Liking this £99 Teamgroup DDR4 3000 16GB (2x8GB) 16.18.18.18 RAM, currently running @3200 14.18.18.18 - 1.4v can't go any higher on the frequency even relaxing timings to 20.20.20 and upping volts to 1.5v (for testing only) it's a no go, I might try my luck and push the Cas latency down further but from what I know Ryzen doesn't run odd cas latencies and will default to the nearest even mumber? at least on my setup, surely there's no way I can reach cas12 @3200mhz?

There's a feature you may be able to use to allow using odd numbers in timing. On my board I believe it is called Gear Down and it appears to be a standard in AGESA 1.0.0.6 and higher, and fwir you need to set it to disabled to be able to set timings to odd and lock them in. I'm running even timings on my DDR4 kit as well so I haven't tested to see if that feature actually works or not. But it might be worth snooping around your UEFI to see if that setting is available for you or not if you're going to try odd timings and don't want your board pushing it up to the next even timings.

Though iirc reading, Gear Down being enabled also locks CR to 2T, and you're at 1T so maybe its already disabled? Worth a look I suppose.

For a while that was the case but I think most boards are past that now... or maybe its only a Zen+ thing. I do know that quite often you will see 1t reported regardless of whether youve turned on geardown. Whether or not thats being ignored I couldnt tell you. It's been a while and I dont need it myself, but I do know its at least not the same as straight 2t. Similar ideas in similar practice with different compromises. Iirc the data pins still run at full frequency. Only the command side gets halved down. You could argue thats what makes it 2t and I wont go there because Im not versed lol. But functionally it is different ftom just setting a 2t command rate, where the data rate is halved as well. To me that suggests that you will still reap the benefits of higher frequencies. But again I am just guessing on what little I remember atm.

I remember testing it a little playing with fast speeds/looseish timings... trying and failing to take things further. But what I saw with working tunings was actually a pretty minor deficit coming from 1t to geardown. 2t with no gd on the other hand is almost don't bother territory, unless maybe you need it to pass, say, 2666 or something. But even then, geardown might still give you a better chance. With Ryzen anyway.... if were assuming 3200 is the point of diminshing returns it may not be a huge loss.

I guess best practice is to leave it turned off and try to run a good config that doesnt need it, but in many cases the stability gain turning it on offsets whatever penalty comes with it. Say you're running 3000 cl17 max. Maybe with GD you get that CAS down to 16. Not a bad compromise. Or on the flipside maybe it gives you that bump from 2800/cl16 to 3000. Bumps like that are definitely worth it vs being able to run odd timings or having to run 2t, whether its literally not possible or simply not stable. Comes in handy at that critical speed range where you're right on the verge of a good sweet spot.

Grain of salt. Probably depends a lot on the ram you're running. At the end of the day, most people wont notice a difference between any of it anyway. Stability should matter more by the time youre deliberating on geadown/1t/2t.
 
bios voltage settings are:

With smt on its at 1.8750v@4.025ghz
With smt off its at 1.4250v@4.050ghz

both are prime stable btw. i cannot get the chip stable at 4.050ghz with smt on know matter how much voltage i throw at it. with smt off i can get it to 4.1ghz but that requires the max voltage setting in the bios, that translates to 1.6v. i know that the ryzen 5 1600x will boost the core voltage all the way up to 1.53v to maintain 4.1ghz on a single core so im not worried about setting the voltage in the 1.4-1.45v range for longtime use. just keep it cool.

edit: also to getting my ram stable at 3266 was by accident. i cross flashed a different bios onto my board and was messing with overclocking. my board is actually an asrock ab350m pro4 but i flashed the x370m pro4 bios onto it. (i have a whole thread about this). for whatever reason the 3266 would not pass memtest overnight on the original bios so i always just ran it at 3200. after flashing the x370m pro4 bios i discovered the board would take a slightly higher overclock. i dont know why but all i know is that it works better with the x370m pro4 bios.

without getting into details i can show some examples and show you what ive tried and what worked and did not work in my case. what ive found is that my motherboard(ab350m pro4) will take and run the following bioses:

Asrock AB350M Pro4 R2.0
Asrock X370 Taichi
Asrock X370 Killer SLI
Asrock X370 Gaming X
Asrock B450M Pro4
Asrock AB350 Pro4 ----- (if you think having 1.5v to your ram will get you a more stable overclock than this is the best bios to flash)

and posibly more, i have not tested every single one nor do i plan to.

those are all links to benchmarks i did on my ab350m pro4 running different bioses. you can see that the hardware is the same (minus the gpu at times) as mine so there is some proof and im not just making this up. what ive discovered in my case is that if the motherboard bios i am trying to use has 4 ram slots it will work with my board. if i flashed a bios from one of the other boards that only has 2 slots than the board would boot and immediately lock up. this is about as simple of a summary of my experiences that i can provide.

as far as functionality with the different bioses goes i can say that all b450 and x470 have a different fan controller or the bios handles it different than the a320, b350, x370 and flashing say the ab450m pro4 bios caused my fans to spin at 100%.

im not promoting people do this but if you have an ab350m pro4 and think you need more than 1.4v for your ram you can flash the ab350 pro4 bios and it will let you set the volts all the way to 1.5. it sadly does not allow you to adjust the soc voltage (nor did any of the bioses i cross flashed). the only bios that yielded any benefit was the ab350 pro4 and the x370m pro4 bioses. the rest did not allow anymore functionality.

it was kinda cool tho to think i had a Taichi but oh well.

this is just my experience and im not promoting people to cross flash a different bios onto there board. this was all in curiosity, plus i have the tools to flash the bios back at any time if something goes wrong.

Hey guys what would be a good benchmark to show Ryzen scaling with memory speed? Games? 3DMark? I can run my system with 4 sticks @ 2866 MHz or 2 sticks @ 3200 MHz and I want to quantify the performance I would be loosing

LinpackX showed it preatty clearly for me as i OCd my ram

I run 3.8ghz most of the time at 1.3v or 3.9 at 1.375 both of which I'm fine with, for 4ghz benches I need about 1.43-1.45 and even though my temps don't exceed 70c running cpuz stress test I feel kinda uncomfortable running that vcore 24/7

Yea 3d mark and any game benchmarks you have /can download should give you a pretty good idea imo you might want to look at non gaming apps also, cinebench, ryzen blender, aida64 etc

You wouldn't lose much, the whole high memory speeds thing for Ryzen is overestimated.
 
I guess I’m fairly lucky with my 2400G. I only need around 1.38v to get 4.05ghz. It’s stable at less than that, other than waking from sleep.

2nd gen or ryzen + hits higher frequencies with less voltage than 1st gen
 
My 1700X hits 4 ghz with 1.35V and I have noticed upon launch a lot of people had to push 1.45V+ to hit 4 Ghz, it seems like something has changed over this period of time. Either the silicon got better or newer boards/BIOS had something to do with this.

Not sure if it's a trend with newer 1700x's or perhaps you just got a really good chip either way that's pretty good

In cinebench the results are negligible (~2% more). According to what I find online for gaming this should be in the order of 5-8% and if that's the case I will just sell the 2 extra sticks of ram since I don't really need 32GB anyway and I hope if I ever do need it, faster / higher capacity DDR4 will be cheaper.

The 2400G is still on 14nm, but it does have some improvements that Zen 1.5 (12nm) had. It’s also a late model 14nm Zen, and I suspect it’s binned really well to be a 3.9ghz product at 65W. The lesser chips get to be 2200Gs. I sometimes wonder if the OC is really worth it anyway, as this chip seems content to boost to 3.9 most of the time—especially when not using the IGP.

I'd say probably not then in that case as you will benefit from lower clocks and power when the chip is idle as opposed to running 3.9 constantly with no power saving features on when overclocking, unless of course you know how to overclock using the pstates though I couldn't get my head around them tbh
 
ive been running my proc sense launch with 1.425v. hasn't hurt a thing.
 
Still a work in progress, but I have Ryzen up from the blue team. Gone from an i7-2600K to an R5 2600X.

This new 1900X isn't the best. Im topping out around 4.2Ghz with 1.4125V.. Previous one would hit 4.3Ghz on 1.425V but not sustained as it would saturate the Enermax TR4 AIO.
