help with overclocking ram (msi b350 tomahawk, ryzen 1600, corsair vengeance 3200mhz)

[kevcampbell]

looking for anyone that shares the same system specs as me, after my first failed attempt at overclocking ram i would feel more comfortable if i know someone with the exact same specs has achieved an overclock of the ram

at the moment my ram is running at 2133mhz it failed when i tried to overclock it to 3200mhz

my system specs

amd ryzen 1600 stock

msi b350 tomahawk with 7A34v16 bios (E7A34AMS.160)

corsair vengeance lpx 2 x 8gb (16gb) ddr4 3200mhz with a manufacturer code of CMK16GX4M2B3200C16

would be nice to get my 3200mhz ram closer to 3200mhz, i suppose i may not achieve 3200mhz but close to that would be nice, and the steps you took to get the overclock too would be helpful

at the moment in the bios i have the a-xmp button set to off and also the game boost button set to off? not sure if that is of any help to anyone but thought it may help

any help appreciated

You have the same RAM as me and it is single side Hynix RAM.

This means it will run at 2933 or with a little luck 3066. So far not aware of anyone who had managed to run it at 3200 or faster on AM4 / Ryzen.

Any idea on what I should try next? Should I just try change the dram frequency like before but instead of selecting 3200mhz select 2933? I would class my knowledge with all of this as beginner which leaves me with not much idea of what to do or try next? Should I be changing any voltages or timings or whatever else there is or should I just change the dram frequency, save and exit and see if it boots?

OK I dont have the same spec as you but I can at least tell you what I did so you can at least give it a try!

I have the tomahawk arctic on the latest beta bios (although my ram timings havent changed since the original bios), a 1700 and g.skill 3600C16 samsung b die ram.

I'm assuming both our boards bios's look the same? I dont have the game boost on or use XMP either.

I set the overclock mode to manual. I then choose a memory option from the drop down list. in my case 3333, I can run 3446 and 3600 but 3333 is very stable with tight timings.

I then edit the ram timings manually, i think its extended dram options off the top of my head. In my case I run 14,14,14, 28 off the top of my head.

Wack the dram voltage upto 1.35 at least, you might find its currently set to 1.2 for the lower speed rating. ddr4 can usually run upto 1.5 without issue.

SoC/nbridge voltage put to 1.1 or 1.15, this will help the IMC on the ryzen chip for higher memory clocks.

Theres also an ohms setting you can play with but google that as it starts getting a bit in depth at that stage.

Leave everything else on auto.

get the ram stable, use programs like occt, prime 95 or what ever for some stability testing and then once you get past any cold boot issues and wot not oc that 1600 up a bit. my 1700 runs at 3.85 no probs on 1.35 which is plenty fast enough for me for now.

right well i overclocked the ram successfully last night but this morning i had to change it back to 2133mhz from 2933mhz as it was clearly not stable as when i first turned the computer on it restarted about 3 times before it boot into windows

all i did was change the dram frequency, i did not change any voltages as i do not feel safe changing voltages just yet as i am afraid of reducing the length of life of the system?

also last night after i had overclocked the ram the cpu fan speed was double what it usually is, why is that if i am only overclocking the dram frequency, it went from about 1000 to 2000 rpm after the change in dram frequency

i did read last night though safest dram voltage was up to 1.45v and for cpu nb voltage between 1.10v-1.15v i am just not sure if i should set it to those voltages? i am a total beginner and all i got that from was some general guide aimed at most msi motherboards but i see the reccomended voltages line up with what you recommended too which makes me feel at ease, i am just concerned as i have not done this sort of stuff before, i am concerned with the cpu fan speed being doubled and reducing the length of life for the system or specific components?

as for ram timings i have no idea about that?

here is what my bios look like right now http://imgur.com/a/4j6ff

as always any help appreciated, thank you for the help you have both give me already that is also much appreciated

I just have everything on auto now and select the RAM speed manually. Tried various settings which made no difference for me so just went back to auto and selecting RAM speed. The only advice I can give is make sure you BIOS is up to date.

SOC stay under 1.2v. If you have 2x 8gb 1.15v should be plenty.

CPU if you can keep temperature under load below 70 1.425v should be ok. Realistically ryzen drops off a cliff approaching 4ghz so I'd aim for whatever you can get stable at about 1.35v. Probably 3.8 to 3.9 ghz.

RAM if B-die 1.45v is fine but may not need it.

ProcODT at 53 or 60 ohms can help pull you from cold boot issues.

Timings if struggling set command rate 2T and disable geardown.

I bought couple of sets adn some of them are Hynix, some Samsung E die.
