no. and thats jedec 6400 which is a bit slower, timings wise, than expo 6400.
As soon as people figured out that it actually has a good chance of working as advertised, and market prices adjusted to demand? It is the current capacity and practical performance ultimate for AM5 right now.
That same logic got us scalped GPUs. It sucks, for sure.
is MSI just as good on the intel side at handling high amounts of ram?
wondering whats the cheapest board you could get 192-256gb going.
A B850 tomahawk intel equivalent. basically.
Has anyone tested 2 x 48 or 2 x 64 GB DDR5 DIMMs on AM5 ? Is it stable on X670E/B850/x870e AM5 boards or is it a lottery ? Will they run at 6000 ?
I’m having an issue getting my 16gx4 (two kits) to work I currently have one set in A one in B. I’m aiming for 5800-6000, and I have a 7800x3d with aours x670e master.
I think it’s something to do with the termination values not the voltages. Here is a pic of my stable 2 dimm to get an idea about the Quality of the Ram. It’s A-die with a xmp for 7800.
Not usually achievable. You could try a coordinate descent search on the terminations and such and see if it goes anywhere. But FWIW my experience is it’s rare to find an improvement, much less one making the transition from unstable to stable, and most steps make things worse. Spending hours periodically bricking your board and flashing back is pretty normal.
Optimal terminations depend on package, socket, mobo, and DIMM PCB impedances as well as socket type and DRAM. So they’re more variable than timings and what works well is less likely to transfer between builds. That said, I’d probably start by seeing if lowering the processor drive impedances helps any.
Hard to tell with VDD and VDDQ both being reported as 0 V.
The people at AMD who actually know don’t seem to be saying, Doesn’t stop people who don’t know from posting claims that LLMs pick up and repeat. ¯\_(ツ)_/¯
Has anyone done actual testing to see if there are memory improvements. I would be hard to tell I guess between actual improvements and silicon lottery. You would need a large sample size to really know.
If people from AMD have said there are improvement then I would believe it, I just haven’t heard anyone say this personally.
I thought Wendell said something about a forum post with the proper terminations?
Which is why it wouldn’t surprise me if none of the memory teams at AMD, Corsair, G.Skill, V-Color, or Crucial actually know.
FWIW best luck I’ve had with an AM5 2DPC 2R overclock so far’s been on Raphael, though I suspect I’m more kit than IMC limited.
Managed to do 6000Mhz CL32 on the Aorus Master X670E somehow.
Basically used the same settings I used before on the MSI, like this
But CL32 instead of CL30, and RttWr RZQ (240).
Using latest BIOS from Sept. Using one from August doesn’t work. So I guess Gigabyte did something.

not long until all g.skill 256gb desktop kits go above 2000 usd.
Absolute bonkers, I got my 4x48GB kit for like 800USD past year. Now it is way more than that sadly.
Just had a look… My then-already-overpriced 2x2x64GB kits from June are up 100%, and my 2x48GB kit from less than three months ago is up 250%. It’s nuts.
It would be the single best rate of return I’ve made to date, if I get rid of them right now. Sheesh.
You’re telling me… I got one of the new 4x64gb cl34 gskill kits for $450 right before all this happened (employee price), and now I no longer have my job and I’m looking at a kit of RAM I could sell for $2000, like a week’s pay in profit.
I’ve never been a scalper before and I never intend to, but I got the devil sitting here under my desk tempting me
I also have two of the 2x64gb cl30 kits I’m not using either that are up like 200%, I feel like a RAM hoarder but I swear this wasn’t my intention
i dont know who’s paying that for desktop ram at this price point…
also maybe a would be buyer would prefer to buy from a vendor that offers a warranty.
you may be able to get more than what you paid but not quite 2000$
Sorry I misread your post where you said “not long” and my brain skipped over that and just saw the “2000 price point” part, my mistake
dont get me wrong, if you wait you might be able to sell that 256gb for 2000$ because it may very well go well beyond 2000$ , there’s no ceiling in sight for this pricing craze.
Hey I joined so I could add my 2 bits and get an opinion. I’m building a Gigabyte B850 AI TOP, 9950x, and 48x2 of Hynix HMCGY8MGBEB2B256N. Gigabyte QVL calls out KSM56E46BD8KM-48HM, which as far as I can tell, is the same memory, so I’m at a loss there. Swapped around, reseated cpu, etc. can post so tried bios update via qflash button. Not sure if it worked. Gonna pick up an 8GB stick for testing and looking through bios.
I haven’t gotten this to POST yet- just starts and the DRAM led stays lit.
I case anyone reads this later… ended up being a bad TPM hardware module. I can verify that the Hynix I used is working just fine

Just in case anyone searching and has found this thread wants to know about the Asrock X870E Nova, I’ve tested the newest beta bios 4.03.AS02 and I still haven’t been able to get past the 4800mhz I was stuck at with the previous 3.50 bios update, so if you’re hoping this was the asrock bios update that finally fixes it, unfortunately it isn’t.
So I’m just using an msi carbon wifi instead which it works perfectly in but yeah just wanted to update since I haven’t seen anyone else mention it and I do have hope for these boards with bios improvements.
