You're reading it wrong, but don't feel bad as it's definitely an easy mistake in general, nevermind when the screenshot was cropped down like that! (I only figured it out a couple weeks back heh)Yes, but what sticks? From that photo it shows f4-3400c16d-16gtz, which are 2x8GB sticks, though if they are 16GB sticks then they should be F4-3400C16D-32GTZ?
I'm wanting to upgrade my x58 system to a Ryzen system, but this memory thing is holding me back until compatibility is smoothed over.
Ah ha! You can tell i'm an x58'er (as I haven't upgraded forever). Thanks for taking it easy on an old-timer and being nice about it, young whipper-snapper!You're reading it wrong, but don't feel bad as it's definitely an easy mistake in general, nevermind when the screenshot was cropped down like that!

They say F4-3400C16-16GTZ
Which translates to Trident Z DDR4-3400 16GB CL16 module. From there, you just apply the SPD timings in the table to determine that specifically it's the 16-16-16-36 variant.
CPUZ's tab doesn't say the Memory KIT name, which is indeed what you put. The difference is one silly letter... "D" which in the kit part number, denotes "Dual Channel", and Q denotes "Quad Channel". As such for those, you would halve or quarter the "-##GTZ" to get the module size, as you had done.
lol Like I said I had only figured out their 'coding' a couple weeks back Though, while it's not a problem... I don't know how 'young' I am hahah T-12days I'll be 34 hahaAh ha! You can tell i'm an x58'er (as I haven't upgraded forever). Thanks for taking it easy on an old-timer and being nice about it, young whipper-snapper!
I'm really interested in the Ryzen platform, but really wanting 32GB for vmware. 24GB is okay on my x58 hexacore, but an octocore 32GB system just seems so enticing. That and all of the IPC upgrade from a basically 990x equivelant xeon.
I'm going to probably wait 2-3 months to let this memory compatibility issue get ironed out and matured before finally upgrading from my old x58 workhorse.
That's been posted about all over. I believe in this thread, too, but if not then in a few of the other threads on [H]. Ryzen has some quirky issue with Odd CAS timings (the first number in the sequence). I suspect it only occurs above 2133 since for me at that speed, 15-15-15-35 works fine. I haven't tried any other speeds besides 2933, and 3200, but can confirm that at either of those speeds odd timings do not work and will auto adjust to one higher (at least on my board). 14-15-15 works, 16-15-15 works, as does 14-13-13 or 12-13-13, but not 15-15-15 or 13-13-13 at either 3200 or 2933. *shrug*Noticed some oddness with my ASRock b350 pro4. Have two sticks of gskill TridentZ 2x16 @ 3000 (15-15-15-35) in the board running at 2400 right now. Bios is the new 2.20, but this is also true for 1.50 and 1.43.
If you push the mem speed in bios to 2400 from 2133, leaving everything else as "Auto", the board won't post. If you actually choose a CL (16 in this case) and change nothing else (leave the rest of the timings as Auto, leaving voltage untouched), the board will now post and be stable. Going back into bios now shows the rest of the timings have been set so the result is 16-17-17-40.
XMP at the CL15 timing is visible but won't actually work if selected. Just some odd behavior.
lol You forgot to tell us how much your stick cost you, though!How about this!
ASUS PRIME B350M-A with Ryzen 5 1600, and 1 stick of Kingston ValueRam DDR4 2133 8GB KVR21N15S8/8
Results - 2933MHz @ 16-17-17-42 1.3V! Achieving 21GB/s in Maxxmem with just one stick! How good is that! Forget the overpriced Intel XMP memory!
Well I bought it last year for $47 when ram was cheaper. We have tested a couple high speed kits on this board which I posted results for earlier in this thread. Couldn't get past 2400MHz on a 3000 rated 16GB kit, and 2666MHz on a 3200 rated 16GB kit. I wanted to experiment with a single stick that was decent quality, single-sided and had no XMP profiles, and it just goes to show you what you can do with entry level ram. Although it's hard to find, Samsung does have some DIMMs available with the B-die ICs so I will track one of those down to test.lol You forgot to tell us how much your stick cost you, though!
That module is $62 on NewEgg.
I ran a test for you - 13.25GB/s in MaxxMem ver2.04. I have the CPU at a conservative 3.3GHz with no SMT and all features disabled in the BIOS. The great thing about the memory controller is both CPU and memory performance scale to respective speeds, so if you increase CPU speed and leave memory static you will see a noticeable increase in CPU and memory performance in benchmarks anyway. It's a fun chip to play with!I don't suppose you'd be willing to do a test for me, running it at DDR4-1866 at 13-13-13-31 and telling me what you get, and also what version of MaxxMem?
Chew had gotten 2x Double-Ranked modules (8GB though) running at 3400.Single rank seems to be the only ones that can do 3200 from the results listing on the first page of that thread. No 16Gb single rank that I can see..
Edit- Beardless Duck had 4x8 GB running at 3200 on the list.
o_0 Yours... in CPUz, says it's running at CL15 on your motherboard??I edited my op, but now up to 2666mhz cas15 with bios 0604 (new AGESA). No post at 2933c15. Slowly getting there.
You're right, cpu-z says c16. Not sure why that is but i'm not too bothered. I may try upping timings some and try 2933 again but not sure it's worth messing with at reduced timings. I'll edit the op.o_0 Yours... in CPUz, says it's running at CL15 on your motherboard??
I can only confirm it working at 2133 on my Titanium, and might work at 2400 since the new "Memory Try It!" option they added with predefined timings, has a choice of 17-17-17 at 2400.
Otherwise, everyone else seems to have issues running Odd numbered CAS latencies, and at 3200 or 2933, they are set in the BIOS to CL15, but something along the way (Ryzen? Microcode?) forces it to being CL16.
Also for what it's worth, my Titanium with the latest AGESA (in BIOS it reads as 800111C), 3200 @ 14-15-15-35 does not work; however, 3200 @ 16-15-15-35 does.
I'm also able to run it with a BCLK of 102 (max on this hidden BCLK option is 103), meaning 3264 @ 16-15-15-35 is working.
If T1 == Command Rate 1 (CR1), then I knew that it usally does. However, I believe in a screenshot TopWeasel sent me, his was reporting as running at CR2, so there seem to be specific instances when it doesn't "always" run at 1, but his definitely was the only instance I've come across so far.
So how do you like the B350 Mortar? Thinking of picking one up.MSI Mortar B350
BIOS 7A37v12 (just released with the R5 support and - Update AGESA to 184.108.40.206a.
R7 1700 (stock for now, had it at 3.8 locked with 1.25v and 20% LLC in prev bios but havent attemped yet in new bios since I wanted to squeeze the ram)
GSkill Ripjaw V 16gb 3200 : https://www.newegg.com/Product/Prod...&cm_re=gskil_ddr4_3200-_-20-232-181-_-Product 113 bux right now GET SOME
NO its not on for my board but ram prices on 'Ryzen ' ram are just criminal so time to gamble.
Running it at: 2933 14|16|16|34|69 1T
With new bios there is a 'try it' feature with a bunch of ram speeds and timings so I did try a few and this is the fastest freq and lowest timings I can get rock stable. So, still at 2933 but stable with tighter timings on this (3rd) bios release.
Still will not post reliably at 3200 with any timings. I did get a good boot at the XMP settings (input manually in bios) and ran fin all night. However reboot the next day it took a dump and recovered at 2133 1.2v booooo.
So far I like it a lot. The bios post has been getting faster with each new bios which was my main concern. The latest bios I mentioned has a better look and more ram features so it has been improving steadily. For just under 100 shipped from newegg it's a solid value.So how do you like the B350 Mortar? Thinking of picking one up.
I have mine at 3100, just could not get 3200 at 1T. Have not tried it at 2T tho. My ram runs at 16 for latency tho, I didnt get the super low latency sticks, figured that was asking for trouble on a new process. I dont know if thats close enough for you, but I am happy with it. I am using a Crosshair VI tho so if you have that motherboard I can go over what I did to reach those speeds.Been keeping an eye on this thread, but if anyone can get 32GB (2x16GB) working at 3200 with 14 or 15 latency please post your RAM and settings and MB you are using please
