"At first you expect the headspreader on these to be too small, but they are very effective.
Teamgroup actually used quality thermal pads that are well placed plus good coverage on the PMIC.
I don't know what type of die these chips are, but they clock great!
I'm able to do 7000 m/Ts at 1.4vdimm bumped up from XMP(6400 34-44-44-88 at 1.35v).
I won't go into my other voltage settings, but please keep in mind that you may need to
do a bit of tuning across several different voltages depending on your CPU's memory controller and motherboard.
I've also tested 8000 m/Ts single rank sticks from Gskill, and I find
6400 dual rank to be very close in performance despite the speed difference.
Less than 1% difference in one game. I'd rather have more capacity than 8000m/Ts at the moment.
If 64gb or dual rank is important to you, then look no further. I find these the best 32gb modules as of March 2023."
Gigabyte motherboards lack 7.1 surround analog audio outputs.
Asus' Z790-P and nominally premium ROG Strix also both lack 7.1 analog outputs.
Asus recently own-goaled by AM5 motherboard overheating issues,
so MSI.
Don't need Wi-Fi, but may use BlueTooth
Z790-P has more back USB ports, but slower max DDR5 clock
Z790-P also has many more Internet reviews.
Alternative motherboards:
ASUS PRIME Z790-A WIFI: "AI cooling", Thunderbolt USB,
Gen 5 PCI graphics slot, but no Gen 5 NVMe.
MSI MAG Z790 Tomahawk WiFi: good VRM and onboard cooling, no RGB, lacks Gen 5 NVMe
In theory a 2-slot DDR5 motherboard should clock faster,
but only Asus ROG Maximus offers 2 DDR5 slots in ATX.

Initial boot took awhile, presumably feeling up fans, DDR5, CPU and other hardware.
Motherboard debug LEDs iterated, but too quickly for me to decode.
BIOS FAN settings in Hardware Monitor see Fan control
CPU fan defaulted to Auto and around 790rpm; I switched it to PWM.
Back fan (SYS_FAN1) defaulted to DC and ~ 950 rpm, switched to smart
based on CPU temp
0% @34C, 8% @46C, 90% @70C 936rpm @ 39C
Antec fan controller (SYS_FAN6) defaulted to DC and ~ 1800rpm, switched to PWM and smart based on System.. around 15% still reports 1090rpm and louder than wanted...
Antec DC chamber fan (SYS_FAN4) switched to smart based on PCH

booted MemTest86 from a USB key
4/4 with 0 errors; CPU cooler not warm; motherboard extrusion presumably over system chip much warmer than others (e.g.VRM).
That warmer extrusion will be under GPU, fins on it would be good, but could not be tall...
Rebooted to BIOS, set XMP, restarted MemTest86
...then rebooted BIOS to give hard drive priority for Windows 10 install
first boot should skip uninitialized M.2 NVMe and boot Windows 10 installation media USB key,
subsequently booting from M.2 initialized by Windows 10 install; eventually updating to Win 11

MSI Z690 flash BIOS updates are fussy about USB thumb drives!
Reset BIOS options to default: clear CMOS(page 22)

A prompt to remove USB key after BIOS update would be nice, before rebooting...
I yanked out the USB key, to avoid booting AOMEI BackUpper.
