Samsung B-Die trying for 4000mhz

[oobymach]

As title says I'm trying to get a kit of B-Dies to run at 4000mhz, currently have them p95ing happily at 3800 but every attempt so far at 4000 has workers failing instantly in p95 so I'm hoping the community can provide some zentimings grabs for 4000mhz on a 16gb kit so I can compare voltages etc. and try and figure out why I can't get them to 4000.

The kit in question is a 4400mhz kit (pvs416g440c9k) so 4000 should be doable, also I had my 32gb kit running at 4000mhz (its max speed) with 2000fclk p95 stable before swapping kits so I know it can be done.

Try these... my Samsung B-die kit can do CL16 4000Mhz with 1.45v. My 5600X can do 2000 Mhz FCLK and a 1:1 with my memory. Your timings might work with 1.45v.

Note: These are not my timings.

Just stumbled across this one in the Aida 64 thread, plugged in the settings and it's p95 stable so far, hasn't failed any workers doing its thing in the background.

I would try bumping VSOC to 1.15-1.1675, and VDDG IOD to 1.065. With those timings maybe VDIMM to 1.45-1.475v unless that is stock

Edit:

NVM!

Ah you have that patriot 4400 kit. I have 2 of those. One kit needs 1.5v to run at xmp 4400, the other can only do 3800 CL14 with 1.5v. I consider them trash b-die. But hey they were under $100 back when b-die was all the rage and tripple the price for exact same bin from other brands.

Anyways since your at stock timings / voltage and going down in frequency, you shouldn't have to worry about the ram being unstable. I would raise the IOD voltage slightly and see if that helps. Maybe to 1.15v

 

[oobymach]

Yeah got them stable at 4000, here's the zentimings grab. I lowered vddp as it was almost 1.2v on auto but the rest are all on auto. TRFC 280 is as low as I can go error free at this speed, but 280 seems just fine.

I can't recall what I paid but the kit failed after a year or 2 and I just swapped them for a 32gb kit I had and forgot about them for like a year or more before I got around to RMA.

You haz one for me? So kind my address is...

These are my timings...

To all...

While you're on those speeds check frequently for WHEA (errors) with windows event viewer

...or with HWiNFO sensors

I am so jealous of you lot with your 4000mt's. Especially at 16 - 15 timings

Why man? Because of the higher benchmark scores or because of the +2% in framerate?

You all have fun and try not clinging into numbers too much

You have a good point but

You know what it's like to want better. Makes you sick.

I've gotten some pretty nasty speeds out of my B-Die, 4300 by running C19. The way my motherboard has been lately, I don't know that I'd bother to replicate this but I was able to get a pretty DDR4 overclock frequency a few years back when I first built it:

Intel Core i5 8600K @ 4801.15 MHz - CPU-Z VALIDATOR

[qpyumu] Validated Dump by Vario (2018-01-19 22:05:35) - MB: ASRock Z370 Taichi - RAM: 16384 MB

valid.x86.fr

from my notes I got this with 1.35V vdimm but it wasn't really stable.

I have the G.Skill 2x8GB 3200C14 TridentZ

Oh yeah they are good fun

That TRFC can't be right!

Oh look, thousands of hardware errors, guess that means it's not entirely stable.

 

[freeagent]

VDIMM?

1.6ish?

Toight

That's bonkers...

The WHEA errors are probably nothing to do with your RAM but the Ryzen CPU IMC. If it does not crash or act weird i would just ignore it if
its WHEA 19. If it does bother you then run 3800MT with 1900 FCLK it should not throw any WHEA errors on most ZEN 3 CPUs.

Else try increasing VSOC and IOD and see if that helps to stop the WHEA 19 errors.

Event ID 19 are warnings (as it said), not errors. But you're on the edge of it... You can see that those are coming 3-4+times/sec
Its really your call if you want to stay there or or back down a step or 2.

And you can create a custom view for WHEA in the event viewer

Nah, 1.6v is a good starting place on B-Die with tight timings and 4000mhz clocks. I run mine CL14-14-14-34 around 1.60v. Well I did when I was using a ddr4 system any ways.

I hope to soon join into DDR5 threads. Samsung has ddr5 B-die kits. Unfortunately I cannot confirm mine with Thaiphoon Burner cause it's not updated for ddr5 yet. And I'm too lazy to pull the spreaders, but cpu-z says samsung.

Sorry I've got this...

Corsair with SK Hynix. They scale best with loose timings and high frequency.

Have a set of cheap CHEAP PNY 2667mhz (XMP profile actually) that I was able to pull 3800mhz from.

Not sure if you saw the thread over at LTT, but I'll drop a link so you can browse it.

Memory overclock *The 70$ PNY 2666 kit

This thread is designed to help with overclocking on budget memory modules. (At your own Risk!!!) You know, the memory kits that Thaiphoon burner doesn't seem to read? (I'll show you here how to get the information. Be it complete or not....) But just to let you know, this will be a fresh start O...

I was on 3800 and they're Micron B die. I'm going to put it back on 3800 as I had the TRFC incorrect.
