is this B-die?

[TheLostSwede]

RTC not supported for this gen CPUs.

Ryzen Master?

 

[Svop]

Just get the Ballistix, or get something a little faster. There is no need for 4000 mhz ddr4 on the intel platform.

Their price is almost equal. ($ 7 difference). The question is which memory is better for the intel system?

Ryzen Master?

Here it is.

 

[TheLostSwede]

Here it is.

You're off coupled mode, so you're going to get hit in latency sensitive applications.
See if you can increase the fabric clock to 1900MHz.

Why nobody try to update and use last version of thaphoon burner?

It doesnt work at 1900 Mhz. Also, afaik, as my RAM is running at 4000 MT/s. it can overcome latency bottleneck caused by IF.

can you send such a screenshot from Aida?

Hey guys
I found this topic here while I was doing some searching about my new Kit ( G.Skill F4-4000C18D-16GVK ) and I wanna share my experience with you.
First this kit has a D die ( not a M die).
Dram calculater doesn't support it.
with this spped und Timings: 3733 (FCLK 1866) 16-20-20-32-CR1 I've got good results. ( I used the Timings for a C die I found it hier)

first pic: XMP
second pic: only Memors speed und FCLK adjusted
third pic: botth speed und timings adjusted

 

[TheLostSwede]

Here You go.

Still uncoupled, you need to set the Infinity Fabric to 1996MHz well, right now it's 998MHz as you can see by the Northbridge clock.
Ryzen Master also says Coupled Mode OFF. That should read ON.

FCLK dont go over 1800 no matter how hard I try. thats why its not coupled. Its running at 1800.

Then you are much better off running your ram @3600MT (with lower timings) and not @4000MT like you are now. You will get much better performance, especially the latency.

So far I have failed with any tweaking except XMP...even tried at 3200...but system fails to boot. Now @aljanadi.o has posted an update and timing, I will try to run at that timing OR near of that timing.

 

[heky]

You can try leaving the xmp on and just manually changing the IF and Memory clock to 1800.

 

[TheLostSwede]

FCLK dont go over 1800 no matter how hard I try. thats why its not coupled. Its running at 1800.

But FCLK isn't IF clock. You need to chance the Infinity Fabric clock, it's most likely done elsewhere in your UEFI.
And I had a bit of a brainfart, which someone else pointed out above.
You should aim for 3600MHz (1800MHz DDR) for the RAM, 1800MHz FCLK (which you say works) and 1800MHz IF clock.
You know you can enable coupled mode in Ryzen Master, right? You can make changes to the settings there.

You can try leaving the xmp on and just manually changing the IF and Memory clock to 1800.

That doesn't work well on Ryzen 3000. The XMP settings will most likely prevent the system from booting as well, if he plays with the other settings.

 

[heky]

Thats why i said "try"...It really doesnt make sense that the board would boot with 2000MTs but not with 1800MTs if he uses the same timings.

I also suggested to him already to manually set the FCLK and the IF speeds...

@amit_talkin this timings were for cjr die, they worked for my djr die but with an single error , so now I‘m back to xmp timings with just adjusting the memory speed and fclk till i get rid of this single error.
here is the timings I used

Why not tune your settings instead?
Try increasing the Trfc a bit, that should fix the memory error.
This is better than using some random table from a website.

@TheLostSwede I don't have the Patience for it but I'm trying anyway und here it is

While randomly tweaking I‘ve got a very good result (for a kit under 100€), but it was only for one time und with errors. But I guess it shows that this kit has a very good ability fot tweaking
(Im not sure if it was just a bug!!!)

Looks like you solved the problem, as you got IF going at the same speed as the memory.
If you're getting errors, dial back the Trfc and the main memory timings a bit, maybe try CAS17? Odd CAS timings can be a bit funny with Ryzen though.

 

[aljanadi.o]

here are the timings I use now:
16 19 19 32 55 440
subtimings: tRRDS 4, tRRDL 6, tFAW 16, tWR 16, tWTRS 4, tWTRL 12, tRTP 12, tCWL 16, tRDRDSCL 4, tWRWRSCL 4
all the other timings were left on auto
voltage: RAM: 1,4, Soc: 1,1, CPU: 1,275 ( CPU OC: CCX0: 4,3, CCX1: 4,4)

read: 53800 to 54000 mb/s, latency: 65,3-65,9 ns

SOTTR, BF 5 and Fortnite are working perfectly ( these games have always caused probelms by OC on my PC)

 

[noise36]

I just signed up to say that while Ryzen DRAM calculator works for this ram but that I found the settings unstable and the process confusing and ultimately a waste of time.

So what I did in the end was run it at stock 4000mhz settings and stock voltage 1.35v and down clock it at 3800Mhz with 1900mhz IF and its fully stable and has significantly better speeds and latency than running at 4000mhz.

Basically had it working in just a few clicks in the MSI B550 tomahawk bios by just selecting the 3800mhz "oveclock" and manually lowering the voltage... set and forget! I am sure I could lower the timings but cant be bothered really.

took a screen shot of taiphoon burner with my B-Die for referance... Interesting the hynix stuff is 25nm not 20nm...

 

[voronin.py]

Sorry for bumping old thread, but I have some new information about this ram. So I found a local guy selling it and I asked him to send a screenshots from Thaiphoon Burner and couple of other photos, and guess what, its says that its Samsung B-die, really confusing yeah? My guess is that some batches did come with Samsung B-dies eventually. But is that common for G.Skill to change die's for existing models?

 

[Bones]

It's not unusual for any maker to change IC's period.
They all do it depending on what IC's are available to use in production at that time of manufacture, usually reflected as a different revision of the model/series.

G. Skill at least is good about having info about whats in the sticks with the numbers on the data label, you just have to know how to interprit the info it has.
