Topic: [ANN] Yet another GPU miner release! [YAC] - page 9. (Read 53369 times)
My 7870LE w/Tahiti chip 180khash
Those are the settings I use to run it, nothing left out. I do have 8 gigs of system ram cause it's cheap. I leave s, q and e alone. Half the time the pool communications crap out, so it's a problem on their end...
Oh and it's Win7.
Thanks man, I guess it's my ram holding me back. Same for scrypt in general, everything BUT sha256 which nets me 750kh/s
I'm stuck at 223kh/s with my 7970...not too bad though. My pentium d does 1kh/s
I'm getting that on my 7950's. Shouldn't the 7970 get a bit more? Just curious...
Care to share your settings ? I can't go beyond 150 with my 7950.
Also what are your readings for WU in cgminer ? (mine avg 160)
Code:
yacminer --scrypt -o http://pool -u x -p x -w 256 -I 16 --thread-concurrency 21712 --gpu-memclock 1040 --gpu-engine 0-1040
I set memclock low because it does not have an effect on performance which is very strange since scrypt is memory hard, guess that only a part of the algo is gpu optimized ATM.
I have also noticed that lowering the memory speed boosts my WU from 100/110 at 1490 Mhz to 140/150 at 1040 Mhz.
Here's my yacminer stuff:
Code:
yacminer --scrypt -w 256 -I 18 --lookup-gap 2 -o http://yac.coinmine.pl:8088 -u x -p x --thread-concurrency 41000
Using Visiontek 7950s, core at 1000 and mem at 1500, voltage at stock, fans at 80%. WU will be rough estimate since I had to restart yacminer... damn pool died on me, again.... things should level out in a couple hours:
WU: 362/m
tried I 19 and it didn't like it
How much system memory and is that win or linux?
I'm at 225-250 with my 7970, i 13, tc 18368, lookup gap 3 g 2. 2gb system memory won't allow me to set higher TC.
Quick question: what is the best s, q and e setting? I get pool is not providing work fast enough from time to time.

What's your driver version? I think your OpenCL compiler may be too old. It's also possible to get rid of vstore but I'm not sure how that would affect performance.
That's HD4870 on Windows XP, so the drivers and APP SDK are pretty old. This OpenCL 1.0 HW delivers ~100MH/s SHA-256 at 800MHz engine and maybe 120W power consumption. Not worth mining anymore unless you have free electricity. I think it can be used very well for scrypt-jane mining as it offers over 100GB/s of memory bandwidth.
Here's a quick version that doesn't use vstore. Only recommended for people who cannot compile v6.

Now getting from 20KH/s on HD4850 @ 700MHz engine & 2200MHz GDDR3 memory to 35KH/s on HD4890 @ 900MHz engine & 4000MHz GDDR5 memory. GDDR5 vs. GDDR3 makes big difference as I've expected. Maybe the code or settings can be optimised a bit more. HD4890 is supposed to deliver 1/3rd of HD7970 performance.
Code:
yacminer --scrypt --thread-concurrency 4000 --lookup-gap 4 -w 64 -I 16 --no-submit-stale --retries 10
The extra stream processors are often under utilized.
Thanks for your continued development with this Mikaelh.
+1N=10 settings for 560ti with no HW errors and v6 cl, 24kh
--scrypt --worksize 128 --lookup-gap 1 -I 11 --thread-concurrency 4192
Try higher thread concurrency and lookup-gap and then you'll be able to increase intensity.
You need a cudaminer :p

Parameters:
Code:
--device 0 --scrypt --worksize 256 --lookup-gap 2 -I 11 --thread-concurrency 8192 -o adress -u name -p pass
My current settings for a 7790 are:
Code:
--scrypt -w 128 --lookup-gap 2 -I 17 --thread-concurrency 12000
This produces about 109 kH/s after the latest N change.

It should literally be half the rate with all other settings being the same
If one had 360 khash before what should they expect now? Trying to tune my miner probably to maximize my hash rate. Best I can do before getting swamped with HW errors is about 160khash on a 7870LE Tahiti.
