I agree, I have 2x4GB config with ryzen and my latency is around 69,3ns.

Exactly it is samsung E die.

So on the B350 board, it topped out at 3600 - it wouldn't boot 3733. Not bad for a $60 mobo.

As for what is possible with 4x8GB (32GB total) of Samsung B-die (3200 CL14 binned), I installed the F21 UEFI (AGESA 1.0.0.0a for PinnaclePI) on the Gigabyte AX370 Gaming K7 Board. It boots at 3466 and 3400 CL14 with 4 DIMMs but will error out eventually on memory testing. The highest stable clock I've achieved out of the box (i.e. using 3200 CL14 XMP profile, then changing the speed) is 3333 CL14, all 4 DIMMs populated:





This is high-end memory with a high-end X370 board and a reasonable CPU sample (1800X). I plan to compare against X470 and Ryzen 2700X once I purchase those.

Not bad for 1 year out from launch.

Are you sure that your system is completely stable? Those number are really bad for that speed, I get better results with 3333 CL16

With 4 DIMMs populated?

It passed an overnight AIDA stress test on the memory. Maybe I'll try something else for verification.

See if you can get one of The Stilt's 3200-3333-3466MHz profiles stable, as these have proper secondary and tertiary timings. Don't leave these up to the motherboard since resulting performance is lackluster. These are to be used with at least 1.4v, stock 1.35v XMP isn't enough.

If 1T is hard to stabilize, then 1T+Geardown+even CL or 2T+no geardown should make things easier.


These will require more voltage to be stable vs only tight primaries, but the results are more than worth it:

This requires 1.425v on my particular kit.

----------------------------------------

1usmus over at OCN has dual rank sticks (similar load to 4 SR sticks), and he's been getting better and better results as AMD improves their AGESA code.

It seems he's stabilized 3333 14-14-14-28 with proper subtimings..... you'd usually only see stuff like this on single rank sticks.

Has anyone run CL16 2x16GB 3200 kits at CL14 and been stable? I really don't want to shell out for CL14 if CL16 can be tweaked.

You want 4 x something. Get the 3600 cl15 4x8 gig (they don't make cl14 at that speed) and run them at 3466. $450 (about)

Was working on my R3 1200 build. Updated the bios for the new gen Ryzen CPU's coming out. I noticed the machine was a bit lethargic and I think my vcore may be low for 3.85ghz. I was 1.2875 and I bumped it to 1.3v and then 1.31v. It's watercooled by a 240mm AIO. What is the base Vcore for an OC'd Ryzen CPU? My ram runs XMP settings 3200mhz perfectly with all the correct timings since the last bios update before this new bios.

That is a great chart. Looks pretty accurate up and down. I knocked the R3 1200 down to 3800mhz and 1.285v. I will leave it there for a few days. It's running without the lag now. Most people would not notice a slightly lethargic response to their system. Sometimes computers will eventually hang. The best way to fix them is to run the system at a lower clock rate for a few days.

Quick help here. I am overclocking some ryzen builds and some friends are to careful.

Safe voltage
Vcore : 1.4V - LLC2 (max 1.4V, under load ~1.356V)

SOC : 1.2 LLC Auto (max 1.181V, under load ~ 1.175-1.155V)
- with 1.125V some did crash

Safe enough?

- This configuration runs different core clock (depends on lotery), but 3466MHz memory.

They are all safe voltages. When you consider the cost of 1.4v vs. the benefits of increased performance. You can run low voltages on ryzen but over time the machines could become sluggish which is directly attributed to an unstable OC. The benchmarks look good but the system hangs ever so slightly at times. You may have a machine hang while in sleep mode. Requiring a hard reset of the system.

Thanks,

yeah I do testing and when i get stable 1.375V for 6-10H still go for 1.4V at same settings. Same goes for SOC 1.05-1.15V then I add 0.05V for maximum stability (mem test for 8 hours).

Anyone have a favorite M.2 SSD they used with a Ryzen build?

I grabbed a used 500GB 960 EVO last year for the 1700, was debating re-using that for the 2700X or trying a PM981, but kinda wary because it is OEM and not as easy to get support as the retail line.

I went with a 1TB PM981 during those ebay 20% off sales. Took the longest time to decide between that and the 960 EVO but the 4k random read/write speed improvements were too big to ignore, so I took the risk. So far so good but that won't help me if it craps out. I haven't had a hard drive or SSD fail ever, even old Maxtors dropped on concrete, so I'm feeling pretty lucky.

I'm guessing the real 980 EVOs will be out soon if you want the support.

edit: It is mildly annoying that the drive is green rather than black like the rest of the PCBs in my computer, but I haven't thought about that since I installed it since I don't have window bling or any silly lighting

Just clean installed the latest Win10 1803 on a Gigabyte AB350-Gaming 3 (BIOS F23d) + Ryzen 5 1600 + G.SKILL FlareX 16GB (2x8GB) DDR4 3200MHz F4-3200C14D-16GFX. The mobo hasn't been used for a month or so, just wanted to get it set up for a benchmark session. Install went fine, even I was able to generate the sys info files with memory running @3200MHz (CPU-Z, HWiNFO). But after copying and zipping out some stuff, BAM, all of a sudden the PC went black, had to turn it off.

From that point I couldn't get to boot with XMP profiles, PC tries to boot 3 times but resets back to default settings. Tried to manually enter memory timings, no change, system cannot boot.

I haven't had issues with this kit, really don't know what happened. Reverted back to F22, but no luck. I'm clueless really.

It did not, after a few minutes the display turned black, had to turn off the PC. After that although the BIOS shows that the XMP profile is enabled only default speeds are reported via system monitoring tools.

To clarify, have you tried any other settings other than 3200, such as 2933?
