With gen trakin 3rd party firmware I get 300mh at 1225 watts so hardly that big a diff at 280mh at 1100 watts .......big whoop.....my Titans can run just fine with
Given the A4 specs a "1000 watt power supply", which will probably be pulling somewhat less than that in actual usage, where the HELL are you coming up with that 1100 watt claim?
Yes, the Titans are fairly close on efficiency - they'll probably stay profitable for the forseable future unless you have REAL high electric rates - but they're not nearly as close on efficiency as you seem to think, *AND* their track record of many dead cubes makes their reliability very suspect while the A2 was rock solid for almost EVERYONE that ever used one.
I can see a day, probably in the next 2 years likely less, when the A2 becomes non-profitable at 3c/KWH electric and the Scrypt miner market becomes basically a 2 horse race between the A4 and Titan - but those Titans that are still running by then will definitely be the LAGGING horse in the race.
I thought the new specs on the A4 were now 1100 watts at 280 mh.....I thought it was stated as such in the threads ...also a price of 2100 bucks now ? I'm also not sure
if the group buy is still going on? Feel free to correct me ..but the figures I was working with
Point taken...but with gen tarkin 3rd party firmware and other mods (maxumark bracket..copper heatsinks replacement on all dc/dc's and gellin extreme thermal repasting) they will very likely go 2 more years now..the stuff has NEVER been as stable or run as good
my stuff is running now with above on dc/dc's 10c to 15c less tempature with the copper heatsinks and a 3000 rpm fan vs their 1500 rpm fan (20% more noise) and also there is a lot of folk
that can fix and revive cubes.....now In other words my temps etc and stability have never been better ....after the above mods I was running the ones I have here in the basement
at lower temps when it was 84F this summer then the previous winter at 60F.....I actually gained 50mh total plus on the conversion...the dies that are down are still down but now all else
the last 6 months is solid it seems (again to your point working around some dies that are down)
Then again used Titan equipment (if it ever shows its unicorn hoofs again) might be more of a risk then the A4 ..people tend to move the shaky stuff in used asic's etc and to your point
you are not sure what you are getting and it is over priced...probably because the stuff for sale is unmofied (from what I've seen) and thus let the bidding wars begin from those
who know how to fix/tweak them above
But the point of failure on folks running Titans now has improved from the above hacks dramatically imho for extending the life of the units...hr and 1/2 mainly due to lightfoots fix of such and gen tarkin's firmware....the mods are damn helpful for long term life too temp wise decrease
Hopefully a community of cooperation etc will come up for your A4's as they chug along..and extend improve their life too as time goes on...but working great for me so far
So you are correct Titans WERE flaky and had issues in 2014 (nov in my case 2 dead dies on orig unit) BUT (not counting the summer knc liquidation yeech) IF you have a Titan that works now very likely it iis over the hump and will work just fine for the next 2 years...especially with the gen tarkin firmware and repasting all mentioned above
As an example I have a buddy with 40 titans or so that are rock solid (some modded some not) you can work around the dead dies on some and the rest is stable
heck I may even get some of my problem dies fixed by lightfoot (dare to dream have enough hash now I can send in some 1/2 working stuff for the heck of it on a hope)
Anyway all the Titan stuff that has junked out has probably been that way for the last year....the shot stuff is off the market whatever the amount that is from 2 years on
..there is new life in them now ....at least it seems so from my side and my buddy with above mods
HOPEFULLY your A4 will also be solid like the A2......I may still get one or two...(with my hash that is 1 month hashing lost to pay off an A4) But likely I will wait
see if the warranty improves or how the firmware is etc..if it costs me 200-300 more a unit and I lose some too difficulty by waiting a month or two .. so be it...but even if the A4 was golden child....at a 12 month plus ROI right now and again that pesky 45 day warranty ..I'd likely wait anyway ......as to folk the must/need/want to jump into scrypt mining in a big way
and get multiple A4's on a price pump hope of BTC and say LTC floating along onward and upward..tough choice...I did that back in the day got lucky...but scary bet
but as they say big risk big reward or big risk low reward...seems this kinda thing always shoots to the edge and either flies upward or falls off the edge downward
I may still get on board..but right now too many moving parts (firmware? 45 day warranty? 12 month ROI) .....then again not a lot of Titan cubes floating around I can repaste
and fix either
So anyway wish all luck on the A4 but sitting on the fence now
