First time RAM timing tightnings speeds

[Nexblitzer]

So I just want to know what sort of timings are can be had out of a Samsung B-die CL16-16-16-36 4X8GB kit at 3600Mhz. Not looking to increase the XMP per say, just perhaps tighten timings. What can I expect to get with this config?

14-16-16-36 should be easy if 3600MHz XMP works, if it doesnt just add some voltage. CAS wont really go lower (i.e. the first number) but the rest could.

Wait CAS is the first number, and you put 14, thats lower then stock XD, I do get what you saying though

honestly which kit you have doesn't always tell you what quality of sample you're working with. My 3600 cl14 b-die kit doesn't like running above that spec much at all, but my 3200 cl 14 b die kit is an overclocking champ. You will be limited by the quality of your ram controller and motherboard quality as well, just something to keep in mind

Yeah like I said I ain't planning to overclock the XMP profile per say, just tighten the timings a little.

I get that, but the quality of your sample will determine what sort of timings you'll manage to squeeze. If you're going to do primary timings then...

but if you just want to do Tertiary timings it depends on your platform. If you're running a Ryzen processor the DRAM Calculator from 1usmus is a great tool, but if you're keeping it more simple than that you could try basic stuff like running at 1T timing but that can be unstable with 4 sticks depending on your platform

I recommend just manually lowering each number unless that causes problems. DRAM calculator is only good for saving time and it's only sometimes good at it.

So I'm planning to use RYZEN 5000 series, so the latest and greatest on a high tier X570 board. So no real low end components in that regard.

I've heard though, That some timings have to be within multiples of another? If that makes sence, I THIN what I'm trfying to say is there has to be a bit of uniformity to it, not not lowering them willy nilly.

multiples? Never heard of that. There are some variables that can only be in some numbers (e.g. CAS must be even numbers with Gear Down Mode enabled) but no such thing as "multiples of something else" as far as memory timings go.

16-16-16-36 would be more efficient than 16-19-14-35 if that's what you're asking.

Thats probobly what meant to say then, even timings, uniformity as such that I was pointing to.

Also what brands of board would you recommend for timing adjustments? I've read that Asrock and Asus boards, automatically optimise secondary tertiary timings when you first boot up or what not.

MSI > Asus = gigabyte with manual dual BIOS control > Asrock >>>> gigabyte without dual BIOS control

memory training is done by all boards

MSI first? for what reason in the majority? Just curious. Also there is a lot of forums complaining about how certain gigabyte board in the past have had really loose secondary timings, that needed to be adjusted to get the best performance.

so the most efficient thing u can do with a 16-16-16 kit is to increase the voltage to anything below 1.5v, give it direct air flow, and hope 14-16-16-36 3800 works with zen 3.

 

The first thing i'd try is 14-16-16

then if that's stable 14-14-14 (likely won't boot), but if it does grats

then inch it closer to 3800 if either of those settings are stable

 

after all of that is stable, start working on secondary timings.

Trfc 240-320

tfaw 24 or 28 are the 2 main ones.

 

Or just use ryzen ram calculator.

I see, thankyou! I may give that a try!

Their boards just consistently did better than other brands.

 

Now that you're adjusting them manually, it doesnt matter what the stock settings are right?
