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

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.

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

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.

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

This version is my attempt to optimize the Keccak code as much as possible. 128-bit vector operations are used where possible. Unfortunately the core operations of Keccak are still 64-bit because Keccak is annoying. Speedup is pretty minor. My 7790 goes from 108 khash/s to 112 khash/s. This version doesn't use the vstore* functions and should work with very old compilers (not tested though).

Thank you again!! Increased my 7950s from 230Kh/s to 240Kh/s   also able to run -I 19 no errors

Edit:
With a little more OC on the gpu I'm now getting 260Kh/s per card! Woo thank you mikaelh!!!

No sweat... what do you use for sha256? I seem to do better for scrypt than sha256...

Epic man, you work so hard on this...I'll try it out and post back with results. Currently running at 223kh/s with my 7970.

Diablo kernel, and oc the crap out of my 7970: 1250mhz core and 1.19v and 75% fan on my Gigabyte 7970 WF3 OC. (non-ghz, old revision)
-g 1 -i 14
Kinda pointless, but well...not doing it anymore but I did have the fastest 7950 and 7970 for sha256 out of the guys I know.

you should be able to get more out of your 7970.. im getting 260kh/s out of my 7950s right now

Thing is I only have 2gb of system memory, that severely limits me...should change in a week or so (getting some upgrades)

what speed are you running and where are you located? I might have some extra sticks of ddr3-1333 i could send your way

just sent you a PM..

Don't know why but this last version bumped the hashrate from 150 to 230 for my Sapphire 7950.
Now I mine with almost the same settings as in litecoin but with lower intensity since it tops hashrate at 17 although I can run it at 19 without HW errors.

Good work.

Works fine on HD48x0 hardware, though performance increase is hardly noticeable.
