good XMP ram for ryzen 3000 under 200€

[Trentonxx]

Hi all,

I'm in italy looking for a sub-200€ 2x8g Ram kit for a ryzen 3000 (3600x/3700x) 

 

since the most popular (ie: cheaper?) kits are 3600c16 and 3200c14 I made a chart to track their price: 

(I mainly shop from Amazon.it and https://www.bpm-power.com/it (the latter has usually 10-30€ cheaper prices to AMZ but it doesn't track on PPP, so I saved you the hassle by doing this chart)

 

 

 

online I read people suggesting buying a 3800-4000 ram and lower the frequency to gain a better timing (AFAIK: 200MHz = 1c is that correct?) 

but I'm afraid that on higher frequency, especially in my price bracket I won't be able to hit it. (even with XMP people complain they can't reach 3200Mhz in some cases!!!)

 

Spoiler

 

how accurate is the XMP profile for the stick? will I be able to fire and forget into my system or it's a lottery even in this case? (I COULD take advantage of Amazon return policy but... )

is manually tweaking ram as complicated as it seems? ( made a previous post asking for guides, and after watching a lot of them I think it's more like a hobby-oriented field than someone who just wants the optimal memory for a gaming build with ryzen 3k)

 

ps: they make a big deal about samsung b-die but it's crazy expensive and useless if I'm going for XMP after all

Get the Crucial Ballistix kit 3200CL16, it can easily do 3600CL14 if you OC manually. 

And you can likely even get 32GB of it under €200 as well.

here is cheap B-die. set manual voltage and timings to get 3733mhz  14-14-14-34 perhaps. 

 

you can probably do better. otherwise just grab some cheap cl16 kit of 3000-3600mhz.

that's a bold claim, at least from the info I've gathered about subtiming ram. 

I'll try to apply as described here: https://github.com/integralfx/MemTestHelper/blob/master/DDR4 OC Guide.md

 

from a previous thread about this same kit one user posted:

Simply putting the sticks in, turning xmp on and then overriding the clock speed to 3733 and setting the fclk (infinity fabric) to 1866 takes literally 3 steps. If this boots, try 3800/1900, and if not try 3600/1800. From there you can tighten the primaries down, check for stability (see the link above), and if that's all you care about then you can call it a day there. Otherwise you can bump the voltage up to 1.45-1.5v (safe on b-die) and try to get the timings as low as you can.

is it achievable? 1.45v for a 24/7 on computer, is it safe? 

does the Motherboard require some special features/specs to achieve it or even a b450 can take a 1.45v ram without issues?

yup. depends on the die offcourse,

nope.

you can do lethal voltage on B350. offcourse you shouldn expect great memmory tracing

with some SOC and some extra voltage, that should be relativly easy. 

 

can allways step down a bit to 14-16-16-36. which would be rather unremarkable. 

 

im assuming you get a good board that will have good memmory tracing.

how do I check for that? it depends on the vrm or the chipset? 

also I'm reading a lot of controversial review stating how they aren't the declared CL  if you know the serial which are b-die for sure I can check by that instead of by name. (Amazon.it does have a lot of Viper Steel 16gb kits for super cheap over 3600, the first time something is cheaper on AMZ than BPM. which is why got me suspicious and indeed lots of people reviewed them as having different timings  ) 

[Trentonxx]

is there a site to browse for Ram aside from pcpartpicker? like where I could check on the fly if it's a b-die? I'm getting crazy trying to populate sheets with price, serial number and finding differend timings on different shops, and different claim from online users @@

i linked that specific kit with PCP as its timings says it can only be B-die. CJR doesnt run like that, neither does rev E.

its decent B-die.

its on a board to board basis, so you cant exactly check it outside of checking for people who test. 

 

mid-high end x570 seems to hold up pretty well. and if you really want the best. ITX and DTX boards is what you would be looking at (tho it does happen that they fuck up the tracing). 

 

any decent tracing should do the trick.

it does not care about which chipset the board uses. nor the memmory VRM (you would need to be using some bottom of the barrel VRM and a lot of memmory for that to matter. Gigabyte uses the same memmory VRM from the B450 DS3H to the x570 auros Xtreme. and the overclocks really do not care)

2 minutes ago, Trentonxx said:

TL;DR at a speed of 3933mhz or greater. take these timings 19-19-19-39 as outlined here and divide the speed by those timings. if its greater than 200, its b-die. if its lower, its not. 

 

at worst you get crazy rev E or you get what you want, good B-die

 

its a way to check if its B-die. its not super accurate. and there are really good bins of E-die that can slip past.

https://benzhaomin.github.io/bdiefinder/ Apparently I found my own answer.

 

if that 200MHz = 1cas hold true even past 3800... I wonder if I could simply get one of these cheap 4000 cl19 kit and live with it (by only turning on XMP)?
but after all a 50€ increase to get a more capable kit to OC.... argh... the variables are adding up, it's a mess

No. Infinity fabric rarely runs past 3733mhz. As such you will need to manually input timings if you get that kit, or performance will actually drop.

You could also just get a XMP kit and not care.

right! I forgot about the half value thing.

yep, I guess I will park the ram research and focus on the rest of the build so I can see how much money I have left to put into the ram (and if it would make sense at that point!)

but really, thank you for all the help

its why you drop timings a lot. just to improve the latency as much as possible.

edit:
I'm watching more of his videos:
at minute 3 he talks about this 3000MHz kit that he claims (similiar part number. mhn...) to reach 4400MHz! (so I guess no problem for a mere 3600? haha)

 

I found this kit under 80€!! o__o!

Rev E kit. very wellknown to clock, but doesnt time all that well. 

 

also buildzoid is testing Ram, not infinity fabric.  as such he keeps that locket while testing memmory.

of course it was too good to be true
