Title: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: Reckman on January 09, 2014, 07:45:38 PM Has anyone seent this?
I know there is variance and estimated hash rates at the pool. But the discrepancy is huge. Is there something with my CGminer config? CPU and Ram are well below capacity. CGminer is stable. Thanks for your help. https://i.imgur.com/BzITems.png Code: , Title: Re: CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: Reckman on January 09, 2014, 10:30:36 PM o.O
Title: Re: CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: cryptomining on January 09, 2014, 11:28:05 PM thats not variance, you got problems for sure, you should have 0 hardware errors and at least double wu. what gpu's?

The pool is estimating your hashrate. Imho there is an issue on their side. Cgminer is 100% accurate on your hashrate, pools are estimating it based on the shares you submit. Change pool and it should be fixed. Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: Reckman on January 10, 2014, 02:24:25 AM I have tried another pool,
look at the WU variance, the hash rate shouldn't be the same with WU of 50% more. Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: _destro on January 10, 2014, 03:58:26 AM Well, generally, HW errors means that the card is being pushed too much in some way. Lowering the intensity seemed to help a bit, but I'm suspecting the memory clock might be a little too high. Some of these R9s can be pushed quite a bit on the memory/core clocks, and some can't. I have a few R9 290s that are rock solid at 1500, and 2 others that don't like anything above stock.
Try this: "gpu-memclock" : "1350" If that seems to clear up the HW errors, and the WU is pretty close to the reported hashrate, I'd toy with bringing intensity back up to 19. I'd also try to slowly increase the thread concurrency. Many of these R9 270s can get up to 16000 TC.

Set lookup-gap to 2. Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: ymer on January 10, 2014, 05:58:47 AM I'm pretty sure it's the pool, make a quick try on a different one.
Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: maardein on January 10, 2014, 09:06:53 AM I think your thread concurrency might be the problem. First, you don't need to set shaders and thread concurrency (tcc), since cgminer will automatically determine tcc when you set shaders. So, I would delete the tcc line, and keep the shader line.
Also lookup gap at 2, like suggested before, could be a good start. Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: bmoconno on January 12, 2014, 01:17:06 AM The discrepancy you're seeing in cgminer's reported hashrate and the hashrate reported by the pool is a direct result of the HW (Hardware Errors) that your cards are producing. The number of HW should always be zero when scrypt mining.
I'd bet dollars to doughnuts that all those hardware errors are the result of running Powertune @ 20 on all four cards. Here's how I would resolve this problem: (NOTE: IGNORE YOUR HASHRATE WHILE WE TRY TO REMOVE HW ERRORS)
If cgminer is now running without HW errors, I would recommend (as others have suggested) increasing your thread-concurrency to 16000. If you previously had problems doing this, the variable commands (setx) I had you enter should have resolved that. From there, I would either slowly iterate values for settings (gpu-engine/powertune) until you get your hashrate at an acceptable level with zero HW errors. Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: damiano on January 12, 2014, 02:03:13 AM Im using a R9 270x as a backup atm and your config is way to aggressive.
I do about 390-414k I 15 powertune 0 then 10 try it out Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: mikeyfinn on January 12, 2014, 02:31:26 AM Did you say a gigabyte 270x? if so, try this for options:
-I 19 -g 1 -w 512 --lookup-gap 2 --thread-concurrency 15232 --gpu-engine 1130 --gpu-memclock 1500 --gpu-fan 85 this is what i use and i get ~480 with no HW errors Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: Reckman on January 12, 2014, 02:34:36 AM they are regular 270 cards not 270x
running stock still gives some errors and shitty WU Code: "intensity" : "13,13,13,13", Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: Reckman on January 12, 2014, 02:50:04 AM Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: mikeyfinn on January 12, 2014, 02:54:05 AM http://pastebin.com/1BfDXwS7
Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: mikeyfinn on January 12, 2014, 03:15:15 AM "-I 17 -g 1 --thread-concurrency 12000 --lookup-gap 2" that should get you ~450 Kh/s,
hopefully with no HW errors. Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: Reckman on January 12, 2014, 03:20:37 AM bmo and mikeyfinn had answer
it was thread-concurrency, but I had messed with it before and It caused crashes, I think removing the BINS helped I'll send bounties thanks Title: Re: [.05 BTC Bounty] CGMiner Hash Rate vs Pool Consistently 50% at Pool Post by: mikeyfinn on January 12, 2014, 03:26:25 AM Thanks much, and glad you are up and running!
