Nice, have you had any luck ocing them? Do you know what ics those are by chance?

This is mine from today with stock timings on memory clocked at 1900 instead of the stock 1800.
Dang, that Corsair Vengeance 3600 is a mean kit.
Ryzen 3800X w/ Noctua D15 and Crucial Balistix Sport AT 3200 TUF edition (micron e-die) @ 3600 w/ 1800 Fclk on ASUS TUF X570 (non wifi) not sure why the board always wants to clock the cpu 25mhz below stock? weak.
used timings from Ryzen DRAM calculator but they are the slowest ones so I still have some more tweaking to do when i get time.
16-19-19-38 1t
51,400 Read / 28,799 Write / 51,583 Copy
edit: just bumped it up to 3666/1833 and now i'm sitting at 52,133 / 29,332 / 52,393 still seems slow compared to everyone else. oh well.

yeah, was just going by DRAM Calc 1.7.3 thought it sounded high too because i've never had to enter a value that high before but i'm new to DDR4 OC'ing. do you think that's what's holding things back? found out the hard way this morning it can't go but so low. tried something in the mid 300's and it wouldn't post. had to clear cmos and start over. just went back to what i had before. may try and mess with it again later but with a smaller jump. but even if i change the speed down to like 3200 in the calc it doesn't go down but so much. any suggestions? also i found this chart if it helps anyone.561 trfc..
d3athf1sh Have you played with these settings yet?

The termination / cad_bus block settings do have a significant impact on ram stability at high(er) clock rates.
Edit: Good article here about the above settings and others.

yeah. maybe it's because my memory kit is only rated for up to 3200 and i'm already at 3666? but that's what dram calc is saying for my memory type..? i've tried messing with the calc settings and it never recommends anything anywhere close to the 300's let alone below. did you guys use dram calc for your timings?Are you at 1.45v? You should be able to go sub 300.
just wanted to show you this from thaiphoon burner audit. if you look down at xmp specs it's rating trfc at 560 so not sure i'll ever be able to do sub 300...Are you at 1.45v? You should be able to go sub 300.
what is your trfc clock? and are you running gear down mode?Just started getting into messing with my RAM/IF a little bit more after seeing that initially I wasn't showing coupled according to Ryzen Master .. I just have a couple inexpensive HyperX 16GB 3200 modules with fairly relaxed timings to work with. Looking at everybody else's results, I guess these are doing ok

also they are 16GB sticks so they are dual rank. guess that slows things down a hair too. but i wanted to have 32GB and not have to have 4 sticks (which slows things down).
i notice a lot of the super high perfomance kits are 2x8 so prob single rank.

This was from today. I am still playing around as Ryzen Calculator says I can tweak more. I just have not been able to get her to boot with all the setting they suggest and I pushed DRAM V to 1.47 in BIOS which actually runs it at 1.5V. I had to keep resetting the BIOS and going back to this. This is in a 4x8GB setup with IF=MEMCLK at 1900Mhz.
oh my ..what is your trfc clock? and are you running gear down mode?
3800 cas14
The easiest way I've found to rapidly and reliably test ram settings plus prevent possible OS corruption (done that several times while pushing memory), SSD/HD corruption etc. is using the USB bootable version of PassMark MemTest86:Yeah it is a nice kit. 3600C14-15-15-30. I am running, as you can see, 3800C14-15-15-30 on it and it is perfectly stable. I will at some point keep playing with the 4-6 settings that the Ryzen Calculator suggest, if I do them all at once I can not boot or even get into BIOS to make anymore changes. Luckily I have a reset button on the back plane and I save the working settings in a BIOS Profile. Next time I am bored enough to keep re-booting and testing and on and on trying one setting at a time I will see what I may be able to gain. Pretty satisfied with what it is doing now compared to my last kit that was 3600C18 and would do 3800C18. Much better latency and test numbers on this new kit. Below are the Corsair kit results and the G-Skill ones. Shows what better timings gain.
Impressive results here but Renoir looks to take it to another level:

Sub 50ns latency and near 70 gb/s reads shows a very impressive memory controller. The f clocks reaching 2100 mhz+ looks to be how this is achieved. The downside is that the cache is only 1/4 the size. Curious to see how this affects gpus at different resolutions. For the igpu, i would imagine the lower latency helps more than the smaller cache hurts.

It is cheap now but cheaper is always better.True is Ram is not that important in your system.The evolution of DDR4 continues; now available in 4400 CL16!

Pricey and likely higher voltage, it is impressive none the less. This also means that the "lower tier" 4000cl17 type stuff will become much more affordable.

Dang, 4000 mhz cas14. Really amazing how far DDR4 has come.
