Another 9800 x3d mainboard thread

MoridinUK · Wednesday at 07:30

Sorry, I'm lost in options and a little frustrated, the prices seem so similar.

I don't want to spend more than £220 really and I want the board to support the following, in order of priority for me.

1) 9800 x3d (and potentially a small overclock)
2) 6000 cl30 ram 32 gb
3) MC PCI-e 5 x 1 (my current card is 6800 xt (and yeah I know will be the bottle neck on this cpu) but I probably wont update to a pci-e 5 card but nice to have the option
4) PCI-E 5 x16 (gpu) x1
5) Fast lan/wifi (really wifi is more useful but i don't think my router supports anything flash and as I'm stuck on 67mb internet speeds anything faster than 1gb lan seems a waste but would be nice to future proof)

I really want to avoid the pci lane sharing, I've no real idea how to read a spec to avoid them and unsure which mainboard come with M2 heat sinks! Want to avoid buying an MC with one just to find my GPU can't fit.

mATX or ATX is fine either way!

Am I making a mistake not caring for usb 4? I don't have much use for usb at the moment?

I'm thinking b850 tomahawk as it is on offer and brings me close to my budget costs, but I'm still not sure I wouldn't be better off with a b650 and saving some money. Any reason to avoid it? (Other than being on pre-order I wish I could ask for the order to be sent when it's all available!)

Anyone know what happens if I make an order and can't use the parts to check they work until the item on pre-order arrives?

I just want 1 m2 gen 5 and 1 pciex16 (4 or preferable 5) but it's so hard to know which steal from the gpu lane and which dont.

Why can't I filter on boards that have m.2 PCIe 5 slot! lol

I'm trying to figure out is this board gives me a PCIe 5 x16 slot and a M.2 PCIe5 x4 slot?

Thank you both!

So I think it's this:
My basket at OcUK:

1 x AMD Ryzen 7 9800X3D Eight Core 5.20GHz (Socket AM5) Processor - Retail (SKU: PRO-AMD-03517) = £479.99
1 x Corsair Vengeance 32GB EXPO (2X16GB) DDR5 PC5-48000C30 6000MHz Dual Channel (SKU: MEM-CRS-02786) = £89.99
1 x Crucial T700 1TB NVMe PCIe Gen5 M.2 Solid State Drive (CT1000T700SSD3) (SKU: HD-07C-CR) = £114.94

with either this:

[*] 1 x MSI MAG B850 TOMAHAWK MAX WIFI (AMD AM5) B850 ATX Motherboard (SKU: MOT-MSI-03993) = £235.00 And reuse my Bequiet dark rock pro 5
Or
[*] 1 x Asrock B850M Pro-A WiFi (Socket AM5) DDR5 mATX Motherboard (SKU: MOT-ASR-04010) = £145.00 And pick up an AIO like [*] 1 x Arctic Liquid Freezer III ARGB High Performance CPU Water Cooler - 360mm (SKU: COO-ARC-01992) = £89.98

Yes I have both a mATX case or an mid tower ATX it could go in! I feel the aio should really go in the atx case though...

My friend had a mainboard that seemed to come with a heat sink on the nvme, I didn't want to get the model with one, for fear it would be too tall and I could fit the gpu or something. I guess I'm worried for nothing?

So this one:
My basket at OcUK:

1 x Crucial T700 1TB NVMe PCIe Gen5 M.2 Solid State Drive with Heatsink (CT1000T700SSD5) (SKU: HD-07F-CR) = £122.99

Mobo manufacturers wouldn’t make a NVMe heatsink that hit the GPU.

That would be a major design flaw lol.

I expect not, so I need to buy a separate NVMe heatsink from the mobo manufacturer? I kinda hoped they came with the mainboard.

I clearly need to do more research, all I've seen are NVMe's coming with heatsinks on them, or not.

Right so the mainboard comes with a heatsink and warns about making sure any thridparty heat sink will fit without causing damage, not sure how to work that out. I've no idea how much space would be left between the gpu and the heatsink I intend to put on it. I guess I am better off with a bigger third party heatsink, especially if I'm using air cooling on the cpu as there will be a lot of hot air to move about?

MoridinUK · 2025-02-07T08:33:16+0000

And another silly mistake, the case says max cpu cooler hieght 160mm but my cpu height is actually 168mm how it fits happily in a mATX case but is too big for a midi ATX case I do not know but I'm now quite upset. So I think I will need the AIO.

A tall NVME heatsink can stop the Arctic liquid Freezer III fitting.

If you have to get a T700, get this one and use the motherboard cooling plate and you should be fine. The MSI is ok on the compatible list.

Is there a better choice than the T700?

What ATX case? The Freezer III radiator is massive.

This air cooler should be ok, have added RGB and non RGB.

My basket at OcUK:

1 x Thermalright Assassin Spirit 120 Evo ARGB CPU Cooler - 120mm (SKU: COO-TLR-02720) = £21.95

1 x Thermalright Assassin Spirit 120 Evo Dark CPU Cooler - 120 mm (SKU: COO-TLR-02667) = £19.99

Total: £45.94 (includes delivery: £3.99)

Sorry, i should have said if you have to get gen 5. Nothing wrong with the T700 (maybe T705)

I probably dont _have_ to have a gen 5 but... t500 saves me some cash but seems so very much slower not that I'd actually notice much really...
Thank you for the cooler options.

The case is a Lian li Lancool 215 OR a very old cosmos 300 full tower
