hey PC fans going on with PC world here we are still at course ears gaming HQ
center with Kevin Galloway Technical Marketing electrical engineer - we are
gonna pick his brains because this memory stuff it's really hard to
remember blood album I have to say that because I've forgotten all kinds of
memory stuff and I need his help first question I want to note though because
we have here in front of us the Dominator platinum RG B's the big deal
courses these have these have the capella 'kz LEDs on top but I do want to
know because everybody has they have the RGB Ram I love it the stuff looks
awesome you give up anything to run RGB I know does it hurt the performance at
all no I mean there's I mean if you were to put like a hundred something LEDs
maybe then it would start dip into that power supply but there's enough overhead
there that it won't affect the performance so okay especially not with
the capella X LEDs we're really pushing these because they're better on power
consumption brighter and you fit a lot more which I guess is kind of a
double-edged sword now you can get $100 potentially yeah
the these are were rated for what these are three thousand mega gross yeah three
thousand megahertz yes can you say what the dies are because
there's very much people that are into RAM they want to know or they Samsung B
dies there's the new Samsung a dies what's the feeling on that generally
speaking for like three thousand and above we typically go with Samsung B die
but that doesn't mean we don't use like hynek's and other ones also and for us
hynix is it performs just about as equally as the B die I think the B dies
just really imagine eyes on the internet because of the overclocking scene and
stuff but that's not to say they aren't really good it's just I think maybe
people don't give enough credit to the hynek's chips but yeah
but I guess you should care if you are an overclocked game yeah oh yeah of
course sports yeah mostly if I'm building a
build with just and I'm gonna run 3,000 should I doesn't really matter that much
not particularly no I mean if you're looking to set like some world record or
something and you're cooling with like liquid nitrogen or something then maybe
you know but unless you're other than that for most people it's not gonna
matter exactly yeah and speaking of the the a dies I guess those are the new 10
nanometer chips yes yeah is there what do you think it's gonna change as far as
PC memory goes so there's speculation that it's going to create higher cost
efficiency I guess so it'll basically bring the price of memory down there is
some concern that with the lower clocks I guess that it will have some
performance issues I'm not issues necessarily but they of
performance be impacted but I you know a year over a year you can see that we are
reducing the process size or the process and then we're seeing higher memory
bandwidth so I don't think that's really much of an issue at all yeah I mean that
that's true right because it's not like we're not at hitting 4,000 exactly
almost 5,000 with a smaller and smaller process though and almost you know
easily with some of the 4,000 memory you know it's you don't have to do too much
configuration and especially with like XMP over do CP and stuff and did you
start pretty I guess DDR force are pretty low too I mean it was like 21 33
my first loans and now we're at fairly high o'clock exactly I think that our
Dominator platinum RGB we have 48 hundred megahertz right now is our top
of the line stuff so you also as a regular person should I care more for
higher clock speeds or for lower latency for the regular person I think well yeah
I think you know honestly you know you have the people who are just constantly
running benchmarks and they want to see those results but I think in a real
world like what does that actually feel like it's a little bit harder to
quantify I'd say go with what you can afford
honestly you know the best balance between that personally I run thirty two
hundred megahertz ram and so the timings obviously you can do some configuration
maybe try to tighten them up a little bit but stability I think is really the
name of the game right now so and I guess because when you are
playing with timing and or clocks on memory you're gonna have to deal with
it's just like overclocking right you're gonna have to get your system stable at
your tightest timings and some people are not willing to do that exactly I
mean it because it's I I want to say that it's not an exact science although
there is an exact science to how it works because of all the clock cycles
and everything but it's just I think a lot more work than some people want to
put in you know most of the time when you build a computer you just want to
put the RAM in and get to gaming or something you know so for just the
typical person myself included I just want to jump into overwatch or you know
play on the new goose game that everyone's raving about so I mean for
for the most for that person then just basically going with your XMP profile
yes yeah and that's that's really the
easiest way honestly if you do want to start delving further into it
there obviously all the BIOS they have different settings that you can go
through set all the different timings and everything and you can actually go
above the the rated speed here just at your own risk
yeah yeah the O's the overclocking Oh disclaimer did you finally most
consumers probably just end up they go out they buy the fancy RGB memory and
then they probably never actually even turn on XMP then yeah that stock speeds
yeah 21:33 I'll I've seen a lot more 2666 whatever platform they're on which
you know it's kind of upsetting because they're paying you know if they they're
like oh I'm buying thirty two hundred megahertz Ram they don't necessarily
understand that they have to sometimes manually implement it some other boards
have an auto setting where it'll automatically implement that XMP profile
but you know I think it's it comes down to education and that we're really
trying to do that through our account stuff now so actually speaking of
education hi guys I am I'm asking this specifically because I'm too old and I
can't remember anything more is there an easy mnemonic to remember all the
memories sub timings I mean do we is there I mean there yes yeah yeah it's
cattle and rats yeah that's been mnemonic I just wish
there was an easy way to remember what I haven't hurry right to your ex it's
called the pneumonic is called user XMP I think is something yeah I just enable
XMP it's weird a different way of saying google it but you know it's just really
hard to I guess for an average person to even even if average gamer or an average
enthusiast to really justify the time they really tighten those timings up I
guess yeah and I mean beyond just the time sync it is to get your rest system
running stable yeah I think for most people when they aren't making these
changes they kind of want to know why they're making those changes to so then
you have to like dig through all this information and then sometimes you know
as you're reading your eyes just start to glass over and you just don't
particularly care about clock cycles and you're like you know I'm done with this
I just want to just want to play yeah I hear ya cuz it makes my brain hurt every
time I have to try to remember remember when exactly all of a sudden yeah
actually that comes to some other education I want to get over which is
help me understand dual rank versus single ring because it's not really
marketed generally with a lot of memory and it can impact performance so usually
like dual rank means there's two banks of memory ICS single ranks there's a
single you can see a single rank on sodium where there's two banks or like
there's banks on either side of the the chip or the card I guess yeah but it's
still considered a single rank but if that's because of the form factor and
everything so essentially I'd say a lot of the RAM now is probably dual rank
you know maybe some lower lower capacity ones or a single rank but oh really so
most because I you know I know rise in performance it in the beginning
especially was somewhat impacted by dual rank versus in Guardian and I guess most
of them most like these are dual rank then probably yeah so higher capacity
ones well this is a 32 gig kit so I'll see that's what eight gigs per stick
yeah I mean actually I actually don't know what if these are single or dual
rank that's why sometimes I I it's never ever sort of spelled out sometimes in
the yeah I mean we can just rip these papers off but I mean but it is
important should I should I shop for dual rancors is just kind of like again
one of those 2% improvements in performance it's it's gonna be a nominal
improvement over everyday use its I don't think it'll be perceptible
honestly again if you're running heavy benchmarks and wanting to see like
trying to break each record each time then that's where you'll see that real
difference but under normal use for the typical gamer or workstation user it's
not going to be really noticeable stuff okay and then of course all of your your
gaming RGB memory is unregistered no ECC is is it worth it to have ECC at all or
you know that was Xeon or right yes so if you want the reliability like if you
need or not want but if you need reliability like on a workstation
environment or something like let's say you're drafting or something for a
government agency you of course you want to be able to have that extra liability
in your system so that's but even then that's they'll be using Zeon's and stuff
so yeah and I guess some of those government contracts will require you to
have a exactly ECC and Zeon exactly hmm
obviously ddr5 next year maybe I don't know exactly when ddr5 they're still
kind of fleshing out all the details I personally haven't heard much about it
I'm supposed to be talking with one of our DRAM engineering guys more about it
or actually the I guess the head of the DRAM engineering Jake we're supposed to
meet in Taiwan during Computex just we didn't get around to it is they gonna
what do you what's the quick overview that what do we get more bandwidth more
dope yeah higher speeds more bandwidth
probably I mean it's just robably gonna be hopefully more than just an
incremental change but I'm not entirely sure honestly you think we'll get a bump
in density or potentially and obviously with the Samsung a eyes and everything
we're looking at hopefully having like 32 gig icees and stuff like that too oh
well yeah so actually sorry to rewind back to the 8 guys so we'll get a little
any cheaper because it's a little denser I think so I think that's it's
speculative but I think that's the goal is to have like cheaper memory available
to the consumer to you know whatever growing pains that 8i has you know but I
know there's actually some out there right now they're starting to filter
into the market so oh okay and of course since it's hard to predict how smooth
the transition will go so right remember transitions are always yeah and
a lot of it I think comes down to perception you know because again the
beat I was held way up here you know everyone's a little bit leery about the
the new process and everything so I think it'll be fine though I think
within a year you should see pretty decent maturity on that on that day so
no reason to worry about that yeah definitely sometimes you know you get
parts that have a mythical quality to them so so about 300 a and from the old
days and yeah so huh oh actually well it's gonna ask about run ddr4 head
because it feels like we had ddr4 only feels like well I got five years
out to ddr4 because it was haswell-e mm-hmm - if we do see ddr5 next year
then that was like a four or five year run so well I mean ddr4 will still
probably be produced and in the market for many years after that even if ddr5
is on the market just like we've seen ddr3 still being produced in some areas
and it's still available - so I don't think it'll just completely go away so
for its it's gonna be one of those top-down things you know like the
premium stuff will get they'll have the ddr5 in their systems but I don't think
ddr4 is going anywhere for a while last question and this is a tough one too is
because I've gone through many memory transitions why is it always so
difficult because people get really DDR forwards hard ddr3 was hard ddr2 is hard
every single one of them people just get aggro about and I don't know I
it might just be perception maybe people get comfortable with it
it could be due to technical specifications if if I knew more about
the ddr 5 spec right now I could maybe give a little more inside shirt on that
one and see how the transition to go for there but I could just boil down to
perception you know people not wanting to change yeah exactly it's that inertia
you know okay well thank you check back PCWorld
