is your miner in your wallet directory?

i have equally clocked/branded 7950's that have varying mem straps and they perform between 200MH and 400MH, quite the difference.

unless there are other system limitations.

both 4gig system ram and ssd equipped.

i have 290's in the 600's

you are under performing.

try a different bios.

you can buy accounts or if someone is nice enough you can have one donated.

go to the Altcoin announcement thread for pascalcoin and participate there. first read through a few pages all these questions have been asked before.

congrats and happy birthday man! 

that is normal.

it wont show "Active" until you have 5 connections.

you should still be able to mine with less than 5, but you're at risk to orphan due to slow propagation.

with a properly strapped bios the 8pin power was my bottleneck lol.. like 12g wire up in smoke.

you can squeeze 360h/s out of a 290.

it's a thing and should be considered.

i've seen difficulty correction algorithms so far out of whack the block chain had to be rebooted.

this post has actually started me tinkering with a freebsd box again now that amdgpu is a bit more seasoned. i'm confident i can get something going and will report back.. eventually.

alternatively DragonflyBSD and OpenBSD look like interesting prospects with surprising compatibility.

the only real advantage of your x interface is having aticonfig at your disposal to set clocks real time.

once your bios is dialed in with stable settings your clocks are set during boot so you can just stay in console, not that i've noticed a speed difference.

of course there are drivers that work best, and a non systemd distro might have gains..

can anyone comment whether a vanilla archlinux install beats other distros by any real margin for mining?

debian with a minimal x interface or console alone once your tuning is dialed in.

you are asking for free advice.

be mindful of the value free advice often brings, also be aware of the environment you have entered.

since the boom in 2013 (and the subsequent bust) there seems to have been a taste developed to tax some of the easily earned profits from those entering or still naive in the crypto community.

whether it be from misinformation, disinformation or flat out scams.

that being said, 3 grand is not a high sum to start with for investing. i would grab as many gpu's as possible and a spare power supply (or two) and just fill the pcie slots you have in your home systems as it is.

ATI was acquired by AMD in 2006 and the branding of ATI has not been used since 2010.

I remember my default system datasheet back in the day with a Trident 512k ISA video card and the possibility to upgrade to an ATI MACH series card with some super exotic name. It had DRAM standard, VRAM as an option, and a price point just as exotic as its name.

I went with the Cirrus Logic card instead.

Shaking off the memberberries, the main reason you see AMD as the prevalent GPU brand here is cheaper entry into the mining market.

more of the mining software devs tend to focus on AMD as well.

with each upgrade from mining optimization the payouts usually equal out as everyone has access to the same software.

if you're vigilant and check this thread often, installing an upgrade immediately may give you a boost for that 1/2 day or or so before others roll it out in their large scale operations.

likely a big reason this thread has over 1.5 million views.

how did you come to use dwarfpool? did you consider or try any others? do you use any online calculator and check what your earnings should be? how frequently?

your payouts are pretty random so its tough to tell what your usual 24h earnings are but .22 ZEC from 3800H/s as per your stats at the time of the screenshot is a bad result.

i wouldn't call it meaningless at all.

gtk about antpool.

i think a community database reflecting pay per hashrate is a great idea but having reputable contributions would be difficult to authenticate.

i'll see if i'll have another go sometime down the road.

i believe amd-gpu-pro open source driver set now allows mixing of various generations of amd gpu.

its an interface under development though and tbh i prefer the tried and tested aticonfig catalyst drivers.

when it comes to nvidia and amd you still have to segregate no matter the platform (unless you're a wizard with netbsd)

tried the 290 rom today and it would crash all instances within 5min unless I used the highest voltage rom and even then gains were not discernible against stilts good old minus .25 mining rom..

was worth a shot, do you have anything for the ghost 7970 philip is trying to sell in the classifieds?

are you sure about that? their payout page at https://www.f2pool.com/help still lists 4% and BCT thread announces no plans to change.

i guess every little bit helps but zcash being such a new coin the fees don't surmount to quite so much just yet.

BTC and ETH pools it's certainly a factor for me, ETH not so much due to age but the processing of complex contract code with blocks.

LOL if you want to commission that kind of case study I may be game.. otherwise someone with some real api experience is welcome to take the reins on this one.

I think 4 days is reasonable, as the calculated average when compared to each days result can attest for.

I agree more is always better in this case but the law of diminishing returns must be considered here when attempting to achieve a decent mean between pools.

F2pool is 4% fee unfortunately and the others 1%-2%? It's not enough of a difference to make any waves but a definite oversight on my part. Thanks for shedding light on this point.

yvw all, I know I have taken/learned enough from others' posts that I'm happy to put some work into giving back for a change.

I realize I may have come across as a bit of an F2pool fanboy in the past (love the PPS consistency) but I'm not one to limit my options, and alternative ZEC mining experience for me was admittedly only with Suprnova which I found terrible.

Since I had a unix box with four identical 7950's on hand (all Sapphire Dual-X HD7950, same undervolted bios, same modest clocks totalling 195h/s on claymore 10 in nofee mode) I decided to have a go at some statistical analysis.
 
Included in the study were F2Pool (of course), SuprNova, Dwarfpool and Flypool.. Unfortunately I wanted to keep all stats from the same rig or else coinmine.pl would have been a target of mine also. Maybe down the road.

Of note during my sample over 4 days this week, day 2 posed a bit of a glitch or DDoS attack on Dwarfpool's stats front end but all shares were counted and awarded.

After day 2 I switched to ssl encryption for Flypool and Suprnova since they offered it. Since I was in nofee mode this posed little to no difference in coin output.



*RESULTS AS FOLLOWS*

The basic result (as an F2Pool fanboy) was fairly surprising:

SuprNova daily average output over 4 day sample: 0.01725
F2Pool daily average output over 4 day sample:     0.018209995
Dwarfpool daily average output over 4 day sample: 0.0179318525
FlyPool daily average output over 4 day sample:    0.01968

This was for an consistent average hashrate of 195H/s

Dwarfpool roared ahead early on, took me completely off kilter but had long spells with no blocks found on day 3 and then at the end of day 4 which substantially lowered its average and allowed FlyPool to take the crown overall.

Daily output was as follows with top performers of the day in bold:


        Day1                Day2                Day3               Day4           

Supr    0.0167             0.0184            0.0169             0.017     
Fly      0.01944           0.02004           0.0202             0.01904
F2       0.01913016      0.0170826       0.01834198      0.01828524
Dwarf   0.02102721      0.02075111      0.01224441      0.01770468


Suprnova, as I have commented in previous posts.. continued to substantially under perform. This time during the whole 4 day sample period coming out on bottom by a fair margin. Shortly after switching to Suprnova's encrypted ssl server there was a 15 minute span where I was not connecting to the server for some reason, slightly lower (than the usual low) output can be noted at 68h sample period. Otherwise up time was 100% for this pool and all others.

F2pool wasen't ultimately as superior as I had thought. It was consistent however. Dwarf was a serious contender, not sure if it was plain bad luck that the DDoS and 5-6 hour periods without a block happened during this 4 day span but I did email the admin with some questions and received a prompt and reasonably helpful reply. I would certainly be willing to give Dwarfpool another try in the future.

If I were to do this over again from the start I would have used Suprnova's anonymous service instead of creating an account and logging in to check stats periodically. At this point I think I have lost enough profits with them though, and will no longer point any of my miners at those servers.

Below are samples from about every 4-9 hour ranges. The hour periods aren't quite accurate but what is 100% accurate (and most important) is that the samples were taken from all four pools at the exact (within a few minutes) same time.

Complete results below:


I captured screen shots during each sample period as available for viewing/confirmation here: https://mega.nz/#F!LJhCnbzC!OXdEiM08UK8_7FFeBQHwmw.

I hope this is helpful for some of the ZEC miners out there. I welcome any comments/criticism as I tried to be as non partial and scientific about this as possible.
