I have 4 x 16gb dimms 3200c16 although they are B-die Corsair Vengance RGB PRO - I can't seem to get them past 2800mhz =\, is there something im doing wrong

I'd try 32GB in the 2 dedicated slots as per your MOBo manual. Update your MOBO to latest BIOS. Download the latest AMD chipset drivers. 'should just be able to plug n play with XMP on latest x570 BIOS's. Try
32 GB working 1st.

Also didn't think the Corsair 3200c16's were Samsung B-Die?

yeah neither did i, Typhoon reports as such

I have the same and they really are b-die, but clearly not the best binned. I got mine to 3600 with loose timings on an x370 board but with two sticks for 32gb of ram. My challenge is getting 64gb of this ram stable at higher than 3200 on the trx40 platform.

Ah gutted thing is my ram doesn't even do xmp, is it my motherboard / CPU or ram that's likely to be the cause ? Cheers

3000mhz was the max I could do with 4x16GB Corsair Bdie on my 3700X and X570 Taichi.

The memory controller can't handle 4 dual rank DIMMs at high speed.

Thanks no worries, do you have the settings for bios? Just looking somewhere to start for 3000mhz even

It was ages ago unfortunately, I don't think I wrote them down, I gave up trying to run 4 modules in the end.

Gigabyte UD X570 is a 4 layer PCB .

More layers the better signal/memory path ways . Way ITX boards set records, high 8 layer PCB and 2 dimm slot design .

also IMC will also play its part. thats a lot of ram and sticks for it to handle. Not sure if setting IF to 2:1 might help increase speed . know its meant for above 3733hz but worth a try to see if you can push 3200hz

I managed 8 sticks of b-die at 3200 (64gb) on 1st gen. Needed quite a lot of soc voltage and manual messing about but it is doable. Must be doable on 3rd gen given all the upgrades and better imc, just gotta spend a lifetime finding the stable point.

Thanks orbital, is 4 layer PCB good or bad? Also sorry I'm a bit of a rookie where does the 2:1 setting appear in bios

Presumably Threadripper? Not quite the same. It works out to 4 sticks per chiplet, so standard dual rank dual channel setup. 64GB setup in OP is quad rank per channel.

4 layer is entry . Gigabyte/Aorus Xtreme is 8 layers and thats like £700. Pro to Master range is 6 layers. Even with that helping, your still down to the CPU memory controller

Ah I see yeah I suppose I'll try another motherboard first, bleh :/ thanks tho

which board would you recommend for around £200

I wouldn't think buying a new board is a guaranteed fix. The X570 Taichi is 6 layer and wont do 4x16GB.

Hi would a GAMING X asrock make any difference? apparently it supports topology styke ram

The Taichi was meant to be T Top and it wont run 4x16GB well. Although there were rumours that they switched production from T Top to daisy chain. I haven't checked my boards traces to know for sure.
