[ANN][Pool][Profit-Switch][Optional Auto-Exchange per Coin][Vardiff] ~ Hashcows

[induktor]

I don't go to Chinese websites and bitch that I can't read their service announcements.

LOL!!!!  

I will like to add, it is not responsibility for the hashcows admins to include other languages, the site is in english, deal with it, i am not an english native speaker either, and actually never studied it, learned by myself, and still have a LOT to learn, but i did, takes time and effort, now i need chinese mandarin, and I will learn it, it probably take me 5 to 10 years, but i will, so anyone can learn too.

may many times i need it to read german, french, italian or russian, i can get some of the first three, but with russian i am totally lost, so... google translator is your friend

BTW: any news on the new hashco site??, do you think it would be online today? (not pushing, just anxious hehe)

Dear aTriz and Nearmiss,

Please cut the vardiff rating, these 80+ WUs are so large they turn stale or are "jobs not found" before I can submit, resulting in 40% rejects again...sure it saves on a little server cost, but it's ruining returns for both you and us.

A=5790 R=2630

This is why I don't mine middlecoin, they force me to 512 and it's so costly when one of them fails. Please take this into consideration.

If the vardiff rating is not to blame, please figure this out. I have 90% less rejects when I straight mine a coin, even one you guys are mining at the same time.

Thank you,
Anubite

What is the combination of your cards and the hash rate?

What is the difficulty value?

For my 8 GPU 7990+7970 rig (5.6MH/s), the difficulty is 510 at the moment. Some times, it is 1000.

The total rejection rate is 8.9%. It is usually 1%. So maybe it is coin specific.

Yes it is coin specific, but on some coins I also get nearly 40% reject, due to HIGH VARDIFF please lower it.

I have 10x 7950 and depends on the coin the reject ratio goes from 1% to 40% due to high vardiff.

and in middlecoin the situation is even worse!, that's the main reason I use middlecoin only as a backup, because the very high difficutly results in a lot of work that goes nowhere, nearly 50% of the time is useless work.

I have 1 r9 290x from Sapphire, puts out about 904kh/s with stock cooler and a little tweaking. I use cgminer.

What are expiry, scantime, and hotplug?

(btw if you could help me figure out why bfgminer crashes my computer, there's 25 pxc in it for you )

This is my cgminer config:

(p.s. lol, litecoin is the most profitable coin to mine right now?! alt cleansing in progress, beware.)

Your 904 kH/s is very high already. You can get more configuration setting from the following website.

That is because you use 7950. In order for 7950 to perform faster, you have to use 1 GPU thread and high intensity. The higher intensity, the more work is going on in the GPU. So it takes longer to finish one task, causing rejection/stale. For example, intensity 19 has double the amount of work going on as intensity 18.

After I found this out, I stopped purchasing 7950. All my new GPUs are 7970 or 7990. They use intensity 13 and 2 GPU threads, which is equivalent to intensity 14, which is 1/32 (2^5) of intensity 19. They are more suitable for fast coins.

Interesting. Glad I am hitting the high end with my methods. I need to get another 3 of these somehow. Donations? (jk   )

Still, the fast moving, low network difficulty coins move too fast for "appropriate" difficulty, it seems. Maybe I am just a noob on that end, but it doesn't explain the lower rejects while mining the same coin on a dedicated server. Mayber there is a DDoS ongoing?

EDIT: Looks like something happened, i'm only getting 6-9% rejected now. I've been hopping to middlecoin now and then, had less rejects there for some time, but it's equal now. Woot.

Guys stop selling your LOT (lottocoin). It can't grow as a currency if you sell it. There are not enough buy orders to sustain the sell orders.

That's what just happened to my investments in phoenixcoin. Went down over 35% during the BTC boom yesterday. Many bailed and there were few buy orders, then a guy put up a low sell wall 1000x the normal sell transaction volume and it TANKED.

Out of the last 30 mining rounds, LOT only came up once, and the pool did not find a block.  Find someone else to blame for the low value of your latest favorite clone coin.

Since you're revamping the site anyway. Can you make it a bit more mobile friendly?

That would probably take them a lot longer, and we need the site online asap!! 

maybe someone else can make an app for mobiles for hashcows, and we all can pay for it (in btc of course)
however i am thinking that doing such a thing would be probably very difficult to make it secure.

don't know, I can't program anything out of assembler and C, high level language are way out of my league

For some BTC incentive, I would be more than willing to make a Hashcows app, when the API is available. Heck, I'd even open-source it. Android only though.

That would be epic.

I was just getting superb accepted/rejected ratios around 50:1, when suddenly over 70% became "above target" and rejected.

EDIT: Got better, then worse, then my difficulty spiked to 625, then it fell to normal and things got better again.

[joulesbeef]

I want to be a hashcow

[Pierre3400]

How are we doing on getting the site up and running.

Im getting close to 5500kh/s in rigs, but i wont run until i can make workers for them.

[Catswold]

Pool down.  Portent of something good, or just a problem?  Only time will tell . . .



. . . Pool up.  No portent.

The suspense is killing me...lol

[aTriz]

We are planning on tonight baring no setbacks! 

We want the new portal up as fast as you all do! Just gotta make sure everything is 100% before releasing.

[mdmedina07]

I just got to say woot! err MOOO!
