hey ive been mining litecoins with cuda miner for the last few days successfully but my amd 290 came inand ive been trying to get setup with it. can anyone give me a hand?

my progress so far is downloading guiminer-scrypt and cgminer. using ejpool. the the mining programs are showing a hash rate but the ejpool dashboard shows no progress.


ok just a progress update to show im trying and not expecting to be spoon fed lol.

i created a batch file

cgminer --scrypt -o stratum+tcp://www.ejpool.info:3333 -u porkchop.porkchop -p psswd --shaders #### --intensity 13 --worksize 256 -g 1

it works but my cgminer reads way higher then the ej dashboard kh/s

Okay, so where and how is the best way to buy and sell Litecoins ATM?

What does it say on [R] and [HW] in CGMiner? [R] stands for rejects and [HW] stands for hardware errors.

Buy BTC from a site that uses a payment method you have then transfer it to and exchange you want to use and exchange it to LTC and do the same to cash out.

Hi all! Long time lurker, first time poster here. smile.gif I am looking for info on mining, and whilst there is a plethora of data on the subject, there's many conflicting views that I'm hoping someone can straighten out for me. For the most part, I'm interested in Litecoin & some sort of cpu mining which can run concurrently for the two systems I have at my disposal. Both are reasonably good overclocker's, and likewise, I have a pair of decently oc'ing gpu's to use with them.


The faster of the pair is a water cooled 4.8 Ghz 3570k with a 7950 TF3 that pops off a 24/7 stable 1290/1740 oc. Unfortunately, the mobo lost it's pci-e slot during a UEFI reset, and I'm waiting on AsRock to complete the RMA at the moment.

The secondary is a 4.3 Ghz 1090T under water, that hits 3200+ NB with a decent FSB oc, & an unlocked 6950 @ 925/1500 on the factory HS.



My questions are:


1.) Which is the most efficient o/s for mining? I have at my disposal win 8.1 x64, win 7 x64, win 7 lite, XP x64, XP x86, and a bunch of Linux distro's. Both are currently dual booting, soooo... Additionally, I can slipstream a win x64 install if you think it will help.

2.) How much system memory does cpu mining need, & does it benefit at all from running very fast memomini g ?

3.) Disk I/O speeds, any difference overall? I have several ssd's, a velociraptor, a sshd, and some plain Jane 7200/5400 rpm drives to use. What's the best/most efficient configuration?

4.) Which mining & pool is the best in your opinion for cpu (I'm aware of beeeeer being the best for Primecoin, but if there's any other type of cpu mining that's of greater viablity that can run concurrently with gpu mining...). Also what have you found is the best pool for Litecoin?

5.) Since I am down one mobo at the moment, can I run the 7950 simultaneously with the 6950, and should I run separate instances of the gpu miner program for each? Secondly, if so, how can I oc both cards independently? Never tried that before, so I'm a little in the dark on that.

________________________________________________________________________________________________________

6.) This is specifically directed at IvanLabrie. I've dl'd CgiMiner 2.11.4 as you recommended, along with the Catalyst 12.8 driver. My question is how it compares with Reaper? Although, I suspect that I already know the answer based on your earlier recommendation, I would just like confirmation if you don't mind.



Thanks for any help you guys can give, and have a great day! smile.gif
1) if youre cpu mining then use the 3570k and use take manager to only allow the program 3 threads so cgminer can operate in the background. Make sure to watch you cpu temp as these miners are like running prime95.

2)I know gpu mining doesn't and I m 95% sure cpu mining doesn't either.

3)this has virtually no effect at all except for when you're syncing your wallet. Use the most power efficient drive you can like a laptop drive is fine.

4)I use give-me-coins.com for ltc mining and beeeeer.org for cpu. I haven't tried mining the other cpu only coins but I know prime is pretty stable so ill stick with that.

5) yes you can run both card since the accept the same driver. You won't be able to CF of course but just use trixx to overclock them separately. Msi afterburner won't work for this.

6) I've never used it before since everyone said cgminer was more stable.


Edit 1) There are a few linux distros that are dedicated for mining and hash very well, but I do not think you get voltage manipulation. I havnt heard a lot about win 8.1 but I know 8 was working just fine. Win 7 is also just fine but I think xp is a no go.

LTC config for R9 290:
On a reference cooled Powercolor R9 290 I came up with this as a "quiet" set up that allows me to sleep (55% max fan speed). tongue.gif
And it does an average of ~720KH/s w/o downtime, while feeding three displays, although in 2D mode.


Please note that in this image I started mining (02:13am) with the fan capped at 55% and when I woke up (about 7hrs prior to taking the screenshot) I allowed max fan speed to go up to 66%. Average GPU clock speed is about 941MHz with the current fan profile.


Here's what the batch file looks like:
Code:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://europe.mine-litecoin.com --gpu-platform 1 -I 19 --thread-concurrency 23552
The --gpu-platform 1 tag is necessary because I also have a GTX 680 set up in the rig. Various work unit sizes weren't really to a huge benefit as well at these settings. Same goes for lookup gaps.


GPU configuration:
vCore offset: -44mV [may actually go for less, was too tired last night]
GPU clock: 975MHz /effectively about ~885MHz after throttling @ 55% fan/
Mem clock: 1250MHz
Power limit: doesn't matter
Max fan: 55% for reasons stated above. About 65% fan should be able to keep the GPU @ 975MHz in an ambient temp of ~15oC.

That's what I came up with after about two hours of reading and fiddling.
So I figured I'd share with you guys. thumb.gif


Any insight? (Keep in mind I'm on reference cooling and that my head is ~1.2 meters away from the open case at night.)

Btw, an intensity factor of 20 is utterly unstable on my card, with this cooler at least. rolleyes.gif
