I tried applying VSoC 1.15v, VDDG 1.05v, VDDP 0.925v. Still doesn't boot.

I did try something I found online to enable LN2 mode under AMD overclocking, and then go back to set 1900 FCLK in bios, everything else auto including ram. It did boot into Windows after some struggle, but in Windows, the fabric clock was fluctuating at around 1200 FCLK only. Unfortunately the guy only mentioned good luck stabilising FCLK from there and nothing else  doh.gif

Maybe I'll just go back and play with 1867 (3733), it was spitting error at 3733 16-16-16-32 @ 1.42v, maybe I'll try bumping up the voltage little by little. Dram calculator suggested up to 1.48v  sweat.gif

Dont put vSoC at 1.15V. You put 1.1V also good enough already. You might need to up your VDDP to 1V . Dont use that LN2 mode.
In your BIOS, there is 1 option call UCLK DIV1 MODE, you set UCLK==MEMCLK .
FCLK put 1900Mhz. RAM set to 3800Mhz , but you need to loosen your timings or up your VDIMM. From my experience , if you wanna do CL14 at 3800Mhz with a Samsung B-die, you need 1.5VDIMM and enable GearDownMode. And TRCD I cannot make it fully stable at 14 neither, I can do 15 only for 100% stable.
I think you are overly conservative with your memory voltage.

Guys, need your help. I just bought G.Skill Trident Z Royal 3600MHz C18 16GB (2x8GB) kits (2 kits for a total of 32GB) and using it with Threadripper 2950x
Unfortunately I can never get it to run stable with the XMP profile, games always crashes

I don't OC my CPU as I'm not an overclocker just want to run everything at stock speed
Definitely not RAM issue because if I install it on my other system with Ryzen 2600X, everything runs just fine

The RAM kits: F4-3600C18D-16GTRG
https://www.gskill.com/product/165/299/1552...35V16GB-(2x8GB)

My motherboard is ASRock Fatal1ty X399 Professional Gaming running latest BIOS v3.80

Any advise? Do you think if I upgrade to 3950X with X570 motherboard it would run stable on the XMP Profile? Was originally saving my money for Ryzen 5000 + DDR5

That is Zen + for you. What do you expect Zen + to clock like Zen 2? No way. That is the Zen + memory controller limitation.
If it even boots at 3200Mhz , you should consider yourself lucky already. And you should have bought a 4 memory stick kit and it is guaranteed to work together. You buy 2 piece , 2 piece like that, sometimes they are not of the same silicon quality. Let me give you an example, I have 2 kits of 4400Mhz CL19 RAM, 1 pair of them can do 1.5V 3800Mhz CL14, another pair needs 1.54V to do the same clocks.

Which is why you got a honest thumbs up.
Mentioning its a review sample, being clear about what you do and why you do it.
Like that everyone can decide if it's worth looking into it and spending time, or not.

And one more thing regarding GN and your facebook post.
I'm well aware that their reviews are super detailed, and with all the money coming in at their side and the manpower they got this better be this way. Otherwise they wouldn't deserve all those subscribers.
But that doesn't change that anytime they get deeper into the matter (especially on overclocking) they do lots of mistakes themselves.
So last time I pointed out they didn't understand how Nvidia cards clock.
Another example.
https://www.youtube.com/watch?v=-UkGu6A-6sQ
They just now only discovered that 4 way memory interleaving exists.
And the way he talks they didn't get that either. Otherwise he would have tested 4x8 vs 2x16 and would have had an AHAAAAA event taking place.
So when I say "their reviews are fine for basic stuff" I don't mean that what they do is basic (you get spammed with tables that any1 not having studied statistics must get annoyed by from time to time) but that anytime they go deep they do mistakes, just like we all do.
So now ... because of this review ppl will think wow +10% performance, lets go and buy 4x8GB kits. Which is exactly the wrong conclusion.

That 4 way interleaving even i myself get some very confusing results. I did a benchmark with 4 DIMM and 2 DIMM 8GB sticks. Same timings. I lost some read speed, but gain some copy speed if i go from 2 DIMM to 4 DIMM. I thought I'm supposed to see improvements on both read and copy. shocking.gif

Hi any sifu can recommend me some cheap ram that can be overclocked slightly?
Is there a way to get these samsung micron die in Malaysia?

edit: For ryzen 5 series, looking at 8gb x2, not interested in rgb and bling bling just pure performance thanks

If you are willing to take a gamble, actually you can get very good binned Samsung B die for around RM600+ brand new for 8GB X 2 , you must have Paypal account though.
Here

It takes about a week to deliver to your house. If you pay RM600+ in Shopee, you get Hynix DJR only.

But this kit is not " just set XMP and thats it ". You have to set alot of timings manually. However, it is a Samsung B die, so they all have roughly the same characteristics.

I have 4 sticks of these running over a year already.

I only have Zen 2, so that's the best timings I can do for my daily rig.
