even accounting for everything else check out igor's lab i think beat me to the punch on this check out their article on that in the interim but uh there's a couple undiscovered nuggets here or there's a couple nuggets that i'm sort of still tripping over this is our first test system of two probably about two videos away from a conclusion i gotta do another build and uh yeah look for that i'm one of those level one i'm signing out you can find me in the level one forums whoa z690 gaming x alder lake is weird but cool\n"
