and this is summer addon

now the room is 28C, outside 27C - 23:21
day outside is 41C, room is 34C - 12:00

I can't wait to come winter to overclock a little be more

I forgot to mention I use CGMINER 2.7.0 with kernel DIABLO

What sort of cooling are you using in your case/GPUs?  Those temps are crazy low.

send me pictures of your case, will help you to optimize cooling.
GPUs is

two are the same, I buy them in 7 days difference, and they are different revision

[freeAgent]

I don't have a cooling problem (card stays below 90c, it's a single-fan model), though your temps in the mid-60s are very impressive.  Having essentially an open-air case helps in that regard   I built my PC for silence and as long as I stay within acceptable ranges, I'm not too concerned about the temperature.  When I'm not mining, you can't tell my computer is on

[Fiyasko]

i run two HD 7950
they are different revision but that i run them



I hope I was helpful.

It would be helpful if you stated your settings, so far i see intensity CG miner 2.7, And diablo kernal, Im using those
Like holy hell, Your (according to that chart) hitting 547mh/s with a core of 1070
What is the "powertune" 15?

Fwiw im using this card http://www.newegg.ca/Product/Product.aspx?Item=N82E16814150601

Like I said before, I"m using a 7970, not a 7950, but I dropped the "-v 2" arg out, and I got +20MH/s. Try letting CGMiner decide what vectors are best.

v 1 seems to work the best, Bringing my memclock upto 1ghz gave me an extra 10mh/s

[crazyates]

Well just trying to throw it out there. This thread has me playing with everything I can to get the most MH/s.

[SysRun]

impressive. is that mineral oil immersed or what?

woo hoo!

Acutually, Shappires latest line of cooling is really good.
My XFX is running at core 1080, Mem 800, Fan 73%[4100RPM] Temp 78°C room ambient temp is 27°C
Inside a cheap $60 Xion case with 4case fans, 1PSU fan, 1 GPU fan, 1PciSlot CoolerFan for the GPU, One CPU LCU Radiator cooling fan
Now with Intensity 7 and 9 giving same results, I am mining at 510Mh/s

[crazyates]

I of 7 and 9 gave me similar results, but 13 gave me +10MH/s.

[nitrox]

i run my two HD7950 with .bat that content:

Code:

title MINING
cd cgminer
del *.bin
for /F "tokens=1-2 delims=: " %%l in ('time /t') do set hhmm=%%l.%%m
TIMEOUT /T 10

cgminer.exe 2>../log/logfile_%date%_%hhmm%.txt -k diablo -o http://pool.ABCPool.co:8332 -u XXXXX -p XX -g 1 -v 1 -w 256 -I 10 --auto-gpu --auto-fan --gpu-dyninterval 5 --gpu-powertune 10,10 --gpu-engine 500-1065,500-1170 --gpu-memclock 915,1020 --temp-target 65 --gpu-fan 42-85

i use logs for detailed monitoring

Seems to have worked... Sortof... It's really bouncy.. dropping 5 below and going 10 above..

Shame how i have to be clocked at 1080 to get the meager 511mhash/s
Why the hell is nitrox hitting 54x+ with a 1080 core clock... Im trying to use all the same settings that he's using..

Check your CPU usage. Anything 10 or higher, and I get 100% cpu bug.

16%cpu usage at I 13, on a 6core 3.8ghz cpu, with the affinity set to two cores

Yep that's 100% on one core. Mine was 33% on a tri-core AMD, so that'd be 100% on one core.

So whats with nitrox getting 54xmh/s....
I can mine at 1080 stabily, but i only get 515mh/s

[Badonkadonk]

try using diablo miner, im currently running 2 rigs with "DiabloMiner-Windows -o yourpoolhere -u username -p password -r 8337 -v 1 -w 256"

at 1100/675 and 1050/675 im getting 1150mh on each rig (2 cards in each)... could clock higher but using closed cases so temps get a bit high...

[meebs]

I'm running 2x 7950s

BFGminer... the only parameter I feed it other than pool info is -i 9,9

with core of 1075, voltage of 1135 and memory at 625 I'm getting 560 mhash each.

This is on a 2700k on a Z77x-ud5h motherboard while mining litecoin on the cpu.

That sounds about right.
