Primecoin GPU miner: 9.1 CPD on a 280x / pool / 2% dev.fee

[drozenski]

Primecoin GPU miner ver. 1.03
-----------------------------
Mining time: 12.22 hours
Est. Average Chains Per Day (CPD): 1.72
Est. Spot    Chains Per Day (CPD): 1.68

Wow. What's you hardware (GPU/CPU)?
What version of Catalyst do you have?

I have a brand new ASUS R9280X-DC2T-3GD5
http://www.newegg.com/Product/Product.aspx?Item=N82E16814121803

OC Settings are

GPU Core 1196
GPU Voltage 1182
Mem 6900
Power target 110%
55% fan speed
Rock solid at 73C

My CPU is a I7 4770K

I am using the -CPU=9 flag. 20% cpu usage.

Cat 13.9 Drivers

I have the exact same card. How do you enter these settings?

Download GPU tweek from the ASUS website.

That's crazy with 1.72 CPD, did the same clock core and memory, and it didn't move from 1.55 CPD.

its not always about core/mem clocks some gpu are just more eff than others same with mem and latency eg  no 2 same model cards are going to have the same speed at same clocks

this rule goes for any silicon chip asics too

it about where it was cut from the wafer center chips will use less power where outer will use more if you use gpu-z it will show you asic quality

plus there are other factors here as in mobo cpu ram etc

same with cpu's the cache speed and latency can make a world of difference its not always about size
usually chip that have big amount run slow latency timings

True, just like cars, 1 out of 5 is usually the better performer per batch of cars.

The 280x does have a slightly better memory system than the 7970's, but not by much. Core's are basically the same.

i was getting 1.53 - 1.55 stock before the over clock.

actually the only thing changed was the pcb and componets used everything else is the same all manufactures choose different memory brands like elpida or hynix  and the difference between them are usually latency thats why some 290 series are faster than others but thats always a guess to which brand you might get like i have a asus 290x that used elpida where my 290x from visiontek used hynix so actually the crappy brand is faster go figure

but if your good with bios modding like me you can change the times to be tighter just like you can with desktop ram

How can you do that? Would be fun for benchmarking at hwbot :p

Btw, 14.4 sucks for mining...I'll revert to 13.9 me thinks.

Awesome!!!

You gave me something to do on the weekend now...fun stuff.

EDIT: I'm familiar with Stilt's method, but I thought he had a private tool, not available to the public.

Since we seem to be increasing difficulty quite quickly, is the mining client configured to mine efficiently once the difficulty hits 11? 
Won't 11 chains be the goal after we hit difficulty of 11?

[kev7112001]

hope everyone doesnt start mining on a pool and stays solo cause we dont need ypool having over 51%

Can someone address this?

What is the difference of difficulty 10.0 and difficulty 10.6? As an example?

If 10-chains are all that really miners are looking for?

0.6  ( that was easy  )

The question was directed at 10-chains vs. 11-chains. Once diff gets to 11.

~ 50x

~ 50x

Is that true for every single digit jump up in difficulty?

+1 in diff = x50 in difficulty?

[primer10]

i understand that it is pretty linear between 10.1 and 10.9 but exponential when 11.

[djm34]

what are the rate of findind an 11ch (and a 12ch) ?
Btw, It would be nice to increase the verbosity of the miner

https://bitcointalk.org/index.php?topic=251850.msg2757963#msg2757963

About 30x harder than the rate for finding 10ch.

Would anyone care to speculate where difficulty will level off?  Will we get to 11 anytime soon?

Also, I found this profitability calculator for xpm.  You can see how blocks found changes as  difficulty goes up.     http://anty.info/primecoin-calculator/




Also, charts are fun: http://xpm.muuttuja.org/charts/

My miner isn't working anymore after changing drivers from 14.3 to 14.4 and back to 13.9 last night...



Any tips? Do I need an updated license?

Did you try the AMD clean up utility?

14.3 works well, about the same as 13.12 for me.

Jst sinc your wallet

[ivanlabrie]

Synced...though, I found out it's not mining some other coins properly either.
Gonna have to reinstall it seems. And yeah, I tried the cleanup utility, will have to do it all over again.
