9800x3d max ram speeds?

what would be the max mhz ram speeds on the best motherboard for it atm.
-
with 4 dimms and with 2 dimms?

and how much performance you loose by going 4 dimms?

I currently have an x99 system with 8x16gb ddr4.
I kind of like to double the specs every new pc..
-
so 256gb ram.

as the old intel enthousiast x-platforn is kind of dead.. and treadripper is more of a modern xeon than a replacement for that old enthousiast series that used to sit in between servers and mainstream..

the days of 4 lanes for ram (and having 8 ramslots) in a gaming pc are kind of over.

was the 6950x at 1600 euro at least a 10% faster than the 500 euro mainsteam cpu
plus you did get stuff like usb 3.2, m.2 and ddr4 one or two generations before maibstream got it.
and you got more than double the lanes in the days of sli essential.

thats not today.

so the only way to get 256gb ram is by having 4x64gb now. (or at least 4x48gb as it remains to be seen if any 64gb modules are to be released at all as non ecc)

but well that does need all 4 ramslots as just using 2 would give me 96gb ram which is less than my old pc had and not acceptable..

so.. what is the neth fps loss by going 192gb (4x48gb) vs 96gb (2x48gb) and at what mhz could each of these kits be expected to run?

LEXAR just came out with DDR5 6000 CL26
I wonder how that would do.

Depends on subtimings, low primary timings is worthless if they sacrifice the subtimings for it

x99 with xeon has 4 memory channels
am5 has 2 memory channels

Do you know how many people I've talked to on Steam who thought they were getting Quad Channel because of using 4x slots... LOL nope that's still Dual Channel (A & B)

Quad Channel would offer 8x Slots; 4x for A and 4x for B

And something like AMD EPYC 9015 has 12 channels...
What is it? A RAM bank?

AMD EPYC = Servers

At least you finally got something right for a change.

If you're going to speak like that, don't speak at all.

Go away with your bully non-sense. Get a life.

I will comment whatever I feel like commenting and you can't stop me. You're not the boss of me.

Last time i looked in RAM related subject , It dont matter too much about 2 slot or 4 slot ram theres a minimum difference because all consumer motherboards hav 2 lanes for the CPUs. The only motherboard that has more lanes than 2 is the ones that use "THREADRIPPER CPUs".

you should look again.....DDR5 is in 4 stacks of 32 bit and not 2 stacks of 64bit like old DDR4 was.....running 4 sticks will not let you hit rated speeds in most cases.....2 sticks is the only way to hit speeds of 6000 or higher......

Octa core processor and $500 MSRP.
But it is the current competition against Xeon.

64gb modules
KVR64A52BD8-64 - cudimm 6400mhz (in sales)
CT64G64C52CU5 - cudimm 6400mhz
CT2K64G64C52CU5 - cudimm 6400mhz kit (2x64gb)

udimm - Crucial 64GB DDR5 5600MHz - CT64G56C46U5 (in sales)
udimm - Crucial Pro 64GB DDR5 5600MHz - CP64G56C46U5 (in sales)
udimm - Crucial 128GB Kit (2X 64GB) DDR5 5600MHz - CT2K64G56C46U5 (in sales)
udimm - Crucial Pro 128GB Kit (2x64GB) DDR5 5600MHz - CP2K64G56C46U5 (in sales)

max you can get with 4 dimms 4800-5200Mhz, and if you luck 5600mhz but no more
issue with cudimm on amd cpu 7000 series and mb x670e no POST at all even with latest bios update AGESA 1.2.0.3a Patch A. cudimm will be works on amd am5 only with bypass mode

A lot of people slot in 4 modules and their AM5 system drops to 3600.
It took me ages to get my 5200 rated 4 modules running stable at 4400 with the 9950x3d.

The whole numbers thing is to show who´s got the longest ePen,
all threads and numbers throwing about it are the proof

Sure, if one buys a board for 500 and modules for double the price, studies electric circuits and licks the stick chips,
then the grass gets greener ... and faster ... maybe
