Author: datonybSubject: X370 Taichi build advise
Posted: 12 Dec 2017 at 2:57am
well to answer the few points in a broader covering reply
the samsung b die from day one has been the least painful ram to run with the taichi
as with most ryzens and amd am4 chipsets
the reason its b die at is really 3200 upwards is because any other dies seems to struggle on intel or amd over 3200mhz (with sensible sub timings anyway) compared to hynix etc which must have much higher/looser timings
and then you require 32gb
which would have to be carefully choosen 4 x 8gb single sided ram sticks OR 2x16gb double sided
the old rule of more ic's (chips) to control the harder it is on the cpu's IMC comes into force here
the thing is the ryzen cpu does really like ram running at 3000+ mhz to optimise its own internal clocks (the infinity fabric) in a similar way the older amd chips liked a nice high northbridge
sure it will work with lower speed ram, but i would still advise the old saying 'buy cheap - buy twice'
as far as motherboards go the taichi does indeed seem to be very forgiving about ram compared to others in its price range (we wont discuss my quirk of extreme fortune on a friends cheap msi b350 board and an insane stable overclock of his cheap ram)
at the end of the day no-one can give you 100% sure fire choice of parts, and we see that with all the manufactures boards not always running the qvl ram at advertised tested speeds
but i do know the best chance does seem to come in the samsung b dies flavour
as for stability ive had the taichi for over 6 months now with gskill tridentz 3200-cl15 2x8gb sticks
aside from my morbid interest to see how far it can go, its never played up once at anything which should run as advertised, this even goes back to the luanch time bios versions where hardly anyone got over 3000 mhz ram stable, mine just worked at 3200 after clicking the xmp button

no crashes no lags no boot issues (the worst it done was auto change the cl15 cas to cl16) and carried onto boot cleanly
this was/is an issue with the amd agesa not wanting to use 'odd' numbered cas settings (there is a workaround, but isnt actually needed with decent ram, as you just lower it down to cl14 as is my case)
as for the patriot ram ?
who knows if its using the samsung b dies im sure it will behave the same as the rest
a clue can be found that if the primary timings are all equal it usually is
eg @ 3200 cl16/16/16/16 or cl14/14/14/14 etc ,this would not be sure fire but a good indication
and the size of the ic's means it;ll have to be an 8gb single sided or 16gb double sided stick
i hope this helps but may well have left more indecision in your choice
if your getting someone else to build it for you ,then there is also the fact if you go with his choice then he can be the one to worry about getting it running
maybe discuss some of the findings you have made with him ?
he may have had good experiance with patriot ram before (as i have had some years ago on intels) and is leaning towards that brand, i bought gskill for this build due to being able to confirm 100% the kit i choose was b dies (also never have they been on the taichi qvl)
in the past i used to favour corsair xms ram as a certain quaility and compatability ,alas corsair seems a bad choice for ryzen systems now
as i said have a chat with your system builder advise him what you have read maybe hes not that used to ryzen systems yet and might be glad you pointed out some experianced posts on the internet
