Best Current B die Bins for 3950x 3800mhz CL14

[harm9963]

For a $108.00 dollar's, open box at Micro Center, have to play with the bios for sure .

For counterpoint, I have finally got a stable system on X470 Taichi (which is *definitely* t-top) with 4x8Gb 3733 16-16-16-32 coupled CR1. DRAM @ 1.45v and SoC 1.1v. Nothing I have tried gets me to 3800.

I am running some top rated Team Group XTREEM 4133 18-18-18-38 underclocked to 3733, and feel comfortable eliminating the DRAM as the weak link.

I went back to the X570 Taichi today and decided to swap out the 3950X with a 3900X from another setup. I was able to boot and run at 3800C16 1:1 with the 2nd chip.

I booted first at 3733 and then tried 3800 with 2x8GB and again later with 4x8GB installed. I didn't have any of my previous... "No post/hang: code 07 issue" with the 3900X. 4x4GB did required more BIOS fine tuning/dialing in of settings then running just 2x8GB sticks.

3900X X570 Taichi @3800C16 ~1.42v DRAM: ~1.075v SOC... Quick 1 hr. AIDA64 mem/cache stress:

Running on the CH8H today... 3950X @3733C14 (4x8GB) ~1.44v DRAM and ~1.1v SOC running a quick 1hr. AIDA64 mem/cache stress.

I don't know for sure but I'm thinking now that 3800C14 (2x8GB) is probably going to take up towards ~1.5v DRAM provided that I'm lucky enough to have a kit spec'd with a level of "quality IC margin" that could do it? Then I'd need two more similar quality sticks to even attempt 4x4GB??

I just purchased 16GB Team Group Dark Pro (2x8GB) DDR4 3000 15.15.15 from www.overclockers.co.uk for £75, they are Samsung B-Die and I'm hoping for some 3600mhz C14-C16 on my lowly little Ryzen 1600 AF

On a 3950x with my b-die G.Skill 2x16GB 16-16-16-36 Neo 3600 RAM with a MSI X570 board on the old AGESA 1.0.0.5 BIOS (best for memory overclocking) I get the below TM5 and HCI MemTest stable which is pretty much unheard of.

Most fast b-die bins will run 3800 14-14-14 at around 1.45-1.5v. My current kit is a 2x16GB 4000 16-19-19 Gskill kit which does it with no fuss at 1.45v on a B550-A pro (though it struggles to get to the XMP, frequency wise that board with dual rank kits seems to tap out just short of 4000), my old 2x8 4000 19-19-19 patriot kit does it as well on that board. My daily X470 board is pretty crummy at memory so the RCDs end up settling at 15 no matter what kit at 3733.

My recommendation would be with 2x16GB kits, firstly 3200 14-14-14 kits for value, but otherwise the faster kits aren't terrible either.

Hi,
Last set I looked at was 4000c18 2x16gb kit and 1.4v

I think the original question was for a 3950x. I really doubt one will do 3800 14-14-14 2x16GB stress-tested stable.

3800 will depend on the IF, but 3800 14-14-14 at under 1.5v is not a challenge for most 3200 14-14-14 b-die kits I've seen. Like I mentioned above some boards (400 series, I've seen B450 tomahawks struggle with this as well) will not like RCDRD at 14 or lower at 3800, but given that a B550-A Pro does 3800 14-14-14 no fuss at all I strongly doubt most decent 500-series boards will have a problem with it.
