Combination advice

Hi, I'm looking to upgrade to a new system that I will mostly use for gaming, ableton and other music use. I have several options I'm considering. I keep reading conflicting information on the number of layers mattering so I have two X670 options and a B650, as I do like that the X670s have more M2 slots, I do like tinkering with RAM OCing and do plan to push it a bit. The options are:

CPU -7800X3D

with either

Mobo 1 - Asus X670E TUF Gaming Wifi
and
RAM - 2x16Gb 5600 CL46 Hynix CTCCD532G5600HC46DC01 (As per Buildzoid's video)

OR

Mobo 2 - Gigabyte X670 Gaming X AX
or
Mobo 3 - Gigabyte B650 Aorus Elite AX
and
RAM 1 - 2x16Gb 5600 CL46 Hynix CTCCD532G5600HC46DC01 (As per Buildzoid's video)
or
RAM 2 - 2x24Gb 6400 CL32 Hynix M Die F5-6400J3239F24GX2-RS5K

What would be the best setup for the value? I quite like the features of the Asus board but if I go down in price I can afford the 2x24 sticks, just don't know what's more worth it for the 7800X3D really. I don't really mind giving up an M2 slot and some USB connectivity if the B650 is enough for solid timings at say 6400 for either of the RAM sticks.

It depends what kind of pushing/OC you're thinking of, I guess, but since the X3D isn't very memory sensitive and is not at all power hungry, I wouldn't much care about getting a 6-layer board, or the memory speed. If you're planning on keeping it long-term and doing a few CPU upgrades, then it would make more sense. The X670E TUF does have PCI-E 5.0 graphics though, which neither Gigabyte board do.

Not going to do some very heavy OCing on it really, I have another system for that, it's more just for some quick fun and getting decent timings at around 6400 to 7000 whenever that becomes feasible with Ryzen 7, although I don't really wanna push much more than 1.5V through the sticks.

I do plan on keeping it long term, but the only upgrade I'd thought of is going for the 2x16 initially and getting 2x24 when they go down in price, but if the 6 layer board is not an issue I could just get the 2x24 at the start. Kept my old 9700K for 6 years, so don't really know about CPU upgradeability for AM5, reckon the 7800X3D will be enough for years.

AMD already released an update to make higher speeds than 6000/6200 possible, but I haven't seen much about it, since almost everyone still buys low latency 6000.

2x24GB DDR5-8000 on a Ryzen 9 7900X!

I know the burning problem was the SOC voltage, not the DRAM voltage, but that sounds like a lot of volts for an X3D

Ah yeah I had read about that, but thought it might not be super stable at low timings yet. If I wanted to upgrade to maybe the last of the AM5 CPUs in several years, with a possibilty for overclocking, would it be better to go with the Asus X670E then? Does having 2x16 vs 2x24 make that much of a difference to the 7800X3D if they're running at the same speed and timings?

Yeah I had seen that, but I'm not really gonna touch the CPU more than through PBO and Curve optimizer, not fussed about OCing the 7800X3D much more than trying to squeeze it a little bit for some extra performance. But yeah the 1.5 I mentioned was for VDIM, I'm not that crazy

On another note I do have an MSI X670E Meg ACE I got on auction for £250, sunk another £100 to repair the bent CPU pins but it's otherwise brand new, could always keep that instead of selling it to fund other components. Just seem like an overkill board for my needs, if I was getting a 7950X maybe.

I doubt PCI-E 5.0 graphics is going to make any meaningful difference in the lifetime of the board, but 1st gen AM4 boards are 5-6 years old, so who knows?

Sure, but since the memory controller is being overclocked too, you can't only overclock/overvolt the memory, though buildzoid's video(s) would tell you more about how much is necessary than I can.

I'd just use that one, is a high-end board with some premium features (like 10Gb LAN) and selling them on is always a risk that someone is going to damage the pins again.

I suspect not, since they're both single rank, but I don't know.

Yeah that's why I was considering the Gigabyte boards, not too fussed about PCIe5 on the X16 slots.

That's a good point, I can't remember from watching the videos a while back but I think to push 6200MTs you don't need to push IMC voltages too high.

Fair enough.

Yeah it's more that I could sell it on ebay with the certificate that it's been fixed and tested by a professional, and make an extra £200 on top of that could go towards getting the Asus board with the 2x24Gb instead of the cheaper boards. I don't really need any of the extra features on the ACE.

Guess in the end the layers don't matter then for the OCing I'm gonna do and I'll just get the Asus if it's not a bad price come next year and if I can't afford it I'll get the B650. Can always get the Asus with 2x16 and wait until the 2x24 are on offer.
