You cant run any card very near to it max.
You getting black screen coz of over clocking.
You have no way but to keep the clock rates, which doesn't crash.
In your case, it is 1260 for memory.
I used this miner & got ~318 if i run with aggression 18 , 945/1200.
& also found out decreasing memory speed reduces hash rate & also temperature.
So it seems if increase memory, hash rates increases.

Also, any ideas where I can view historical prices for Litecoin, say since its conception or over the last few months?
Can anyone provide an explanation for this query:
Since I lowered my clock speed to 899mhz and up'ed my mem clock to 1250 on my 5870's ive been getting a blazing speed of 375-400kh each, which was an improvement on the 325-350 i was getting on 970mhz and 1200 clock... however I seem to not be solving blocks at the rate I was doing previously. Obviously I understand the luck factor but previously I was solving around 10-15 blocks a day, but now Im lucky to even do a third of that.
any ideas?
also if I raised my mem clock to 1270-1299 my rigs will run for a few hours then glitch out (black screen), any ideas on how to combat this as Ive read that these cards can go up to 1300 clock anyway.

Wicked man... Im now getting a steady 760kh with that tweak... cant quite get 400 per card, but think thats due to latency with other people using my net too
How many hashes is it pulling at 970Mhz?
899Mhz Core and 1250Mhz gets 415KH/s
899Mhz Core and 1250Mhz gets 415KH/s

Hi,
Thanks for that info. I was playing with the clocks, if i pushed to 970 on my refference i was getting faster speeds than 900 but havnt tried it with my xfx board. I also realised that my cards were glitching if they were pushed beyond 1225 mem clock...
I was using 5870's last month. Each card was getting +400KH/s
Increase the worksize to 256
Concurrency 6144
Aggression 19 (if you are not using that computer)
Please note that most 5870 are hard limited to 900Mhz, if you go pass that, you will lose performance.
DONT try pushing it above 900Mhz, test it, you can see yourself. My 5870's were set to 899Mhz Core and 1299Mhz Memory. (Memory hard limit is 1300Mhz)
That way you can hit 415-430KH/s
Makes not difference what CPU you are using, just don't mine with the CPU at the same time, if you think you have to then make sure its not under 100% load, use less threads. Otherwise it will bottleneck your GPU's. I have 3 cards running on AMD Ultra Low Voltage u270. And 3 cards on Intel i7 setups, both get same hash rates, CPU usage is 1-3%

Im using atm 1 x 5870 refference and 1x 5870 xfx with an overclocked i3
i have more systems i want to add all being quad 5870 xfx cards.
atm i use agg 17 with 128 file size and concurrency set to 6000 something and 5 threads per gpu.
with my two cards im averaging 700kh but wish to up this to nearer 800.
my refference card is currenty clock at 970mhz with 1175 mem clock, and my xfx is 920 with 1200 mem clock.
i can push my xfx to 930 and mem of 1250 but i only get a couple of hours mining at a total of 800kh before is glitches out...
im thinking of switching to linux... any other ideas to tackle stability and increase kh?
What hardware are you using?
Increasing lookup gap, decreases the VRAM usage. Decreasing lookup gap increases the VRAM usage.
GPU Thread Concurrency also affects the VRAM usage.
Sharethreads, what ever you set it to, does't seem to affect your mining performance.
Aggression set to 19, is the fastest aggression setting I can use. Anything higher/lower performs worse.
But if you only have a one GPU, I do not recommend using that high aggression, you PC will become very unresponsive/slow.

Hi
My miners on my GPU are running well... I was wondering if someone could explain what the following are and what changes to speed, if any, they could make when changed:
1. GPU Thread Concurrency
2. Sharethreads
3. lookup gap
BTW Im using reaper v13
Thanks!

Coincidence?
I believe it is an intentionaly stimulated similarity
If you convert that do € or $ trough BTC fiat price, it will be even more interesting. LTC is running circles around BTC in volatility.

Nothing is ASIC hostile. Nothing.
Go read again the definition of ASIC please
Go read again the definition of ASIC please
It is my understanding that, in terms of cost-effectiveness, scrypt can be regarded as relatively ASIC-hostile.
Of course you could design a fast (relative to a desktop CPU/GPU) ASIC for scrypt, but because of the memory requirements of scrypt wouldn't it turn out to be way more expensive than a fast ASIC for, say, SHA-256?
It would be like saying "scrypt is computer hostile"...I do not mean "hostile" as in "an ASIC would be inefficient". That would be just ridiculous, and I'm sure we both agree on that point.
What I mean is, instead, that the transition to ASIC mining would bring a smaller speedup than it would for Bitcoin.
Suppose that for Bitcoin you spend X to build an ASIC and you get a speed ratio of Y relative to CPU model Z.
What I mean by "hostile" is that to get the same speed ratio relative to the same CPU model you would have to spend significantly more than X.

Why it should be more expensive?
Because the memory requirements of SHA-256 are virtually zero, and memory (the type of memory used for caches in particular) is not free.

By then there will be all sorts of new crypto currencies, so who knows if Bitcoin will still be the primary digital currency for daily exchanges.
Most likely if history is any indication it usually is never the first mover to the market that maintains the dominant position unless backed by government methods of intervention like patents, mandating their use, that type of thing so as you say who knows.
Well, if history is any REAL indication, most people are
Meanwhile, a strong corporate funded campaign will be launched to smear crypto-currency as a tool for terrorists ,drug dealers and child pornographers.
Again, the brain washed masses will pat themselves on the back for calling you in, and the scum continue to rule our lives.
Man, talk about jaded.
True enough you left out not just the implication of criminal activity but the inevitable ban on btc that would come to make it a criminal activity brought to you by the same actors you list here.
