[POOL][Scrypt][Scrypt-N][X11] Profit switching pool - wafflepool.com

[Zels]

@Zels
Have you tried your 750ti's across different pools? Are there any differences in the hashrate for X11?

No variance on diff pool.  But on my 750 need to restart ccminer every 2 or 3 hours else hashrate decrease from 2.1 to like 1.9 
Restart.bat (in  win scheduler every 2hours)

Code:

@echo off
taskkill /f /IM ccminer50.exe
ccminer.bat

Seeing fairly high rejects:

cpu1    nscrypt    10.36 kH/s (0.0%)    
cpu2    nscrypt    6.22 kH/s (0.0%)    
cpu3    nscrypt    2.07 kH/s (0.0%)    
gpu1    x11    313.14 kH/s (36.4%)    
gpu2    x11    2.99 MH/s (6.7%)    
gpu3    x11    3.05 MH/s (0.9%)    
Total    nscrypt    18.65 kH/s (0.0%)    
Total    x11    6.35 MH/s (5.4%)

Seems to be mainly (Job not found)
If this is due to X11 coin switcher might want to increase the grace period on shares submitted for previous coin after switch ...

A bug? :
gpu1    x11    1.59 MH/s (47.6%)

gpu1    x11    1.43 MH/s (50.0%)

GPU1 is a HD5450 doing 94KHs as show on the miner console ...

It seems that hashrates reported by waffle jump to unrealistic value whenever a share gets rejected ...

GPU2 and GPU3 are getting same jump in reported  hashrate when rejects above 0%

Snipped a bunch, and I'll check it out, but that part there stands out to me.  Your miner is still finding shares/working on work and submitting a full 9 seconds after being told to work on something else.  The "new block" at 57:53 is new work, and a share that it already knows is going to be rejected as stale a full 9 seconds later, it submits.  Not sure what is up there, but the leeway for accepting old work is somewhere near the 1sec mark (assuming 300ms to client, 50ms to switch work in miner, 300ms back to us), 9 seconds means something odd is happening.

Hmmm ... broken miner (sgminer 4.1.0 x11x13mod)? I am getting rejects (job not found) on all gpu's

switched gpu1 to nscrypt (vertminer) and running fine and dandy on it

For X11 what should "expiry" and "scan-time" be set at?

Still showing inflated hashrates on GPU2 and 3 when rejects above 0%..
Hashrate also inflated on nscrypt when rejects above 0 %

[Jynger]

I have "expiry" and "scan-time" set at "1". "queue" set at "0" and have TOTAL rejects at 0.5%

@PW , is the X11 profit and vsLTC on stats page jumping up/down (from 88% to 140%) because the huge X11 hashrate fluctuation (growth) and stats are calculated buy earned shares divided with total current hashrate, not with hash that actually solved shares, so lagging behind a bit on pool or is it global market X11 profitability that does such jumps?
Im asking because Id like to commit to X11 but scrypt-N shows better profit stability on your pool.
And great job you have done with your pool!

It doesn't have anything to do with current hashrate, only average hashrate over the time period.  So if the pool was at 1MH for half the day, and 2MH the rest, it would be earnings/1.5MH, the fluctuation is due to solving large value blocks.

Some of the blocks are very difficulty to solve for a pool of our size, so we'll have an hour or two of mining them (partial time), where we're not earning much profit (a ton of time spent mining, 0 of those blocks found), and during that time, profit will slowly slide down (say 100 -> 80), and as soon as a block is found, will jump way up to a higher value.  Judging by the time of your post, it also might be when you're looking at it, the first few hours of the day are always pretty large swings due to how short of a time period you're looking at

Hi, can you modify the api for different algos, currently only the balance info changes between the different api, so maybe a single api can show all the balances also just like each api is showing hashrates of all the algos, otherwise will have to access 3 (script/scriptn/x11 ?) api for just balances info.

Also can you add algo info in worker hashrates like in the wafflepool miner stats page.

There's actually a new API, its not 100% done (might be some bugs in it), but should be a good starting point: http://wafflepool.com/api/miner?address=XXXXXXX  Structure should be trivial to convert with obvious algorithm additions.

Has everything in one place, and will be where new stuff goes in the future.  Old one will be deprecated/removed at some point (maybe a month or so?).

great job pool waffle.
just switched 9x Asus R9 280x 's over to X11
3.5Mhs each!

keep up the great work

Guys,  should I be able to utilize the sphsgminer from lasybear  to mine x11 if I have the amd 13.1 techpowerup modded gpu driver installed,  or do I have to go to the amd 14.1 drivers?  I'm getting all hw errors and no accepted shares.   

My miner is running six sapphire HD7950 cards.  It shows them all hashing,  but getting nothing but hw errors.  I've changed a few settings and while searching for answers,  I saw that a lot of folks have had issues with a new 14.4 beta driver and went back to a 14.1 version.   

My modded 13.1 driver was a pain in the ass to get all six of my cards going to begin with, and it has worked for scrypt and scrypt-n,  so I want to ask if anyone is mining with the modded 13.1 driver before I start stripping it out and loading  a newer one. 


I can post my config,  but I'm actively changing it right now in hopes of solving my issue.

Hmm,  do you know if that driver will run six cards?  The driver that I am using now has been modified to do so.  (Because I'm running Win8. )

I'm reading through the x11/x13 miner thread for more clues,

( https://bitcointalk.org/index.php?topic=623409.280 )

and I'll probably start posting in there if I can't figure it out.

The last thing that I want to do is change anything with the current driver that I am using,  since it is modified to run all six of my cards.

deznuts, Blago

thank you guys I've already seen that post,
but I'm a dickhead, that was my oldest rig,
so I forget that I had installed Catalyst 13.1,
Now it's working.
So definitely for others, Catalyst 13.1 is not working at all with this miner.
Once again, thank you both.
