<lcvette_> ok
<lcvette_> so scratch the idea of moving crap around
<lcvette_> ill get the 8300 elite
<lcvette_> although i hate buying used stuff
<lcvette_> im the guy who is the 1 in xx who you hear about
<pcw_home> Of the 15 or so motherboards I have none except the slowest atoms (330,D525) have such bad latency with Preempt-RT at 1 KHz
<pcw_home> you could also run the servo thread slower for the time being
<lcvette_> i feel like i want the h97 and g3258, because they are new
<lcvette_> and you said good
<lcvette_> its a drop in the bucket at this point
<lcvette_> unless that asus mobo is no good for some reason
<lcvette_> the way my control panel is setup i just need the mobo anyhow
<lcvette_> no case or anything
* lcvette_ has quit (Quit: Page closed)
<MarcelineVQ> are new mobos more or less prone to being worse for that sort of latency, is it just luck of the draw with each model?
<pcw_home> I have not seem much correlation other than that slower MBs are generally not as good for Preempt-RT and than some MBs are just stunningly good

<MarcelineVQ> got any gigabyte mobo data? :>
<pcw_home> I know the gigabyte 1900-BXBT is OK if you dont use the built in wireless
<pcw_home> 500 Hz servo thread max if you use the built in WIFI
<MarcelineVQ> oh it's a cute little box hehe
<pcw_home> I have a similar Zotac thats OK also cant remember the PN ATM but it has 2 Ethernet ports
<MarcelineVQ> no worries, it's just for curiosity sake. I've got a little old dell with rtai that's doing just fine but it's not neccesarily going to be what the next machine works off
<MarcelineVQ> But I've pretty much owned only gigabyte boards and never had trouble with them so I thought I'd ask
<Tom_L> i've got a couple asrock boards that are ok
<Tom_L> and i'm running an old atom d525 on the mill (rtai)
<pcw_home> this one seems ok  also  but its new enough that it needs a really recent kernel https://www.newegg.com/Product/Product.aspx?Item=N82E16813157726
<MarcelineVQ> and it's even got a parport you don't have to breakout yourself
<pcw_home> yeah a lot of embedded type MBs still have parallel ports (maybe for cash registers/older printers?)
<MarcelineVQ> aww it's not on pcpartspicker
<Lcvette> That one's good? The link?
<Lcvette> $58?
<Lcvette> But needs new kennel?
<pcw_home> there are some faster versions (J3455 and J4105)
<Lcvette> Kernel other than the download?
<MarcelineVQ> huh, funny, someone's build using one is on partpicker though
<MarcelineVQ> coincidentally in a build for a router
<Lcvette> That's where I would get lost
<pcw_home> Yeah I cant remember is stretch worked (I thin I tested by moving a Mint 18/4.14 kernel drive)
<Lcvette> So that is why the older architecture is easier
<Lcvette> Can use established software
<Lcvette> I see
<Lcvette> .... Well I will certainly pray the pain away
<Lcvette> Pay*

<Lcvette> Military class?
<pcw_home> The one I tested on was an ASROCK PRO4
<pcw_home> H97M Pro4
<pcw_home> there are also some workarounds for occasional Ethernet latency overruns/ packet loss
<pcw_home> the way to check where you are is to list all the tmax's after running linuxcnc for a while and see where the time is going...

<Lcvette> This
<pcw_home> (halcmd show param *.tmax)
<pcw_home> I think I paid about $53 for mine new
<Lcvette> Yeah... Well... Supply demand
<pcw_home> I would not pay any serious money for a used Motherboard
<Tom_L> what is intel speedstep in the bios?
<Lcvette> Apparently that g3258 is still a very capable CPU and those h97 mobos are getting harder to come by
<pcw_home> It may sell be that H100s are just as good, I just dont happen to have one
<Lcvette> Bird in the hand
<pcw_home> what is the actual CPU you have now?
<Tom_L> pcw_home is multifrequency bad for latency in the bios?
<Lcvette> AMD A6-7400K FM2+
<Tom_L> also, what are cpu 'C' states?
<Tom_L> and should they be on or off
<pcw_home> off
<pcw_home> yes you want to turn off "turbo mode, AMD cool&quiet etc etc)
* Lcvette has quit (Ping timeout: 260 seconds)
<Tom_L> i turned those off and am getting ~38k servo thread now running ytube etc
<Tom_L> on this asrock
<pcw_home> what CPU/OS?
<Tom_L> does base thread matter on ethernet?
<Tom_L> stretch
<pcw_home> no, no base thread
* Lcvette (ae6a88a8@gateway/web/freenode/ip.174.106.136.168) has joined
<Tom_L> asrock q1900b itx
<Tom_L> i think it's a gen5 cpu
<Lcvette> Lost everything after my questions about the CPU and Mobo in elite 8300
