bitcoin / litecoin mining

Does anyone have any idea what can cause huge amounts of stale shares?

I left my rig on last night mining CHN, at work now and can't remember the pool name (not a P2Pool one, had to register) and I got about 50% stale shares, and after a restart it seemed to be getting similar amounts when I left this morning.

Tried some P2Pool CHN mining for about 4/5 hours and never got any shares paid out either.
 
Whitty my card is rev 1.0 I don't think they are voltage locked only rev 2.0 are?

I'm getting 620 a card but not stable need to tweak my settings and my psu is a cheap and nasty 700w, I'm picking up a Corsair AX-1200i 1200W 80+ Platinum Certified psu today as I want add more cards

Everyone said my Gigabyte 7970s would be voltage locked. But the OC software that ships with them allows me to adjust voltage.
Did you test it at the wall?

Some will allow you to change values in software but it does nothing at the wall.

Yep.

Stales are rampant because of the hugely quick block times.

I'm back mining Feathercoin now - it got put on BTC-e.

I can't believe such a simple fork has gone through the roof.

Though I'll be creating my own coin fork on the weekend so we'll see.

that gets me 605 kh/s

There are 2 7950's though, I've got the gv-r795wf3-3gd revision 2 model

I also updated the firmware (which you shouldn't need to do)

Is that 605 kh/s per card, or for both?

I've got two 7970s and I get way more than that per card. I'm using guiminer (scrypt version), and have all the latest drivers and OpenCL.


It's only one card, I mean gigabyte makes two models of card.

You;ll have to start getting creative with your cooling when you start putting more cards in, also you should be aiming to run your PSU at 70-80% as that is where it is most efficient.
 
Yes I'm going to open case, riser extensions with a 30cm box fan blowing the hot air out eventually when I get my other cards

Make sure you give us the *wink wink* beforehand. We need to be in on your MonkeyCoins early on.
 
What do you guys think will happen to litecoins price when the gpu mining on bitcoin is useless when ASIC's are rolled out and they all move to litecoin and mt gox starts accepting litecoin?

Has to go up a fair bit I presume over time?

My opinion is LTC on mtgox can only be positive for the coin.

Opinions are divided over at bitcointalk forum.

I think a lot of the GPU power that had gone from mining BTC to LTC has been temporarily diverted to these new alt coins (FTC, CNC, RMC* etc).

What's the benefit of mining in the newer alt coins? They seem to be popping up everywhere but I see lite/bit safer to stick around long term
 
Anyone using GUIMiner Scrypt with a 7970?

Rebuilt my rig with one yesterday and am wanting the best settings to use, currently ranging between 550 - 600 khash with default "high intensity" settings, should be able to do better right?

I'm using GUIMinder Scrypt with two 7970s. I get more about 700 kh/s using "high intensity". But my second card only gets 85 kh/s?

Don't select crossfire in the drivers and don't put the bridge on is the first tip.

Is it just me or has litecoin difficulty fallen?
 
Yup has fallen slightly to 396. Probably the effect of people moving their mining operations into other alt coins.
 
Thanks for the help guys I'm gettin 680 kh/s stable now on 7950 at 67 degrees, gonna get a couple more of these cards seem to be a good price for that rate

Damn, thats what my 7970 is getting overclocked to 1125 (and at like 75 degrees)!

Are you using GUIMiner-scrypt or CGMiner etc on command prompt?

If so, what settings?
