Build advice, amd system

Mierin · January 6, 2024

Budget (including currency): No limit, but no need to throw money away. USD is fine.

Country: Norway

Games, programs or workloads that it will be used for: Whatever games I feel like, software development, Media server.

Other details: Already own:

7900xtx tuf oc

4x 18tb 3.5 hard drives

2x 8tb 2.5 ssd hdd

1x 2tb m.2 samsung 990 pro

1000w psu.

Arctic 360mm aio

So I'm looking to build a new machine around Amd 7000-series. Right now I have a 5800x/x470 combo. This build also includes a case, as my current one does not really have room for my drives.

What I'm looking for is some specific hardware advice. I'm leaning towards the 7950x cpu, but a 7800x3d would also cover my needs.

Motherbord: is x670 the way to go? I'm a blank on this, but need 6x sata ports and would like pcie5 (do i need it?). No overclocking ambitions. ATX prefered. Would like it to cost less than the cpu.

Ram:

Can someone tl;dr ddr5 memory? My current build has dual rank b-die cl14 memory, but I assume other things are important now. Would at least need 32gb, 64 if it not crazy expensive.

Case: Fractal design Meshify 2 covers my needs, as do the define 7. Any other good ones (mid tower) that I should look at? Would like to have 3x140mm intake front and aio top mounted.

Thank you for all advice!

Is the 5800X not cutting it for you?

Have you tried PBO and overclocking?

Why change the build if you have components that good? Are you having performance issues with what you are doing?
For a case, I would recommend the Fractal Design R5. Great case and lots of HDD cage space

3x140mm does not work in the R5, but there are 2x140mm and you can top mount a rad. I would go with either of the others if you insist on having the triple 140mm in the front

The 7950X3D also exists, which is like a hybrid of those two CPUs, though admittedly that chip ends up with some weird scheduling behavior on occasion. It might still be the best pick if you want to do software development at the same time.

Only reason I see to seek out X670 over B650 is that it's easier to find an X670 board with 6 SATA ports, and even then it might still be cheaper to just buy a B650 board and a $20 SATA HBA to get the remaining SATA ports. As for PCIe Gen 5, nothing really takes advantage of it currently outside of storage, and even then it's only a few specific workloads. I wouldn't really consider that.

If you do want a board, MSI's B650 lineup is pretty consistent about putting 6 SATA ports on their boards, so that's what I'd look at, though given that the X670-P Pro is usually about the same price of those B650 boards and is generally a bit better built, that's what I'd go for.

TL;DR: Get 2x32GB 6000 CL30 or 6000 CL32.

Slightly less TL;DR: 4DIMM setups barely work, so avoid them if at all possible. The current Samsung B die equivalent on DDR5 is Hynix based memory (there's currently three different revisions, each with their pros and cons, though they're all miles better than what everyone else is making), and the low CAS latency kits are where it's guaranteed to show up. Ryzen's memory controller has two performance modes, and 6000MT/s is where the better performance mode is so consider that a max speed unless you want to manually lower the speeds. Dual rank doesn't really matter with DDR5, though the 32GB sticks will be dual rank.

I have the Define r6 right now:) Love the case, did a quick mod to make room for 3x140mm front fans. The graphics card is too large to use the define cases in storage layout, thats why this change came about. The new define have room for hard drives in the shroud compartment.

I'm not really having performance issues, but I need more memory and a new case, so I'll throw an old graphics card and psu in the old pc and sell it to mostly cover the new hardware. Bad excuse for wanting new hardware:)

Thank you, exactly the kind of advice I was looking for!

I did read something about the 7950x3d scheduling issues, thats why I was thinking the x - should be plenty powerful either way, and I could use the true cores for work stuff.
