Please, calling all memory experts for some help. I would like to run 4 modules on my X870E Godlike. Is it possible, are there any ? I know it depends on the IMC and the CPU infinity fabric and the memory controller and silicon lottery. I also understand some RAM are single sided not dual sided. But here in this video, Game Tech Reviews he demonstrates this kit G.SKILL Trident Z Neo RGB Series (AMD Expo) DDR5 RAM 48GB (2X24GB) 6400MT/s CL32-39-39-102 1.35V. However i don't need 96GB. Maybe two kits of a 2X16GB and CL26 timings if it's possible. The kit he uses on MSI Memory compatibility says its single not dual. So can anyone help me find some ?

pairing memory from different kit can be a bad idea, ddr5 doesn't work well with 4 dimm, better just stick with 2 or take your chance.
Easiest way is to check QVL but i guess CPU IMC quality really matters.

Why?


That 2x24GB DDR5-6400 will work for sure with a Ryzen 9XXX CPU.
But not 2 kits of that!!!
2 x 2 kits is not the same thing with a factory matched kit of 4.
Did you read carefully the "About this item" section?
G.SKILL is saying the same thing:
Do not mix memory kits. Memory kits are sold in matched kits that are designed to run together as a set. Mixing memory kits will result in stability issues or system failure.

A piece of advice: stay away from 4 x DDR5 modules!
Acheive the amount of memory you need with 2 modules only.

Don't worry I skipped the idea already. It's already a passed thought. I ordered the QVL ones I found on amazon. Just one set of 2X16GB(F5-6000J2636H16GX2-TR5NG) Then run them in Dual channel mode
Slot 1 and 3 ? I mentioned this in my build thread that I cancelled those original kit seen in the video for these Royal Neo ones with Expo.:)

DDR5-6000 is the best choice for the current AMD CPUs. :biggthumbsup:
Why?
Because around 6400 most of the AMD CPUs switch to Gear 2 (a 1:2 divider is introduced at the IMC level).
And DDR5-6000 in Gear 1 is much faster than DDR5-6400 in Gear 2.

For 2 modules use the Slots 2 and 4 (counted from CPU).
Double check the manual to be sure about the numbering.

Ah the reason why I said 1 and 4 maybe I'm confused. Didn't the old Nvidia 690 and 790 chipset dual channel work that way ? Slot 1 and and 3 or was it always 2 and and 4 ? I used to have a striker Extreme then a Striker II Extreme with a Core 2 Duo Quad Q6600 G0.

Before that I had Abit boards I don't remember the models anymore. Before my current Z490 Godlike I had a Asus II Gene with a 9700K. I went a lot of years without building and using custom PC's. I really don't remember what I used or did in between those years. I have a bad memory and my recent diagnosis for Autism and learning disability hinders my memory with certain past history's. Sorry to babble on.

About the AM5 architecture. I'm learning slowly. Coming from Intel. I did realise that the 6000 is the sweet spot for Overclocking from the baseline JEDEC spec of 4800 or 5600. So I should be able to run a 1:1 ratio hopefully with the correct RAM. Thanks RemusM :)

Yes you can run 1:1 6000 MT/s it work on 2x24, 2x 32 and even 2x48 GB kits in 99% cases, but you still have small chance of some issues.

As slots goes you have A1,A2,B1,B2 where A and B are wired together and reason for using SLOT 2 and 4 is that those are further away from CPU and are better to be ones that are connected as it reduce some interference.
Also latency CL26 vs 28 or even 30 does not make that much difference its where tRC values are getting more impact than CAS latency.

Another problem you will have to work with on those fast CL26 memory modules is voltage and also to it connected voltages.
Example from GSKILL 48GB kits, CL26 use 1.45V which is bit too high, 1.35V is safer and create a lot less heat. Similar its with capacities, 24 and 48GB modules use less voltage than older 16/32GB ones.

And please make sure your memory stays cool, in normal operations its not that big deal but if you load something with heavy load in memory its memory goes high.

Check here nearly 80 degrees after 10 minute memory test in OCCT and it would have even go higherIf i didnt catch it and added fan.
Try to keep memory under 60 as going higher it can create errors and affect stability, And BT when I tried strictier setting power went from 6W to 9W which would further increase memory temps @1.35V, I dont even want to know how it would be with 1.45.

Thanks for telling me all this but its too late. I already bought the memory. I've already canceled one set, before buying this other on Amazon. It's useful information. However are those SKUS still available to buy anyway ? or EOL ? Well you have Sir, the exact parts i'm looking to buy for PC. Although according to TomsHardware my Case is virtually the best cooling platform for CPU idle, CPU Load, GPU idle and GPU Load. It's at the top of the cooling charts.

I'll be using custom fans for the Arctic AIO, and CoolerMasters better fans over the standard ones. I'll have as much cooling in the case as possible hopefully for positive pressure and not negative. You can't exactly buy coolers for GSKILL because the aesthetic design would be pointless. Thankyou for showing me your temps though and for warning me giving me a heads up.

Are those 1.35V KIT SKU's still available in EU or Uk ? UK being where i reside. Also i was planning to buy a Seasonic PSU but wasn't sure which wattage i needed for upgrading to a 7900XTX or a 9700XT. So i should be ok with upgrading to similar model you have. My PSU is 850W Rog Thor. I aren't sure yet but i may be getting a AIO version of the GPU for the first time. I've never an AIO cooled GPU before. My current GPU is a AMD Sapphire Nitro+ Radeon 6900 XT SE OC. After all it's a dream PC and i'm going all out. Thanks

You see the top middle Gold one. I managed to get one. LDLC have it in stock. This one. The 1.35V one.

Yeah, I am using same memory just 96GB and silver.

I don't know why I missed these. I had my heart bent on 2X16GB and 32GB. I completely missed out on the fact that these ones were lower voltage skimming over the researching the page. And I was thinking also the memory would be EOL and harder to get hold of. Anyway I bet it's lovely. I hope your happy with yours. 48GB is more than enough for me as a Gaming Computer. It's a bonus on top of the lower voltage and lower temperatures I'll be getting over the other ones. They are still on order and I don't think I can cancel them from Amazon. But I'll use them as a back up in another system at some point in the future.

Chips for 24GB and 48GB modules are newer, probably even updated design on updated process.
Just one warning, they are much brighter than other modules.

Amazon cancelled the second kit I ordered. They really are going to love me lol. The 1.45V one. So I await a third kit. Not from Amazon. Sorry Amazon. But I did get the Coolermaster case from Amazon. This kit is coming from LDLC. If they are brighter, can we turn down the brightness in the MSI software ? or GSKILLs own software ? Also today my Arctic Liquid Freezer III 420 arrived. 😁

Kind of, you cant for multicolour effect, but you can set value 0-255 for each of RGB for static and single colour effects using MSI Mystic light. And I would say non intrusive intensity is about 50, but I am probably just turn it off,

Nope, zero issues, no problem with DD3, memory, nvme speeds or PCIE gen.
I heard once USB disconnect around 4th day using board, but now 3 weeks later its still all working.
Do you know what date the board is by looking at the box ? I'm not sure whether that makes a difference to getting one without problems. I haven't read the X870E Godlike Thread all the way through. It won't be getting built for some time. I'm waiting on buying the rest of the parts and for more Seasonic PSU supplier stock.

People are still having issues. But have we got a more mature newer revision, IDK. Mine is still in the box in wrapper, it won't be getting built for some time. I'm waiting on Seasonic PSU stock. I also can't decide on GPU. 9070 XT XFX Mercury MaG Air OC or the Sapphire Nitro+, or whether to go for the Sapphire 7900 XTX Nitro+. I have a LG OLED E9 55" as my computer monitor. So I either play in 1440P or 4K.
if you look at barcodes on box cover, there is EAN and next under mention month, for me it says JAN.
