Excellent link. That’ll actually be helpful to the OP.

Yes 1.2 ;D

I noticed it has started updating now,

[quote name=“RIPPEDDRAGON” post=“46192” timestamp=“1387469172”]Take a look at my power optimization thread: [url=http://forum.feathercoin.com/index.php/topic,4176.0.html]http://forum.feathercoin.com/index.php/topic,4176.0.html[/url]
I am working on a guide but that will help for now. I am so pissed my new Gigabyte R9 280xs are voltage locked…I am going to have to flash each of the 2 bios to different voltages, one for power optimization and the other for max hash rate.
[/quote]
This is good info to keep on hand. As for unlocking the voltage, I was a bit turned off by it and worried that I’d bork the ROMs on these cards until I followed that process ([url=http://www.cryptobadger.com/2013/10/undervolting-in-linux-via-modified-bios/]http://www.cryptobadger.com/2013/10/undervolting-in-linux-via-modified-bios/[/url]) and found out how easily it’s done. And very, very effective.

Finally moved the rig out to the garage to take advantage of the sub-freezing temps outside and only now begun tweaking settings. Running at a thread concurrency of 8192 and intensity of 13 I’m getting 675 at 70deg C without even trying hard. Seeing your guide I think I need to bump TC to 21000whatever or something, see if that works.

BUT I’M MUCH RECEIVING MANY DOGE AT THE MOMENT AND DON’T WANT TO TAKE THE DOWNTIME or whatever

R9 280x
1.075v
engine 1060
mem 1500
730kH/s

All very useful suggestions.

Thanks!

Hi Friends,

On wemineftc pool, I am getting 25% less than
the calculator says… is it normal ? What
is your experience ?

(no HWs Rs around 0.5%)

Thanks in advance

the calculator in most pools counts blocks you’ll find in the average it shows you.

looks like its not connecting…are the ports correct and are they unblocked?

I personally wouldn’t touch GUI miner, just jump right to CGminer and learn to use that.

mining 1 video card at 361 m according to cgminer?

There’s your clue.

Let’s assume for a minute that you’re mining Feathercoin (you didn’t specify), and that you’re utilizing a pool (you didn’t specify).

If your GPU is doing mega-hashes instead of kilohashes, you’re mining sha256 instead of scrypt. Bitcoin is sha256, Feathercoin is scrypt.

Try adding --scrypt to your mining configuration when you start cgminer.

Thank you, much appreciated

Step 1: Got the parts in

Step 2: Get it installed

Step 3: Get it off the kitchen counter to keep the wife happy and start mining

I’ve debating putting my rigs on my 3 season porch, in MN it was -10F this week…

I’m running a p2pool (ftcpool.nl) mainly because its fun and educational.
Besides that it really looks like if there’s more coins to earn with p2pool…

Got this from coinaxis.com

P2Pool pros:

Decentralized
Less prone to attack
DDoS resistant
Hop proof
Zero pool fees
Control over your earnings
No counter party risk (If pool shutdown, or stole coins)
Healthier for the bitcoin & litecoin network
Can invite friends to join your pool
P2Pool cons:

Difficult to setup
Higher variance
Not asic friendly (this is getting better)
Central pool pros:

Easy to configure
Save mining earnings for higher lump sum payouts
Asic friendly
Central pool cons:

Centralized
Prone to DDoS attack
Counter party risk - Pool may shutdown, get hacked, or steal your coins

Expand the window larger and then press G
I want to see the values that is set for the card.

So just wanted to say, im tuning core voltage right now and difference between 1113mv and 1050mv is a whopping 100 Watts without hashrate drop so im now on 2 HD7970’s with 1,45mh/s hashrate and 560watts power usage

550 watts with 1.040v

Hey,

We have had a pretty crazy month in the crypto markets with a lot of ups and downs. Feathercoin has really been quite a stable coin in comparison to LTC & especially BTC and a great coin to mine.

Hopefully you have all done well so far and hopefully over the coming months we see Crypto becoming a lot more stable.

I have read this post and, i have gone to the Pool Block Finder Stats and i have seen that I have founded a block too !!

Somebody knows if we found a block, the pool pays more to the miner?

I would like to spend the FTCs in UK. C’mon minners!!!

The Sapphire R9 280x Dual X are very sensitive to heat and top out around 720 kh with 1.050 - 1.100 volt.

In Europe they are the cheapest.

I just got the Sapphire R9 280x Toxic with 3 fans on it and will see if I can get the reported 760+ kh on it but they are a little bit more pricey but if you shop around or get lucky like I did you can get them around the same price as the Dual X

A weird card. 3 slots?

Don’t think the buttons and switches on the card are compatible to any normal library on linux.

Its the Asus “extreme” series.
Gotta love em though, 770Khash, 70degrees, 40% fan speed, in a 24degrees room.

sorry to hear that midway i almost bought some FTC from this site myself but had to leave so forgot about it till i seen it right now. Is there any way for you to get your funds back?

I’d love to know how you set it up to do that, because I’m planning on setting up several rigs in the near future, and I don’t feel like doing the monitor shuffle for rig maintenance…
[/quote]

quite easy, search google for a (manual) dvi switch :) should not be too expensive (around 10-50$ depends on how many you want to switch). HDMI-switches or better HDMI-matrix-switches are a “little” more expensive (100-1000+$)

aah, thanks
