I think now I'm going to order the msi tomahawk x870 wifi with some gskill 6000 cas 30. I thought about getting 6400 but I'm coming across info on the web saying it's a crapshoot and 6000 is good enough while almost guaranteed to work.

I can't guarantee that every CPU can make that, but every ASRock X870/X870E and Gigabyte X870E I tested could make 6400 1:1 stable and post at 6600 1:1 on my pretty average 7950X. Also ASUS X670E/B650E and Gigabyte B650E. 9 or 10 mobos in total. Only Biostar couldn't make it. On the other hand, every 6000 CL30 kit that you buy should easily make 6400 CL30/32.
 
I don't doubt that these GPUs will be speced for 500W to 600W usage. My bet is that they are rated for higher power draw. One of the biggest issues with the 4090 is that it kept exceeding the 600W power connector limits (among other connector issues). The obvious way to stop having power connector issues is to upgrade the connector. Since that standard is locked in, I'm guessing Nvidia will have 2x 12vHPWR for the 5090. 5080 and 5070 will use 1x 12vHPWR.

However, the PSU releases are not confirming my theory. We would probably see more PSUs out right now for the 5090 / AI systems (multiple 5070s or 5080s, etc) where the consumer would need multiple 12vHPWRs. CES2025 will either prove I'm right or wrong.
Not smoking what you're passing, sorry. We wont need to wait until then. :)

All the rumors show more power, but around the 500-600W mark. I don't think there are many systems around that can support 8x PCIe connectors as you said.
EDIT: Or two 12VHPWR

Thanks. Once I get everything together and tested stable I'll try pumping the ram to see if it gives me any extra fps.

I went with this gskill flare x from the gskill compatibility list for this mobo. I like the low profile and all black,

G.SKILL Flare X5 32GB (2 x 16GB) 288-Pin PC RAM DDR5 6000 (PC5 48000) Desktop Memory Model F5-6000J3038F16GX2-FX5​

 
I wish the 6400 CL30 kits came in non-RGB. :(

@ed
I had not seen that information before. Too bad Nvidia isn't going to do that, hopefully they have figured out how to make sure the plug will always socket in correctly.

You can always turn it off or set it to dimmed white that looks more professional than any rainbow or blinking mode :)
6400 CL32 is more popular, and brands like Kingston sell them with or without RGB. The performance is about the same as that of CL30, and if you want, you can set CL30 on CL32 kits. I only noticed that some motherboards dislike CL30 at 6400. In other cases, you may need to set a higher voltage, which is probably why most brands avoid it.
I reviewed all X870/X870E motherboards with Kingston Renegade 2x48GB 6400 CL32, and it works great at XMP (all leading mobo brands support XMP and EXPO). 2x32GB and 2x48GB kits are dual-rank, so they will be slightly faster in some tasks. I'm not sure if it matters much to you.
 
I was hoping to drop the CL to 28 if at all possible. Keep RAM latency at its lowest. We'll see though. I'll be happy with 30/32 just from profiles.

You can try it, but it may require 1.55V VDD, so it also needs additional cooling for stability. Once you get everything, just check how can you set it and compare different settings. I can only tell you that on AMD it's not worth pushing CL as many applications run not much worse even at CL40+.
 
AM5 sockets stamped with "41P1" may have a plastic molding issue that causes the CPUs to mis-seat. Some motherboards without the issue have sockets stamped "41R1".
Have to wonder if this socket revision was only used recently. I don't think I took photos of the open socket when building my current system and I'm not about to dismantle it to check. Hopefully a system that has been running near flawlessly for over 6 months is unaffected, and we haven't heard of this until now suggesting it might be something recent.

Agree... feels like it's a more recent thing... so you wonder X870/X870E only? Never caught if it crossed chipsets yet.

It's funny, I saw wccftech posted an article about this but had no idea and was guessing along the lines of too much voltage, LOL.
 
I wonder if it's a socket issue or if someone put too much pressure on it or installed something wrong and tried to blame the design. It's the first time I've heard about it, and the socket looks mechanically damaged in multiple places on all photos in the link.
The first photo in the link looks like someone installed the CPU incorrectly, pushed it into the socket trying to close it, and then installed it again. There is a crack from the top. It just doesn't look like any molding issue. I'm not saying there is no socket issue, but are there photos of this issue from before CPU installation? If it's a global issue, then for sure, many people checked and found it on new motherboards.

Edit:
I just checked photos from my reviews, and every X870/X870E mobo that I reviewed (ASRock, Biostar, and Gigabyte) has a Lotes socket, except for X870E Taichi and Nova - Nova has 46W1, and Taichi has 44S1. All sockets on my mobos look fine (even if I don't use socket photos in reviews, then I always take them just in case).
I had no ASUS or MSI mobo from the new series.

Looks behind me....light turns on that I have literally 2 dozen x870/x670 boards there. I'll report back.... eventually. Ha.

This is the same for me... havent checked X670, but, I highly doubt those have the problem.

I still stand behind 600W+ for modded 5090s.
I've highlighted the new/keyword there. Modded ones, sure. Stock, TGP/TBP won't be over 600.

I thought I posted that here as I read it yesterday... still one connector, but now confirmed. ;)
 
Yeah the one connector is a big issue. I've got some resources, I'll switch the GPU HP12V out for enterprise version and then use 4x PCIe 8pin to get 1000W input ;)

I'll bite... what's the 'enterprise version' (link) and how does it differ from the new connector?

Also, how do you plan on getting 1KW from it when 4x 6+2 = 600W (675W with slot power).
 
The graphics card power limit won't let you go even close to the max connector power, not to mention above it. If you find a way, then you can connect 4+ connectors, but the card still won't even reach the limit of one unless you make some OCP/OVP hard mods. Even then, modern cards have a voltage limit, so to push the power above the stock limit, you need hard mods to unlock the voltage.
Nvidia protects itself from RMAs, and graphics card manufacturers protect themselves too. There are no fully unlocked graphics cards anymore.
 
I got everything together last night but for some reason the system keeps hanging at the very end of the win11 installation after it installs updates and resets a few times automatically.

It seems like it's doing a final reset and booting into windows but then the spinning circle under the msi mag logo freezes and nothing ever happens even if I leave for an hour. Tried to reinstall twice and same exact thing every time.

I guess I'll flash the bios and do a memtest boot disc next. The ssd tests good on the motherboards built in bios test and the ram is recommended for this motherboard by gskill. The windows 11 .iso was downloaded yesterday and put burned on a fresh bluray.
