#1190879 The age old question, a PC for the relos...

use to use thunderbird but these days i just use gmail it seems much simpler and has less problems

the single core performance of the Celeron J3455 is around that of the old athlon x2 which will make things load a little slower with a ssd than it would with the pentium but otherwise it should operate fine

its a fair bit quicker than the old e350 atom build i replace with a i3 nuc




#1190663 need a new GPU for my 3570k help

Posted by Dasa on 10 April 2017 - 10:58 AM

450-550w would be plenty for a rx 480

650w for overclocked ryzen and 1080ti

that cm has a longer warranty and higher quality caps than the corsair

the cm vanguard also has about the highest efficiency around in the low wattage range

 

16g is ample for games but if your using it for other work loads its worth considering

low clocks on the 1400\1500x is a shame but with some luck they will still hit 4ghz oc

looks like the 6 core cpu keeps the full 16m l3 cache but the 4 core disables the ccx leaving you with just 8m l3 which may also fix some of the latency related performance issues in games with ryzen

build updates were overdue

low Budget overclocker is gone for now hopefully amd can remedy this with there 4 core 8 thread cpu later in the year

updated the small build squeezing in as much power as i could hopefully its all ok and i havent overlooked compatibility problems (fair chance)

also added a budget ryzen workstation build

will do some more updates yet




#1189733 1080TI

Posted by Dasa on 10 March 2017 - 07:38 AM

reviews are out and as expected it edges out titan x while costing much less at $699us rrp same as the 1080 founders edition, $100 more than the gtx 1080 non reference at launch and $200 more than it is now

http://www.xtremesys...-1080Ti-Reviews

au prices are a bit of a rip off at $1200

truth is i dont think any of us will know for sure for some time yet

there is much work to be done before we will get a real look at how it performs in programs like games

 

edit

apparently he said bulldozer is crap in that review so i may have gone to far with my fanboy comments above

high res results really dont matter
it still performs the same as a i5 7400 in anything with bad threading or 3770k-4790k in games with good threading just the gpu hides the difference vs faster cpu once the game becomes gpu bottlenecked

all mb should get bios updates in the future to improve there overclocking capability with ram but at this stage asrock seems to be the furthest behind with its mb only supporting up to 2666mhz while all msi\gb mb claim 3200 and asus only has the one mb capable of 3200 at this stage

i3 nuc are good for playback and general use

the larger models only have room for a single 2.5" drive and a m.2 ssd

apparently it hit 5.2ghz at 1.85v on ln2 -200c and claimed the wr for cinbench on a 8 core 16 thread cpu beating the 5960x at 6ghz




#1188523 Pondering a workstation build to process astro images + occassionally play games

Posted by Dasa on 09 February 2017 - 10:26 PM

 

i wouldnt bother with aio there expensive more prone to failure and loud for the level of performance they provide


Can you point me to some failure rate info?

The main reason I haven't looked at this myself is because if liquid cooling fails it can do more damage.

As for noise & performance, from what I've read it's only the very top end air solutions that stack up and, as I've experienced, they are very dependent on mobo layout.

 

no failure rate info other than seeing a number of reports on forums of dead pumps and leaks
corsair has a good 5 year warranty on many of its aio which may also cover damaged parts
but i have never seen a hsf die just fans which aio use too and it usually takes a long time for cheap sleeve bearing fans let alone high quality ball bearing fans to die
 
there is some half decent cheaper hsf like cryorig h7 that fit just about anything a aio will the performance may fall a little behind but there still in front on noise
 
big hsf like nh-d15 can block the first pci-e slot on some mb although the nh-d15s gets around this and if you combine tall ram sinks with side panels close to the hsf hight limit you may have to forgo the second fan
 
 

g__day any idea what i need to do different to get comparable results with all cores in use with DeepSkyStacker?




#1188418 Pondering a workstation build to process astro images + occassionally play games

Posted by Dasa on 08 February 2017 - 09:47 AM

unfortunately i have never had the chance to use more than a quad core 8 thread cpu so my experience is limited in that regard

 

rather than running one big expensive dual cpu system for processing how would it be to run a few 1-2k systems?

zen would probably be great for this option

maybe build a zen system for your main uses when its out then if you want some more processing power look at a 32 core naples later in the year running both at once should really crunch some data and may even fit under the 6k budget

dam memory bandwidth on new dual cpu systems is insane

mind you my overclocked dual channel system is competing with that 2133 quad channel bandwidth but with a much lower latency so a overclocked quad channel system would do ok to
