Motherboard advice

[Wraithsiege]

Got my hands on 9800X3D. Which motherhoard should I pair it with.

Asus ROG Strix B650E-F
Asus Tuf Gaming X870 Plus
MSI Tomahawk X670E
Gigabyte Gaming X WiFi 7 X870
Asus Prime X870-P

These are couple of boards i could find in my price range.

Which one of these is the best and which one should I avoid. Any other suggestions. I don't plan to OC

[ˢᵈˣ FatCat]

Asus ROG strix

either 2nd or 4th
avoid B motherboards or prime

count the vrm phases and make sure all vrm mosfets have heatsinks
cpu cores + igpu + imc

Asus ROG Strix B650E-F = 12 + 2 with cooling (probably 12+1+1)
Asus Tuf Gaming X870 Plus = 16 + 2 + 1 with cooling
MSI MAG X670E TOMAHAWK WIFI = 14 + 2 + 1 with cooling
Gigabyte Gaming X WiFi 7 X870 = 16 + 2 + 2 with cooling
Asus Prime X870-P = 14 + 2 + 1 with cooling

16 with cooling x ~25w per = ~400w to cpu cores

Asus ROG strix

pick a specific board, there are many asus rog strix boards
and 'gaming' is just a buzzword for crap

Come on phase? What you gonna do with phase where 8pin already enough
And he said no OC

thats how the power is converted from 12v to 1.x v to power the cpu
any cheap board can have 2x 4+4 eps connectors, and it makes no difference

the spec for each eps 4+4 connector is ~336w
and the vrms are not 100% efficient, loss is converted to heat

1x 4+4 is enough for most, but some boards have 3x 4+4 which is overkill unless the board is also powering the pci-e slots through them instead of the main 24pin atx

Either way, he said no OC, which mean all those are junk for him, he needs utility, which usually ROg. Never fail

[Phénomènes Mystiques]

I will pick, Asus Tuf Gaming X870 Plus WiFi.

Should check buildzoid's recommendations. Manually tuning memory is important with DDR5 and many boards just can't handle fast RAM.

OP said no OC what usually means that EXPO OC is max he will ever do. DDR5 6000 CL30 most likely.

I plan to go with 6400MT/s 2X32GB and two gen 4 SSD, 500gb one for OS and programs and 2TB one for games. Most likely evo 990

then any board will be fine

amd only guarantees its imc to DDR5 5600
anything higher is overclocking the imc on the cpu

ymmv beyond that
4 dimms is highly unlikely to hit 6400+

2 dimms should work, just enable xmp in bios to the 6400 profile to set the freq, timings and voltage to the dimms

Asus ROG Strix B650E-F = 2x6 + 2 +1 80A with cooling
Asus Tuf Gaming X870 Plus = 2x8 + 2 + 1 80A with cooling
MSI MAG X670E TOMAHAWK WIFI = 2x7 + 2 + 1 80A with cooling
Gigabyte Gaming X WiFi 7 X870 = 2x8 + 2 + 2 55A with cooling
Asus Prime X870-P = 2x7 + 2 + 1 80A with cooling

16 with cooling x ~25w per = ~400w to cpu cores

How does one calculate the W from A?

What kind of utility?
X870 boards are basically renamed B650 boards. I would go with B650E-E(if you dont mind intel lan) B650E Taichi Lite if you have money, X670E Steel Legend or Prime X670E-Pro if you need m.2, B650M-HDV/M.2 or I dont know maybe B650 Tomahawk if you are on budget.

core voltage is known, ~1.2v,
but the choke coils on mobos are pretty much all limited to 25a at 1v = 25w
at 1.2v = 30w, but some loss during conversion, so call it 25w to be safe

asus is not worth buying.....they will not give you any real warranty support.....i RMAed a motherboard only to have 6 broken ones sent as "replacements".....1 board fried 2 GPU's......

NEVER BUY ASUS they could never be trusted

I am aware that there is a solid chance that it wont post when set to 6400MT/s but im willing to take the risk. As far as i know, price difference between 5600 and 6400 is lot smaller than 6400 and 8000. I am going to buy RAM that is on QVL list for the motherboard. Does buying QVL memory increase chance that it will work on that speed or does it only represent that this specific kit was tested on the motherboard. At the end, the only thing left to do when i buy and setup everything is to pray to silicon lottery gods when enabling EXPO. I looked at X870 gaming wifi 7 board and i really like that it uses screwless mounts on ssd and ssd heatsinks. I will check the other boards soon.
